Problems solved by technology

This method mainly has the following defects: due to the roaming characteristics of mobile users, all networks that support roaming need to maintain the number segment data of IMSI / MSISDN / IPv4 / IPv6, and the data maintenance workload of multiple roaming networks is more than that of this network. In addition, the number segment planning of IMSI / MSISDN / IPv4 / IPv6 will cause waste and shortage of resources
However, 3GPP's "DRA proxy method" has the following defects: it needs to add DRA proxy network elements, which makes the PCC architecture more complicated; DRA needs to maintain user-based binding data, or APN (AccessPointName, access point name)-based binding fixed data
As a result: in multi-PCRF networking, a dedicated DRA proxy network element must be configured; when DRA network elements are deployed in pairs, dynamic binding data synchronization between DRAs, or data sharing through other technologies is required, which is very complicated to implement ;When DRA network elements are deployed in pairs, there are problems with the compatibility of DRA devices from different manufacturers; DRA network elements become a new negative factor affecting services, thereby reducing the reliability of the entire system service
[0009] For the above problems caused by configuring multiple PCRFs to share the load in related technologies, no effective solution has been proposed yet

Embodiment 1

[0150] In this embodiment, the session binding of the Gx / Rx interface when the user terminal initiates a VoIP service is taken as an example for illustration.

[0151] Figure 11 For the signaling flow chart of the session binding of the Gx / Rx interface in this embodiment, such as Figure 11 As shown, it mainly includes the following steps:

[0152] Step S1101: the user initiates a VoIP service, and the terminal sends a PDN connection request message (PDNCONNECTIVITYrequest) message to the MME, carrying the IMSI number and APN information;

[0153] Step S1102: After receiving the message, the MME sends a create session request message (CreateSessionRequest) to the SGW.

[0154] Step S1103: After receiving the message, the SGW sends a create session request message (CreateSessionRequest) to the PGW.

[0155] Step S1104: After receiving the message, the PGW sends a CCR_I (CCRInitial, CCR initial message) message to establish a Gx session according to the user's IMSI / APN and t...

Embodiment 2

[0165] In this embodiment, when a user terminal initiates a data service, a new PDN connection is established with the same APN, and sessions of multiple Gx interfaces are bound to the same PCRF as an example for illustration.

[0166] Figure 12 It is a signaling flowchart of multi-session binding in this embodiment, such as Figure 12 As shown, it mainly includes the following steps:

[0167] Steps S1201-S1208: same as Step S1101-Step S1108 of Embodiment 1;

[0168] Step S809: The user establishes a new PDN connection, the terminal judges that the PDN connection has been established, and the APN is the same, and uses the recorded PCRF information to set the PDN connection request message;

[0169] Step S1210: The terminal sends a PDN connection request message (PDNCONNECTIVITYrequest) message to the MME, carrying the IMSI number, APN information, and PCRF information;

[0170] Step S1211: After receiving the message, the MME sends a create session request message (CreateS...

Abstract

The invention discloses a multi-session binding method, device and system. The method comprises that a user terminal receives PCRF related information which is distributed by a PGW when the user terminal establishes a first IP-CAN session of a Gx interface; and the user terminal sends an invitation message, which carries the PCRF related information, to an AF, and the AF is thus indicated to set PCRF as a target host for authenticating application messages when the user terminal establishes the session of the Rx interface.

Description

technical field [0001] The present invention relates to the communication field, in particular to a multi-session binding method, device and system. Background technique [0002] LTE (that is, 4G) can provide 20M bandwidth for a single mobile user, realizing wireless broadband. In LTE, if you continue to use the fixed rate of traffic (for example, 70M / 10 currency units), because it needs to consume a lot of bandwidth, services that need to consume a lot of bandwidth (such as high-definition video on demand, etc.) are used by users less likely. For operators, they cannot take advantage of the high bandwidth of the 4G network, thus wasting network resources and weakening the competitiveness of the 4G network. For service providers, due to the low utilization rate of users, they cannot obtain sufficient income and reinvestment, which affects the continuous provision of services and makes it difficult for users to enjoy colorful high-bandwidth services. [0003] In the PCC (P...
