Follow-up, behind the group calling release message of the group calling chain of command of receiving base station side, the transmission of last cycle property.
2.4 colony terminal receives group calling and sets up message, and configuration detection at interval;
Colony terminal continues to monitor PDCCH at each TTI; If receive the PDCCH information of using the G-RNTI scrambling of separating out in the beep-page message; Receive the shared data on the corresponding PDSCH so, then said shared data is decoded, obtain decoded data.
If decoded data are that message is set up in group calling; Then message is set up in said group calling and sent to chain of command, the chain of command configuration is used to receive related entities and the context of TTCH, promptly disposes the relevant parameter of TTCH; And prepare to receive the group service data, message is set up in the group calling of receiving after ignoring simultaneously.
Simultaneously, getting access to after group calling sets up message, can also obtain transmission cycle and delivery time that the TCCH in the message is set up in said group calling, be assay intervals with the transmission periodic recording of TCCH, and said delivery time is recorded as detects constantly.Be directed against in the group calling transfer of data of this group follow-up; Colony terminal begins from said detection constantly; Need all not monitor the PDCCH of G-RNTI scrambling, and only get final product, obtain corresponding group calling data then at the PDCCH of each assay intervals monitoring G-RNTI scrambling at each TTI.
For example, the transmission cycle of said TCCH equals 5ms, detects group calling constantly at A and sets up message, then A is the detection moment constantly, and assay intervals equals 5ms, then begins constantly from A, and every separated 5ms monitors PDCCH, obtains the group calling data.
2.5 the group-calling service data are sent in the base station;
The group-calling service data according to the transmission cycle T up of pre-configured TTCH, when reaching the transmission cycle T up of TTCH, are sent according to the group-calling service type in the base station.
Wherein, said group-calling service data are periodically to send equally.
2.6 colony terminal receives the group-calling service data;
Colony terminal begins from said detection constantly; Detect PDCCH in each assay intervals; If receive the PDCCH information of using the G-RNTI scrambling of separating out in the beep-page message; Receive the shared data on the corresponding PDSCH so, then said shared data is decoded, obtain decoded data.
If decoded data are the group-calling service data, then said group-calling service data are sent to service surface.
2.7 the group calling release message is sent in the base station;
The base station when reaching the transmission cycle T cp of TCCH, is sent the group calling release message according to the transmission cycle T cp of pre-configured TCCH, discharges the group calling chain of command and the service surface entity of base station side simultaneously, and this time group-calling process is accomplished.

Wherein, Lag to insert and be used to guarantee that colony terminal can receive the data on the respective channels; For example, if colony terminal causes temporarily can not receive TPCCH, TCCH, the last data of TTCH owing to getting into the district that declines deeply, so when signal recovers; Owing to the assurance that lags and insert is arranged, still can receive group-calling service again.
In the existing base station scheduling strategy; Cluster multi call business and public network service are not distinguished; The cluster multi call signaling traffic requires colony terminal to detect G-RNTI; And public network service requires colony terminal to detect C-RNTI (Cell Radio Network Temporary Identifier, Cell Radio Network Temporary Identifier/Identity, Cell-RNTI).Therefore cause colony terminal all to detect G-RNTI and C-RNTI, and then cause colony terminal burden when supporting digital cluster functions bigger, and colony terminal consumption rate when detecting data is bigger at each TTI.
The application is provided with the transmission cycle of TCCH and TTCH according to business features, and has disposed the relation in the transmission cycle of TCCH and TTCH, makes that colony terminal can be only in assay intervals, and the transmission that promptly reaches TCCH detects G-RNTI during the cycle.
To the group-calling service of this group, when reaching assay intervals, when the Tcp of corresponding certain group of TTI of promptly eating dishes without rice or wine sent opportunity (TCCH sends the cycle), the relevant data of group calling were only sent in the base station, and other business datum is not sent.Can guarantee that like this colony terminal only need detect G-RNTI in the transmission cycle of TCCH, only detect C-RNTI, reduce the overhead that need detect a plurality of RNTI simultaneously in other the time interval.
Wherein, the transmission cycle of TCCH and TTCH sets up message through group calling and is configured.And, if need transmit the data on TCCH and the TTCH simultaneously, can be in a MACPDU with two kinds of data multiplexs.
