- CDMA code division multiple access
- Background Art Currently, there are two paging modes in a CDMA system: a slotted mode and a non-slotted mode.
- the non-slot mode refers to: the mobile station continuously monitors the Forward-Paging Channel (F-PCH), instead of listening to the specified time slot.
- F-PCH Forward-Paging Channel
- the mobile station When operating in the slot mode, the mobile station does not continuously monitor the F-PCH in the idle state, but receives the F-PCH in a specified period of time at regular intervals according to certain rules, in each of the two intercepts.
- the mobile station is equivalent to being in a dormant state, that is, the baseband processor and the radio frequency circuit are reduced in operation or even stopped, so that power consumption can be reduced.
- the basic unit of the split time is the slot of the F-PCH (slot), and the duration of one slot is 80 ms, that is, four 20 ms paging channel frames.
- a mobile station in slotted mode usually listens to the F-PCH at regular intervals in an idle state.
- This time interval is called a Slot Cycle, and usually monitors one or two in one slot period.
- the user can adjust the length of the desired slot period by setting the slot period index of the mobile station by itself, and the adjustment will pass the parameter.
- the number change registration, call, page response and other messages are reported to the system.
- the user's adjustment range for the slot cycle is limited by the current network configuration.
- the mobile station in the slot mode, the mobile station only listens for paging at a certain time, and generally only listens to one or two time periods in the paging channel slot period, thereby saving power consumption of the mobile station. Extends battery life.
- the mobile station needs to listen to all paging time periods.
- the Push To Talk (PTT) Slot Cycle Index (PTT Max Slot Cycle Index) is introduced, which specifies the current Parameters such as the maximum slot cycle index allowed in the PTT system.

