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
The present invention relates to the communications field, and especially, relate in the next generation network (NGN) that (Transport Resource Control FunctionEntity realizes the method for cross-domain communication between TRC-FE) transmitting resource control function units.
Background technology
At present, the mechanism that how to realize end-to-end (end-to-end) Resource Allocation in Networks 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.
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 here.
Based on system shown in Figure 1, the mode that TRC-FE carries out cross-domain communication is as follows: the information that the TRC-FE in this territory sends arrives PD-FE in this territory by the Rt interface, again by the achieve the goal PD-FE in territory of the cross-domain interface Ri interface between the PD-FE, send to purpose TRC-FE via the Rt interface in purpose territory again, promptly, TRC-FE is directly cross-domain communication, but need be by the PD-FE in the territory, place separately.
In the interface that has defined, the Rp interfaces special is used for the intra-area communication between the transmission resource control function units (TRC-FE) in the identical network territory, and set up the immediate neighbor relation that transmits in the territory between the resource control function units by this interface and carry out respective communication, thereby finish border in the network management domain to the border resource allocation and the control of (edge-to-edge can be called end-to-end again); And for the cross-domain communication between the transmission resource control function units (TRC-FE) between the heterogeneous networks territory, do not have the interconnect interface between the definition at present in the standard, communicate indirectly by the cross-domain interface Ri between strategy decisive function unit (PD-FE) but be defined as indirectly.
There is following problem when setting up like this, in cross-domain path:
At first, PD-FE is a functional unit of being absorbed in the corresponding strategies decision-making of transmission network (bearer network) technology irrelevant (transporttechnology independent), TRC-FE then is responsible for the resource allocation of handling transmission network technology relevant (transport technology dependent) and control device specially, if the communication between the cross-domain TRC-FE is undertaken by PD-FE and Ri interface thereof indirectly, mean that then PD-FE need handle the communication of the information relevant with transmission network, this and PD-FE transmit with irrelevant (transporttechnology independent) principle of transmission network technology and disagree;
In addition, by force PD-FE and Ri interface are mixed in two communications between the TRC-FE and cause problems, for example, the mechanism that end-to-end communications such as overload control, reliable communication are controlled can't be implemented etc., this obviously be unfavorable between the TRC-FE communication smooth and easy, efficiently carry out;
And functional entity is played the part of too much middle role will cause problems such as communication efficiency reduction, error rate rising and fail safe reduction.
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 and is transmitting the scheme that realizes cross-domain communication between the resource control function units.
According to embodiments of the invention, provide a kind of and transmitted the method that realizes cross-domain communication between the resource control function units.
This method comprises: this territory is transmitted between resource control function units and territory, the opposite end transmission resource control function units cross-domain interface is set in network; And
This territory is transmitted resource control function units and is transmitted resource control function units by the cross-domain interactive interfacing information relevant with transmission network with the territory, opposite end, and establishes a connection.
Wherein, relevant with transmission network information comprises: label switched path information and seal dress information.And annexation is a neighborhood.
In addition, above-mentioned network is a next generation network.
By technique scheme of the present invention, deferred to the irrelevant principle of PD-FE and Bearer Network, and solved the problem that too much middle role is played the part of in the strategy decisive function unit in the correlation technique, improve the communication mechanism that transmits cross-domain communication between the resource control function units, improved the efficient and the fail safe of communication.
