Method and device for segmentation processing of user plane tunnel terminal identifier teid-u of terminal

Abstract

Embodiments of the present invention provide a method and device for segmenting the user plane tunnel terminal identifier TEID-U of a terminal. The terminal includes a service board, and the TEID-U includes a service board identifier and a TEID-U lower-level identifier. The method includes: determining the number of service boards of the terminal; determining the first number of bits occupied by the service board identifier in the TEID-U according to the number of service boards, and determining that the TEID-U subordinate identifier is in the TEID-U The second number of bits occupied; based on the first number of bits, assign a first identifier to the service board identifier; based on the second number of bits, assign a second identifier to the TEID-U lower-level identifier; merge the The first identity and said second identity obtain TEID-U. The embodiment of the present invention makes it unnecessary for the service board to apply for TEID-U resources from the global board through inter-board communication, and does not require the global board to perform resource management for TEID-U, and can ensure the allocation of TEID-U when multiple service boards exist. No duplication will occur.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for segmenting the user plane tunnel terminal identifier TEID-U of a terminal. Background technique [0002] In EPC (Evolved Packet Core, Evolved Packet Core Network), the data flow of the user plane is based on bearer transmission. For a bearer, that is, a GTP-U (GPRS Tunneling Protocol for the user plane, user plane GPRS tunneling protocol) The tunnel corresponds to an IP address, port (UDP (User Datagram Protocol, User Datagram Protocol) port) and TEID-U (Tunnel Endpoint Identifier, User plane; tunnel endpoint identifier, user plane). Wherein, TEID-U is included in the packet header of the GTP protocol, and is a 4-byte integer number. The SGW (Serving Gateway, Serving Gateway) and PGW (Public Data Network Gateway, Public Data Gateway) devices in the EPC are responsible for data transmission on the user plane. Generally, the IP addresse...

Problems solved by technology

[0006] Disadvantage 1: It occupies more memory resources. Although a TEID-U only occupies 4 bytes, due to the large number, when TEID-U resources are managed as global resources of the device, more memory resources are required.

[0007] Disadvantage 2: When applying for TEID-U resources, the service board needs to communicate with the global board, which involves inter-board communication

When the inter-board communication is abnormal, the resources of the global board and the TEID-U resources of the service board will be inconsistent, but the actual handling of the abnormal situation is more troublesome
