步骤IOI,基站检测Abis接口传输,当检测到传输断链,基站进入孤站运行模式。 Step IOI, the base station detects Abis interface transmission, when the transmission is detected scission, the base station enters the solitary station mode of operation. 步骤102,基站在BCCH信道上广播系统消息,通知移动台已进入孤站运行模式,该系统消息在BCCH信道上进行周期性的广播。 Step 102, the base station on the BCCH channel broadcast system messages informing the mobile station has entered solitary station mode of operation, the system message periodically broadcast on the BCCH channel. 步骤103,移动台收到该BCCH信道上的表明基站处于孤站运行模式的系统消息后,移动台进入孤站运行模式。 After step 103, the mobile station receives the BCCH channel indicates that the base station is in a system message operation mode solitary station, the mobile station enters a lone station mode of operation. 由于移动台位置变化等原因,基站所辖服务区内移动台的数目和信息经常发生改变,因此需要及时更新MSISDN和IMSI对应关系表,以下为位置更新过程:步骤104,移动台发起位置更新流程,即通过完全层三位置更新业务请求消息向基站发起位置更新请求,在该消息中向基站提供IMSI和MSISDN 信息,并同时启动孤站运行模式位置更新定时器。 Due to mobile station location changes, the number and the information of the base station under the jurisdiction of the service area of ​​the mobile station frequently changes, it is necessary to update the MSISDN and IMSI correspondence table, the following is a location update process: Step 104, the mobile station initiates a location update procedure , i.e. a request by the three-position fully layer update service message initiates a location update request to the base station, providing the IMSI and MSISDN information to the base station in the message, and simultaneously start the solitary station operating mode location update timer. 步骤105,基站从收到的完全层三位置更新业务请求消息中取出IMSI 信息和MSISDN信息,保存在MSISDN和IMSI对应关系表中。 Step 105, the base station from the received complete layer IMSI information and MSISDN information message extracted three location update service request, is stored in MSISDN and IMSI correspondence table. 步骤106,基站给移动台发送位置更新接受消息,确认位置更新成功, 位置更新过程结束。 Step 106, the base station to the mobile station sends a location update accept message confirming the location update is successful, the end of the location update procedure. 如果移动台在孤站运行模式位置更新定时器超时之前仍然收不到基站返回的位置更新确认消息,则延迟一段时间后,再次发起位置更新过程,即重复执行步骤104 ~ 106。 If the mobile station to update timer solitary station operating mode position timeout still received before a position short of the base station returns the update confirm message, then after a delay, again initiates a location update process, i.e. repeating steps 104 to 106. 由于基站所辖移动台数目较多,在进行位置更新时可能会经常发生碰撞的情况,造成一些移动台的位置更新请求无法被及时处理,因此,这里需要这些移动台延迟一段时间后,再次发起位置更新过程。 Situation due to the larger number of base stations under the jurisdiction of the mobile station may collision will occur frequently during location update, resulting in the location update request some of the mobile station can not be in time, therefore, there is need for the mobile stations a time delay, launch again location update process. 并且,为了减小移动台位置更新请求碰撞的发生几率,可以设置所延迟的一段时间不固定,使该延迟时间通过一定的算法随机产生。 Further, in order to reduce mobile station position update the probability of occurrence of the request collision, may be provided as a delay period of time is not fixed, so that the delay time through a certain algorithm randomly generated. 另外,后续进入该基站覆盖范围内的移动台,接收BCCH信道上周期性广播的孤站运行系统消息后,也需发起位置更新过程,给基站提供IMSI和MSISDN信息。 After the addition, the follow-up into the mobile station within the coverage of base stations, receiving a lone station operating system message BCCH channel periodically broadcasts, but also needs to initiate a location update process, providing the IMSI and MSISDN information to the base station.

上面所述位置更新过程是在移动台进入孤站运行模式后的初始阶段,以及孤站运行模式位置更新定时器超时后发起的后续位置更新过程。 Above the location update process is an initial stage after the mobile station enters a lone station mode of operation, and the isolated station operation mode location update timer is initiated after the timeout subsequent location update procedure. 除此以外,为了使基站内部的MSISDN和IMSI对应关系表得到及时和可靠的更新, 还可以要求移动台周期性地发起位置更新过程。 In addition, in order to MSISDN the interior of the base stations and IMSI mapping table to obtain timely and reliable updated, may also require the mobile station to periodically initiate a location update procedure. 参见图2所示,在孤站运行模式下,移动台可以发起点对点呼叫,其具体过程如下:步骤201,移动台发起点对点呼叫,即在完成信道接入后,移动台向基站发送层三点对点业务请求消息,该消息中携带有被叫用户的MSISDN号码。 Referring to FIG. 2, in the solitary station operating mode, the mobile station may initiate point call, the specific process is as follows: Step 201, the mobile station initiates point call, i.e. after the completion of the channel access, the mobile station to the base station transmission layer three point a service request message, the message carries the called subscriber's MSISDN number. 其中,这里信道接入过程与GSM系统的现有信道接入过程相同。 Wherein, the same conventional channel access where a channel access procedure with the GSM system process. 步骤202,基站收到层三点对点业务请求消息后,根据消息中被叫用户的MSISDN号码查询本地MSISDN和IMSI对应关系表,如果对应关系表中存在被叫的MSISDN号码,则可以得到该号码对应的IMSI信息,向发送请求消息的主叫移动台发送呼叫请求确认消息;否则,如果基站所存储的MSISDN和IMSI对应关系表中没有该MSISDN号码,则直接给主叫移动台发送呼叫业务请求拒绝消息,结束流程。 