mt2503 mt6261平台不插SIM卡无信号

[DESCRIPTION]
在61之前平台，即使不插SIM卡，默认会以SIM 1去注册网络显示信号，以可拨打紧急电话。但在61平台，不插SIM卡，则不再显示信号。
[SOLUTION]
在61平台以下函数代码做了改动：
static void MMI_nw_info_signal_set_strength(
mmi_sim_enum sim,
S32 strength_in_percentage)
{
/*----------------------------------------------------------------*/
/* Local Variables */
/*----------------------------------------------------------------*/
S32 percent = strength_in_percentage;
S32 mainLCD_icon_id = STATUS_ICON_INVALID_ID,
sublcd_icon_id = STATUS_ICON_INVALID_ID;
srv_nw_info_service_availability_enum service_availability = srv_nw_info_get_service_availability(sim);
/*----------------------------------------------------------------*/
/* Code Body */
/*----------------------------------------------------------------*/
mmi_nw_info_signal_get_icon_id(
sim,
&mainlcd_icon_id,
&sublcd_icon_id);
/*下面这个判断即是判断没插SIM卡，或不是full service状态，就将信号格的percent置为0 */
if (！srv_sim_ctrl_is_inserted(sim) || service_availability ！= SRV_NW_INFO_SA_FULL_SERVICE)
{
percent = 0;
}
/*客户若要不插SIM卡显示信号，可将此代码去掉*/
MMI_TRACE(MMI_NW_INFO_TRC_GROUP, TRC_MMI_NW_INFO_SIGNAL_ICON_CHANGED,
sim, percent);
wgui_status_icon_bar_change_icon_level(mainlcd_icon_id, percent);
if (sublcd_icon_id ！= STATUS_ICON_INVALID_ID)
{
wgui_status_icon_bar_change_icon_level(sublcd_icon_id, percent);
}
wgui_status_icon_bar_update();
}

手机不插SIM要求能拨打紧急电话，这好像是全世界运营商的要求吧?

SandFoam大神，以后遇到困难还请多多指教
