Embodiment Construction

[0036] Firstly, several embodiments of the present invention will be described as a whole.

[0037] An embodiment of a method for processing downlink user data in the present invention includes: the S-GW receives downlink user data; if there is a user plane bearer in the evolved network, sending the user data to the user equipment through the evolved network; otherwise, sending the user data to the 2G / 3G network for processing, so as to send the user data to the user equipment through the 2G / 3G network or the evolved network, wherein the user equipment has been in the evolved network and the evolved network Register on the 2G / 3G network mentioned above.

[0038] If there is a user plane bearer in the evolved network and the user plane bearer includes a user plane bearer corresponding to the user data, the user data may be sent to the user equipment through the evolved network according to the following steps: The user data is sent to the eNodeB through the corresponding user ...

Abstract

The invention provides a downstream user data processing method, which comprises an S-GW used for receiving downstream user data; the user data is transmitted to a user device by the evolution network if an evolution network has a user plane loading,, otherwise the user data is transmitted to a 2G / 3G network for processing, thereby transmitting the user data to user equipment by the 2G / 3G network or the evolution network, wherein the user equipment is registered in the evolution network or the 2G / 3G network. In the invention, if the evolution network has no user plane loading, the user data can be transmitted to the 2G / 3G network for processing, under the circumstance of transmitting the user data to the 2G / 3G network for processing, even if the network side does not understand the present status of the user equipment, the user data can still be transmitted to the user equipment through the sequent processing of the 2G / 3G network.

Description

technical field [0001] The present invention relates to communication technology, in particular to downlink data processing technology. Background technique [0002] Currently, Long Term Evolved (LTE, Long Term Evolved) / System Architecture Evolved (SAE, System Architecture Evolved) is a hot technology, and with the continuous improvement and establishment of 2G / 3G networks, LTE / SAE may merge with 2G / 3G network coexistence operation. But there will be a problem in this way, that is, user equipment (UE, User Equipment), especially mobile terminals, will inevitably move between two networks sometimes, or in other words, user equipment may move from one network to another network, if When the user equipment moves to a new network, it needs to initiate the registration process with the new network. If the user equipment frequently moves between the two networks, it will frequently initiate the registration process, which will bring a lot of signaling overhead. This results in ...
