  • Patent number: 10219207
    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.

  • Patent number: 10136352
    Abstract: Provided is a method of sending and receiving signals for a user equipment (UE) in a mobile communication system. The method may include: receiving a service reject message from a Mobility Management Entity (MME) under congestion; sending a message containing at least one piece of information determined based on the service reject message to a Mobile Switching Center (MSC); receiving a message containing camping cell information from a base station (eNB); and camping on a cell indicated by the camping cell information. In one embodiment, when an MM back-off timer is applied to the UE utilizing CSFB (or SMS over SGs) at the time of network congestion, the MSC or 2G/3G RAN node is notified that the MM back-off timer is running in the UE, so that the UE may camp not on an LTE cell but on a 2G/3G cell after CS service reception. Hence, it is possible to prevent call drops for MT services that may be caused by UE location registration failure due to the MM back-off timer.
