Resuming a connection in a wireless communication system

A user equipment comprising:

• processing circuitry to:
• receive, from a source radio access network (RAN) node with which the user equipment has a connection, a message indicating that the connection is to be suspended and indicating a resume identifier usable by the user equipment to resume the connection after the connection is suspended;
• while the connection is suspended, transmit to a target RAN node a request to resume the connection, wherein the request includes the resume identifier;
• and
• transmit to the target RAN node an indication of a public land mobile network (PLMN) with which the resume identifier is associated, wherein the indication of the PLMN with which the resume identifier is associated comprises an index of a specific PLMN identity in a list of PLMN identities, wherein each PLMN identity in the list has an associated index.

A non-transitory device-readable medium having stored thereon instructions that, when executed by processing circuitry of a user equipment, cause the user equipment to:

• receive, from a source radio access network (RAN) node with which the user equipment has a connection, a message indicating that the connection is to be suspended and indicating a resume identifier usable by the user equipment to resume the connection after the connection is suspended;
• while the connection is suspended, transmit to a target RAN node a request to resume the connection, wherein the request includes the resume identifier;
• and
• transmit to the target RAN node an indication of a public land mobile network (PLMN) with which the resume identifier is associated, wherein the indication of the PLMN with which the resume identifier is associated comprises an index of a specific PLMN identity in a list of PLMN identities, wherein each PLMN identity in the list has an associated index.