Wherein, MAC is Medium Access Control, media access control layer; PDU is Protocol Data Unit, protocol Data Unit.
The base station is an insecure transmission through the process that TCCH signaling message notice terminal discharges group calling; The group calling release message that is the base station only sends once; If colony terminal is not received said group calling release message, just think that current group calling does not finish, the group calling that then can't discharge this connects.During follow-up group service of initiating again to this group, colony terminal can not remove to detect the group calling beep-page message again, can ignore the group calling that receives simultaneously yet and set up message, is equivalent to this colony terminal and has broken away from this group.Follow-up group-calling service can't carry out.The application has proposed a kind of solution to this problem.
Preferably, if in several assay intervals, do not listen to the information in the Physical Downlink Control Channel, then discharge group calling and connect.
Specifically comprise:
If continue not detect the information on the Physical Downlink Control Channel in the assay intervals, then detect the group calling beep-page message;
If in assay intervals, do not detect the group calling gating message times and surpass threshold value, then discharge group calling and connect.
In order to satisfy the demand lag and to insert, message is set up in the group calling beep-page message that TPCCH is last and the group calling on the TCCH all can be according to the cycle transmission that circulates, and behind base station transmission group calling release message, can stop to send the group calling beep-page message and message is set up in group calling.
According to These characteristics, if carrying out the colony terminal of group-calling service does not detect the G-RNTI scrambling when assay intervals PDCCH, then said colony terminal can detect G-RNTI in next assay intervals; If do not receive the PDCCH of G-RNTI scrambling equally; It is unusual to think that then group calling takes place, and continues to carry out this detection for several times, if there is not detected number of times to surpass the threshold value of configuration; Then the terminal can think that this group-calling service finishes, and discharges group calling and connects.
Certainly, behind the PDCCH that does not detect the G-RNTI scrambling, can also transmission cycle of TPCCH (or; Access period lags) remove to detect TP-RNTI; Can not think that equally group calling takes place unusually if receive TP-RNTI, continue to carry out this detection for several times, if there is not detected number of times to surpass threshold value (pre-configured detection number of times); Then the terminal can think that this group-calling service finishes, and discharges group calling and connects.
With reference to Fig. 3, provided the said group-calling service sketch map of the application embodiment.
Suppose: original TTI is 1ms; The transmission cycle T cp of TCCH is 5ms; The transmission cycle of message is set up in group calling, i.e. the access period that lags that message is set up in group calling is 20ms; The transmission cycle T up of TTCH is 10ms, the transmission cycle (5ms) of transmission cycle (10ms)=2*TCCH of TTCH.
Receiving first after the capable group calling of TCCH sets up message, with moment of said reception as detecting constantly, then assay intervals is 5ms.Promptly whenever detect the PDCCH of a G-RNTI scrambling at a distance from 5 sub-frame.
After this, said group calling is set up message and will be sent according to the access period that lags (20ms) circulation of configuration, and the access period that lags is here set up message through group calling and sent to end side.
0 to 9 this 10 sub-frame (original TTI) is 1 system-frame among the figure.To each system-frame, colony terminal needs each descending sub frame all to detect the PDCCH of G-RNTI scrambling in the prior art, and among the application, 2 descending sub frames that only need detect wherein get final product.And other descending sub frame can only detect the PDCCH of C-RNTI scrambling.
Wherein, if the configuration of cycle of TCCH is longer, need detect so the G-RNTI scrambling PDCCH chance just still less, promptly more dynamic service can be supported in centralization of state power terminal.
The group calling release message sends at 5 subframe places of n+2 system-frame; If colony terminal is not received said group calling release message; 0 subframe of n+3 system-frame can not received the group-calling service data on the TTCH so, can not receive that group-calling service data and the group calling on the TCCH on the TTCH set up message in 0 subframe of n+4 system-frame yet.If in pre-configured detection number of times, all do not receive these data always, just think that needing to discharge group calling connects.
In sum, in the prior art, the group calling release message only sends once, if colony terminal is not received said group calling release message, the group calling that then can't discharge this connects, and follow-up group-calling service can't carry out.And the application is not if receive the group calling release message that only sends once; When then can in several assay intervals, not detect the group calling data in the Physical Downlink Control Channel; The release group calling connects, and makes even without receiving that the group calling release message also can discharge group calling and connect.
