示例性的, 下面分别对各种策略进行说明。
1、基于第一小区处于 FACH状态的用户数将所述用户设备重定 向至第二小区, 包括:
若确定所述第一小区处于 FACH状态的用户数大于或等于第一 重定向出门限, 并且,
所述第二小区处于 FACH状态的用户数小于或等于第一重定向 入门限, 或者, 若确定所述第二小区处于 FACH 状态的用户数与所 述第一小区处于 FACH 状态的用户数差值大于第一重定向相对门 限, 则确定将所述用户设备重定向至所述第二小区。
其中, 第一重定向出门限表示第一小区中, 可以将用户设备重 定向至其他小区的处于 FACH状态的用户数的临界值, 大于或等于 该第一重定向出门限, 说明第一小区 FACH信道负荷较大, 可以通 过重定向由其他小区进行负荷分担, 以提高 FACH信道的利用率, 进而提高系统容量。 第一重定向出门限可以由系统进行预先设置, 例如, 系统可以根据第一小区忙时 FACH信道的负荷情况进行设置, 若第一小区忙时 FACH信道的负荷较大, 则可以将第一重定向出门 限设置较小的值, 以使得更多的用户设备重定向至其他小区进行负 荷分担; 若第一小区忙时 FACH信道的负荷较小, 则可以将第一重 定向出门限设置较大的值, 需要说明的, 第一小区忙时 FACH信道 的负荷情况可由系统预定义或者预先获取,并不代表第一小区 FACH 信道的实时负荷情况。
其中, 第二小区是所述第一小区的盲切换邻区或者同覆盖的异 频邻区。
优选的, 根据小区的邻区关系, 如果存在多个第一小区的盲切 换邻区或者同覆盖的异频邻区, 则可以选择 FACH 用户数最少的小 区作为所述第二小区; 例如, 可以将多个第一小区的盲切换邻区或 者同覆盖的异频邻区以 FACH用户数进行排序, 选择 FACH用户数 最少的小区作为第二小区。
根据小区的邻区关系, 如果存在一个第一小区的盲切换邻区或 者同覆盖的异频邻区, 则可以将该第一小区的盲切换邻区或者同覆 盖的异频邻区作为第二小区。
其中, 第一重定入门限表示第二小区可以接受其他小区的用户 设备的重定向, 第二小区中处于 FACH状态的用户数的临界值, 小 于或等于该第一重定入门限, 说明第二小区 FACH信道负荷较小, 可以对其他小区进行负荷分担, 以提高 FACH信道的利用率, 进而 提高系统容量。 第一重定向入门限可以由系统进行设置, 例如, 系 统可以根据第二小区忙时 FACH信道的负荷情况进行设置, 若第二 小区忙时 FACH信道的负荷较小, 则可以将第一重定向重定入门限 设置较大的值, 以接受更多的用户设备重定向至本小区进行负荷分 担; 若第二小区忙时 FACH信道的负荷较大, 则可以将第一重定向 入门限设置较小的值。 需要说明的, 第二小区忙时 FACH信道的负 荷情况可由系统预定义或者预先获取, 并不代表第二小区 FACH信 道的实时负荷情况。
其中, 第一重定向相对门限表示能够将第一小区的用户设备重 定向至第二小区, 第二小区的 FACH 用户数与源第一小区的 FACH 用户数的差值的临界值, 例如, 若第一重定向相对门限为 5 时, 第 一小区 FACH用户数为 30 , 则第二小区 FACH用户数为 0〜25 时, 可以将第一小区的用户设备重定向至第二小区, 第二小区 FACH 用 户数大于 25时, 不能将第一小区的用户设备重定向至第二小区。 第 一重定向相对门限的取值可以由系统根据第二小区忙时 FACH信道 负荷情况进行预先设置, 例如, 若第二小区忙时 FACH信道负荷较 大, 可以将第一重定向相对门限设为较大的值, 以增加将第一小区 的用户设备重定向至第二小区的难度, 需要说明的, 第二小区忙时 FACH 信道负荷情况可由系统预定义或者预先获取, 并不代表第二 小区 FACH信道实时的负荷情况。
其中, RNC可以通过 P2F重定向将用户设备重定向至第二小区 或第二频点, 并且使处于 CELL— PCH态或 URA— PCH态的用户设备 重定向后目标状态为 CELL— FACH态。
2、基于所述第一小区处于 FACH状态的用户数确定将所述用户 设备重定向至所述第二频点, 可以包括:
