- the present invention relates to the field of digital trunking communications, and in particular to a cluster terminal call dispatcher technology.
- BACKGROUND OF THE INVENTION Mobile communication technology has been developed to the third generation, and cluster communication has increasingly become an indispensable communication service.
- Cluster communication refers to a dedicated scheduling communication method, including dedicated command and dispatch communication. In use, cluster users can join calls at the same time, and the call works in simple mode. Broadly speaking, various wireless communication systems with scheduled communication functions, including wireless intercom systems, can be included in the scope of trunked communication systems.
- the cluster communication has experienced a single intercom system (one pair of talks) to a single base station small system (in the same frequency simplex network form, different frequency single (double) work network form, single ⁇ f words and one call form, With the choice of call form, multi-channel automatic dialing), to the development of large-capacity multi-zone systems (multi-channel user sharing), and then experienced a leap from analog cluster to digital cluster, this leap makes cluster communication in the letter More reliable digital processing methods can be used for coding, multiple access methods, speech coding, modem technology, synchronization techniques, error detection and error correction, and diversity techniques.
- the two widely used digital trunking systems are iDEN (Integrated Digital Enhanced Network) and TETRA (Terestrial Trunked Radio) based on TDMA multiple access technology, in order to promote the scale application of digital trunking systems, and further improve the frequency resource utilization, cluster communication.
- the system has a new application trend in application, which is to combine multiple digital cluster systems for unified use and management, so as to achieve the purpose of sharing channels and channels, sharing coverage areas, communication services, and sharing costs.
- the cluster application has evolved from targeting individual professional users to implementing common network operations for multiple group users.
- the development of trunking communication from the private network to the common network has promoted the research on cluster technology on the existing public network (GSM, CDMA).
- a cluster terminal in the digital trunking communication field calls the dispatching station
- the system determines the route of the target address according to the location information of the calling user. For example, dispatchers in different regions share the same dispatching station number, and the dispatching authority between dispatchers is divided according to the location area.
- the system selects the corresponding dispatcher to access according to the location area of the calling party. , to facilitate the deployment of resources, improve call processing 3 ⁇ 4 force.
- an existing cluster terminal calls the dispatching station, it generally limits the number of users that can be called in or out according to the location area, the cell or the area i or the latitude and longitude of the terminal.
- the prior art generally requires coordination of a positioning system (GPS), a mobile switching center (MSC), or a packet switched service node (PDSN) to establish local Correspondence between the path and the transmission area number (LATA).
- GPS positioning system
- MSC mobile switching center
- PDSN packet switched service node
- LATA transmission area number
- the PHR switcheduling home register
- the PDS switcheduling server
- the paging command carries the location information of the calling party; the dispatching station selects a specific dispatcher to complete the current call.
- the DAS ⁇ finds the available dispatcher according to the location information of the calling user, and if there is a dispatcher available, notifies the dispatcher of the call request; if no dispatcher is available, the default dispatcher is paged; The dispatcher responds to the page, the call is successfully established; the dispatcher does not respond, and the call is rejected.
- the conditions of the available dispatcher are: The dispatcher currently has an operational dispatcher, and the dispatcher’s jurisdiction The area includes the location area where the caller is located, and the dispatcher has the authority to schedule the caller. When there are multiple available dispatchers, the first call is established, and the other is automatically canceled.
- the location information of the calling party in the present invention may be a physical cell, a region, or a logical scheduling location area.
- the difference between the present invention and the prior art is that instead of restricting the call, the call is directed to the dispatcher of the nearest service, and a plurality of dispatchers share a unified dispatching station number.
- the system automatically Access to the nearest dispatcher, which makes it easy to provision resources and handle call problems. It can be realized only by relying on the equipment of the cluster system itself.
- FIG. 3 is a flow chart of a cluster user call scheduling station of the present invention.
- DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The implementation of the technical solution will be further described in detail below with reference to the accompanying drawings:
- the network structure diagram of the digital cluster is shown in Fig. 1, and the components are as follows:
- MS A cluster terminal, which can support terminal devices for storing user information, group information, scheduling location area judgment, and responding to paging and other cluster services;
- BSS base station subsystem, including a transceiver supporting a trunked call (BTS), a base station controller (BSC), and a scheduling client (PDC) that interacts with the network side;
- BTS trunked call
- BSC base station controller
- PDC scheduling client
- PDS scheduling server, implementing call control and call rights management functions for trunk calls
- PHR Scheduling the home register, storing the registration information and location information of the cluster users and groups, including the mapping relationship between the dispatcher/dispatcher/location area, realizing the authentication, authorization and charging functions of the cluster users, and the location Update and group management functions;
- PHR Agent Acceptance station, which can directly manage groups, groups and users, such as assigning rights;
- DAS The dispatcher server processes the service request sent by the dispatcher client;
- the dispatcher client including the dispatching station and the management station.
- the dispatching station performs scheduling operations by the dispatcher, including initiating calls, querying status, recording, etc.;
- the management station performs management operations such as group division and user authority by the administrator;
- the location-based routing of the dispatcher and dispatcher is set at the management station.
- Figure 2 is an example of a scheduling location area, as explained below:
- the Dispatch Location Area schedules the location area, and the scheduling location area is a logical 4, which consists of one or more cells.
- the operator divides the coverage network of the system into several scheduling location areas according to the actual needs of the network planning.
- the invention firstly plans a location area according to system scheduling requirements, and the location area can be divided according to the principle of a small area, a region or a scheduling location area.
- the scheduling location area is a logical concept, and the smallest unit is a cell or a collection of multiple cells. Taking FIG. 2 as an example, the DLA 200 is a set of the cell 201, the cell 202, and the cell 203.
- the invention proposes a logical scheduling location area, which is more in line with the cluster system service features.
- one or more scheduling location areas may be further formed into a scheduling service area.
- the present invention divides the dispatcher subordinate to the dispatching station according to the jurisdictional location area, establishes a mapping relationship between the dispatching station/dispatcher/location area, and saves the corresponding relationship in the PHR;
- FIG. 3 is a cluster user of the present invention.
- Call dispatcher flow chart The scheduling area (cell, area, or scheduling location area) is divided within the network coverage as needed, and the dispatcher subordinate to the dispatching station is divided according to the jurisdictional location area, and the correspondence between the dispatching station/dispatcher I location area is established.
- the steps when the cluster terminal calls the adjustment degree station are as follows:
- the cluster terminal initiates a call to the dispatching station
- the PDS sends an Access-Request message to the PHR to request the primary/called user to authenticate.
- the PHR analyzes that the called party is the dispatching station. After the authentication is passed, the PDS sends a call dispatching station command to the DAS, and the command carries the information about the calling position.
- the DAS further determines whether the dispatcher has a qualified dispatcher, and the judgment condition is:
- the current dispatcher has an operable dispatcher; the dispatcher can schedule the location area to include the location area where the caller is located, and the dispatcher has the authority to schedule the user. These conditions are met at the same time as qualified dispatchers.
- the DAS If there is a dispatcher that satisfies the condition, the DAS notifies the paging message to all dispatchers that meet the conditions. Since there may be more than one dispatcher who meets the conditions at the same time, the system takes all notifications, and one dispatcher responds first, and the other dispatchers automatically cancel the principle of answering authority.
- the DAS If there is no dispatcher that satisfies the condition, the DAS notifies the default dispatcher of the paging message.