Description
CDMA集群业务基站确定寻呼时隙的方法 技术领域 本发明涉及通信领域, 并且特别地, 涉及码分多址 ( Code Division Multiple Access, 简称为 CDMA ) 集群业务基站寻呼时隙的确定方法。 背景技术 目前, CDMA***中存在两种寻呼模式: 时隙模式 ( Slotted Mode ) 和 非时隙模式 ( Non- Slotted Mode )。 其中, 非时隙模式是指: 移动台对前向寻 呼信道 ( Forward-Paging Channel, 简称为 F-PCH )进行连续监听, 而不是按 照指定的时隙进行监听的工作模式。 由于移动台需要对 F-PCH连续地进行解调和解码, 并处理 F-PCH中的 消息, 这样会导致电池中的电量消耗得很快; 而且, 在 F-PCH上没有寻呼的 情况下, ***会循环广播***参数消息, 对于已经正确获得了这些参数而且 处于空闲状态的移动台来说, 重复接收这些参数也是一种浪费。 因 iH , 为了减少移动台对 F-PCH不必要的监听、 并且延长电池在空闲 状态下的使用时间, 在 IS-95 中规定了时隙模式, 该模式可与非时隙模式对 应。 在工作于时隙模式时, 移动台在空闲状态下并不连续地监听 F-PCH, 而 是根据一定的规则, 每隔一定时间在指定的时间段内接收 F-PCH, 在每两次 监听 F-PCH的间隔之中, 移动台相当于处于休眠状态, 即基带处理器和射频 电路减少工作、 甚至停止工作, 这样就能够降低耗电量。 在时隙模式中, 划分时间的基本单位为 F-PCH的时隙 ( slot ) , —个时 隙的持续时间为 80ms, 也就是 4个 20ms的寻呼信道帧。 处于时隙模式的移 动台通常在空闲状态下每隔一定的时间才去监听一次 F-PCH, 这个时间间隔 叫故时隙周期(Slot Cycle ), 并且在一个时隙周期内通常监听一或两个时隙。 时隙周期的长度以 1.28s ( =16 X 80ms ) 计, 它必须是 1.28s的 1、 2、 4、 8、 16、 32、 64、 或 128倍, 若以 T表示时隙周期长度, 则 T=1.28 x 2's, 其中, i为时隙周期指数 ( Slot Cycle Index ), 其取值可以为 0到 7的整数, 而时隙 周期的最大值可为 2048 个时隙, 即, 163.84s。 并且, 用户可以通过自行设 置移动台的时隙周期指数来调整其希望的时隙周期的长短, 调整后将通过参

数变更登记、 起呼、 寻呼响应等消息报告给***。 此外, 用户对时隙周期的调整范围受到当前网络配置情况的限制。 在广 播服务区内的移动台的***参数消息中有一个参数, 即, 最大时隙周期指数 ( Max Slot Cycle Index ), 该指数规定了当前***允许使用的最大的时隙周 期, 移动台实际使用的时隙周期指数还需要才艮据实际情况确定。 如上所述, 在时隙模式下, 移动台只在某个特定的时间监听寻呼, 一般 只监听寻呼信道时隙周期中的一个或两个时间段, 节省了移动台的耗电量, 延长了电池寿命。 另一方面, 在非时隙工作模式下, 移动台则需要监听所有 的寻呼时间段。 在集群***下, 除了原***的时隙周期指数等参数外, 还引入了最大即 按即说 ( Push To Talk, 简称为 PTT ) 时隙周期指数 ( PTT Max Slot Cycle Index ), 它规定了当前 PTT***中允许使用的最大的时隙周期指数等参数。 此外, 在 PTT ***中, 存在多种原因导致移动台开机后被叫接入曼的 问题, 使得 PTT呼叫等功能受到了限制。 然而, 目前尚未提出能够解决该问 题的技术方案。 发明内容 考虑到相关技术中存在的移动台开机后被叫接入慢的问题而做出本发 明,本发明的主要目的在于提供一种改进的 CDMA集群业务基站寻呼时隙的确 定方案, 以解决相关技术中的上述问题至少之一。 为了达到上述目的, 根据本发明的一个方面, 提供了一种 CDMA集群 业务基站寻呼时隙的确定方法。 根据本发明的 CDMA集群业务基站寻呼时隙的确定方法包括: 如果基 站判断移动台的 PTT版本号大于或等于预定的值,且基站得到移动台的负时 隙信息,将最大 PTT时隙周期指数、 PTT时隙周期指数、最大时隙周期指数、 以及时隙周期指数中的最小值作为第一时隙周期指数, 基站以基于第一时隙 周期指数的时隙周期对移动台进行寻呼; 如果基站判断移动台的 PTT版本号大于或等于预定的值, 且如果基站 没有得到移动台的负时隙信息, 则基站以最大 PTT时隙周期指数、 最大时隙

