摘要： A method and apparatus for mitigating the impact of lost data due to cell reselection for mobile stations operating in packet data transfer mode is described. A mobile station may perform cell reselection 2 to 4 times per minute when located in an urban area, even if the mobile station remains stationary. A mobile station moving through a communications network (100) may cross over various cell and routing area boundaries. Further, a mobile station operating in push-to-talk mode may lose up to 8 seconds of data when reselecting a cell in a new routing area. A serving cell transmits an information element (301, 303, 305) in which the mobile station is informed whether cells in its neighbor list are in the same routing area as its serving cell. If the radio link to the serving cell is acceptable then the mobile station avoids reselection to cells outside its serving cell routing area.

摘要： A method (200) for selecting a core network for a wireless communication device includes the steps of: receiving (220) at least one core network identifier; selecting (230) a core network identifier to form a selected core network identifier; setting (215) an indicator to indicate whether a substitute core network is allowed; determining (240) whether the selected core network identifier corresponds to a shared network; forming a registration request message containing the selected core network identifier; including (243) the indicator in the registration request message; and transmitting the registration request message.

摘要： A wireless communication system (100) is configured to send signaling messages through a cell broadcast service (CBS). CBS message pages used to transport signaling messages are identified by assigned message identifiers. Mobile devices (114) within the communication system (100) recognize the CBS messages transporting signaling messages by the message identifiers and pass the signaling messages to an appropriate application or control program module. The message identifier may be used to specify the application or control program module to process the signaling message. The signaling messages transported by the CBS may be used in controlling a multicasting or broadcasting service. Duplicate copies of the CBS message pages may be transmitted and then buffered at the mobile device (114) as they are received until all parts of the signaling message have been received.

摘要： A method of routing a message in a network includes transmitting by a mobile station ( 105 ) a signaling connection establishment message ( 308 ) on a radio connection to a radio network controller ( 102 ) though a base station ( 104 ). The signaling connection establishment message can include a registration request message. Next the mobile station can receive a registration accept message ( 310 ) on the radio connection and can subsequently transmit an uplink signaling message ( 312 ) on the radio connection. The uplink signaling message from the mobile station can include a core network operator identifier ( 604 ).

摘要： A method for access network (112) sharing, for example, a GSM or UMTS 3G wireless communications radio access network (RAN), among multiple core networks (120, 12, 124 & 126), for example, wireless communications services networks, including transmitting information about the core network sharing the common access network, e.g., a pseudo network identity or the number of core networks sharing the common access network or pointer information, in a system information message. The communication device (102) uses the information provided in the system information message to connect to a core network.
