Abstract:
In the present technique of a communication system (100), an address of a forwarding agent (114) linked to a receiver node (112) is detected to provide a discovered address. The discovered address is then used to establish a direct route with the forwarding agent of the receiver node for subsequent communications between a sender node (104) and the receiver node.
Abstract:
A method for prioritizing Mobile IP between PMIP and CMIP includes the steps of connecting a mobile device (118) to a communication network (102) and determining (308) if the network provides mobility control, such as the network being PMIP-enabled. When it is determined that the network provide mobility control, the mobility function is assigned (312) to the network and is therefore given priority over the mobility function provided by the mobile device. It can be determined (304) that the mobile station also includes a mobility control so that when the network is not PMIP-enabled the mobile station controls (314) layer 3 mobility and the Mobile IP function.
Abstract:
An indication is received from the mobile station (114) indicating that the mobile station (114) is moving from an originating mobility agent (106) to a destination mobility agent (108). An identity of the destination mobility agent (108) is determined using the indication. Routing information is sent from the originating mobility agent (106) to the destination mobility agent (108) using the identity. Incoming data is routed to the mobile station (114) using the routing information.
Abstract:
Mobile station information is exchanged between a plurality of distributed mobility agents (106, 108). The exchange is initiated by a mobility agent (106) associated with a last known network access point (110) that has communicated with the mobile station (114). The mobile station (114) is paged from at least one network access point using an available air interface technology to interface with the mobile station (114) and using the mobile station information. No centralized controller is used in the paging.
Abstract:
A wireless access point (102) detects an indicia of a change in wireless connectivity of a mobile station (101) with respect to itself and another wireless access point (103). 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 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 between the second wireless access point and a network element (such as a mobility management agent (105)) 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.
Abstract:
A wireless access point (200), upon determining (101) that a need exists to support a communication need of a mobile station, acquires (102) a first Internet Protocol (IP) address and automatically transmits (103) 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.
