Abstract

The invention provides a data service processing method. The method comprises: a data gateway receives a request for creating a data carrying session from a mobility management network element, wherein the data carrying session is activated by user equipment (UE) of a roaming user; the data gateway transmits a query request to a policy control network element in order that the policy control network element queries subscription information of the roaming user, wherein the subscription information is subscription information of a valid local data service of the user; the data gateway receives a querying result from the policy control network element; and the data gateway processes the request for creating the data carrying session according to the querying result.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a data service processing method, a data gateway and a policy control network element. Background technique [0002] With the development of the mobile Internet, people also hope to use data services when traveling in different places and on business trips. At present, roaming data charges are very high, and users generally do not enable data roaming in different places, which makes it difficult for users who have signed up for data roaming to use the data service in the roaming area; When using data services, it is also necessary to return to the local data gateway (to access the network, and generally there will be a delay, which affects the user experience. [0003] In the prior art, the method for solving the above-mentioned problem is that after the user arrives at the roaming place, replace the Subscriber Identity Module (SIM) with the SIM card of the roaming place; or ...
