H04W 4/00

US Classification:

370329

Abstract:

In a communication system in which a gateway entity is linked to a plurality of infrastructure entities which in turn are operable to communicate with an access terminal, the access terminal needs first to establish a data attachment point (DAP) with one of the infrastructure entities. Handoff of the DAP from one infrastructure entity to another infrastructure entity is initiated by the access terminal. The access terminal weighs 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:

Disclosed is a method for multiple EAP-based authentications in a wireless communication system. In the method, a first master session key (MSK) is generated in a first EAP-based authentication for a first-type access. A first temporal session key (TSK) is generated from the first master session key (MSK). A second EAP-based authentication is performed, using the first temporal session key (TSK), for a second-type access. First-type access and second-type access are provided after the first and second EAP-based authentications are successfully completed.

US Classification:

455405, 455445

Abstract:

In a converged communication network, IP data packet services are provided by a core network to access terminals via radio access nodes (RAN). By positioning accounting report triggering closer to the usage, accuracy and comprehensive of accounting is achieved, which can also reduce overhead burdens on the core network. Additional responsibility is given to an access gateway (AGW) between an enhanced base station (eBS) of the RAN and the core network that can reduce the volume and increase the accuracy of accounting message traffic to an authentication, authorization and accounting (AAA) server of the core network. The AGW informs the eBS of accounting rules to be used in making air link records that are merged and formatted in accordance with an accounting protocol for sending to the AAA server, to address duration and volume based accounting needs, postpaid and prepaid accounting types, and user, service and flow based accounting categories.

US Classification:

370252, 370255, 455525

Abstract:

An algorithm for improving efficiency of data attachment points (DAPs) in a wireless access network (AN) is provided herein. By way of example, the algorithm can identify a serving access point (APs) coupling an access terminal (AT) to the wireless AN. A cost metric for the serving AP can be determined with respect to at least one data network access gateway (AGW) of the wireless AN. The cost metric can be compared with a similar cost metric of a current or default DAP assigned to the AT. If the cost metric of the serving AP is lower than the cost metric of the current/default DAP, the DAP can be re-assigned to the serving AP, minimizing wireless AN resource costs associated with the DAP.

US Classification:

370400, 230329, 230390, 230434

Abstract:

Local breakout is provided by one or more nodes (e. g. , a local access point and/or a local gateway) in a wireless network to facilitate access to one or more local services. In conjunction with local breakout, multiple IP points of presence relating to different levels of service may be provided for an access point. For example, one point of presence may relate to a local service while another point of presence may relate to a core network service. IP point of presence may be identified for an over-the-air packet to indicate a termination point for the packet. Also, different mobility management functionality may be provided at different nodes in a system whereby mobility management for a given node may be provided by a different node for different types of traffic. Thus, an access terminal may support multiple NAS instances. In addition, different types of paging may be provided for different types of traffic.

US Classification:

370331, 455436

Abstract:

Systems and methods for switching among networks (e. g. , heterogeneous) and inter-working between a source access system and a target access system, by implementing tunneling from the AT to the target access system via the source access system. An inter-system handoff control component can facilitate setting tunneling by the mobile unit to the target access and/or between the source access system and the target access system—wherein signaling/packeting associated with the target system can be transferred over the source system.

Abstract:

A set of wireless relay nodes are managed to facilitate inter-node routing of packets in the set. In some aspects, unique identifiers are defined for the wireless relay nodes to facilitate routing packets within the set. In some aspect a routing table is provided to each of the wireless relay nodes, wherein the routing table identifies each wireless relay node in the set and a next-hop entity for each of these wireless relay nodes. Each of the wireless relay nodes may then define a forwarding table based on the routing table.

Abstract:

Techniques for enhanced backhaul flow control are provided. In an exemplary embodiment, a backhaul control system is described that comprises a base station controller (BSC), a backhaul network, and a base transceiver station (BTS). Each is responsive to data and messaging transmitted and received. In one aspect, the BTS includes a queue and a controller. The amount of data in a queue is adjusted by a controller based upon calculating a target queue size value. The controller non-uniformly adjusts the amount of data in a queue based upon a target queue size value which is based upon communication system parameters. The target queue size and amount of data in a queue is adjusted so as to reduce buffer underrun, decrease system latency, and increase communication system throughput.
