Abstract

A method and corresponding equipment by which a mobile station (wireless terminal) is able to undergo handover to another cell of a telecommunication system, and continue to receive a point-to-multicast transmission (e.g. MBMS packets) without a delay otherwise caused because of having to receive a channel (e.g. PBCCH in case of MBMS) conveying system information in the new cell and so causing the mobile station to first obtain the bearer information/location for the system information channel. The method is based on the mobile station using information in a neighboring cell information message (e.g. the MNCI message in case of an MBMS session) or other message (possibly specially defined) before changing to the new cell to determine the bearer information for the system information channel in the new cell (and also obtaining from the neighboring cell information the bearer information for receiving the point-to-multipoint transmission in the new cell).
