Description

Group access control method, device, equipment and computer readable storage medium
Technical Field
Embodiments of the present disclosure relate to the field of wireless communications technologies, and in particular, to a group access control method, apparatus, device, and computer-readable storage medium.
Background
Two group types of a Multicast group and a unicast group are defined in a 3rd Generation Partnership Project (3 GPP) Push to Talk (MCPTT) key task protocol, when an air interface adopts a Multicast Single Frequency Network (MBSFN) mode for transmission, a Multicast group service is carried on a Multicast subframe, and a unicast group service is carried on a unicast subframe. After the Modulation and Coding Scheme (MCS) of the multicast Traffic multicast Channel (MBSFN Traffic Channel, MTCH) is determined, the number of multicast groups that can be supported by each Service Area (SA) is limited.
In the prior art, generally, a multicast resource exists, a multicast group is accessed according to a multicast mode, when the upper limit of the supportable multicast group is reached, users in the multicast group are accessed according to a unicast mode, and at this time, the resources of unicast subframes are occupied.
When the multicast groups are simultaneously transmitted more, more multicast resources can be occupied, and due to the difference of the number of users of the multicast groups, if the multicast groups with less users are still accessed according to the multicast mode, the group with more subsequent users can not acquire the multicast resources and can only access unicast subframes, and in extreme cases, a certain cell can be congested and users can not log in. In addition, if the multicast group is accessed in a unicast manner, the corresponding monitoring users need to be notified through the paging message, but because the paging cycle of the current pipeline side is long and some monitoring users may be in a dormant state, the problems of delay, word loss and the like during group establishment can be caused, and the user perception of the high-priority group is seriously influenced.
Disclosure of Invention
In order to solve the problems in the prior art, the present application provides a group access control method, apparatus, device and computer readable storage medium.
In order to achieve the above object, the embodiments of the present invention provide the following technical solutions:
in a first aspect, an embodiment of the present application provides a group access control method, including the following steps: when a target group accesses a service area, determining the number of occupied multicast resources in the service area, where the target group may be determined according to an actual situation, and the embodiment of the present application does not particularly limit this. Similarly, the service area may be determined according to actual conditions, and the number of multicast groups that can be supported by the service area is limited. When a target group accesses a service area, firstly, the occupied number of multicast resources in the service area is determined. And if the occupied number of the multicast resources in the service area reaches a first preset occupied threshold value, accessing the target group into the service area according to the priority of the target group, wherein the priority of the target group is determined according to the number of online users of the target group, for example, the number of online users of the target group is large, the priority of the target group is high, the number of online users of the target group is small, and the priority of the target group is low. The first preset occupation threshold is a threshold of the number of occupied multicast resources in the service area, and may be determined according to actual conditions. Here, if the number of occupied multicast resources in the service area reaches a first preset occupation threshold, which indicates that the number of the occupied multicast resources in the service area is limited, it is necessary to prioritize a group, that is, access the group to the service area based on the priority of the group. And if the occupation number of the multicast resources in the service area reaches a second preset occupation threshold value, and the second preset occupation threshold value is larger than the first preset occupation threshold value, preempting the multicast resources in the service area according to the priority of the target group, and accessing the target group into the service area according to the preempted multicast resources. Wherein the second predetermined occupation threshold is an upper limit of the number of multicast resources in the service area, and the value may vary for each MCS. If the number of occupied multicast resources in the service area reaches a second preset occupation threshold, it indicates that the current multicast resources in the service area are fully used, at this time, the multicast resources need to be preempted according to the group priority, and then the group is accessed to the service area according to the preempted multicast resources.
Here, in the embodiment of the present application, when the multicast resource occupancy of the service area reaches a certain threshold but does not reach an upper limit, the service area is accessed based on the priority of the group, and when the multicast resource occupancy of the service area reaches the upper limit, the multicast resource is preempted according to the priority of the group, and then the group is accessed to the service area according to the preempted multicast resource, where the priority of the group is determined according to the number of online users of the group, for example, the number of online users of the group is multiple and has a high priority, so that a high-priority group is accessed according to a multicast mode, it is ensured that the group with the large number of users can obtain the multicast resource, the situations that a cell is congested and a user cannot log in are avoided, and the user perception of the high-priority group is improved.
In one possible implementation manner, the accessing the target group to the service area according to the priority of the target group includes:
and if the priority of the target group is greater than a preset priority threshold, accessing the target group to the service area in a multicast mode.
The preset priority threshold is a judgment threshold of the low priority group, and may be specifically set according to an actual situation, which is not particularly limited in the embodiment of the present application. If the group priority is less than or equal to the preset priority threshold, the group is a low priority group; otherwise, it is a high priority group. Here, if the priority of the target group is greater than a preset priority threshold, which indicates that the target group is a high priority group, the target group is accessed to the service area in a multicast manner, so that the high priority group is accessed in the multicast manner, and application requirements are met.

