Problems solved by technology

However, the handover based on this converged architecture does not consider the service characteristics, which may lead to discontinuity or poor performance of the service after the handover. At the same time, this patent only considers the handover that occurs during the communication process, and does not offload the access network from the source. flow

Embodiment 1

[0023] Example 1 combined Figure 1~3 Describe the EPS-WLAN fusion system of the present invention

[0024] The present invention provides a fusion system of Evolved Packet System EPS and WLAN, such as figure 1 shown. The system includes a mobility management entity MME, a data gateway P-GW, a WLAN access gateway WAG and various wireless access points AP. Such as figure 2 As shown, the WAG is connected to the MME and the P-GW through the S1-WM and S5-WP interfaces respectively. When a user accesses the EPS system service through the WLAN network, the AP communicates with the WAG through the WLAN protocol, that is, 802.11, and the WAG and the MME communicate through the 802.3 protocol. At the same time, it is necessary to expand the processing capability of the MME for Ethernet data; if the WAG and Authentication and authentication messages are transmitted between MMEs. They communicate through Radius, and MME extracts relevant data from the home subscriber server HSS thr...

Embodiment 2

[0027] Example 2 combined Figure 4 and Figure 5 Further illustrate the process of switching from the EPS system to the WLAN system of the present invention

[0028] Based on the above converged system, when the dual-mode terminal switches from the EPS system to the WLAN system, the switching is based on the service identifier and occurs when the service is requested. specific process such as Figure 5 As shown, the transfer process identified in the switching process is as follows Figure 4 As shown, the specific steps are as follows:

[0029] 1) The current service network of the user terminal is EPS, which sends a service request to the eNodeB, and the request message contains the following fields: TMSI, user terminal IP Address1 (the IP address assigned by the P-GW to the terminal when the user terminal is attached to the EPS system ) and a service identifier, wherein the user terminal IP Address1 is the IP address assigned by the P-GW to the terminal when the user te...

Abstract

The invention discloses an EPS (Electronic Power Steering)-WLAN (Wireless Local Area Network) fusion system and a switching method based on a framework, and relates to the technical field of communication and a WLAN. The EPS-WLAN fusion system comprises a mobility management entity MME, a data gateway P-GW, a WLAN access gateway WAG and each wireless access point AP, wherein the gateway WAG is respectively connected with the mobility management entity MME and the data gateway P-GW through an S1-WM interface and an S5-WP interface. In the fusion system, when a dual-mode terminal is switched into the WLAN from an EPS system, the switching is based on business identification and occurs during service request. According to the fusion system and the switching method, an M2M business is switched into the WLAN, and therefore the load pressure of the EPS system access network is relieved, so that a system resource is more reasonably utilized, and the system performance is ensured.

Description

technical field [0001] The invention mainly relates to the technical field of mobile communication and wireless local area network. Specifically, it relates to a system for integrating LTE and WLAN networks and an M2M service-based handover method that occurs when a service is requested. Background technique [0002] M2M is the abbreviation of Machine-to-Machine. It refers to the general term of a series of technologies and their combinations that apply communication technology to realize data communication and exchange between people and people, between people and machines, and between machines. Information exchange and communication types. It covers all achievable technologies and means for information transmission and exchange between people, machines, and systems, that is, the Internet of Things in a broad sense, which will be widely used in various industries and people's daily life in the future. Hundreds of millions of non-IT devices are about to be added. [0003]...
