Delivery of handover command

摘要

A delta configuration is transmitted to a UE requesting a handover wherein the delta configuration details changes that are required for the current UE configuration in order to execute the handover. The handover is initiated via a measurement report transmitted to a currently serving source eNode B from the UE. The measurement report can comprise one or more of current radio conditions, current UE configuration or a preferred target eNode B if the handover is a inter eNode B handover. In a inter eNB handover, the current UE configuration is forwarded to the preferred target eNode B by the source eNode B. The target eNode B generates the delta configuration and transmits it to the source eNode B in a transparent container which is subsequently forwarded to the UE.

1. A method comprising:
receiving at a target enhanced node B (eNB) a request for a handover comprising information regarding a current configuration associated with a UE requesting the handover, the current configuration associated with a source eNB serving the UE; identifying a new configuration for the UE associated with the target eNB; comparing the current configuration to the new configuration to identify differences between the current configuration and the new configuration; generating a delta configuration based on the comparison including one or more changes to the current configuration to facilitate the handover; and transmitting the delta configuration in a transparent container to the source eNB.
