Description
Technical Field
The present invention relates to the field of trunking group calling technology, and in particular, to a method and an apparatus for monitoring a mobile station in a cell to receive trunking group calling service.
Background
Currently, a Long Term Evolution (LTE) system is mainly applicable to point-to-point communication, that is, one user communicates with another user through a network. However, in practical scenarios, a certain user needs to communicate with multiple users at the same time, for example, when a fire fighter is fighting a fire, a commander needs to send instructions or transmit information to all fire fighters participating in fire fighting at the same time, but the instructions and information are specific to a specific group of people and do not need to be sent to unrelated people, and in some scenarios, the instructions and information may need to be kept secret.
To support such a function, an LTE broadband cluster (B-TrunC) industry alliance has been established, which is mainly responsible for standards establishment and industry development planning of broadband clusters. The LTE broadband cluster supports broadband data, voice cluster, multimedia cluster scheduling and other services, is mainly applied to the fields of government affairs, public safety, key industries and the like, and has important significance for the information development of currently-constructed service governments and industries. The LTE broadband cluster (B-TrunC) technical standard established in china introduces functions such as cluster registration and group calling, and can realize that a certain user sends voice and data to other users in a group at the same time. Each mobile station can know to which group or groups it belongs. Since the mobile stations may be mobile, the mobile stations within the same group may be distributed over different cells of different base stations.
In the existing trunking group call communication, the network will allocate downlink shared resources for transmitting group call voice or video data in all cells of the base station where the mobile station is located. Since the mobile station does not need to feed back any information to the base station, the base station cannot know whether the mobile station is receiving the trunking group call service. At this time, a certain scenario may occur, and although no mobile station receives the group call service in a certain cell, the base station still transmits group call downlink data in these cells, resulting in waste of wireless resources. If each mobile station participating in the group call separately accesses the network through the random access method to respond to the base station that the group call is being received, a signaling storm may be generated instantaneously, which may cause network overload. For this problem (i.e. the problem of improving the group call transmission efficiency), there is no corresponding solution in the prior art.

Detailed Description
As described in the background art, in the existing trunking group call communication, the mobile station does not need to feed back information to the base station, so the base station cannot know whether the mobile station in the cell under the control of the base station is receiving the trunking group call service, which results in a situation that no mobile station receives the trunking group call service in a certain cell, but the base station still transmits group call downlink data in the cell, and a lot of waste of air interface wireless resources is caused.
In order to solve the above problem, embodiments of the present invention provide a method and an apparatus for monitoring a mobile station in a cell receiving a group call service.
At the base station side, the configuration information of the dedicated group call response uplink shared channel is added in the trunking paging message or the group call establishment indication message, so that the mobile station can configure the dedicated group call response uplink shared channel according to the configuration information. The base station will monitor whether there is feedback signal sent by the mobile station on the dedicated group call response uplink shared channel in time, and under the condition that there is feedback signal on the channel (or there is feedback signal monitored in multiple monitoring), downlink transmission resource of group call data is allocated in the cell. In the trunking paging message or group call establishment indication message, the dedicated group call response uplink shared channel is configured independently for different group calls.
And at the mobile station side, the mobile station receives the trunking paging message or the group call establishment indication message sent by the base station, and configures the dedicated group call response uplink shared channel according to the configuration information of the dedicated group call response uplink shared channel in the trunking paging message or the group call establishment indication message. When the mobile station is about to receive or is receiving the trunking group call, the mobile station sends a feedback signal to the base station on a dedicated group call response uplink shared channel corresponding to the group call, so that the base station can know whether the mobile station receives the trunking group call service in the current cell in time.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Example one
The method for monitoring the cluster group call service received by the mobile station in the cell described in this embodiment is applied to the base station.
Fig. 1 is a flowchart illustrating a method for monitoring a mobile station in a cell receiving a group call service according to an embodiment of the present invention.
