Abstract
Embodiments of the present disclosure are directed to systems and methods for improved identification and resolution of conflicting session information, such as when multiple session information entries are associated with a single session identifier. By communicating timestamps with the session information deposited in the NF component, the NF component may determine which session information is relevant to the request or which session information is stale and should be removed from its dataset.
Claims20
A method for managing session information in a core network, the method comprising:
- receiving, at a first network function (NF) component, first session information from a second NF component, the first session information comprising a first timestamp, a first device identifier, and a first session identifier;
- creating, by the first NF component, a first entry in a locally stored dataset, the first entry comprising the first session information;
- receiving, at the first NF component, second session information from the second NF component, the second session information comprising a second timestamp, a second device identifier, and the first session identifier;
- creating, by the first NF component, a second entry in the locally stored dataset, the second entry comprising the second session information;
- determining the first entry is stale as compared to the second entry;
- and p21 removing, based on the determinations, the first entry from the locally stored dataset.
A method for managing session information in a core network, the method comprising:
- receiving, at a first network function (NF) component, first session information, the first session information comprising a first session identifier, a first device identifier, and a first timestamp;
- receiving, at the first NF component, second session information, the second session information comprises the first session identifier, a second device identifier, and a second timestamp;
- receiving, at the first NF component, a request for session information associated with the first session identifier;
- in response to the request for session information, determining the first session information is stale as compared to the second session information;
- and
- communicating, based on the determination, the second session information in response to the request for session information.
A system for managing session information in a core network, the system comprising:
- a network function (NF) consumer configured to perform operations comprising:
- communicating a request for session information associated with a first session identifier to an NF producer;
- and
- the NF producer configured to perform operations comprising:
- receiving first session information from a policy control function (PCF) for a first session, the first session information comprising a first timestamp, a first device identifier, and a first session identifier;
- receiving second session information from the PCF for a second session, the second session information comprising a second timestamp, a second device identifier, and the first session identifier;
- in response to the request, determining the second timestamp is more recent than the first timestamp;
- and
- communicating, based on the determination, the second session information to the NF consumer.
