Abstract:
A method and apparatus for broadcast subscription management in a mobile station (110) comprises sending (302) a subscriber identifier, which may be for example an international mobile station identifier and a radio receiver identification with a transmitter of the mobile station to a wireless communications network (100). The mobile station receives, from a Broadcast Network Operator (187), through the wireless communications network, a shared secret key. The mobile station authenticates (306) a broadcast radio receiver of the mobiles station or broadcast data received from the broadcast network operator with the shared secret key.
Abstract:
The present invention provides a method for managing in a mobile subscriber the traffic flow of a communication connection during a cell reselection. The method includes communicating via a communication connection with a first cell, and monitoring communication conditions, while communicating with the first cell. An approximate time is then determined, when conditions associated with the flow of communication via the communication connection with the first cell is consistent with transferring the flow of communication to a communication connection with a second cell. The mobile subscriber then establishes a communication connection with the second cell, while maintaining the communication connection with the first cell. The method further includes routing the flow of the communication from the communication connection with the first cell to the communication connection with the second cell, and releasing by the mobile subscriber the communication connection with the first cell, proximate the time that the flow of communication is routed from the communication connection with the first cell to the communication connection with the second cell.
Abstract:
A method (500, 600) and apparatus (200) for handover of a communication device (120) between a first network (130) and a second network (140) while the communication device is in an ongoing communication. The communication device can register with the second network (610). The communication device can also enter an ongoing communication via the first network (620). The communication device can send a transfer request to the second network to request a handover of the ongoing communication between the first network and the second network without interrupting the ongoing communication (640).
Abstract:
A method and apparatus method of filtering packet data for an anonymous user device in a packet data network communication system includes a first step of defining a special context information element containing special context information. A next step includes sending the special context information element in an activate packet data protocol (PDP) context request to a network to initiate a call from an anonymous user device. A next step includes configuring the data packets so that only the special context is allowed. A next step includes assigning an interim IP address to the user device. A next step includes mapping the data packets of the configuring step to the interim IP address of the user device. A next step includes defining permissible routing identities per the special context. A next step includes routing the data packets between only those permissible routing identities from the defining step.
Abstract:
The present invention provides a communication controller and a method (fig. 7) for maintaining a communication connection during a cell reselection. The communication connection is maintained by changing between a first operating mode (308), such as a packet data mode, which does not support the maintenance of a communication connection throughout a cell reselection (310), and a second operating mode, such as a circuit switched mode, which does support maintenance of a communication connection during a handover. Use of a virtual mobile switching center in the base station subsystem facilitates the conversion and routing of circuit switched data, transmitted between the mobile subscriber and the base transceiver station, to the packet data network while in a circuit switched mode.
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.
Abstract:
A method and apparatus of filtering packet data for an anonymous user device in a packet data network communication system (Fig.3) includes a first step of initiating a call from an anonymous user device on a home network (30). A next step includes assigning an interim identity and interim IP address to the user device (36). A next step includes determining a level of service access of the data packets from the user device (34). A next step includes mapping the level of service access of the user device to the IP address. A next step includes defining permissible routing identities per the level of service access (40). A next step includes routing the data packets of the call along with the associated IP address to only those location addresses from the defining step (42).
Abstract:
An apparatus (100) and method (300, 400) for primary link packet control using a traffic flow template. Primary link traffic flow template filter parameters can be set at a packet control module (120). Incoming packet data can be compared against the primary link traffic flow template filter parameters (340). How the incoming packet data is sent to a wireless device (180) over the primary link can be controlled based on comparing incoming packet data against the primary link traffic flow template filter parameters.
Abstract:
A method in a wireless communications network including receiving (310) a network connection request from a subscriber device having an invalid subscriber identity, connecting (340) the subscriber device, from which the network connection request was received, to the wireless communications network for limited purposes only upon determining (320) that the subscriber device has in invalid subscriber identity in the absence of a limited network connection indicator in the network connection request. In some embodiments, a limited attach message indicates that the attach request is for limited purposes.
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.
