The apparatus also has means for providing, to a network entity, a requested network slice selection assistance information based on the selected network slice simultaneous registration group. ## Claims ### Claim 1 An apparatus comprising: at least one processor; at least one memory storing instructions which when executed by the at least one processor cause the apparatus to perform at least: retrieving information associated with network slice selection; selecting a network slice simultaneous registration group using the information associated with network slice selection; and providing, to a network entity, a requested network slice selection assistance information based on the selected network slice simultaneous registration group, wherein the information associated with network slice selection comprises at least one of: a priority value for a network slice simultaneous registration group; a priority value for an application; a priority value associated with a traffic descriptor; or a priority value for single-network slice selection assistance information, and wherein the selecting comprises: determining an average priority value of the single-network slice selection assistance information in each network slice simultaneous registration group, that has been normalized using the number of single-network slice selection assistance information in each network slice simultaneous registration group; and selecting the network slice simultaneous registration group with the highest average priority value. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein the information associated with network slice selection comprises a priority value for a network slice access stratum group. ### Claim 3 (depends on 2) The apparatus according to claim 2, wherein the information associated with network slice selection comprises an indication to use the priority value of the network slice access stratum group when selecting the network slice simultaneous registration group. ### Claim 4 (depends on 1) The apparatus according to claim 1, wherein the selecting a network slice simultaneous registration group using the information associated with network slice selection comprises: selecting the network slice simultaneous registration group using: i) the information associated with network slice selection, and ii) single-network slice selection assistance information associated with an application used in a user equipment. ### Claim 5 (depends on 1) The apparatus according to claim 1, wherein the selecting a network slice simultaneous registration group using the information associated with network slice selection comprises: selecting the network slice simultaneous registration group using: i) the information associated with network slice selection, and ii) single-network slice selection assistance information associated with an existing protocol data unit session of a user equipment. ### Claim 6 (depends on 1) The apparatus according to claim 1, wherein the retrieving information associated with network slice selection comprises: receiving, via a user input, the information associated with network slice selection. ### Claim 7 (depends on 1) The apparatus according to claim 1, wherein the retrieving comprises at least one of: receiving from a network function or retrieving an accessible configuration. ### Claim 8 (depends on 1) The apparatus according to claim 1, wherein the providing comprises: determining at least one single-network slice selection assistance information associated with the selected network slice simultaneous registration group; and providing, to a network entity, a requested network slice selection assistance information comprising the determined at least one single-network slice selection assistance information. ### Claim 9 (depends on 1) The apparatus according to claim 1, wherein the information associated with network slice selection is received in one of: a registration accept message, a configuration update command message, and a manage user equipment policy command message. ### Claim 10 An apparatus comprising: at least one processor, at least one memory storing instructions of a network function, wherein the instructions when executed by the at least one processor causes the apparatus to at least perform: providing, to a user equipment, information associated with network slice selection, for the selection of a network slice simultaneous registration group at the user equipment, wherein the information associated with network slice selection comprises at least one of: a priority value for a network slice simultaneous registration group; a priority value for an application; a priority value associated with a traffic descriptor; or a priority value for single-network slice selection assistance information; and receiving, from the user equipment, a requested network slice selection assistance information based on a first network slice simultaneous registration group selected by the user equipment based on a determination of an average priority value of the single-network slice selection assistance information in each network slice simultaneous registration group, that has been normalized using the number of single-network slice selection assistance information in each network slice simultaneous registration group and a determination of the network slice simultaneous registration group with the highest average priority value. ### Claim 11 (depends on 10) The apparatus according to claim 10, wherein the information associated with network slice selection comprises a priority value for a network slice access stratum group. ### Claim 12 (depends on 11) The apparatus according to claim 11, wherein the information associated with network slice selection comprises an indication to use the priority value of the network slice access stratum group when selecting the network slice simultaneous registration group. ### Claim 13 (depends on 10) The apparatus according to claim 10, wherein the information associated with network slice selection comprises at least one of: a priority value for a network slice simultaneous registration group; a priority value for an application; a priority value associated with a traffic descriptor; or a priority value for single-network slice selection assistance information. ### Claim 14 A method comprising: retrieving, by an apparatus, information associated with network slice selection; selecting, by the apparatus a network slice simultaneous registration group using the information associated with network slice selection; and providing, by the apparatus to a network entity, a requested network slice selection assistance information based on the selected network slice simultaneous registration group, wherein the information associated with network slice selection comprises at least one of: a priority value for a network slice simultaneous registration group;
