以上的网络架构是基于3GPP Rel6以前版本的架构,目前3GPP(3rd Generation Partnership Project)正在研究一种全新的演进网络架构,以满足未来十年甚至更长时间内移动网络的应用需求。 More than one network architecture is based on a previous version of 3GPP Rel6 architecture, current 3GPP (3rd Generation Partnership Project) is studying the evolution of a new network architecture to meet within the next decade or even longer, the demand for mobile applications network. 由于是一种全新的网络架构,因此现有架构的所有节点、功能、和流程都将发生实质性的变化。 Because it is a new network architecture, all nodes, functions, and processes of the existing structure will undergo substantial changes.

3GPP考虑到未来网络的竞争能力,目前正在积极研究一种演进的3GPP网络系统,目前有很多种演进方案在3GPP展开了讨论,网络演进的目的是希望提供一种低时延、高数据速率、高系统容量和覆盖、低成本、完全基于IP的网络。 Considering the future competitiveness of 3GPP networks, are now actively study the evolution of a 3GPP network system, there are many programs in the 3GPP evolution initiated discussion of network evolution aims to provide a low-latency, high data rate, high system capacity and coverage, low-cost, fully IP-based network.

现有的不同无线接入类型(Radio Access Type,RAT)间的移动性管理方案对于位置区的规划采用的是基于不同的接入技术的方案。 The mobility management scheme existing different wireless access types (Radio Access Type, RAT) between the location area of the planning is based on the use of different access technologies solutions. 如图3所示,长期演进(Long Term Evolution,LTE)路由区(Routing Area,RA)52为演进的E-UTRAN小区,2G/3G路由区50为传统网络中的UMTS或GPRS小区。 3, the long term evolution (Long Term Evolution, LTE) routing area (Routing Area, RA) 52 for the evolution of E-UTRAN cell, 2G / 3G routing area 50 as a traditional network UMTS or GPRS cell. 当作为移动终端的用户设备10在演进的系统架构演进(System Architecture Evolution,SAE)网络和传统的2G/3G网络间漫游时,用户设备10为了接收网络提供的业务,需要向网络侧发起路由区更新过程。 When a user of a mobile terminal device 10 in the evolution of system architecture evolution (System Architecture Evolution, SAE) time network and traditional 2G / 3G network roaming user device 10 in order to receive services provided by the network, the network side needs to initiate a routing area update process. 在这种网络架构下,用户设备发起的路由区更新流程如下:1)当用户设备10从2G/3G网络覆盖下进入演进的SAE网络覆盖下,用户设备10通过监听广播信道获得其所在的演进网络路由区标识(identify)信息。 In this network architecture, user device-initiated routing area update procedure is as follows: 1) when the user device 10 from the 2G / 3G network coverage into the evolution of the SAE network coverage, the user equipment 10 to get it in by listening to the evolution of the broadcast channel Network Routing Area Identity (identify) information. 发现与原有的2G/3G网络路由区标识不匹配,则用户设备10向网络侧发起路由区更新流程。 Found with the original 2G / 3G network routing area identity does not match, the user device 10 to initiate a routing area update process to the network side.

2)用户设备10发送一个路由区更新请求到MME/UPE(Mobility Management Entity,移动性管理实体;User Plane Entity,用户平面实体)82,消息包括原来的注册信息(如临时身份等,如果没有临时身份就用永久身份)。 2) the user device 10 sends a routing area update request to the MME / UPE (Mobility Management Entity, the mobility management entity; User Plane Entity, User Plane Entity) 82, the original message including registration information (e.g. temporary identity, etc., if no temporary identity on permanent status). 路由区更新请求还可以包括缺省IP接入承载(Access Bearer)信息(如用户优选的IP地址和APN)。 Routing area update request may also include a default IP access bearer (Access Bearer) information (e.g. user preferred IP address and APN).

3)MME/UPE 82将接收到的原注册信息发送给原来的MME/UPE 25以获取用户的信息。 3) MME / UPE 82 stores the received registration information to the original old MME / UPE 25 to obtain user information.

