Abstract: Techniques for efficient storage and retrieval of Preferred Roaming Lists are disclosed. In one aspect, PRL entries are stored in two tables. One table contains records that are common to two or more PRL entries. Another table stores any information that is unique to a PRL entry, as well as an indicator of which common record is associated with it. The common record is concatenated with the unique information to generate the uncompressed PRL entry. Various other aspects of the invention are also presented. These aspects have the benefit of reducing the memory requirements for storing a PRL. In addition, time required to download the compressed PRL is reduced.

Abstract: This disclosure provides a method and apparatus for the communication of low delay data over multiple channels having different speed and latency and requiring a different amount of time to set up. In one embodiment, the transmitter removes duplicate data packets from a queue after a second channel, such as a dedicated channel is established. In an alternate embodiment, sequence numbers are assigned to data packets, allowing the receiver to identify duplicate packets and ignore the duplicates.

Abstract: For efficient communications of data across various protocol layers in a communication system (100), a base station (101) receives radio link protocol (RLP) packets (509) of data over a physical layer protocol (505). A processor (401) assembles received RLP packets (509) of data. The processor (401) is configured for determining whether a received RLP packet (509) of data is received out of sequence in a series of RLP packet (509) of data, starting an abort timer associated with a transmitted negative acknowledgment for measuring an elapsed time of the abort timer, determining whether the elapsed time of said abort timer exceeds an abort period of time dynamic threshold that is based on statistical data of periods of time measured for previously received successful retransmissions of RLP packet (509) of data.

Abstract: Methods and apparatus for authorizing an access terminal (AT) requesting a service provided by an entity in an access network are disclosed. After being authorized for a communication session with the access network, the AT addresses an inquiry to a domain name server (DNS) for a contact of a service selector (SS) administering the desired service. A controller in the access network (BSC/PCF) routs the inquiry to and returns a response from the DNS. The AT then addresses a service query containing the AT's capabilities to the SS. The BSC/PCF directs attributes allowing the SS to authorize the service. Upon the SS's acknowledgement of the attributes, the BSC/PCF forwards to the SS the service query. Upon authorization, the SS notifies the BSC/PCF, and if the AT is authorized, selects in accordance with the AT's capabilities an appropriate service provider (SP) to provide the service.

Abstract: Method and apparatus for variable length Physical Layer (PL) packet generation. Multiple Security Layer (SL) packets may be multiplexed into a single PL packet to increase efficiency, wherein the SL packets may have variable lengths. In one embodiment, different format SL packets for different users are combined into capsules that form the PL packet. Shorter packets are for users in poor channel conditions or requiring smaller amounts of data due to the applications and the accompanying Quality of Service (QoS) requirements. In one embodiment, a modified Preamble structure provides for Unicast or multi-user packets. Alternate embodiment provides modified Rate Sets, a mechanism for identifying ACK from a single-user packet or a multiplexed packet (delayed ACK). ON/OFF keying for ACK channel v/s bi-polar keying used in IS-856, and/or multi-valued interpretation of DRC.

Abstract: Techniques to determine whether or not a terminal is under the coverage of a current wireless communication system (e.g., a packet data system) and to switch from the current system to another wireless communication system (e.g., a voice/data system). In one method, at least one measurement of at least one parameter for at least one base station in the current system is initially obtained. The measurement(s) may be SNR measurements. A metric is derived based on the measurement(s) and used (typically along with a metric threshold and a timer) to determine whether or not the terminal is within the coverage of the current system. A switch to another system is initiated if the terminal is deemed to be outside the coverage of the current system. The two systems provide at least one common service (e.g., packet data service).

Abstract: Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve monitoring a first network in accordance with a first air interface, and receiving a message from a second network through the first air interface, the second network being associated with a second air interface different from the first air interface. Various registration and related techniques are also discussed for maintaining connectivity with both networks as the wireless communications device moves through different geographic coverage regions.

