Description

呼叫控制设备及其呼叫控制方法技术领域该发明涉及进行无线通信的呼叫控制设备及其呼叫控制方法,特别涉及在无线一键通系统中进行无线通信的呼叫控制设备及其呼叫控制方法。 Call control device and a call control method Technical Field The invention relates to a call control device and a call control method for wireless communication, and particularly relates to a call control apparatus and a call control method for wireless communication in a wireless PTT systems. 背景技术在OMA (Open Mobile Alliance:开放移动联盟)组织中,规定了用于3GPP和3GPP2的无线一键通应用。 BACKGROUND ART In OMA (Open Mobile Alliance: Open Mobile Alliance) tissue, provides for the PoC application of 3GPP and 3GPP2. 其中,OMA负责规定与接入技术无关的无线一键通的技术规范。 Wherein the predetermined charge of independent OMA specifications and access technology of PoC. 3GPP和3GPP2负责发展与具体无线网络相关的无线一键通技术规范。 PoC technical specification 3GPP and 3GPP2 responsible for the development associated with a particular wireless network. 无线一键通(PoC: Push-to-talk over Cellular)是蜂窝通信网络的重要应用之一,它提供了一种可以允许用户与一个或多个其它用户即时通信的通信方式,从而提供一种类似步话机的业务。 A push to talk (PoC: Push-to-talk over Cellular) is an important application of the cellular communication network, it provides a user may allow one or more other users of the instant messaging communication mode, thereby providing a walkie-talkie service. 在无线一键通应用中,多个无线一键通客户端组成一个群组。 In PoC applications, a plurality of PoC client form a group. 在一个群组中同时只能有一个无线一键通客户端发送音频数据流,其它无线一键通客户端作为接收者接收音频数据流。 In one group while only one PoC client transmitting the audio data stream, the other PoC client as a receiver for receiving audio data stream. 无线一键通客户端的音频数据流发送由无线一键通服务器通过分发令牌来控制,只有得到令牌的无线一键通客户端可以发送音频数据流。 The audio data stream PoC client by the PoC server is controlled by a distributed token, only with PoC client token may transmit audio data stream. 为了在无线一键通客户端和无线一键通服务器之间交换令牌的相关信息,需要在他们之间传输控制消息等消息。 For information exchange between tokens PoC client and the PoC server, they need to transmit control messages between the message and the like. 在有无线一键通客户端发送音频数据流时,无线一键通服务器接收音频数据流并向每个无线一键通客户端转发。 When there is a push to talk client transmits audio data stream, the PoC server receives an audio data stream and forwards each PoC client. 如果采用单播来发送音频数据包,则无线一键通服务器需要向群组中的每个无线一键通客户端发送一份音频数据包的拷贝,这样会存在造成网络中的资源浪费的问题,同时当群组中用户数增加时,也会存在增加无线一键通服务器的负担的问题。 If audio data is transmitted to a unicast packet, the PoC server needs to send a copy of the audio data packet to each of the group PoC client, this will cause a problem in a waste of resources in a network while when the number of users in a group increases, there will increase the burden of the PoC server problem. 针对这些问题,美国专利US6,141,347A号公报公开了一种提高无线一键通服务器和网络传输的效率的方法,主要采用组播来传输音频数据包,从而节省网络中的资源。 To solve these problems, U.S. Patent Publication No. US6,141,347A discloses a method of increasing the efficiency PoC server and transmitted over the network, mainly multicast to transmit audio packets, thereby saving resources in the network. 但是,通常的蜂窝通信网络(例如无线一键通)并不能支持组播, 为了在蜂窝通信网络中支持组播,3GPP2组织提出了BCMCS(Broadcast /Multicast Service组播/广播业务)来支持蜂窝通信网络中的组播业务(3GPP2 X. S0022-0 "Broadcast and Multicast Service in cdma2000 Wireless IP network"),从而同时向多个用户发送同样的数据。 However, conventional cellular communication network (e.g., PoC) does not support multicast, in order to support multicast in a cellular communications network, 3GPP2 organization proposed BCMCS (Broadcast / Multicast Service broadcast / multicast service) to support cellular communication multicast service network (3GPP2 X. S0022-0 "Broadcast and multicast service in cdma2000 Wireless IP network"), so as to send the same data to multiple users. 