Description
Technical field
The present invention relates to mobile communication technology field, particularly a kind of method and system that transmits marginal interface identification services access.
Background technology
At moving communicating field, transmission technology (Transmission technology) refers to utilize the transmittability of different channels to form a complete transmission system, makes information be able to the technology of transmitting.Current most widely used transmission technology has: microwave, PDH (Pseudo-synchronous Digital Hierarchy) (PDH, Plesiochronous Digital Hierarchy), SDH (Synchronous Digital Hierarchy) (SDH, Synchronous Digital Hierarchy), wavelength division multiplexing (WDM, Wavelength Division Multiplexing), EPON (PON, Passive Optical Network), optical transport network (OTN, Optical Transport Network) etc.
From the service signal of the service network equipment such as local switch, change into STM-1(155M by transmission network equipment), STM-4(622M), STM-16(2500M) etc. signal frame structure, or to be directly ethernet format change into send to after STM-N signal by transmission network equipment on transmission network, is sent to opposite end, be translated into again the service signal of former form by the transmission network equipment of opposite end, introduce switch or service access net.For the service network equipment such as switch, transmission has just completed the function that simple signal transmits.What transmission network equipment was realized is signal from low speed (service network) to (transmission network) at a high speed (signal merges---multiplexing), the conversion of (signal separation---demultiplexing) again from high speed to low speed.
What transmit that marginal interface refers to is exactly switch or other service network equipment signal out, is linked into first port on the transmission network equipment in transmission network.
There are following 2 class defects in the transmission limit interface of prior art:
1, the transmission technology such as SDH, PDH system, although there is abundant overhead byte, is not described for service attribute, type specially, and ethernet frame is like this too.
Take SDH as example, the function of SDH expense has been the monitoring management function that SDH signal is provided to refinement layer by layer, the classification of monitoring can the section of being divided into layer monitoring, channel layer monitoring.SDH section overhead, path overhead as shown in Figure 1, comprise RSOH (RSOH), MSOH (MSOH) and administrative unit (AU) pointer.Symbol Δ is the attribute byte relevant with transmission medium.
SDH Higher Order Path Overhead comprises following indication field (VC-3 or VC-4 version):
J1: higher order path trace byte;
B3: higher order path error code monitors BIP-8 byte;
C2: higher order path signal label byte;
G1: channel status byte;
F2: higher order path user passage byte;
H4: position indicating device;
F3: higher order path user passage byte;
K3: APS (APS) path spare bytes;
N1: network operator byte.
SDH lower order path overhead as shown in Figure 2, comprises V5, J2, N2 and K4.
The expense of SDH, by the refinement layer by layer of regenerator section, multiplex section, higher order path, low order channel, monitors for the frame alignment in transmitting procedure, Error detection, clock synchronous, ECC communication, public affair, channel status etc., more lays particular emphasis on concern transmission quality.But obviously lack the description byte for type of service, business source etc.
2, cannot real time correlation between existing resource management system and transmission network management, network element, business:
Existing field of mobile communication, is actually the management that relates to full-service.And the management of full-service only can realize crossing of business in transmission network, only on transmission network, could likely realize the integrated management of full-service.
But, because transmission network is only positioned transparent transmission at present, and do not go initiatively to understand the situation of service network, the whole network of at all not knowing where to begin management.As:
(1), spend a large amount of manpower and materials to build the resource management platform outside communication network.In real work, have two cover systems, actual management and executive arm also must set up respectively.The resources such as human and material resources are wasted greatly.
(2), synchronously difficulty of two cover systems.Resource management system is actually through what be processed to form by hand, must follow strict flow process system.And the transmission network of transmission network management management is only the in real time real current present situation of reaction network.
(3), while encountering problems, still must examine by transmission network.Relate to the factors such as webmaster, Field Force, label, cable.
(4), transmission network self cannot be added up resource service condition.
