Description

说 明 书 通信系统、 终端和通信方法
技术领域
本发明涉及终端技术领域， 具体而言， 涉及一种通信系统、 一种终端 和一种通信方法。 背景技术
针对多模单待手机， 可以支持 LTE\TD\WCDMA\GSM 等多个网络通 信， 但在同一时刻， 只有一种网络制式可以工作同时也支持 CSFB ( Circuit Switched Fallback, 电路域回落） 。 如果按照默认优先选网， 则 一般会 4G网络优先， 此时会驻留在 4G网络。
现有方案存在一个问题， 在不支持 CSFB 的区域， 驻留 4G 网络的情 况下， 有电话呼入会提示占线， 导致漏接电话。
因此， 需要一种新的技术方案， 可以避免在不支持 CSFB 的区域用户 漏接电话。 发明内容
本发明正是基于上述问题， 提出了一种新的技术方案， 可以避免在不 支持 CSFB的区域用户漏接电话。
有鉴于此， 本发明提出了一种通信系统， 用于终端， 包括： 第一通信 模块； 第二通信模块； 第一判断单元， 根据终端的实时状态， 判断所述终 端当前是否支持电路域回落； 处理单元， 在所述第一判断单元的判断结果 为是时， 建立所述第一通信模块和第一网络之间的连接， 在所述判断单元 的判断结果为否时， 建立所述第二通信模块和第二网络之间的连接。
在该技术方案中， 第一通信模块仅支持数据业务， 第二通信模块至少 支持语音业务。 在终端不支持电路域回落时， 建立第二通信模块和第二网 络的连接， 在终端支持电路域回落时， 建立第一通信模块和第一网络的连 接， 这样， 在终端不支持电路域回落时， 将网络驻留在可以进行语音业务 的第二网络， 保证语音业务优先， 从而避免用户漏接来电。
具体来说， 第一网络可以是 4G网络， 第二网络可以是 2G/3G网络。 当终端选网时， 一般会优先选择 4G 网络驻留， 这样， 在终端不支持电路 域回落时， 如果终端接收到语音业务， 则终端不能进行处理， 此时就会提 示占线， 造成用户漏接电话。 而本发明在检测到不支持电路域回落时， 将 网络驻留到支持语音业务的网络， 如 2G/3G 网络， 从而避免用户漏接电 话， 提升用户的使用体验。
在上述技术方案中， 优选地， 还包括： 第二判断单元， 用于检测所述 终端的当前的网络设置， 并判断所述当前的网络设置是否为优先建立所述 第一通信模块和所述第一网络之间的连接； 控制单元， 在所述第二判断单 元的判断结果为是时， 控制所述第一判断单元根据所述终端的所述实时状 态， 判断所述终端当前是否支持电路域回落。
在该技术方案中， 如果当前网络设置不是优先选择第一网络 （如 4G 网络） ， 比如是优先选择第二网络（如 2G/3G网络） ， 那么终端可以继续 驻留在第二网络， 不需要判断是否支持电路域回落， 而如果终端优先选择 第一， 此时再判断终端是否支持电路域回落， 这样， 可以针对终端的不同 情况进行不同的操作， 避免终端资源的浪费。
在上述技术方案中， 优选地， 所述实时状态包括： 所述终端的网络注 册状态和所述终端的实时工作状态。
在该技术方案中， 可以根据终端的网络的注册状态和终端的工作状态 判断终端是否支持电路域回落， 如当前注册到的网络是第一网络和 /或第 二网络， 当前终端是否可处理语音业务和 /或数据业务。 本领域技术人员 应当理解， 判断终端是否支持电路域回落的方式包括但是不限于上述两 种。

在该技术方案中， 在判断终端是否支持电路域回落时， 可以通过判断 终端的联合注册结果来实现。 当终端在开机时， 可能发起联合注册， 即同 时注册第一网络和第二网络， 如同时注册 4G和 2G/3G网络， 如果注册结 果为 4G和 2G/3G网络都注册成功， 则说明支持电路域回落。 如果注册结 果为只有 4G网络注册成功， 即返回 EPS only的信息， 则说明不支持电路 域回落。

在该技术方案中， 如果判断出终端不支持电路域回落， 先判断一下终 端当前终端是不是正在处理数据业务， 如果终端正在处理数据业务， 此时 若直接将数据业务中断， 将网络驻留在第二网络， 会影响用户的使用体 验， 因此， 在判断出终端在处理数据业务时， 提示用户， 让用户选择是否 断开数据业务， 将网络驻留在可以处理语音业务的第二网络， 这样， 既可 以保证数据业务不受影响也可以保证语音业务的正常进行， 更提升了用户 的使用体验。
在上述技术方案中， 优选地， 还包括： 功能控制单元， 用于根据接收 到的功能开启和 /或功能关闭命令， 开始和 /或停止根据所述终端的实时状 态， 判断所述终端当前是否支持电路域回落。

图 2示出了根据本发明的实施例的通信方法的流程图。
