Description
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.
