Embodiment Construction

[0033] In this embodiment, a method for establishing a cross-domain end-to-end path is provided, and the method is a core technology for collecting network topology resources in the next generation network. Among them, the method implements cross-domain communication between transmission resource control functional units (TRC-FE) in the NGN network to realize the method of establishing a cross-domain end-to-end path related to bearer network technology, and realizes cross-domain communication related to bearer network technology. The establishment of the end-to-end path solves the problem in related technologies that the cross-domain end-to-end path establishment cannot be completed due to the need to use bearer network technology-related information. Embodiments of the present invention will be described in detail below.

[0034] As shown in FIG. 3 , in this method, the establishment of the cross-domain end-to-end path in the next generation network is implemented through the...

Abstract

The invention discloses a method of cross-domain end-to-end route establishment. A cross-domain interface is equipped between a domain delivery resources control function unit and an opposite end domain delivery resources control function unit. A cross-domain end-to-end route is established by the domain delivery resources control function unit and the opposite end domain delivery resources control function unit by the cross-domain interface, wherein, the cross-domain interface transmits the information relevant to transmission network. The invention can solve the problem of the cross-domain end-to-end route establishment closely relevant to bearing network technology which can not be finished by the business control function and the decision-making function unit.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a cross-domain end-to-end path establishment method in Next Generation Networks (NGN). Background technique [0002] At present, how to realize the 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] In the relevant definition of the current ITU-NGN resource allocation and control function subsystem (namely, resource admission control function (RACF), its structure is shown in Figure 1) (mainly Y. RACF (defined in the Y.2111 standard), there are three ways to establish cross-domain end-to-end paths on the transport network. The first is through the service information between the service control function units SCF (service control function)...