Referring to fig. 1, the method includes the steps of:
step S11: sending a trunking paging message or a group call establishment indication message to a mobile station in a cell to establish a trunking group call, wherein the trunking paging message or the group call establishment indication message comprises configuration information of a dedicated group call response uplink shared channel, so that the mobile station configures the dedicated group call response uplink shared channel to send a feedback signal to a base station;
step S12: monitoring whether a feedback signal sent by a mobile station exists on the dedicated group call response uplink shared channel;
step S13: if the dedicated group call corresponding to a cluster group call has feedback signal on the uplink shared channel, then the downlink transmission resource of the cluster group call data is allocated in the cell.
Step S14: if the dedicated group call responds to the uplink shared channel without a feedback signal, downlink transmission resources of the group call data are not allocated in the cell.
Specifically, in step S11, after the base station receives the group call request from the mobile station initiating the group call service, it needs to initiate paging of the group call in some cells after communicating with the core network, and it is assumed that all cells in the base station will issue pages to the group call (i.e. paging phase of the trunking group call). The base station informs the mobile station in the cell to receive the GROUP CALL by sending Trunking Paging (Trunking Paging), wherein the Trunking Paging comprises a GROUP identifier corresponding to the GROUP CALL, and the Trunking Paging may further comprise a GROUP CALL SETUP INDICATION (GROUP CALL SETUP INDICATION) message, and the GROUP CALL SETUP INDICATION message is a non-access stratum message.
In order to make the base station know whether there is a mobile station receiving the GROUP CALL, in this embodiment, it is necessary to add a cell in the Trunking Paging (Trunking Paging) message or the GROUP CALL SETUP INDICATION (GROUP CALL SETUP INDICATION) message, where the cell is used to indicate configuration information of the dedicated GROUP CALL response uplink shared channel, and the configuration information is used for the mobile station to configure the dedicated GROUP CALL response uplink shared channel. And the base station indicates the occupied time-frequency resource of the channel through the configuration information. In a trunking paging message, it may contain paging of multiple group calls, and the base station configures configuration information of dedicated group call response uplink shared channel corresponding to a group call independently for different group calls.
Specifically, the configuration information of the dedicated group call response uplink shared channel at least includes: the special group call response uplink shared channel comprises subframe information of the special group call response uplink shared channel, frequency domain information of the special group call response uplink shared channel and power configuration parameters of the special group call response uplink shared channel. The power configuration parameters of the dedicated group call response uplink shared channel may include initial transmission power and a path loss adjustment factor.
In practical application, the configuration information of the dedicated group call response uplink shared channel may further include timeslot information of the dedicated group call response uplink shared channel, a signal format of the dedicated group call response uplink shared channel, and a Time Advance (TA) for the mobile station to send feedback on the dedicated group call response uplink shared channel.
In step S12, the base station will monitor whether there is a feedback signal sent by the mobile station on the dedicated group call response uplink shared channel.
Specifically, after the base station sends out paging for the group call in the cell under its jurisdiction, the base station will also monitor whether there is a feedback signal sent by the mobile station on the dedicated group call response uplink shared channel. In practical application, one base station generally manages a plurality of cells, and the base station can monitor dedicated group call response uplink shared channels in all cells managed by the base station according to related requirements. For example, the base station may monitor the dedicated group call response uplink shared channels in all cells in time, or may monitor the dedicated group call response uplink shared channels in all cells based on a period in which the mobile station sends the feedback signal (the base station may set in the configuration information of the dedicated group call response uplink shared channel, and the subframe information of the dedicated group call response uplink shared channel may include the period information).
As described in steps S13 and S14, if there is a feedback signal on the dedicated group call response uplink shared channel corresponding to a certain group call, downlink transmission resources of group call data corresponding to the group call are allocated in the cell. If the dedicated group call responds to the uplink shared channel without a feedback signal, downlink transmission resources of the group call data are not allocated in the cell.
Specifically, if the base station monitors that there is a feedback signal sent by the mobile station through the dedicated group call response uplink shared channel (i.e., the dedicated group call response uplink shared channel corresponding to a certain trunking group call) in a certain cell, it is considered that there is a mobile station in the cell receiving or about to receive the trunking group call service, and the base station allocates downlink transmission resources of the trunking group call data in the cell for transmitting voice or video data of the trunking group call. On the contrary, if the base station monitors that there is no feedback signal sent by the mobile station through the dedicated group call response uplink shared channel (i.e. the dedicated group call response uplink shared channel corresponding to a certain trunking group call) in a certain cell, it is considered that there is no mobile station in the cell receiving or about to receive the trunking group call service, and the base station will not allocate the downlink transmission resource of the trunking group call data in the cell, so that a large amount of air interface resources can be saved.
