Description

蜂窝通信系统在集群业务中分配无线反向信道的方法 A wireless cellular communication system allocates a reverse channel in the trunking service

技术领域 FIELD

本发明涉及移动通信技术,更确切地说是涉及蜂窝通信系统在集群业务中分配无线反向信道的方法。 The present invention relates to a mobile communication technology, and more specifically relates to a wireless cellular communication system allocates a reverse channel in the trunking service.

背景技术 Background technique

无线信道分为前向信道和反向信道,前向信道是指从基站至无线终端的信道,反向信道则相反,是指无线终端至基站的信道。 Before a radio channel is divided into a forward channel and reverse channel, refers to a forward channel from a base station to wireless terminal channel, a reverse channel on the contrary, it refers to the channel of the radio terminal to the base station. 假设A是基站,B是无线终端,那么A->B方向上的通信走前向信道,B->A方向上的通信走反向信道。 A hypothesis is a base station, B is a wireless terminal, then A- & gt; a communication channel to the front down direction B, B- & gt; down the communication channel in the reverse direction A.

语音组呼业务和语音广播业务是集群通信业务中的两项主要业务,集群业务的典型应用是组呼,其特点是通话在多个组内成员间进行(组内成员可简称组成员)。 Voice group call service and voice communication service broadcast service is a cluster of two main operations, typical applications are the cluster group call service, characterized by an active call (group members may be referred to as group member) among the members of the plurality of groups.

移动通信系统中的语音组呼业务(VGCS:vioce Group Call Service),实现半双工模式的集群呼叫。 Voice Group Call Service in a mobile communication system (VGCS: vioce Group Call Service), the half-duplex mode call for clustering. 通常,集群组内有两类组内成员:一个或多个调度员和一个或多个集群业务用户,调度员必须经过系统授权才能成为调度员。 Generally, there are two types of group members within the cluster group: One or more dispatcher and one or more clusters of business users, dispatchers must be authorized through the system to become a dispatcher. 作为调度员的用户终端可以是任何电话设备,如普通固定电话机或者各种制式的公网手机,但集群业务用户必须是支持集群业务的无线终端。 As a dispatcher user terminal can be any telephone equipment, such as ordinary fixed telephones or mobile phones all modes of public network, but the cluster must be supported by business users of wireless trunking service terminal. 一个集群组内的任一个集群业务用户与任何一个经过授权的调度员均可以发起组呼请求。 Any business user a cluster within a cluster group with any authorized dispatcher can be initiated group call request. 组呼请求发起时,集群组内的所有调度员以及在组呼范围内的集群业务用户都能够接收到组呼发起请求。 When a request to initiate a group call, all dispatchers in the cluster and the cluster group in the group call service user can receive the range request to initiate the group call. 任一个调度员可以随时讲话,但是在同一时间内,只允许一个集群业务用户讲话,他们通过按PTT键取得发言权。 Either a dispatcher can always talk, but at the same time, allows only one user to speak trunking service, they get a say by pressing the PTT key.

语音组呼业务的特点是:各集群业务用户在听的时候,他们所听到的内容都是一样的;在同一时间内只能有一个集群业务用户讲话。 Voice Group Call Service is characterized by: each cluster business users when listening, they heard the contents are the same; at the same time only one cluster business users speak.

集群业务虽然历史悠久,但对作为共网运营的蜂窝通信系统来讲还是个新生事物,因而在其实现技术上也提出了新的挑战。 Although the business cluster has a long history, but as a co-cellular communication system or network operator in terms of a new thing, and therefore technically in its implementation presents new challenges.

目前,蜂窝通信系统是针对每个用户分配、建立一条无线反向信道,来为用户提供服务。 Currently, the cellular communication system is allocated for each user to establish a wireless reverse channel, to provide services for users.

在蜂窝通信系统提供集群业务时,若仍沿用该技术,针对每个集群业务用户分配一条无线反向信道,将会造成无线反向信道的极大浪费,因为在众多的集群业务用户中在同一时间只有一个用户讲话;同时这样做也会给小区容量造成影响。 In the cellular communication system to provide trunking services, if the technology is still in use, assign a wireless backchannel for each cluster business user, will cause great waste of wireless reverse channel, because in many business users in the same cluster only one user speech; doing so will cause impact on cell capacity.

发明内容 SUMMARY

本发明的目的是设计一种蜂窝通信系统在集群业务中分配无线反向信道的方法,和为每个用户建立一条无线反向信道的方法形成互补的效果,通过利用共享无线反向信道为集群业务用户提供服务,达到节省无线反向信道资源的目的。 Object of the present invention is to devise a method for allocating a wireless cellular communication system in a reverse channel in a trunking service, and the establishment of a wireless reverse channel for each user a method of forming a complementary effect, by using the shared reverse channel radio cluster business users provide services to achieve the goal of saving wireless reverse channel resources.