该技术使用空中接口的控制信道来同时向多个无线终端传输数据,通过采用该技术,可以在蜂窝网络中支持组播,这样当在基站和无线终端之间只有下行组播数据传输时,就可以释放无线终端和基站之间的单播信道资源,从而减少单播信道的资源消耗。 This technique uses a control channel over the air interface simultaneously to multiple wireless terminals transmit data by using this technique, the cellular network supports multicast, so that only when the downlink multicast data transmission between a base station and a wireless terminal, to unicast channel may release resources between the wireless terminal and a base station, a unicast channel to reduce resource consumption. 这种技术适用于在3G系统中支持无线一键通类型的群组业务。 This technique is suitable for supporting a push to talk type of group service in the 3G system. 在3GPP2标准中采用BCMCS控制器来完成在蜂窝网络中组播信道的控制功能。 Using standard 3GPP2 BCMCS controller to complete the control function in the cellular network multicast channel. 另一方面,美国专利US6,141,347A号公报的技术采用分布式控制方式,在不同终端之间只传送音频数据流,这种分布式控制方式不能对群组进行有效的管理,在群组通信中不同终端之间可能产生冲突。 On the other hand, U.S. Patent Publication No. US6,141,347A distributed control technique, only the audio streams transmitted between different terminals, such a distributed control can not effectively manage the group, in the group communication conflict may occur between different terminals. 因此在OMA的规范中定义了无线一键通服务器来对群组进行控制,这就需要在无线一键通客户端和无线一键通服务器之间除了传送音频数据流,还需要传送控制消息来完成群组控制功能。 Thus defines the PoC server to the OMA specification control group, which requires in addition to transmitting audio data stream, but also needs to transmit control messages between PoC client and PoC server complete group control function. 在OMA的规范中定义了TBCP (Talk Burst Control Protocol, Talk Burst控制协议)作为群组控制消息。 Defines the TBCP (Talk Burst Control Protocol, Talk Burst Control Protocol) in the OMA specification as a group of control messages. OMA的无线一键通标准中,除了音频,还需要在客户端和服务器之间传输控制消息,即TBCP (Talk Burst Control Protocol)消息。 OMA PoC standard, in addition to the audio, but also between the client and the server transmission control message, i.e., TBCP (Talk Burst Control Protocol) message. 但在现有技术中,只考虑了用组播传输音频,而没有考虑用组播传输控制消息。 However, in the prior art, only consider the multicast transmission of the audio, without considering control message multicast transmission. 这样一来,如果在无线一键通客户端和无线一键通服务器之间采用单播方式发送TBCP消息等控制消息,即使无线一键通客户端通过BCMCS 接收音频数据流,仍然需要无线一键通客户端维持单播信道来传送控制消息,空中接口的单播信道资源仍将被占用,这样存在造成信道资源的浪费的问题。 Thus, if the unicast between the PoC client and the PoC server transmits a control message TBCP messages, etc., even if the PoC client receives audio data stream through the BCMCS, there remains a need a Push the client is maintained through a unicast channel to transmit a control message, a unicast channel of the air interface resources will be occupied, so the presence of wasteful channel resources. 发明内容本发明的目的在于提供一种通过网络与多个终端连接的呼叫控制设备及其呼叫控制方法,可以有效减少控制消息在网络中的重复传送, 以减少资源消耗。 Object of the present invention to provide a call control apparatus and a control method of connecting a call through a network with a plurality of terminals, can effectively reduce the repeatedly transmitted control message in the network in order to reduce resource consumption. 