and if the number of the online users is smaller than or equal to the preset user number threshold, accessing the target group to the service area in a unicast mode.
Here, if the group priority is less than or equal to the preset priority threshold, the group is a low-priority group, and in order to enable a group with a large number of users in the low-priority group to acquire multicast resources, the preset user number threshold is set in the embodiment of the present application, and the preset user number threshold is a threshold for determining how many users are, which may be specifically set according to an actual situation, and is not particularly limited in the embodiment of the present application. If the number of users is smaller than or equal to a preset user number threshold value, the group with more users is formed; otherwise, the group is a group with few users. If the number of the online users of the target group is larger than the preset user number threshold value, it is indicated that the number of the online users of the target group is large, the online users of the target group are accessed into a service area in a multicast mode, otherwise, the online users of the target group are accessed into the service area in a unicast mode, the group with the large number of users can be ensured to obtain multicast resources, and the method is suitable for application.
In a possible implementation manner, the preempting multicast resources in the service area according to the priority of the target group includes:

If the number of users in the plurality of groups is the same, the released group multicast resources can be randomly selected.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "first," "second," "third," and "fourth," if any, in the description and claims of this application and the above-described figures are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In the related technology, two group types of a multicast group and a unicast group are defined in a 3GPP MCPTT protocol, when an air interface adopts an MBSFN mode for transmission, multicast group service is borne on a multicast subframe, and unicast group service is borne on a unicast subframe. After the MCS of the multicast traffic MTCH is determined, the number of multicast groups supportable per Service Area (SA) is limited.
When the multicast groups are simultaneously transmitted more, more multicast resources can be occupied, and due to the difference of the number of users of the multicast groups, if the multicast groups with less users are still accessed according to the multicast mode, the group with more subsequent users can not acquire the multicast resources and can only access unicast subframes, and in extreme cases, a certain cell can be congested and users can not log in. In addition, if the multicast group is accessed in a unicast manner, the corresponding monitoring users need to be notified through the paging message, but because the paging cycle of the current pipeline side is long and some monitoring users may be in a dormant state, the problems of delay, word loss and the like during group establishment can be caused, and the user perception of the high-priority group is seriously influenced.
Therefore, in view of the above problems, the present application provides a group access control method, where when the multicast resource occupancy in a service area reaches a certain threshold but does not reach an upper limit, the group is accessed to the service area based on the priority of the group, and when the multicast resource occupancy in the service area reaches the upper limit, the multicast resource is preempted according to the group priority, and then the group is accessed to the service area according to the preempted multicast resource, where the priority of the group is determined according to the number of online users of the group, for example, the number of online users of the group is multiple and has a high priority, so that a high-priority group is accessed in a multicast manner, it is ensured that the group with the large number of users can obtain the multicast resource, and situations that a cell is congested and a user cannot log in are avoided, and user perception of the high-priority group is improved.
Optionally, the group access control method provided in the embodiment of the present application may be applied to the application scenario shown in fig. 1. Fig. 1 only describes, by way of example, one possible application scenario of the group access control method provided in the embodiment of the present application, and the application scenario of the group access control method provided in the embodiment of the present application is not limited to the application scenario shown in fig. 1.
Fig. 1 is a schematic diagram of a group access control system architecture. In fig. 1, the architecture is exemplified by a certain service area, and the multicast resources of the service area are limited. The service area is provided with a network device 110, an access control device 120 and a plurality of terminal devices 130, and the plurality of terminal devices 130 access the network device 110 in the service area in a group (two types of group, multicast group and unicast group) through the access control device 120. It is understood that the above-described architecture may include a plurality of network devices and each network device may include other numbers of terminal devices within the coverage area, which is not limited in this application.
The network device 110 may be a device that communicates with the terminal device 130 (or referred to as a communication terminal, terminal). Network device 110 may provide communication coverage for a particular geographic area and may communicate with terminal devices located within that coverage area.
