  • Publication number: 20050202828
    Abstract: A wireless communication device (102), a wireless communication network and methods therefor. The wireless communication device (102) comprises a transceiver (202) configured to receive a neighbor list (216) from a remote source (108, 110, 112). The device (102) receives the neighbor list (216) that includes one or more technology type indicators and determines availability of technology based on the neighbor list. The wireless communication network comprise a server (112) and a base station (108, 110) communicating with the server. The server (112) inserts network identification and technology type to the neighbor list (216), and the base (108, 110) station provides the neighbor list to a remote device (102).

  • Publication number: 20050117540
    Abstract: 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).

  • Publication number: 20050083961
    Abstract: 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.

  • Publication number: 20050047369
    Abstract: 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.

  • Publication number: 20050037753
    Abstract: A method for a communication device to search for service from an alternate public land mobile network when a public land mobile network rejects a registration message from the communication device includes a first step of having the device roam to a visited public land mobile network (PLMN). A next step includes sending a registration message to the PLMN. A next step includes rejecting the registration message by the PLMN. This rejection can include ignoring the registration or sending an error message back to the device. A next step then includes searching for service from an alternate public land mobile network.

  • Patent number: 5761472
    Abstract: A computer system which includes a processor having an instruction set capable of "delaying" block-store instructions related to any outstanding block-load instruction(s). Accordingly, a method for interleaving block data transfers and processing steps which exploits the characteristics of the instruction set and architecture of the processor in order to increase efficiency and throughput of the computer system is provided. Hence by interleaving the block-store instruction of the previous data block with the block-load instruction of the next data block, the entire block transfer process can streamlined.
