A system and method for realizing multi-standard wireless terminal binding

Abstract

The present invention discloses a system and method for realizing multi-standard wireless terminal binding, wherein the method includes: after the terminal establishes user plane data bearer with the wireless network node of the current standard, initializing negotiation with the wireless network node; If the network node acts as the anchor point for cross-standard bearer binding, it will learn through initialization negotiation that the corresponding terminal supports multi-standard binding, and after the cross-standard bearer binding of the terminal is triggered and established, it will be bound with the terminal of other standards. Interaction between the wireless network node and the terminal establishes the association relationship of the multi-standard context of the terminal. The present invention solves many problems in distributing downlink data, routing and mobility management under multi-standard channels, and by controlling the anchor point, the system performance caused by possible packet loss in the process of multi-standard distribution and mobility of a single stream is avoided. decline.

Description

technical field [0001] The invention relates to the fusion technology of multi-standard mobile communication systems, in particular to a system and method for realizing multi-standard wireless terminal binding under the condition that multi-standard mobile communication systems coexist. Background technique [0002] With the continuous evolution of wireless communication technologies and standards, mobile packet services have been greatly developed, and the data throughput capability of a single terminal is constantly improving. Taking the Long Term Evolution (LTE, Long Term Evolution) system as an example, it can support data transmission at a maximum downlink rate of 100 Mbps within a 20M bandwidth. In the subsequent enhanced LTE (LTE Advanced) system, the data transmission rate will be further increased. [0003] However, the data throughput rate of a single terminal depends not only on the wireless technology used, but also on the bandwidth occupied by the channel, the c...

[0007] (2) The transmission path delays of different standards are inconsistent, which will cause the transmission control protocol (TCP, Transmission Control Protocol) layer / IP layer data packets to not arrive in order, thus causing repeated confirmation at the TCP layer, so that the network enters a congestion avoidance state, which It will affect the efficiency of data transmission;

[0009] (4) Since the existing protocol system frameworks of different standards have been determined, the binding of multiple standard terminals requires the existing non-access stratum (NAS, Non-AccessStratum) and access stratum (AS, AccessStratum) Changes to the control protocol require a long-term standardization process, as well as changes to the underlying protocol layer of the terminal. Therefore, it is impossible to quickly promote the progress of LTE industrialization
