Abstract
A method and apparatus for establishing a user plane between a user plane entity and different access nodes assigned to different pool areas simultaneously for multicast or broadcast service provision. The method includes receiving at a respective access node assigned to the different pool areas simultaneously plural session start messages indicating different user plane entities of the different pool areas, selecting by the respective access node one user plane entity out of the indicated user plane entities indicated in the session start messages based on a selection rule common to all access nodes assigned to the different pool areas simultaneously, the selection rule ensuring that the access nodes assigned to different pool areas simultaneously select the same user plane entity out of one of the different pool areas, and establishing by the access nodes a respective user plane to the same selected user plane entity.
