Embodiment Construction

[0060] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. 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.

[0061] In the prior art, a UE may be connected to multiple different Packet Data Network Gateways (PGW for short) through a TWAN to access multiple corresponding PDNs. It is equivalent to that the UE is connected to multiple different local area networks at the same time, and the multiple local area networks are independent of each other. The UE ...

Abstract

The embodiment of the invention provides a connection releasing method and a device for a packet data network. The method comprises that: a releasing message sent by user equipment UE is received, and the releasing message comprises an indication identifier; and according to an association relation between the indication identifier and a connection identifier, connection corresponding to the connection identifier associated with the indication identifier is released. According to the connection releasing method and the device for the PDN, the corresponding connection identifier of the connection needed to be released is learnt in a way that the indication identifier associated with the connection identifier is carried in the releasing message according to the association relation between the indication identifier and the connection identifier.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a method and device for releasing a packet data network (Packet Data Network, PDN for short) connection. Background technique [0002] User Equipment (UE) can access the Evolved Packet Core in the Evolved Packet System (EPS) through a Trusted Wireless Local Area Networks Access Network (TWAN) Network (Evolved Packet Core, referred to as EPC). [0003] In the prior art, when the UE accesses the EPC through the TWAN, multiple PDN connections corresponding to the same access point name (Access Point Name, APN for short) may be established, or multiple PDN connections corresponding to different APNs may be established. When the UE does not need to transmit data through a certain PDN connection, the UE may release the PDN connection. [0004] However, in the prior art, there is often a problem that the PDN connection cannot be released conveniently and correct...
