集群系统及其广播消息发送方法 技术领域 本发明涉及通信领域， 具体而言， 涉及一种集群系统及其广播消息发送 方法。 背景技术
CDMA ( Code Division Multiple Access, 码分多址） 协议规定， 寻呼信 道被划分成 80ms的寻呼时隙， 多个寻呼时隙组成一个广播周期。 广播周期 为 5 + 3个寻呼时隙， 广播周期的第一个时隙即为广播时隙。 S的计算公式如 下： ^ = 2! xl6 , 其中 为广播周期指数。 集群系统消息发送的一种重要方式是通过在寻呼信道广播周期的广播时 隙发送。 集群终端通过监听广播周期的广播时隙接收基站发送的广播消息。 例如集群系统的周期寻呼消息， 都需要利用寻呼信道广播时隙发送消息给集 群终端。 但随着集群网络的发展， 群组的不断增加， 每个群组都需要占用广 播周期的广播时隙给该群组的归属终端发送消息。 随着广播时隙消息发送量 的不断增加， 寻呼信道广播时隙已经不堪重负， 当多个群组同时呼叫时， 往 往由于广播时隙不能及时发送多个群组的广播消息， 导致消息拥塞， 网络通 信质量无法保证。 根据 CDMA2000 协议规定， 寻呼信道最大按照 9600bit/秒的速率， 每 80ms 一个时隙的划分方式， 每个时隙 （ 包括广播时隙 ） 最多发送 9600*0.08=768个比特。 寻呼信道的每个时隙最多能够发送 768个比特， 而 寻呼时隙还需要承担开销消息发送及其它一些相应的指示比特， 留给发送广 播消息的比特比 768比特还要少。 随着集群网络用户的不断增加， 群组的不 断增长， 同时呼叫的群组将以百计， 而寻呼信道广播时隙的容量有限， 如何 满足多个群组同时存在时， 广播消息在广播时隙的发送需求， 成为提高集群 系统性能急需解决的重要问题之一。 目前， 一种方法就是延长集群呼叫广播消息的发送周期， 尽量减少寻呼 信道广播消息在广播时隙的发送量， 减轻广播时隙负荷。 但是， 随着网络规 模的增加， 群组的增长， 寻呼信道广播消息还是会不断增加， 消息拥塞对集 群系统的影响再所难免， 因此， 这种方法无法从才艮本上解决满足多个群组同 时存在时广播消息在广播时隙的发送需求的问题。 同时， 集群系统对接续性 能的要求， 也不允许对广播消息做太长时间的延迟。 发明内容 本发明的主要目的在于提供一种集群系统及其广播消息发送方法， 以至 少解决上述问题。 根据本发明的一个方面， 提供了一种集群系统的广播消息发送方法， 包 括： 当判断要向终端发送的广播消息无法在一个时隙内发送完时， 基站在连 续多个时隙内发送广播消息， 并在每个的多个时隙中发送用于指示终端是否 继续监听下一个时隙的信息； 终端根据接收到的信息判断是否继续监听下一 个时隙； 当判断结果为继续监听时， 终端继续监听下一个时隙直至接收完所 要接收的所有广播消息。 优选地， 上述信息为广播寻呼消息中的第一指示字段， 当第一指示字段 的值为预定值时用于指示在广播时隙收到广播寻呼消息的终端继续监听下一 个时隙。 优选地， 当判断要向终端发送的广播消息无法在一个时隙内发送完时， 基站在连续多个时隙内发送广播消息， 并在每个的多个时隙中发送用于指示 终端是否继续监听下一个时隙的信息包括： 当判断要向终端发送的广播消息 无法在一个广播时隙内发送完时， 基站将广播寻呼消息中的第一指示字段置 为预定值； 基站将广播寻呼消息发送给终端。 优选地， 当判断结果为继续监听时， 终端继续监听下一个时隙直至接收 完所要接收的所有广播消息包括： 终端在广播时隙接收到广播寻呼消息； 终 端判断广播寻呼消息中携带的第一指示字段的值为预定值； 终端在监听广播 时隙之后继续监听广播时隙的下一个时隙， 并继续在广播时隙的下一个时隙 接收基站发送的广播消息。 优选地， 上述信息为广播寻呼消息中的第一指示字段和第二指示字段， 当第一指示字段的值为第一预定值时用于指示在广播时隙收到广播寻呼消息 的终端继续监听下一个时隙； 当第二指示字段的值为第二预定值时用于指示 在分配时隙收到广播寻呼消息的终端继续监听下一个时隙。 