其中 callcmd 在cm.h 中定义：

NAS层架构

二 REG 模块

主要作用：

2.1 选网和注册

优先级： RPLMN=>HPLMN=>other PLMN (signal quality)

2.2 手动驻网

PLMN 由用户指定

2.3 管理内容

CS/PS RAT(LTE,UMTS, 5G ,GSM)

2.4 搜网场景

漫游的时候，周期性搜网；

驻留在visiting PLMN 时候，开启定时器周期性搜网（2min--6min）

四 MBMSM 模塊

MBMS（Multimedia Broadcast Multicast Services),10年的时候当时国内比较流行多媒体电视，当时联芯都提供这些功能。

LTE eMBMS视频解决方案最适合的商业模式如下：

1、热门赛事直播，如2014年举行的巴西世界杯，奥运会、NBA等等；

2、热门电视剧直播，热点时段由OTT视频业务提供方定点定时直播热播电视连续剧；

3、频道出租，将频道分成小片段租赁给OTT视频网站；

4、将业务能力分成碎片，实现小包内业务推送，如手机报、视频手机报、热门新闻、热门音乐、股市行情、天气、运动会信息更新；

5、重大事件公布，如地震、台风、暴雨等大事件广播发布。

6、夜间整部大片推送，将热门电影以超清码率夜间推送到手机、PAD，实现按内容收费。

7、热门应用批量更新；

8、广告屏内容推送，实现广告屏幕的批量更新；

9、Push to talk，应用于警务、消防、石油勘探、调度等行业市场；

功能：

MBMS 上下文管理，最多管理16个

MBMS 服务管理：上下文激活功能，去激活功能

链路层建立

五 CB（Cell Broadcast (CB)）

T echnical Realization of Cell Broadcast Service 3GPP TS 23.041

Broadcast/MulticastControl (BMC) 3GPP TS 25.324

作用：

1：激活去激活CB监听

2：处理WMS 搜寻请求

3：执行CBS 监听

4：转发消息到WMS 模块

CB模块主要针对GSM, BMC 主要针对WCDMA
CB 和 BMC 模块跟上层的接口相同，跟底层的接口不同

六 TC模块

作用

1 激活/去激活 UE Radio Bearer Testmode

2 开启/停止 UE test loop functions (支持 BER, BLER measurements by SS, etc.)

3 上报 UE’s RLC SDU counter value
