    摘要: Packet filtering is performed to detect for and discard malformed data packets that would be discarded by a wireless network if received from a wireless device. A cdma2000 network may restart a PPP session upon receiving (1) malformed data packets with source IPv4 addresses different from IPv4 addresses (if any) assigned to the wireless device or (2) malformed data packets with source IPv6 addresses having prefixes different from prefixes (if any) associated with the PPP session. The wireless device may receive data packets from a terminal equipment coupled to the wireless device and/or applications running at the wireless device. The wireless device may filter these data packets with packet filters to detect for malformed data packets with invalid IPv4 addresses, invalid IPv6 address prefixes, and so on. The wireless device discards malformed data packets and sends the remaining data packets to the wireless network.

    摘要: A method for generating privacy IP address includes pregenerating a first privacy address and generating a second privacy address when the first privacy address is allocated to an application. Addresses may be shared by applications or unique to a single application. A deprecation timer is started when an application binds to an allocated privacy address, now when the privacy address is generated. To minimize traffic flow disruptions a deprecated address is not deleted while the address remains in use. By pregenerating privacy addresses, an address can be promptly allocated to an application with out delays incurred by confirming that a new address is not a duplicate on the system. The method can be implicated on any device using privacy addresses, including mobile handset devices.

    摘要: A method and system that provides for efficient re-synchronization of a PPP link on a Um interface is provided. When the PPP link is connected, if an indication that the communications of the mobile station is associated with a new network server is detected, only the Um interface will undergo PPP configuration renegotiation. The method and system does not require the examination of all data packets for determining whether PPP configuration renegotiation is required.

    摘要: A system and method for transparent Mobile IP registration within PPP negotiation uses a mobile telephone to relay messages between terminal equipment and a Foreign Agent (FA). An IPCP configuration request message by the terminal equipment requesting the assignment of an IP address is modified by the mobile telephone to delete the IP address request option. Other configuration options are forwarded unchanged by the mobile telephone to the peer/network. The peer/network responds with an acknowledgement of the requested configuration options and flow control between the terminal and the MT is asserted to permit Mobile IP registration. In the course of Mobile IP registration, and IP address is assigned to the mobile unit by the FA. Upon completion of the Mobile IP registration, flow control between the mobile telephone and the terminal is deasserted and the IP address assigned during Mobile IP registration is provided to the terminal equipment. In addition, the previously requested options may also be acknowledged.

    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.

    摘要: A majority of the IP packets sent from an IP network over a wireless network to a mobile station which is tethered to an electronic device, such as a laptop computer, are destined for applications running on the electronic device. The embodiments are for snooping and filtering incoming IP packets to delineate only those packets destined for mobile station applications, which greatly improves the processing efficiency of the mobile station. In particular, the CID fields of TCP/IP packets utilizing Van Jacobson compression techniques are snooped and filtered.

    摘要: An ordered list of precedence values includes a number of blocks of precedence values. An operating system receives filters from an application. The operating system assigns a precedence value to each filter from the available block of precedence values that has the highest priority. Precedence values are assigned to maintain a precedence order specified by the application. Filters and their assigned precedence values are communicated to an entity that filters packets by applying the filters in the order of their precedence values. Filters for an application can be added, deleted, or modified without affecting the precedence values of other filters for other applications. If an assignment is to be made when the lowest priority block is not available, then a repacking operation is performed to fill unused blocks in the list. The repacking is performed to reduce signaling associated with communicating reassigned precedences values to the filtering entity.

    摘要: A method of supporting multiple PPP instances between a single wireless device and a wireless network using a single IP address and IP stack allows applications to exercise different link characteristics for individual PPP sessions. Routing based on parameters other than IP address, such as QOS parameters, that allow applications to utilize different types of services for same client server endpairs is provided. A PDSN determines whether or not multiple PPP sessions terminate at the same endpoint within a mobile device. A mobile device initiates a subsequent multiple PPP connection by specifying the IP address of an initial connection in the IP Address Configuration Option during IPCP negotiation for the subsequent connection. This address may be obtained from the IPCP phase of the initial PPP connection negotiation using Simple IP, or a Mobile IP Home Address obtained from the Mobile IP registration during establishment of the initial PPP session.
