US 10,219,207 B2 · Method and system for selective access control with ensured service continuity guarantees

Abstract

A method and system for providing a continued service to user equipment (UE) under overload conditions is disclosed. A primary network undertakes a protective measure under unable to serve conditions by commanding a change in the UE network access behavior so that the UE can move to the secondary PLMN. After receiving the indication from the primary network, the UE connects to the secondary network and continues to obtain the services from the secondary network. The secondary PLMN ID can be sent to the UE in system information. Further, the information like overload indication, secondary PLMN ID and the time for which the UE can obtain the services from the secondary PLMN ID can be sent to individual UEs over dedicated messages either on an Access Stratum (AS) message or over a Non Access Stratum (NAS) message.

Dependent claims

A method for performing an access control by a user equipment (UE) in a communication network, the method comprising:

receiving, from a first network, a message including information indicating a network failure if the UE is unable to be served by the first network;
selecting a candidate public land mobile network (PLMN) for a PLMN selection, wherein the UE does not select the first network as the candidate PLMN while a timer based on a timer value preconfigured by the first network is running;
and
performing the PLMN selection based on the information indicating the network failure, wherein the message further includes an identifier of a secondary PLMN and a time for which the UE is able to obtain a service by the secondary PLMN.
