Problems solved by technology

Therefore, all 5GS files cannot be assigned SFI
5GS file access will be more efficient
Also, next-gen SIM files face the same issues as 5GS

Embodiment Construction

[0022] Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0023] figure 1 An exemplary wireless communication network 100 according to an embodiment of the present invention is illustrated, the network has UEs supporting 5G features with efficient FID and SFI in USIM ADF. The wireless communication system 100 may include one or more fixed infrastructure elements forming a network distributed over a geographical area. The above-mentioned basic unit may also be called an access point (access point), an access terminal (access terminal), a base station (Base Station, BS), a node B (Node-B), an evolved node B (eNode-B, eNB) , gNB or other terms used in this technical field. exist figure 1 In one or more BSs 101 and 102, a plurality of remote terminals / UEs 103, 104, and 105 may be served within a service area (eg, a cell) or within a sector of a cell. In some systems, one or more BSs are...

Abstract

Methods and apparatus are provided for efficiently operating of USIM FIDs and SFIs under USIM ADF. In one novel aspect, the UICC of the mobile equipment comprises one or more generation dedicated files (DFs), and one or more generation-dedicated elementary files (EFs) are stored in each corresponding generation DF. In one embodiment, at least one of the generation-dedicated EFs is assigned an SFI.In another embodiment, each generation-dedicated EFs is assigned an SFI. In yet another embodiment, all generation-dedicated EFs for one generation are stored in corresponding generation DF. In one embodiment, at least one of the 5GS EFs is associated with at least one of: 5GS 3GPP location information, 5GS non-3GPP location information, 5GS 3GPP Access NAS Security Context, non-5GS 3GPP Access NAS Security Context, and 5G authentication keys.

Description

[0001] cross reference [0002] This application claims priority under 35 U.S.C.§119 to U.S. Provisional Application 62 / 694,153 filed on July 5, 2018, entitled "SolveInsufficiency of FIDs and SFIs under USIM ADF", the contents of which are incorporated by reference into the present invention. technical field [0003] The present invention relates generally to wireless communications, and in particular to efficient File Identifiers (FIDs) and short File Identifier (Short FileIdentifier, SFI). Background technique [0004] A Universal Integrated Circuit Card (UICC) or a Subscriber Identity Module (SIM) card is widely used in cellular phones for mobile communication networks. There are many applications in the UICC, such as USIM applications and Code Division Multiple Access (CDMA) SIM (CSIM) applications. The USIM application brings security improvements such as mutual authentication and longer encryption keys and an improved address book. A USIM application is composed o...
