<p>A method, device and system of connection re-establishment are disclosed in the invention. The method includes that: a mobility management network element receives a connection message including a user identifier transmitted by a Home Subscriber Server (HSS), wherein the connection message is transmitted by a data gateway to the HSS according to the user identifier after this data gateway or a serving gateway connected with this data gateway is reset; the mobility management network element re-establishes the connection according to the connection message. In the connection re-establishment method of the embodiment of the invention, when the data gateway is reset or the serving gateway connected with the data gateway is reset, the connection message including the user identifier is transmitted to the HSS, and is transmitted to the mobility management network element by the HSS, so the mobility management network element can perform connection re-establishment according to the connection message, and the problem that only after waiting for a period can the mobility management network element acquire that the gateway is reset, and perform connection re-establishment in the prior art is avoided, therefore, the time of the connection re-establishment is shortened greatly, the normal transmission of data is insured, and the user experience is improved.</p> |
