Description

Method and equipment for enabling measurement gap parameters to take effect in broadband trunking communication
Technical Field
The present application relates to the field of trunking communications technologies, and in particular, to a method and a device for enabling a measurement gap parameter to take effect in broadband trunking communications.
Background
Inter-frequency measurement (inter-frequency measurement) means that a cell where a terminal is currently located and a target cell are not on one carrier frequency point. If the terminal needs to perform pilot frequency measurement, the terminal needs to switch between the frequency points of the current cell and the target cell. GAP is a measurement GAP (measurement GAP) under the measurement of different frequencies, in the time corresponding to GAP, the terminal can not send and receive any data, and the receiver is adjusted to the frequency point of the target cell to measure different frequencies, and then the current cell is switched to when the GAP time is over.
In the broadband trunking communication (B-TrunC) TS 02.004 protocol, it is described that the group GAP configuration parameters (i.e. the group pilot frequency measurement GAP configuration parameters) are set in the group call configuration (GroupCallConfig) message by IE: the group pilot measurement GAP configuration (groupMeasGapConfig) informs the terminal. The specific protocol is described as follows:
when a group call is established, if a GroupCallConfig IE is configured in a GroupCallConfig message, all terminals receiving the group call ignore measGapConfig IE (configured with the inter-frequency measurement GAP parameter of the point-to-point data service) in the measurement configuration (MeasConfig) IE in the RRC connection reconfiguration (RRCConnectionReconfiguration) message.
When the eNodeB receives G-RNTI R2 MAC CE of the UE, the eNodeB ignores measGapConfig IE in MeasConfig IE in the MeasConfig message in RRCConnectionReconfiguration message, and enables the group pilot frequency measurement GAP parameter configured in the groupMeasGapConfig IE.
When the group call is released, the group pilot frequency measurement GAP of the group call is also released. If the UE ignores the inter-frequency measurement GAP parameter of the point-to-point data service configured in the RRCConnectionReconfiguration message when receiving the group call, when the UE receives a group call release (GroupCallRelease) message, recovering the inter-frequency measurement GAP parameter of the point-to-point data service; after the eNodeB sends the GroupCallRelease message, the eNodeB recovers the pilot frequency measurement GAP parameters of the point-to-point data service configured by RRC reconfiguration for all the group calling UE in the RRC connection state.
According to the protocol description, when a terminal with blind detection capability type 2 receives a trunking Paging (Trunk Paging) message and a GroupCallConfig, G-RNTI R2 MAC CE needs to be reported to join a group, and the contents reported in the two messages are completely consistent, but the reporting roles of the MAC CE in the two messages are different.
Actually, according to the specification of the above protocol, the G-RNTI R2 MAC CE reported after receiving the groupmaasgapcfig IE in the GroupCallConfig message is the signal for taking effect on the group pilot frequency measurement GAP parameter. However, due to the unreliability of MAC CE transmission over the air interface, it cannot be guaranteed that each MAC CE can be received by BBU, and if the MAC CE that just takes effect on the group pilot frequency measurement GAP parameter is not received, the base station side cannot take effect on the group pilot frequency measurement GAP parameter configuration, which may cause the problem of GAP misalignment between the base station and the terminal side, and further cause packet loss or call drop.
In order to solve the above technical problem, it is necessary to ensure the reliability of the transmission of the MAC CE over the air interface, and the reliability of the transmission of the MAC CE over the air interface may need to change a terminal software protocol architecture.
In addition to the above problems, in the inter-frequency group network, when a group call is established, if the terminal happens to be in the peer-to-peer inter-frequency GAP measurement period when the GroupCallConfig message is issued, the terminal cannot receive the GroupCallConfig message in time, which may result in that the terminal cannot receive the source cell data during the inter-frequency GAP measurement period.

