    Abstract: An access point is configured based on acquired information. An access point may be configured based on the configuration(s) of at least one other access point. An identifier to be transmitted by an access point may be selected based on the identifier(s) transmitted by at least one other access point. An access point may configure itself with assistance from a configuration server. For example, the access point may send information such as the location of the access point to a configuration server and the configuration server may respond with a list of neighboring access points for that access point. A configuration server may provide configuration information to an access point based on the location of the access point. A configuration server also may direct an access point to a different configuration server.

    Abstract: Seamless communication handoff is achieved by establishing a protocol tun nel to route leftover packets between network access nodes during the handof f. For example, in a mobile IP-based system, a mobile node may perform a han doff from a first access node that is associated with a first routing node t o a second access node that is associated with a second routing node. To pre vent the loss of any packets that may be in route for delivery to or from th e first routing node during the handoff, the mobile node establishes a proto col tunnel with the first access node via the second access node. On the for ward-link, packets being delivered from the first routing node are routed ov er the protocol tunnel to the second access node and then to the mobile node . On the reverse-link, packets being sent to the first routing node are rout ed over the protocol tunnel from the mobile node to the second access node a nd then to the first routing node. In conjunction with these operations, the mobile node concurrently maintains separate IP interfaces for the routing n odes. In addition, steps are taken to ensure that packets are routed to the appropriate IP interface during the handoff.

    Abstract: An automated neighbor discovery by a base station with the assistance of an access terminal are disclosed. An exemplary method includes receiving a first message from an access terminal based on detecting an identification signal by the access terminal from the first base station in a communication system. Determination whether the first base station is a known base station is then made. If the first base station is not known, a second message is transmitted to the access terminal requesting a network identification of the first base station. A third message from the access terminal is received in response to the second message including the requested network identification. A request for identification data is sent by the second base station to the first base station via a network link based on the network identification. Corresponding apparatus and other exemplary methods are also disclosed.

    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.

    Abstract: In a communication system in which a mobile station accessing 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 has stored 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: Described herein is methodologies for efficient utilization of backhaul r esources of a network for delivering paging data to an access terminal (AT) without sacrificing delay performance. A location that buffers data for an A T can be adaptively changed based on factors such as the location of the AT, applications utilized by the AT, and a recent activity level of the AT. To facilitate this determination, an AT can be configured with one or more regi stration boundaries. An AT can be configured with a small registration radiu s such that if the AT does not move outside of the small registration radius , data can be delivered directly to a data attachment point for the AT. If t he AT moves outside of the small registration radius, the registration radiu s can be switched to a large registration radius and the access gateway can instead locally buffer data for the AT.
