USER EQUIPMENT CONTEXT RETRIEVAL IN RADIO RESOURCE CONTROL INACTIVE STATE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18321409 titled 'USER EQUIPMENT CONTEXT RETRIEVAL IN RADIO RESOURCE CONTROL INACTIVE STATE

Simplified Explanation

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.
• The version indicator in the I-RNTI is used to communicate the location of a RAN DB that stores the UE context to a target network node.
• The target network node uses the data in the I-RNTI, 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) for efficient retrieval of UE context.
• Certain embodiments utilize a network node set ID to further enhance the retrieval process.

Potential Applications

• This technology can be applied in cellular networks to enable efficient retrieval of user equipment context in radio resource control inactive status.
• It can be used in scenarios where a shared radio access network database is employed within a distributed database architecture.

Problems Solved

• Retrieving user equipment context in radio resource control inactive status can be challenging in distributed database architectures.
• The location of the database storing the user equipment context needs to be communicated accurately to the target network node.

Benefits

• Enables efficient retrieval of user equipment context in radio resource control inactive status.
• Simplifies the communication of the database location to the target network node.
• Improves the overall performance and reliability of cellular networks.

Original Abstract Submitted

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.
