Abstract:
A method and user equipment for performing a handover between a MBSFN and non-MBSFN areas in a communication network is provided. The communication network comprises a first cell constituting a MBSFN area, a second cell constituting the non-MBSFN area, and a reserved cell between the first and second cells and subordinate to the MBSFN area. Reserved cell indication information being broadcast in the reserved cell. The method including: receiving the reserved cell indication information to learn that a user equipment is located in the reserved cell; measuring in the reserved cell, for a preset service, a first signal strength based on MBMS transmission and a second signal strength based on a single-cell transmission; and selecting the first or second cells as a target cell during a period in which a difference between the first and second signal strengths is lower than a preset threshold.