若确定所述第一小区处于 FACH状态的用户数大于或等于第一 重定向出门限, 确定将所述用户设备重定向至所述第二频点。 例如, 可以通过 P2F重定向将用户设备重定向至第二小区或第二频点。
3、基于所述用户设备请求的业务的业务类型将所述用户设备重 定向至第二小区或者第二频点, 可以包括:

当所述第一小区为倾向驻留小区时, 若确定所述业务的业务类 型为非实时业务, 则确定将所述用户设备重定向至所述第二小区或 者第二频点;
或者, 当所述第一小区为非倾向驻留小区时, 若确定所述业务 的业务类型为实时业务, 则确定将所述用户设备重定向至所述第二 小区或者第二频点。例如, 当用户设备为 CELL PCH态或 URA PCH 时,可以通过 P2F重定向将用户设备重定向至第二小区或第二频点; 当所述用户设备的状态为 CELL— FACH态, 可以通过 F2P重定向将 用 户 设备重定向 至第 二小 区或第 二频点 , F2P 重定向是指 CELL— FACH态到 CELL PCH态或 URA— PCH态的重定向, F2P重定 向可以减少小区更新流程, 降低 RNC控制面信令负载, 减少 FACH 带宽占用。
其中, RNC可以通过小区更新请求携带的消息信元判断用户设 备发起的业务是非实时业务还是实时业务。
小区更新请求携带的消息信元可以包含小区更新原因 ( Cell update cause )和业务建立原因 ( Establishment cause )。 其中小区更 新原因 ( Cell update cause ) 可能的值有: 上行链路数据传输, 寻呼 响应, 小区重选等; 业务建立原因可能的取值有: 主叫交互业务, 主叫背景业务, 主叫高优先级信令, 被叫交互业务, 被叫背景业务, 被叫高优先级信令, 定制业务, 主叫会话业务, 被叫会话业务等。 示例性的, 非实时业务可以具体参考表 1 , 实时业务可以参考表 2。

其中,表 1 中终端协议版本指小区更新请求使用的协议的版本, " R5-v590 " 指 版本 5 ( Release 5 ) 的 V5.9.0 , 业务建立原因 ( establishment cause ) 即是在这个版本引入的。
例如,根据表 1 ,若确定小区更新请求携带的小区更新原因( Cell update cause ) 为寻呼响应, 业务建立原因 ( Establishment cause ) 为 主叫高优先级信令, 则可以确定用户设备请求的业务为非实时业务。
表 2
Figure imgf000017_0001
例如,根据表 2 ,若确定小区更新请求携带的小区更新原因( Cell update cause" ) 为寻呼响应, 业务建立原因 ( Establishment cause ) 为主叫会话业务, 则可以确定用户设备请求的业务为实时业务。
其中, 第二小区是所述第一小区的盲切换邻区或者同覆盖的异 频邻区。
优选的, 根据小区的邻区关系, 如果存在多个第一小区的盲切 换邻区或者同覆盖的异频邻区符合, 则可以选择高速下行分组接入 ( High Speed Downlink Packet Access , 简称 HSDPA ) 用户数最少的 小区作为所述第二小区; 例如, 可以将多个第一小区的盲切换邻区 或者同覆盖的异频邻区以 HSDPA用户数进行排序, 选择 HSDPA用 户数最少的小区作为第二小区。
根据小区的邻区关系, 如果存在一个第一小区的盲切换邻区或 者同覆盖的异频邻区, 则可以将该第一小区的盲切换邻区或者同覆 盖的异频邻区作为第二小区。

其中, 第二重定向出门限表示第一小区可以将用户设备重定向 至其他小区的下行功率负载的临界值, 大于或等于该第二重定向出 门限, 说明第一小区下行负荷较大, 可以通过重定向由其他小区进 行负荷分担, 以提高系统的容量。 第二重定向出门限可以由系统进 行预先设置, 例如, 系统可以根据第一小区忙时下行功率负载情况 进行设置, 若第一小区忙时下行功率负载较大, 则可以将第二重定 向出门限设置较小的值, 以使得第一小区中更多的用户设备重定向 至其他小区进行负荷分担; 若第一小区的下行功率负载较小, 则可 以将第二重定向出门限设置较大的值。 需要说明的, 第一小区忙时 下行功率负载情况可由系统预定义或者预先获取, 并不代表第一小 区的下行功率负载的实时情况。