Step 202, the base station receives a layer three-point service request message, in the message to the called subscriber's MSISDN number query local MSISDN and IMSI correspondence table, if the corresponding MSISDN number of the called presence of relational tables, it is possible to obtain the number corresponding to the IMSI information, the calling mobile station request message to the sender transmits a call request acknowledgment message; otherwise, if the base station of the stored MSISDN and IMSI correspondence table is not the MSISDN number, directly sends a call service request rejection to the calling mobile station news, the end of the process. 步骤203,基站发起寻呼过程,即向基站所有服务小区的移动台广播携带有被叫IMSI信息的寻呼消息,并启动孤站运行模式寻呼响应定时器。 Step 203, the base station initiates a paging procedure, namely a mobile station broadcasting station all serving cells carrying the called IMSI information of the paging message, and initiates a lone stations operating mode paging response timer. 步骤204,移动台收到寻呼消息后,对消息中携带的IMSI进行检测, 判断该IMSI是否为本移动台的IMSI,如果是,则移动台完成信道接入后向基站发送寻呼响应,进入步骤205;否则,如果移动台检测到该寻呼消息不是针对本移动台,则移动台不作任何响应。 Step 204, after the mobile station receives the paging message, the message carries the IMSI is detected, determines the IMSI whether the mobile station IMSI present, sends a paging response to the base station If yes, then the mobile station to complete the channel access, proceeds to step 205; otherwise, if the mobile station detects the paging message is not for this mobile station, the mobile station does not make any response. 其中,这里移动台发送寻呼响应前的信道接入过程与现有GSM系统规定的过程相同.步骤205,该被叫移动台向网络侧进一步发送携带有本移动台IMSI的寻呼响应业务请求消息。 Wherein, where the mobile same procedure channel access procedure before the station sends a paging response to a predetermined with existing GSM system. Step 205, the called mobile station further transmits to the network side carrying the present mobile station IMSI paging response to the service request messages.

步骤206,基站收到被叫移动台发来的寻呼响应业务请求消息后,通过该被叫提供的IMSI信息,并结合主叫提供的被叫MSISDN信息以及本地存储的MSISDN和IMSI对应关系表,确定请求与该被叫建立呼叫连接的主叫, 即基站在MSISDN和IMSI对应关系表中反向查找当前被叫IMSI对应的被叫MSISDN,再根据该被叫的MSISDN找到需要与其建立连接的主叫;在此以后,基站给主叫和被叫分配业务信道。 Step 206, the base station receives the called mobile station sent the paging response IMSI information of the service request message, by which the called party provides, in combination with the called MSISDN information and the locally stored MSISDN caller provided and IMSI correspondence table , determining that the request to establish the caller's call connection to the called party, i.e., the base station MSISDN and IMSI correspondence table in a reverse lookup currently called IMSI of the called number MSISDN, and then to find the called MSISDN of the need to connect to it to calling; after this, the base station to the caller and the called party assigns a traffic channel. 其中,此时,主叫业务信道和被叫业务信道一定要釆用相同的信道模式, 如果主叫移动台和被叫移动台在信道接入阶段采用的是现有技术的极早指配规程,则基站给主叫和被叫分配业务信道时,执行模式修改规程。 Wherein, at this time, calling service channel and a called traffic channel must preclude the use of the same channel mode, if the calling mobile station and a called mobile station to use the channel access phase is very early assignment procedure prior art when, the base station to the calling and called traffic channel is assigned, execution mode modify procedure. 步骤207,基站完成主叫上行信道到被叫下行信道,以及主叫下行信道到被叫上行信道的接续。 Step 207, the base station is completed calling uplink channel to the called downlink channel, and calling a downlink channel to connecting the called uplink channel. 其中,如果上、下行信道接续是在Abis接口进行,则基站需要完成对Abis接口上、下行信道不对称性的处理,具体处理方式依赖与基站厂商的具体实现规定。 Wherein, if the downlink channel connection is an interface in Abis, the base station need to complete on the Abis interface, asymmetry of downlink channel processing, specific processing-dependent manner with the base station vendor specific implementation requirements. 步骤208,基站完成接续后,给主叫移动台和被叫移动台发送CONNECT 消息,通知该两个移动台接续成功;主叫移动台和被叫移动台收到该消息后, 可以给出可闻的提示,指示主叫和被叫用户可以开始讲话。 Step 208, after the base station is completed connection, to the calling mobile station and a called mobile station sends the CONNECT message to notify the two mobile stations subsequent successful; after the originating mobile station and a called mobile station receives the message, it can compute Wen tips, indicating the calling and the called user can begin speaking. 如果在孤站运行模式寻呼响应定时器超时后,基站仍没有收到被叫移动台返回的寻呼响应,则基站给主叫移动台发送呼叫请求拒绝消息。 If the paging response timer expires solitary station mode of operation, the base station does not receive the called mobile paging response station returns the base station to the calling mobile station sends a call request rejection message. 本领域技术人员不难看出,本发明不应仅局限于GSM数字集群系统, 还可以同样适用于如:GSM公网等其它类似数字蜂窝系统,或其它类似情况。 Those skilled in the art will readily be seen that the present invention should not be limited to GSM digital trunking system, may also be equally applicable to such as: GSM public network, and other similar digital cellular systems, or other similar circumstances. 以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。 The above preferred embodiments of the present invention only but are not intended to limit the present invention, any modifications within the spirit and principle of the present invention, the, equivalent replacement, or improvement, should be included in the present invention. within the scope of protection.
