Method and system for user information management

A method for wireless communication, comprising:

• transmitting, by a centralized unit to a distributed unit that is in communication with the centralized unit via a fronthaul interface, a setup request message for establishing a user equipment (UE) radio bearer context, wherein the setup request message comprises a first application-layer protocol (AP) identifier (ID) allocated by the centralized unit to uniquely identify the UE and configuration information about one or more signaling radio bearers;
• receiving, by the centralized unit, a setup response message from the distributed unit indicating that the distributed unit has established the UE radio bearer context, wherein the setup response message comprises the first AP ID allocated by the centralized unit to uniquely identify the UE, a second AP ID allocated by the distributed unit to uniquely identify the UE, and configuration information about one or more signal radio bearers set up by the distributed unit;
• transmitting, from the centralized unit to the distributed unit, a reconfiguration request message for modifying the UE radio bearer context, wherein the reconfiguration request message comprises the first AP ID allocated by the centralized unit to uniquely identify the UE, the second AP ID allocated by the distributed unit to uniquely identify the UE, and configuration information about one or more data radio bearers;
• and
• receiving, by the centralized unit, a reconfiguration response message from the distributed unit indicating that the distributed unit has modified the UE radio bearer context, wherein the reconfiguration response message includes the first AP ID allocated by the centralized unit to uniquely identify the UE, the second AP ID allocated by the distributed unit to uniquely identify the UE, and a list of modified data radio bearers.
