Embodiment
Fig. 1 is the flow chart of group service implementation method embodiment one of the present invention, and method described in the present embodiment mainly introduces the process of establishing of group service.As shown in the figure, the method comprises the steps:
Step 110, speaker's terminal sends group to core net and sets up request.
Particularly, as shown in Figure 2, group first can be set up request (PTTSpeakerRequest) and be carried on RRC connection establishment and complete in (RRCConnectionSetupComplete) message and send to base station, speaker side by described speaker's terminal, then this group's request of setting up to be carried in speaker's terminal (InitialUEMessage) message by base station, speaker side and to send to described core net.
Wherein, described RRC connection setup complete message sets up the message used when RRC signaling is connected between speaker's terminal with base station, speaker side.As shown in the figure, speaker's terminal first sends RRC connection request (RRCConnectionRequest) message to base station, speaker side, then RRC connection establishment (RRCConnectionSetup) message is sent by base station, speaker side to speaker's terminal, after being successfully established, then by speaker's terminal replies RRC connection setup complete message.Base station, speaker side is sent to by group's request of setting up being carried in RRC connection setup complete message, the deterministic process that RRC connection establishment is completed is set up the process of asking with initiation group and is carried out simultaneously, thus be conducive to the speed improving group service foundation further, reduce setup delay.
Step 120, described core net sets up according to described group the community, monitoring side that corresponding monitor terminal place is searched in request in the tracking area list preset.
Wherein, described tracking area (TrackingArea, be called for short: TA) in list, have recorded all signing current location of adhereing to the mobile terminal of group, because mobile terminal can change by occurrence positions in moving process, therefore want constantly to carry out real-time update to tracking area list.Particularly, described core net can first according to described group set up the group number of group to be set up that comprises in request and the CAMEL-Subscription-Information of described monitor terminal determine to add described in the monitor terminal of group to be set up; And then the community, monitoring side at described monitor terminal place is determined according to described tracking area list.
Step 130, described core net is that described speaker's terminal sets up speaker's resource, and simultaneously for group's resource is set up in the community, speaker side at described speaker's terminal place and community, described monitoring side.
Wherein, community, described speaker side refers to the community at described speaker's terminal place; Community, described monitoring side refers to the community at described monitor terminal place.Particularly, as shown in the square frame I in Fig. 2, when setting up speaker's resource, described core net first sends speaker's resource to the base station, speaker side in community, described speaker side and sets up request (InitialContextSetupRequest); After this, base station, speaker side is set up please set up speaker's resource for described speaker's terminal according to this speaker's resource.Detailed process when setting up group's resource will be introduced in subsequent content.
Step 140, when described core net receive first by community, described monitoring side base station, monitoring side reply group's resource be successfully established response time, for described speaker's terminal authorizes right of speech.
As mentioned above, base station, multiple monitoring side may be had will to set up group's resource, as long as but have a monitoring base station, side successfully to establish group's resource, then can converse, therefore authorize right of speech for described speaker's terminal, after this, user just can start speech by the speaker's terminal after acquisition right of speech.Detailed process will be introduced in subsequent content.
Shown in square frame I, II and III three sections of equal executed in parallel of signaling process in Fig. 2, as can be seen here, method described in the present embodiment by the Establishing process of executed in parallel speaker resource and the Establishing process of group's resource, thus substantially increases the speed of group service foundation, decreases setup delay.Experiment shows, adopts the setup delay after method described in the present embodiment to be less than 300ms.
Below introduce the process of establishing of the group's resource described in above-mentioned steps 130 in detail, concrete signalling interactive process, as shown in the square frame II in Fig. 2 and square frame III, as shown in Figure 3, comprises the steps:
Step 131, described core net first sends group respectively and sets up request (PTTInitialContextSetupRequest) to described base station, monitoring side and base station, described speaker side.
Because described monitor terminal may have multiple, and these monitor terminals are also likely scattered in different communities, monitoring side, therefore likely need to send described group to base station, multiple monitoring side and set up request, because length limit, only monitor base station, side for one in the present embodiment and be illustrated.It should be noted that herein, need when carrying out the monitor terminal conversed if also existed in community, described speaker side, then this community, speaker side now is also regarded as monitoring community, side and processes.
Step 132, (GroupPagingChannel is called for short: the group page message issuing the call number carrying group's resource configuration parameter GPCH) at respective group paging channel for described base station, monitoring side and base station, described speaker side.
Wherein, described call number is the identiflication number that group's resource configuration parameter distributes in advance, and different group's resource configuration parameters uses different call numbers.Because the data volume of call number is far less than the data volume of group's resource configuration parameter, therefore, transmits call number and compares than transmission group resource configuration parameter, be more conducive to reducing taking of Radio Resource, improve efficiency of transmission.
Step 133, the monitor terminal receiving described group page message in community, described monitoring side searches group's resource configuration parameter of this monitor terminal self preservation according to described call number, the described speaker's terminal receiving described group page message in community, described speaker side searches group's resource configuration parameter of this speaker's terminal self preservation according to described call number.
Wherein, preserve the corresponding relation of group's resource configuration parameter and call number in described monitor terminal and described speaker's terminal in advance, therefore, corresponding group resource configuration parameter can be found by call number.
Step 134, described base station, monitoring side and described monitor terminal set up described group resource according to described group resource configuration parameter in community, described monitoring side; Described base station, speaker side and described speaker's terminal set up described group resource according to described group resource configuration parameter in community, described speaker side.

It should be noted that herein, also the reason setting up group's resource is needed to be in community, described speaker side: even if before call starts, corresponding monitor terminal is there is not in speaker side in community, but carry out in process what converse, also new monitor terminal is likely had to add in community, speaker side, if now just start to set up group's resource, then the monitor terminal newly added in community, speaker side cannot access group in time, thus adds the wait time delay of call; Another reason is: speaker's terminal not holds right of speech forever, once right of speech is robbed, speaker's terminal originally also can become new monitor terminal, if now just start to set up group's resource, then the new monitor terminal produced cannot access group in time, thus adds the wait time delay of call.
As can be seen here, the present embodiment is when setting up group's resource, group page message is issued fast by group paging channel, directly carry out the foundation of group's resource according to group's configuration parameter after terminal receives group page message, and without the need to carrying out network interaction, therefore group's resource can be set up fast, the mutual time delay introduced of not eating dishes without rice or wine.
Below introduce the right of speech described in above-mentioned steps 140 in detail and authorize process, as shown in Figure 4, comprise the steps:
Step 141, core net authorizes (PTTSpeakerAccept) message through base station, speaker side to speaker's terminal to transmit call, and just speaker's terminal obtains right of speech.
Step 142, described core net sends right of speech instruction (PTTSessionIndicator) message respectively to described base station, monitoring side and base station, described speaker side.
By this right of speech Indication message, each base station, monitoring side and base station, described speaker side is made to learn current right of speech by which speaker's terminal is taken.
Step 143, right of speech occupied information is broadcasted respectively in described base station, monitoring side and base station, described speaker side on respective GCCH.
By this right of speech occupied information, each monitor terminal is learnt, and current right of speech by which speaker's terminal is taken.
