AI Technical Summary

Problems solved by technology

[0004] Because the reset detection mechanism may not be timely, the downlink data of some UEs is unreachable
In the actual network, the service gateway and the data gateway are often deployed together. When the service gateway or the data gateway is reset, the other gateway is also reset. Therefore, the above method cannot realize the reconstruction of the network connection when the service gateway and the data gateway are deployed together.

Embodiment Construction

[0099] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0100] Such as figure 1 It is a logical architecture diagram of the EPS mobile communication network, and the UE accesses the mobile communication network through the local wireless access network. The access node is the convergence point of the access network, responsible for the location management, connection management, security authentication, gateway selection and other functions of the mobile user equipment. The service gateway is the local access gateway of...

Abstract

The embodiment of the present invention discloses a method for reestablishing a network connection, including: detecting whether a gateway reset occurs, and if it is detected that a gateway reset occurs, when receiving a downlink data packet sent by the packet data network, sending the network connection to the access node In the reestablishment trigger message, the access node reestablishes the network connection corresponding to the downlink data packet according to the type of gateway reset, wherein the type of gateway reset is data gateway reset or service gateway reset. The present invention can quickly rebuild the network connection, and can be applied to the situation where the service gateway and the data gateway are deployed together.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network connection reconstruction method, related equipment and a system. Background technique [0002] In the logical architecture system of the enhanced packet switching (Enhanced Packet Switch, EPS) mobile communication network, the user equipment (User Equipment, UE) accesses the mobile communication network through the wireless access network, and the access node is the convergence of the wireless access network point, the service gateway is the local access gateway of the UE, and the data gateway is the gateway for the UE to access the external data network. After network nodes such as access nodes, service gateways, or data gateways are reset, user information on the reset network nodes, such as user context, packet data protocol (Packet Data Protocol, PDP) context, packet data network (Packet Data Network, PDN) connection Information such as context is lost. If the n...
