Description
Technical field
The present invention relates to moving communicating field, particularly the service message treatment technology.
Background technology
Voice group call service (Voice Group Call Service, be called for short " VGCS ") and Voice Broadcast Service (Voice Broadcast Service, be called for short " VBS ") all be the voice communication mode that participates in many ways in the moving communicating field, break through the limitation of point-to-point communication, can set up calling fast.These two kinds of business can be referred to as group calling (or group calling) business.
Briefly, VGCS will realize that exactly a plurality of people can talk, and more people can be used as the business of hearer (hearer's quantity is unrestricted).
The professional member who comprises two kinds of identity in the VGCS business, i.e. dispatcher and service-user.The dispatcher can be that the fixed network user also can be the mobile subscriber, by network is the designated lane participation group calling Speech Communication of its foundation, at existing GSM 800M digital cluster system (GSM Trunk 800M, abbreviation " GT800 ") in the standard, the VGCS business can not have dispatcher or maximum five dispatchers; Service-user refers to the mobile subscriber of signatory VGCS business, and quantity is not limit, and participates in the group calling Speech Communication by the group calling passage in the group call region.
The VGCS business only permits a service-user at any time and maximum five dispatchers talk simultaneously, and other are not in the service-user of saying speech phase and are called the group calling hearer.The group calling hearer can be by pressing PoC (the Push To Talk on the portable terminal, be called for short " PTT ") key, realize robbing the operation of reverse link traffic channel according to the principle of " First come first served ", successfully can obtain speaking right participation speech if rob reverse link traffic channel, other group callings hearer has only the operation that just can continue to rob reverse link traffic channel when reverse link traffic channel is idle.The dispatcher has the designated lane of oneself, can participate in speech at any time.
VGCS permission user is established to the one group of user's who belongs to a certain specified services district and group identifier (Group ID) calling, and dispatchers all during the calling can make a speech, but all service-users are seized a data feedback channel.Service area can be by some (MobileSwitching Center of same mobile switching centre that belong to, be called for short " MSC ") or the sub-district of different MS C form, each related cell has a group calling passage during calling, wherein up link is only used (group emission mode) for current speaker, all hearers wait on down link (group receive mode), and relevant group calling notification message is gone up broadcasting at notification channel NCH (Notification Channel).
Relate to the group calling of a plurality of MSC, the management that one of them MSC is responsible for calling out, we are referred to as Anchor MSC, and other MSC is Relay MSC.Anchor MSC is responsible for setting up all connections, is included in the connection of the designated cell of this MSC, relevant Relay MSC and dispatching desk, and passes through the distribution that a meeting bridge is finished speech.Relay MSC only need set up a link to Anchor MSC, and Relay MSC is responsible for the distribution of affiliated subdistrict down voice.
VBS and VGCS business are similar substantially, and the main difference part is: have only call initiator to talk during VBS calls out, other members are in accepting state all the time.Spoken user need not be by the PTT key.
Mobile Origination group calling or broadcast ﹠ call, network side assign to other proprietary Traffic Channel (Traffic Channel is called for short " TCH ") with promoter's travelling carriage and go up speech when setting up the group calling control connection.For group calling, network side assigns to promoter's travelling carriage on the group-calling channel in the up back of release on the dedicated channel, and the proprietary TCH that took originally is released; For broadcasting, promoter's travelling carriage is talked on dedicated channel the duration calling out always.
Therefore, for the initiation of group calling, sub-district, promoter's travelling carriage place needs two TCH channels: the proprietary TCH channel that promoter's travelling carriage takies and the group-calling channel of sub-district; For broadcast ﹠ call, the duration calling out, sub-district, speaker's travelling carriage place needs two TCH channels all the time: the proprietary TCH channel that speaker's travelling carriage takies and the group-calling channel of sub-district.This implementation has caused certain waste to radio channel resource.
In the existing standard, when group calling or broadcast ﹠ call initiation, base station sub-system (Base StationSubsystem, be called for short " BSS ") can be revised as group-calling channel to the dedicated channel of group calling or broadcast ﹠ call promoter travelling carriage, and allow promoter's travelling carriage join the group-calling channel speech by the Channel Mode Modify process.This implementation can be implemented in group calling or the broadcast ﹠ call start flow, and a TCH channel only need be distributed in sub-district, promoter's travelling carriage place, has saved radio channel resource.
Yet to such scheme, clearly do not realize the signaling time-sequence that group calling or broadcast ﹠ call are initiated in the existing standard by the Channel Mode Modify process, because schema modification will be subjected to the constraint whether promoter's travelling carriage dedicated channel is set up, therefore possibly can't realize allowing promoter's travelling carriage join the group-calling channel speech by the Channel Mode Modify process according to the description in the existing standard.
