PROBLEM TO BE SOLVED: To provide a system, an apparatus and a method for scheduling users on a bandwidth smaller than the entire bandwidth, in order to support mobile stations that cannot demodulate the entire bandwidth or that can demodulate a bandwidth smaller than the entire bandwidth.SOLUTION: A processor is configured to: receive a plurality of communications from each of a plurality of wireless access terminals; in response to the communications, make respective related determinations whether the respective related wireless access terminals are simultaneously operable on one or more carriers; on the basis of the determinations, assign at least one carrier to each of the wireless access terminals; and, on each of the plurality of assigned carriers, instruct a plurality of control channel transmissions.

PROBLEM TO BE SOLVED: To achieve efficient utilization of communication resources by appropriate handoff of a data attachment point associated with the handoff of an access terminal.SOLUTION: In a communication system, a gateway entity 32 is linked to a plurality of infrastructure entities 34 and 36 and an access terminal 44 establishes a data attachment point (DAP) with one of the infrastructure entities 34 and 36 to communicate with it. The access terminal 44 determines to initiate the handoff of the DAP associated with the handoff of the access terminal 44 between infrastructure entities 34 and 36 by weighing factors such as the link conditions with the various infrastructure entities, the time since the last DAP handoff, and time duration communicating with the current infrastructure entity before proceeding with the DAP handoff.
Abstract:
PROBLEM TO BE SOLVED: To improve efficiency in establishing or updating data attachment points (DAPs) in a wireless access network (AN).SOLUTION: An algorithm identifies access points (APs) of a particular wireless AN and further identifies one or more access gateways (AGWs) to a data network. A cost metric for a plurality of the APs is determined to at least one AGW. The plurality of APs comprises at least a serving AP for an access terminal (AT) and a current or default data AP. An AGW that provides a lowest cost metric for the serving AP is determined. The lowest cost metric is compared with a cost metric of the data AP, also with respect to such an AGW. If the cost metric of the serving AP is lower than the cost metric of the data AP, the serving AP is updated to act as the data AP for the AT.

PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate reducing battery consumption during periods of inactivity intermixed with traffic bursts in wireless communications systems.SOLUTION: A semi-connected mode is provided for fast recognition of mobile devices upon wakeup and access while enabling the mobile devices to operate in reduce power states. A mobile device operates in the semi-connected mode with all base stations in an active set of the mobile device. Moreover, mechanisms are provided to notify mobile devices of pending data while avoiding latency associated with paging channels.
Abstract:
PROBLEM TO BE SOLVED: To provide a method allowing free selection of each of a forward link and a reverse link having good communication conditions during a handoff process.SOLUTION: In a communication system in which a mobile station accesses the main network via a plurality of base stations, the mobile station can freely select any of the base stations as a forward link (FL) serving station. In addition, the mobile station can also freely select another or the same base station as a reverse link (RL) serving station. The mobile station stores in its memory a plurality of routes corresponding to the plurality of base stations, with each route dedicatedly assigned to a particular base station. During handoff of one base station to another as either the FL or the RL serving station, exchanged data packets are processed in the respective routes of the base stations involved.
Abstract:
PROBLEM TO BE SOLVED: To resolve resource assignment conflicts between access terminals in a wireless communication environment.SOLUTION: A first access terminal may receive a "sticky" assignment (a persistent resource assignment meaning allocation that has an unlimited duration) of a set of resources. In the event that a second access terminal requires a brief resource assignment, a time-limited, or "non-sticky" resource assignment may be granted to the second access terminal. If a resource in the non-sticky assignment has been already assigned to the first access terminal by the sticky assignment, the first access terminal may receive an indication of the conflict along with information related to a duration of the non-sticky assignment, may surrender the conflicted resource, and may resume control over the conflicted resource after the termination of the non-sticky assignment.
Abstract:
PROBLEM TO BE SOLVED: To provide a method for processing wireless signal components for a mobile wireless access broadband service, especially a method for processing inter-frequency handoff and inter radio access technology handoff.SOLUTION: The method includes processes for defining a protocol that controls whether to invoke a tune away component to determine an alternative wireless communications path. This includes defining one or more tune away parameters for the tune away component. Then, the alternative wireless communications path can be automatically selected based in part on the tune away procedure and at least one of the tune away parameters.
Abstract:
In order to mitigate the security risk posed by the insertion of a relay node (120, 404) within a communication network (100), both device authentication and subscriber authentication are performed on the relay node (120, 404}. Device and subscriber authentication may be bound together so that a relay node (120, 404) is granted access to operate within the network only if both device and subscriber authentication are successful. Additionally, a communication network (100) (or authentication node) may further verify that a subscriber identifier (received as part of subscriber authentication) is associated with the corresponding device type (identified by the device identifier in the corresponding device authentication) as part of the subscriber authentication process.

Abstract:
Systems and methods of generating quick paging messages having nearly unique identifiers and variable capacity are described. The system generates a quick paging message identifying an access terminal to indicate the presence of a scheduled paging message for that access terminal. The system generates a quick paging notification for each access terminal having a scheduled paging message and generates a compressed nearly unique identifier of each access terminal that is notified in the quick paging message. The compression technique can vary based on the number of bits allocated to the quick paging message as well as the number of access terminals notified in one quick paging message.
Abstract:
Methods and systems are described for verifying that advertising content has been downloaded by a client. When a streaming client requests advertising content from an advertising server, the streaming client receives one or more verifiers from the advertising server. The streaming client sends information associated with the verifiers to a media server. The media server is configured to validate streaming of the advertising content to the streaming client based on the information associated with the verifiers.
