Feature can arbitrarily be combined with each other.
Embodiment 1
The present embodiment introduces a kind of method for adding in cluster group, is realized mainly for non-right of speech user equipment and adds in cluster
The process of group.It is specific as follows：
When non-right of speech user device applies add in a certain cluster group, the group of the group is received using the group identification of the group
Group paging message therefrom obtains the privately owned scrambling descrambling mark (T-RNTI) of the group；
Non- right of speech user equipment receives group broadcast on broadcast control channel (TGCCH) channel for the group to be added in
Message descrambles received group broadcast message using the privately owned T-RNTI of the acquired group, obtains group
Shared channel configuration information, and shared data channel is configured in the content for sharing according to group channel configuration information, herein
The downlink shared data of trunked call is received on shared data channel.
It should be noted that above-mentioned non-right of speech user equipment adds in the process of cluster group, cluster access net side is further included
Operating process, the process are as follows：
After group call foundation, cluster access net period on clustered paging channel issues group page message, the group
Group paging message in carry group identification and group it is privately owned scrambling descrambling mark (T-RNTI)；
Cluster accesses net in the broadcast control channel (TGCCH) independently established for the group, is sent as unit of group
Group is carried with the scrambled group broadcast message of the privately owned T-RNTI of group, in the group broadcast message and shares channel configuration letter
Breath.
Wherein, it is cluster downlink Broadcasting Control that channel configuration information is shared by the group that cluster access net is sent on TGCCH
The a piece of news of most critical in signaling includes at least following three types information：
1st, the physical layer radio resources of cluster downlink Data Shared Channel TGTCH；
2nd, wireless data is carried on the bearing resource information of each layer protocol stack of air interface；
3rd, other information, such as core net specify type of call, call property relevant information transparent transmission.
When being established for the first time for group above, pass through group paging and the non-right of speech of group's group configuration message group of TGCCH
User adds in group.In addition to this, channel configuration information is shared by group also has following application scenarios：
First, building for the downlink broadcast data multi-bearing after group's foundation can be carried out by sharing channel configuration information by the group
It is vertical, modification, delete etc..
2nd, it after cluster group is established, lags access with the non-right of speech user of cluster is organized.
Illustrate to add in the detailed process of cluster group with reference to concrete application scene according to the method described above.
Assuming that non-right of speech user shares in public cluster downlink receives the privately owned DSCH Downlink Shared Channel of processing group on channel
Configuration information, with complete add in group call process, specifically, the process as shown in Fig. 2, include the following steps 201 to
204.,
Step 201：ENodeB broadcasts group page message into cell by paging channel, and group ID is carried in the message
Mark and the group it is privately owned scrambling descrambling mark T-RNTI.
In the step, send group page message the purpose of be in order to broadcasted into cell the presence of the group and carry
Access the most basic information of group call.
Step 202：After receiving group page message with group terminal, page-response message is replied, and with group page message
In T-RNTI monitor TGCCH channels as scrambler, parsing TGCCH channel massages with etc. the group to be received with group share letter
Road configuration information.
Step 203：ENodeB receives the page-response message of terminal, if not established group's example, establishes the group
It organizes example and group is sent on TGCCH and share channel configuration information, and channel configuration information is shared with the group by the group
T-RNTI is scrambled as scrambler, meanwhile, it establishes inside eNodeB and establishes TGTCH shared data channels.
Step 204：Terminal monitoring TGCCH is descrambled with identical T-RNTI, is obtained the correct group and is shared channel
Configuration information therefrom obtains relevant radio physical resource information and wireless data carrying information, establishes and phase is configured with eNodeB
Same TGTCH shared data channels.
It can be seen that from above-mentioned flow.Non- right of speech user and eNodeB have used the TGTCH of same configuration, this so that this is non-
Right of speech user terminal can receive and parse the downlink broadcast data that eNodeB is sent on TGTCH, in this way, the user adds in group
The process of group just completes.
And effect opportunity of the downlink broadcast channel configuration message of user's addition group in whole flow process is guided to see Fig. 3,
As can be seen from Figure, which is to trigger to establish downlink inside eNodeB foundation group examples and eNodeB in page response
It is sent after broadcast data Bearer Channel TGTCH, that is to say, that eNodeB completes the foundation of itself first.
After non-right of speech user adds in group, according to the flow and characteristic of LTE, the air interface between eNodeB and terminal
More Deta bearers are established in support.Wherein, the foundation of multiple-bearer, modification, delete flow, see Fig. 4, it is similar with group Establishing process.
In addition, it is necessary to explanation, since network side example and terminal user are not one-to-one relationships, but it is one-to-many
Relationship, therefore in trunked call, it is understood that there may be network side example is established complete after, also other non-right of speech users accesses
Situation, be to issue group page message and group in a periodic manner by eNodeB for the addition group of this user
Shared channel configuration information is realized.As shown in figure 5, terminal can receive group page message at any time, when discovery, group is sought
Exhale group in message identify ID it is consistent with itself when, then further parse the most basic resource T- of group calling in message
After obtaining T-RNTI, TGCCH signalings are parsed in this, as scrambler by RNTI, and it must be with identical that can parse correct message
T-RNTI after parsing is correct, can establish downlink broadcast Deta bearer TGTCH, it is slow to carry out the time with this group configuration message that sends
User adds in group at any time afterwards.
Cluster user adds in group in a word, and there are one methods, but there are many kinds of the scene possibility occurred.Wherein each
In scene, send TGCCH downlink broadcast channel configuration signals and all play the role of most critical.