优选地， 当判断要向终端发送的广播消息无法在一个时隙内发送完时， 基站在连续多个时隙内发送广播消息， 并在每个的多个时隙中发送用于指示 终端是否继续监听下一个时隙的信息包括： 当判断要向终端发送的广播消息 无法在一个广播时隙内发送完时， 基站将广播寻呼消息中的第一指示字段置 为第一预定值， 并将广播寻呼消息发送给终端； 当判断要向终端发送的广播 消息无法在一个分配时隙内发送完时， 基站将广播寻呼消息中的第二指示字 段置为第二预定值， 并将广播寻呼消息发送给终端。 优选地， 终端根据接收的广播消息中的指示字段继续监听下一个时隙直 至接收完广播消息包括： 当终端在广播时隙接收到广播寻呼消息时， 终端判 断广播寻呼消息中携带的第一指示字段的值为第一预定值， 则在监听广播时 隙之后继续监听广播时隙的下一个时隙， 并继续在广播时隙的下一个时隙接 收基站发送的广播消息； 当终端在分配时隙接收到广播寻呼消息时， 终端判 断广播寻呼消息中携带的第二指示字段的值为第二预定值， 则在监听分配时 隙之后继续监听分配时隙的下一个时隙， 并继续在分配时隙的下一个时隙接 收基站发送的广播消息。 根据本发明的另一方面， 提供了一种集群系统， 包括： 基站， 用于当判 断要向终端发送的广播消息无法在一个时隙内发送完时， 在连续多个时隙内 发送广播消息， 并在每个的多个时隙中发送用于指示终端是否继续监听下一 个时隙的信息； 终端， 用于 居接收到的信息判断是否继续监听下一个时隙； 还用于当判断结果为继续监听时， 继续监听下一个时隙直至接收完所要接收 的所有广播消息。 优选地， 上述信息为广播寻呼消息中的第一指示字段， 当第一指示字段 的值为预定值时用于指示在广播时隙收到广播寻呼消息的终端继续监听下一 个时隙。 优选地， 基站包括： 设置模块， 用于当判断要向终端发送的广播消息无 法在一个广播时隙内发送完时， 将广播寻呼消息中的第一指示字段置为预定 值； 发送模块， 用于将广播寻呼消息发送给终端； 终端包括： 接收模块， 用于在广播时隙接收到广播寻呼消息； 还用于当 判断模块判断广播寻呼消息中携带的第一指示字段的值为预定值时， 在监听 广播时隙之后继续监听广播时隙的下一个时隙， 并继续在广播时隙的下一个 时隙接收基站发送的广播消息； 判断模块， 用于判断广播寻呼消息中携带的 第一指示字段的值为预定值。 通过本发明， 由于通过在集群系统的广播寻呼消息中扩展字段， 指示集 群终端是否继续监听下一个时隙， 当基站需要给集群终端发送的消息无法在 一个时隙发送完毕时， 可以使用广播寻呼消息扩展字段， 指示终端在下一个 时隙继续监听寻呼信道， 接收寻呼信道消息， 解决了相关技术无法从根本上 解决满足多个群组同时存在时广播消息在广播时隙的发送需求的问题， 从而 可以在连续的多个时隙发送寻呼信道广播消息， 终端在多个时隙上监听广播 消息， 达到提高集群系统广播消息在寻呼信道发送容量的目的。 附图说明 此处所说明的附图用来提供对本发明的进一步理解， 构成本申请的一部 分， 本发明的示意性实施例及其说明用于解释本发明， 并不构成对本发明的 不当限定。 在附图中： 图 1是根据本发明实施例的集群系统的广播消息发送方法的流程图； 图 2是 居本发明实施例的集群系统的示意图。 具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是， 在 不冲突的情况下， 本申请中的实施例及实施例中的特征可以相互组合。 图 1是根据本发明实施例的集群系统的广播消息发送方法的流程图， 包 括以下步 4聚： 步骤 S 102 , 当判断要向终端发送的广播消息无法在一个时隙内发送完 时， 基站在连续多个时隙内发送广播消息， 并在该多个时隙中的每个时限中 发送用于指示终端是否继续监听下一个时隙的信息； 步骤 S 104, 终端 居接收到的信息判断是否继续监听下一个时隙； 步骤 S 106, 当判断结果为继续监听时， 终端继续监听下一个时隙直至接 收完所要接收的所有广播消息。 该实施例通过在集群系统的广播寻呼消息中扩展字段， 指示集群终端是 否继续监听下一个时隙， 当基站需要给集群终端发送的消息无法在一个时隙 发送完毕时， 可以使用广播寻呼消息扩展字段， 指示终端在下一个时隙继续 监听寻呼信道， 接收寻呼信道消息。 解决了相关技术无法从根本上解决满足 多个群组同时存在时广播消息在广播时隙的发送需求的问题。 使用该实施例 基站可以在连续的多个时隙发送寻呼信道广播消息， 终端在多个时隙上监听 广播消息， 达到提高集群系统广播消息在寻呼信道发送容量的目的。 