The method can avoid TCCH scheduling from falling into a unicast GAP period.

Description

TCCH scheduling method and device based on B-Trunc
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for scheduling a Trunking Control Channel (TCCH) based on a broadband trunking (B-TrunC).
Background
The group establishment flow is defined in the B-Trunc end-to-end protocol flow. After establishing the group resource, the base station notifies the UE of the group configuration information through a Trunking Paging (Trunking Paging) message and a group call configuration (GroupCallConfig) message on the TCCH channel.
The UE takes out the group ID and the group priority after receiving the trunk Paging message, monitors the PDCCH by using the G-RNTI, receives group signaling, namely the GroupCallConfig message, then establishes a group context, configures group resources and receives group service data.
The protocol specifies that the GroupCallConfig message carries a group inter-frequency measurement GAP (GAP), and the base station should avoid falling within the group inter-frequency measurement GAP when scheduling the group of services and the point-to-point data services of all terminals receiving the group of services. After receiving the G-RNTI R2 MAC CE of the UE, the base station ignores the pilot frequency measurement GAP of the point-to-point data service for the UE and enables the group pilot frequency measurement GAP parameter.
For a newly established group or a user who accesses the group later, if the user has GAP measurement, the TCCH may fall into the GAP, so that the user cannot receive the groucallconfig message and cannot monitor the corresponding group service.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the technical solutions of the present invention are described in detail below with reference to the accompanying drawings and examples.
In the TCCH scheduling method based on B-TrunC provided in the embodiment of the present application, a timer is set at a terminal or a base station side to suspend GAP measurement, so as to receive a GroupCallConfig message and monitor related group services. The method can avoid TCCH scheduling from falling into a unicast GAP period.
The following describes the implementation of the B-TrunC based TCCH scheduling procedure from the base station side and the terminal side, respectively, with reference to the accompanying drawings.
The base station side avoids the process of TCCH scheduling falling into the unicast GAP period.
Referring to fig. 1, fig. 1 is a schematic diagram of a process of a base station implementing TCCH scheduling based on B-TrunC in this embodiment. The method comprises the following specific steps:
step 101, when the base station issues a sounding Paging message, a first timer is started.
The timing duration of the first timer started in this step is:
T1＝mod(N×T2，T3)；
wherein, T1 is the timing duration of the first timer, T2 is the GAP measurement duration, N is the number of times of currently sending a trunking paging message, and T3 is the GAP period.
The T1 set in this way can avoid that the delayed time of the GroupCallConfig issuing is too long and falls into the next GAP period or the next TCCH issuing period.
And step 102, when the first timer is up, sending a group call configuration group call config message to the UE.
The implementation of the scheme can avoid that the GroupCallConfig message falls into the GAP period every time, and ensure that the UE starting the GAP measurement can receive the group signaling message to monitor the related group service.
The terminal side avoids the process of TCCH scheduling falling into the unicast GAP period.
Referring to fig. 2, fig. 2 is a schematic diagram of a process of implementing the TCCH scheduling based on B-TrunC by the terminal in the embodiment of the present application. The method comprises the following specific steps:
step 201, if the UE has started GAP measurement, receives a traversing Paging message, and a group carried in the traversing Paging message is a user subscription group, then starts a second timer, and suspends the current GAP measurement.
The UE initiated GAP measurements may be ongoing unicast GAP measurements, or may be ongoing GAP measurements for UEs that are listening to other groups.
When the UE starts the GAP measurement and does not receive the ringing Paging message in the process, the processing is realized according to the prior art.
And when the group carried in the trunk Paging message is determined not to be the user signed group, processing according to the existing implementation.
In a specific implementation of the present application, the timing duration of the second timer is greater than a group paging cycle.
Such a setting can prevent the timer from being set too small and the base station from timing out without issuing a GroupCallConfig message.
Step 202, before the timing of the second timer is overtime, if a GroupCallConfig message is received, stopping the second timer, and performing GAP measurement by using an inter-frequency measurement GAP of a group corresponding to the received GroupCallConfig message; the flow is ended.
Step 203, when the second timer times out, if the GroupCallConfig message is not received, the suspended GAP measurement is used to continue the measurement.
Based on the same inventive concept, the embodiment of the present application further provides a TCCH scheduling apparatus based on B-TrunC, which is applied to a base station.

Preferably, the first and second liquid crystal films are made of a polymer,
the timing duration of the first timer is as follows: t1 ═ mod (N × T2, T3); wherein, T1 is the timing duration of the first timer, N is the number of times of sending the sounding message currently, and T3 is the GAP period.
In addition, the embodiment of the application also provides a TCCH scheduling device based on the B-Trunc, which is applied to the User Equipment (UE). Referring to fig. 4, fig. 4 is a schematic structural diagram of a B-TrunC based TCCH scheduling apparatus applied to a UE in the embodiment of the present application. The device includes: a receiving unit 401, a determining unit 402, a timing unit 403, and a processing unit 404;
a receiving unit 401, configured to receive a GroupCallConfig message;
a determination unit 402 configured to determine whether GAP measurement has been started; whether the receiving unit 401 receives a TrunkingPaging message; whether the group carried in the received trunk Paging message is a user signed group or not;
a timing unit 403, configured to start a second timer when the determining unit 402 determines that the UE has started GAP measurement, and receives a traversing Paging message, where a group carried in the traversing Paging message is a user subscription group;
a processing unit 404, further configured to suspend the current GAP measurement when the timing unit 403 starts the second timer; before the second timer times out, if the receiving unit 401 receives a GroupCallConfig message, the second timer is stopped, and the different frequency measurement GAP of the group corresponding to the received GroupCallConfig message is used to perform GAP measurement; when the second timer times out, if the receiving unit 401 does not receive the GroupCallConfig message, the measurement is continued using the suspended GAP measurement.
Preferably, the timing duration of the second timer is greater than one group paging cycle.
Preferably, the first and second liquid crystal films are made of a polymer,
the initiated GAP measurements are either ongoing unicast GAP measurements, or are listening for ongoing GAP measurements by other groups of UEs.
The units of the above embodiments may be integrated into one body, or may be separately deployed; may be combined into one unit or further divided into a plurality of sub-units.
In summary, the application sets a timer at the terminal or the base station side to suspend GAP measurement, so as to receive the groucallconfig message and monitor related group services. The method can avoid TCCH scheduling from falling into a unicast GAP period.
When the pilot frequency networking is carried out, the group signaling avoids the GAP period, and the group users can be ensured to normally receive the group signaling to monitor the group service.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