4)原来的MME/UPE 25发送用户信息(如永久用户身份)给新MME/UPE 82。 4) old MME / UPE 25 transmits user information (such as a permanent user identity) to the new MME / UPE 82.

5)用户设备通过新的MME/UPE 82进行鉴权。 5) a new user equipment via MME / UPE 82 for authentication.

6)新MME/UPE 82将自身注册成用户设备10的服务节点。 6) the new MME / UPE 82 will register itself as a service node 10 of the user equipment.

7)在原MME/UPE 25中用户设备10的信息将被删除,或者用户设备10被标志为不在本服务区。 7) in the original MME / UPE 25 in the information of the user device 10 will be deleted, or the user device 10 is marked as not present service area.

8)归属用户服务器(Home Subscriber Server,HSS)60确认MME/UPE 82注册成功,授权使用缺省IP接入承载的用户签约信息转移给MME/UPE 82,计费策略信息也随之转移到MME/UPE 82。 8) Home Subscriber Server (Home Subscriber Server, HSS) 60 confirmed MME / UPE 82 registered, authorized to use the default IP access bearer user subscription information transferred to MME / UPE 82, the accounting policy information can also be transferred to the MME / UPE 82.

9)选择Inter AS Anchor 70。 9) Select the Inter AS Anchor 70.

10)Inter AS Anchor 70配置IP层。 10) Inter AS Anchor 70 to configure the IP layer. 用户平面在UPE-Inter ASAnchor之间建立起来,并且使用缺省的计费和策略。 User plane between UPE-Inter ASAnchor set up, and use the default accounting and strategy.

11)MME/UPE 82将缺省IP接入承载的服务质量(Quality ofService,QOS)配置信息提供给演化的无线接入网络。 11) MME / UPE 82 will default IP access bearer quality of service (Quality ofService, QOS) configuration information is provided to the evolution of the radio access network. MME/UPE 82接受用户设备10的位置更新请求,并为用户设备10分配一个临时标识。 MME / UPE 82 accept user equipment location update request 10, and the user device 10 assigned a temporary identity.

12)MME/UPE 82确认用户设备路由区更新成功。 12) MME / UPE 82 to confirm the user device routing area update was successful.

从上面的流程可以看出,现有的不同无线接入类型间的空闲模式(LTE_IDLE)下的移动性管理方案存在如下的缺点:在空闲模式下,用户设备从2G/3G移动到SAE/LTE接入系统时,将发生位置更新的一系列过程,包括MME/UPE之间用户设备上下文(UEContext)的转移,MME向HSS注册,UPE向Inter AS Anchor做路由更新等,因此将导致一系列的空闲模式下的位置管理信令流量。 As can be seen from the above process, the mobility management scheme different existing idle mode between the wireless access types (LTE_IDLE) in the presence of the following disadvantages: in idle mode, the user equipment from the 2G / 3G mobile to the SAE / LTE When the access system, the location update of a series of processes, including a user device context between the MME / UPE (UEContext) transfer, MME registered with the HSS, UPE do routing updates to Inter AS Anchor the like, and therefore will lead to a series of location management signaling traffic in idle mode. 而由于演进网络建网初期E-UTRAN小区覆盖范围较小,随着用户设备的漫游,其在E-UTRAN和UTRAN、GERAN之间频繁移动,从而导致系统频繁进行位置更新的流程,极大地增加了空闲模式下的信令流量负荷。 And as a result of the early evolution of networking E-UTRAN network covering a small area, with roaming user equipment to move frequently between E-UTRAN and UTRAN, GERAN, causing the system to frequent location update process, greatly increased the signaling traffic load in idle mode.

