Embodiment Construction

[0028] In order for those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention are described below in conjunction with the accompanying drawings. The program is described in more detail.

[0029] Firstly, the technology adopted in the present invention is introduced, including the balancing method according to the interface type, the SGW IP address learning, and the balancing method according to the user IP address modulo.

[0030] The balancing method by interface type refers to: UDP or SCTP is judged according to the upper layer protocol field protocol in the IP header, UDP is the user datagram protocol, and SCTP is the stream control transmission protocol. If it is a UDP message, analyze the UDP header to judge ...

Abstract

The invention provides a load balancing method of LTE (Long Term Evolution) core network interface large traffic data. S1-MME, S10 / S11, S6a and S1-U protocol messages are distinguished for data which are accessed from a bypass of an LTE core network, the S1-MME, S10 / S11, S6a and S1-U protocol messages are forwarded to corresponding signal processing boards respectively, user IPs (Internet Protocol) in the S1-U massage are resolved for large traffic S1-U user service data, and the S1-U massage is distributed to a plurality of user service data processing boards according to IP addresses of users in a modulus mode. According to the load balancing method of the LTE core network interface large traffic data, the large traffic data accessed from an S1-U interface can be sent to a plurality of protocol resolution board cards in a balanced mode to be processed and the data of every user can be on the same protocol resolution board card and accordingly the subsequent processing requirements of the distributed data for the user data are met.

Description

technical field [0001] The invention belongs to the technical field of LTE network communication, and in particular relates to a load balancing method for large flow data of an LTE core network interface. Background technique [0002] LTE is the abbreviation of Long Term Evolution. The full name should be 3GPP Long Term Evolution. Chinese is generally translated as 3GPP long-term evolution technology. It is the third generation partnership project (3GPP) standard. The delay of small IP data packets is less than 5ms, acceptable for terminals to be used in different frequency bands at a moving speed of 350Km / h or 500Km / h, support frequency division duplex and time division duplex communication, support 1.4MHz, 3MHz, 5MHz, 10MHz , 15MHz and 20MHz frequency bandwidth and other characteristics. [0003] With the issuance of LTE licenses at the end of 2013, the 4G mobile network was officially put into operation. While the LTE network brought higher bandwidth and better experienc...