Further, after the trunking group call is established, since the mobile station may move, the mobile station currently located in a cell governed by the base station may move to another cell governed by the base station (or a cell governed by another base station) after a period of time.
Based on the above problem, the inventor further considers that after the mobile station in the cell has established the trunking group call, the base station will continuously monitor whether there is a feedback signal sent by the mobile station on the dedicated group call response uplink shared channel, so as to determine whether to reclaim (or continue to allocate) the downlink transmission resource occupied by the cell for processing the trunking group call.
Fig. 2 is a flowchart illustrating a method for monitoring a mobile station receiving a group call service in a cell according to another embodiment of the present invention, where the method is used in a base station.
Referring to fig. 2, the method includes the steps of:
step S15: and the base station continuously monitors whether the dedicated group call response uplink shared channel has a feedback signal sent by the mobile station or not, and records the monitoring times of no feedback signal.
Step S16: and if no feedback signal exists on the dedicated group call response uplink shared channel and the monitoring times of the non-feedback signal are greater than or equal to a preset threshold, no downlink transmission resource of the group call data is allocated in the cell.
Step S17: if there is no feedback signal on the dedicated group call response uplink shared channel, but the monitoring times without feedback signal is less than the predetermined threshold, continuously monitoring whether there is feedback signal sent by the mobile station on the dedicated group call response uplink shared channel, and the base station still continuously allocating downlink transmission resource of the cluster group call data.
Because the feedback period of the mobile station sending the feedback signal on the dedicated group call response uplink shared channel needs to be considered, the base station does not receive the feedback signal sent by the mobile station in an omission way. Therefore, in this embodiment, a monitoring counter may be set on the base station side to record the number of monitoring times for monitoring no feedback signal in a certain cell, and when the number of monitoring times for monitoring no feedback signal recorded by the monitoring counter is greater than or equal to a predetermined threshold, the base station considers that no mobile station in the cell is receiving trunking group call service.
For example, after the mobile station in the cell has established the trunking group call (i.e. while the trunking group call service is in progress), the base station may continue to monitor the dedicated group call response uplink shared channel by using the following specific example.
Step 1.1: resetting the monitoring counter;
step 1.2: monitoring whether a feedback signal sent by a mobile station exists on the dedicated group call response uplink shared channel in a certain cell;
step 1.3: if the judgment result in the step 1.2 is negative, executing a step 1.4; if the judgment result of the step 1.2 is yes, continuing to execute the step 1.1;
step 1.4: adding 1 to the count of the monitoring counter, and determining whether the monitoring times of the non-feedback signals recorded by the monitoring counter is greater than or equal to a preset threshold;
step 1.5: if the judgment result in the step 1.4 is yes, executing a step 1.6; if the judgment result in the step 1.4 is negative, continuing to execute the step 1.2;
step 1.6: the base station does not allocate downlink transmission resources of the trunking group call data in the cell.
It should be noted that, in the above specific example, the predetermined threshold may be set according to actual needs. Preferably, the predetermined threshold is an integer greater than 2.
Based on the method for monitoring the cluster group call service received by the mobile station in the cell, the embodiment also provides a device for monitoring the cluster group call service received by the mobile station in the cell.

The device 1 further comprises a monitoring counter (not shown in the figure) for recording the monitoring times of the base station for monitoring the uplink shared channel of the dedicated group call response without the feedback signal.
The channel monitoring unit 12 is further configured to continuously monitor whether there is a feedback signal sent by the mobile station on the dedicated group call response uplink shared channel, and record the monitoring times without the feedback signal through the monitoring counter.
