Procedures to support network slicing in a wireless communication system
First Claim
1. A method comprising:
- establishing, at a remote unit, a first connection with a primary network slice of a mobile communication network, the primary network slice providing service for one or more usage classes;
establishing, at the remote unit, a second connection with a secondary network slice of the mobile communication network while maintaining the first connection, the secondary network slice providing service for one or more additional usage classes;
detecting a mobility management event for the remote unit; and
transmitting a single mobility management request to the primary network slice via the first connection in response to the mobility management event; and
receiving a consolidated mobility management response via the first connection, wherein the consolidated mobility management response includes a first response from the primary network slice that indicates whether the primary network slice accepts the mobility management request and a second response from the secondary network slice that indicates whether the secondary network slice accepts the mobility management request.

Abstract
Apparatuses, methods, and systems are disclosed for mobility management among multiple network slices. One apparatus includes a processor that receives a mobility management request from the mobile unit and forwards the mobility management request to the secondary network slice. Here, the mobile unit is simultaneously served by the primary network slice and a secondary network slice of the mobile communication network. The apparatus sends a single mobility management response to the mobile unit, wherein the single mobility management response includes a first response from the primary network slice and a second response from the secondary network slice. In various embodiments, the apparatus may include a network interface for communicating over a mobile communication network.
