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： First, a sending station (7) transmits to a registration station (6) a registration request including a telecommunications address such as a URL or telephone number for later use; the registration station (6) allocates a security code to the address, stores a database entry containing the address and security code and sends the security code to the sending station (7). When the sending station (7) wishes to send a message that includes the telecommunications address, it also includes the security code. A station (2) receiving the message sends a verification request containing the telecommunications address and the security code to a verification station (6) which determines whether there is a database entry that matches the telecommunication address and security code and if so, sends a clearance notification to the receiving station (2). The receiving station may prohibit, or at least warn against, communication with the address until such time at clearance is received.
