Data transmission method, system and Femto gateway based on Femto

[0029] Such as image 3 As shown, it is a schematic diagram of a Femto-based data transmission method in Embodiment 1 of the present invention, and the method specifically includes the following steps:

[0030] Step 101: The Femto gateway judges whether the IuH interface connection with the Femto base station is interrupted, if yes, executes step 102; if not, continues to judge whether the IuH interface connection is interrupted.

[0031] Whether the IuH interface connection is interrupted refers to whether the IuH interface between the Femto gateway and the Femto base station is abnormal in control plane signaling and the user plane connection is interrupted.

[0032]In the Femto system, the control plane signaling used to control the establishment, maintenance and release of the call process is transmitted through the IP network with poor quality of service (Quality of Service, QoS), and often the control plane signaling Signaling on the control plane is abnormal due to condit

[0058] Based on the same idea as that of Embodiment 1 of the present invention, Embodiment 2 of the present invention proposes a Femto gateway, and its structural diagram is as follows Figure 4 shown. Described Femto gateway comprises: first judgment module 11, resource cache module 12 and restoration module 13, wherein:

[0059] The first judging module 11 is configured to judge whether the IuH interface connection with the Femto base station is interrupted.

[0060] The resource cache module 12 is configured to cache the user plane resources of the CS domain and the PS domain between the Femto base station and the Femto base station when the first judging module 11 judges that the IuH interface connection is interrupted.

[0061] The recovery module 13 is configured to use the user plane resources cached by the resource cache module to recover data transmission in the CS domain and the PS domain when the Femto base station successfully re-registers locally.

[0071] Such as Figure 5 As shown, the Femto-based data transmission system in Embodiment 3 of the present invention includes: a terminal 31, a Femto base station 32, a Femto gateway 33 and a core network 34, wherein:

[0072] The terminal 31 is used to transmit PS domain / CS domain data through the Femto base station 32 and the Femto gateway 33 and the core network 34 .

[0073]The Femto base station 32 is configured to re-register in the Femto gateway 33 when the IuH interface connection with the Femto gateway 33 is interrupted.

[0074] The Femto gateway 33 is used to judge whether the IuH interface connection with the Femto base station 32 is interrupted, and when it is judged that the IuH interface connection is interrupted, cache the user plane resources of the CS domain and the PS domain between the Femto base station 32, and When the Femto base station 32 successfully re-registers locally, the cached user plane resources are used to resume data transmission in the CS do
