MTK获取基站的cell_id

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);
     }
}