In addition, according to the prior art, after receiving the trunking paging message and the group call configuration message, the terminal with blind detection capability type 2 reports twice G-RNTI R2 MAC CEs, which need to be successfully received by the base station, otherwise, the configuration of the group pilot frequency measurement GAP parameters cannot be valid on the base station side, and further, the problem of GAP misalignment between the base station and the terminal side is caused, and packet loss or call drop is generated.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.
In order to solve the problems in the prior art, the present application provides a method for validating measurement gap parameters in broadband trunking communication, which comprises the following steps:
when receiving a group calling page, the connection state monitoring terminal starts a protection timer;
before the protection timer is overtime, the connected state monitoring terminal does not start pilot frequency measurement based on a point-to-point measurement GAP;
after the base station sends a group foreign frequency measurement GAP parameter carrying group foreign frequency Config message, the group foreign frequency measurement GAP parameter is taken into effect for the connection state monitoring terminal in the group;
and after receiving the group pilot frequency measurement GAP parameter in the group pilot Config message, the connected state monitoring terminal sends G-RNTI R2 MAC CE to the base station and generates the group pilot frequency measurement GAP parameter.
The connection state monitoring terminal for starting the protection timer may include: a blind detection capability type 1 connection state monitoring terminal and a blind detection capability type 2 connection state monitoring terminal. For the connected state monitoring terminal with the blind detection capability type 2, in addition to starting the protection timer, the G-RNTI R2 MAC CE needs to be sent to the base station according to the prior art.
The duration of the protection timer may be fixedly set by the terminal or notified to the terminal by the base station.
According to the technical scheme, the protection timer is set, before the protection timer is overtime, the connected state monitoring terminal does not start pilot frequency measurement based on point-to-point measurement GAP, so that the problem that the GroupCallConfig message cannot be received due to the fact that the terminal starts the point-to-point GAP is avoided, the problem that the GroupCallConfig message cannot be received timely due to the fact that the terminal starts the point-to-point GAP is avoided, and access delay is reduced.
In addition, according to the prior art, after receiving the trunking paging message and the group call configuration message, the terminal with blind detection capability type 2 reports twice G-RNTI R2 MAC CEs, which need to be successfully received by the base station, otherwise, the configuration of the group pilot frequency measurement GAP parameters cannot be valid on the base station side, and further, the problem of GAP misalignment between the base station and the terminal side is caused, and packet loss or call drop is generated. By adopting the technical scheme provided by the application, on the base station side, after the base station sends the group pilot frequency measurement GAP parameter carrying group pilot frequency measurement GroupCallConfig message, the group pilot frequency measurement GAP parameter can be taken into effect by the connection state monitoring terminal in the group; on the terminal side, after receiving the group pilot frequency measurement GAP parameters in the group pilot config message, the connection state monitoring terminal sends a G-RNTI R2 MAC CE to the base station, so that the group pilot frequency measurement GAP parameters can be validated, and thus, the group pilot frequency measurement GAP parameters can be validated only by one successful sending in two G-RNTI R2 MAC CEs sent by the terminal, which is equivalent to improving the reliability of the overall scheme.
Based on the above method, the technical solution of the present application is further described in detail by a preferred embodiment with reference to the accompanying drawings.
Referring to fig. 1, when a group call is established, the embodiment performs validation processing on a group pilot frequency measurement GAP parameter according to the following method:
step 1: the group resource establishment procedure is performed between enodebs eCN.
Step 2: the eNodeB sends a group call paging (TrunkingPaging) message to the terminal.
When receiving a group call page, the connected state monitoring terminal starts a protection timer to prohibit the connected state monitoring terminal from starting pilot frequency measurement based on a point-to-point GAP, as shown in a point a in the figure. Wherein, the point a can be set after step 2 or after step 3 in the figure.
And step 3: the terminal transmits G-RNTI R2 MAC CE to the base station.
For the connected state monitoring terminal of the blind test capability type 2, when receiving a group call paging, the connected state monitoring terminal needs to send G-RNTI R2 MAC CE to the base station, according to the scheme of the application, at the same time, a protection timer is started, and during the starting period of the protection timer, the connected state monitoring terminal of the blind test capability type 2 is prohibited from starting pilot frequency measurement based on a point-to-point GAP. Here, the timer duration may be fixedly set by the terminal or notified to the terminal by the base station through a UU message.
For the connected state monitoring terminal of the blind test capability type 1, when receiving the group calling paging, the G-RNTI R2 MAC CE does not need to be sent to the base station, therefore, the step 3 does not need to be executed, but a protection timer is directly started, and the connected state monitoring terminal of the blind test capability type 1 is forbidden to start the pilot frequency measurement based on the point-to-point GAP during the starting period of the protection timer. Similarly, the duration of the timer may be fixedly set by the terminal or notified to the terminal by the base station through a UU message.
And 4, step 4: the base station sends group CallConfig carrying the GAP parameter of the different frequency measurement of group to the terminal station in the group calling.
Thereafter, the base station monitors the connected state in the group, and the user takes effect according to the GAP measurement parameter of the group pilot frequency, as shown in point B in the figure. Point B may be set after step 4 or after step 5 in the figure.
And 5: after receiving the group pilot frequency measurement GAP parameters in the group pilot Config, the terminal sends G-RNTI R2 MAC CE to the base station, and then the GAP configuration parameters can be effective according to the group pilot frequency measurement GAP.
Step 6 and step 7 are to perform group GAP validation processing on the UE side and the base station side, respectively.
This concludes the flow shown in fig. 1.
Corresponding to the above method, the present application discloses a terminal device, whose composition structure is shown in fig. 2, including: a first communication module and a first processing module, wherein:
the first communication module is used for sending and receiving messages;
the first processing module is configured to start a protection timer when the first communication module receives a group call paging from a base station and the terminal device is a connected monitoring terminal; before the protection timer is overtime, the terminal equipment is controlled not to start pilot frequency measurement based on a point-to-point measurement GAP (GAP);

Wherein the types of the terminal equipment comprise: a blind detection capability type 1 connection state monitoring terminal and a blind detection capability type 2 connection state monitoring terminal.
