摘要： A visited access gateway provides an emergency communication service to a visiting mobile unit. The visiting mobile unit transfers a user registration to a home communication network, and the home communication network transfers a home internet protocol address to the visiting mobile unit. Upon receiving an emergency call request having the home internet protocol address from the visiting mobile unit, the access gateway transfers the emergency call request having the home internet protocol address over a signaling tunnel from the visiting mobile unit to a visited call processing system, receives routing instructions from the visited call processing system, and exchanges emergency communications having the home internet protocol address over a bearer tunnel between the visiting mobile unit and a visited emergency service node.

摘要： A method, system, and computer-readable media are provided for maintaining optimized communication after a mobile device transitions to a new foreign agent during a communication session. When a mobile device moves to and registers with a new foreign agent within a communication session, the mobile device's home agent multicasts a message to all foreign agents within an optimization cluster informing them of the updated registration. Accordingly, the foreign agents within the optimization cluster can proceed to transmit data packets directly to the new foreign agent servicing the mobile device within the communication session.

摘要： A mobile node that is in communication with a correspondent node via a home agent initiates a process for establishing a route optimized mode of communication between the mobile node and the correspondent node. The mobile node sends a first initiating message to the home agent for delivery to the correspondent node and sends a second initiating message directly to the correspondent node. The mobile node secures the first initiating message by including an initiating-message authentication code that can be validated by the home agent or by an authentication server. The correspondent node responds by sending a first responsive message to the home agent for delivery to the mobile node and by sending a second responsive message directly to the mobile node. The home agent secures the first responsive message by adding a responsive-message authentication code that can be validated by the mobile node.

摘要： A mobile node using Mobile IP is served by a network access server (NAS), wherein the NAS has allocated a care-of address for the mobile node and a home agent has a mobility binding that associates the care-of address with the mobile node's home address. When the mobile node's care-of address is no longer valid, an intermediary server receives a notification messages from a first network element (e.g., the NAS or home agent) and sends a resource management message to a second network element (e.g., the home agent or NAS). In response to the resource management message, the second network element clears at least one resource associated with the mobile node. For example, the NAS may de-allocate the care-of address and the home agent may clear the mobility binding.

摘要： Wireless networks comprise base stations that each have communication ports. The wireless networks exchange media with user devices through the communication ports. The wireless networks are identified by Ethernet OUIs, and the base stations and ports are identified by unique codes. An Ethernet backhaul network exchanges the media in Ethernet frames between the communication ports. The Ethernet backhaul network routes the Ethernet frames based on MAC addresses that indicate a destination OUI, a destination base station code, a destination port code, a source OUI, a source base station code, and a source port code.

摘要： Methods are described for managing the allocation of IPv6 addresses to mobile devices. More specifically, the network portions of IPv6 addresses are dynamically allocated to mobile devices by a home agent. In one embodiment, a request is received to allocate a network portion of an IPv6 address. It is determined whether a network portion is stored in a database in association with the mobile device. If so, that network portion is allocated to the mobile device so that the mobile device can establish a communication session. If not, the home agent is asked to allocate a network portion that is currently available.

摘要： Methods are provided for negotiating a static IPv6 address with a mobile device such that the mobile device can use the address to establish a communications session. Initially, a static IPv6 address that the mobile device is proposing to use is received. It is determined that the static IPv6 address is stored in a database in association with the mobile device. As the static IPv6 address is stored, the mobile device is allowed to establish a communications session using the proposed IPv6 address.

摘要： Methods are described for communicating a reregistration timer to a mobile device. A request is received from a mobile device to establish an IP communication session so that the mobile device is able to communicate by way of a wireless communication network. An allocation component assigns an IP address to the mobile device, in addition to a lifetime value that indicates a length of time after which the IP communication session expires. A threshold value is determined, which is a length of time prior to the expiration of the IP communication session when the session is to be renewed to avoid expiration. Based on the lifetime value and the threshold value, an existing lifetime timer is set and communicated to the mobile device, along with the assigned IP address.
