Problems solved by technology

Although R12 defines a series of RAN access network selection and service offloading rules and auxiliary parameters, this rule-based trigger offloading mechanism can only achieve network selection and APN (Access Point Name) level offloading, and the granularity is still relatively coarse

Abstract

The invention requires protecting a data flow distribution method for LTE-A and WLAN based on an interconnection technique. According to the data flow distribution method, the deep infusion of WLAN and an LTE-A cellular network in the wireless network is required so as to solve the problem of explosive increase of mobile data traffic. A deep infusion scheme of the WLAN and the LTE-A is provided, the data flow distribution with the LTE-A is carried out by virtue of the interconnection technique. Data is processed by an LTE-A base station through a packet data convergence protocol and a radio link control layer and is forwarded by the TE-A base station, a WLAN AP MAC layer and a PHY layer. According to the scheme, the WLAN and the LTE-A can be uniformly dispatched according to the quality and load of a real-time wireless channel, so that the handling capacity of a user is greatly increased, and the deployment and maintenance costs of the WLAN are effectively lowered.

Description

technical field [0001] The invention relates to the technical field of mobile communication LTE-A, in particular to a data distribution method based on dual connection technology in different systems of LTE-A and WLAN. Background technique [0002] With the rapid development of wireless communication technology, more and more types of services are required by users. In the future, wireless networks will make full use of the complementary characteristics of different networks to realize the mutual integration of multiple networks and multiple services. Heterogeneous networks are a typical The form of network integration. Therefore, in order to improve user service experience, make full use of the WLAN already deployed by operators, and better perform wireless network load balancing, 3GPP RAN (Radio Access Network) started the research on interoperability between WLAN and 3GPP wireless network in R12, and RAN2 was established successively WLAN / 3GPP wireless interoperability S...
