Abstract:
PROBLEM TO BE SOLVED: To provide an improved method for deploying small-coverage base stations.SOLUTION: An access point is configured based on acquired information. The access point may be configured based on configuration(s) of at least one other access point. An identifier to be transmitted by the access point may be selected based on identifier(s) transmitted by the 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 the configuration server and the configuration server may respond with a list of neighboring access points for that access point. The configuration server may provide configuration information to an access point on the basis of the location of the access point. The configuration server also may direct an access point to a different configuration server.

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 provide a method of reporting and resolving conflicting use of a node identifier.SOLUTION: A wireless node receives wireless signals and determines, on the basis of those signals, that more than one node use the same node identifier. The wireless node may then report the conflicting use to a network node. An access point that discovers a conflicting use may report the conflicting use and/or select to use a different node identifier. Upon identification of a conflicting use, an access point negotiates with another access point to cause one of these access points to use a different node identifier. In some aspects, upon identification of a conflicting use, an access point delays for a period of time before determining whether a different node identifier is to be used at one of the nodes.
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.
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 provide a method of managing a set of wireless relay nodes to facilitate inter-node routing of packets.SOLUTION: 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, and 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 then defines a forwarding table on the basis of the routing table.
Abstract:
PROBLEM TO BE SOLVED: To enable an access terminal connected to a network to access a local IP network server that is in the same domain as a femto access point even when the access terminal is not connected over-the-air with a femto access point.SOLUTION: A first protocol tunnel is established between a security gateway 112 and a femto access point 106. A second protocol tunnel is then established between an access terminal 102 and the security gateway 112. In other implementations, the second protocol tunnel is established between the access terminal 102 and the femto access point 106, thereby routing a portion of the tunnel through the first tunnel.
Abstract:
PROBLEM TO BE SOLVED: To provide a method of deploying multiple protocol tunnels (e.g., IPsec tunnels) to enable an access terminal connected to a network to access a local network associated with a femto access point.SOLUTION: A first protocol tunnel is established between a security gateway and the femto access point. A second protocol tunnel is then established in either of two ways. In some implementations the second protocol tunnel is established between the access terminal and the security gateway. In other implementations the second protocol tunnel is established between the access terminal and the femto access point, and thereby a portion of the tunnel is routed through the first tunnel.
