Abstract

The present invention relates to the technical field of communications. Disclosed are a cluster communication application server, an evolved node base station (eNB), a system, and a resource allocation method, capable of solving the problem that, because of restricted admission control of an eNB caused by each user equipment (UE) being allocated a session resource, the UE cannot engage in cluster communication and cell access of other UE is affected. The method comprises: receiving a floor request transmitted by a UE, where the floor request carries a group ID and a cell ID of where the UE is located; determining, on the basis of a first mapping table, whether or not a session resource is allocated to a session object jointly determined by the group ID of where the UE is located and by the cell ID of where the UE is located, where the first mapping table is used for describing session resource allocation states of each group in each cell; and, if no session resource is allocated to the session object jointly determined by the group ID and the cell ID of where the UE is located, then transmitting to an eNB a resource allocation request. The present invention is primarily applicable in a process of terminal communication.

Description

一种集群通信应用服务器、演进型基站、系统及资源分配的方法技术领域 Method for cluster communication application server, evolved base station, system and resource allocation

本发明涉及通信技术领域，尤其涉及一种集群通信应用服务器、演进型基站、系统及资源分配的方法。背景技术 The present invention relates to the field of communications technologies, and in particular, to a trunking communication application server, an evolved base station, a system, and a method for resource allocation. Background technique

随着通信技术的发展，集群通信（Group Communicat ion, 简称 GC )得到广泛应用。集群通信的一种基本方式为组呼，即在群组内，群组成员 A通过按下 PTT ( Push To Ta lk )按键后即可开始讲话，该群组的其他组群成员都可以听到组群成员 A的话音。 With the development of communication technology, Group Communication (GC) has been widely used. A basic method of trunking communication is group call, that is, in the group, group member A can start speaking by pressing the PTT (Push To Ta lk) button, and other group members of the group can hear The voice of the group member A.

现有技术中通过如下方式为集群通信中的各群组成员分配资源：组群成员 A在发起会话时，向集群通信应用服务器 ( Group Communicat ion Service Enabler Appl i cat ion Server , 简称 GCSE AS ) 发出话语权请求，集群通信应用服务器判断是否已为组群成员 A分配会话资源。如果未为组群成员 A 分配会话资源则向演进型基站 eNB发送资源分配请求，演进型基站根据该资源分配请求为组群成员 A分配会话资源。本发明中所述的会话资源也称为保证比特率（Guaranteed Bi t Rate简称 GBR )承载。集群通信应用服务器为组群成员 A分配会话资源，等同于集群通信应用服务器为组群成员 A分配 GBR 承载。 In the prior art, resources are allocated to each group member in the cluster communication by: the group member A sends a message to the group communication application server (GCSE AS) when initiating the session. The voice right request, the cluster communication application server determines whether the session resource has been allocated to the group member A. If the session resource is not allocated to the group member A, the resource allocation request is sent to the evolved base station eNB, and the evolved base station allocates the session resource to the group member A according to the resource allocation request. The session resource described in the present invention is also referred to as a Guaranteed Bit Rate (GBR) bearer. The cluster communication application server allocates session resources for group member A, which is equivalent to the cluster communication application server assigning GBR bearers to group member A.

在实现上述资源分配的过程中，发明人发现现有技术中至少存在如下问题： In the process of realizing the above resource allocation, the inventors found that at least the following problems exist in the prior art:

由于现有会话资源（GBR承载）是针对每个 UE进行建立的，即一个会话资源 ( GBR承载）只能被一个 UE专用。不同的 UE要发送数据就要建立不同的 GBR 承载。在集群通信中如果一个 GC的成员比较多的集中在一个小区，而每个 UE 均有要发送的数据，则要为 GC中的每个 UE均建立 GBR承载。然而 GBR承载需要预留资源，因此导致大量的会话资源被预留。此时，影响到 eNB 的接纳控制（ca l l admi s s ion control ) ，所谓接纳控制就是指核心网要求 eNB为某个 UE建立 GBR承载时， eNB因没有剩余的会话资源而无法为 UE建立该 GBR承载，所以只能拒绝。比如一个有 GBR承载的 UE在切换过程中被目标侧的小区拒绝可能就是因为该小区已经没有足够的资源为 UE建立 GBR承载。发明内容 Since the existing session resources (GBR bearers) are established for each UE, that is, one session resource (GBR bearer) can only be dedicated to one UE. Different UEs need to establish different GBR bearers to send data. In a cluster communication, if a member of a GC is concentrated in one cell and each UE has data to be transmitted, a GBR bearer is established for each UE in the GC. However, the GBR bearer needs to reserve resources, thus causing a large amount of session resources to be reserved. At this point, affecting the acceptance of the eNB Control (ca ll admi ss ion control), the so-called admission control means that the core network requires the eNB to establish a GBR bearer for a certain UE. The eNB cannot establish the GBR bearer for the UE because there is no remaining session resources, so it can only refuse. For example, a UE with a GBR bearer may be rejected by the target side cell during the handover process because the cell does not have enough resources to establish a GBR bearer for the UE. Summary of the invention

本发明的实施例提供一种集群通信应用服务器、演进型基站、系统及资源分配的方法，能够解决由于每个 UE分配会话资源导致 eNB的接纳控制受限，使 UE无法进行集群通信以及影响其他 UE小区接入的问题。 The embodiments of the present invention provide a cluster communication application server, an evolved base station, a system, and a resource allocation method, which can solve the problem that the admission control of the eNB is limited due to the allocation of session resources by each UE, so that the UE cannot perform cluster communication and affect other The problem of UE cell access.

