A method and device for accessing a core network in an LTE system

Abstract

The invention relates to the wireless communication technology, discloses a method and a device for accessing a core network in a long term evolution (LTE) system, and aims at avoiding the situation of transmission data congestion when multiple base stations simultaneously access the core network. The method includes the following steps: a network side device judges whether a channel based on a stream control transmission protocol (SCTP) is established between the network side device and one base station according to a received SCTP message which is transmitted from the base station; if the judging result is yes, an interface S1 is established according to a relevant message, and the received message is transmitted through a first channel; and otherwise, a channel based on the SCTP is established firstly, then the interface S1 is established according to the relevant message, and then the received message is transmitted through a second channel. The message transmitted from the base station where the channel is already established, and the message transmitted from the base station where the channel is not established are respectively transmitted through different channels, and therefore the influence on service quality of the accessed base stations due to the situation of transmission data congestion when the multiple base stations simultaneously access the core network is avoided.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for accessing a core network in an LTE system. Background technique [0002] With the diversified development of terminals, the terminal has higher and higher requirements on the network system. Therefore, LTE (Long Term Evolution, Long Term Evolution) applications that can improve the performance of cell edge users, increase cell capacity and reduce system delay are born. LTE is a transition between 3G and 4G. It improves and enhances the air access technology of 3G, and adopts OFDM (Orthogonal Frequently-Division Multiplexing) MIMO (Multiple Input Multiple Output) as its wireless network. The only standard for evolution, it can provide a peak rate of 326Mbit / s downlink and 86Mbit / s uplink under a 20MHz spectrum bandwidth, meeting the requirements of low latency, low complexity, and low cost. [0003] In the LTE system, when the base s...

However, when a variety of business types need to be processed by the core network global board, since the bandwidth of the processing channel from the interface board to the global board is limited by the software processing capability, when there is a large amount of business traffic, there will still be transmission data. In the case of congestion, at this time, if software plane control is used to avoid transmission data congestion, it will undoubtedly consume huge equipment resources. Furthermore, using existing technologies to effectively avoid transmission data congestion requires a high cost