[实施例一]在新的演进路由区(Evolved Routing Area,ERA)规划方案中,原有的2G/3G网络覆盖的区域仍保持原有的路由区规划,而演进网络覆盖的区域则采用和同地区的传统2G/3G网络联合规划的方式,形成演进路由区(演进路由区还可以自定义称为:统一(unified)路由区、联合(united)路由区、接合(joint)路由区、关联(associated)路由区、或组合(combined)路由区)。 [Embodiment 1] in the evolution of new routing area (Evolved Routing Area, ERA) plan, the original area of network coverage 2G / 3G routing area remains the original plan, and the evolution of network coverage area is used and Traditional 2G same area / 3G network joint planning approach, forming a routing area evolution (evolution can also customize the routing area known as: unity (unified) routing area, the joint (united) routing area, joining (joint) routing area, association (associated) routing area, or a combination of (combined) routing area). 在本实施例中,可以将原有的2G/3G网络视为第一无线网络,演进网络视为第二无线网络。 In the present embodiment, it is possible the original 2G / 3G network as the first wireless network, the evolution of the network as a second wireless network.

图7所示的是演进路由区规划示意图。 Shown in Fig. 7 is an evolved routing area planning diagram. 图中共有三种类型的网络覆盖:由无线网络控制器24管理的3G网络的UTRAN小区;由边界无线站(Edge Radio Station,ERS)84管理的演进网络的E-UTRAN网络小区;由基站控制器(Base Station Controller,BSC)28管理的2G网络的GERAN小区。 FIG. There are three types of network coverage: UTRAN cell by the radio network controller 24 manages the 3G network; E-UTRAN radio network cell station by a boundary (Edge Radio Station, ERS) 84 managed network evolution; by the base station controller GERAN cell (Base Station Controller, BSC) 28 Management of 2G networks. 其中由于BSC 28控制的GERAN小区为独立的传统2G/3G网络覆盖,则BSC 28下的小区按照现有的路由区规划方案,分解成多个路由区56。 Since the GERAN cell BSC 28 wherein the control is independent of the traditional 2G / 3G network coverage, a cell under the BSC 28 according to the existing routing plan area, routing area into multiple 56. 而无线网络控制器24控制的UTRAN小区和ERS 84控制的E-UTRAN小区覆盖同一地区,因此将UTRAN小区和E-UTRAN小区进行统一规划,形成统一的演进路由区54。 The E-UTRAN cell radio network controller 24 controls the UTRAN cell and ERS 84 controls cover the same area, so the UTRAN cell and E-UTRAN cell unified planning, unified evolution of routing area 54.

如图8所示,演进路由区由两部分组成:传统的3G网络覆盖下的UTRAN小区组成的路由区RA 56;演进网络覆盖的E-UTRAN小区组成的跟踪区TA1 58和TA2 59。 8, the evolution of the routing area consists of two parts: UTRAN cell under conventional 3G network coverage consisting of the routing area RA 56; evolution of E-UTRAN network coverage area consisting of the tracking area TA1 58 and TA2 59. 在演进路由区规划方案中,针对每一个演进路由区都定义一个路由区标识。 In the evolution of the routing area planning scheme for the evolution of each routing region defines a routing area identification. 考虑到演进网络从现有的2G/3G网络中平滑演进的需求,可以采用将演进网络覆盖的E-UTRAN小区并入到传统网络的路由区的方式规划演进路由区。 Considering the way the evolution of the network from existing 2G / 3G network smooth evolution of demand, you can use the E-UTRAN network coverage area incorporated into the evolution of the traditional network routing area planning evolution routing area. 即新增的E-UTRAN小区组成的跟踪区TA 58、59的标识直接采用原有的UTRAN小区组成的路由区RA 56的标识。 I.e., the new E-UTRAN cell composed of a tracking area identity TA 58,59 directly using the original UTRAN routing area identity of the cell composition of the RA 56.

当用户设备10在演进路由区中漫游时,无论是从传统的3G网络覆盖下的UTRAN小区漫游到演进网络覆盖的E-UTRAN小区,还是从演进网络覆盖的E-UTRAN小区漫游到传统的3G网络覆盖下的UTRAN小区,由于两种网络覆盖的位置区标识相同,用户设备10不会发起位置更新的流程,避免了由于演进网络建网初期E-UTRAN小区覆盖范围较小而导致的系统频繁进行位置更新流程和由此极大增加的空闲模式下的信令流量负荷。 When the user device 10 in the evolution of the routing area to roam, roam from both UTRAN cell traditional 3G network coverage under the E-UTRAN cell evolution of network coverage, or roaming the evolution of network coverage from E-UTRAN cell to traditional 3G UTRAN cell network coverage under two network coverage area due to the location of the same identity, the user device 10 will not initiate a location update process, to avoid the system due to the early evolution of the network to build a small network of E-UTRAN cell coverage resulting from frequent location update signaling traffic load processes and thus significantly increase the idle mode.

