Handover in a wireless telecommunication network environment

摘要

An example method for handover in a wireless telecommunication network environment is provided and includes receiving a handover request from a first Evolved Universal Terrestrial Radio Access Network (E-UTRAN) nodeB (eNB) for an application executing at a user equipment (UE) in a long term evolution (LTE) wireless network environment, the handover request being sent by the first eNB to a second eNB, determining, at the second eNB, whether substantially all mandatory bearers required by the application can be accepted at the second eNB, and responding by the second eNB to the first eNB with a handover preparation failure message when substantially all mandatory bearers required by the application cannot be accepted at the second eNB. In specific embodiments, the handover request includes a list of substantially all mandatory bearers required by the application.

主权项

1. A method, comprising:
receiving a handover request from a first Evolved Universal Terrestrial Radio Access Network (E-UTRAN) nodeB (eNB) for an application executing at a user equipment (UE) in a long term evolution (LTE) wireless network environment, wherein the handover request is sent by the first eNB to a second eNB and includes an indication of mandatory bearers required by the application for using a packet data network (PDN) connection associated with the handover request, wherein the mandatory bearers comprise a portion of a plurality of bearers, wherein the mandatory bearers are specific to the application, wherein the indication comprises an additional bit in the handover request that is set only for mandatory bearers; determining, at the second eNB, whether all the mandatory bearers required by the application indicated in the handover request can be accepted at the second eNB, wherein the determining comprises examining the additional bit in the handover request at the second eNB; and responding by the second eNB to the first eNB with a handover preparation failure message when all the mandatory bearers required by the application cannot be accepted at the second eNB.
