US 2023/0403756 A1 · USER EQUIPMENT CONTEXT RETRIEVAL IN RADIO RESOURCE CONTROL INACTIVE STATE

Abstract

Techniques are provided for enabling user equipment (UE) context retrieval in radio resource control RRC inactive status with a shared radio access network (RAN) database (DB) within a distributed database architecture. A version indicator in an inactive Radio Network Temporary Identifier (I-RNTI) is populated by the UE to indicate one or more I-RNTI versions, defined herein, and indicates the type of data in the remainder of the I-RNTI used for communicating the location of a RAN DB that stores the UE context, to a target network node. The target network node then uses the data in the I-RNTI, further dependent on the I-RNTI version, to retrieve the UE content from the RAN database. Certain embodiments utilize a RAN DB Area (RDBA) and/or RAN DB Set Area (RDSA), and certain embodiments utilize a network node set ID.

An apparatus comprising:

at least one processor and at least one memory including computer program code,
the at least one memory and the computer program code being configured to, with the processor, cause the apparatus to at least:
receive, from a source network node, a connection release message comprising at least one inactive radio network temporary identifier (I-RNTI) version associated with at least one of a source radio access network database area (RDBA) or a source radio access network database set area (RDSA);
and
generate a connection resume request based on the received I-RNTI version.
