多频段网络中寻呼终端的方法、 装置和基站子系统 本申请要求于 2011 年 2 月 24 日提交中国专利局、 申请号为 201110045390.0、 发明名称为 "多频段网络中寻呼终端的方法、 装置和基站 子系统" 的中国专利申请的优先权, 其全部内容通过引用结合在本申请中。 技术领域 本发明实施例涉及通信技术领域, 尤其涉及一种多频段网络中寻呼终 端的方法、 装置和基站子系统。 背景技术 在通信市场中, 越来越多的运营商寻求合并来提高竟争力。 由于不同 的运营商一般有不同的频段, 于是就产生了多频段叠加组网的场景, 即多 频段网络。 另外, 在人口密集、 话务量很大的城市, 也需要多个频段叠加 组网, 才能有足够的容量。
多频段叠加组网的场景中, 按照对频段的支持情况, 可以将终端分为 单频段终端和多频段终端; 其中单频段终端只支持一个频段, 多频段终端 可以支持多个频段。对于单频段终端,基站子系统( Base Station Subsystem, 以下简称为: BSS )可以存储该终端支持的频段, 然后 BSS在寻呼时根据 存储的频段确定该终端守候的频点。 但是对于多频段终端, BSS 无法准确 知道终端当前守候的频段, 原因如下: ( 1 )一般多频段终端首先搜索 PRL 中设置的优选频点,锁定频点后根据频点信道列表确定守候的频点,而 PRL 一般在出厂或者出售时设定, 网络侧 (即 BSS )没有 PRL中的信息; (2 ) 多频终端在移动过程中, 走到频点覆盖的盲点后, 终端会重选系统到其他 频段, 锁定频点后, 终端开始守候到新的频段, 而对此过程, BSS 并不知 晓。
由于 BSS无法准确知道多频段终端当前守候的频段, 为了寻呼到多频 终端, 在现有的多频段网络中寻呼多频终端时, BSS 在终端支持的每个频 段都要 Hash—个频点进行寻呼。 由此, 多频段网络中的寻呼量远大于单频 段网络中的寻呼量, 从而导致网络容量的浪费, 并且造成寻呼精度较差。 发明内容 本发明实施例提供一种多频段网络中寻呼终端的方法、 装置和基站子 系统, 用以在多频段网络中精确寻呼终端, 并降低对网络容量的消耗。

本发明实施例提供一种多频段网络中寻呼终端的装置, 包括: 重定向广播发送模块, 用于根据预置规则, 发送业务重定向广播消息, 以使终端根据所述业务重定向广播消息重定向所述终端对应的频段;
能力获取模块, 用于获取终端的频段支持能力, 所述频段支持能力为 终端支持的频段信息;
频段获取模块, 用于若所述能力获取模块获取所述终端为多频段终端, 则根据所述预置规则获取所述终端对应的频段;
第一寻呼模块, 用于在所述频段获取模块获取到的所述终端对应的频 段上进行寻呼。
本发明实施例提供一种基站子系统, 包括本发明实施例提供的任一多 频段网络中寻呼终端的装置。
本发明实施例的多频段网络中寻呼终端的方法、 装置和基站子系统, 基站子系统根据预置规则发送业务重定向广播消息, 使得终端根据该业务 重定向广播消息重定向该终端对应的频段; 基站子系统获取终端的频段支 持能力, 然后基站子系统根据预置规则获取多频段终端对应的频段, 并在 获取的频段上对终端进行寻呼。 由于基站子系统根据预置规则向终端发送 重定向的广播消息, 所以对于某一多频段终端, 基站子系统根据该规则即 可判断出该终端对应的重定向的频段, 由此基站子系统就可以在该频段对 该终端进行寻呼, 从而可以实现对终端的精确寻呼、 降低对网络容量的消 耗。 附图说明 为了更清楚地说明本发明实施例中的技术方案, 下面将对实施例描述 中所需要使用的附图作一简单地介绍, 显而易见地, 下面描述中的附图是 本发明的一些实施例, 对于本领域普通技术人员来讲, 在不付出创造性劳 动的前提下, 还可以根据这些附图获得其他的附图。

图 1为本发明多频段网络中寻呼终端的方法实施例一的流程图,如图 1 所示, 该方法包括:
步骤 101、 根据预置规则, 发送业务重定向广播消息, 以使终端根据业 务重定向广播消息重定向终端对应的频段。
本发明实施例可以应用于多频段网络中, 本实施例的执行主体为基站 子系统( Base Station Subsystem, 以下简称为: BSS ) 。