Description
一种数字集群呼叫中基于位置路由的实现方法 技术领域 本发明涉及数字集群通信领域, 具体涉及集群终端呼叫调度台技术。 背景技术 移动通信技术已经发展到第三代,其中集群通信也日益成为一种不可或缺 的通讯业务。 集群通信是指一种专用的调度通讯方式, 包括专用指挥和调度通 信, 在使用中集群用户可以同时加入呼叫, 通话以单工方式工作。 从广义上讲, 包括无线对讲系统在内的具有调度通信功能的各种无线通信系统均可纳入集 群通信系统的范畴。 集群通信经历了筒单对讲系统(一对一对讲形式)到单基站小系统(同频 单工组网形式、 异频单 (双) 工组网形式、 单^ f言道一呼百应形式、 带选择呼叫 形式、 多信道自动拨号形式), 再到大容量多区域系统(多信道用户共享形式) 的发展历程, 后又经历了从模拟集群到数字集群的飞跃, 这个飞跃使得集群通 讯在信令编码、 采用的多址方式、 语音编码、 调制解调技术、 同步技术、 检错 纠错以及分集技术等方面均可以釆用更可靠的数字处理方式。 目前广泛应用的 两种数字集群系统是基于 TDMA多址技术的 iDEN( integrated Digital Enhanced Network )和 TETRA ( Terrestrial Trunked Radio ) , 为了促进数字集群系统的规 模应用, 同时进一步提高频率资源利用率, 集群通信系统在应用上出现了一个 新的应用趋势, 就是将多个数字集群系统结合在一起统一使用和管理, 从而达 到能够共用频道和信道, 共享覆盖区域、 通信业务, 共担費用的目的, 最终将 集群应用从面向个别专业用户发展为面向多个集团用户实现共网运营。 集群通信由专网向共网的发展促进了在现有公网 (GSM、 CDMA ) 上实 现集群技术的研究。 数字集群通信领域中的集群终端呼叫调度台时, 集群用户拨打特殊号码 (一般是调度台号码或呼叫处理中心) 时, 系统根据主叫用户所在的位置信息 确定目标地址的路由。 例如, 不同地域的调度员共享同一个调度台号码, 各调 度员之间的调度权限才 据位置区域进行划分, 用户呼叫调度台时, 系统根据主 叫所在位置区域选择对应的调度员就近接入, 以方便调配资源, 提高呼叫处理
¾力。 现有的集群终端呼叫调度台时,一般根据终端所在位置区、蜂窝小区或所 it区 i或经纬度进^"路由, 限制可以呼入或呼出的用户列表。 相关专利如 JS6724882 , CN03157508和 CN03148343等。 这些专利有一共同的特点, 都是 需要在 MSC侧进行判断, 建立位置区与号码筛选目录之间的映射关系实现, 以 CN03157508为例, 它介绍了一种在无线调度系统中, 在网关移动交换中心 '拜访地移动交换中心(GMSC/VMSC )处, 建立调度员终端号码与区域分布的 V1SC/VL 号之间和其调度区域与分布在该 VMSC的小区号之间的对应关系, 当调度员发起呼叫时, 在此处进行仲裁, 以实现调度员呼叫限制的方法。 现有技术一般需要定位系统 ( GPS )、 移动交换中心 ( MSC )或分组交换 服务节点(PDSN )的配合, 建立局部通路与传输地区号(LATA )的对应关系。 发明内容 本发明要解决的技术问题是,针对现有技术存在的问题,提出一种依靠集 群系统本身设备即可实现集群终端呼叫在不同区域的调度台的方法。 本发明包"^以下步骤:
1. 1 根据需要在网络覆盖范围内划分调度区域(小区、 地区或调度位置 区);
1. 2 将调度台下属的调度员根据管辖位置区域进行划分,建立调度台 /调 度员 /位置区域之间的对应关系,并将该对应关系保存在 PHR中;
1. 3 当终端呼叫调度台时, PHR (调度归属寄存器)分析出被叫是调度台, 鉴权通过后, PDS (调度服务器)向 DAS (调度台服务器)发送寻呼被叫调度 台指令, 寻呼指令中携带主叫的位置信息; 调度台选择特定的调度员, 完成本 次呼叫。 在上述方案中, DAS ^^据主叫用户的位置信息查找可用调度员, 如果有 可用调度员, 则将呼叫请求通知给这些调度员; 如果没有可用调度员, 则寻呼 缺省调度员; 调度员响应寻呼, 呼叫建立成功; 调度员不响应, 呼叫拒绝。 可用调度员的条件为: 调度台当前存在可操作的调度员,该调度员的管辖
