Abstract

Several aspects of this disclosure relate to techniques for indirect network sharing. An appliance is configured to receive a first message to register a UE on a participating network associated with a host network, transmit a second message comprising support information based, at least in part, on the first message received, wherein the support information comprises NSSAI permitted for the UE or NSSAI partially permitted for the UE, or both, and wherein each of the permitted NSSAI or NSSAI partially permitted, or both, is associated with the corresponding permitted NSSAI or NSSAI partially permitted associated with the host network, and transmit a third message to a second network entity of the host network, the third message comprising NSSAI permitted or NSSAI partially permitted, or both, associated with the host network corresponding to the NSSAI permitted or NSSAI partially permitted for the UE, or both.

Description

TECHNICAL AREA [0001]This disclosure relates to wireless communications and, more specifically, to techniques for indirect network sharing. BACKGROUND [0002]A wireless communications system may include one or multiple network communication devices, such as base stations (BSs), which may support wireless communications to one or multiple user communication devices, which may also be known as user equipment (UE) or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices, utilizing wireless communications system features (e.g., timing features (e.g., symbols, slots, subframes, frames, or the like) or frequency features (e.g., subcarriers, carriers, or the like). In addition, the wireless communications system may support wireless communications in various radio access technologies, including third-generation (3G) radio access technology, fourth-generation (4G) radio access technology, fifth-generation (5G) radio access technology, among other suitable radio access technologies besides 5G (e.g., sixth generation (6G)). SUMMARY [0003] An article "a" before an element is unrestricted and understood as referring to "at least one" of those elements or to "one or more" of those elements. The terms "a", "at least one", "one or more", and "at least one of one or more" may be interchangeable. As used in this document, including in the claims, "or", as used in a list of items (for example, a list of items preceded by a phrase such as "at least one of" or "one or more of" or "one or both of") indicates an inclusive list, so that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Furthermore, as used in this document, the phrase "based on" should not be interpreted as a reference to a closed set of conditions. For example, an example step described as "based on condition A" may be based on either condition A or condition B, without departing from the scope of this disclosure. In other words, as used in this document, the expression "based on" should be interpreted in the same way as the expression "based at least in part on". Furthermore, as used in this document, including in the claims, a "set" may include one or more elements. [0004]In one embodiment, an appliance may be configured to receive a first message to register an UE with a participating network associated with a host network, transmit a second message comprising assistance information based at least in part on the first message received, wherein the assistance information comprises network slice selection assistance information (NSSAI) permitted for the UE or partially permitted NSSAI for the UE, or both, and wherein each of the permitted NSSAI or partially permitted NSSAI, or both, is associated with the corresponding permitted NSSAI or the corresponding partially permitted NSSAI associated with the host network, and transmit a third message to a second network entity of the host network, the third message comprising permitted NSSAI or partially permitted NSSAI, or both, associated with the host network corresponding to the permitted NSSAI or the partially permitted NSSAI for the UE, or both.
