Grouping of network slices for dedicated network slice information

A wireless terminal comprising:

• receiver circuitry configured to receive a customized mapping configuration and to receive a message dedicated to the wireless terminal, the customized mapping configuration configuring one or more network slice groups, each of the one or more network slice groups comprising one or more network slices identified by respective Single Network Slice Selection Assistance Information (S-NSSAI) in Configured NSSAI provisioned in the wireless terminal, each of the one or more network slice groups being identified by a corresponding group index, the message comprising one or more group indices, the one or more group indices being associated with respective list(s) of one or more radio frequencies;
• and
• processor circuitry configured to:
• determine, based on one of the list(s), a radio frequency(ies) on which a network slice group from the one or more network slice groups is supported;
• and
• perform a cell reselection procedure on the radio frequency(ies).

A method performed by a wireless terminal, the method comprising:

• receiving a customized mapping configuration configuring one or more network slice groups, each of the one or more network slice groups comprising one or more network slices identified by respective Single Network Slice Selection Assistance Information (S-NSSAI) in Configured NSSAI provisioned in the wireless terminal, each of the one or more network slice groups being identified by a corresponding group index;
• receiving a message dedicated to the wireless terminal, the message comprising one or more group indices, the one or more group indices being associated with respective list(s) of one or more radio frequencies;
• determining, based on one of the list(s), a radio frequency(ies) on which a network slice group from the one or more network slice groups is supported;
• and
• performing a cell reselection procedure on the radio frequency(ies).

A base station comprising:

• processor circuitry configured to generate a customized mapping configuration and to generate a message dedicated to a wireless terminal, the customized mapping configuration configuring one or more network slice groups, each of the one or more network slice groups comprising one or more network slices identified by respective Single Network Slice Selection Assistance Information (S-NSSAI) in Configured NSSAI provisioned in the wireless terminal, each of the one or more network slice groups being identified by a corresponding group index, the message comprising one or more group indices, the one or more group indices being associated with respective list(s) of one or more radio frequencies;
• and
• transmitting circuitry configured to transmit the customized mapping configuration and the message to the wireless terminal, wherein
• the customized mapping configuration and the message cause the wireless terminal to:
• determine, based on one of the list(s), a radio frequency(ies) on which a network slice group from the one or more network slice groups is supported;
• and
• perform a cell reselection procedure on the radio frequency(ies).
