Method and apparatus for topology management for handovers in heterogeneous networks

摘要

A method comprises receiving a relocation required message for a user equipment from a source Radio Access Network (RAN); multicasting a relocation request to multiple local RANs; receiving a first relocation acknowledgement from a first local RAN of the multiple local RANs to which a user equipment may be handed into; and forwarding the first relocation acknowledgement to the source RAN.

1. A method, comprising:
receiving a first relocation request message corresponding to a user equipment in a source Radio Access Network (RAN); in response to receiving the first relocation request message, multicasting a second relocation request message to multiple local RANs, the second relocation request message including parameters enabling the multiple local RANs to allocate resources such that a pre-configured relocation acknowledgement is received from any of the multiple local RANs in response to the second relocation request message; receiving a first pre-configured relocation acknowledgement from a first local RAN of the multiple local RANs to which a user equipment may be handed into; and forwarding the first pre-configured relocation acknowledgement toward the source RAN.
