摘要:
Using split interfaces for Internet Protocol version 6 (IPv6) and Internet Protocol version 4 (IPv4), and bridging the IPv4 interface, makes it possible to support a Tethered Device (TD) and an Access Terminal (AT) having concurrent IP connectivity. This configuration enables the support of IP Multimedia Subsystem (IMS) applications in the AT using IPv6 while concurrently supporting general Internet usage on a TD. It is also possible to bridge an IPv6 interface to the TD.

This disclosure is directed to techniques for selection of wireless network interfaces for data communication within an access terminal. The techniques may rely on a set of interface selection rules to identify network interfaces that are eligible to serve a particular communication application or the type of traffic forwarded on behalf of another device. In addition, each network interface may be assigned a priority. Upon identifying eligible interfaces, e.g., interfaces that satisfy all of the interface selection rules, the techniques may involve selection of the eligible interface having the highest priority. The assigned priority may be dynamically adjusted based on the connection state of the interfaces, prioritization according to changes in system latency, interface cost, and the like.
摘要:
To initiate dormancy early, a wireless device receives an IP packet from a wireless network and determines whether the received IP packet is an unsolicited IP packet. An unsolicited IP packet may be declared if the received IP packet causes the wireless device to reactivate from dormancy or is not delivered to an application or service running at the wireless device. The wireless device transitions to dormancy early if the received IP packet is deemed to be an unsolicited IP packet and no other events prevent transition to dormancy. The wireless device may use (1) a shortened value for an inactivity timer for a predetermined time duration if an unsolicited IP packet is detected and (2) a nominal value for the inactivity timer thereafter. The wireless device resets the inactivity timer whenever an IP packet is sent or received and transitions to dormancy upon expiration of the inactivity timer.
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:
A system for efficiently accommodating an authentication protocol in a communications system. The system includes a first mechanism for establishing a first communications interface between a first device and a second device and for establishing a second communications interface between the second device and a third device. A second mechanism selectively relays authentication signals received by the second device between the first device and the third device. A third mechanism employs the third device and the second mechanism to authenticate the first device via the first communications link and the second communications link.
摘要:
A method and a wireless communication device capable of flow controlling data to be sent from a TE2 device over a Rm interface when PPP renegotiation occurs over a Um interface. Flow control is asserted by the MT2 device by means of manipulating electrical signaling of a physical interface between the MT2 device and the TE2 device. A second embodiment provides a method and a wireless communication device for buffering data on the MT2 device when the PPP renegotiation of the Um interface occurs. In a third embodiment, data is buffered when the PPP renegotiation of the Um interface occurs. When an amount of free buffer space is less that a predetermined threshold, flow control is asserted to the TE2 device.
摘要:
A wireless communication device (100) includes a manual input device (120, 122), a key lock memory (108), and a key lock processor (104). The processor (104) accesses user-programmable parameters stored in the memory (108) that define conditions for automatically disabling and also enabling commands to be issued from the manual input device (120, 122). When the processor (104) determines that the disabling condition has been met, the manual input device (120, 122) is automatically disabled, and will remain disabled until the enabling condition is met. The wireless communication device (100) may further include a timer (130) to measure elapsed time, and a display (124) to show a label indicating the status of the manual input device (120, 122). The manual input device (120, 122) of the wireless communication device (100) may be either, or both, a conventional keypad (120) or a dual-function rotatable switch (122).
摘要:
A method and a wireless communication device (MT2) for simultaneously negotiating LCP or IPCP configuration options over both the Rm and the Um interfaces. When the MT2 device receives either an LCP or an IPCP Configure-Request packet over one of the Rm or the Um interfaces, the MT2 device parses the requested configuration options and determines whether the requested options are supported by the MT2 device. If the requested options are supported, the MT2 device saves a Configure-Request ID, included in the Configure-Request packet, and frames the Configure-Request packet in a PPP frame for transmission on the other of the Rm or the Um interfaces. If any of the requested configuration options are not supported by the MT2 device, the MT2 device creates a Configure-Reject packet, including the unsupported options, and frames the Configure-Reject packet in a PPP frame for transmission over the interface through which it received the Configure-Request packet.
