Abstract
An improved cellular network architecture enables the distribution of Radio Resource Control (RRC) inactive state to devices in a core network. A mobility manager receives subscription requests from core network devices requesting notification of user equipment (UE) transitions to RRC Inactive states. Upon receiving an RRC transition report for a UE that indicates a transition to an RRC Inactive state, the mobility manager publishes an event including data representing the RRC inactive state and a UE identifier. Subscribing network elements receive this event and can adjust operations accordingly, including temporarily suspending operations until a further RRC state change.
Claims20
A method comprising:
- receiving, by a processor, a subscription request from a computing device, the subscription request including a radio resource control (RRC) inactive state status subscription type;
- receiving, by the processor, a transition report indicating that a user equipment (UE) has entered an RRC inactive state;
- identifying, by the processor, a set of listeners using an identifier of the UE, the set of listeners including the computing device;
- generating, by the processor, an event responsive to the transition report, the event including data representing the RRC inactive state and an identifier of the UE;
- and
- publishing, by the processor, the event to the set of listeners.
A non-transitory computer-readable storage medium for storing instructions capable of being executed by a processor, the instructions defining steps of:
- receiving, by the processor, a subscription request from a computing device, the subscription request including a radio resource control (RRC) inactive state status subscription type;
- receiving, by the processor, a transition report indicating that a user equipment (UE) has entered an RRC inactive state;
- identifying, by the processor, a set of listeners using an identifier of the UE, the set of listeners including the computing device;
- generating, by the processor, an event responsive to the transition report, the event including data representing the RRC inactive state and an identifier of the UE;
- and
- publishing, by the processor, the event to the set of listeners.
A device comprising:
- a processor configured to:
- receive a subscription request from a computing device, the subscription request including a radio resource control (RRC) inactive state status subscription type;
- receive a transition report indicating that a user equipment (UE) has entered an RRC inactive state;
- identify a set of listeners using an identifier of the UE, the set of listeners including the computing device;
- generate an event responsive to the transition report, the event including data representing the RRC inactive state and an identifier of the UE;
- and
- publish the event to the set of listeners.
