Abstract: A system is proposed to provide handover in a mobile telecommunications environment, particularly applicable to 3GPP networks, which does not increase signalling overhead but minimises user data loss during handover. In the modified system, PDCP SDUs with Sequence numbers are buffered and retransmitted as necessary. At the time of handover, SDUs not received by the user device are forwarded to the target base station for forward transmission to the UE. The handover procedure is designed to minimise packet loss whilst keeping to a minimum the duplication of packet transmission over the air interface.

Abstract: A method of determining whether to accept a connection request from a user device requesting connection to a communications network is described. The method includes receiving a connection request from the user device, the connection request including a predefined identifier. A message requesting capability information associated with the user device is then generated and transmitted and the capability information is received in response. The method further includes determining whether to permit a connection to the user device based on the capability information and transmitting a message to release or reject or to establish the connection based on the determining. Apparatus for performing the method, including an eNodeB, gateway and user device are also described and corresponding methods of operation these components are provided.