BSS根据预置规则发送业务重定向广播消息, 使得该 BSS服务的各个 终端接收到该业务重定向广播消息后, 可以进行业务重定向, 将该终端对 应的频段进行重定向。 例如, 该多频段网络中包括 k个频段, 该规则可以 把 BSS服务的所有终端分为 k组, 然后将每一组的终端对应的频段重定向 到一个频段, 由此使得 k组终端分别对应 k个频段。
多频段终端接收到 BSS发送的业务重定向广播消息后, 根据该广播消 息中的规则, 将自身对应的频段进行重定向, 以符合该规则的规定。 对于 单频段终端, 由于该终端只能支持一个频段, 所以无法根据该广播消息进 行频段的重定向。
步骤 102、获取终端的频段支持能力; 频段支持能力为终端支持的频段 信息。
当 BSS要寻呼一个终端时, BSS先获取终端的频段支持能力。 其中, 该频段支持能力表示终端支持的频段信息。 若一终端只支持一个频段, 则 该终端为单频段终端; 若一终端支持的频段大于一个, 则该终端为多频段 终端。
BSS可以从移动交换中心( Mobile Switching Center,以下简称为: MSC ) 上获取到终端的频段支持能力, 也可以在公共信道上对终端的频段支持能 力进行查询。
步骤 103、若终端为多频段终端,则根据预置规则获取终端对应的频段。 当 BSS获取到待寻呼的终端为多频段终端时, BSS根据上述预置规则, 可以获取该终端属于哪一组, 进而获取到该终端对应哪一个频段。 步骤 104、 在获取到的终端对应的频段上进行寻呼。
BSS根据业务重定向广播消息中的规则, 获取该终端对应的频段后, 在该频段上对该终端进行寻呼。
若 BSS获取到待寻呼的终端为单频段终端, 则 BSS直接在该终端对应 的频段上进行寻呼。
本发明实施例, BSS 根据预置规则发送业务重定向广播消息, 使得终 端根据该业务重定向广播消息重定向该终端对应的频段; BSS 获取终端的 频段支持能力, 然后 BSS根据预置规则获取多频段终端对应的频段, 并在 获取的频段上对终端进行寻呼。 由于 BSS根据预置规则向终端发送重定向 的广播消息, 所以对于某一多频段终端, BSS根据该规则即可判断出该终 端对应的重定向的频段, 由此 BSS就可以在该频段对该终端进行寻呼, 从 而可以实现对终端的精确寻呼、 降低对网络容量的消耗。 图 2为本发明多频段网络中寻呼终端的方法实施例二的流程图,如图 2 所示, 该方法包括:
步骤 201、 BSS根据预置规则发送业务重定向广播消息。
本发明实施例可以应用于多频段网络中。
其中, 该预置规则可以为: 该多频段网络包括 k个频段, k大于 1 , 该 多频段网络中的终端分为 k组, 且 k组多频段网络分别对应 k个频段。 具 体的, 本步骤可以为: 在第 i个频段上, BSS发送用于指示除第 i组以外的 k-1组终端分别重定向到除第 i个频段以外的 k-1个频段上的业务重定向广 播消息; 其中, l i k。
BSS可以在空闲态时, 定时发送业务重定向广播消息, 具体的 BSS可 以使用广播方式发送全局业务重定向消息 (EGSRDM ) 。
需要说明的是, 该预置规则可以根据组网的需求来灵活配置, 也可以 根据每个频段中频点个数占总频点个数的比例来配置该预置规则。 根据每 个频段中频点个数占总频点个数的比例配置的预置规则可以为: 该多频段 网络包括 k个频段, k大于 1 ; 按照 IMSI的末位数字的数值和各个频段中 的频点个数占总频点个数的比例, 将该多频段网络中的终端分为 k组, 且 第 i组中包含的终端的数量占终端总数量的比例与第 i个频段中的频点个数 占总频点个数的比例相同。
例如: 多频段网络包括 450M频段和 800M频段, 800M频段的频点个 数为 4, 450M频段的频点个数为 1 , 即 800M频段的频点个数占总频点个 数的 80%, 800M频段容量是 450M频段容量的 4倍; 由此将该多频段网络 中的终端分为两组, 一组中的终端的数量是另一组中的终端的数量的 4倍, 例如: 将 IMSI的末位数字为 1/2/3/4/6/7/8/9的终端重定向到 800M频段上, 将 IMSI的末位数字为 0/5的终端重定向到 450M频段上; 即将 80%的终端 重定向到 800M频段, 将 20%的终端重定向到 450M频段。 根据 IMSI的分 配,可以认为 IMSI的末位数字为 0/5的终端占总数的 20%, IMSI的末位数 字为 1/2/3/4/6/7/8/9的终端占总数的 80%。