Abstract: Methods and apparatus for providing location information to an Access Terminal (AT) when the Access Network (AN) is unable to contact a last serving PDSN, else maintaining the previous location information. In one embodiment, AN elements within an area supported by a Packet Data Serving Node (PDSN) are given a same Access Network ID (ANID). In this way, movement of the AT within the area supported by the PDSN do not initiate an update of location information. The AT receives location information specific to the PDSN and not the AN.

Further, the flexibility of the micro-tunnels optimizes the resources of the system. On request for a data service, an encapsulation configuration record is generated. An encapsulation header is created in response to the encapsulation configuration. The encapsulation header includes a packet service identifier and a micro-tunnel identifier.

Abstract: A method and apparatus for generating an autonomous Pilot Strength Measurement Message (PSMM) by a mobile station traveling in a multi-carrier wireless communication system. In a multi-carrier system, the mobile station receives the pilot channel of a base station on multiple carrier frequencies simultaneously. Fading may vary from carrier frequency to carrier frequency. New pilot strength definitions are used by the mobile station in a set of rules transmitted by the base station. The set of rules determines autonomous generation and transmission of PSMMs by the mobile station upon detection of pilots.

Abstract: Assignment of a session information IP address for use as a mobile station identifier facilitates a distributed architecture for processing IP communications in coordination with a wireless communication system. The session information IP address identifies a storage location of session information for a given AT. The AT effectively carries a pointer to the session information, wherein an access point is able to access the session information directly. This avoids the need to store mapping information for each AT and associated location of session information. Additionally, use of an IP address identifying the session holder as a mobile station identifier avoid delays incurred by such mapping. The session information IP address may be compressed to use a locally unique value. The compressed version conserves bit space, and reduces processing complexity on relocation to a next access point.

Abstract: Techniques for aggregating multiple air interfaces to achieve higher data rates using standard link interfaces and a single user identifier are disclosed. In one aspect, each of a plurality of radio elements is associated with a unique link identifier and a common subscriber identifier. In another aspect, a base station authenticates a radio element by comparing a transmitted link identifier with a list of link identifiers accessed from a subscriber database indexed by subscriber identifier. In yet another aspect, a wireless connection is linked with an access node through an interface distinguished by the link identifier. The connection can be merged with other connections in a multi-link protocol. These aspects have benefits including allowing multiple devices to be supported with one subscriber identifier, achieving higher data rates due to aggregation of multiple links using standard interfaces, a single record per subscriber, and others.

Abstract: A cryptosync design comprising (1) a channel identifier indicative of a particular channel via which a data packet is sent, (2) an extended time stamp indicative of a time value associated with the data packet, and (3) a counter indicative of a packet count associated with the data packet. The lengths of the extended time stamp and counter fields and the time unit for the extended time stamp are parameters that may be configured for each channel. At the sender, the extended time stamp for the cryptosync may be obtained from the System Time maintained by the sender. The counter value for the cryptosync may be provided by a counter that is maintained for the channel by the sender. The sender may include a time stamp and/or the counter value, if they are needed to derive the cryptosync at the receiver, in a header of the data packet.

The mobile station receives the assigned forward link common assignment channel.

Abstract: A method, and corresponding apparatus, applies to individual base stations in a wireless communications systems, where each base station performs rate assignment to mobile stations optimally, but independently of the other base stations. Different base stations affect each other through other cell interference, and continuously modify their reversed link rate assignment based on the other-cell interference received and the requested rates from the mobile stations. The base stations converge to a stable condition with uncoordinated optimizations. The optimizing technique maximizes total through put in each cell (maximizing rates) while maintaining interference to other cells at a minimum level, and being subject to at least some of the following constraints: mobile station's maximum transmit power, mobile station's requested rate, discrete set of possible rates, maximum rise-over-thermal interference at the base station, and minimum required received error per bit normalized for noise.
