In a communication network (), wireless access points () utilize one or more agents () to support the operating needs of corresponding mobile stations. Pursuant to one approach, the agent supports translation of the mobile station's end-to-end protocol-based messages to Internet Protocol-based messages that are readily ported through an Internet Protocol-friendly communication system infrastructure that preferably eschews the use of network elements that rely upon unique and/or proprietary non-Internet Protocol interfaces. Pursuant to another approach the wireless access point is able to interact on a peer-to-peer basis with other wireless access points in order to facilitate, for example, handovers and other mobility management tasks.

Method and apparatus to facilitate mobile station communications using internet protocol-based communications

A wireless access point () detects an indicia of a change in wireless connectivity of a mobile station () with respect to itself and another wireless access point (). The wireless access point then automatically effects at least one of establishing a communication between itself and the second wireless access point regarding the change in wireless connectivity and/or establishing a temporary data tunnel as between itself and the second wireless access point. These network elements can also act to automatically establish a data flow path for the mobile station as between the second wireless access point and a network element (such as a mobility management agent ()) that is external to the common subnet. In a preferred approach this comprises, at least in part, automatically sending a registration request to the network element other than in response to a specific request from the mobile station to send such a registration request.

Method and apparatus for reducing latency during wireless connectivity changes

A wireless access point (A,B,C) provides () a surrogate Internet Protocol address to use on behalf of a mobile station (). That wireless access point then uses () that surrogate Internet Protocol address along with its own Internet Protocol address to facilitate establishing one or more data tunnels as necessary to support the communication needs of the mobile station.

Method and apparatus for facilitate communications using surrogate and care-of-internet protocol addresses

Mobile station information is exchanged between a plurality of distributed mobility agents (). The exchange is initiated by a mobility agent () associated with a last known network access point () that has communicated with the mobile station (). The mobile station () is paged from at least one network access point using an available air interface technology to interface with the mobile station () and using the mobile station information. No centralized controller is used in the paging.

System and method for paging and locating update in a network

An indication is received from the mobile station () indicating that the mobile station () is moving from an originating mobility agent () to a destination mobility agent (). An identity of the destination mobility agent () is determined using the indication. Routing information is sent from the originating mobility agent () to the destination mobility agent () using the identity. Incoming data is routed to the mobile station () using the routing information.

System and method for providing a distributed virtual mobility agent

A wireless access point (), upon determining () that a need exists to support a communication need of a mobile station, acquires () a first Internet Protocol (IP) address and automatically transmits () a gratuitous Address Resolution Protocol message to a local router to thereby cause the latter to correlate the first IP address to a Medium Access Control address for the wireless access point. In a preferred embodiment the wireless access point can also automatically transmit a registration request to a remote network element (such as a Home Agent) that presents this first IP address as a care-of address to use in conjunction with another IP address that serves as a home address for the mobile station.
