Problems solved by technology

[0010] In the process of realizing the present invention, the inventor found through research that due to Figure 2 shows the Iu control plane interface protocol stack structure in the 3G network, which is similar to Figure 3 shows some differences between the S1 control plane interface protocol stack structures of the LTE / SAE network, among which A main difference lies in the difference of Non Access Stratum (NAS, Non Access Stratum) protocol, the allocation and management mechanism of 3G PDP context-related identifiers, and the allocation and management mechanism of bearer-related identifiers in LTE / SAE are very different. Therefore, there will be certain difficulties in improving the performance of the original 3G network and making the SAE network compatible with the 3G wireless access network

Embodiment Construction

[0037] The embodiment of the present invention provides a unified PDP context and bearer context management method, wireless network controller and system based on the Iu-PS interface of the 3G network to the S1 interface of the LTE / SAE network, for solving the problem of compatibility of the SAE network with the 3G network UTRAN. In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0038] Such as Figure 4 As shown, the control plane protocol stack structure diagram of the RNC providing the S1 interface to the MME for the embodiment of the present invention, the unified PDP context based on the Iu-PS interface of the 3G network to the S1 interface of the LTE / SAE network provided by the embodiment of the present invention and bearer context management methods are based on Figure 4structure shown. The PDP con...

Abstract

The invention discloses a PDP context based on the condition that an Iu-PS interface of a 3G network is unified to an Sl interface of an LTE / SAE network, and a management method for loading the context. The method comprises the steps: establishing a connection relationship of NSAPI, TI and EPS BearerId by a wireless access network controller, informing a mobility management entity of the connection relationship, inducing the Sl interface of the SAE network by UTRAN of the 3G network to further induce a certain characteristic of the SAE network so as to enhance the performance of the original 3G network and enable the SAE network to be compatible with the UTRAN of the 3G network to promote the evolution and the integration of the networks. In addition, the invention also discloses the wireless access network controller and a system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a management method, device and system of a PDP context and bearer context based on an S1 unified interface. Background technique [0002] The development of mobile communication has formed a variety of wireless communication systems, such as the second generation mobile communication system (2G): Global System for Mobile Communication (GSM, Global System for Mobile Communication), General Packet Radio System (GPRS, General Packet Radio System), Enhanced data rate GSM service (EDGE, Enhanced Data rates for GSM service), code division multiple access (CDMA, Code Division Multiple Access); third generation mobile communication system (3G): unified mobile communication system (UMTS, Universal Mobile Telecommunications System, Also known as Wideband Code Division Multiple Access (WCDMA, Wideband CDMA)), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA...