(5), transmission network is while breaking down, attendant cannot be grasped in real time and be affected service conditions by transmission network management.

Inventor is by the analysis to above-mentioned different business, and business is divided into three large class: E1, SDH(containing POS the most at last), ether (FE, GE).
The embodiment of the present invention one proposes a kind of method of transmitting marginal interface identification services access, comprising:
Between service network and transmission network, unified regulation has free consumption byte or increases discernible overhead byte and indicates as traffic identification;
Service network, before sending signal to transmission network equipment, is filled described traffic identification indication in accordance with regulations.
Transmission network equipment receives after the signal of service network at the marginal interface of transmission, and to traffic identification, indication detects, thereby identifies whether there is business.For example, from transmitting the signal that marginal interface receives, in the expense of extraction, comprise effective traffic identification indication, or the content of the traffic identification extracting indication shows there is business, can be judged as service signal, otherwise be from ring signal.
Fig. 3 shows the traffic identification flow chart of the embodiment of the present invention one, comprises the steps:
Step 301: set up handshake mechanism: service network equipment and transmission network equipment, according to unified standard, in the service signal of both sides' docking, add traffic identification indication and identify.Described service network equipment includes but not limited to switch, router, base station or other equipment.
Step 302: service network equipment adds traffic identification indication: service network equipment, before the service signal sending with Transmission Connection, adds traffic identification indication, so that transmission network equipment Inspection in described service signal.
Step 303: transmission network equipment reads traffic identification indication: the overhead byte of transmission network equipment from service signal extracts traffic identification indication, transmission network equipment is also recorded in the traffic identification indication extracting in the register of master control borad.
Step 304: report transmission network management: when receiving in signal, traffic identification indication is upgraded, and transmission network equipment side master control borad reports current business details to webmaster, and webmaster is record in database, and report query function is provided.And can be automatically associated to concrete business.
Described traffic identification indication is as shown in table 1:
Table 1
The structure of SDH form and the indication of ethernet format traffic identification as shown in Figure 4.Except E1 signal, SDH, containing POS, ethernet signal (GE, FE, 10GE etc.), OTN etc., is all stipulated to indicate as traffic identification using 4 bytes.
The particular content of the traffic identification indication of SDH form and ethernet format is as shown in table 2:
Table 2
E1 signal, uses 1 byte in the 16th time slot to carry out business description, and particular content is as shown in table 3:
Table 3
The embodiment of the present invention two proposes the recognition methods of a kind of transmission network management to related service information, comprising:
When the marginal interface of transmission recognizes after business information, by current detection to business information and the business information that detects of a upper sense cycle compare, if sending, information changes, pass through network element master control borad to more new events of transmission network management reporting service, this business information is simultaneously effective on the corresponding service path of transmission network;
Transmission network management receives after this event, and current business data of description table is upgraded, and retains historical record once in historical business description tables of data simultaneously, and on webmaster, in anomalous event, points out transmission business description information change.Preferably, transmission network management provides provides report query interface to current business data of description table and historical business description tables of data.
Above-mentioned processing mode has following beneficial effect: once there is network failure, if certain important service interruption, can be according to the variation of business description information byte, know that in real time which kind of business is affected, thereby can take effective measures as early as possible recovery business.
What Fig. 5 showed that the embodiment of the present invention two proposes carries out traffic identification realization flow to E1 signal, comprises the steps:
Step 501: the E1(2M that the service network equipment such as switch send to transmission network equipment) signal.
E1 signal there is no the frame structure of SDH, has following 5 types:
(1) non-frame structure E1.What non-frame structure mainly transmitted is data, is characterized in that each frame only has 10 time slot, and all the other 31 time slots do not distinguish.
（2）PCM30。PCM30 maximum can transmit the information of 30 channels, and PCM30 is generally the traffic business for using No. 1 signaling (channel associated signalling).Main feature is the 16th No. 1 signaling of time slot transmission and multi-frame signal and multiframe alarm, and a multi-frame comprises 16 subframes.
