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

Embodiment 1

[0029] A kind of data transmission method of Femto base station, as figure 2 shown, including the following steps:

[0030] Step S1, after the Femto base station is started, use specific means (such as ping command, etc.) to regularly monitor the network status of the Internet public network, and regularly send the monitored results. The network status represents the quality and performance of the current network, such as maximum delay, average delay, packet loss rate, survival time, etc.

[0031] Step S2, the user (UE) interacts with the core network for service signaling. The specific process is: when the user initiates a service and communicates with the Femto base station, the signaling is processed by L1, L2 and other related signaling processing units, and establishes with the core network. The connection of the radio bearer and the Iu connection, and complete the interaction of related direct transmission signaling defined by 3GPP. The above-mentioned L1 refers to th...

Embodiment 2

[0048] Corresponding to the data transmission method of a Femto base station in Embodiment 1, the present invention also provides a data transmission device for a Femto base station, such as image 3 shown, including

[0049] The public network network monitoring module is used to regularly monitor the network status of the public network after the start of the Femto base station, and regularly send the monitored network status of the public network to the data transmission channel selection module;

[0050] The signaling processing module is used to process all service signaling between the user and the core network specified by 3GPP. When the core network sends the corresponding signaling to the Femto base station through the gateway to establish the service, extract the parameters of the service in the corresponding signaling and submit it to Wireless resource management module;

[0051] A wireless resource management module connected to the signaling processing module, co...

Embodiment 3

[0057] When the data is switched to be transmitted from the public network, there is no data transmission on the link with the core network, and if the core network fails to detect data within a certain period of time, the connection with the user may be disconnected. Therefore, it is necessary to maintain the link between the user and the core network in order to continuously drop the connection and provide a data path for re-switching back. As a better embodiment, the present invention adopts the method of regularly sending a very small amount of data and indirectly transmitting it to the core network to maintain the link, that is, after extracting the packet domain data and directly transmitting the packet domain data to the public network, According to the user information, the link between the user and the core network is maintained. For this reason, the data transmission device of the Femto base station of the present invention includes all modules in the second embodimen...

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.
