Title:
PERFORMANCE ENHANCEMENT ON PS DATA-OFF
Document Type and Number:
WIPO Patent Application WO/2019/214741
Kind Code:
A1
Abstract:
A method of modifying PS_Data_Off status via a PDN connection modification procedure and interpreting network PS_Data_Off support feature is proposed. A UE modifies the PS data off status by using a bearer resource modification procedure. The UE receives a response to the modification request and monitors whether the response includes the 3GPP PS_Data_Off Support Indication. In one embodiment, if the network does not provide the 3GPP PS_Data_Off Support Indication, the UE thinks that the network does not support PS data off feature regardless whether the network accept or reject the modification request. In another embodiment, if the network does not provide the 3GPP PS_Data_Off Support Indication, then UE thinks that the network supports PS data off feature if it accepts the modification request, and does not support PS data off feature if it rejects the modification request.
