核心服务

简介

核心服务模块主要功能是初始化SIM卡服务、搜网服务和RIL管理,以及获取RIL Adapter服务。

通过注册回调服务,实现与RIL Adapter进行通信;通过发布订阅,来实现与各功能模块的通信。

图 1 核心服务架构图

上图示中核心服务关联的业务服务包括SIM卡服务、搜网服务、RIL通信管理。

  • SIM卡服务:主要是SIM卡初始化,文件读写,加载状态通知,单双卡控制,包括SIM卡状态查询、SIM卡管理、SIM卡控制、STK、联系人存储、短信存储。
  • 搜网服务:主要是网络注册,网络状态获取,包括网络注册、网络模式查询、IMS网络状态上报、Radio状态查询、搜网管理、信号强度查询、小区管理、驻网管理、时间时区更新。
  • RIL管理:提供主动回调服务,查询结果回调服务等。

说明:

RIL管理不对外暴露接口,由电话服务子系统其他各个模块调用。

使用说明

搜网

获取网络状态接口调用流程及示例代码:

  1. 指定查询的slotId,若不指定默认查询主卡信息。

  2. 可以通过callback或者Promise的方式调用getNetworkState方法,返回网络状态信息。

  3. 该接口为异步接口,相关执行结果会从callback中返回。

    import radio from "@ohos.telephony.radio";
    
    // 参数赋值
    let slotId = 0;
    
    // 调用接口【callback方式】
    radio.getNetworkState(slotId, (err, value) => {
      if (err) {
        // 接口调用失败,err非空
        console.error(`failed to getNetworkState because ${err.message}`);
        return;
      }
      // 接口调用成功,err为空
      console.log(`success to getNetworkState: ${value}`);
    });
    
    // 调用接口【Promise方式】
    let promise = radio.getNetworkState(slotId);
    promise.then((value) => {
      // 接口调用成功,此处可以实现成功场景分支代码。
      console.log(`success to getNetworkState: ${value}`);
    }).catch((err) => {
      // 接口调用失败,此处可以实现失败场景分支代码。
      console.error(`failed to getNetworkState because ${err.message}`);
    });

SIM卡

查询指定SIM卡的状态接口调用流程及示例代码:

  1. 指定查询的slotId。

  2. 可以通过callback或者Promise的方式调用getSimState方法,返回卡状态信息。

  3. 该接口为异步接口,相关执行结果会从callback中返回。

    import sim from "@ohos.telephony.sim";
    
    // 参数赋值
    let slotId = 0;
    
    // 调用接口【callback方式】
    sim.getSimState(slotId, (err, value) => {
      if (err) {
        // 接口调用失败,err非空
        console.error(`failed to getSimState because ${err.message}`);
        return;
      }
      // 接口调用成功,err为空
      console.log(`success to getSimState: ${value}`);
    });
    
    // 调用接口【Promise方式】
    let promise = sim.getSimState(slotId);
    promise.then((value) => {
      // 接口调用成功,此处可以实现成功场景分支代码。
      console.log(`success to getSimState: ${value}`);
    }).catch((err) => {
      // 接口调用失败,此处可以实现失败场景分支代码。
      console.error(`failed to getSimState because ${err.message}`);
    });
