发送请求Lai消息给底层，然后处理反馈信息取出cell_id。然后处理反馈信息取出cell_id。再根据cell_id去数据库查经纬度了。


注册消息处理函数

 void  GetCellIDStartReq(U32 mod_id, PU8 info_req)
 {
         SetProtocolEventHandler(parsing_cellId_data,MSG_ID_MMI_EM_STATUS_IND);
         get_cellid_send_start_req();
 }

发消息请求cell id

 void  get_cellid_send_start_req( void )
 {
     MYQUEUE Message;
     mmi_em_update_req_struct *em_start_req;
     Message.oslMsgId = MSG_ID_MMI_EM_UPDATE_REQ;
     em_start_req = OslConstructDataPtr(sizeof (mmi_em_update_req_struct));
 em_start_req->mod_id = MOD_AS;
     em_start_req->info_request = RR_EM_LAI_INFO;

     Message.oslDataPtr = (oslParaType*) em_start_req;
     Message.oslPeerBuffPtr = NULL;
     Message.oslSrcId = MOD_MMI;
     Message.oslDestId = MOD_L4C;
     OslMsgSendExtQueue(&Message);
 }

处理消息的回调函数

 void  parsing_cellId_data( void  *info)
 {
     mmi_em_status_ind_struct *msg = (mmi_em_status_ind_struct*) info;
     if (msg->em_info == RR_EM_LAI_INFO){
         rr_em_lai_info_struct *data_ptr;
         kal_uint16 mm_pdu_len;
         data_ptr = (rr_em_lai_info_struct*) get_pdu_ptr(msg->info,   &mm_pdu_len);
      }
 }
