Problems solved by technology

If the network needs to implement policy control, since the existing policy control session is based on IP connection, the existing EPS network data connection-related policy control process is not applicable to the situation where the data channel between the terminal and the data gateway does not establish an IP connection
In addition, for the mobility management protocol between the gateways, the prior art is only applicable to the GPRS Tunneling Protocol (GTP, GPRS Tunneling Protocol) that may not require an IP address, but not to the mobile IP protocol

Embodiment Construction

[0029] Embodiments of the present invention provide a method for establishing a data connection, a mobile network, and a policy control entity. After a data channel is established between a terminal and a gateway, the gateway triggers the policy control entity to establish or update a policy control session. In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0030] As shown in Figure 3, the flow chart of the method for establishing a data connection provided by the embodiment of the present invention includes the following steps:

[0031] Step 301, establishing a data channel between the terminal and the gateway;

[0032] Step 302, the gateway assigns an IP address to the terminal according to the address assignment request message sent by the terminal;

[0033] Step 303, the gateway triggers the policy contr...

Abstract

The invention discloses a method for establishing data connection of a mobile network which includes: establishing a data channel between a terminal and a gateway; establishing a requiring information for distributing IP address to the terminal according with address distributing requiring information sent by the terminal or data channel by the gateway; establishing or updating maneuver control conversation according with IP address trigger maneuver control entity by the gateway. The invention also provides a mobile network and a maneuver control entity that the gateway trigger maneuver control entity can realize establishing or updating of maneuver control conversation after the data channel is established between the terminal and the gateway.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for establishing a data connection of a mobile network, a mobile network and a policy control entity. Background technique [0002] As shown in Figure 1, the network architecture supporting service-level dynamic policy control is proposed for the next generation mobile communication network. In the Evolved Packet Communication System (EPS, Evolved Packet System) network, the user mobile terminal accesses the Evolved Packet Core Network (EPC, Evolved Packet Core) through the service gateway in the wireless access network; accesses the external data network through the data gateway. According to the business information of the terminal, the policy control entity can dynamically generate policy rules for business data and issue them to the data gateway and service gateway, thereby completing the business-level dynamic policy control of data. [0003] As shown in Fig...
