Description

用户信息通知方法及移动业务交换中心
技术领域
本发明涉及通信技术领域, 尤其涉及一种用户信息通知方法及移动业 务交换中心。 背景技术
在第三代合作伙伴计划 (The 3rd Generation Partnership Project, 简称 3GPP )42068 , 3GPP 43068, 3GPP 44068协议中定义组呼 VGCS(voice group call service, 简称 VGCS ) ) , VGCS可以建立到属于某一给定服务区 (组 呼区域) 的一组业务终端的群组语音呼叫, 呼叫采用半双工模式。 呼叫期 间任何业务终端的用户都可以成为讲者 (即讲话者) , 但任一时刻只允许 一个业务终端的用户讲话, 其他业务终端的用户为听者。
组呼在建立业务终端的群组呼叫时, 还可以同时建立到调度终端的专 有连接, 该连接采用全双工模式, 调度终端的调度员可以随时接收组呼的 语音信息, 也可以随时向整个组发布语音信息。
如果组呼区域跨越多个移动业务交换中心 (Mobile Service Switching
Center,简称 MSC),则需要指定其中某一个 MSC为锚定 MSC (ANCHOR MSC, 下述称为 MSC-A) , 其他的 MSC称为中继 MSC (RELAY MSC, 下述称为 MSC-R) 。
通常,呼叫的建立和释放,调度终端的接入均由 MSC-A处理, MSC-R 仅负责建立本 MSC下小区的组呼通道, 并向 MSC-A传递本 MSC下小区 中业务终端的组呼信令。
组呼可以由业务终端发起, 也可以由在组呼寄存器 (Group Call
Register , 简称 GCR) 中签约了组呼发起权限的调度终端发起。
在现有技术的 3GPP 43068中,业务终端在组呼中占用上行讲话时(例 如,基站子系统(Base Station Subsystem,简称 BSS )向 MSC上报 UPLINK_
REQ_CONF (L3msg)消息) , 直到释放上行停止讲话之前 (如, BSS 向 MSC上报 UPLINK RELEASE IND消息) ; 或者, 业务终端在 MSC-R占 用上行向 MSC-A发送占用上行用户信息后 (如, MSC-R向 MSC-A发送 PROCESS GROUP CALL_SIGN.(add_info)消息) , 直到释放上行停止讲话 之前(如, MSC-R向 MSC-A发送 PROCESS_GROUP CALL_SIGN. (uplink release indication)消息) , 调度终端除了讲者即占用上行资源的业务终端 的语音, 调度员无法知道得知当前是那个业务终端为当前的讲者。 发明内容

为了方便理解本发明实施例中技术方案, 先对与本发明相关的内容进 行简单说明。
本发明实施例的部分描述中调度员可指的调度员所对应的调度终端, 业务用户可指业务用户所对应的业务终端。
调度终端 (Dispatcher) : 每个组呼都可以在 GCR中签约最多 5个调 度终端。 调度终端可以是固定用户的终端或移动用户的终端, 通过网络为 其建立的专有通道参与组呼的语音通信。
业务终端 (Service Subscriber) : 在归属位置寄存器 ( Home Location Register, 简称 HLR) 中签约组呼业务的移动用户终端, 每个业务终端都 可以同时签约最多 50个组呼。 业务终端通过组呼区域内每个小区分配的 组呼通道参与组呼的语音通信。业务终端可以在 MSC-A或者 MSC-R下发 起 /结束组呼。
组呼中的锚定 MSC(MSC-A) :负责管理和维护一个特定组呼的 MSC。 当一个组呼的组呼区域超过一个 MSC时,这个组呼的锚定 MSC在网络内 预先定义。
组呼中的中继 MSC (MSC-R) : 组呼区域超过一个 MSC的区域时, 管理除归属于组呼锚定 MSC以外的小区的 MSC叫做组呼中继 MSC。
应说明,在本发明实施例中,业务终端、调度终端可以是移动电话(或 称为"蜂窝"电话) 、 具有移动终端的计算机等, 例如, 终端还可以是便携 式、 袖珍式、 手持式、 计算机内置的或者车载的移动装置。
结合图 1和图 2来说, 现有技术中, 图 1示出的是业务终端在组呼中 占用上行讲话, 且延续到释放上行停止讲话之前的流程示意图。
图 2示出的是业务终端在 MSC-R占用上行资源并向 MSC-A发送占用 上行用户信息后 (例如 MSC-R 向 MSC-A 发送 PROCESS GROUP CALL_SIGN.(add_info)消息),直到释放上行资源并停止讲话之前(MSC-R 向 MSC-A发送 PROCESS_GROUP CALL—SIGN. (uplink release indication) 消息) 的流程示意图。