实现本发明目的的技术方案是这样的:一种蜂窝通信系统在集群业务中分配无线反向信道的方法,其特征在于:在语音组呼业务中,基站控制中心为同一小区内的同一集群组的多个无线终端分配一条共享无线反向信道。 Achieve the object of the present invention is a technical solution: A method for allocating a wireless cellular communication system in a reverse channel in a trunking service, comprising: a voice group call service, the base station within the same cell as the control center of the same cluster a plurality of groups of wireless terminals allocated a shared wireless reverse channel.

还包括:基站控制中心接收到语音组呼业务的资源指配请求时,根据请求消息中的服务小区列表,为每个服务小区至多分配一条用于广播消息的前向广播信道。 Further comprising: a base station control center receives the resource of the voice group call service refers to assignment request, the service request message according to the cell in the list, before the allocation of the broadcast channel used to broadcast a message for each serving cell at most.

共享无线反向信道可以是预先分配给各小区的固定的无线反向信道,在同一小区的一集群业务用户申请讲话时,将该固定的无线反向信道提供给该用户使用,该用户讲话完毕后则让出该固定的无线反向信道,供同一小区、同一集群组中的其他申请讲话的用户使用。 Wireless shared reverse channel may be pre-assigned to each cell of a fixed wireless reverse channel, when a service user in the same cell cluster speech applications, the fixed wireless backchannel provided to the user, the user is finished speaking after letting out the fixed wireless reverse channel, for the same cell, the other applications in the same cluster group speech users.

共享无线反向信道还可以是为各小区内申请讲话的一集群业务用户动态分配的无线反向信道,在该用户讲话完毕后即回收该无线反向信道。 Wireless shared reverse channel may also apply for the speech traffic in each cell a cluster dynamically allocated wireless user reverse channel, the reverse recovery of the wireless channel after the user is finished speaking.

本发明的方法,采用共享无线反向信道为集群业务用户提供服务,该共享无线反向信道可以预先分配好,谁申请谁使用;也可以随时申请随时分配。 The method of the present invention, uses a shared reverse channel to provide wireless trunking service user services, which can be shared reverse channel radio preallocated, who applied who use; always apply at any time may be assigned. 由于一个小区内的所有集群业务用户共同享用一条无线反向信道,从而降低了蜂窝通信系统的建设、运营、维护成本;此外通过无线信道共享,还提高了小区容量。 Since all users in a trunking service access to a wireless cell common reverse channel, thereby reducing the construction of a cellular communication system, operation, and maintenance costs; shared wireless channel in addition, further increase the cell capacity.

本发明的方法可应用于码分多址蜂窝移动通信网络中的移动应用技术方案中,但并不局限于此。 The method of the present invention can be applied in a code division multiple access cellular mobile communication network of mobile application programs, but is not limited thereto.

具体实施方式 Detailed ways

根据VGCS业务的特点,在同一时间内各个集群业务用户听到的内容都是一样的,那么在同一小区内就没有必要为每一个用户分配一条前向信道,可以只分配一条前向共享信道供所有用户听;另外,在不同时间内每个业务用户都可以讲话,但是在同一时间内只能有一个用户讲话,那么在同一小区可以只分配一条反向共享信道供该小区的所有集群业务用户共用。 According to the characteristics VGCS business, at the same time each cluster business users hear the contents are the same, then in the same district there is no need to allocate before a forward channel for each user, you can assign only the first one for the shared channel All users listen; in addition, at different times each business user can speak, but at the same time only one user can speak, you can only assign a reverse share all cluster channel for business users of the cell in the same cell share.

在语音组呼业务中,按本发明共享无线反向信道的思想,可以采用两种分配方法来共享反向信道:固定分配共享反向信道和动态分配共享反向信道。 Voice group call service in accordance with the present invention is thought to share the reverse channel radio, two allocation methods may be employed to share the reverse channel: fixed allocation shared reverse channel, and dynamically allocated shared reverse channel.

固定分配共享反向信道,是在同一个小区中为所有的集群组用户预先分配一条固定的反向信道,有用户需要讲话时通过申请,即可将该固定的反向信道提供给该用户使用,该用户讲话完毕后则让出该反向信道,空出的该反向信道可以分配给该小区内提出申请并获得成功的集群组其他用户。 Fixed allocation shared reverse channel, for all the cluster is assigned a fixed set of user reverse channel in the same cell in advance, users need to apply his speech, to provide the fixing of the reverse channel to the user use, after the user finished his speech is let out of the reverse channel, vacated the reverse channel can be assigned to an application made within the cell and be successful cluster group of other users.

动态分配共享反向信道,是在有用户申请讲话时,才为其分配反向信道,该用户讲完后即释放(回收)该反向信道,下次同一小区内有用户申请讲话时,再重新申请和重新分配反向信道。 Dynamically allocated shared reverse channel, when the user is in speech applications, it assigns the reverse channel, the user is finished after release (recovery) of the reverse channel, the user has to apply the next speaking the same cell, then and re-apply reverse channel reallocation.

