Abstract
A mechanism is provided to monitor and control the number of terminals (100) or number of PDU sessions for a network slice, or both. A new network function called the Network Slice Control Function (NSCF) (85) is defined that interacts with an Access and Mobility Management Function (AMF) (40) and/or Session Management Function (SMF) (45) to monitor and control a number of users for a network slice, a number of PDU sessions for a network slice, or both. The NSCF (85) determines per slice quotas for the number of users and/or number of session for network slices and interacts with the AMF (40) and/or SMF (45) to enforce the quotas.
Claims12
A method implemented by a network node in a wireless communication network, the method comprising the network node:
- receiving a registration request from a user to use a network slice, the registration request including a network slice identifier for the network slice;
- receiving network slice control information from a network slice control node, wherein the network slice control information comprises a binary indication for each of one or more network slices indicating either that a quota for the network slice has been reached or that the quota for the network slice has not been reached;
- and
- controlling use of the network slice based at least in part on the indication.
A network node in a wireless communication network, the network node comprising:
- interface circuitry for communicating over a communication network with other network nodes;
- and
- processing circuitry configured to:
- receive a registration request from a user to use a network slice, the registration request including a network slice identifier for the network slice;
- receive network slice control information associated with the network slice identifier from a network slice control node, wherein the network slice control information comprises a binary indication for each of one or more network slices indicating either that a quota for the network slice has been reached or that the quota for the network slice has not been reached;
- and
- control use of the network slice based at least in part on the quota.
