Abstract
The present invention relates to transmitting information regarding a point-to-multipoint service a mobile terminal has joined a target radio network controller (TRNC) during SRNS Relocation. A serving radio network controller (SRNC) initiates the relocation by transmitting a first message for requiring the relocation, wherein the first message includes a message container comprising the information regarding the point-to-multipoint service the mobile terminal has joined. A core network (CN) receives the first message and transmits a relocation request to the TRNC, wherein the relocation request includes the message container. The TRNC transmits a relocation request acknowledgment to the CN to confirm or reject the relocation. The CN sends a relocation command to the SRNC to trigger the relocation. A relocation trigger is then transmitted to the mobile terminal for triggering the relocation and a relocation acknowledgment is received in the TRNC from the mobile terminal.
