Methods and UE for resuming a connection with full configuration

A wireless device, comprising a communication interface;

• and one or more processing circuits communicatively connected to the communication interface, the one or more processing circuits comprising at least one processor and memory, the memory containing instructions that, when executed, cause the at least one processor to:
• send to a network node a request to resume a connection in a communication network;
• receive a resume response message from the network node, the resume message comprising new User Equipment (UE) context information generated by the network node based at least on interface information between the network node and a core network and in response to determining that a retrieved UE context information is unidentifiable, the resume message further comprising a flag set to full configuration, wherein the resume message is a Radio Resource Control (RRC) resume message which is distinct from a RRC connection reconfiguration message;
• and
• in response to receiving the resume message, apply the full configuration.

A first network node comprising:

• a communication interface;
• and
• one or more processing circuits communicatively connected to the communication interface, the one or more processing circuits comprising at least one processors and memory, the memory containing instructions that, when executed, cause the at least one processor to:
• receive, from a wireless device, a request to resume a connection in a communication network;
• based on the request, retrieving User Equipment (UE) context information from a second network node;
• determining that the retrieved UE context information is unidentifiable;
• in response to the determining, generating new UE context information based at least on interface information between the first network node and a core network;
• and
• send a resume message to the wireless device, the resume message comprising the new UE context information and a flag set to full configuration, wherein the resume message is a Radio Resource Control (RRC) resume message which is distinct from a RRC connection reconfiguration message.