其中, 第二小区是所述第一小区的盲切换邻区或者同覆盖的异 频邻区。
优选的, 根据小区的邻区关系, 如果存在多个第一小区的盲切 换邻区或者同覆盖的异频邻区,则可以选择 HSDPA用户数最少的小 区作为所述第二小区; 例如, 可以将多个第一小区的盲切换邻区或 者同覆盖的异频邻区以 HSDPA用户数进行排序, 选择 HSDPA用户 数最少的小区作为第二小区。

其中, 第二重定入门限表示第二小区可以接受其他小区的用户 设备的重定向, 第二小区的下行功率负载的临界值, 小于或等于该 第二重定入出门限, 说明第二小区下行功率负载负荷较小, 可以对 其他小区进行负荷分担, 以提高多载波小区容量。 第二重定向入门 限可以由系统进行预先设置, 例如, 系统可以根据第二小区忙时下 行功率负载情况进行设置, 若第二小区忙时下行功率负载负荷较大, 则可以将第二重定向出门限设置较小的值, 若第二小区忙时下行功 率负载负荷较小, 则可以将第二重定向出门限设置较小的值, 以接 受更多的用户设备重定向至第二小区进行负荷分担。 需要说明的, 第二小区忙时下行功率负载情况由系统预定义或者预先获取, 并不 代表第二小区的下行功率负载的实时情况。
其中, 第二重定向相对门限表示能够将第一小区的用户设备重 定向至第二小区, 第二小区的下行功率负载与第一小区的下行功率 负载的差值的临界值, 例如, 若第二重定向相对门限为 5 时, 第一 小区下行功率负载为 30 , 则第二小区下行功率负载为 0〜25 时, 可 以将第一小区的用户设备重定向至第二小区, 第二小区的下行功率 负载大于 25时, 不能将第一小区的用户设备重定向至第二小区。 第 二重定向相对门限的取值可以由系统根据第二小区忙时下行功率负 载负荷情况进行预先设置, 例如, 若第二小区忙时下行功率负载负 荷较大, 可以将第二重定向相对门限设为较大的值, 以增加将第一 小区的用户设备重定向至第二小区的难度。 需要说明的, 第二小区 忙时下行功率负载负荷情况由系统预定义或者预先获取, 并不代表 第二小区下行功率负载负荷的实时情况。

其中, 本实施例可以应用于各种组网情况下的业务分层的重定 向的实现, 仅是示例性的, 在此仍以图 1 所示的宏微组网情况下进 行说明。 RNC 可配置有多个小区, 其中, 如图 1 所示, 包含 F 1 宏 小区, F2宏小区, 以及 F2 .小区。 本实施例中, 支设 F 1宏小区为 第一小区, 即 UE初始状态在 F 1宏小区接入, 假设 URA— PCH态或 CELL PCH态的 UE在 F 1宏小区发送小区更新请求, F 1宏小区可以 为倾向驻留小区。
302 : RNC判断用户设备请求的业务是否为 NRT业务, 若是, 则执行步骤 304 , 若否, 则执行步骤 303。

305 : 判断是小区场景还是频点场景, 若是小区场景, 则执行步 骤 306 , 若是频点场景, 则执行步骤 3 12 ;
其中, 判断是小区场景还是频点场景的方法可如上述实施例所 述, 在此不再赘述„
306、判断是否存在第一小区的盲切换邻区或者同覆盖的异频邻 区, 若是, 则执行步骤 307 , 若否, 则执行步骤 303 ;

下面分别对处理器 902的各种功能进行说明。
1、 处理器 902用于, 若确定所述第一小区处于 FACH状态的用 户数大于或等于第一重定向出门限, 并且,
所述第二小区处于 FACH状态的用户数小于或等于第一重定向 入门限, 或者, 若确定所述第二小区处于 FACH 状态的用户数与所 述第一小区处于 FACH 状态的用户数差值大于第一重定向相对门 限, 则确定将所述用户设备重定向至所述第二小区。
