Abstract: A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each such PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant (i.e., whether the mobile station is engaged in a call).

Abstract: A method of wireless communicatIn some aspect restricted access nodes are assigned to a designated common channel while access terminals that are in active communication with a macro access node may selectively be assigned to the designated channel. In some aspect an access terminal associated with macro access node may perform a handoff to a different carrier when the access terminal is in the vicinity of a coverage area of a restricted access node. In some aspect an access terminal associated with a macro access node may perform a handoff to a different carrier based on location information. In some aspect access to a restricted access node is controlled based on policy and/or based on operation of an access terminal associated with the restricted access node.

Abstract: A method and system provides for efficient data throughput by avoiding unnecessary data sub-packets transmission while not missing new data packets. The method and system distinguishes between a sub-packet for a current data packet and a sub-packet for a new data packet by assigning different codes to them. When a currently received sub-packet and a previously received sub-packet for a previously decoded data packet have equivalent codes, the remote station ends (506) an acknowledgement signal to the base station, preventing unnecessary sub-packets transmission. When the currently received sub-packet and the previously received sub-packet have different codes, the remote station sends (510) an acknowledgement signal, if the remote station can decode the new packet from the current sub-packet. Otherwise, the remote station sends (516) a negative acknowledgement signal to the base station, and requests more sub-packs for the current packed if the limit on number of transmission for currently received sub-packet has not reached.

Abstract: Embodiments disclosed herein relate to providing dynamic assignment of home agent and home address in wireless communications, such that a mobile node away from home may receive local access services from a visited network. In an embodiment, a mobile node accesses a visited network. The visited network authenticates the mobile node with its home network. The visited network then assigns a visited home agent and a home address for the mobile node. The mobile node subsequently performs secure binding with the visitor home agent. The mobile node proceeds with communications using the visitor home agent and home address.

Abstract: In a channel structure for use in communication systems, two sets of physical channels, one for the forward link (50) and another for the reverse link (52), are utilized to facilitate communication of a variety of logical channels. The physical channels comprise data and control channels. In the exemplary embodiment, the data channels comprise fundamental channels which are used to transmit voice traffic, data traffic, high speed data, and other overhead information and supplemental channels which are used to transmit high speed data. The fundamental channels can be released when the remote stations are idle to more fully utilize the available capacity. The control channels are used to transmit paging and control messages and scheduling information.

Abstract: An apparatus and method for communications of scheduling information of reverse link transmissions are disclosed. A base station controller determines scheduling of a reverse link supplemental channel transmission for a mobile station in a communication system (100). The base station controller groups the mobile station in a group of mobile stations and assigns a forward link channel assignment channel to the group of mobile stations. A transceiver (400) incorporates information relating to the determined scheduling in the assigned forward link common assignment channel and transmits the assigned forward link common assignment channel to the mobile station for scheduling the reverse link supplemental channel transmission. The mobile station receives the assigned forward link common assignment channel. The mobile station schedules transmission of the reverse link supplemental channel transmission in accordance with the determined scheduling and transmits the reverse link supplemental channel in accordance with the determined scheduling.

Abstract: Method and apparatus for encrypting transmission traffic at separate protocol layers L1, L2, and L3 so that separate encryption elements can be assigned to separate types of transmission traffic, which allows the implementation of different levels of encryption according to service requirements. Encryption elements use variable value inputs, called crypto-syncs, along with semi-permanent encryption keys to protect from replay attacks from rogue mobile stations. Since crypto-sync values vary, a method for synchronizing crypto-syncs at the mobile station and base station is also presented.