周期指数、 以及时隙周期指数中的最小值作为第二时隙周期指数, 基站以基 于第二时隙周期指数的时隙周期对移动台进行寻呼; 如果基站判断移动台的 PTT协议版本号小于预定的值, 则基站以最大 时隙周期指数以及时隙周期指数中的最小值作为第三时隙周期指数, 基站以 基于第三时隙周期指数的时隙周期对移动台进行寻呼; 当基站不能确定移动台是否以时隙方式工作或者不能确定移动台的时 隙周期指数时, 时隙周期指数的取值为 1 , 然后再按照上述三种方式进行计 算。 其中, 移动台的 PTT版本号与移动台的功能相对应。 并且, 如果移动台的 PTT版本号为 1 , 则其对应于 PTT增强式组呼; 如果移动台的 PTT版本号为 2 , 则其对应于支持移动台快速接入呼叫; 如果 移动台的 PTT版本号为 3 , 则其对应于支持移动台大组寻呼; 如果移动台的 PTT版本号为 5。 则其对应于支持移动台负时隙寻呼以及 PPT传统式组呼第 一阶段; 如果移动台的 PTT版本号为 6, 则其对应于支持移动台负时隙寻呼 以及 PPT传统式组呼第二阶段。 此外, 该预定的值为 1至 9中的任一值。 另外, 上述移动台可包括移动终端、 固定台、 以及车载台且并不限于这 些设备。 借助于本发明的上述技术方案, 通过使用负时隙, 基站确定寻呼时隙的 时隙周期指数, 最后根据该指数来确定寻呼时隙周期, 能够解决相关技术中 存在的移动台开机后被叫接入慢的问题, 从而能够提高开机接入的速度。 本发明的其它特征和优点将在随后的说明书中阐述, 并且, 部分地从说 明书中变得显而易见, 或者通过实施本发明而了解。 本发明的目的和其他优 点可通过在所写的说明书、 权利要求书、 以及附图中所特別指出的结构来实 现和获得。 附图说明 附图用来提供对本发明的进一步理解, 并且构成说明书的一部分, 与本 发明的实施例一起用于解释本发明, 并不构成对本发明的限制。 在附图中:

6 P23523
如图 4所示, 首先, 如果用户指示移动台爹改了时隙周期指数, 则移动 台将执行参数改变登记; 然后, 在移动台支持负时隙寻呼的情况下, 如果基站的***识別号和网 络识別号与***识別号和网络识別号列表中的任一项都不匹配, 则移动台以 不大于最大时隙周期指数和 1中较小值的值作为时隙周期指数, 否则: 情况一, 如果移动台在寻呼信道的开销消息上收到负时隙寻呼周期信 息, 且移动台保存有负时隙寻呼周期信息, 则移动台通过从最大 PTT时隙周 期指数、 PTT时隙周期指数, 最大时隙周期指数、 以及时隙周期指数这四个 参数中获取最小值来计算寻呼时隙; 情况二, 如果移动台在寻呼信道的开销消息上收到负时隙寻呼周期信 息, 但移动台没有保存有负时隙寻呼周期信息, 则移动台通过从最大 PTT时 隙周期指数、 最大时隙周期指数、 时隙周期指数这三个参数中获取最小值来 计算寻呼时隙; 情况三,如果移动台在寻呼信道的开销消息上没有收到负时隙寻呼周期 信息, 但移动台保存有负时隙寻呼周期信息, 则移动台通过从 PTT时隙周期 指数、 最大时隙周期指数、 以及时隙周期指数这三个参数中获取最小值来计 算寻呼时隙; 以及 情况四,如果移动台在寻呼信道的开销消息上没有收到负时隙寻呼周期 信息, 且移动台也没有保存负时隙寻呼周期信息, 移动台通过从最大时隙周 期指数、 时隙周期指数中获取最小值来计算寻呼时隙。 釆用本发明的方法后 ,对执行非集群业务时基站确定寻呼时隙的方法也 会带来一定影响, 详述如下。 图 3示出了釆用根据本发明实施例的 CDMA集群业务基站寻呼时隙的 确定方法后, 执行非集群业务时基站寻呼时隙的确定方法的流程。 如图 3所示, 执行非集群业务时基站确定寻呼时隙的方法包括: 若基站 确定移动台以时隙方式工作, 并且确定移动台首选的时隙周期指数时, 将移 动台首选的时隙周期指数和最大时隙周期指数中较小值作为第四时隙周期指 数, 并且基站以基于第四时隙周期指数的时隙周期对移动台进行寻呼; 以及 当基站不能确定移动台是否以时隙方式工作或者不能确定移动台的时隙周期
7 P23523
