现有中国移动的网络条件下 TD-SCDMA ( Time Division- Synchronous Code Division Multiple Access, 时分同步码分多址接入)网络和 GSM ( Global System of Mobile communication, 全球移动通信系统) 网络共存, 而移动网络 的终端主要有如下 3种模式:
1、 GSM单卡单模单待, 即通过 GSM单模终端插入一张 SIM ( Subscriber
Identity Module, 用户识别模块)卡, 仅驻留在 GSM网络中, 接受相关网络 服务; 其局限性在于, 用户只能使用简单的 GPRS ( General Packet Radio Service, 通用分组无线服务)数据业务, 不能享受高速数据业务。
2、 TD-SCDMA/GSM单卡双模单待, 即通过 TD-SCDMA/GSM双模终端 插入一张 USIM ( Universal Subscriber Identity Module, 通用用户识别模块) 卡, 选择信号较好网络驻留, 接受相关网络服务; 其局限性在于, UE ( User Equipment, 用户设备 /终端 )可能因为网络覆盖的差异不断评估测量结果进行 制式间的小区重选, 从而引起掉话及耗电的问题。 3、 TD-SCDMA/GSM双卡双模双待, 即通过在 TD-SCDMA/GSM双模终 端中分别插入一张 SIM卡和 USIM卡,每张卡分别对应一套独立的射频电路, 分别驻留在 3G和 2G网络下; 其局限性在于, 用户需要办理两张卡, 拥有两 个号码, 影响用户体验, 且使用起来非常不便。

下文中将结合附图对本发明的实施例进行详细说明。 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任意组合。
本实施方式提供一种双模双待终端快速小区重选方法, 釆用以下方案: 双模双待终端移动至第一制式的信号弱场,触发第一制式下的小区重选, 同时请求第二制式进行协助测量;
所述第二制式利用射频空闲时间 (GAP)进行测量评估,并将测量结果通知 所述第一制式。
其中, 所述第一制式和第二制式包括 TD制式 /GSM制式。
可选的, 所述第一制式在请求所述第二制式进行协助测量时, 将指定的 频段和 /或小区发送给所述第二制式;
所述第二制式对所述指定的频段和 /或 d、区进行测量评估。
可选的, 所述第一制式在请求所述第二制式进行协助测量时, 将 RSCP ( Received Signal Code Power, 接收信号码功率) 门限发送给所述第二制式; 所述第二制式根据所述门限进行测量评估, 并将满足所述门限的小区的 信息通知所述第一制式。
可选的, 所述第一制式接收到所述小区的信息时, 更新本地的小区重选 候选列表合集, 并按照信号强弱依次发起重选。
可选的, 所述第二制式在完成测量评估后, 重新回到完全射频模式。 此外, 所述终端在待机稳定状态下, 通过小区基站广播的系统信息配置 的部区参数, 记录当前驻留制式小区的异制式邻区信息;
所述第二制式根据记录的异制式邻区信息, 进行协助测量。
此外, 当所述第一制式完成小区重选驻留后, 更新记录的异制式邻区信 息。
本实施方式的双模双待终端快速小区重选方法, 具体包括以下步骤: 步骤 1 , 双模双待终端在两种制式 (分别记为 A制式和 B制式)下驻留在 一个合适小区, 进入待机稳态, 并通过小区基站广播的系统信息配置的邻区 参数, 记录当前驻留制式小区的异制式邻区信息;
步骤 2, 终端移动进入到 A制式为弱场的环境中, 终端评估弱场制式下 服务小区信号强度后, 触发在 A制式下的小区重选过程;
步骤 3 , A制式通知 B制式, 触发 B进入 Gap工作模式, A制式会将以 下信息通过接口信令发给 B制式: (l)RSCP门限阔值; (2)请求 B制式承担的 指定频段和 /或小区;
步骤 4, A制式下进行小区重选过程的同时, B制式利用射频空闲时间 (Gap)进行测量评估工作, 通过所承担的指定频段和 /或小区, 进行协助测量; 步骤 5 , A制式下进行小区重选过程的同时, 如果 B制式发现了满足此 门限的异制式小区, 那么则立即将此小区信息 ^艮给 A制式, 同时进行下一个 指定频点的测量信号评估, 如果所有邻区评估完毕, 则 B制式重新回到完全 射频工作模式;