Alternatively, the network device 110 may be a base station, a mobile switching center, a relay station, or the like. The embodiments of the present application do not limit the specific technologies and the specific device forms used by the network devices.
In the embodiment of the present application, the terminal device 130 may be any terminal, for example, the terminal device 130 may be a user equipment for machine type communication. The terminal device 130 may also be referred to as a User Equipment (UE), a Mobile Station (MS), a mobile terminal (mobile terminal), a terminal (terminal), and so on.
The access control device 120 may control the end device 130 to access the network devices 110 in the service area in both multicast group and unicast group types. For example, the access control device 120 may access the multicast resource to the service area based on the priority of the group in which the terminal device 130 is located when the multicast resource occupancy of the service area reaches a certain threshold but does not reach an upper limit, preempt the multicast resource according to the priority of the group in which the terminal device 130 is located when the multicast resource occupancy of the service area reaches the upper limit, and then access the group to the service area according to the preempted multicast resource.
Alternatively, network device 110, access control device 120, and terminal device 130 may be deployed on land, including indoors or outdoors, hand-held, or in-vehicle; can also be deployed on the water surface; and may also be deployed on airborne aircraft, balloons, and satellite vehicles, as embodiments of the present application are not particularly limited in this regard.
It should be understood that the system architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation to the technical solution provided in the embodiment of the present application, and as a person having ordinary skill in the art knows that along with the evolution of the system architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart illustrating a group access control method according to an embodiment of the present application, where an execution subject according to the embodiment of the present application may be the access control device 120 in the embodiment of fig. 1. As shown in fig. 2, the method may include:
s201: when the target group accesses the service area, determining the occupied number of multicast resources in the service area.
The target group may be determined according to actual conditions, and this is not particularly limited in the embodiment of the present application. Similarly, the service area may be determined according to actual conditions, and the number of multicast groups that can be supported by the service area is limited.
When a target group is accessed to a service area, firstly, the occupied number of multicast resources in the service area is determined, so that the target group is accessed to the service area by adopting different access strategies based on the occupied number of the multicast resources.
S202: and if the occupation number of the multicast resources reaches a first preset occupation threshold, accessing the target group to the service area according to the priority of the target group.
The priority of the target group is determined according to the number of online users of the target group. For example, the number of online users of the target group is large, the priority of the target group is high, the number of online users of the target group is small, and the priority of the target group is low.
Here, the first preset occupation threshold is a threshold of the number of occupied multicast resources in the service area, and may be determined according to actual conditions. If the number of occupied multicast resources in the service area reaches a first preset occupation threshold, it indicates that the multicast resources in the service area are limited, and it is necessary to prioritize the group, i.e. access the group to the service area based on the priority of the group.
In this embodiment, if the number of occupied multicast resources does not reach the first preset occupied threshold, which indicates that the multicast resources in the service area are sufficient, the group access may be performed in a multicast manner without differentiating the group priority, that is, the target group is accessed to the service area in a multicast manner.
S203: and if the number of the occupied multicast resources reaches a second preset occupied threshold which is larger than the first preset occupied threshold, preempting the multicast resources in the service area according to the priority of the target group, and accessing the target group to the service area according to the preempted multicast resources.
Wherein the second predetermined occupation threshold is an upper limit of the number of multicast resources in the service area, and the value may vary for each MCS. If the number of occupied multicast resources in the service area reaches a second preset occupation threshold, it indicates that the current multicast resources in the service area are fully used, at this time, the multicast resources need to be preempted according to the group priority, and then the group is accessed to the service area according to the preempted multicast resources.
In a possible implementation manner, after performing multicast resource preemption in the service area according to the priority of the target group, the method further includes:
and if the multicast resource preemption fails, accessing the target group to the service area in a unicast mode.
Illustratively, the accessing the target group to the service area in a unicast manner includes:
judging whether the permission number required by the target group according to the unicast group is larger than the residual voice permission number of the service area;