其中, 第一重定向出门限表示第一小区中, 可以将用户设备重 定向至其他小区的处于 FACH状态的用户数的临界值, 大于或等于 该第一重定向出门限, 说明第一小区 FACH信道负荷较大, 可以通 过重定向由其他小区进行负荷分担, 以提高 FACH信道的利用率, 进而提高系统容量。 第一重定向出门限可以由系统进行预先设置, 例如, 系统可以根据第一小区忙时 FACH信道的负荷情况进行设置, 若第一小区忙时 FACH信道的负荷较大, 则可以将第一重定向出门 限设置较小的值, 以使得更多的用户设备重定向至其他小区进行负 荷分担; 若第一小区忙时 FACH信道的负荷较小, 则可以将第一重 定向出门限设置较大的值, 需要说明的, 第一小区忙时 FACH信道 的负荷情况可由系统预定义或者预先获取,并不代表第一小区 FACH 信道的实时负荷情况。
其中, 第二小区是所述第一小区的盲切换邻区或者同覆盖的异 频邻区。
优选的, 根据小区的邻区关系, 如果存在多个第一小区的盲切 换邻区或者同覆盖的异频邻区, 则可以选择 FACH 用户数最少的小 区作为所述第二小区; 例如, 可以将多个第一小区的盲切换邻区或 者同覆盖的异频邻区以 FACH用户数进行排序, 选择 FACH用户数 最少的小区作为第二小区。
根据小区的邻区关系, 如果存在一个第一小区的盲切换邻区或 者同覆盖的异频邻区, 则可以将该第一小区的盲切换邻区或者同覆 盖的异频邻区作为第二小区。
其中, 第一重定入门限表示第二小区可以接受其他小区的用户 设备的重定向, 第二小区中处于 FACH状态的用户数的临界值, 小 于或等于该第一重定入门限, 说明第二小区 FACH信道负荷较小, 可以对其他小区进行负荷分担, 以提高 FACH信道的利用率, 进而 提高系统容量。 第一重定向入门限可以由系统进行设置, 例如, 系 统可以根据第二小区忙时 FACH信道的负荷情况进行设置, 若第二 小区忙时 FACH信道的负荷较小, 则可以将第一重定向重定入门限 设置较大的值, 以接受更多的用户设备重定向至本小区进行负荷分 担; 若第二小区忙时 FACH信道的负荷较大, 则可以将第一重定向 入门限设置较小的值。 需要说明的, 第二小区忙时 FACH信道的负 荷情况可由系统预定义或者预先获取, 并不代表第二小区 FACH信 道的实时负荷情况。
其中, 第一重定向相对门限表示能够将第一小区的用户设备重 定向至第二小区, 第二小区的 FACH 用户数与源第一小区的 FACH 用户数的差值的临界值, 例如, 若第一重定向相对门限为 5 时, 第 一小区 FACH用户数为 30 , 则第二小区 FACH用户数为 0〜25 时, 可以将第一小区的用户设备重定向至第二小区, 第二小区 FACH 用 户数大于 25时, 不能将第一小区的用户设备重定向至第二小区。 第 一重定向相对门限的取值可以由系统根据第二小区忙时 FACH信道 负荷情况进行预先设置, 例如, 若第二小区忙时 FACH信道负荷较 大, 可以将第一重定向相对门限设为较大的值, 以增加将第一小区 的用户设备重定向至第二小区的难度, 需要说明的, 第二小区忙时
FACH 信道负荷情况可由系统预定义或者预先获取, 并不代表第二 小区 FACH信道实时的负荷情况。
其中, RNC可以通过 P2F重定向将用户设备重定向至第二小区 或第二频点, 并且使处于 CELL— PCH态或 URA— PCH态的用户设备 重定向后目标状态为 CELL— FACH态。
2、 处理器 902用于, 若确定所述第一小区处于 FACH状态的用 户数大于或等于第一重定向出门限, 确定将所述用户设备重定向至 所述第二频点。 例如, 可以通过 P2F重定向将用户设备重定向至第 二小区或第二频点。
3、 处理器 902用于, 根据所述小区更新请求消息判断所述用户 设备请求的业务的业务类型, 其中, 所述业务类型包含 RT 业务或 NRT业务;
当所述第一小区为倾向驻留小区时, 若确定所述业务的业务类 型为非实时业务, 则确定将所述用户设备重定向至所述第二小区或 者第二频点;
或者, 当所述第一小区为非倾向驻留小区时, 若确定所述业务 的业务类型为实时业务, 则确定将所述用户设备重定向至所述第二 小区或者第二频点。例如, 当用户设备为 CELL— PCH态或 URA— PCH 时,可以通过 P2F重定向将用户设备重定向至第二小区或第二频点; 当所述用户设备的状态为 CELL— FACH态, 可以通过 F2P重定向将 用 户 设备重定向 至第 二小 区或第 二频点 , F2P 重定向是指 CELL— FACH态到 CELL— PCH态或 URA— PCH的重定向, F2P重定向 可以减少小区更新流程, 降低 RNC控制面信令负载, 减少 FACH带 宽占用。
