Abstract
Methods, systems, and devices for wireless communications are described. Generally, the described techniques at a network provide for efficiently considering parameters of a network slice when determining whether to provide access to the network slice, allow the establishment of a session via the network slice, or grant access to resources for communications via the network slice. Further, the described techniques at a user equipment (UE) provide for efficiently determining when or whether to retry to access a network slice, retry to establish a session via the network slice, or retry to access resources for communicating via the network slice.
Claims20
An apparatus for wireless communication at a user equipment (UE), comprising:
- one or more memories storing processor-executable code;
- and
- one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
- send, to a network entity, a first request for access to a network slice of a plurality of network slices, the first request comprising an identifier of the network slice;
- receive, in a first control message from the network entity, an indication of a cause for rejecting access to the network slice;
- and
- receive, in the first control message, one or more single network slice selection assistance information (S-NSSAI) values and one or more tracking area identity values associated with the one or more S-NSSAI values, wherein the one or more tracking area identity values correspond to a second geographic coverage area where access to the network slice is allowed based at least in part on a UE route selection policy (URSP), and wherein the second geographic coverage area is different from a first geographic coverage area where access to the network slice is rejected.
A method for wireless communication at a user equipment (UE), comprising:
- sending, to a network entity, a first request for access to a network slice of a plurality of network slices, the first request comprising an identifier of the network slice;
- receiving, in a first control message from the network entity, an indication of a cause for rejecting access to the network slice;
- and
- receiving, in the first control message, one or more single network slice selection assistance information (S-NSSAI) values and one or more tracking area identity values associated with the one or more S-NSSAI values, wherein the one or more tracking area identity values correspond to a second geographic coverage area where access to the network slice is allowed based at least in part on a UE route selection policy (URSP), and wherein the second geographic coverage area is different from a first geographic coverage area where access to the network slice is rejected.
A non-transitory computer-readable medium storing code for wireless communications, the code comprising instructions executable by one or more processors to:
- send, to a network entity, a first request for access to a network slice of a plurality of network slices, the first request comprising an identifier of the network slice;
- receive, in a first control message from the network entity, an indication of a cause for rejecting access to the network slice;
- and
- receive, in the first control message, one or more single network slice selection assistance information (S-NSSAI) values and one or more tracking area identity values associated with the one or more S-NSSAI values, wherein the one or more tracking area identity values correspond to a second geographic coverage area where access to the network slice is allowed based at least in part on a user equipment (UE) route selection policy (URSP), and wherein the second geographic coverage area is different from a first geographic coverage area where access to the network slice is rejected.
