Embodiment
The embodiment of the invention provides a kind of bearing processing method; After UE switches to E-UTRAN from GERAN/UTRAN; When existing the PDN that does not have default bearer to connect; Through revising the flow process that PDN that existing UE initiates connects the resource allocation that flow process or UE initiate,, the PDN that does not have default bearer sets up default bearer for connecting.
As shown in Figure 1, the flow chart for embodiment of the invention bearing processing method specifically may further comprise the steps:
Step S101, the default bearer that receives the UE transmission is set up solicited message.
At UE after GERAN/UTRAN switches to E-UTRAN; When the mobile management network element of network side finds to exist the PDN that does not have default bearer to connect; Mobile management network element sends indication information to UE, is not have the PDN connection of default bearer to set up default bearer with indication UE.Perhaps,
At UE after GERAN/UTRAN switches to E-UTRAN; The carrying that detects in some PDN connection as UE all is GBR (Guaranteed Bit Rate; Guarantee bit rate) carry; When perhaps detecting some PDN carrying in connecting and having TFT (Traffic Flow Template, data flow masterplate) all, UE also can determine to set up the indication that default bearer need not network side for the PDN that does not have default bearer connects so.Said GBR is meant the assurance bit rate, generally is used to describe the characteristic of dedicated bearing.And default bearer can only be shone upon by non-GBR (non Guaranteed Bit Rate, non-ensured bit rate) carrying.So when UE detects some PDN carrying in connecting all is GBR when carrying, UE can think that some PDN connects and do not have default bearer.Said TFT is meant the data flow masterplate, and this parameter is the IP traffic filter that carries, and is used for filtering different IP traffics, is not have TFT's for default bearer.So when UE detected some PDN carrying in connecting and all has TFT, UE can think that some PDN connects and do not have default bearer.At this moment, UE can decide in its sole discretion to the PDN that does not have default bearer connects and sets up default bearer and for example need not network side: the indication of mobile management network element.
After the indication information that receives the mobile management network element transmission; Perhaps UE decides in its sole discretion when not having the PDN of default bearer to connect to set up default bearer for some according to said method; UE sends default bearer and sets up solicited message to network side, and network side receives the default bearer of UE transmission and sets up solicited message.This default bearer is set up solicited message and can be carried by resource allocation request message or PDN connection request message that UE sends.This default bearer is set up solicited message and is comprised the default bearer indication information element; This default bearer indication information element can be default bearer indicator (default bearer indication); And the value that this default bearer indication information element can be set is that 1 o'clock this default bearer indication information element is effective, and value is that 0 o'clock this default bearer indication information element is invalid.When this default bearer indication information element is effective, show that resource allocation flow process or PDN connection flow process that UE initiates are to set up default bearer for the PDN that does not have default bearer connects.
Step S102, setting up solicited message according to default bearer is not have the PDN connection of default bearer to set up default bearer.
When the default bearer indication information element effective; The flow process of the resource allocation of initiating through UE is not have the PDN of default bearer to connect when setting up default bearer; The default bearer QoS (Quality of Service, service quality) that carries in the resource allocation request message of the mobile management network element of network side with the UE transmission is the default bearer Resources allocation as SDF (Service Data Flow server data stream) QoS.
Set up according to default bearer solicited message be do not have the PDN of default bearer to connect to set up default bearer after; The existing carrying that the default bearer that grouped data network gateway connects the PDN that sets up according to APN (Access Point Name, APN) is connected with this PDN is set up related.Be specially:
Grouped data network gateway is searched with the default bearer of setting up according to APN and is belonged to the existing carrying that a PDN is connected together;
This grouped data network gateway is according to the bearing identification that distributes for default bearer, with the default bearer of setting up with find to belong to the existing carrying foundation that a PDN is connected together related with this default bearer.Be specially: the bearing identification of the association of the existing carrying that the bearing identification that will distribute for default bearer connects as this PDN.
Searching according to APN with before the default bearer of setting up belongs to the existing carrying that a PDN is connected together, the bearing identification of the existing carrying that this grouped data network gateway can also connect according to this PDN detects the APN that PDN connects.
In addition; The embodiment of the invention judges whether the PDN connection corresponding with default APN sets up; Said default APN is meant the APN in user contracting data, and whether the default bearer that perhaps corresponding with this default APN PDN connects is set up, if do not set up; Then the mobile management network element of network side is set up default bearer through indication information indication UE, initiates to set up the flow process of default bearer.