在图 1和图 2中, 交互消息简单介绍如下。
上行空闲消息 (UPLINK_FREE) : BSS在主信令连接 (FACCH) 上 向移动台 (Mobile Station, 简称 MS ) 重复发送这个无连接的 RR消息, 通知所有组的成员终端上行空闲。
上行接入消息 (UPLINK_ACCESS ) : MS 使用随机接入过程在组呼 信道上行上向 BSS发送这条消息, 可以重复发送。 UPLINK_ACCESS消 息与 channel request类似, UPLINK_ACCESS是在组呼信道上行上发送, 且发送 UPLINK_ACCESS 消息的目的与后续讲者上行请求的建立原因相 同。
上行占用请求消息(UPLINK_REQUEST) : BSS向 MSC-A指示上行 请求。 一个 BSS收到多个 UPLINK_ACCESS时, 只向 MSC-A转发一个 UPLINK—REQUEST。
组呼上行允许消息 (VGCS_UPLINK_GRANT) : 在组呼信道下行上 响应上行请求,包含 MS用来向网络同步的信息和上行接入竞争解决信息, 也就是一个请求参数 (与 UPLINK_ACCESS 相关) 和物理信息 (在组呼 信道上行发送信息使用) 。 收到 VGCS_UPLINK_GRANT后, 相关的 MS 可以开始直接发送语音。 此时立即停止发送 UPLINK_FREE消息。
上行忙消息 (UPLINK_BUSY) : 在主信令连接 (FACCH) 上发送这 个无连接的 RR消息, 通知所有组的成员 MS上行忙。 如果网络支持讲者 优先级, UPLINK_BUSY向所有的听者业务终端指示当前业务终端的讲者 优先级。 如果网络设置了紧急模式, UPLINK_BUSY 也指示紧急模式。 UPLINK_BUSY 消息以 T1 秒为周期在 FACCH 上重复发送。 UPLINK_BUSY消息和下述的层二建立消息 (SABM消息) 的顺序是相互 独立的。
层二建立消息 (SABM(L3msg)) : MS向 BSS建立层二连接, 并且包 含层三信息 classmark和终端标识如 MS的标识。
层二建立确认消息 (UA(L3msg)) : BSS向 MS确认层二连接, 为竞 争解决包含与 SABM相同的层三信息。
上行占用允许消息 UPLINK_REQUEST_ACKNOWLEDGE): MSC-A 向一个 BSS确认上行占用请求消息。如果有多个 BSS或 MSC-R请求上行 占用请求消息, MSC-A采用 UPLINK_REJECT_CMD消息拒绝其他所有的 上行占用请求, 只接受一个。 BSS收到 UPLINK_REJECT_CMD消息后, 向相应的终端 /MS 发送 UPLINK_REL 消息, 再广播一个上行忙消息 (UPLINK_BUSY 消息) 指示上行忙。 MSC-A 要向所有其他没有申请上 行 占用请求 的 BSS 发送 UPLINK_SEIZED_CMD 消 息 。 收到 UPLINK_SEIZED_CMD 消息后 , BSC 要广播一个上行忙消息 (UPLINK_BUSY) 消息指示上行忙。
组呼信令转发消息( FORWARD_GROUP CALL_SIGNALLING (uplink seized command) ) : MSC-A向所有的 MSC-R发送这条消息,通知上行忙。
上行占用确认消息(UPLINK_REQUEST_CONFIRM) : BSS向 MSC-A 确认上行的使用, 携带终端标识。
在 RANFlex 配置下, 请求上行用户的受访的移动交换中心 (visited mobile switching center, 简称 VMSC ) 可能与其所在位置区的组呼服务 MSC 不 同 , 在 这 种 情 况 下 , VMSC 要 使 用 MAP 消 息 SEND_GROUP_CALL_INFO到服务 MSC的 VLR获取信息如用户信息。
用户信息下发消息 (VGCS_ADD_INFO ) : MSC-A向所有的 BSS发 送新讲者业务终端的额外信息。然后 BSS向所有听者广播包含额外信息的 ADD—INFO消息。
组呼信令转发消息 ( FORWARD_GROUP CALL_SIGNALLING (additional info) ) : MSC-A向所有的 MSC-R发送这条消息, 提供新讲者 业务终端的额外信息。
