Embodiment Construction

[0033] Reference is now made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0034] figure 1 An example LTE network 100 supporting an enhanced packet switched domain data interruption mechanism is described in accordance with a novel aspect. The LTE network 100 includes an application server including an IMS server 111 that can provide various services by communicating with a plurality of user equipments including a UE 114 . exist figure 1 Among them, the IMS server 111 and the PDN GW 113 belong to a part of the core network (Core Network, CN) CN 110 . UE 114 and its serving base station (Base Station, BS) BS 115 are part of a radio access network (Radio Access Network, RAN) RAN 120 . RAN 120 provides radio access to UE 114 through RATs. IMS Server 111 communicates with UE 114 through PDN GW 113 , Serving GW 116 and BS 115 . Mobility Management Entity (MME) 117 communicates with BS 115 , Serving Gateway 1...

Abstract

Solutions are proposed to facilitate the support of 3GPP PS_Data_Off feature. The PS_Data_Off feature prevents transport via 3GPP access of all IP packets except those related to 3GPP PS_Data_Off Exempt Services. In one example, signaling storms due to frequent PS_Data_Off reconfiguration are prevented. In another example, for multi-SIM devices and for devices that supporting WiFi access, UE reconfigures the PS_Data_Off feature upon a triggering condition is satisfied. In yet another example, upon status change of PS_Data_Off feature, UE initiates RAT change to improve performance, to reduce power consumption and cost, and to maintain service continuity. Furthermore, new AT commands and parameters are introduced to enable the PS_Data_Off feature.

Description

[0001] Cross References to Related Applications [0002] This application was filed on January 6, 2017 pursuant to 35 U.S.C. §119, and is the priority of U.S. Provisional Application No. 62 / 443,010, entitled "ENHANCED PS DOMAIN DATA-OFF MECHANISM", the subject matter of which is hereby incorporated as refer to. technical field [0003] The disclosed embodiments relate generally to wireless communications, and more specifically to methods of supporting enhanced packet-switched domain data interruption mechanisms in next generation mobile communication systems. Background technique [0004] Wireless communication networks have grown exponentially in recent years. A Long-Term Evolution (LTE) system can guarantee a high peak data rate, low delay, increased system capacity, and low operating cost due to a simplified network architecture. The LTE system, also known as the 4G system, also provides communication with technologies such as Global System for Mobile Communication (GS...