此外， 该实施例能够在保证集群系统接续性能的前提下， 使基站能够及 时地发送更多的广播消息， 达到提高集群系统广播消息的发送容量的目的。 优选地， 该用于指示终端是否继续监听下一个时隙的信息为广播寻呼消 息中的第一指示字段， 当该第一指示字段的值为预定值时用于指示在广播时 隙收到广播寻呼消息的终端继续监听下一个时隙。 优选地， 步 4聚 S 102 包括： 当判断要向终端发送的广播消息无法在一个 广播时隙内发送完时， 基站将广播寻呼消息中的第一指示字段置为预定值； 基站将广播寻呼消息发送给终端。 步骤 S 106 包括： 终端在广播时隙接收到广播寻呼消息； 终端判断该广 播寻呼消息中携带的第一指示字段的值为预定值； 终端在监听广播时隙之后 继续监听该广播时隙的下一个时隙， 并继续在该广播时隙的下一个时隙接收 基站发送的广播消息。 上述优选实施例提供了集群系统的广播消息发送方法的一种具体实施方 案。 优选地， 该用于指示终端是否继续监听下一个时隙的信息为广播寻呼消 息中的第一指示字段和第二指示字段， 当第一指示字段的值为第一预定值时 用于指示在广播时隙收到广播寻呼消息的终端继续监听下一个时隙； 当第二 指示字段的值为第二预定值时用于指示在分配时隙收到广播寻呼消息的终端 继续监听下一个时隙。 优选地， 步 4聚 S 102 包括： 当判断要向终端发送的广播消息无法在一个 广播时隙内发送完时， 基站将广播寻呼消息中的第一指示字段置为第一预定 值， 并将该广播寻呼消息发送给终端； 当判断要向终端发送的广播消息无法 在一个分配时隙内发送完时， 基站将广播寻呼消息中的第二指示字段置为第 二预定值， 并将该广播寻呼消息发送给终端。 步骤 S 106 包括： 当终端在广播时隙接收到广播寻呼消息时， 终端判断 该广播寻呼消息中携带的第一指示字段的值为第一预定值， 则在监听广播时 隙之后继续监听该广播时隙的下一个时隙， 并继续在该广播时隙的下一个时 隙接收基站发送的广播消息； 当终端在分配时隙接收到广播寻呼消息时， 终 端判断该广播寻呼消息中携带的第二指示字段的值为第二预定值， 则在监听 分配时隙之后继续监听该分配时隙的下一个时隙， 并继续在该分配时隙的下 一个时隙接收基站发送的广播消息。 上述优选实施例提供了集群系统的广播消息发送方法的另一种具体实施 方案。 图 2是 居本发明实施例的集群系统的示意图， 该集群系统包括： 基站 10 ,用于当判断要向终端发送的广播消息无法在一个时隙内发送完 时， 在连续多个时隙内发送广播消息， 并在多个时隙中的每个时隙中发送用 于指示终端是否继续监听下一个时隙的信息； 终端 20 , 用于 居接收到的信息判断是否继续监听下一个时隙； 还用于 当判断结果为继续监听时， 继续监听下一个时隙直至接收完所要接收的所有 广播消息。 优选地， 上述用于指示终端是否继续监听下一个时隙的信息为广播寻呼 消息中的第一指示字段， 当第一指示字段的值为预定值时用于指示在广播时 隙收到广播寻呼消息的终端继续监听下一个时隙。 基站 10包括： 设置模块 101 , 用于当判断要向终端 20发送的广播消息 无法在一个广播时隙内发送完时， 将广播寻呼消息中的第一指示字段置为预 定值； 发送模块 102 , 用于将该广播寻呼消息发送给终端 20;

Figure imgf000009_0001
其中， READ_NEXT_SLOT_BCAST： 指示在广播时隙收到广播寻呼消 息的终端是否继续监听广播时隙的下一个时隙， 如果需要终端继续监听广播 时隙的下一个时隙， 则将 READ_NEXT_SLOT_BCAST置为 1 , 如果不需要 终端继续监听广播时隙的下一个时隙， 则将 READ_NEX _SLOT_BC AST置 为 0。 具体的处理流程包括基站和终端两侧的处理: ( 1 )基站侧处理: 基站如果给集群终端发送的广播消息无法在一个广播时隙发送完毕， 则 将广播寻呼消息中的 READ_NEXT_SLOT_BCAST字段置为 1 ; 基站如果给 集群终端发送的广播消息在一个广播时隙可以发送完毕， 将广播寻呼消息中 的 READ NEXT SLOT BCAST字段置为 0。