上述预置规则确定后, 即确定将 IMSI的末位数字为 1/2/3/4/6/7/8/9的 终端重定向到 800M频段上, 将 IMSI的末位数字为 0/5 的终端重定向到 450M频段上之后, BSS在 800M频段上, 发送用于指示 IMSI的末位数字 为 0/5的终端重定向到 450M频段上的业务重定向广播消息, BSS在 450M 频段上, 发送用于指示 IMSI的末位数字为 1/2/3/4/6/7/8/9的终端重定向到 800M频段上的业务重定向广播消息。
通过业务重定向, 可以实现跨频段的空闲态负荷均衡。
步骤 202、 终端根据业务重定向广播消息重定向终端对应的频段。
终端接收到业务重定向广播消息后, 根据该消息, 将该终端对应的频 段进行重定向。 根据步骤 201终端举例, 原来在 450M频段上的 IMSI的末 位数字为 1/2/3/4/6/7/8/9的终端, 将其对应的频段重定向到 800M频段, 原 来在 800M频段上的 IMSI的末位数字为 0/5的终端将其对应的频段重定向 到 450M频段。
步骤 203、 BSS获取终端的频段支持能力。 若该终端为多频段终端, 则 执行步骤 204; 若该终端为单频段终端, 执行步骤 206。
BSS可以从 MSC中获取终端的频段支持能力。 MSC在终端登记(例 如可以包含时间登记、 位置区登记和开关机登记) 时, 可以记录该终端的 频段支持能力; 或者 MSC在终端登记时, 查询该终端的频段支持能力。 然 后 BSS就可以从 MSC中获取到终端的频段支持能力。
若 MSC中没有存储终端的频段支持能力,则 BSS在公共信道上对该终 端的频段支持能力进行查询, 并可以将查询到的该终端的频段支持能力发 送给 MSC。 具体的, 当 MSC中没有记录该终端的频段支持能力时, MSC 通过携带移动用户信息 (Mobile Subscription Information ) 字段的登记 ( Registration ) 消息触发 BSS在公共信道上完成对终端频段支持能力的查 询, 并由 BSS将查询结果通过位置更新请求( Location Updating Request ) 消息中的移动用户信息字段通知 MSC, 然后 MSC将该终端的频段支持能 力记录在移动用户信息中。
步骤 204、 BSS根据预置规则获取终端对应的频段, 并在获取到的所述 终端对应的频段上进行寻呼, 若寻呼失败, 则执行步骤 205; 若寻呼成功, 则结束。
BSS根据预置规则, 可以获取到该终端对应的频段, 即可以获取到该 终端当前驻留的频段; 然后 BSS在该频段上 HASH (哈希) 出一个频点, 并在该频点进行寻呼。
步骤 205、 BSS在终端支持的所有频段上进行寻呼。
若步骤 204中的寻呼失败, 则 BSS在终端支持的所有频段上各 HASH 出一个频点进行寻呼。
需要说明的是, 若 MSC没有获取到一终端的频段支持能力, 则对于该 终端进行寻呼时, 在该多频段网络的所有频段上各 HASH出一个频点进行 寻呼。
步骤 206、 BSS在单频段终端支持的频段上 HASH—个频点进行寻呼。 本发明实施例, BSS 根据预置规则发送业务重定向广播消息, 使得终 端根据该业务重定向广播消息重定向该终端对应的频段; BSS 获取终端的 频段支持能力, 然后 BSS根据预置规则获取多频段终端对应的频段, 并在 获取的频段上对终端进行寻呼。 由于 BSS根据预置规则向终端发送重定向 的广播消息, 所以对于某一多频段终端, BSS根据该规则即可判断出该终 端对应的重定向的频段, 由此 BSS就可以在该频段对该终端进行寻呼, 从 而可以实现对终端的精确寻呼、 降低对网络容量的消耗。 本实施例由于将 多频段终端根据各个频段的容量按比例的进行频段的重定向, 所以可以使 得网络负荷均衡;并且 BSS能够根据终端的 IMSI确定终端当前守候的频段, 从而可以对终端进行精确寻呼, 降低了系统的寻呼负荷。
