Handling of inactive parameters upon release and re-suspend

A User Equipment, UE, comprising:

• a radio interface;
• and
• processing circuitry associated with the radio interface, wherein the processing circuitry is configured to cause the UE to:
• transmit a Radio Resource Control, RRC, resume request message;
• in response to the RRC resume request message, receive an RRC connection release message with an indication for suspend;
• and
• in response to receiving the RRC connection release message with an indication for suspend, replace information in a stored Access Stratum, AS, context of the UE with new information wherein, to replace the information in the stored AS context of the UE, the processing circuitry is configured to cause the UE to:
• replace stored security context information with security context information comprised in the RRC connection release message;
• replace a stored Inactive Radio Network Temporary Identifier, I-RNTI, with an I-RNTI comprised in the RRC connection release message;
• replace a stored cell identity with a cell identity of a cell in which the UE sent the RRC resume request message and received the RRC connection release message;
• replace a stored physical cell identity with a physical cell identity of the cell in which the UE sent the RRC resume request message and received the RRC connection release message;
• or
• replace a stored Cell Radio Network Temporary Identifier, C-RNTI, with a C-RNTI obtained by the UE for the cell in which the UE sent the RRC resume request message and received the RRC connection release message.

A network node for updating a User Equipment, UE, Access Stratum, AS, context stored for a UE upon re-suspending the UE in response to a Radio Resource Control, RRC, resume request from the UE, the network node comprising:

• processing circuitry configured to cause the network node to:
• receive, from a UE, a RRC resume request message;
• in response to receiving the RRC resume request message, transmit, to the UE, an RRC connection release message with an indication for suspend;
• and
• in response to transmitting the RRC connection release message with an indication for suspend, replace information in a stored AS context of the UE with new information, wherein, to replace the information in the stored AS context of the UE, the processing circuitry is configured to cause the network node to:
• replace stored security context information with security context information comprised in the RRC connection release message;
• replace a stored Inactive Radio Network Temporary Identifier, I-RNTI, with an I-RNTI comprised in the RRC connection release message;
• replace a stored cell identity with a cell identity of a cell in which the UE sent the RRC resume request message and received the RRC connection release message;
• replace a stored physical cell identity with a physical cell identity of the cell in which the UE sent the RRC resume request message and received the RRC connection release message;
• or
• replace a stored Cell Radio Network Temporary Identifier, C-RNTI, with a C-RNTI obtained by the UE for the cell in which the UE sent the RRC resume request message and received the RRC connection release message.
