摘要： A communication session between a node seeking network access and a NAS (Network Access Server) is established by having only few exchanges of messages. Upon detecting a physical link between the node and the NAS, the NAS immediately sends an authentication request message to the node. In response, the node sends a request message which includes all parameters options, in addition to responding to the authentication request message, for link configuration and network access control. The NAS then picks and chooses the parameter options and sends back the selected options in a reply message to the node. If the selected options in the reply message meet a threshold, the node straightforwardly transmits user data for network access via the NAS.

摘要： Methods and apparatus are presented to reduce the number of registration requests transmitted by a mobile node to a foreign agent. Rather than always sending the re-registration request at pre-determined times before the expiry of registration lifetime, re-registration requests are transmitted only if some data transfer takes place after a time period demarcated by the previous successful registration (340).

摘要： A wireless network assigns a single IP address to the wireless device, which assigns this IP address over to a TE2 device coupled to the wireless device. The wireless device derives a private IP address for communication with the TE2 device. The wireless device forwards packets exchanged between the TE2 device and the wireless network using the single IP address. The wireless device exchanges packets with the TE2 device by (1) using the private IP address for outbound packets sent to the TE2 device and (2) performing either address-based routing or packet filtering on inbound packets received from the TE2 device. The wireless device exchanges packets with the wireless network by (1) using the single IP address for outbound packets sent to the wireless network and (2) performing packet filtering on inbound packets received from the wireless network.

摘要： In a communication system in which a roaming node seeking network access among different networks which are implemented with different network interface layer protocols, handoff schemes are instituted whereby the node may freely move from one network to another with reduced levels of interruptions with respect to the network access. Prior to and at the onset of a handoff, the node receives an indication for the handoff. The indication may be embodied in various forms such as a signal message indicating a change of the SID (System Identification), NID (Network Identification), or PZID (Packet Zone Identification). Alternatively, the indication can be in the form of information straightforwardly included in a data packet sent to the roaming node prior to the handoff. As another alternative, the indication can be implemented as distinguishable message patterns sent to the node in which different message patterns can be sent by different networks supporting different network interface layer protocols.

摘要： A generic quality of service (QoS) model that is not dependent on network technology is used to support QoS for communication networks utilizing different network technologies. The generic QoS model may include a superset of all QoS parameters for all network technologies being supported, e.g., 3GPP and 3GPP2. An application at a device may specify QoS for a traffic flow based on the generic QoS parameters in the superset. The generic QoS parameters may be converted to QoS parameters that are specific to a serving network. The converted QoS parameters are exchanged with the serving network and are used while exchanging traffic with the serving network.

摘要： A method or system (10) establishes a packet network call over a transmission link extending between a mobile terminal device (12) and an interworking function (18) which comprises a gateway or bridge connection to a network, such as a packet network. The transmission link connects the mobile terminal device (12) to a wireless communication device (14) over a first interface (Rm) and further connects the wireless communication device to the interworking function over a second interface via a wireless link (Um) to a base station (16). The packet network call, once established, comprises a first interface data link formed within a predetermined data link layer across the first interface (Rm) and a second interface data link formed within the predetermined data link layer across the second interface. A flow control is asserted (304) and deasserted (310) on the mobile terminal device (12). During the flow control, the wireless communication device performs a linked control protocol negotiation with the interworking function to establish the second interface data link with the interworking function (18). After the second interface data link is established, and during the flow control, the wireless communication device (14) performs a network control protocol negotiation with the interworking function to establish a second interface network link carried by the second interface data link.

摘要： A system and method for invoking the performance of mobile node registration in a wireless communication network. The system comprises a terminal device for transmitting and receiving packetized data and a communication device coupled to the terminal device. The communication device monitors the packetized data for an Internet Protocol (IP) address contained in an IP address request. If the IP address request is for a static IP address the communication device waits for network movement information. Based on the received network movement information, the communication device solicits network address information. Upon receipt of the network address information, the terminal device then initiates Mobile Node registration. As a result, the Mobile Node registration is automatically invoked whenever the terminal device changes its network point-of-attachment.

摘要： The packets generated by each of multiple packet data applications are provided to a single Point-to-Point Protocol (PPP) stack and a single High-level Data Link Control (HDLC) framing layer to convert data packets into byte streams suitable for transmission through Radio Link Protocol (RLP) connections. Each of the resultant multiple byte streams is then provided to one of multiple RLP connections having different retransmission and delay properties. The RLP connection selected for sending data from each application is based on the grade of service most appropriate for the application. At the receiver, the data from the multiple RLP connections is provided to a single PPP stack.

摘要： Systems and techniques for establishing a communication link wherein a transmission source delimits frame boundaries of a payload, calculates a value as a function of a subset of the payload, and appends the value to the payload within the frame boundaries before transmission of the frame. A receiving source calculates a value as a function of a subset of the payload, compares the calculated value to the received value, and detects a valid payload as a function of the comparison.

摘要： Techniques to maintain an IP session established via a first (e.g., HDR) radio network (120) while being turned to a second (e.g., cdma2000) radio network (122). During registration, configuration, and session establishment with the first and second radio networks, an access terminal (110) may be respectively assigned first and second IP addresses for use during these sessions. If the access terminal (110) leaves the first radio network (120), it can request that the IP session be maintained and provides a forwarding address. Thereafter, if the first radio network (120) has data for the access terminal (110), it sends a 'spoof' packet to the access terminal (110) using the forwarding address. The spoof packet can indicate that there is data available for the access terminal (110). Upon receiving a communication (e.g., a page) from the second radio network (122) in response to the spoof packet, the access terminal (110) establishes a connection with the first radio network (120) and receives the data.