区域包括主叫所在的位置区域, 并且该调度员具有对主叫用户调度的权限。 当 有多个可用调度员时, 先响应的建立呼叫, 其他的自动取消应答权限。 本发明中的主叫的位置信息可以是物理上的小区、地区或逻辑上的调度位 置区。 本发明与现有技术的区别在于, 不是限制呼叫, 而是把呼叫引导到最近服 务的调度员, 多个调度员之间共享统一的调度台号码, 当用户在不同的地理位 置拨打, 系统自动接入最近的调度员, 可以方便调配资源, 处理呼叫的问题。 仅依靠集群系统本身设备即可实现。 附图说明 图 1 是数字集群通信系统基本的网络架构示意图; 图 2 是调度位置区示例图; 图 3是本发明的集群用户呼叫调度台流程图。 具体实施方式 下面结合附图对技术方案的实施作进一步的详细描述: 数字集群的网络结构图如图 1 , 各组成部分说明如下:
MS: 集群终端, 能够支持存储用户信息, 群组信息, 调度位置区域判断, 响应寻呼等集群业务的终端设备;
BSS:基站子系统,包括支持集群呼叫的收发信机( BTS ),基站控制器( BSC ) 和与网络侧交互的调度客户端 (PDC );
PDS: 调度服务器, 实现集群呼叫的呼叫控制、 话权管理等功能;
PHR: 调度归属寄存器, 保存集群用户和群组的注册信息和位置信息、 包 括调度台 /调度员 /位置区域之间的映射关系, 实现对集群用户的鉴权、 授权和 计费功能, 以及位置更新和群组管理功能;
PHR Agent: 受理台, 可直接对集团、 组和用户进行管理, 如分配权限等;
DAS: 调度台服务器, 处理调度台客户端发来的业务请求;
DAC: 调度台客户端, 包括调度台与管理台, 调度台由调度员进行调度操 作, 包括发起呼叫, 查询状态, 录音等; 管理台由管理员进行对组的划分, 用 户权限等管理操作; 调度台和调度员的基于位置路由在管理台设置。 图 2 是调度位置区示例图, 说明如下:
DLA: Dispatch Location Area调度位置区, 调度位置区是个逻辑 4既念, 由一个或多个小区构成。 运营商根据网络规划的实际需要, 将系统的覆盖网络 划分成若干个调度位置区域。 本发明首先要根据系统调度需求规划出位置区域, 位置区域可以按照小 区、 地区或调度位置区域原则划分。 调度位置区是个逻辑上的概念, 最小单位 为小区也可以是多个小区的集合。 以图 2为例, DLA200是小区 201、 小区 202 和小区 203—起组成的集合。 本发明提出了逻辑上的调度位置区, 更符合集群系统服务特色。 为了限制 集群服务的可服务范围, 可以进一步地将一个或者多个调度位置区域构成调度 服务区域。 本发明要将调度台下属的调度员根据管辖位置区域进行划分,建立调度台 /调度员 /位置区域之间的映射关系,并将该对应关系保存在 PHR中; 图 3 是本发明的集群用户呼叫调度台流程图。 在根据需要在网络覆盖范围内划分调度区域(小区、地区或调度位置区 ), 以及将调度台下属的调度员根据管辖位置区域进行划分,建立调度台 /调度员 I 位置区域之间的对应关系,并将该对应关系保存在 PHR 中的前提下, 集群终端 呼叫调节度台时的步骤如下:
301 : 集群终端发起对调度台的呼叫;
302: PDS向 PHR发送 Access- Request报文, 以请求主 /被叫用户鉴权。 PHR分析出被叫是调度台, 鉴权通过后, PDS向 DAS发送呼叫调度台指令, 指 令中携带主叫位置相关信息。
303: DAS进一步判断该调度台是否存在符合条件的调度员, 判断条件为:
当前调度台存在可操作的调度员; 该调度员可调度的位置区域范围包含了主叫 所在的位置区域,并且调度员具有对用户调度的权限。 这些条件同时满足, 为 符合条件的调度员。
304:如果存在满足条件的调度员,则 DAS将寻呼消息通知到所有满足条件 的调度员。 因同时满足条件的调度员可能有多个, 系统采取全部通知, 一个调 度员先响应, 其他调度员就自动取消应答权限的原则。
305: 如果不存在满足条件的调度员,则 DAS 将寻呼消息通知到缺省调度 员。
306: 如调度员在应答定时器到之前响应了寻呼请求, 则呼叫建立成功。 如调度员应答超时、 拒绝应答, 则呼叫失败。