为了达成上述目的,本发明的通过网络与多个终端连接的呼叫控制设备的呼叫控制方法,其特征在于包括以下步骤:接收步骤,经由上述呼叫控制设备的网络接口,接收从上述多个终端中的某一个发送来的请求呼叫控制消息;确定步骤,通过检索存储在上述呼叫控制设备的存储装置中的、将用于对上述多个终端与上述呼叫控制设备之间的会话进行控制的呼叫控制消息、与表示上述呼叫控制消息的传输方式是单播还是多播的通信类型对应起来存储的控制信息管理表,来确定与所接收到的上述请求呼叫控制消息相对应的响应呼叫控制消息的通信类型和发送到的终端;以及发送步骤,根据上述通信类型,经由上述网络接口向上述确定的终端发送上述响应呼叫控制消息。 To achieve the above object, the method of call control of the call control apparatus connected through a network with a plurality of terminals according to the present invention, comprising the steps of: receiving step, the call control via the network interface device, received from said plurality of terminals the request sent by one call control messages;

controlling a plurality of PoC client 21, 22, 23 for controlling transmission of a plurality of call control messages and session establishment 11 between the PoC server. 在无线一键通服务器11经由网络接口210接收到从多个无线一键通客户端21、 22、 23中的某一个发送来的请求呼叫控制消息时,控制单元201通过检索信令管理表204来确定与所接收到的请求呼叫控制消息相对应的响应呼叫控制消息的通信类型,并根据将该响应呼叫控制消息的内容来确定发送到哪个无线一键通客户端。 11 upon receiving the 21, 22, 23 in one of a request transmitted from a plurality of PoC client via the network interface call control message the PoC server 210, the control unit 201 by retrieving signaling management table 204 determining a received request to the call control message and corresponding response message, the call control type of communication, and determine which transmit to the PoC client according to the content of the response to the call control message. 令牌控制模块203根据来自无线一键通服务器的请求呼叫控制消息,来确定应当回发给相应无线一键通服务器的与该请求呼叫控制消息相对应的响应呼叫控制消息,并将该响应呼叫控制消息通知给信令传输控制模块202。 Token control module 203 according to a request from a call control message PoC server, should be sent back to corresponding determined PoC server corresponding to the response to the call request control message to the call control message, and the response to a call a control message is sent to signaling control module 202. 信令传输控制模块202检索存储在硬盘中204中的呼叫控制信息管理表301来确定该响应呼叫控制消息的通信类型,再根据检索到的通信类型来检索组播地址管理表302和单播地址管理表303来确定与该响应呼叫控制消息的通信类型相对应的传输地址,即确定将该响应呼叫控制消息发送到哪个无线一键通客户端。 Control signaling module 202 retrieves stored in the hard disk 204 in the call control information management table 301 to determine if the response to a call control message communication type, and then to retrieve the multicast address management

server control unit 201 signaling the control module 202. 在接收到要从无线一键通服务器11发送到无线一键通客户端的响应呼叫控制消息(步骤501)之后,信令传输控制模块202检索呼叫控制消息管理表301,来判断该响应呼叫控制消息的通信的类型是否是组播(步骤502)。 After receiving from the PoC server sends a response to a call to the PoC client control message (step 501) 11, signaling control module 202 retrieves a call control message management table 301 to determine whether the response to the call control message whether the type of communication of the multicast (step 502). 若在步骤502中判断的结果是"否",即,该响应呼叫控制消息的类型是"一对一",则信令传输控制模块202检索单播地址管理表303, 获得向相应无线一键通客户端发送该响应呼叫控制消息的单播地址(步骤504),然后,采用单播地址来传输该响应呼叫控制消息(步骤505)。 If the determination result of step 502 is "NO", i.e., the type of response to a call control message is "one", the signaling control module 202 retrieves unicast address management table 303, to obtain a corresponding radio button the client sends via the call control message in response to a unicast address (step 504), then unicast address in response to the transmission of the call control message (step 505). 若在步骤502中判断的结果是"是",即,该响应呼叫控制消息的类型是"一对多",则信令传输控制模块202检索组播地址管理表302, 获得向所有无线一键通客户端发送该响应呼叫控制消息的组播地址(步骤503),然后,采用组播地址来传输该响应呼叫控制消息(步骤505)。 If the determination result of step 502 is "YES", i.e., the response type is a call control message of "many", the signaling control module 202 retrieves the multicast address management table 302, to obtain a key to all wireless the client sends via the call control message in response to a multicast address (step 503), then, the multicast address is transmitted in response to a call control message (step 505). 图5^是示出了本发明涉及的无线一键通系统的信令流程。 FIG. ^ 5 is a flow diagram illustrating a signaling PoC system according to the present

