A method, system and computer-usable medium are provide for managing the Open Channel for IMS command correctly the UICC to have knowledge about the specific status codes the ME received from IMS. This knowledge allows the UICC to make a smarter decision on what it attempts to do to access IMS. Accordingly, the UICC is provided with detailed information about the status codes from the IMS service to allow the UICC to make an informed decision. If the UICC does not have such knowledge, it is possible that the UICC will send potentially unwanted commands to the ME to establish access to IMS.

Card toolkit support for IP multimedia subsystem

To consolidate session initiation protocol (SIP) messages a user equipment (UE) is made aware of all Internet Protocol (IP) multimedia subsystem (IMS) applications installed in its memory and on a universal integrated circuit card (UICC) and supported communication services. By obtaining this information before the initial IMS Registration, the UE can save resources by registering all local applications and communication services in single IMS registration.

Card application toolkit support for IP multimedia subsystem

This application pertains to methods and apparatus to perform time zone determination by a mobile station. One example method for use in a device includes transmitting a messaging service message to a server via a communication network, the messaging service message to be used to determine a time zone for the device, and receiving the time zone for the device from the server. Other examples are shown and described.

Methods and apparatus to perform time zone determination by a mobile station

Methods and apparatus to manage mobile handover are disclosed. An example mobile station includes hardware and software stored on a tangible computer readable medium that, during operation, cause the mobile station to receive from a network controller a response to a network registration request, wherein the response includes an indicator to indicate a type of cell that may be reported by the mobile station during a handover procedure and send a handover message indicating cells permitted by the indicator.

Methods and apparatus for managing mobile handover

Methods are described for use in a mobile device such that when the mobile device is connected to a generic access network (GAN) cell, the mobile device receives information including characteristics pertaining to one or more neighbor cells in a network that are not GAN cells. The mobile device can then determine at least a list of candidate neighbor cells for handover from the GAN cell to a cell that is not a GAN cell as a function of the information. In some embodiments of the invention the network that is not a GAN is a UTRAN network and a candidate list of 3G cells are generated.

System and method for reporting of neighbour cells in handover from GAN

This application pertains to methods and apparatus to perform time zone determination by a mobile station. One example method for use in a communication device includes determining a geographical location and universal time for the device; determining a time zone for the device based on the geographical location; determining a time for the device based on the universal time and the time zone; using the determined time in applications operable on the device, wherein the applications operable on the device comprise applications other than the application used to determine the geographical location. Other examples are shown and described.
