Abstract: A wireless communication device (102) includes a processor (406) and a wireless network interface (404, 407), communicatively coupled with the processor (406), for determining the presence of a network providing wireless communication service. The device (102) also includes a memory (408) for storing a plurality of emergency service connection profiles. One of the profiles is selected based on the network determined to be present. The selected profile is then presented via a user interface (302) to a user of the wireless communication device (102) as a single emergency call model that is uniform among the profiles.

Abstract: A device (100) that includes a communications port (130), a first processor (135), at least a second processor (140), and a multiplexer (105). The multiplexer can selectively communicatively link the communications port to the first processor or the second processor. The multiplexer can include at least one switch (110, 115) and a switch controller (120) that controls operation of the switch. The switch controller can be responsive to at least one control signal (125) generated by the first processor. The first processor can generate the control signal in response to a command received from an external device (155) connected to the communications port. The command can be an attention command or a test software command. The switch controller also can be responsive to at least one control signal generated by the second processor.

Abstract: A method for determining the co-location of cell sites includes the steps of acquiring a neighbor cell list (602), monitoring the neighbor cell sites for longitude and latitude information (604). Te longitude and latitude information is used of calculating the distance and bearings between the serving and neighbor cell sites (606 and 608). Neighbor cell sites having similar bearing and distances are grouped together (610), if grouped neighbors are in close proximity, the centroid of a polygon formed by the sector vertices is determined (614) and new latitude and longitude information for the centorid is determined (616). The neighbor cell list is then modified to indicate sectored versus omni-directional sites (620) and the information is then used by the communication device to make better mobility decisions.

Abstract: A method for automatically entering a SIM's PIN in case of a reset or other condition includes the steps of storing (206) in RAM the PIN after it has been verified (204). Whenever a reset condition occurs, the PIN that is cached in RAM (106) is automatically presented to the SIM (214). In order to make sure that the PIN stored in RAM (106) in not corrupted during a reset condition, the inverse (208) or other coded form of the PIN is also stored in RAM (106) as an additional check of the correctness of the stored PIN.

Abstract: A mobile communication device (102) capable of performing non-standard communication modes, such as dispatch calling uses a subscriber identity module (SIM) (104). In order to allow the use of the non-standard, or extended features, the SIM has information for allowing use of the extended features stored therein (112). In order to determine if the SIM in the mobile communication device allows extended feature, the SIM must be checked upon initialization (202) of the mobile communication device. The mobile communication device has, stored in a non-volatile memory, a directory name or address of a feature directory in the SIM (111), and a copy of a feature signature file (111). The mobile communication device first checks to see if the directory is present (206) having the name stored in the mobile communication device, or at the address provided in the mobile communication device.

Abstract: A subscriber unit handles incoming calls routed through an old server site while in the process of switching site affiliation to a new server site (500). The subscriber unit initiates the switching of site affiliation (510), and during the process, alternates between receiving communication from the new server site (520) and receiving communication from the old server site to monitor for an incoming call (530). When an incoming call routed through the old server site is detected (540), the subscriber unit aborts or suspends the switching process and accepts the incoming call through the old server site (551, 552).
