Configuration of HS-DSCH serving cell change improvements

摘要

The present solution relates to a method in a user equipment for configuring a cell change procedure to be used for handover in a wireless communication network. The user equipment is situated in a serving cell and comprises an active set of cells. The active set of cells comprises a list of cells to which the user equipment can move from the serving cell. The user equipment sends a request to a network controller comprised in the wireless communication network to add at least one further cell to the active set. The user equipment then receives the requested active set update from the network controller. The received active set update comprises the at least one further cell to be added to the active set and a list of cells to which a modified cell change procedure shall be used for handover. A neighbor cell which is stronger than a current serving cell is detected. This detected stronger neighbor cell is matching with the received list of modified cell change procedure cells, and the modified cell change procedure for the handover to the stronger neighbor cell is applied if the stronger neighbor cell is found matching a cell on the list.

主权项

1. A method in a user equipment for configuring a type of cell change procedure to be used for cell change in a wireless communication network, the method comprising:
receiving information that configures use of a modified cell change procedure by the user equipment on a cell level; determining to change from a serving cell to a particular target cell; and applying either the modified cell change procedure or a regular cell change procedure for the change based on whether the received information configures the user equipment to use the modified cell change procedure for changes to the particular target cell, wherein the modified cell change procedure and the regular cell change procedure differ in how a cell change command is transmitted to the user equipment.