两种分配方法的共同特征是在同一时间内,为一个小区内同一个集群组的所有用户分配至多一条反向信道。 A common feature of the two allocation methods is at the same time within one cell with all users assigned a cluster of up to a group reverse channel.

以VGCS业务为例,说明本发明的固定分配与动态分配反向信道的实现方法。 In VGCS service as an example, the method described persistent allocation according to the present invention is implemented with dynamic allocation of the reverse channel. VGCS业务的一个重要特点是:所有集群组业务用户同时听,但是在同一时间内至多只能有一个集群组业务用户讲话。 An important feature of the business is VGCS: All cluster group of users at the same time listen, but at the same time at most only one cluster group of users speak. 所以在同一个小区里,不管只有一个用户还是有多个用户,完全可以建立一条前向广播信道和一条反向共享信道。 So in the same district, whether there is only one user or multiple users, you can establish a pre-shared channel to broadcast channels and one reverse. 由于所有用户可以同时只监听一个前向信道就能达到大家同时听到的目的,又由于在同一时间内至多只有一个用户允许讲话,所以只分配一条前向广播信道和一条反向信道就可以满足VGCS业务需求了。 Since all users can simultaneously monitor only a while before we can achieve the purpose of the hearing to the channel, and because at the same time at most only allow a user to speak, only to meet a pre-assigned to the broadcast channels and one reverse channel VGCS business needs.

参见图1,图中示出VGCS业务固定分配反向信道的实现流程。 Referring to Figure 1, there is shown fixed allocation VGCS service reverse channel implementation process.

步骤11,基站子系统(BSS)中的基站控制器收到VGCS业务的资源指配请求时,根据消息中的服务小区列表,分配服务小区指配资源,其中在每个小区内至多只指配一条前向用于广播消息的信道和一条供小区内所有VGCS业务用户讲话的共享反向信道;步骤12,当小区内有VGCS业务用户申请讲话且网络侧已经授权时,则基站子系统(BSS)中的基站控制器告诉该申请用户,供其使用的反向信道是已经分配好的相应小区的共享反向信道;步骤13,该申请用户讲话完毕后即让出所分配的该共享反向信道;步骤14,当同一小区其他VGCS业务用户申请讲话并成功时,BSS中的基站控制器将该共享反向信道再分配给其他用户使用,该分配的固定共享反向信道直至该次VGCS业务停止时才释放。 Step 11, the resource base station subsystem (BSS) is a base station controller receives a VGCS assignment request service refers to, according to the list of service message cell, cell assignment resource distribution service, wherein in each cell, at best assignment Previous to the channel for the broadcast message and a VGCS service for all users in the cell speech shared reverse channel; step 12, when a user applies VGCS service network has been authorized to speak, and the cell, the base station subsystem (BSS ) in the base station controller tells the user application, which is used for reverse channel has been assigned a respective shared reverse channel good cell; step 13, after which application the user is finished speaking have a shared reverse channel allocated ; step 14, when the same cell other application speech VGCS service users and successfully, the base station controller in the BSS shared reverse channel reassignment to other users, the allocated shared fixed reverse channel until the stop time service VGCS when released.

参见图2,图中示出VGCS业务动态分配反向信道的实现流程。 Referring to Figure 2, there is shown the process to achieve dynamic allocation VGCS service reverse channel.

步骤21,BSS中的基站控制器收到VGCS业务的资源指配请求时,根据消息中的服务小区列表,分配服务小区指配资源,其中在每个小区内至多只指配一条前向用于广播消息的信道,但暂不指配反向信道。 Step 21, the resource controller receives the base station in the BSS VGCS assignment request service refers to, according to the list of service message cell, cell assignment resource distribution service, wherein at most only means within each cell for the front with a broadcast message channel, but temporarily assigned reverse channel. 至多只指配一条前向用于广播消息的信道,是因为有些小区内可能没有VGCS业务用户,系统可以根据自己的策略不分配前向广播信道;步骤22,当小区内有VGCS业务用户申请讲话,且网络侧已经授权,则BSS中的基站控制器动态申请一个反向信道,供相应小区内的该VGCS业务用户使用;步骤23,BSS中的基站控制器收到该VGCS业务用户讲话结束的信令后,则回收该反向信道;步骤24,当该小区内其他VGCS业务用户申请讲话并成功时,BSS中的基站控制器再次申请一条反向信道。 Up to just before the assignment of a forward channel for the broadcast message, is because there may not VGCS service users, the system can track a broadcast channel before is not allocated according to their own policy within some cell; step 22, when the inner cell VGCS service user application speech and the network side has been authorized, the BSS station controller dynamically apply a reverse channel, for the user VGCS service within a corresponding cell use; step 23 is, the BSS the base station controller receives the user ends the speech service VGCS after signaling, then recovering the reverse channel; step 24, when the cell within other speaking VGCS service users and applications successfully, the BSS of the base station controller to re-apply a reverse channel. 这样,在同一时间内一小区内至多只有一条反向信道。 Thus, in a cell within the same time at most only one reverse channel.