（3）PCM31。PCM31 maximum can transmit the information of 31 channels.PCM31 is generally used for signalling system No.7 circuit (being common channel signalling), is characterized in that 31 time slots all can be used for business information.PCM31 does not have multi-frame.The 2M circuit overwhelming majority who uses is at present this type circuit, and in addition, DDN circuit is also the circuit that adopts the type frame structure.
（4）PCM30CRC。This type of frame structure and PCM30 different have been CRC byte many.
（5）PCM31CRC。Equally, compared with PCM31, many CRC bytes.
The E1 signal that switch or router etc. send, the 1st time slot (0 time slot) generally has special purpose (for synchronous etc.), and the embodiment of the present invention two utilizes the 16th time slot to distinguish different business.For this reason, need the equipment such as switch sending before signal, by principle below, in 32 time slots of each frame, all carry out set (signaling circuit and without frame structure E1 except) at the 16th time slot, have 9 kinds of combinations, can represent business and the loopback business (first 4 are fixed as 1111, to distinguish to some extent with signaling circuit) of 8 class different majors, if more than continuous 3 frames, the 16th time slot coincide with combination below, represents the business of respective type.If the 16th time slot is other value, or above the 16th time slot of continuous 3 frames is not identical value, and representative is signaling or without frame circuit.
Table 4 shows the corresponding relation of byte and the type of service of E1 business description:
Table 4
Step 502: transmission network equipment is identified E1 business.
Specifically can there be 2 kinds of modes:
Mode 1: transmission network equipment can be identified the module of 2M payload the 16th time slot content in tributary card increase was carried out, and is reported to host data base before the encapsulation of 2M signal map, so that webmaster extracts business information, was filled up in port description; This mode need be revised transmission network equipment tributary card hardware and software (transmission need increase the software and the hardware chip that extract the 64K time slot content of specifying, and transmission network apparatus suggested is placed on the upper realization of PTN).And modification transmission network management software.Meanwhile, need service network to guarantee according to rule, in corresponding the 16th 64K time slot of E1 signal, write concrete business description information.
Mode 2: add coding schedule ONLINE RECOGNITION by on-the-spot 2M tester; This mode transmission network equipment does not need to make any software and hardware and revises, but business information cannot be directly extracted in transmission network management.Meanwhile, need service network to guarantee according to rule, in corresponding the 16th 64K time slot of E1 signal, write concrete business description information.
Due to traditional MSTP atrophy gradually from now on, PTN becomes main flow gradually, the identification recommendation mode 1 of E1 signal.
For SDH(containing POS) identification of business
In SDH expense, although many reserve bytes can be used for identification services, but current equipment does not all arrange software and hardware for reserve bytes, in order to carry out as far as possible traffic identification in ITU-T standard, simultaneously as far as possible little change equipment software and hardware again, and when meeting raising recognition efficiency, do not affect again existing transmission network equipment room 64K data/voice application, the embodiment of the present invention two is planned in ITU-T advises the SDH frame section overhead byte of concrete regulation not traffic identification indication is set, or traffic identification indication is set in high-order overhead N1 byte.The scheme of the present embodiment is at ITU-T not in the SDH frame section overhead byte of concrete regulation, is chosen at 2 undefined bytes after 2 undefined bytes and the E1 byte after B1 byte, indicates as traffic identification.
Table 5 shows the particular content of POS, Ethernet, the indication of OTN class traffic identification:
Table 5
Traffic identification indication is set and can adopts following any mode:
Mode one: inserted mode frame by frame: 2 undefined bytes after the B1 of every frame byte after 2 undefined bytes and E1 byte are in totally 4 bytes (32), by the pos interface PHY chipset of service network, (service network equipment need carry out hardware and software improvement to support to write reserve bytes to insert related service description, related service is described referring to table 5), transmission network is extracted the correlation reserved byte content of every frame, thus the business of judging (transmission network equipment need carry out software and hardware improvement equally).
