Embodiment 1

[0096] Such as figure 1As shown, the flow chart of the session establishment method provided by one embodiment of the present invention is applied in a network architecture where the third-party SP and PCRF support the XML protocol, and the method includes:

[0097] Step S101, the Diameter routing agent DRA in the Diameter domain where the UE is located receives the PCRF address query request message or the Rx session establishment request message carrying the identification information of the UE;

[0098] Step S102, the DRA queries the correspondence between the pre-stored identification information and the PCRF address according to the identification information, and obtains the PCRF address corresponding to the identification information; the PCRF address is used by the third-party SP to initiate an Rx session establishment request to the PCRF.

[0099] The identification information in this embodiment of the present invention may include International Mobile Subscriber Id...

Embodiment 2

[0116] Such as figure 2 As shown, it is a flowchart of a session establishment method provided by another embodiment of the present invention, the method includes:

[0117] Step S201, the Diameter domain query function entity receives a PCRF address query request message or an Rx session establishment request message in XML format sent by a third-party SP and carrying UE identification information;

[0118] Step S202, the Diameter domain query function entity instructs the DRA where the UE is located to query the PCRF address according to the received request message; the PCRF address is obtained by the DRA based on the identification information and the corresponding relationship between the stored identification information and the PCRF address, and the PCRF address is used for The third-party SP initiates an Rx session establishment request to the PCRF.

[0119] Wherein, the identification information may include IMSI, MSISDN, IP address, IP+PDN and other forms.

[0120]...

Embodiment 3

[0138] Such as image 3 As shown, it is a flowchart of a session establishment method provided by another embodiment of the present invention. The Diameter domain query function entity in this embodiment is deployed on the DRA where the UE is located. The method specifically includes:

[0139] In step 301, the UE establishes an IP-CAN session.

[0140] The session establishment process specifically includes:

[0141] Step 3011, the UE sends an IP-CAN session establishment request message carrying the identification information of the UE to the PCEF;

[0142] In this embodiment, the identification information is the IP address of the UE; when the IP address is a private network IP address, the identification information also includes the PDN information of the UE; the identification information in this embodiment includes the IP address and PDN information as an example Be explained.

[0143] Step 3012, PCEF receives the IP-CAN session establishment request message, selects ...

Abstract

The invention relates to a conversation setup method, device and system. The conversation setup method is applied to network architecture of a third-party SP (service provider) and PCRF (policy and charging control function) supporting XML (extensive markup language) and includes steps that a DRA (Diameter routing agent) in a Diameter domain where UE (user equipment) is located receives PCRF address query request messages or Rx conversation setup request messages carrying identification information of the UE; the DRA inquires correspondence of prestored identification information and PCRF address according to the identification information to obtain PCRF address corresponding to the identification information; the PCRF address is used for transmitting the Rx conversation setup requests to the PCRF by the third-party SP, and the third-party SP transmits the request messages to indicate the DRA where the UE is located to acquire the PCRF address, so that conversation between the third-party SP and the PCRF is set up, and the RX conversation between the third-party SP and the PCRF is set up when both the third-party SP and PCRF interface support the XML and Rx protocol.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for establishing a session. Background technique [0002] At present, opening a Quality of Service (Quality of Service, Qos) capability to a third-party application provider (Service Provider, SP) is a content that operators focus on researching. Existing standards already support this structure, that is, the third-party SP accesses the Policy and charging control function (Policy and charging control function, PCRF) through the Diameter Rx interface, and transmits Qos parameters, so that the Qos guarantee is triggered by the PCRF. At the same time, because the Diameter protocol does not meet the ease of use in the IT field, a project was established in 3GPP to support the Rx interface based on the XML protocol. [0003] In the current standard, if there are multiple Diameter domains in a public land mobile network (Public Land Mobile Ne...