[实施例二]本发明在演进路由区规划方案的基础上,提出了一种根据策略优选无线接入类型驻留的路由区更新方案。 [EXAMPLE II] The present invention on the basis of the evolution of the routing area planning scheme, proposed a routing area update program resides wireless access types according to the policy. 优选技术的实现方法如下:将控制同一演进路由区ERA的服务GPRS支持节点(ServingGPRS Support Node,SGSN)和演进系统SAE MME/UPE规划为一个资源池。 Implementation preferred technique is as follows: the evolution of the control of the same routing area ERA Serving GPRS Support Node (ServingGPRS Support Node, SGSN) and the evolution of the system SAE MME / UPE plan for a resource pool. 在SGSN或MME的配置信息中增加一个3bit的字段,用于保留运营商配置的优选网络信息,字段设置方式为:000表示不优选网络;001表示优选E-UTRAN网络,当用户设备驻扎在此演进路由区ERA时,其上下文由池内的SAE MME保留;010表示优选2G/3G网络,当用户设备驻扎在此演进路由区ERA时,其上下文由池内SGSN保留。 Increase in the configuration information in an SGSN or MME 3bit field that is used to retain the preferred network configuration information carriers, field way: 000 means no preferred network; 001 represents the preferred E-UTRAN network, when a user equipment stationed here When the evolution of the routing area ERA, retained by its context pool SAE MME; 010 represents preferably 2G / 3G network, when the user equipment stationed at this evolution routing area ERA, its context retained by the pool SGSN. 同时,可以对本方案进行灵活扩展,只需要对该字段增加新的定义即可。 At the same time, this program can be flexibly extended only need to add a new definition of the field can be.

应用此种路由更新的方法,当优选E-UTRAN网络时,由于用户设备的上下文始终保存在演进网络侧,当用户设备处于E-UTRAN网络覆盖下时,可以便捷的获得演进网络的优质服务;而建网的初期则可以优选GSM网络,此时用户设备的上下文始终保存在SGSN中。 Application of this method of routing updates, when the preferred E-UTRAN network, due to the context of the user equipment is always kept in the evolution of the network side, when the user equipment is under the E-UTRAN network coverage, you can easily get the evolution of network services; The initial construction of the network can be preferred GSM network, then the context of the user equipment is always stored in the SGSN. 由于建网初期,E-UTRAN网络的建网范围有限,用户设备在绝大多数的情况下将处于现有的2G/3G覆盖下,保持用户设备的实际驻留网络和保留用户设备上下文的网络的一致性,有效的减小了用户设备上下文的迁移。 Because the initial network construction, building a network of E-UTRAN network range is limited, the user equipment in the vast majority of cases will be in the existing 2G / 3G coverage, the actual presence of the user equipment to maintain the network and keep the user's network device context consistency, effectively reducing the migration of the user of the device context.

类似实施例一,可以将原有的2G/3G网络视为第一无线网络,演进网络(E-UTRAN网络)视为第二无线网络。 Similar to Example one, can the original 2G / 3G network as the first wireless network, evolved network (E-UTRAN network) regarded as the second wireless network. 那么第一无线网络的核心网中的支持节点为SGSN,第二无线网络的核心网中的支持节点为MME/UPE。 Then the first wireless network core network support node SGSN, a second wireless network in the core network support node MME / UPE.

值得注意的是,本实施例的实现可以基于实施例一的实现,但是也可以在第一无线网络和第二无线网络播发的位置区标识不相同的情况下得以实现。 Notably, the next location area to achieve the present embodiment can be realized based on an example embodiment, but may be advertised in a first wireless network and second wireless network identity is the same situation can be achieved.

