Abstract
A method in a communication system of transferring control of a user-plane entity from a first control-plane entity to a second control-plane entity is provided. The user-plane entity sends a set of identifying parameters to the first control-plane entity, which subsequently sends the set of identifying parameters to the second control-plane entity. The second control-plane entity determines if it can control the user-plane entity. If the second control-plane entity can control the user-plane entity, then the second control-plane entity sends an indication to the user-plane entity that a change in control-plane entities has occurred and that at least some resources of the user-plane entity that were controlled by the first control-plane entity are to be controlled by the second control-plane entity. The resources may be allocated to a mobile terminal and the change in control entity may be the result of a change in location of the mobile terminal.
