Description

Method and device for acquiring routing information, routing addressing device and system

Technical field

The present invention relates to the field of communications, and in particular, to a method and apparatus for acquiring routing information, a routing addressing device, and a system.

Background technique

In recent years, in order to obtain a better market competitive position and provide a better user experience, mobile operators are still under pressure when they are not as profitable as before, and continue to invest heavily in mobile communication network infrastructure construction. At the same time, with the rapid development of mobile networks and the popularity of smart terminals, mobile Internet services, especially video services and social services, have been prosperous and prosperous. Users' habits of using mobile networks are traditional voice and SMS services. Gradually shifting to data services based on mobile Internet content and OTT (Over The Top), users' consumption is also mainly from the consumption of voice and short message services to the consumption of mobile data traffic, and the consumption of data traffic continues to be high. increase.

However, operators have not obtained higher Average Revenue Per User (ARPU) values from the surge in traffic demand and the simultaneous increase in mobile subscribers, but rather because of continued investment in supporting traffic consumption and voice services. The loss of the message business has made operators' operations increasingly difficult. In this context, the operator introduces a policy that mainly includes a Policy and Charging Rule Function (PCRF) and a Policy and Charging Enforcement Function (PCEF). The Policy and Charging Control (PCC) system is used to construct intelligent pipelines. It is hoped that through the insight of each bit of data traffic flowing through the carrier network, differentiated QoS and charging control are implemented, and corresponding operational means are implemented. Increase the added value of data traffic, improve the income level, and better serve mobile terminal users.

In the planning and construction process of the PCC system, with the increase of service capacity, a set of PCRF and PCEF can no longer support the business needs, and gradually need to build multiple sets of PCRF and PCEF. When multiple sets of PCRF exist, the routing of PCRF becomes a problem, and the current industry solutions There are two types, one is to introduce a Diameter Routing Agent (Diameter, abbreviated as DRA) device defined by the 3rd Generation Partnership Project (3GPP), and PCRF routing is performed by DRA. The scheme of the address, which requires the construction cost and operation and maintenance cost for the DRA equipment because of the introduction of the new DRA network element; the other is the PCEF and the service system (the 3GPP's Policy and charging control architecture specification 3GPP) The AF in the TS 23.203, the full name of the Application Function, all of which uses the AF to refer to the service system, adds a static routing table, and the static routing table stores the correspondence between the PCRF and the terminal device identifier. In this solution, both the PCEF and the service system side need to maintain a static routing table, and the two static routing tables should be modified according to the changes of the PCRF and the terminal device at any time, which increases the maintenance workload and develops corresponding software logic. Corresponding processing, especially for a network element defined by the 3GPP standard such as PCEF, this software logic is not supported by the standard specification, and it is difficult to get commercial promotion.

In view of the above problems in the related art, there is currently no effective solution.

Example 5

This embodiment provides a route addressing method. The method in this embodiment does not rely on DRA for routing addressing in the case of multiple PCRFs, and avoids custom development of PCEF and AF in the case of multiple PCRFs, thereby solving the multi-PCRF situation. The PCRF routing problem under the route.

In this embodiment, by establishing a signaling link with all PCRFs in the network and maintaining a signaling link, the Diameter protocol is used to interface with the PCRF and perform message interaction according to the Rx interface specification supported by the PCRF, and the PCRF device is provided. Performing message interaction, and accepting Diameter response signaling messages returned by each PCRF device at the same time or sequentially. In the return message, by determining the return code of each message, a successful response message is determined, and each message can be sorted out. The PCRF to which the Rx session newly initiated by the AF belongs, extracts the PCRF routing information such as the PCRF address or the host name from the response signaling message, and completes the routing addressing of the PCRF.

Based on this, the device for directly addressing the PCRF broadcast message in the embodiment includes: a link management module, a link connection module, a signaling broadcast module, and a route addressing module, where

The link management module provides configuration management and maintenance functions for the Diameter signaling link. The link management module adds the Diameter signaling link information according to the PCRF device existing in the network, and the new link command is sent to the link connection module; the link management module modifies the change according to the PCRF device in the network. The Diameter signaling link information, and the modified link command is sent to the link connection module; the link management module deletes the Diameter signaling link information according to the change of the PCRF device in the network, and releases the link command to the link chain. Road connection module. When the link management module receives the link abnormality between the link and the PCRF, the link management module determines whether the PCRF supports the primary and backup links, and the link connection module and the PCRF exist for the primary and backup devices. On the link, the command is sent to notify the link connection module and the PCRF to perform the primary and backup link switching.

The link connection module receives the link management command of the link management module, performs a Diameter signaling link connection with the multiple PCRFs, and receives a switching instruction of the primary and backup Diameter signaling links of the link management module to implement Switching between links. Specifically, when the link management mode is received The new link command sent by the block, the link connection module establishes a Diameter signaling link with the corresponding PCRF according to the content of the instruction; when receiving the modified link command sent by the link management module, the link connection module follows the instruction content. Finding the existing link and modifying the Diameter signaling link with the corresponding PCRF; when receiving the delete link command sent by the link management module, the link connection module finds the existing link according to the content of the instruction, And deleting the Diameter signaling link with the corresponding PCRF; at the same time, the link connection module monitors the health status of each Diameter signaling link established with the PCRF device to ensure that the abnormal link is detected in time. When an abnormal link is found, a link exception message is reported to the link management module. When the link connection module receives the link management module to issue a link switching instruction, according to the content of the instruction, the connection of the primary link or the working link is interrupted, and the standby Diameter signaling link corresponding to the PCRF is switched to complete the chain with the PCRF. Road switching ensures high link availability with the PCRF.

The signaling broadcast module receives the AF-initiated dynamic policy and the charging request signaling message, and is responsible for broadcasting the Diameter signaling to each PCRF through the link connection module in a parallel manner. The signaling broadcast module performs signaling message encapsulation group packets through the Rx interface specification followed by the PCRF, and advertises Diameter broadcast signaling, and performs signaling interaction between the link connection module and the PCRF. And the link connection module returns the Diameter signaling that receives the PCRF response to the signaling broadcast module. After receiving the Diameter signaling from the link connection module, the signaling broadcast module forwards the Diameter signaling to the route addressing module, and the route addressing module performs route addressing analysis, waiting for the route addressing result of the route addressing module. After receiving the PCRF route addressing result of the route addressing module, the signaling broadcast module terminates to continue to broadcast the dynamic policy and charging request signaling message of the uncompleted broadcast in the new session to the link connection module. At the same time, the link connection module is notified of the PCRF route addressing result, and then the signaling broadcast module extracts routing information such as the address or host name of the PCRF in the route addressing result message returned by the routing addressing module, and the routing information is obtained. The AF is returned along with the dynamic policy and the charging response signaling message.
