Method and apparatus for DBNG-UP redundancy

An apparatus for Disaggregated Broadband Network Gateway-User Plane (DBNG-UP) redundancy, wherein the apparatus comprises a hardware processor configured to:

• configure a redundancy group instance on a Disaggregated Broadband Network Gateway-Control Plane (DBNG-CP), wherein redundancy group members managed by the DBNG-CP at least comprise a first DBNG-UP and a second DBNG-UP;
• perform, by the DBNG-CP, UP redundancy capability negotiation with the first DBNG-UP and the second DBNG-UP respectively, and perform active/standby specifying on the first DBNG-UP and the second DBNG-UP, wherein an UP redundancy group identifier information element is added to a Packet Forwarding Control Protocol (PFCP) association message to support the UP redundancy capability negotiation and the active/standby specifying;
• and
• in response to a user plane interface failure occurring in the first DBNG-UP, receive by the DBNG-CP, failure information reported by the first DBNG-UP, trigger protection switching of redundancy group members and notify status information of the redundancy group members, wherein an information element of a PFCP node report request message is extended to carry the failure information reported by the first DBNG-UP, and an information element of a PFCP node report response message is extended to carry the status information of the redundancy group members.

An electronic apparatus, comprising a memory, a processor, and a computer program which is stored on the memory and is executable by the processor, the processor is configured to execute the computer program to:

• configure a redundancy group instance on a Disaggregated Broadband Network Gateway-Control Plane (DBNG-CP), wherein redundancy group members managed by the DBNG-CP at least comprise a first DBNG-UP and a second DBNG-UP;
• perform, by the DBNG-CP, UP redundancy capability negotiation with the first DBNG-UP and the second DBNG-UP respectively, and perform active/standby specifying on the first DBNG-UP and the second DBNG-UP, wherein an UP redundancy group identifier information element is added to a Packet Forwarding Control Protocol (PFCP) association message to support the UP redundancy capability negotiation and the active/standby specifying;
• and
• in response to a user plane interface failure occurring in the first DBNG-UP, receive, by the DBNG-CP, failure information reported by the first DBNG-UP, trigger protection switching of redundancy group members, and notify status information of the redundancy group members, wherein an information element of a PFCP node report request message is extended to carry the failure information reported by the first DBNG-UP, and an information element of a PFCP node report response message is extended to carry the status information of the redundancy group members.