S306: and if the number of the online users is smaller than or equal to the preset user number threshold, accessing the target group to the service area in a unicast mode.
Here, if the group priority is less than or equal to the preset priority threshold, the group is a low-priority group, and in order to enable a group with a large number of users in the low-priority group to acquire multicast resources, the preset user number threshold is set in the embodiment of the present application, and the preset user number threshold is a threshold for determining how many users are, which may be specifically set according to an actual situation, and is not particularly limited in the embodiment of the present application.

Here, if there are a plurality of groups in the service area having a group priority lower than the target group priority, a group with a small number of users can be selected from the plurality of groups, and multicast resources of the group with the small number of users can be released. For example, the groups may be sorted from a small number to a large number according to the number of users, and the group with the small number of users may be selected from the plurality of groups according to the sorting result, thereby releasing the multicast resources of the group with the small number of users.
If the number of users in the plurality of groups is the same, the released group multicast resources can be randomly selected.
In addition, if there is only one group with a group priority lower than the target group priority in the service area, the multicast resource of the group can be released directly.

S503: if the number of the occupied multicast resources reaches a second preset occupation threshold value, the second preset occupation threshold value is larger than the first preset occupation threshold value, the multicast resources are preempted in the service area according to the priority of the target group, and if the multicast resources are preempted, whether the allowed number required by the target group according to the multicast group establishment is larger than the remaining voice allowed number in the service area is judged.
S504: and if the required permission number is larger than the residual voice permission number in the service area, performing voice permission resource preemption in the service area.

determining the conversation priority of the users who have occupied the voice permission in the service area;
and according to the determined session priority, performing voice permission resource preemption in the service area.
Here, the voice admission resources can be released from the user with the smallest priority in the order of the session priority size. The session priority may be determined according to actual situations, and is not particularly limited in this embodiment of the present application.
Wherein, the voice permission to be preempted is equal to the difference between the required permission number and the remaining voice permission number of the service area, and the preempted voice permission is preferentially used for multicast.
S505: and accessing the target group to the service area in a multicast mode according to the preempted voice permission resource.
In the embodiment of the application, if the multicast resource is preempted, the multicast resource is established according to the multicast group, the allowed number required by the establishment of the target group according to the multicast group is determined, whether the number is greater than the remaining voice allowed number of the service area is judged, that is, whether the current remaining voice allowed number of the service area is enough is judged, if the number is insufficient, the voice allowed resource is preempted in the service area, and further, the target group is accessed to the service area in a multicast mode based on the preempted voice allowed resource, so that the high-priority group is accessed in the multicast mode, and the group with a large number of users can acquire the multicast resource.
The number of the permissions required by the target group according to the establishment of the multicast group is determined according to the number of the 1-path multicast permissions, the number of users which do not meet the multicast conditions in the target group and the number of users which have unicast load in the target group.
For example, the sum of the number of the 1-path multicast grants and the number of users that do not satisfy the multicast condition in the target group is calculated, and then the difference between the sum and the number of users that have unicast bearers in the target group is calculated, and the difference is used as the number of grants required by the target group for establishing the multicast group.