double-dashed lines with arrows indicate multicast signaling messages, the dashed line with an arrow indicates the media stream. 首先,在无线一键通客户端21和无线一键服务器11之间,通过SIP 协议建立会话。 First, between the PoC client 21 and a push server 11 to establish a session through the SIP protocol. 在建立了会话之后,无线一键通客户端21就可以发送请求呼叫控制消息来请求令牌。 After a session is established, the PoC client 21 may send a request to a call control message to request tokens. 如图5所示,无线一键通客户端21用单播向无线一键通服务器11发送作为请求呼叫控制消息的TBCP请求消息(401)。 5, the PoC client 21 as a TBCP by unicast control message requesting a call request message (401) to the PoC server 11. 接着,无线一键通服务器11接收到该TBCP请求消息之后, 检査令牌是否被其它无线一键通客户端22、 23占用(402)。 Next, the PoC server 11 receives the request after the TBCP message, checks whether the end of the token 22, 23 occupied by (402) other PoC client. 若令牌没有被占用,则无线一键通服务器11响应该TBCP请求消息,向无线一键通客户端21发送作为响应呼叫控制消息的TBCP授权消息(404)。 If the token is not occupied, the PoC server 11 in response to the request TBCP message, to the PoC client 21 sent in response to a call control message TBCP authorization message (404). 同时, 无线一键通服务器11向其它所有无线一键通客户端22、 23发送作为响应呼叫控制消息的TBCP占用消息(405),通知令牌己被占用。 Meanwhile, the PoC server 11 side to all other PoC clients 22, 23 occupy TBCP message sent as a response (405) of the call control message, the notification had been occupied by the token. 另外,无线一键通服务器11在发送响应呼叫控制消息之前,控制单元201通过检索呼叫控制信息管理表301来确定与所接收到的作为请求呼叫控制消息的TBCP请求消息相对应的响应呼叫控制消息的通信类型(403)。 Further, the PoC server 11 before sending the response to a call control message, the control unit 201 determines TBCP request message is a call control message received as a request by retrieving the call control information management table 301 corresponding to the response to the call control message the communication type (403). 例如,当确定TBCP授权消息是"一对一"类型时,通过单播向无线一键通客户端21传输该TBCP授权消息;当确定TBCP占用消息是"一对多"类型时,通过组播向无线一键通客户端22、 23传输该TBCP占用消息。 For example, when it is determined TBCP authorization message is "one to one" type, the PoC client 21 transmits the grant message via a unicast TBCP; when it is determined occupancy TBCP message is a "one to many" type, multicast the PoC client 22, 23 occupied by the transmission of the TBCP message. 接着,无线一键通客户端21接收到TBCP授权消息后,开始向无线一键通服务器11发送音频流等媒体流,而无线一键通客户端22、 23接收到TBCP占用消息后,开始接收由无线一键通服务器11转发的来自无线一键通客户端21的音频流等媒体流(406)。 Subsequently, the PoC client after 21 received TBCP authorization message, it begins to flow to the PoC server 11 transmits audio stream media, the PoC client 22, 23 received TBCP occupancy message, starts receiving the PoC server 11 forwards the audio stream from the PoC client 21 of the media stream (406). 另一方面,当无线一键通客户端21结束音频流等媒体流的发送并释放令牌时,会通过单播向无线一键通服务器11发送作为请求呼叫控制消息的TBCP释放消息(407)。 On the other hand, when the PoC client end of transmission media audio stream stream 21 and releases the token, it will send a unicast request to the call control message PoC server 11 TBCP Release message (407) . 