In the foregoing description; UE switch to from the GERAN/UTRAN network E-UTRAN network after; The resource allocation flow process that connects flow process or UE initiation through the PDN that revises the UE initiation; Set up default bearer for the PDN that does not have default bearer connects, thereby to have guaranteed that the time PDN that existed that the GERAN/UTRAN network switches to the E-UTRAN network connects and can hold in the continuation of insurance of E-UTRAN network trunk.
As shown in Figure 2; Flow chart for bearing processing method embodiment one of the present invention; After UE switched to E-UTRAN from GERAN/UTRAN, when existing the PDN that does not have default bearer to connect, the embodiment of the invention one connected flow process through the PDN that revises existing UE initiation; Set up default bearer for the PDN that does not have default bearer connects, specifically may further comprise the steps:
Step S201, UE sends the PDN connection to mobile management network element and sets up request message.
This connection is set up request message and is comprised APN, PDN Address Allocation (PDN address assignment) and Protocol Configuration Options (protocol configuration option) cell.After GERAN/UTRAN switched to E-UTRAN, when the mobile management cell found to exist the PDN that does not have default bearer to connect, the mobile management cell can send an indication information indication UE to UE and remove to set up default bearer at UE; Perhaps; UE is through judging that some PDN carrying in connecting all is that GBR carries or some PDN connects whole carryings are when all having TFT; UE can decide in its sole discretion and set up default bearer so, and for example need not receive network side: the indication information of mobile management network element.In the embodiment of the invention, UE connects to set up at PDN increases an indication information element in the request message, and it is to set up default bearer for already present PDN connects that request message is set up in this PDN connection of indication mobile management network element.For example, the title of this indication information element can be default bearer indicator (default bearer indication), and this indication information element is effective when the value of this indication information element is 1, and value is that 0 o'clock this indication information element is invalid.When this indication information element is effective, show that through this indication information element it is to set up default bearer for already present PDN connects that this PDN connects flow process.
When this indication information element is effective, because connecting, PDN exists, so UE has obtained the IP address, so set up in the request message in connection, UE does not just bring network side with original PDN Address Allocation cell.
Step S202, mobile management network element sends default bearer to gateway and sets up request message.
Set up in the request message at this default bearer, mobile management network element passes to gateway with said newly-increased indication information element.This default bearer is set up request message and is comprised the bearing identification that mobile management network element is the default bearer distribution.
Step S203, gateway send default bearer and set up request message to grouped data network gateway.
Gateway is set up in the request message APN, PDN Address Allocation (PDN address assignment) and Protocol Configuration Options (protocol configuration option) cell at this default bearer, and said newly-increased indication information element and said bearing identification pass to grouped data network gateway.
Step S204, grouped data network gateway is set up the APN that request message comprises according to default bearer, this PDN is connected existing carrying set up related with the default bearer of setting up.
Grouped data network gateway is set up the value of indication information element in the request message according to default bearer, judges whether the indication information element that gateway passes over is effective.If this indication information element is effective, grouped data network gateway is set up the APN that request message comprises according to said default bearer so, this PDN is connected existing carrying set up related with the default bearer of setting up.
Set up association specifically can for: grouped data network gateway is searched with the default bearer of setting up according to said APN and is belonged to the existing carrying that a PDN is connected together; Again according to the said bearing identification that distributes for default bearer, with the default bearer of setting up with find to belong to the existing carrying foundation that a PDN is connected together related with this default bearer.For example: grouped data network gateway is with the bearing identification of the said distribution bearing identification as the existing bearing association that is connected with this PDN.
Step S205, grouped data network gateway carries out generating strategy and charging regulation alternately with strategy and charging regulation function entity.
Step S206, grouped data network gateway send and set up the default bearer response message to gateway, set up the user plane between gateway and the grouped data network gateway through this message.Downlink data can send to gateway by grouped data network gateway.
Step S207, gateway send and set up the default bearer response message to mobile management network element.
Step S208, mobile management network element send to carry to access network elements and set up request message.
Step S209, access network elements sends RRC (Radio Resource Control, Radio Resource control) connection to UE and reconfigures message.
Step S210, UE sends the RRC connection to access network elements and reconfigures completion message.
Step S211, access network elements send to carry to mobile management network element and set up response message.This moment, the up data link passage was got through.
Step S212, mobile management network element send to gateway and upgrade bearing request message.
Step S213, gateway returns the renewal bearing response message to mobile management network element.This moment, the downlink data link was got through.At this moment the default bearer of this PDN connection is set up and is finished.
