Description
Technical field
The present invention relates to the communications field, and especially, relate to cross-domain end-to-end (end-to-end) path establishment method in the next generation network (NGN).
Background technology
At present, the mechanism that how to realize end to end network resource allocation and control is one of major issue of network resource admission control in the next generation network.Along with the technical development of NGN network and deployment gradually, it is extremely important that this problem will become.
Lead alliance's next generation network (ITU-NGN) resource allocation and controlled function subsystem (promptly in present international telecommunication, resource accommodating control function (RACF), its structure is as shown in Figure 1) related definition in (mainly being to define in Y.RACF (Y.2111) standard), the mode that transmits the foundation of net domain-across end-to-end path is divided into three kinds, and first kind is to finish by the traffic signaling between the operation layer service control function cell S CF (service control function); Second kind is to finish with the signaling on road by transmitting net itself; The third is to finish (its specific implementation as shown in Figure 2) by the cross-domain interface Ri interface between strategy decisive function unit (PD-FE) entity in the Resource and Admission Control Sub-system that transmits key-course.
Fig. 1 shows the structure according to the RACF of correlation technique.
In structure shown in Figure 1, comprise following functional unit: transmit resource and carry out functional unit (Transport Resource Enforcement Function Entity, TRE-FE), policy enforcement function unit (Policy Enforcement Function Entity, PE-FE), transmit resource control function units (Transport Resource Control Function Entity, TRC-FE), strategy decisive function unit (Policy Decision Function Entity, PD-FE), and resource accommodating control function (Resource Admission ControlFunction, RACF).
The function of each interface between the above-mentioned functions unit is as follows: the Rc interface is responsible for transmitting the network topology of network (Transport Functions) and the collection and the resource operating position in the network operation process of resource information collected feedback;
The Rs interface is responsible for service control layer (SCF) and is carried out the relevant mutual of service conversation abstract resource request with the strategy decisive function unit (PD-FE) that transmits network control preparative layer (RACF);
The Rt interface be responsible for strategy decisive function unit PD-FE with transmit request that net resource control function units (TRC-FE) carries out the session Internet resources and distribution relevant alternately;
The Ri interface is responsible for the cross-domain communication between the PD-FE;
The Rp interface is responsible for the intra-area communication between the TRC-FE;
In ITU-T Y.RACF standard and other relevant criterion, defined the concrete function of each functional unit and interface, will no longer repeat (the Rj interface among Fig. 1 is to set up set interface for the realization session path, and this interface will be explained hereinafter) here.
In above-mentioned three kinds of modes based on this structure, can guarantee the foundation of domain-across end-to-end path fully except that second kind, other two kinds of methods some need with transmit information that network technology is closely related and (for example just can finish under the situation that end-to-end path sets up, use in the network of MPLS-TE technology) can't finish the foundation of end-to-end path, this be because:
PD-FE is a functional unit of being absorbed in the corresponding strategies decision-making of bearer network technology irrelevant (transport technologyindependent), and it is the information relevant with Bearer Network not, therefore can't instruct the foundation in the relevant path of Bearer Network;
And what transmit between the SCF also is professional relevant signaling, does not possess the ability of the foundation in the relevant path of the Bearer Network of instructing.
And in the second approach, transmit the channel associated signalling of net own and set up the problem that there is aspect such as autgmentability again in the mode of domain-across end-to-end path, be unfavorable for widespread deployment.
And, the present effective scheme that does not propose to set up domain-across end-to-end path as yet.
Summary of the invention
Consider the problems referred to above and make the present invention that for this reason, main purpose of the present invention is to provide a kind of domain-across end-to-end path to set up scheme.
According to embodiments of the invention, provide a kind of domain-across end-to-end path establishment method.
This method comprises: step S502, request is set up in the path in this domain policy decision making function unit in the network in this territory of this territory transmission resource control function units transmission session, and, this territory is transmitted resource control function units and is received path computing and the resource allocation of carrying out after the path foundation request in this territory of session in this territory, generates the relevant information that the path is set up in this territory;
Step S504, this territory is transmitted resource control function units and is sent the relevant information that the path is set up in conversation request and this territory by the cross-domain interface between this territory transmission resource control function units and territory, the opposite end transmission resource control function units to territory, opposite end transmission resource control function units, the territory, opposite end is transmitted resource control function units and is received path computing and the resource allocation of carrying out after the relevant information of setting up in cross-domain conversation request and path in the territory, opposite end in, generates the relevant information of path foundation in the territory, opposite end;
Step S506, resource control function units and territory, opposite end are transmitted in this territory, and to transmit resource control function units unidirectional or notify its relevant information of setting up of path in territory, place separately mutually by cross-domain interface, and with the relevant information that the path is set up inform its separately the transmission resource of place realm entry node carry out functional unit; And
Step S508, the transmission resource that the transmission resource in this territory is carried out functional unit and territory, opposite end carry out functional unit respectively to its separately the relevant information set up of the path in territory, place handle, connect and Resources allocation.
Wherein, in step S502, this domain policy decision making function unit end-to-end path in this territory of this territory transmission resource control function units transmission session is set up request.
And the relevant information that the path is set up comprises: Egress node information and packet encapsulation information.
In addition, in the method, above-mentioned cross-domain interface is the Rj interface, and the cross-domain interface transmission information relevant with transmission network.And network is a next generation network.
By technique scheme of the present invention, solved the problem that the domain-across end-to-end path foundation that is closely related with Bearer Network can't be finished in service control function and strategy decisive function unit.