会话过程 (Conversation proceeds ) : 一旦终端 /MS控制了上行, 就可 以直接通信。 会议桥的双向属性能够保证已经连接了所有的下行信道。
上行释放消息 (UPLINK_RELEASE ) : 当拥有上行资源的业务终端 打算释放上行资源时,拥有上行资源的业务终端在 FACCH上向 BSS发送 这条消息指示释放上行。
上行释放指示消息 (UPLINK_RELEASE_INDICATION) : BSS通知 MSC-A对上行进行释放。
组呼信令转发消息( FORWARD—GROUP CALL_SIGNALLING (uplink release indication) ) : MSC-A通知所有的 MSC-R上行空闲。 然后 MSC-R 向每一个相关的 BSS发送 UPLINK RELEASE消息指示上行空闲。
此外, 在图 2中与图 1中相同的消息不再详述, 仅说明图 2中与图 1 中不相同的消息。
上行占用请求消息 (UPLINK_REQUEST) : BSS 向 MSC-R指示上行 请求。 一个 BSC 收到多个上行接入请求 (UPLINK_ACCESS ) 时, 只向 MSC-R转发一个 UPLINK_REQUEST。
BSS 支持讲者优先级并且从终端收到一个高于 "normal subscriber"的 讲者优先级时, BSS要延迟向 MSC发送 UPLINK_REQUEST消息, 直到 收到终端发来的包含终端标识的 SABM(L3msg)。 然后 BSS 在 UPLINK_REQUEST消息中包含层三消息、 讲者优先级、 小区标识 (收到 UPLINK_ACCESS 消息的小区) 。 在这种情况下, BSS 不发送 UPLINK—REQUEST—CONFIRM消息。
组呼信令请求消息 (PROCESS_GROUP CALL_SIGNALLING (uplink request) ) : MSC-R向 MSC-A发送这条消息, 指示有漫游在 MSC-R内的 业务终端请求上行资源。
如果在 UPLINK_REQUEST消息中包含层三消息,则如果能够得到的 话, 在 PROCESS_GROUP CALL_SIGNALLING消息中还要包含新讲者业 务终端的额外信息。
组呼信令转发消息( FORWARD—GROUP CALL_SIGNALLING (uplink request ack) ) : MSC-A向 MSC-R发送这条消息,指示允许了漫游在 MSC-R 内的业务终端的上行请求。
上行占用允许消息(UPLINK_REQUEST_ACKNOWLEDGE): MSC-R 向 一个 BSS 确认上行 。 如果有多个 BSS 请求上行 , 用 UPLINK_REJECT_CMD消息拒绝其他所有的上行请求,只接受一个。 BSS 收到 UPLINK_REJECT_CMD 消息后, 向相应的终端发送 UPLINK_REL 消息, 再广播一个 UPLINK_BUSY消息指示上行忙。 MSC-R要向所有其 他没有申请上行的 BSS 发送 UPLINK_SEIZED_CMD 消息。 收到 UPLINK_SEIZED_CMD消息后, BSS要广播一个 UPLINK_BUSY消息指 示上行忙。
上行占用确认消息(UPLINK_REQUEST_CONFIRM): BSS向 MSC-R 确认上行的使用, 携带终端标识。
在 RANFlex配置下, 请求上行用户的 VMSC可能与其所在位置区的 组呼服务 MSC 不同, 在这种情况下, VMSC 要使用 MAP 消息 SEND_GROUP_CALL_INFO到服务 MSC的 VLR获取信息。
VGCS_ADD_INFO: MSC-R向所有的 BSS发送新讲者业务终端的额 外信息。 然后 BSS向所有听者广播包含额外信息的 ADD_INFO消息。
组呼信令请求消息 ( PROCESS_GROUP CALL_SIGNALLING (additional info) ) : MSC-R向 MSC-A发送这条消息, 提供新讲者业务终端 的额外信息。 MSC-A要向所有的其他 MSC-R转发这个消息。
如果额外信息已经包含在 PROCESS_GROUP CALL_SIGNALLING (uplink request)消息中了, 就不发送这条消息。
会话过程 (Conversation proceeds ) : 一旦终端控制了上行, 就可以直 接通信。 会议桥的双向属性能够保证已经连接了所有的下行信道。 上行释放消息 (UPLINK_RELEASE ) : 当拥有上行资源的业务终端 打算释放上行资源时,业务终端在 FACCH上向 BSS发送这条消息指示释 放上行。