图9示出E-UTRAN为优选网络的情况下用户设备路由区更新的完整消息流程。 Full message flow of a user equipment a routing area update case of Figure 9 shows a preferred E-UTRAN network. 这是假设E-UTRAN网络被配置为优选网络,并且用户设备从另一E-UTRAN路由区漫游至该演进路由区的情况。 It is assumed that E-UTRAN network is configured as a preferred network, and the user equipment roams from another E-UTRAN case the evolution of the routing area to the routing area. 根据实际情况,也可能是2G/3G网络被配置为优选网络。 According to the actual situation, it may be 2G / 3G network is configured as the preferred network. 另外,用户设备漫游前所处的第三无线网络也可能是2G/3G网络。 Further, a user equipment roaming wireless network which may be a third 2G / 3G network. 该用户设备附着的流程描述如下:1)用户设备10漫游至演进路由区的UTRAN网络覆盖部分,通过比较广播信道下发的路由区标识与其保存的路由区标识,判决发起路由区更新流程。 The user equipment attachment process is described as follows: 1) the user device 10 roams to the evolved UTRAN routing area network covering portion, By comparing the broadcast channel sent routing area identity stored in its routing area identity, to initiate a routing area update judgment process. 用户设备10发送一个注册请求到SGSN 28,消息包括原来的注册信息(如临时身份等,如果没有临时身份就用永久身份)。 10 user device sends a registration request to the SGSN 28, the message including the original registration information (such as a temporary status, etc. If there is no temporary identity on permanent status).

2)SGSN 28将接收到的原注册信息发送给原来的MME/UPE82a,以获取用户的信息。 2) SGSN 28 stores the received registration information to the original old MME / UPE82a, to obtain user information.

3)原来的MME/UPE 82a发送用户信息(如永久用户身份)给SGSN 28。 3) old MME / UPE 82a transmits user information (such as a permanent user identity) to the SGSN 28.

4)用户设备10通过SGSN 28进行鉴权。 4) user equipment 10 via SGSN 28 for authentication.

5)SGSN 28检查其内配置的优选网络信息以及用户设备10的接入能力(是否能够接入演进网络),判决用户设备10应驻留在演进网络侧。 5) SGSN 28 checks within the preferred network configuration information and user equipment access capability 10 (whether the access network evolution), the decision should reside in the user device 10 is the evolution of the network side. 由于MME/UPE与演进的基站(Evolved NodeB,ENB)间是多对多的连接关系,因此SGSN 28应根据负荷分担原则选择一MME/UPE 82b,并向其发送用户上下文配置请求消息,请求该MME/UPE 82b为用户设备10生成MM上下文。 Because of inter-MME / UPE and evolution of the base station (Evolved NodeB, ENB) is connected to many relationship, so SGSN 28 depending on the load sharing principle should choose a MME / UPE 82b, and sends the user context configuration request message, requesting the MME / UPE 82b generates an MM context for the user equipment 10. 该消息包括,用户永久标识,用户的位置信息,安全信息等。 The message includes the user permanent identification, location information of the user, the security information.

6)新MME/UPE 82b将自身注册成用户设备10的服务节点。 6) The new MME / UPE 82b will register itself as a service node user device 10.

7)在原MME/UPE 82a中用户设备10的信息将被删除,或者用户设备10被标志为不在本服务区。 7) in the original MME / UPE 82a in the user device information 10 is deleted, or the user device 10 is marked as not present service area.

8)HSS 60确认MME/UPE 82b注册成功,用户签约信息转移给MME/UPE 82b,计费策略信息也随之转移到MME/UPE 82b。 8) HSS 60 confirmed MME / UPE 82b successful registration, the user subscription information transferred to the MME / UPE 82b, billing policy information also will be transferred to the MME / UPE 82b.

9)新的MME/UPE 82b接受用户设备10的网络附着,并且分配一个临时身份给用户设备10,并向SGSN 28确认用户上下文配置完成。 9) the new MME / UPE 82b accept user device 10 of network attachment and allocates a temporary identity to the user equipment 10, user context to SGSN 28 to confirm the configuration.

10)SGSN 28收到用户上下文配置响应消息后,向用户设备10确认注册完成。 After 10) SGSN 28 receives the user context configuration response message to the user device 10 to confirm the registration is complete.
