Mar 14, 2006 DR: OMAPS00061468 - x0035544. Description: SAT 27.22.4.22.2 SET UP IDLE MODE TEXT (Icon support) fails Solution : In the function homezoneUpdateDisplay(), additional parameter has been added to the function call addSatMessage() under the flag FF_MMI_SAT_ICON to support SAT Icon for IDLE TEXT display. Dec 15, 2005 REF: MMI-FIX-OMAPS00058684 x0035544 Description: OMAPS00045726 / MMI-FIX-30439 Follow-Up : ifdef for FF Home Zone forgotten. Solution: Added Feature flag FF_HOMEZONE for the function sms_homezoneCBToggle(U8 Activate_CB) in this file as it has got the prototype for this function. Jun 14, 2005 REF: MMI-FIX-30439 x0018858 Description: The homezone/cityzone tags were not being displayed properly. Solution: Modified to save the tags properly in caches and also made the appropriate modifications to update the same properly during mobility. $End *******************************************************************************/ #include <string.h> #include <stdio.h> #include <stdlib.h> #if defined (NEW_FRAME) #include "typedefs.h" #include "vsi.h" #include "pei.h" #include "custom.h" #include "gsm.h" #else #include "STDDEFS.H" #include "custom.h" #include "gsm.h" #include "vsi.h" #endif #include "mfw_sys.h" #include "mfw_mfw.h" #include "mfw_win.h" #include "mfw_kbd.h" /* SPR#1428 - SH - New Editor changes */ #ifndef NEW_EDITOR #include "mfw_edt.h" #endif #include "mfw_lng.h" #include "mfw_icn.h" #include "mfw_phb.h" #include "mfw_sim.h" #include "mfw_nm.h" #include "ksd.h" #include "psa.h" #include "mfw_sms.h" #include "mfw_smsi.h" #include "mfw_mnu.h" #include "mfw_sat.h" #include "mfw_tim.h" #include "mfw_cphs.h" #include "MmiMmi.h" #include "MmiDummy.h" #include "MmiDialogs.h" #include "MmiLists.h" #include "MmiMain.h" #include "MmiStart.h" #include "MmiPins.h" #include "MmiMenu.h" #include "MmiSoftKeys.h" #include "MmiSounds.h" #include "mmiCall.h" #include "MmiBookController.h" #include "MmiIdle.h" #include "Mmiicons.h" #include "MmiNetwork.h" #include "mmiSmsBroadcast.h" #include "MmiHomezone.h" #include "cus_aci.h" #include "prim.h" #ifndef PCM_2_FFS #include "pcm.h" #endif //Jun 14, 2005 REF: MMI-FIX-30439 x0018858 // enable HZ trace //#undef TRACE_MMIHOMEZONE #define TRACE_MMIHOMEZONE 1 T_homezone_data homezoneData; extern T_SMSCB_DATASTORE g_smscb_data; /* storage for Cell Broadcast lists */ static int hzFlag = 0; //Jun 14, 2005 REF: MMI-FIX-30439 x0018858 //Dec 14, 2005 REF: MMI-FIX-OMAPS00058684 x0035544 #ifdef FF_HOMEZONE //Jun 14, 2005 REF: MMI-FIX-30439 x0018858 // Externed the function for activation\deactivation of Homezone. extern void sms_homezoneCBToggle(U8 Activate_CB); #endif /* x0039928 - Lint warning fix */ static char *homezoneMNC_MCC[HZ_PERMITTED_NETWORKS] = { "26207", /* VIAG Interkom */ }; //void sms_homezoneCBToggle(U8 Activate_CB); /******************************************************************************* LOCALLY REFERENCED FUNCTIONS *******************************************************************************/ void homezoneReadParams(); void homezoneLocate(); static U32 calculateDecimal( char *string, int length ); static U32 readHexFromSimfile( UBYTE *simFile, int length ); static void writeHexToSimfile( UBYTE *simFile, U32 value, int length ); /******************************************************************************* $Function: homezoneInit $Description: Initialise homezone data structure.
