Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in connection with accompanying drawing, technical solution of the present invention is described in further detail.It should be noted that, in the situation that not conflicting, the feature in the application's embodiment and embodiment can combine arbitrarily mutually.
Embodiment 1
The present embodiment is introduced a kind of method that adds cluster group, and it realizes the process that adds cluster group mainly for non-right of speech subscriber equipment.Specific as follows:
When non-right of speech user device applies adds a certain cluster group, utilize the group identification of this group to receive the group paging message of this group, therefrom obtain the privately owned scrambling descrambling mark (T-RNTI) of this group;
Non-right of speech subscriber equipment receives group broadcast message on Broadcast Control Channel (TGCCH) channel of the group that will add, utilize the privately owned T-RNTI of this group obtaining to carry out descrambling to received group broadcast message, obtain group's shared channel configuration information, and be configured sharing data channel according to the content of group's shared channel configuration information, on this shared data channel, receive the descending shared data of trunked call.
It should be noted that, above-mentioned non-right of speech subscriber equipment adds the process of cluster group, also comprises the operating process of cluster Access Network side, and this process is as follows:
After group call is set up, cluster Access Network cycle on clustered paging channel issues group paging message, carries the privately owned scrambling descrambling mark (T-RNTI) of group identification and group in this group paging message;
Cluster Access Network, being that the Broadcast Control Channel (TGCCH) that this group independently sets up goes up, sends the group broadcast message of the T-RNTI scrambling privately owned with group taking group as unit, carry group's shared channel configuration information in this group broadcast message.
Wherein, group's shared channel configuration information that cluster Access Network sends on TGCCH is a piece of news of most critical in group's downlink broadcast control signal, and it at least comprises following three category informations:
1, the physical layer Radio Resource of group's downlink data shared channel TGTCH;
2, wireless data is carried on the bearing resource information of the each layer protocol stack of air interface;
3, other information, as the transparent transmission of the relevant information such as type of call, call property of core net appointment.
While more than foundation first for group, make the non-right of speech user of group add group by group's configuration messages of group paging and TGCCH.In addition, group's shared channel configuration information also has following application scenarios:
One, can carry out the foundation of the downlink broadcast data multi-bearing after group's foundation by this group's shared channel configuration information, amendment, deletes etc.
Two, cluster set up vertical after, the non-right of speech user of the cluster access that lags on the same group.
Add according to the method described above the detailed process of cluster group below in conjunction with concrete application scenarios explanation.
Suppose non-right of speech user privately owned DSCH Downlink Shared Channel configuration information of reception & disposal group on public group's DSCH Downlink Shared Channel, to complete the process that adds group call, particularly, this process as shown in Figure 2, comprises the steps 201 to 204.，
Step 201:eNodeB broadcasts group paging message by paging channel in community, carries the ID of group mark in this message, and the privately owned scrambling descrambling mark T-RNTI of this group.
In this step, sending group paging message object is in order to broadcast the existence of this group in community, and carries the essential information of access group call.
Step 202: terminal is received after group paging message on the same group, replys page-response message, and T-RNTI in group paging message monitors TGCCH channel as scrambler, resolves TGCCH channel massage to wait for the group's shared channel configuration information receiving on the same group.
Step 203:eNodeB receives the page-response message of terminal, if do not set up this group's example, set up this group's example and on TGCCH, send group's shared channel configuration information, and this group's shared channel configuration information carries out scrambling using the T-RNTI of this group as scrambler, meanwhile, be based upon eNodeB inside and set up the shared data channel of TGTCH.
Step 204: terminal monitoring TGCCH, carry out descrambling with identical T-RNTI, obtain this correct group's shared channel configuration information, therefrom obtain relevant radio physical resource information and wireless data beared information, set up with eNodeB and configure the shared data channel of identical TGTCH.
Can find out from above-mentioned flow process.Non-right of speech user and eNodeB have used the TGTCH of identical configuration, and this makes this non-right of speech user terminal can receive and resolve the downlink broadcast data that eNodeB sends on TGTCH, and like this, this user adds the process of group just to complete.
And Fig. 3 is shown in the effect of the downlink broadcast channel configuration message that guiding user adds group in whole flow process opportunity, as can be seen from Figure, this message is to trigger eNodeB foundation group example at page response, and eNodeB inside is set up and is sent after downlink broadcast Deta bearer channel TGTCH, that is to say, first eNodeB completes the foundation of self.
Non-right of speech user adds after group, and according to the flow process of LTE and characteristic, many Deta bearers are set up in the air interface support between eNodeB and terminal.Wherein, foundation, amendment, the deletion flow process of many carryings, be shown in Fig. 4, and it is similar with group Establishing process.
In addition, it should be noted that, because network side example and terminal use are not man-to-man relations, but the relation of one-to-many, therefore in trunked call, may exist after network side example set up, also have the situation of other non-right of speech users' accesses, for this user's the group that adds, be that dependence eNodeB issues group paging message in the mode in cycle and group's shared channel configuration information is realized.As shown in Figure 5, terminal can receive group paging message at any time, in the time that the group mark ID in discovery group paging message is consistent with self, further resolve the most basic resource T-RNTI of group calling in message, obtain after T-RNTI, resolve TGCCH signaling using this as scrambler, can resolve correct message must be the group configuration messages sending with identical T-RNTI, resolve correct after, can set up downlink broadcast Deta bearer TGTCH, carry out the time user that lags with this and add at any time group.
Cluster user adds group in a word, and method only has one, but the scene occurring may have a variety of.Wherein, in each scene, transmission TGCCH downlink broadcast channel configuration signaling all plays the effect of most critical.
