Description

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

Technical Field

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

Background

In recent years, mobile operators have continued to invest heavily in the infrastructure of mobile communication networks, still bearing pressure, in situations where profitability is not as good as before, in order to achieve better market competition and to provide a better user experience. Meanwhile, with The help of The popularization of mobile networks and intelligent terminals developed by operators at a high speed, mobile internet services, particularly video services and social services are prosperous and developed, The use habits of users on The mobile networks are gradually transferred from traditional voice and short message services to data services mainly based on mobile internet contents and ott (over The top), The consumption of The users is also inclined from The consumption of The voice and short message services to The consumption of mobile data traffic, and The consumption of The data traffic is continuously and rapidly increased.

However, operators do not get higher Average Revenue Per User (ARPU) values from the rapidly increasing traffic demand and the simultaneously increasing mobile subscriber volume, but rather make the operators increasingly difficult to operate because of the continuous investment in supporting traffic consumption and the loss of voice traffic and message traffic. Under the background, an operator introduces a Policy and Charging Control (PCC) system mainly comprising a Policy and Charging Rule Function (PCRF) and a Policy and Charging implementation unit (PCEF), constructs an intelligent pipeline, and hopefully, by observing each bit data flow flowing through the operator network, implements differentiated QoS and Charging Control, increases the additional value of the data flow through a corresponding operation means, improves the profit level, and can better serve a mobile terminal user.

In the planning and construction process of the PCC system, along with the increase of service capacity, one set of PCRF and PCEF cannot support service requirements, and a plurality of sets of PCRF and PCEF are gradually required to be constructed. When there are multiple sets of PCRF, the routing addressing of PCRF becomes a problem, and there are two solutions in the industry at present, one is a scheme of using a signaling routing agent (Diameter routing agent, Diameter, abbreviated as DRA) device defined by introducing a third generation Partnership Project (3 GPP), and performing PCRF routing addressing by DRA, and the scheme needs to invest construction cost and operation and maintenance cost for DRA device because a new DRA network element is introduced; the other is that a static routing table is added at the same time to the PCEF and the service system (the service system is the AF in Policy and charging control architecture specification 3GPP TS 23.203 of 3GPP, hereinafter all refer to as the service system), and the static routing table stores the corresponding relationship between the PCRF and the terminal device identifier. The scheme requires that both the PCEF and the service system side need to specially maintain the static routing tables, and the two static routing tables need to be modified at any time according to the change of the PCRF and the terminal equipment, so that the maintenance workload is increased, and corresponding software logic needs to be developed to perform corresponding processing, particularly for a network element defined by a 3GPP standard such as the PCEF, the software logic is not supported by the standard specification, and the commercial landing popularization is difficult to obtain.

In view of the above problems in the related art, no effective solution exists at present.

Example 5

The embodiment provides a routing addressing method, which does not depend on DRA to carry out routing addressing under the condition of multiple PCRFs, and avoids the customized development of PCEF and AF under the condition of multiple PCRFs, thereby solving the routing addressing problem of PCRFs under the condition of multiple PCRFs.

In the embodiment, signaling links are established and maintained with all PCRFs in a network, a Diameter protocol is adopted, the PCRFs are in butt joint with each other according to Rx interface specifications supported by the PCRFs and carry out message interaction, the method has the function of carrying out message interaction with a plurality of PCRF devices, and can accept Diameter response signaling messages returned by the PCRFs simultaneously or successively, in the returned messages, successful response messages are determined by judging the return code of each message, the PCRFs to which Rx sessions newly initiated from AF belong can be sorted out, PCRF routing information such as PCRF addresses or host names is extracted from the response signaling messages, and the routing addressing of the PCRFs is completed.

Based on this, in this embodiment, a device for directly connecting to PCRF broadcast message addressing is further provided, and includes: a link management module, a link connection module, a signaling broadcast module and a routing addressing module, wherein,

and the link management module provides a configuration management maintenance function of the Diameter signaling link. The link management module adds Diameter signaling link information according to the condition of PCRF equipment in the network and sends an instruction of adding a link to the link connection module; the link management module modifies Diameter signaling link information according to the change condition of PCRF equipment in the network and transmits a link modification instruction to the link connection module; the link management module deletes Diameter signaling link information according to the change condition of PCRF equipment in the network, and sends a link deletion instruction to the link connection module. When the link management module receives the link abnormality reported by the link connection module and between the link management module and a certain PCRF, the link management module judges whether the PCRF supports the main link and the standby link, and if the main link and the standby link exist between the link connection module and the PCRF, an instruction is given to inform the link connection module to switch the main link and the standby link with the PCRF.

The link connection module receives the link management instruction of the link management module and executes Diameter signaling link connection between the plurality of PCRFs; receiving the switching instruction of the main and standby Diameter signaling links of the link management module, and realizing the switching between the links. Specifically, when receiving a new link instruction sent by the link management module, the link connection module establishes a Diameter signaling link with the corresponding PCRF according to the instruction content; when receiving a link modification instruction sent by a link management module, the link connection module finds an existing link according to the instruction content and modifies a Diameter signaling link corresponding to the PCRF; when receiving a link deletion instruction sent by a link management module, the link connection module finds an existing link according to the instruction content and deletes a Diameter signaling link corresponding to the PCRF; meanwhile, the link connection module monitors the health state of each Diameter signaling link established between the link connection module and the PCRF equipment, and ensures that abnormal links are found in time. And when the abnormal link is found, reporting a link abnormal message to the link management module. When the link connection module receives a link switching instruction issued by the link management module, the connection of the main link or the working link is interrupted according to the instruction content, and the standby Diameter signaling link corresponding to the PCRF is switched, so that the link switching with the PCRF is completed, and the high availability of the link with the PCRF is ensured.

And the signaling broadcast module receives the dynamic policy and charging request signaling message initiated by the AF and is responsible for broadcasting the Diameter signaling to each PCRF through the link connection module in a parallel mode. The signaling broadcast module packages and packages the signaling message through an Rx interface specification followed by the PCRF, issues the Diameter broadcast signaling, and interacts the signaling with the PCRF through the link connection module. And the link connection module returns the Diameter signaling which receives the response of the PCRF 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 routing and addressing module, so that the routing and addressing module performs routing and addressing analysis and waits for a routing and addressing result of the routing and addressing module.