如图 2所示， 根据本发明的实施例的通信方法， 包括： 步骤 202 , 根 据所述终端的实时状态， 判断所述终端当前是否支持电路域回落； 步骤 204 , 在判断结果为所述终端当前支持所述电路域回落时， 建立所述第一 通信模块和第一网络之间的连接， 在所述判断单元的判断结果为否时， 建 立所述第二通信模块和第二网络之间的连接。
在该技术方案中， 第一通信模块仅支持数据业务， 第二通信模块至少 支持语音业务。 在终端不支持电路域回落时， 建立第二通信模块和第二网 络的连接， 在终端支持电路域回落时， 建立第一通信模块和第一网络的连 接， 这样， 在终端不支持电路域回落时， 将网络驻留在可以进行语音业务 的第二网络， 保证语音业务优先， 从而避免用户漏接来电。
具体来说， 第一网络可以是 4G网络， 第二网络可以是 2G/3G网络。 当终端选网时， 一般会优先选择 4G 网络驻留， 这样， 在终端不支持电路 域回落时， 如果终端接收到语音业务， 则终端不能进行处理， 此时就会提 示占线， 造成用户漏接电话。 而本发明在检测到不支持电路域回落时， 将 网络驻留到支持语音业务的网络， 如 2G/3G 网络， 从而避免用户漏接电 话， 提升用户的使用体验。
在上述技术方案中， 优选地， 还包括： 检测所述终端的当前的网络设 置， 并判断所述当前的网络设置是否为优先建立所述第一通信模块和所述 第一网络之间的连接； 在判断结果为所述当前的网络设置为优先建立所述 第一通信模块和所述第一网络之间的连接时， 根据所述终端的所述实时状 态， 判断所述终端当前是否支持电路域回落。
在该技术方案中， 如果当前网络设置不是优先选择第一网络 （如 4G 网络） ， 比如是优先选择第二网络（如 2G/3G网络） ， 那么终端可以继续 驻留在第二网络， 不需要判断是否支持电路域回落， 而如果终端优先选择 第一， 此时再判断终端是否支持电路域回落， 这样， 可以针对终端的不同 情况进行不同的操作， 避免终端资源的浪费。
在上述技术方案中， 优选地， 所述实时状态包括： 所述终端的网络注 册状态和所述终端的实时工作状态。
在该技术方案中， 可以根据终端的网络的注册状态和终端的工作状态 判断终端是否支持电路域回落， 如当前注册到的网络是第一网络和 /或第 二网络， 当前终端是否可处理语音业务和 /或数据业务。 本领域技术人员 应当理解， 判断终端是否支持电路域回落的方式包括但是不限于上述两 种。
在上述技术方案中， 优选地， 根据所述终端的实时状态， 判断所述终 端当前是否支持电路域回落， 包括： 在所述第一通信模块和所述第二通信 模块分别启动注册到所述第一网络和所述第二网络时， 获取注册结果； 当 所述注册结果为所述注册到所述第一网络成功且注册到所述第二网络失败 时， 判定为所述终端当前不支持所述电路域回落， 否则， 判定为所述终端 当前支持所述电路域回落。
在该技术方案中， 在判断终端是否支持电路域回落时， 可以通过判断 终端的联合注册结果来实现。 当终端在开机时， 可能发起联合注册， 即同 时注册第一网络和第二网络， 如同时注册 4G和 2G/3G网络， 如果注册结 果为 4G和 2G/3G网络都注册成功， 则说明支持电路域回落。 如果注册结 果为只有 4G网络注册成功， 即返回 EPS only的信息， 则说明不支持电路 域回落。
在上述技术方案中， 优选地， 根据所述终端的实时状态， 判断所述终 端当前是否支持电路域回落， 还包括： 判断在所述终端接收到的跟踪区更 新消息中是否包含指定类型的信息； 在判断结果为不包含所述指定类型的 信息时， 判定为所述终端当前支持所述电路域回落， 否则， 判定为所述终 端当前不支持所述电路域回落。
在该技术方案中， 当终端开机时未进行联合注册， 而终端已连接到第 一网络， 如 4G 网络， 此时， 可以判断在网络返回的跟踪区更新消息中是 否包含指定类型的信息， 其中， 指定类型的信息包括 Additional update result (附加更新结果） 选项， 若在跟踪区更新消息不包含 Additional update result (附加更新结果） 选项， 或者 Additional update result选项内 容不是 0001 , 则判断为支持电路域回落， 否则为不支持。
在上述技术方案中， 优选地， 还包括： 在所述终端当前支持所述电路 域回落时， 判断所述第一通信模块和所述第一网络当前是否处于连接状 态； 当所述第一通信模块和所述第一网络当前处于连接状态时， 判断所述 第一通信模块和所述第一网络当前是否在进行数据业务； 当所述第一通信 模块和所述第一网络当前是否在进行数据业务， 提示所述终端的用户是否 断开所述第一通信模块和所述第一网络之间的连接， 并建立所述第二通信 模块和所述第二网路之间的连接， 以及当所述第一通信模块和所述第一网 络当前未进行数据业务时， 直接断开所述第一通信模块和所述第一网络之 间的连接， 并建立所述第二通信模块和所述第二网络之间的连接。