Mode two: multi-frame mode: first byte after the B1 byte that is a multi-frame at continuous 4 frames, insert multi-frame start information, as F6H, 28H, F4H, 30H, second undefined byte after B1 byte in multi-frame, (service network equipment need carry out hardware and software improvement to support to write reserve bytes to identify indication by the pos interface PHY chipset Insert service of service network, related service is described referring to table 5), transmission network is extracted the correlation reserved byte content of every group of multi-frame, thus the business of judging (transmission network equipment need carry out software and hardware improvement equally).The advantage of mode two is, the continuous single frames number in multi-frame, can expand as required, to adapt to the needs of following business.
Above two kinds of modes, are all used the not clearly defined byte of ITU-T in section overhead, are conducive to form own standard, and multi-form to be packaged into the business that SDH frame transmits all effective to various.
Be loaded in WDM(OTN by POS mouthpiece) and the business of PTN, all can be with reference to this scheme.Wherein, OTN suggestion is used the reserve bytes (the 13rd, 14 byte) in expense to carry out traffic identification, still advise adopting multi-frame form, it is initial that the 13rd byte of continuous 4 frames is used for describing multi-frame, as F6H, 28H, F4H, 30H, in multi-frame, the 14th byte of continuous 4 frames is used for description business (referring to table 5).Also can expand according to service needed from now on.
For the identification of Ethernet service (FE, GE)
Ethernet frame structure as shown in Figure 7, is respectively application layer, presentation layer, session layer, transport layer, network layer, data link layer and physical layer from top to bottom.Ethernet service, all has means to identify from 1 layer to 7 layers in theory.But the signal of Ethernet encapsulates layer by layer, in order to improve the recognition efficiency of the marginal interface of transmission, do not affect service-aware, need to carry out traffic identification at bottom as far as possible.For this reason, this programme takes the ethernet frame that contains special MAC Address to carry out business description.
Specifically, be exactly Ethernet service net one side apparatus (non-transmission network equipment), do not affecting under the prerequisite of normal discharge, periodically send the frame with special MAC Address, utilize front 4 bytes in the PDU of this frame to describe business.Service network equipment need not be revised hardware, but needs to revise software.
The Ethernet interface plate of transmission network equipment, only need detect this ethernet frame with special MAC Address, extracts bytes of payload content (be business information, only defined temporarily at present front 4 bytes) wherein, reports webmaster.Transmission network equipment need be revised software equally.
The frame structure that Ethernet service is identified the special frames relating to as shown in Figure 6, comprises header, specific purposes address, particular source address, traffic identification indication, payload and check digit successively.Wherein, particular source address and specific purposes address are MAC Address.
Owing to needing service network periodically to send the frame with special MAC Address, and choose in the MAC Address that special MAC Address need to retain from Ethernet protocol.All service signals are in the time of new open electric circuit, and service network side is all strictly carried out set by circuit types code word joint.
The present invention program, by transforming transmitting marginal interface, makes it service condition and the access style of identification services network insertion signal.Service network, sending before the signal such as standard ethernet frame or SDH form, according to the coding rule of agreement, adds part identification byte, or the content of filling in partial frame overhead byte.Transmission network extracts these codings by overhead byte, as the type of differentiated service signal.The specified overhead byte of the application is the idle bytes in ITU-T suggestion, or meets the extra byte of ethernet standard, and it is minimum that the transformation cost of equipment software and hardware reaches.
Compared with prior art, example of the present invention has following technique effect:
1, attendant can grasp transmission network and business interlock situation in real time, can effectively implement network repairing task in the time that fault occurs.
2, can effectively support the whole network resource management, for the network management of full-service provides solid foundation.
3, further expanding the effect of transmission network in communication network, is next step equipment development specific direction.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of protection of the invention.
