Problems solved by technology
That is, although the UE moves from Area1 to Area2, the GGSN is still anchored in Area 1
[0007] For example, for VoLTE voice services, the SIP signaling flow and voice flow are as follows: Figure 1a As shown by the second dotted line in , there is a detour between the SIP signaling flow and the voice flow, and the same is true for the VoHSPA service, which affects the user's voice service experience
[0008] On the other hand, when user equipment roams between different Public Land Mobile Networks (PLMNs), voice services are still performed through the anchor gateway of the original PLMN, and different operators generally cannot communicate with each other, and the user If the device cannot perform voice services smoothly, it will also affect the user's voice service experience

A device, device and method for establishing a connection with a packet data network. The device includes: a first judging unit, configured to judge whether the area served by the anchor gateway that the user equipment is connected to the packet data network is consistent with the area served by the data forwarding gateway when a change in the location of the user equipment is detected; The sending unit is configured to send a packet data network connection release request carrying a reconnection indication to the user equipment when the result of the judgment is negative; the receiving unit is configured to receive the packet data network reconnection request sent by the user equipment; the selection unit, It is used to select an anchor gateway consistent with the area served by the data forwarding gateway; the connection unit is used to connect the user equipment to the packet data network through the selected anchor gateway. The invention also discloses corresponding equipment and methods. By adopting the technical solution of the device, equipment and method for establishing a connection with a packet data network of the present invention, the user's voice service experience can be improved.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to a device, equipment and method for establishing a connection with a packet data network. Background technique [0002] When the user equipment (User Equipment, UE) is performing Voice over Internet Protocol (Voice over Internet Protocol) on the Packet Switch (PS) domain of the System Architecture Evolution (SAE) / Long Term Evolution (LTE) network, VOIP) service, an LTE voice service based on an IP Multimedia System (IP Multimedia Subsystem, IMS) network is called a VoLTE service. This service has an independent access point (Access Point Name, APN), and the UE will create a corresponding packet data network (Packet DataNetwork, PDN) connection. The default bearer is QCI 5, which is used to bear the Session Initiation Protocol (Session InitiationProtocol, SIP) signaling, when the UE has voice services, the policy control and charging (Policy Control and Charging, PCC...