Step S214, mobile management network element send to HSS (Home Subscriber Service, attribution assigned user server) and upgrade location request message, and packet data gateway address and APN are registered in the ownership place subscription data server.
Step S215, ownership place subscription data server return to mobile management network element and upgrade the position response message.
In the foregoing description; UE is after switching to the E-UTRAN network from the GERAN/UTRAN network; Through revising the PDN connection flow process that UE initiates; Set up default bearer for the PDN that does not have default bearer connects, thereby guaranteed that the GERAN/UTRAN network switches to after the E-UTRAN network, the PDN that has existed connects and can hold in the continuation of insurance of E-UTRAN network trunk.
As shown in Figure 3; Flow chart for bearing processing method embodiment two of the present invention; After UE switched to E-UTRAN from GERAN/UTRAN, when existing the PDN that does not have default bearer to connect, the embodiment of the invention two was through the flow process of the resource allocation of the existing UE initiation of modification; Set up default bearer for the PDN that does not have default bearer or do not have to be mapped to a default bearer connects, specifically to may further comprise the steps:
Step S301, UE sends a resource allocation request message and gives mobile management network element.
Comprise Linked Bearer ID (Linked Bearer Identifier in this resource allocation request message; Related bearing identification), Procedure Transaction ID (process interface sign), service database service quality SDF QoS and TFT (Traffic Flow Template, data flow masterplate) cell.After GERAN/UTRAN switched to E-UTRAN, when the mobile management cell found that the PDN connection does not have default bearer, the mobile management cell can send an indication information indication UE to UE and remove to set up default bearer at UE.In the embodiment of the invention, UE increases an indication information element indication mobile management network element in resource allocation request message, and this resource allocation request message is to set up default bearer for already present PDN connects.For example, this indication information element title can be default bearer indicator (default bearer indication), and on duty is that 1 o'clock this indication information element is effective, and value is that 0 o'clock this indication information element is invalid.When this indication information element is effective; Explain SDF QoS cell invalid or the indication do not bring mobile management network element with SDF QoS cell, at this moment mobile management network element can be with the default bearer service quality defaultbearer QoS that from CAMEL-Subscription-Information, obtains as SDF QoS.
Step S302, mobile management network element sends resource allocation request message to gateway.
Mobile management network element sends resource allocation request message to gateway; And (for example: default bearer indicator) effectively the time detecting said indication information element; Is the default bearer Resources allocation with default bearer QoS as SDFQoS, and through said resource allocation request message default bearer QoS is sent to gateway as SDF QoS.
Step S303, gateway sends resource allocation request message to grouped data network gateway.
Gateway sends resource allocation request message to grouped data network gateway, and through said resource allocation request message SDF QoS is sent to grouped data network gateway.
Step S304, grouped data network gateway sends strategy and charging control rule request message according to said SDF OoS to strategy and charging regulation function entity.
Step S305, strategy returns strategy and charging control rule with charging regulation function entity to grouped data network gateway.
Step S306, grouped data network gateway sends default bearer according to said SDF OoS to gateway and sets up request message.
Step S307, gateway send default bearer and set up request message to mobile management network element.
Receive that said default bearer sets up after the request message, mobile management network element default bearer for this reason distributes default bearer ID.
Step S308, mobile management network element send to carry to access network elements according to said SDF OoS and set up request message.
Step S309, access network elements sends Radio Resource control to UE, and (Radio Resource Control, RRC) connection reconfigures message.
Step S310, UE sends the RRC connection to access network elements and reconfigures completion message.
Step S311, access network elements send to carry to mobile management network element and set up response message.
Step S312, mobile management network element sends default bearer to gateway and sets up response message.
Mobile management network element will send to gateway for the carrying ID that default bearer distributes.
Step S313, gateway sends default bearer to grouped data network gateway and sets up response message.
Gateway sends default bearer to grouped data network gateway and sets up response message, and sets up response message through default bearer and will send to grouped data network gateway for the carrying ID that default bearer distributes.
Step S314, grouped data network gateway set up related with the default bearer of just having set up existing carrying after having received the carrying ID of default bearer.
Wherein, set up association specifically can for:
(1) in the resource allocation request message that UE initiates, carry the APN that this PDN connects, grouped data network gateway can be set up related for existing the carrying with the default bearer of setting up through APN so.Wherein, existing carrying refers to the carrying set up in the GERAN/UTRAN side.In this case, in resource allocation request message, with need not to carry related bearing identification Linked Bearer ID.Perhaps,
(2) in the resource allocation request message that UE initiates; UE with an existing ID who carries as Linked Bearer ID; Grouped data network gateway can detect the APN information that this PDN connects according to Linked Bearer ID, sets up related for existing the carrying with the default bearer of setting up through APN information then.Wherein, existing carrying refers to the carrying set up in the GERAN/UTRAN side.
