Report method in the network between the reciprocity Resource and Admission Control Sub-system entity
Technical field
The present invention relates to network communications technology field, relate in particular to the report method between the reciprocity Resource and Admission Control Sub-system entity in a kind of network.
Background technology
Continuous increase along with the Internet network size, various network services are fallen over each other to emerge in large numbers, various advanced persons' multimedia system emerges in an endless stream, thereby causes Internet network needs often to send sudden high FTP (file transfer protocol (FTP)) or contain the HTTP multimedia services such as (HTML (Hypertext Markup Language)) of image file.For the real time business in the network, because characteristics such as its propagation delay time to network, delay jitter are comparatively responsive, therefore, network is when transmission FTP or HTTP etc. are professional, and is bigger to the influence of real time business.And multimedia service a large amount of network bandwidth that also accounted for makes the key business that needs in the existing network to guarantee bandwidth be difficult to be transmitted reliably.
Be the described real time business that guarantees to transmit in the network and QoS (service quality) problem of key business, ITU (International Telecommunications Union) has proposed the functional mode of an IP signaling demand, as shown in Figure 1, described functional mode mainly comprises: SCFE (interactive function entity), BCFE (entity of carrying control function), SFE (function of exchange entity), CCI (connection control interface), NCI (network control interface) and SCI (exchange control interface).
To be described each functions entity effect among Fig. 1 respectively below.
(1) SCFE: the terminal use is by applying for service alternately with SCFE;
SCFE initiates the QoS request, is determined the parameter of communicate configuration usually by SCFE, as bandwidth, and parameter informations such as QoS; If one group of acceptable parameter can be discussed and decided, the service that SCFE will use BCFE to provide is set up, safeguarded and disconnects Internet resources provides agreed configuration, i.e. negotiatedarrangement (consulting configuration).
(2) BCFE: be responsible for foundation, modification and releasing network resources agreed configuration is provided;
BCFE asks from the QoS that SCFE receives based on Business Stream, and through after the path analysis, BCFE sends to SFE with the path analysis result;
Depend on selected QoS control model, in order to analyze the QoS request and to generate the QoS configuration data, BCFE need know certain network topological information and resource state information.
(3) SFE: be used for and be based upon the virtual connections and the virtual connections interconnection that is based upon the another one port of a port;
One or more such interconnection by on each SFE between the user finally generates the virtual connections between the user; The characteristic of virtual connections based on the calling parameter of SCFE consultation, its route is then determined by BCFE; SFE by BCFE control generates according to the instruction of receiving on the SCI interface or the release interconnection.
(4) CCI:CCI is the interface between the carrying control plane of call/session layer and transport layer.
(5) NCI:NCI is the interface between BCFE and the BCFE.
(6) SCI:SCI is the interface between transport layer carrying control plane and the transport plane.
At present, at IP signaling functional mode shown in Figure 1, only defined the function of above-mentioned function corresponding entity, and between undefined each functional entity in concrete application process concrete loaded information content in needed interaction flow and interaction message each other and each information.Therefore, adopt the model shown in Fig. 1 if desired in actual applications, also needing to define needs loaded information and corresponding service processing process in interactive messages, the message between institute's functional entity, or the like.
In the prior art, the information reporting mechanism that does not also have the agreement between reciprocity RACS (Resource and Admission Control Sub-system) entity (being reciprocity BCFE entity).
Summary of the invention
In view of above-mentioned existing in prior technology problem, the purpose of this invention is to provide the report method between the reciprocity Resource and Admission Control Sub-system entity in a kind of network, thereby can improve the agreement of reciprocity RACS inter-entity, for the agreement of reciprocity RACS inter-entity provides a kind of mechanism that reports.
The objective of the invention is to be achieved through the following technical solutions:
Report method in a kind of network between the reciprocity Resource and Admission Control Sub-system RACS entity, described reciprocity RACS entity comprises reciprocity entity of carrying control function BCFE, described method specifically comprises step:
Certain BCFE sends the reporting message that carries effective information in A, the network to another BCFE;
B, described another BCFE handle accordingly according to the information that described certain BCFE that receives reports.
2, the report method between the reciprocity Resource and Admission Control Sub-system entity in the network according to claim 1 is characterized in that, the agreement between the described reciprocity BCFE comprises that resource connects initialization RCIP agreement.
Described method also comprises:
Described another BCFE replys response message to described certain BCFE, and described reporting message and described response message carry out asynchronous transmission.
Described steps A specifically comprises:
Certain BCFE sends to another BCFE and carries the reporting message of error message in the network.
Described error message comprises:
Label switched path LSP is unavailable or downstream BCFE is unavailable.
Described step B specifically comprises:
After described another BCFE receives the reporting message that carries error message, discharge or do not discharge relevant calling as required.
As seen from the above technical solution provided by the invention, the agreement that the present invention is perfect between the peer-entities BCFE of RACS, for connection status between the BCFE or error event etc. provide a kind of approach that effectively reports, proposed a kind of reciprocity RACS inter-entity agreement report mechanism.

Embodiment
Main purpose of the present invention is in order to improve the agreement between reciprocity RACS (the resource access control subsystem) entity, proposed between a kind of reciprocity RACS entity agreement report mechanism.
Describe the present invention in detail below in conjunction with accompanying drawing, the concrete handling process of the method for the invention comprises the steps: as shown in Figure 2
Step 21: a BCFE is to another BCFE reporting message.
Reciprocity RACS entity of the present invention mainly refers to BCFE, agreement between the BCFE comprises the agreement of RCIP (Resource Connection Initial Protocol) or type etc., in these agreements, need to define the message passing mechanism between some BCFE, such as, reporting between the BCFE (NOTIFY) mechanism.
So, after a BCFE obtains certain effective information, can send reporting message to another BCFE as required and report this message.
Described reporting message is different from response message, because the concrete state of the message that it is received before not needing to be concerned about, and response message is general relevant with request message.
This reporting message is asynchronous transmission.
Step 22: another BCFE handles accordingly according to the message of receiving.
A described BCFE usually carries certain effective information in the reporting message that another BCFE sends, receive that the BCFE of this reporting message usually needs to handle accordingly according to this effective information.
The BCFE that receives this reporting message can return or not return response message as required.
Such as, reporting message usually carries and the relevant information of various error situations (error conditions).Unavailable etc. as LSP (label switched path) or downstream BCFE.In this case, receive that the BCFE that reports can adopt following dual mode to handle:
1, discharges relevant calling.
2, do not discharge relevant calling.At this moment, the service quality of these callings may be influenced.
In sum, the present invention provides a kind of mechanism that reports for the agreement between the BCFE, and this reports mechanism to be used for the various information that report between BCFE and BCFE.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
