  • Publication number: 20170181016
    Abstract: The present invention provides a method and device for subscribing to an RLF report. An integration reference point manager configures a subscription condition for an RLF report for an integration reference point agent. The integration reference point manager obtains an RLF report that is sent by the integration reference point agent and satisfies the subscription condition. The present invention can avoid that a base station sends an RLF report obtained from a UE, to an IRPManager through an IRPAgent in a best-effort mode, thereby decreasing the load of information transferred between the IRPManager and the IRPAgent.