指数时, 将移动台首选的时隙周期指数和 1中较小的值作为第五时隙周期指 数, 并且基站以基于第五时隙周期指数的时隙周期对移动台进行寻呼。 下面结合具体实例描述才艮据本发明实施例的 CDMA集群业务基站寻呼 时隙以及与其相关联的移动台寻呼时隙的确定过程。 实例 1 在 PTT终端侧, A、 B 等多个终端为同一个群组, 并均隶属于基站 C 的情况下,确定终端 A和基站 C的时隙周期。 支设基站 C侧的 Max PTT Slot Cycle Index值为 4, 当前 PTT Slot Cycle Index值为― 1 , Slot Cycle Index值 为 4, Max Slot Cycle Index值为 6。 首先, 终端 A开机, 进行开机登记, 接收***参数消息, 收到后就可 以才艮据这些参数确定其本身的时隙了。 如果终端 A在寻呼信道的开销消息上 收到负时隙寻呼周期的信息(由 PTT***参数消息中的中得到 Max PTT Slot Cycle Index ), 且终端 A 自身保存有负时隙寻呼周期信息 (例如, PTT Slot Cycle Index ), 终端 A根据 Min ( Max PTT Slot Cycle Index, PTT Slot Cycle Index, Max Slot Cycle Index, Slot Cycle Index )来计算寻呼时隙, 即, 在(4, - 1 , 6, 4 ) 中取最小值, 从而取 _ 1为其的寻呼时隙周期。 之后, 确定基站 C的寻呼时隙, 假如终端 A发送给基站 C的 PTT版本 号等于 5以及终端 A的 Slot Cycle Index值为 - 1 ,基站 C才艮据公式 Min( Max PTT Slot Cycle Index, PTT Slot Cycle Index, Max Slot Cycle Index, Slot Cycle Index ) 确定的时隙周期指数对终端 A进行寻呼。 即, 从 (4, - 1 , 6, - 1 ) 中取最小值, 从而可确定时隙周期指数为 _ 1 , 以对终端 A进行寻呼。 实例 2 在 PTT终端侧, A、 B等终端为同一个群组, 且均隶属于基站 C的情况 下, 确定终端 A和基站 C的时隙周期。 i设基站 C侧的 Max PTT Slot Cycle Index值为 4, 当前 PTT Slot Cycle Index值为 1 , Slot Cycle Index值为 4, Max Slot Cycle Index值为 6。 首先, 终端 A开机, 进行开机登记, 接收***参数消息, 收到该消息 后, 终端 A就可以才艮据这些参数确定其本身的时隙。 如果终端 A在寻呼信道的开销消息上没有收到负时隙寻呼周期的信息,
8 P23523
但是终端 A自身保存有负时隙寻呼周期信息,所以终端 A根据公式 Min( PTT Slot Cycle Index, Max Slot Cycle Index, Slot Cycle Index ) 来计算寻呼时隙, 即, 在 ( 1 , 6, 4 ) 中选择最小值, 从而确定当前的寻呼时隙周期为 1。 之后, 在基站 C侧确定寻呼时隙, 假如终端 A发送给基站 C的 PTT版 本号等于 6、以及终端 A的 Slot Cycle Index值为 1 ,基站 C才艮据公式 Min( Max PTT Slot Cycle Index, PTT Slot Cycle Index, Max Slot Cycle Index, Slot Cycle Index ) 的时隙周期对终端 A 进行寻呼。 也即, 从(4, 1 , 6, 1 ) 里面取最 小值, 最后, 确定时隙周期指数为 1 , 从而基站 C根据该时隙周期指数对终 端 A进行寻呼。 另外, 可以通过硬件、 软件、 固件、 中间件、 微码、 硬件描述语言或其 组合来实现实施例。 当用软件、 固件、 中间件或 4啟码来实现时, 可以在诸如 存储介质的机器可读介质中存储用于执行必要任务的程序代码或码段。 (多 个) 处理器可以执行必要任务。 码段可以表示进程、 函数、 子程序、 程序、 例行程序、 子例行程序、 模块、 对象、 软件包、 类、 或指令、 数据结构、 或 程序语言的任意组合。 通过传输和 /或接收信息、 数据、 自变量、 或存储内容 来将码段耦合到另一码段或硬件电路。 信息、 自变量、 参数、 数据等可以经 由包括存储器共享、 消息传递、 令牌传递、 网络传输等的任意合适方式来传 递、 传输、 或传送。 综上所述, 借助于本发明的上述技术方案, 通过使用负时隙, 基站确定 寻呼时隙的时隙周期指数, 最后根据该指数来确定寻呼时隙, 能够解决相关 技术中存在的移动台开机后被叫接入慢的问题, 能够提高开机接入的速度, 并且能够为不支持负时隙寻呼的基站和终端确定寻呼时隙。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本 领域的技术人员来说, 本发明可以有各种更改和变^^ 凡在本发明的^^申和 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。
