步骤 53: 对 LTE邻区进行指定频点搜索或者指定小区 ID搜索, 找到 LTE 小区后, 把分组域驻留到 LTE小区。
步骤 6: 针对类型 2的终端, 则进行下面步骤:
步骤 61: 把分组域驻留到 TD-SDMA小区;
步骤 62: 终端获取 TD-SCDMA服务小区上的 GSM邻区信息;
步骤 63:对 GSM邻区进行指定频点搜索或者指定小区 ID搜索,找到 GSM 小区后, 把电路域驻留到 GSM小区。
步骤 7: 在电路域进行 GSM小区搜索, 同时在分组域进行 LTE小区搜索。 在电路域进行 GSM小区搜索, 同时在分组域进行 LTE小区搜索, 之后分 别在电路域驻留在 GSM小区, 分组域驻留在 TD-LTE小区。
图 4显示了本发明实施例提供的一种单卡多待移动终端开机时双域驻留速 度的装置示意图, 包括:
找网模块, 用于管理所有网络制式的扫频和小区搜索, 开机时优先进行 TD-SCDMA制式下扫频和小区搜索, 驻留 TD-SCDMA成功后转至邻区信息存 储模块和驻留模块; 驻留 TD-SCDMA不成功则直接进行 TD-LTE和 GSM网络 搜索;
驻留模块, 用于管理电路域和分组域的网络驻留;
邻区信息存储模块, 用于存储 TD-SCDMA小区下的 LTE和 GSM邻区信 息。
也就是说, 找网模块可以管理所有制式上的找网, 首先优先搜索 TD-SCDMA网络, 在搜索 TDS网络成功后, 由驻留模块来分别将类型 1和类 型 2的终端的电路域和分组域驻留到 TD-SCDMA网络, 并将 TD-SCDMA的 LTE邻区和 GSM邻区存储在邻区存储模块, 提供给找网模块使用。
下面以 TD-LTE/TD-SCDMA/GSM三模类型 1的单卡双待终端为例, 如图 4 所示, 说明本发明 的 实施方式, 当 然, 本发明并不局限于 TD-LTE/TD-SCDMA/GSM三模类型 1模式。在 TD-LTE/TD-SCDMA/GSM三模 类型 1单卡双待终端的实施例中,终端开机成功后, TD-LTE和 TD-SCDMA/GSM 将同时待机, TD-LTE为终端分组域提供高速数据业务, TD-SCDMA/GSM为终 端电路域提供高质量话音业务。 如图 5所示, 具体包括以下步骤:
步骤 1 : 单卡双待移动终端开机并进入覆盖区;
步骤 2: 判断终端是否已经存在驻留的 TD-SCDMA小区信息;
若终端已经存在驻留的 TD-SCDMA小区信息, 则进行 D-SCDMA小区指 定频点搜索或者指定小区 ID 搜索, 并转至步骤 4 ; 若终端存在驻留的 TD-SCDMA小区信息, 则进入步骤 3。
步骤 3: 终端进行 TD-SCDMA制式下的频段扫频; 终端进行 TD-SCDMA 制式下的频段扫频可以首先搜索 A 频段 ( 2010-2025MHZ );
步骤 4: 判断是否找到合适 TD-SCDMA小区;
若找到合适的 TD-SCDMA小区, 以类型 1为例, 则进入步骤 5; 若没有找 到合适的 TD-SCDMA小区, 则转至步骤 6;
步骤 5: 将电路域驻留到 TD-SCDMA网络, 在终端获取 TD-SCDMA小区 上的 SIB19中 TD-LTE邻区信息后, 利用 TD-LTE邻区信息对 TD-LTE进行指 定频点或者指定小区进行小区搜索, 成功找到 TD-LTE小区后并将分组域驻留 到 TD-LTE网络。
步骤 6: 在电路域进行 GSM小区搜索, 同时在分组域进行 LTE小区搜索。 在电路域进行 GSM小区搜索, 同时在分组域进行 LTE小区搜索, 搜索之 后分别在电路域驻留在 GSM小区, 分组域驻留在 TD-LTE小区。
综上所述, 本发明具有以下技术效果:
本发明能够有效的节省开机后双域找网的时间, 尤其是在终端处于第一次 开机或者是漫游到异地开机的场景下, 可以有效地利用邻区信息加快双域的驻 留和小区搜索。
尽管上文对本发明进行了详细说明,但是本发明不限于此, 本技术领域技 术人员可以根据本发明的原理进行各种修改。 因此, 凡按照本发明原理所作的 修改, 都应当理解为落入本发明的保护范围。