Wherein, through APN for the existing default bearer that carries and set up set up association specifically can for: search with the default bearer of setting up according to APN and to belong to the existing carrying that a PDN is connected together;
According to the bearing identification that distributes for default bearer among the step S307, with the default bearer of setting up with find to belong to the existing carrying foundation that a PDN is connected together related with this default bearer.For example: grouped data network gateway is with the carrying ID of the default bearer bearing identification as the existing bearing association that is connected with this PDN.
Step S315, grouped data network gateway returns strategy and charging control rule response message to strategy and charging regulation function entity.
Step S316, mobile management network element sends location update request message to HSS, and packet data gateway address and APN are registered in the ownership place subscription data server.
Step S317, ownership place subscription data server upgrades response message to the mobile management network element home position.
In the foregoing description; UE switch to from the GERAN/UTRAN network E-UTRAN network the time; Through revising the resource allocation flow process that UE initiates; Set up default bearer for the PDN that does not have default bearer connects, thereby to have guaranteed that the time PDN that existed that the GERAN/UTRAN network switches to the E-UTRAN network connects and can hold in the continuation of insurance of E-UTRAN network trunk.
As shown in Figure 4; Flow chart for bearing processing method embodiment three of the present invention; The PDN that in a plurality of PDN connect, had both had default bearer connects; When existing the PDN do not have default bearer to connect again, because UE does not rely on the existence of default bearer in the UTRAN/GERAN network coverage time, so when UE switches to E-UTRAN; The MME of target side (Mobility ManagementEntity; Mobile management network element) can find that the corresponding PDN of default APN connects possibly not exist default bearer, even the corresponding PDN of default APN connects and do not exist, so need set up default bearer or the corresponding PDN of default APN that the corresponding PDN of default APN connects later on and connect when UE switches to target side E-UTRAN network at once.Need this moment network side to issue an indication information, the PDN that indicates UE to initiate an embodiment one description connects flow process or initiates the flow process of the resource allocation of an embodiment two descriptions.
Specifically may further comprise the steps:
Step S401, UE sends the tracing section updating request message and gives MME.
Step S402, MME upgrade for UE returning tracking district and accept message.
MME judges whether the corresponding PDN connection of default APN sets up, and whether the default bearer that the PDN that perhaps default APN is corresponding connects is set up.If do not set up; MME accepts the message the inside at tracing section updating so increases by an indication information; The value of default APN for example, perhaps independent indication information element, for example: default bearer for default APN (default bearer that default APN is corresponding); This cell value be set be 1 o'clock effective, value be 0 o'clock invalid.The embodiment of the invention is not limited thereto, and the indication information of the flow process of PDN connection flow process that embodiment of any indication UE initiation one describes or the resource allocation of initiating an embodiment two descriptions all should fall into the protection range of the embodiment of the invention.
In the foregoing description; UE switch to from the GERAN/UTRAN network E-UTRAN network the time; Through revising the flow process that PDN that UE initiates connects the resource allocation that flow process or UE initiate, set up the default bearer that the corresponding PDN of default APN connects, perhaps set up the corresponding PDN of default APN and connect; Thereby guaranteed that the GERAN/UTRAN network switches to after the E-UTRAN network, the PDN that has existed connects and can hold in the continuation of insurance of E-UTRAN network trunk.
As shown in Figure 5; Flow chart for bearing processing method embodiment four of the present invention; After UE switched to E-UTRAN from the UTRAN/GERAN network, when existing the PDN that does not have default bearer to connect, target side MME detects some PDN connection did not have default bearer; MME sends to UE and discharges the said indication information that does not have the PDN connection of default bearer so, and indication UE initiates a PDN and connects the flow process that discharges.Need accept in the message not only will the PDN that need to discharge to be connected the value notice UE of pairing APN at tracing section updating by MME; Also to increase an indication information; For example: release thePDN connection (discharging PDN connects) cell; Be used to notify UE to initiate a PDN and connect release flow, this cell value be set be 1 o'clock effective, value be 0 o'clock invalid.
The embodiment of the invention is not limited thereto, and the indication information of a PDN connection of any indication UE initiation release flow all should fall into the protection range of the embodiment of the invention.
Step S501, UE sends the tracing section updating request message and gives MME.
