Data transmission method and data transmission device of Femto station, and Femto station

Abstract

The invention provides a data transmission method and a data transmission device of a Femto station, and the Femto station. The method includes that after the Femto station is started, a network state of a public network is monitored at regular time; when service signaling interaction is conducted between a user and a core network, the Femto station receives corresponding signaling sent by the core network through a gateway, and parameters of service of the corresponding signaling are extracted; quality of service (QoS) required by packet domain service is calculated according to the parameters of the service; the QoS required by the packet domain service, and the network state of the public network monitored at regular time are calculated in a compared mode, and whether the network of the current public network satisfies the QoS required by the packet domain service is judged; if yes, packet domain data are extracted and are directly transmitted to the public network; and if not, circuit domain data or the packet domain data are packaged and are transmitted to the core network through the gateway. The data transmission method and the data transmission device can relieve pressure of processing of the packet domain data of the core network, and reduces data traffic tariff of the user.

Description

technical field [0001] The present invention relates to the technical field of wireless network communication, in particular to a data transmission method of a Femto base station, a data transmission device of a Femto base station and a Femto base station. Background technique [0002] In order to solve the problem of insufficient indoor coverage and increase coverage capacity of wireless communication systems, especially in the construction of 3G, to provide high-speed and reliable voice and data services for indoor coverage, a home base station or enterprise base station for home and enterprise environments emerged as the times require . This type of base station is based on the IP architecture and relies on existing broadband means such as DSL (Digital Subscriber Line), cable (cable) or optical fiber to access the network of mobile operators. Such as figure 1 Shown is the network transmission topology diagram of the existing Femto base station. After receiving the servi...

AI Technical Summary

Problems solved by technology

[0004] 1. There are a large number of Femto base stations. Sending all packet domain data to the core network unconditionally through the gateway will cause a core network (such as the GPRS service support node SGSN and the gateway GPRS support node GGSN in the 3G core network). To process a large amount of data, this will inevitably increase the load on the core network, and even cause data congestion, consuming a lot of energy

In order to alleviate this situation, operators will inevitably expand the core network, resulting in high cost investment;

[0005] 2. All packet domain data is sent to the core network through the gateway. In the traffic-based billing mode, it will bring high traffic charges to users, which will inevitably limit the user's experience of 3G services, and is not conducive to 3G networks and Competition for WIFI networks