在该技术方案中， 如果判断出终端不支持电路域回落， 先判断一下终 端当前终端是不是正在处理数据业务， 如果终端正在处理数据业务， 此时 若直接将数据业务中断， 将网络驻留在第二网络， 会影响用户的使用体 验， 因此， 在判断出终端在处理数据业务时， 提示用户， 让用户选择是否 断开数据业务， 将网络驻留在可以处理语音业务的第二网络， 这样， 既可 以保证数据业务不受影响也可以保证语音业务的正常进行， 更提升了用户 的使用体验。
在上述技术方案中， 优选地， 还包括： 根据接收到的功能开启和 /或 功能关闭命令， 开始和 /或停止根据所述终端的实时状态， 判断所述终端 当前是否支持电路域回落。
在该技术方案中， 用户可以根据个人需要选择开启和关闭本发明的上 述语音业务优先的功能， 在开启时， 则在不支持电路域回落时， 会将终端 驻留在可以处理语音业务的第二网络， 在关闭时， 终端则不会进行上述操 作， 从而方便用户根据不同的场合和不同的需要进行不同的功能选择。
下面以第一网络是 4G网络， 第二网络是 2G/3G网络为例， 详细说明 本发明的技术方案。 图 3示出了根据本发明的实施例的通信方法的具体流程图。 如图 3所示， 根据本发明的实施例的通信方法的具体流程如下： 步骤 302 , 检测用户选网设置。
步骤 304, 判断当前选网设置是否是 4G网络优先。
步骤 306, 如果当前选网设置是 4G 网络优先， 则检测终端的核心网 是否支持 CSFB功能。 其中， 判断核心网是否支持 CSFB有两种办法： 一 种是开机进行联合注册时， 若核心网不支持 CSFB 功能， 则会返回 EPS Only; 另一种方法是根据小区下发的配置信息来判断是否支持 CSFB 功 能。
步骤 308, 如果当前网络不支持 CSFB 功能， 或者当前选网设置为不 支持 4G优先时， 则驻留到 2G/3G网络。
步骤 310, 如果当前网络支持 CSFB功能， 则驻留到 4G网络。
图 4示出了根据本发明的实施例的电路域回落判断的具体流程图。 如图 4 所示， 根据本发明的实施例的电路域回落判断的具体流程如 下：
步骤 402 , 判断终端在是否在刚开机进行注册。 在判断结果为是时， 进入步骤 404, 在判断结果为否时， 进入步骤 408。
步骤 404 , 终端发起联合注册。 即同时注册多个网络， 如同时注册 2G/3G/4G网络。
步骤 406, 判断联合注册的结果是否为只能注册指定网络， 如只能注 册 4G 网络， 不能注册 2G/3G网络。 在判断结果为是时， 进入步骤 412 , 在判断结果为否时， 进入步骤 414。
步骤 408 , 分析小区下发的配置信息。
步骤 410, 判断小区下发的配置信息中是否包含 CSFB 配置信息。 具 体判断过程为： 在 2G/3G 下， UE 底层一直在做测量， 若发现合适的 4G 网络小区， 会将该 4G网络的小区信息上报给 UE高层， 然后， UE高层结 合当前系统消息里配置的重选参数， 判断该 4G 网络小区是否满足驻留条 件， 若 4G 小区满足驻留条件， 则会重选到该 4G 网络小区。 只有当 UE 驻留在 4G网络， 并发起 TAU(Tracking Area Update , 跟踪区更新）过程， 网络在返回的 TAU accept (跟踪区更新接受） 消息中才会携带是否支持 CSFB 的参数。 网络在 TAU accept 消息中若没有携带 Additional update result (附加更新结果） 选项， 或者 Additional update result选项的内容不 是 0001 , 都表示网络支持 CSFB。
步骤 412 , 判定为支持 CSFB功能。
步骤 414, 判定为不支持 CSFB功能。
图 5示出了根据本发明的一个实施例的通信方法的流程图。
如图 5所示， 当终端从支持 CSFB的区域移动到不支持 CSFB的区域 时， 处理流程如下：
步骤 502 , 判断用户当前是否使用数据业务。 在判断结果为是时， 进 入步骤 504, 在判断结果为否时， 进入步骤 506。
步骤 504, 提示用户可能会漏接电话， 是否切换驻留的网络。
步骤 506, 在用户当前未使用数据业务或者在用户选择切换驻留网络 时， 将网络驻留在 2G/3 G网络。
以上结合附图详细说明了本发明的技术方案， 通过本发明的技术方 案， 在终端不支持电路域回落时， 将网络驻留在可以进行语音业务的第二 网络， 保证语音业务优先， 从而避免用户漏接来电。