The transmission resource allocation unit 13 is further configured to not allocate downlink transmission resources of trunking group call data in the cell if the channel monitoring unit 12 does not monitor that there is a feedback signal on the dedicated group call response uplink shared channel, and the monitoring times of the non-feedback signal recorded by the monitoring counter is greater than or equal to a predetermined threshold.
The channel monitoring unit 12 is further configured to, when the channel monitoring unit does not monitor that the dedicated group call response uplink shared channel has a feedback signal, but the monitoring times of the non-feedback signal recorded by the monitoring counter is less than the predetermined threshold, continue to monitor whether the dedicated group call response uplink shared channel has a feedback signal sent by the mobile station, and at this time, continue to allocate downlink transmission resources of the group call data.

Fig. 4 is a flowchart illustrating a method for monitoring a cluster group call service received by a mobile station in a cell according to an embodiment of the present invention.
Referring to fig. 4, the method includes the steps of:
step S21: receiving a trunking paging message or a group call establishment indication message sent by a base station to establish a trunking group call, wherein the trunking paging message or the group call establishment indication message comprises configuration information of a dedicated group call response uplink shared channel;
step S22: configuring the dedicated group call response uplink shared channel according to the configuration information;
step S23: and when the mobile station is about to receive or is receiving the trunking paging message or the trunking group call contained in the group call establishment indication message, the mobile station sends a feedback signal to the base station on a dedicated group call response uplink shared channel corresponding to the trunking group call.
Step S24: after the mobile station has established the trunking group call, continuously sending a feedback signal to the base station on the dedicated group call response uplink shared channel to confirm that the mobile station is still receiving the trunking group call service.
According to the method for monitoring the mobile station receiving the GROUP CALL service in the cell at the base station side provided in the first embodiment, in the Paging phase of the GROUP CALL, a GROUP Paging (Paging) message or a GROUP CALL SETUP INDICATION (GROUP CALL SETUP INDICATION) message sent by the base station includes configuration information of a dedicated GROUP CALL response uplink shared channel. In the trunking paging message or group call establishment indication message, the dedicated group call response uplink shared channel is configured independently for different group calls. Correspondingly, after receiving the trunking paging message or the group call establishment indication message, the mobile station in the cell under the jurisdiction of the base station configures the dedicated group call response uplink shared channel according to the configuration information of the dedicated group call response uplink shared channel therein.
The specific content of the configuration information of the dedicated group call response uplink shared channel may refer to the description in the first embodiment, and is not described herein again.
If the mobile station is about to receive or is receiving the trunking paging message or the trunking group call contained in the group call establishment indication message, the mobile station sends a feedback signal on a dedicated group call response uplink shared channel corresponding to the trunking group call.
Further, after the mobile station has established the trunking group call (i.e. while the trunking group call service is in progress), the mobile station will continue to send a feedback signal to the base station on the dedicated group call response uplink shared channel to confirm that it is still receiving the trunking group call service.
In practical applications, the mobile station may send a feedback signal on the dedicated group call response uplink shared channel according to a set feedback period. The feedback period may be set by the base station in the configuration information of the dedicated group call response uplink shared channel, and is not described herein again.
Based on the method for monitoring the cluster group call service received by the mobile station in the cell, the embodiment also provides a device for monitoring the cluster group call service received by the mobile station in the cell.
Fig. 5 is a schematic structural diagram of an apparatus for a mobile station to monitor the group call service received by a mobile station in a cell according to the present invention.
Referring to fig. 5, the apparatus 2 for monitoring the mobile station receiving the group call service in the cell includes:
the message receiving unit 21 is configured to receive a trunking paging message or a group call setup indication message sent by a base station to set up a trunking group call, where the trunking paging message or the group call setup indication message includes configuration information of a dedicated group call response uplink shared channel.

The signal sending unit 23 is further configured to continue to send a feedback signal to the base station on the dedicated group call response uplink shared channel after the mobile station has established the group call, so as to confirm that it is still receiving the group call service.
In summary, the technical solution solves the problem of wasting a lot of air interface resources in the existing trunking group call communication, because the base station cannot determine whether the mobile station in the cell is receiving the trunking group call service, so that when no mobile station in the cell receives the trunking group call service, the base station still transmits trunking group call data in the cell.