上行释放指示消息 (UPLINK_RELEASE_INDICATION) : BSS通知 MSC-R上行释放。
组呼信令请求消息 (PROCESS_GROUP CALL_SIGNALLING (uplink release indication) ) : MSC-R向 MSC-A指示上行空闲。
在上述图 1 和图 2 中的组呼中业务终端占用上行一直到释放上行之 间, 该讲者的用户信息没有发送给调度终端, 由此, 调度终端无法直接从 信息交互中获取讲者的用户信息。
本发明实施例提供一种用户信息通知的方法, 该方法包括:
若组呼中业务终端在移动业务交换中心 MSC 下占用上行资源, 则 MSC 获取到所述业务终端的用户信息之后, 向所述调度终端发送第一消 息, 所述第一消息中携带占用上行资源的业务终端的用户信息。
本实施例的用户信息通知方法, 通过 MSC获取到业务终端的用户信 息之后, 将获取的业务终端的用户信息发送至调度终端, 以使组呼中调度 终端能够获知占用上行资源的业务终端的用户信息。
举例来说, 所述用户信息包括下述信息中的一项或多项:
终端标识、 用户优先级、 用户的位置信息和功能号码等。
结合图 3A和图 3B所示, 图 3A和图 3B示出了本发明一实施例提供 的用户信息通知方法的流程示意图, 本实施例中的用户信息通知方法如下 所述。
101、 若组呼中业务终端在 MSC-A下占用上行资源, 则所述 MSC-A 在接收到 BSS上报的上行资源占用确认消息后,根据所述上行资源占用确 认消息获得所述业务终端的用户信息。
当前, 所述上行资源占用确认消息包括: 占用上行资源的业务终端的 用户信息, 由此, 在 MSC-A接收 BSS上报的上行资源占用确认消息 (如 UPLINK_ REQ_CONF消息) 之后, 即可获得业务终端的用户信息。
102、 MSC在获取到所述业务终端的用户信息之后, 向所述调度终端 发送第一消息, 所述第一消息中携带占用上行资源的业务终端的用户信 举例来说, 所述第一消息可为用户信息指示消息, 如用户到用户信令
3 (User to User Signaling 3, 简称 UUS3 )业务中的 USER INFORMATION 消息。
可选地, 在图 3A所示的基础上, 上述用户信息通知方法还可包括下 述的步骤 103, 如图 3B所示。
103、 若业务终端释放所述上行资源, 则所述 MSC在接收上行资源释 放指示消息之后, 向所述调度终端发送第二消息, 所述第二消息中携带所 述释放占用上行资源的业务终端的用户信息。
举例来说, 第二消息可为用户信息指示消息, 例如, UUS3业务里的
USER INFORMATION消息。
在图 3B 中, 前述的上行资源释放指示消息可为 BSS 向所述 MSC-A 发送的; 也就是说, 组呼中业务终端在 MSC-A下占用上行资源, 所述上 行资源释放指示消息为 BSS向所述 MSC-A发送的。
在图 3B所示的组呼流程图中, 某一业务终端 (如 MS ) 在 MSC-A下 占用上行资源讲话, BSS 给 MSC上报 UPLINK_ REQ_CONF消息后,
MSC-A获取到业务终端的用户信息, 进而 MSC-A向调度终端发送 USER
INFORMATION消息, 把业务终端的用户信息通知给调度终端。
可选地, 在业务终端释放上行资源时, BSS 给 MSC-A 上报 UPLINK_RELEASE_I消息后或者 MSC-A释放上行资源时, MSC-A向调 度终端发送 USER INFORMATION消息,把业务终端的用户信息通知给调 度终端。 可以理解的是, 此时 MSC-A将释放上行资源的业务终端的用户 信息告知调度终端, 以使得调度终端获知当前没有业务终端占用上行资 源。
在本实施例中的第一消息和第二消息可以相同, 用于表示同一业务终 端对上行资源的占用和释放。 在其他实施例中, 前述的第一消息和第二消 息可以不同, 其可以根据实际需要设置, 本实施例仅为举例说明。
上述用户信息通知方法可以使得组呼中调度终端获知占用上行资源 的业务终端的用户信息。
此外, 需要说明的是, 在实际应用中, 若 MSC-A在业务终端占用上 行资源预设时间之后, 主动释放所述业务终端占用的上行资源时, 可向调 度终端发送第二消息, 所述第二消息中携带所述释放占用上行资源的业务 终端的用户信息。
也就是说, MSC-A无论是否接收到 BSS发送的上行资源释放指示消 息, 在业务终端占用上行资源一定时间之后, 释放业务终端所占用的上行 资源时, 可向调度终端发送第二消息。
