Method for cross-domain communication between resource control function units

Abstract

The invention discloses a method of cross-domain communication realization among send data control function unit, which includes: step S402, a cross-domain interface is arranged between a domain send data control function unit and an opposite domain send data control function unit in the network and step S404, the domain send data control function unit and the opposite domain send data control function unit exchange the information related to a transmission network by a cross-domain interface and establish connection relation. The invention complies with the principle of PD-FE irrelevant to the bearing network technology, solves the problem of excessive middle roles played by PD-FE in related technology, improves the communication mechanism of cross domain among send data control function units and improves the communication efficiency and safety.

Description

technical field [0001] The present invention relates to the field of communication, and in particular, to a method for realizing cross-domain communication between Transport Resource Control Function Entities (TRC-FEs) in a Next Generation Network (NGN). Background technique [0002] At present, how to implement an end-to-end (end-to-end) network resource allocation and control mechanism is one of the important issues of network resource admission control in the next generation network. With the technological development and gradual deployment of NGN networks, this issue will become very important. [0003] FIG. 1 shows the structure of a RACF according to the related art. [0004] The structure shown in Figure 1 includes the following functional units: Transport Resource Enforcement Function Entity (TRE-FE), Policy Enforcement Function Entity (PE-FE), Transport Resource Control Function A unit (Transport Resource Control Function Entity, TRC-FE), a policy decision functio...

Problems solved by technology

[0015] In addition, forcibly mixing PD-FE and Ri interfaces in the communication between two TRC-FEs causes many problems, such as overload control, reliable communication and other end-to-end communication control mechanisms cannot be implemented, which is obviously not conducive to TRC -Smooth and efficient communication between FEs;

[0016] Moreover, too many intermediate roles played by functional entities will lead to many problems such as reduced communication efficiency, increased error rate, and reduced security.
