具体地，无线资源控制模块接收所述物理链路重配置请求，校验 UMTS 陆地无线接入网下发的参数是否能支持， 能支持则通过物理链路重配置完 成上报网络。 Specifically, the RRC control module receives the physical link reconfiguration request, and verifies whether the parameters delivered by the UMTS terrestrial radio access network can be supported, and can support the reporting of the network through physical link reconfiguration.
步驟 210: UMTS陆地无线接入网启动异***测量； Step 210: The UMTS terrestrial radio access network initiates an inter-system measurement;
由于无线通信终端设备支持 2G网络， UMTS陆地无线接入网需要获取 2G小区的参数， 所以 UMTS陆地无线接入网下发测量控制消息， 用来启动 异***测量， 同时启动压缩模式。 Since the wireless communication terminal device supports the 2G network, the UMTS terrestrial radio access network needs to acquire the parameters of the 2G cell, so the UMTS terrestrial radio access network sends a measurement control message, which is used to initiate the measurement of the different system and simultaneously initiate the compression mode.
步驟 211: 查询业务类型； Step 211: Query the service type.
具体地， 无线资源控制模块向应用程序检测模块查询业务的类型。 由 于应用程序检测模块保存了***消息的数据， 如果是对宽带业务要求很高 的业务， 如高清视频、 视频电话业务， 应用程序检测模块可以针对业务的 特征、 ***广播中网络要求无线通信终端必须满足的条件及其无线通信终 端测量的结果， 进行计算， 决定是否上报相关的事件， 这里不允许上报 EVENT 3x 事件， 以保证高宽带要求的业务能在 3G网络下的应用。 Specifically, the RRC module queries the application detection module for the type of service. Since the application detection module saves the data of the system message, if it is a service that requires high bandwidth services, such as high-definition video and video telephony services, the application detection module can address the characteristics of the service, and the network requirements of the system broadcast must be required for the wireless communication terminal. The condition of the measurement and the result of the measurement by the wireless communication terminal are calculated to determine whether to report the related event. The EVENT 3x event is not allowed to be reported here to ensure that the service required by the high bandwidth can be applied under the 3G network.
步驟 212: 通知查询结果； Step 212: Notifying the query result;
具体地， 应用程序检测模块向无线资源控制模块通知业务检测的结果。 步驟 213: 上报结果；
具体地， 无线资源控制模块通过应用程序检测模块检测的结果， 自主 的决定是否上报 EVENT 3x事件。 Specifically, the application detection module notifies the radio resource control module of the result of the service detection. Step 213: Report the result; Specifically, the RRC module determines whether to report the EVENT 3x event autonomously by detecting the result of the module detection by the application.
步驟 214: 下发异***切换命令； Step 214: Send a different system switching command;
具体地， UMTS陆地无线接入网如果接收到了 EVENT 3x事件， 会下 发异***切换命令到无线资源控制， 主导无线通信终端进行***间切换动 作。 Specifically, if the UMTS terrestrial radio access network receives the EVENT 3x event, it will send a different system handover command to the radio resource control, and the leading radio communication terminal performs the inter-system handover operation.
步驟 215: 存储服务域信息； Step 215: Store service domain information.
具体地， 无线资源控制模块启动***间切换， 向用户识别模块保存无 线通信终端的注册信息和网络信息， 即域信息和 UMTS陆地无线接入网的 配置信息。 Specifically, the radio resource control module initiates inter-system handover, and the subscriber identity module stores registration information and network information of the radio communication terminal, that is, domain information and configuration information of the UMTS terrestrial radio access network.
步驟 216: 无线资源控制去激活 3G的接入功能， 接入 2G网络。 Step 216: The radio resource control deactivates the access function of the 3G and accesses the 2G network.
