Abstract
An NR network slicing architecture may be used to facilitate network slice discovery and selection. Mechanisms to discover and select network slices may differ depending on whether a user equipment is in an idle mode or a connected mode. Further, in various examples, the network slice discovery and selection may be performed by a UE, a radio access network (RAN), or a core network (CN), based on a variety of selection criteria.
Claims20
A wireless transmit/receive unit (WTRU), comprising a transceiver and one or more processors, configured to:
- send slice selection assistance information and a 5G globally unique temporary identity to a network, the slice selection assistance information indicating slice service type information;
- receive an indication of a first slice that the WTRU is allowed to access;
- receive, in one or more system information blocks (SIBs), slice information that indicates one or more slices supported by one or more cells in the network, wherein the one or more SIBs indicate at least one set of random access resources associated with accessing at least the first slice;
- select a first cell based on the first cell supporting access to the first slice;
- select the set of random access resources indicated as being associated with accessing at least the first slice in the one or more SIBs;
- and
- send, via the first cell, an access request using the random access resources indicated as being associated with accessing at least the first slice in the one or more SIBs.
An apparatus, comprising a transceiver and one or more processors configured to:
- receive slice selection assistance information and a 5G globally unique temporary identity from a wireless transmit/receive unit (WTRU), the slice selection assistance information indicating slice service type information;
- send an indication of a first slice that the WTRU is allowed to access;
- send, to the WTRU in one or more system information blocks (SIBs), slice information that indicates one or more slices supported by a network, wherein the one or more SIBs indicate at least one set of random access resources associated with accessing at least the first slice;
- and
- receive, from the WTRU, an access request associated with the set of random access resources indicated as being associated with accessing at least the first slice in the one or more SIBs selected by the WTRU.
A method for use in a wireless transmit/receive unit (WTRU) comprising:
- sending slice selection assistance information and a 5G globally unique temporary identity to a network, the slice selection assistance information indicating slice service type information;
- receiving an indication of a first slice that the WTRU is allowed to access;
- receiving, in one or more system information blocks (SIBs), slice information that indicates one or more slices supported by one or more cells in the network, wherein the one or more SIBs indicate at least one set of random access resources associated with accessing at least the first slice;
- selecting a first cell based on the first cell supporting access to the first slice;
- selecting the set of random access resources indicated as being associated with accessing at least the first slice in the one or more SIBs;
- and
- sending, via the first cell, an access request using the random access resources indicated as being associated with accessing at least the first slice in the one or more SIBs.