结合图 4A和图 4B所示, 图 4A和图 4B示出了本发明一实施例提供 的用户信息通知方法的流程示意图, 本实施例中的用户信息通知方法如下 所述。
201、 若组呼中业务终端在 MSC-R下占用上行资源, 则所述 MSC-A 在接收到 MSC-R发送的组呼信令请求消息后, 根据所述组呼信令请求消 息获得所述业务终端的用户信息。
举例来说, 组呼信令请求消息包括: 占用上行资源的业务终端的用户 信息。
202、 MSC在获取到所述业务终端的用户信息之后, 向所述调度终端 发送第一消息, 所述第一消息中携带占用上行资源的业务终端的用户信 息。
举例来说,第一消息还可为 UUS3业务中的 USER INFORMATION消 息。
203、 若业务终端释放所述上行资源, 则所述 MSC在接收上行资源释 放指示消息之后, 向所述调度终端发送第二消息, 所述第二消息中携带所 述释放占用上行资源的业务终端的用户信息。
第二消息可为 UUS3业务中的 USER INFORMATION消息。 应说明, 在本实施例中, 第一消息和第二消息可以相同, 该第二消息用于告知调度 终端当前没有业务终端占用上行资源, 即占用上行资源的业务终端已经释 放所占用的上行资源。 当然, 在其他实施例中, 也可以使第一消息和第二 消息不相同。
可选地, 图 4B中显示组呼中业务终端在 MSC-R下占用上行资源, 则 所述上行资源释放指示消息可为 MSC-R向所述 MSC-A发送的。
在图 4B所示的组呼流程图中, MSC-R下的业务终端占用上行资源, MSC-R给 MSC-A发送 PROCESS GROUP CALL_SIGN消息后, MSC-A 使用 UUS3业务里的 USER INFORMATION消息,把占用上行资源的业务 终端的用户信息通知给调度终端。
可选地,在 MSC-R下的业务终端释放上行资源时, MSC-R给 MSC-A 发送 PROCESS_GROUP CALL_SIGN.(uplink release indication)消息后或者 MSC-A 释放上行资源时, MSC-A 使用 UUS3 业务中的 USER INFORMATION消息,把占用上行资源的业务终端的用户信息通知给调度 终端。
在本实施例中, MSC-A 在业务终端占用上行资源预设时间之后, 主 动释放所述业务终端占用的上行资源时, 可向调度终端发送第二消息, 所 述第二消息中携带所述释放占用上行资源的业务终端的用户信息。
也就是说, MSC-A无论是否接收到 MSC-R送的上行资源释放指示消 息, 在业务终端占用上行资源一定时间之后, 主动释放业务终端所占用的 上行资源时, 可向调度终端发送第二消息。
上述用户信息通知方法可以使得组呼中调度终端获知占用上行资源 的业务终端的用户信息。

其中, 处理器 51用于组呼中业务终端在 MSC下占用上行资源时, 获 取所述业务终端的用户信息;
发射器 52用于在所述处理器 51 获取到所述业务终端的用户信息之 后, 向所述调度终端发送第一消息, 所述第一消息中携带占用上行资源的 业务终端的用户信息。
举例来说, 所述用户信息包括下述信息中的一项或多项:
终端标识、 用户优先级、 用户的位置信息和功能号码。
在一种可选的实现场景中, 所述处理器 51具体用于,
组呼中业务终端在 MSC-A下占用上行资源时, 接收 BSS上报的上行 资源占用确认消息, 并根据所述上行资源占用确认消息获得所述业务终端 的用户信息。 在本实施例中, 前述的上行资源占用确认消息包括: 占用上行资源的 业务终端的用户信息。
在第二种可选的实现场景中, 所述处理器 51具体用于,
组呼中业务终端在 MSC-R下占用上行资源时,接收 MSC-R发送的组 呼信令请求消息, 并根据所述组呼信令请求消息获得所述业务终端的用户 信息。
在本实施例中, 所述组呼信令请求消息包括: 占用上行资源的业务终 端的用户信息。
在第三种可选的实现场景中, 所述处理器 51 还用于, 在业务终端释 放所述上行资源时, 接收上行资源释放指示消息;
相应地, 所述发射器 52还用于, 在所述处理器 51接收所述上行资源 释放指示消息之后, 向所述调度终端发送第二消息, 所述第二消息中携带 所述释放占用上行资源的业务终端的用户信息。
举例来说, 在第三种可选的实现场景中, 前述的处理器 51 可具体用 于, 组呼中业务终端在 MSC-A下占用上行资源时, 接收 BSS发送的上行 资源释放指示消息;
或者, 前述的处理器 51可具体用于, 组呼中业务终端在 MSC-R下占 用上行资源时, 接收 MSC-R发送的上行资源释放消息。
