Embodiment Construction

[0023] Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0024] figure 1 A GAC-enabled NR or LTE network is illustrated according to a novel aspect. The NR / LTE network 100 includes an application server (application server) 111, wherein the application server 111 communicates with multiple UEs (such as figure 1 The illustrated UE 114) communicates to provide various services. exist figure 1 In this example, a server 111 and a packet data network gateway (Packet Data Network Gateway, PDN GW) 113 belong to a part of a core network (core network) 110 . UE 114 and its serving base station (Base Station, NB) 115 belong to a part of radio access network (Radio Access Network, RAN) 120 . Server 111 communicates with UE 114 through PDN GW 113 , serving gateway (Gateway, GW) 116 and NB 115 . Mobility Management Entity (MME) 117 communicates with NB 115 , Serving GW 116 and PDN GW 113 for ...

Abstract

A generic access control procedure is proposed. Every action that is subject to access control is associated with an access category, and each access category is in turn associated with a set of access control parameters. From the APP layer, a UE detects an action that is subject to access control. The UE obtains and stores access categorization rules. In NAS layer, the UE determines the access category for the action. The UE then determines the set of access control parameters for the action. In AS layer, the UE finally applies the set of access control parameters to the action and makes a barring decision for the action. By defining a generic access control procedure and separating access control functions into NAS layer and AS layer, the generic access control is simplified and extendible.

Description

[0001] cross reference [0002] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Application 62 / 443,642, filed January 6, 2017, entitled "Generic Access Control." The entire content of the above application is incorporated herein by reference. technical field [0003] The present invention generally relates to New Radio (New Radio, NR) systems, and in particular to Generic Access Control (GAC) and barring (bar) mechanisms for User Equipment (User Equipment, UE) in NR systems . Background technique [0004] Modern networks use congestion control and congestion avoidance techniques to try to avoid network congestion. Long Term Evolution (LTE) defines (specifies) several limiting mechanisms for concurrent (concurrent) congestion control. Access Class Barring (AccessClass Barring, ACB) is a mechanism used to limit the number of simultaneous access attempts of some UEs. All UEs are members of one of ten randomly assigned mobile populations, defined a...
