Abstract

The invention discloses a method, a device and a system for connecting a packet data network. The method comprises the following steps that: an evolved node B selects one gateway from at least two gateways, wherein the at least two gateways at least comprise a first gateway and a second gateway, the first gateway is connected between the evolved node B and a core network and connected with the packet data network through the core network, and the second gateway is connected between the evolved node B and the packet data network and directly connected with the packet data network; and the evolved node B connects user equipment to the packet data network through the selected gateway. Through adoption of the method, the device and the system, the problem of overload on the core network due to the way for the user equipment to access to the packet data network in a conventional mobile communication system is solved.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to a method, device and system for connecting packet data networks. Background technique [0002] In a traditional mobile communication system, the user equipment is connected to the core network through the base station and connected to the PDN, thereby establishing a connection between the user equipment and the PDN, and the user equipment can access the PDN, and the core network can exchange control signaling and communication with the UE. Data information, so as to provide the connection between the UE and the PDN, provide good mobility management, charge the communication services of the UE, and so on. For some special deployment scenarios, a gateway needs to be added between the base station and the core network, such as figure 1 As shown, for example, this solution is usually adopted in the deployment of home base stations HeNB in ​​homes, which can avoid problems cause...
