Abstract: Embodiments of the present invention include methods, terminals and circuits for updating provisioning data of a mobile terminal. A network initiated subsequent provisioning message requesting that the mobile terminal initiate a session to update the provisioning data of the mobile terminal is received and it is determined if the mobile terminal is executing a foreground data application utilizing a current registered Internet Protocol (IP) session. An IP session is selectively initiated to update the provisioning data of the mobile terminal based on the determination of whether the mobile terminal is executing a foreground data application utilizing a current registered IP session.

Abstract: A system and method for determining if a mobile phone is in a home area that does not rely exclusively on the HPLMN data programmed into the mobile phone. To determine whether the mobile phone is in a home area or in a roaming area a processor in the mobile phone checks the PLMN control information in an over-the-air received signal. If the PLMN data matches the PLMN data stored in the mobile phone SIM card IMSI file, then the current network is a home network. Otherwise, the received LAI control data is checked to see whether it matches any LAI data in the OPL file of the SIM card in the mobile phone. If the received LAI data does not match any LAI data in the OPL file, then the network is not a home network but a roamed into network. If the received LAI data does match LAI data in the OPL file, then the OPL file is further examined to see whether the PNN record that the OPL record points to is the first record in the PNN file. If it is, then the network is a home network.

Abstract: A method of storing an e-mail address within an Abbreviated Dialing Number (ADN) record of a Subscriber Identity Module (SIM) card is provided. The ADN record typically includes a plurality of fields having personal contact information relating to a contact stored in the ADN record. The inventive method includes the steps of allocating a first number of bytes of memory space to a first field in the ADN record, storing an e-mail address of a contact in the first field in the ADN record, and setting a flag in a second field in the ADN record indicating a presence of a e-mail address in the first field in the ADN record.

Abstract: A system and method for preventing the unauthorized use of improperly obtained mobile equipment is disclosed. The mobile equipment includes a plurality of personalization categories that are programmable into the mobile equipment by the manufacturer. Prior to purchase and at the request of the network provider, at least one of the personalization categories in addition to the network personalization category is enabled in the mobile equipment by the manufacturer. Upon powering up the mobile equipment for the first time, a personalization check is performed for the plurality of personalization categories. The personalization check is destined to fail with respect to one of the personalization categories other than the network personalization category. At this point, the person attempting to activate the mobile equipment is prompted for the authorization code for the personalization category that failed.

Abstract: In a mobile station used in a cellular mobile telecommunication system that communicates on any one of a plurality of base station cellular channels depending on cell location of the mobile station, the system being adapted to selectively determine one of the channels to process a call with the mobile station and handoff a cellular call with the mobile station from a current channel to a new channel, a handoff system for detecting system and capability changes when a handoff has occurred. The handoff system includes a memory storing data representing parameters associated with the current channel. A forward communication channel is associated with the current channel for receiving data from a base station. The data includes a handoff message if a handoff is to occur. The handoff message includes parameters associated with the new channel.

Abstract: A method and system used in a wireless network that provides communication service on both analog control channels (ACCs) and digital control channels (DCCHs) controls access to wireless services by a mobile station. The method comprises the steps of acquiring wireless services on a select ACC; periodically receiving a pointer to a preferred DCCH as part of a message received from the wireless network via the ACC; initially attempting to acquire wireless service on the preferred DCCH, including determining if received signal strength is acceptable and available service features are acceptable, and if not, then indicating the preferred DCCH as rejected; storing information on the rejected DCCH; and subsequently attempting to acquire wireless service on the rejected DCCH only if the DCCH was rejected due to received signal strength not being acceptable.