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。 The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

本发明实施例提供了一种集群通信应用服务器，如图 1 所示，所述集群通信应用服务器包括： The embodiment of the present invention provides a cluster communication application server. As shown in FIG. 1, the cluster communication application server includes:

接收器 1 1 , 用于接收用户设备 UE发送的话语权请求（F l oor Reques t ), 所述话语权请求中携带有所述用户设备所在的小组标识和小区标识。处理器 12 ,用于根据第一映射表判断是否已为所述接收器 1 1接收的所述用户设备所在的小组标识和所述用户设备所在的小区标识共同确定的会话对象分配会话资源，所述第一映射表用于描述各小组在各小区中的会话资源分配情况。 The receiver 1 1 is configured to receive a voice right request (F l oor Reques t ) sent by the user equipment UE, The voice right request carries the group identifier and the cell identifier where the user equipment is located. The processor 12 is configured to determine, according to the first mapping table, whether a session resource is allocated to the session object that is jointly determined by the group identifier of the user equipment and the cell identifier of the user equipment that is received by the receiver 11 The first mapping table is used to describe the allocation of session resources in each cell by each group.

作为一种可选的实施方式，第一映射表如表 1 所示，由小组标识和小区标识共同确定一个会话资源。如果未为小组标识和小区标识共同确定的会话资源分配资源，则对应的资源上标识为 0。如果已为小组标识和小区标识共同确定的会话资源分配资源，则对应的资源上标识为 1。在表 1中，小区 A中已分配会话资源的小组标识为 2和 3 ,小区 B中已分配会话资源的小组标识为 1 , 小区 C中已分配会话资源的小组标识为 3。 As an optional implementation manner, the first mapping table is as shown in Table 1, and a session resource is jointly determined by the group identifier and the cell identifier. If the resource is not allocated for the session resource determined by the group identifier and the cell identifier, the corresponding resource is identified as 0. If a resource has been allocated for the session resource that is jointly determined by the group identifier and the cell identifier, the corresponding resource is identified as 1. In Table 1, the group IDs of the session resources allocated in the cell A are 2 and 3, the group ID of the allocated session resources in the cell B is 1 , and the group ID of the allocated session resources in the cell C is 3.

表 1 Table 1

由于每个小区中的会话资源（GBR承载）位于演进型基站中，且并由演进型基站决定将具体的频段的频谱作为会话资源。因此，当集群通信应用服务器确定需要为某个小区标志和小区标识共同确定的会话对象分配会话资源时，向该小区标识表示的演进型基站发送所述小组标识，以便演进型基站为所述小组标识分配会话资源。 Since the session resource (GBR bearer) in each cell is located in the evolved base station, and the evolved base station decides to use the spectrum of the specific frequency band as the session resource. Therefore, when the cluster communication application server determines that a session resource that needs to be jointly determined for a certain cell identifier and the cell identifier is allocated, the group identifier is sent to the evolved base station indicated by the cell identifier, so that the evolved base station is the group. Identifies the allocation of session resources.

本发明实施例提供的资源分配的方法，能够根据用户设备所在的小组标识和小区标识共同确定的会话对象分配会话资源（GBR承载），如果未为所述用户设备所在的小组标识和小区标识共同确定的会话对象分配会话资源，则向演进型基站 eNB发送资源分配请求。现有技术中为每个 UE建立会话资源。本发明中集群通信应用服务器只为每个小区的每个小组分配一个会话资源 (每个小组在每个小区中分配一个会话资源）。由于集群通讯中，在同一时间点上只允许一个 UE发送数据，因此在每个小区为每个小组分配会话资源后，既可以保证集群通信的正常使用，又可以提高网络中集群通信业务的数量，解决 eNB的接纳控制受限的问题，提高网络资源的利用率。 The method for resource allocation provided by the embodiment of the present invention can be based on the group standard of the user equipment And the session object allocation session resource (GBR bearer) jointly determined by the identifier and the cell identifier, if the session resource is not allocated for the session object jointly determined by the group identifier and the cell identifier of the user equipment, sending a resource allocation request to the evolved base station eNB . In the prior art, session resources are established for each UE. In the present invention, the trunking communication application server allocates only one session resource for each group of each cell (each group allocates one session resource in each cell). In the cluster communication, only one UE is allowed to send data at the same time. Therefore, after each session allocates session resources to each group, the normal use of the cluster communication can be ensured, and the number of cluster communication services in the network can be improved. The problem of limited admission control of the eNB is solved, and the utilization of network resources is improved.

If the session resource is not allocated for the group identity, a resource allocation request is sent to the evolved base station.

同理的，也可先判断是否已为用户设备所在的小区标识分配会话资源。如果已分配，则该小区标识中是否已为用户设备所在的小组分配会话资源，如果已为所述小组标识分配会话资源则由演进型基站根据已分配的会话资源为用户设备提供会话服务。如果未为所述小组标识分配会话资源，则向演进型基站发送资源分配请求。 Similarly, it can be determined whether the session resource has been allocated for the cell identifier where the user equipment is located. If allocated, the session identifier is allocated to the group in which the user equipment is located. If the session resource has been allocated for the group identifier, the evolved base station provides session service for the user equipment according to the allocated session resource. If a session resource is not allocated for the group identity, a resource allocation request is sent to the evolved base station.
