Title:
移動電気通信ネットワークにおけるＵＥ能力情報の更新方法
Document Type and Number:
Japanese Patent JP5787971
Kind Code:
B2
Abstract:
The present invention relates to methods and arrangements for handling UE capability information a mobile telecommunications network wherein an eNodeB 100 receives 60 information regarding the UE capability information from the UE 120 and stores 70 the information. The eNodeB 100 sends 80 the UE capability information to the EPC, i.e. the MME 130. The MME 130 receives and stores 90 the UE capability information. When the UE 120 transits from idle to active state, does an initial attach or when a part of the UE capabilities have changed, it sends 10 a message Ma to the eNodeB 100 regarding the update. The eNodeB 100 receives the message and sends 20 it to the MME 130. The MME 130 sends 30 a response associated with the previously stored UE capability information to the eNodeB 100. The eNodeB 100 decides 40 if the UE capabilities stored in the MME 130 is up-to-date based on the message sent from the UE 120 and the received response from the MME 130. If the UE 120 holds updated UE capabilities the eNodeB 100 could request 50 updated UE capability information from the UE 120.