步骤 6, A制式更新小区重选候选列表, 按照信号强弱依次发起重选动 作, 如果找到小区驻留, 则执行步骤 7; 如果仍未找到合适小区驻留, 则返 回步骤 4;
步骤 7, 完成 A制式的小区重选动作, 重新接受 A制式网络服务。
双模双待终端在两种制式下分别驻留在一个合适小区, 进入待机稳态; 当终端移动进入到某一个制式为弱场的环境中, 终端评估信号强度后将触发 在此弱场制式下的小区重选过程。
图 1和图 2分别为本发明双模双待终端 TD小区和 GSM小区重选策略的 示意图。 当射频 1在启动 TD制式小区重选流程时, 向射频 2发送协助重选 的请求, 触发另一个制式进入 Gap 工作模式, 该请求中可以携带信号强度 RSCP门限阔值; 射频 2根据请求中携带的信息, 利用射频空闲时间 (Gap)进 行测量评估工作, 通过小区基站广播的系统信息 (GSM: SI2quarter; TD: Sibl l/Sibl2)配置的邻区参数, 进行协助测量。 如果另一个制式发现了满足此 门限的异制式小区, 则立即上报弱场制式此小区信息, 弱场制式在得到此信 息后更新本地的小区重选候选列表合集, 按照信号强弱依次发起重选动作。 如果不满足门限条件则继续尝试测量下一个异制式频点, 直到尝试完毕, 重 新回到完全射频工作模式。 弱场制式如果成功选到一个新小区, 则需要再次 更新记录的异制式邻区信息, 流程结束, 否则, 继续从小区重选候选列表中 选取下一个小区进行尝试重选驻留。 此外, 鉴于以下因素: (1)弱制式射频可以完全时间用于测量评估, 而辅 助制式使用 Gap空闲时间工作, 在测量评估能力上必然会弱于前一制式; (2) 两块射频可能测量评估小区频段重复, 导致推荐的重选小区重复, 浪费测量 评估时间。 优选地, 可以对两块射频的具体测量评估进行分工细化。 例如, 全时间测量评估射频承担较多的频段或小区评估工作, Gap模式工作射频承 担剩余的较少频段或小区评估工作, 具体比例分配可根据实际厂家射频芯片 的性能, 进行现场调试后的经验值决定, 本发明在此不作具体量化。
此外, 本发明实施例上述小区重选方案也可以应用于衍生到双弱场的场 景中。
图 3为本发明的实施例的双模双待终端开机分别驻留在 TD-SCDMA (简 称 TD )和 GSM两种制式下, 终端移动到 TD弱场, 在 TD制式下发生了小 区重选的流程示意图。 如图 3所示, 该流程具体包括如下步骤:
步骤 301 : UE开机分别驻留 TD和 GSM制式, 进入待机状态, 等待发 起业务。
步骤 302: UE终端读取系统信息, 记录当前双制式服务小区对应的异制 式邻区配置信息。
步骤 303: UE移动至 TD信号弱场, 触发 TD制式的小区重选流程。 步骤 304: TD制式通过内部信令通知 GSM制式进入射频 Gap时间工作 模式, 并将代表 TD小区信号的最低满足驻留的 RSCP门限阔值带给 GSM。
步骤 305: 判断当前驻留 GSM制式小区是否存在未尝试的 TD邻区, 如 果存在, 转到步骤 307; 如果不存在则, 转到步骤 306。
步骤 306: GSM离开 Gap工作模式, 进入完全 2G射频工作待机状态。 步骤 307: GSM制式下根据系统信息中的 TD邻区配置, 利用 Gap时间 进行对应的 TD小区测量评估。 步骤 308: 判断 GSM制式下测量评估是否发现满足驻留的 RSCP门限条 件的 TD小区, 如果是, 转到步骤 309; 如果否, 则转到步骤 305。
步骤 309: 将找到的 TD小区推荐给 TD制式射频, 等待对其进行重选驻 留。
步骤 310: TD小区进行制式内重选动作, 更新小区重选候选列表, 按照 信号强弱依次发起重选动作。
步骤 311 : 判断当前是否找到更好的 TD小区, 完成重选驻留, 如果是, 转到步骤 312; 如果否, 转到步骤 310, 继续 TD小区重选。
步骤 312: 更新记录新驻留 TD小区对应的 GSM邻区配置信息。
步骤 313: 本次流程结束。
