摘要： A method of handling a data stream during a handover in a communications network comprising a first user agent having a fixed address, a proxy server and a second user agent, said method comprising the steps of: mapping at the proxy server the fixed address with a dynamic network address allocated to the first user agent; sending a request by the first user agent to the second user agent for a data stream; generating by the second user agent in response to the request a plurality of messages each comprising part of the data stream requested and the fixed address of the first user agent, wherein the message is a session initiation protocol message, and sending the messages to the proxy server; receiving the messages at the proxy server and determining the mapped dynamic network address corresponding to the fixed address in the message, and forwarding the messages to the determined dynamic network address; and when the first user agent is allocated a new dynamic network address, replacing by the proxy server the mapped dynamic network address with the new dynamic network address and forwarding the received messages to the new dynamic network address.

摘要： A method of selecting a candidate network from a plurality of candidate networks available for a client device to handover to from a first network. The method determines if the client device is supporting one or more sessions over said first network, determines one or more session characteristics of one or more of said sessions, determines one or more criteria for a candidate network to support said one or more session characteristics, and processes candidate network session information retrieved from a data store, wherein the candidate network session information comprises session information reported dynamically by at least one other client device having a session in a candidate network. Which available candidate networks is suitable for handover by the client device is determined by comparing processed candidate network session information with said one or more criteria for a candidate network to support said one or more session characteristics.
