    Abstract: Embodiments described herein relate to connected-state radio session transfer in wireless communications. A source access network controller may lock a source radio session associated with an access terminal (e.g., in response to detecting a handoff condition associated with the access terminal), where the source access network controller may be in communication with a data network. The source access network controller may also instruct a target access network controller to create a target radio session corresponding with the source radio session, and to establish a communication route between the data network and the access network via the target ANC. The source access network controller may then freeze a state associated with the source radio session and transmits the frozen state to the target access network controller.; The target access network controller may subsequently unfreeze the received state and further unlock the radio session, hence resuming control of the access terminal.

    Abstract: The present invention is a novel and improved method and system that prevents RLP3E from generating unnecessary NAKs, thus preventing unnecessary data frame retransmissions. The present invention is efficient, neither delaying the delivery of data frames to the higher data services layer nor delaying the delivery of necessary NAKs to the multiplex sublayer. Additionally, the present invention can be implemented with minimal changes to an existing RLP3E implementation. The present invention is applicable to systems such as cdma2000, W-CDMA, and EDGE, wherein data is transferred using an ARQ (automatic request for retransmission) mechanism, and wherein data packets are sometimes received in an order different from that in which they were transmitted.

    Abstract: Las modalidades descritas en la presente se refieren a metodos y sistemas para agrupar las senales piloto y utilizar tal agrupamiento para reportes sobre la resistencia de la senal piloto y administracion de conjuntos en sistemas de comunicaciones de multiportadora. En una modalidad, una red de acceso puede asignar un identificador de grupo (o "ID de grupo") a cada una de las senales piloto asociadas con el sector, por ejemplo, con base en las areas de cobertura de las senales piloto, y transmitir las senales piloto con las IDs de grupo correspondientes. La variacion de PN puede utilizarse como la ID de grupo. Una terminal de acceso puede agrupar las senales de piloto recibidas en uno o mas grupos de piloto de acuerdo con sus IDs de grupo, y seleccionar senales piloto representativas provenientes de cada grupo de piloto para reportes de la resistencia de piloto. La terminal de acceso tambien puede utilizar el agrupamiento de senales piloto para realizar una administracion eficaz de conjuntos.

    Abstract: Embodiments disclosed herein relate to methods and systems for grouping pilot signals and using such grouping for pilot strength reporting and set management in multi-carrier communication systems. In one embodiment, an access network may assign a group identifier (or'group ID') to each of the pilot signals associated with the sector, e.g., based on the coverage areas of the pilot signals, and transmit the pilot signals with the corresponding group IDs. PN offset may be used as the group ID. An access terminal may group the pilot signals received into one or more pilot groups in accordance with their group IDs, and select a representative pilot signals from each pilot group for pilot strength reporting. The access terminal may also use the pilot grouping to perform effective set management.

    Abstract: A method for delivering SMS to ATs in a first communication network providing DO and 1x interfaces and for offloading the delivery of the SMS from a second communication network including an MSC, comprising monitoring a DO control channel for pages by an AT and delivering the SMS in SIP to the AT over the DO interface. The method may further comprise tuning the AT to the DO interface and determining whether the AT is SIP registered for using the DO interface. An application server determines whether the AT is SIP registered for using the DO interface. When the DO interface is not available, the SMS may be delivered over the 1x interface and the method further comprises the AT sending a special SMS to an SMS gateway, which causes the application server to remember that the AT is now monitoring the first communication network including a circuit-switched network.

    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 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: Access terminal identification management providing a minimum distance between subnets before reusing subnet identifiers. Mobility criteria evaluation determines when to reassign an access terminal identifier. In one embodiment, the mobility criteria is whether any member of the active set for the access terminal belongs to an originating subnet. In an alternate embodiment, the criteria is whether the access terminal has traveled more than a minimum distance from the originating subnet. When a mobility criteria is violated, the access network assigns a new identifier. In one embodiment, the access terminal identifier is a long code mask based on a subnet identifier. Identifier management applies when crossing sector boundaries in a cellular system, and serves to reduce the ambiguity of mapping CC values to full UATI values, and to avoid overlapping assignments.