( 2 ) 终端侧处理： 终端在广播时隙收到广播寻呼消息后， 判断广播寻呼消息中携带的 READ NEXT SLOT BCAST字段， 如果 READ NEXT SLOT BCAST字段 值为 1 , 则终端监听寻呼信道广播时隙后还需要继续监听广播时隙的下一个 时隙， 继续在广播时隙的下一个时隙接收基站发送的消息。 终端在广播时隙收到广播寻呼消息后， 判断广播寻呼消息中携带的
READ NEXT SLOT BCAST字段， 如果 READ NEXT SLOT BCAST字段 值为 0, 则终端监听寻呼信道广播时隙后进入休眠状态， 等到下一个广播时 隙或分配时隙再继续监听。 优选实施例二： 基站不但可以指示终端在广播时隙继续监听下一个时隙， 对于终端分配 的时隙， 也可以指示终端继续监听分配时隙的下一个时隙。 随着协议的不断 扩展， 消息内容的不断增加， 当寻呼消息无法在终端分配的一个时隙内发送 完毕时， 也可以指示终端继续监听分配时隙的下一个时隙。 在集群呼叫广播 寻呼消息中扩展字段， 具体如表 2所示： 表 2
Figure imgf000010_0001
其中， READ_NEX _SLOT: 指示在分配时隙收到广播寻呼消息的终端 是否继续监听分配时隙的下一个时隙， 如果需要终端继续监听分配时隙的下 一个时隙， 则将 READ_NEXT_SLOT置为 1 , 如果不需要终端继续监听分配 时隙的下一个时隙， 则将 RE AD_NEXT_SLOT置为 0；
READ NEXT SLOT BCAST: 指示在广播时隙收到广播寻呼消息的终 端是否继续监听广播时隙的下一个时隙， 如果需要终端继续监听广播时隙的 下一个时隙， 则将 READ_NEXT_SLOT_BCAST置为 1 , 如果不需要终端继 续监听广播时隙的下一个时隙， 则将 READ_NEXT_SLOT_BCAST置为 0。 具体的处理流程包括基站和终端两侧的处理： ( 1 )基站侧处理： 基站如果给终端发送的广播消息无法在一个分配时隙发送完毕， 将广播 寻呼消息中的 READ_NEXT_SLOT字段置为 1; 基站如果给集群终端发送的 广播消息可以在一个分配时隙发送完毕， 则将广播寻呼消息中的 READ NEXT SLOT字段置为 0。 基站如果给集群终端发送的广播消息无法在一个广播时隙发送完毕， 则 将广播寻呼消息中的 READ_NEXT_SLOT_BCAST字段置为 1 ; 基站如果给 集群终端发送的广播消息在一个广播时隙可以发送完毕， 则将广播寻呼消息 中的 READ NEXT SLOT BCAST字段置为 0。
( 2 ) 终端侧处理： 终端在分配时隙收到广播寻呼消息后， 判断广播寻呼消息中携带的
READ_NEXT_SLOT字段， 如果 READ_NEXT_SLOT字段值为 1 , 则终端监 听寻呼信道分配时隙后还需要继续监听分配时隙的下一个时隙， 继续在分配 时隙的下一个时隙接收基站发送的消息。 终端在分配时隙收到广播寻呼消息后， 判断广播寻呼消息中携带的 READ NEXT SLOT字段， 如果 READ_NEXT_SLOT字段值为 0, 则终端监 听寻呼信道分配时隙后进入休眠状态， 等到下一个分配的时隙或广播时隙再 继续监听。 终端在广播时隙收到广播寻呼消息后， 判断广播寻呼消息中携带的 READ NEXT SLOT BCAST字段， 如果 READ NEXT SLOT BCAST字段 值为 1 , 则终端监听寻呼信道广播时隙后还需要继续监听广播时隙的下一个 时隙， 继续在广播时隙的下一个时隙接收基站发送的消息。 终端在广播时隙收到广播寻呼消息后， 判断广播寻呼消息中携带的
READ NEXT SLOT BCAST字段， 如果 READ NEXT SLOT BCAST字段 值为 0, 则终端监听寻呼信道广播时隙后进入休眠状态， 等到下一个广播时 隙或分配的时隙再继续监听。 另外需要说明的是， 对于需要在下一时隙继续发送的消息， 应保证消息 发送优先级与消息在当前时隙的发送优先级相同。 从以上的描述中， 可以看出， 本发明实现了如下技术效果： ( 1 ) 可以在集群网络规模不断扩大， 群组不断增加， 寻呼信道广播消 息发送数量不断上涨， 寻呼信道广播时隙无法满足多个群组广播消息发送需 求的情况下， 解决了集群系统寻呼信道广播消息发送的问题；