其中, RNC可以通过小区更新请求携带的消息信元判断用户设 备发起的业务是非实时业务还是实时业务。
小区更新请求携带的消息信元可以包含小区更新原因 ( Cell update cause )和业务建立原因 ( Establishment cause )。 其中小区更 新原因 ( Cell update cause ) 可能的值有: 上行链路数据传输, 寻呼 响应, 小区重选等; 业务建立原因可能的取值有: 主叫交互业务, 主叫背景业务, 主叫高优先级信令, 被叫交互业务, 被叫背景业务, 被叫高优先级信令, 定制业务, 主叫会话业务, 被叫会话业务等。 示例性的, 非实时业务可以具体参考表 1 , 实时业务可以参考表 2。 在此不再赘述。
其中, 第二小区是所述第一小区的盲切换邻区或者同覆盖的异 频邻区。
优选的, 根据小区的邻区关系, 如果存在多个第一小区的盲切 换邻区或者同覆盖的异频邻区,则可以选择高速下行分组接入( High Speed Downlink Packet Access , 简称 HSDPA ) 用户数最少的小区作 为所述第二小区; 例如, 可以将多个第一小区的盲切换邻区或者同 覆盖的异频邻区以 HSDPA用户数进行排序, 选择 HSDPA用户数最 少的小区作为第二小区。
根据小区的邻区关系, 如果存在一个第一小区的盲切换邻区或 者同覆盖的异频邻区, 则可以将该第一小区的盲切换邻区或者同覆 盖的异频邻区作为第二小区。
3、 处理器 902用于, 若确定所述第一小区的下行功率负载大于 或等于第二重定向出门限, 并且,
所述第二小区的下行功率负载小于或等于第二重定向入门限, 或者, 若确定所述第二小区的下行功率负载与所述第一小区下行功 率负载的差值大于第二重定向相对门限, 则确定将所述用户设备重 定向至所述第二小区。
其中, 第二重定向出门限表示第一小区可以将用户设备重定向 至其他小区的下行功率负载的临界值, 大于或等于该第二重定向出 门限, 说明第一小区下行负荷较大, 可以通过重定向由其他小区进 行负荷分担, 以提高系统的容量。 第二重定向出门限可以由系统进 行预先设置, 例如, 系统可以根据第一小区忙时下行功率负载情况 进行设置, 若第一小区忙时下行功率负载较大, 则可以将第二重定 向出门限设置较小的值, 以使得第一小区中更多的用户设备重定向 至其他小区进行负荷分担; 若第一小区的下行功率负载较小, 则可 以将第二重定向出门限设置较大的值。 需要说明的, 第一小区忙时 下行功率负载情况可由系统预定义或者预先获取, 并不代表第一小 区的下行功率负载的实时情况。
其中, 第二小区是所述第一小区的盲切换邻区或者同覆盖的异 频邻区。
优选的, 根据小区的邻区关系, 如果存在多个第一小区的盲切 换邻区或者同覆盖的异频邻区,则可以选择 HSDPA用户数最少的小 区作为所述第二小区; 例如, 可以将多个第一小区的盲切换邻区或 者同覆盖的异频邻区以 HSDPA用户数进行排序, 选择 HSDPA用户 数最少的小区作为第二小区。
根据小区的邻区关系, 如果存在一个第一小区的盲切换邻区或 者同覆盖的异频邻区, 则可以将该第一小区的盲切换邻区或者同覆 盖的异频邻区作为第二小区。
其中, 第二重定入门限表示第二小区可以接受其他小区的用户 设备的重定向, 第二小区的下行功率负载的临界值, 小于或等于该 第二重定入出门限, 说明第二小区下行功率负载负荷较小, 可以对 其他小区进行负荷分担, 以提高多载波小区容量。 第二重定向入门 限可以由系统进行预先设置, 例如, 系统可以根据第二小区忙时下 行功率负载情况进行设置, 若第二小区忙时下行功率负载负荷较大, 则可以将第二重定向出门限设置较小的值, 若第二小区忙时下行功 率负载负荷较小, 则可以将第二重定向出门限设置较小的值, 以接 受更多的用户设备重定向至第二小区进行负荷分担。 需要说明的, 第二小区忙时下行功率负载情况由系统预定义或者预先获取, 并不 代表第二小区的下行功率负载的实时情况。
