Embodiment
Present embodiment proposes a kind of cluster multi call method of state management, comprising:
For UE and network side, distinguish different right of speech situations with four kinds of states respectively:
When right of speech Idle state (FLOOR_IDLE), current no user took right of speech and also do not have the user to carry out the right to apply for words, right of speech release flow process, UE and network side were in Idle state;
The right to apply for words attitude (FLOOR_SETUP), when UE and network side carried out the right to apply for words flow process, UE and network side were in the right to apply for words attitude;
Right of speech occupied state (FLOOR_SERVE), after the user obtained right of speech, UE and network side were in the right of speech occupied state;
Right of speech discharges attitude (FLOOR_RELEASE), and when UE and network side carry out right of speech when discharging flow process, UE and network side are in right of speech and discharge attitude.
Described network side comprises Access Network and/or core net.
Based on above-mentioned method of state management, present embodiment also proposes a kind of method of cluster multi call speech right modifying, realizes the right of speech management of cluster multi call business.
Described right of speech management refers to after the professional foundation of cluster multi call the management of carrying out for the distribution that realizes user's speech privilege.Specifically comprise: after group-calling service up-downgoing dedicated channel had been set up, trunking terminal user was pressed the PTT key and is the application right of speech, and discharging the PTT key is release speech right.Wherein, cluster multi call provides special uplink channel for the calling subscriber, and provides downlink dedicated channels for all are called, calledly like this can hear the caller voice.
Wherein, the right to apply for words request message of UE need to be in RACH(Random Access Channel RACH, Random Access Channel) in send to network side.This is because the called subscriber cannot use the special uplink channel of group calling, therefore uses RACH to send this right of speech request message.And the right of speech releasing request message of UE is to send to network side in the group-calling service special uplink channel.
Particularly, speech right modifying relates generally to following two-part content: 1, common right of speech management; 2, right of speech preemption management.
1, common right of speech management
Common right of speech management refers to, the current group calling right free time, the user initiates the right to apply for words and right of speech release, specifically comprises:
1) UE application sending the right words request message is transmitted to CN to Access Network by Access Network; CN sends right of speech and sets up message to Access Network, is transmitted to UE by Access Network again.After UE receives that right of speech is set up message, need to send right of speech foundation and finish to network side, informing network side UE receives right of speech foundation, and prepares conversation.After CN received that the right of speech foundation of UE is finished, signalling of bouquet group calling state was called to group calling.
2) UE sends right of speech releasing request message to Access Network, is transmitted to CN by Access Network.CN judge can release speech right after, send the right of speech release command to Access Network, be transmitted to UE by Access Network again.
Wherein, in the common right of speech management, network side judges whether UE can obtain the right of speech criterion, and comprising: a1) group-calling service is set up; A2) UE belongs to group-calling service group; A3) network side is in the right of speech Idle state.
Network side judges that UE whether can the release speech right criterion in the management of common right of speech, and comprising: b1) group-calling service is set up; B2) UE is that the current right of speech people of group calling or UE role in group calling are the keeper; B3) network side is in the right of speech occupied state.
2, right of speech preemption management
The right of speech preemption management refers to, current group calling right is occupied, and other users carry out the management that right of speech is seized.The basic principle of right of speech preemption management comprises:
When 1) user adds cluster group, need the role of distributing user in group.Different roles represents different priority.The user who only is higher than current right of speech person's priority just can seize right of speech, otherwise can't seize.
2) user seizes right of speech, and UE application sending the right words request message when network side is in the right of speech occupied state, after needing to discharge current right of speech, could allow this UE obtain right of speech to network side.
3) UE sends the right of speech request message to network side, if network side is in the right to apply for words attitude, then compare the priority of UE and current the right to apply for words UE: if UE is lower than the priority of current the right to apply for words UE, then the application sending the right words refuse information is to UE; If UE is higher than the priority of current the right to apply for words UE and without buffer memory right of speech request message, this request message of buffer memory then, direct initiation right of speech discharges flow process after the right to apply for words of current the right to apply for words UE is finished, and discharges complete backward UE and sends right of speech and set up message; If UE is higher than the priority of current the right to apply for words UE and network side this moment buffer memory right of speech request message, the priority that then compares again the UE of UE and buffer memory the right to apply for words, if UE is higher than the priority of the UE of buffer memory the right to apply for words, the request message of network side buffer memory high priority UE then is for low priority UE application sending the right words refuse information.
Wherein, network side judges that whether UE can seize the right of speech criterion, comprising in the right of speech preemption management:
C1) group-calling service is set up; C2) UE is higher than current right of speech person or is higher than the request message UE of network side buffer memory at the group calling medium priority; C3) network side is in right of speech occupied state, the right to apply for words attitude or right of speech and discharges attitude.
In addition, at above-mentioned group calling right after changing, network side also needs to send the current group calling state of message informing terminal called.For the called UE of access group calling, this message sends by the group-calling service downlink dedicated channels.For the called UE (for example be included in the current group, but not yet the UE of access group calling) of the access that lags, this message is transmitted at the cluster multi call DSCH Downlink Shared Channel.