无线一键通服务器11接收到该TBCP 释放消息后,检査令牌状态(408),并将作为响应呼叫控制消息的TBCP 空闲消息通知给全部无线一键通客户端21、 22、 23。 PoC server 11 after receiving the release TBCP message, check the status of the token (408), and as a response to the call control message notified to all idle message TBCP PoC client 21, 22, 23. 然后,控制单元201通过检索呼叫控制信息管理表301来确定该TBCP空闲消息的通信类型(409)。 Then, the control unit 201 determines the type of communication (409) the idle TBCP message control information management table 301 by retrieving the call. 例如,当确定该TBCP空闲消息是"一对多"类型时,无线一键通服务器11通过组播向无线一键通客户端21、 22、 23传输该TBCP 空闲消息(410)。 For example, when it is determined that the idle TBCP message is "one to many" type, the PoC server 11 via multicast to the PoC client 21, 22, 23 transmitting the idle TBCP message (410) side. 这样一来,对于只接收呼叫控制消息的客户端来说可以释放空中接口用于单播信道的无线资源,从而减少无线资源消耗。 Thus, only the receiving call control messages for a client who can release the air interface radio resources for unicast channel, thereby reducing radio resource consumption. 再者,无线一键通服务器如上所述地控制呼叫控制消息的通信的类型,可以有效减少呼叫控制消息在网络中的重复传送,以减少资源消耗,从而可以提高蜂窝网络资源的利用率。 Further, the PoC server as described above call control message of the type of communication, can effectively reduce the call control message is repeatedly transmitted in the network, in order to reduce resource consumption, thereby improving utilization of resources of the cellular network.

number of cases. 而且,例如在上述实施方式中,控制单元由信令传输控制模块和令牌控制模块来构成以实现其功能,但显然只要能实现其功能,既可以由一个模块构成, 也可以由三个以上模块构成。 Further, for example, in the above-described embodiment, the control unit by a signaling control module and token control module configured to implement its functionality, but obviously as long as its function, may be constituted by a module, it may be composed of three or more modules. 另外,例如在上述实施方式中,存储在作为存储装置的硬盘中的信令管理表(即控制信息管理表)包括呼叫控制信息管理表、单播地址管理表及组播地址管理表这三个表,但只要能通过检索该信令管理表而得到在无线一键通客户端和无线一键通服务器之间传送的呼叫控制消息的传输方式或传输地址也可以合并为一个表格,或者分拆为更多表格, 而表格里的项目也可以根据需要来具体设定。 Further, for example, in the above embodiment, the storage in the hard disk as a storage device management table in the signaling (i.e., control information management table) includes a call control information management table, the management table unicast address and multicast address management table of the three table, as long as the management table by retrieving the signaling call control messages obtained between PoC client and the PoC server transmits a transmission or transport address may be combined into one table, or split for more table, and the table in the project can also be set according to specific needs. 另外,例如在上述实施方式中,在控制消息管理表中主要存储了由无线一键通服务器发送给无线一键通客户端的响应呼叫控制消息,但也可以根据需要而存储由无线一键通客户端发送给无线一键通服务器的请求呼叫控制消息等其它控制消息。 Further, for example, in the above embodiment, the control message management table mainly stores the sent by the PoC server to the response PoC client call control message, it may be stored as required by the PoC Client sends a request to a PoC server, a call control messages and other control messages. 另外,本发明能广泛地应用于产业中,不仅可用于无线一键通系统, 也可以用于其它群组通信应用。 Further, the present invention can be widely used in the industry, not only to the PoC system, may also be used for other group communications applications. 例如在无线视频会议系统中,也可以采用该技术来提高系统的资源利用率。 For example, in wireless video conference system, the technique may also be employed to improve the utilization of the system resource.
