Description
Technical field
The present invention relates to the communications field, specifically, relate to distributed processing system(DPS) and method that MGC (Media Gateway Controller) and MGW (media gateway) in NGN in the communications field (next generation network is as the WCDMA/CDMA2000/TD-SCDMA/SOFTSWITCH) system go up jumbo H.248 agreement.
Background technology
H.248 agreement is adopted by tissues such as 3GPP/3GPP2, and as the NGN network carrying and the consensus standard that control separates, control is set up in the gateway control and the carrying that are mainly used between MGC and the MGW.
By H.248 communicating by letter, message can select text mode or binary mode to encode between MGC and the MGW.H.248 message-length is usually between 100 to 300 bytes.Through the coding message format as shown in Figure 1, message H.248 is nested from outside to inside to be affairs (Transaction)/action (Action)/order (Command) successively:
Affairs: affairs are made up of some actions, and affairs have integrality, and action in the same affairs and order request order are carried out.
Action: action is formed by some command in combination, and action generally has concrete implication, and in particular cases, an action is made up of an order.Action is actually the sign of Management Information Base.
Order: order is the base unit that MGC and MGW realize interactive information, comprises the various command parameter in the order.The operand of order is context (Context), and context is distinguished with Context identifier (Context ID).Context is corresponding with calling, safeguards destination node (Termination) state that participates in calling.
A complete calling procedure, will be between MGC and MGW mutual 20～60 H.248 orders, finishing same contextual calling control operation, each command interaction is encapsulated into and forms in the affairs H.248 that message sends to the other side.
H.248 protocol processes scheme commonly used at present is as Fig. 2: MGC or MGW externally have one to a plurality of interface boards, are responsible for receiving outside H.248 message or sending H.248 message; H.248 the message that receives delivered to and decoded on the Protocol Processing Board, and finish transaction, context maintenance H.248 and the coding that externally sends message on this plate.This scheme whole system has only a plate to carry out protocol processes, and it is very big to be subject to processing the device capabilities limits, also is difficult to handle jumbo H.248 agreement even processor is very capable.With PENTIUM III700MHZ CPU is example, and H.248 disposal ability is usually less than 100 calling/seconds.
In the NGN system, the MGC disposal ability has above demand (such as the MSC-SERVER of 3GPP) 1000 calling/seconds, and the mode that H.248 simple veneer is handled can not satisfy system requirements.Top simple process mode can not be used the mode expanding system disposal ability that increases processor, because message is not H.248 known the processor of message correspondence before not having decoding, if the random H.248 message that will receive of interface board is issued each disposable plates decoding, must cause a large amount of decoded message not belong to this plate and handle.(n＞1) the individual processor of supposing that n is arranged, the message of (1-1/n) * 100% needs to transmit from probability, and the number of times of forwarding is between 1 to n-1.Processor is many more, and the probability of forwarding is big more, and the number of times that is forwarded to final context disposable plates is many more.Model with 1000 calling/seconds of 10 processor processing calculates, there is 90% message to transmit, frequent a large amount of processors of forwards consumption and intercommunication bandwidth, in addition, because message-length H.248 is unfixing, decoded message-length is uncertain, for the allocation manager in communication data district is brought difficulty.At present, still there is not satisfactory ground solution of the above problems to propose.
Summary of the invention

Embodiment
Fig. 1, Fig. 2 are described in background technology, do not repeat them here.
Fig. 3 is a structure chart of the present invention, comprises 3 links: externally message transmissions/reception message pre decoding is distributed link, H.248 centralized maintenance link, distribution process link H.248.These three link combinations realize jumbo H.248 protocol processes, and can realize level and smooth capacity extensions.
Message transmission/reception message pre decoding distribution link externally sends H.248 message; Internally receive external message, judge behind the pre decoding that issuing the distribution process processor still issues the centralized maintenance processor, the pre decoding link is discerned each processor that enters the H.248 message of system, is the key link that the present invention realizes the distributed treatment distribution.Centralized maintenance processing links processing messages receives the error message that the pre decoding link can not be discerned, perhaps handle maintain message at whole M GW, the centralized maintenance processing links is safeguarded the proper communication between the MGC/MGW, safeguards the consistency of resource and call state between them.The distributed treatment link is handled the H.248 message that pre decoding link branch sends, and generation is called out relevant H.248 message and sent by message transmission/reception pre decoding link veneer.
Fig. 4 is the interaction diagrams between three main processing links among Fig. 3.Message transmission/reception message pre decoding distribution link is responsible for the external information receiving and transmitting of system, and the pre decoding judgement that receives message.The centralized maintenance processing links receives the H.248 maintain message that message distribution link is sent, or handles the maintenance request that distributed processors is sent, distribution of notifications formula processor or inform H.248 entity of opposite end by the message sending link after disposing.The message that the main processing messages distribution of distributed treatment link link is come produces message according to the call progress situation and sends to H.248 entity of opposite end, and the message between the distributed processors is to comprise the processing request of a plurality of actions in the affairs and handle response message.
Fig. 5 is the handling process of external message transmission/reception message pre decoding distribution link among Fig. 4, and this link can be to be divided into interface board and pre decoding plate, and also can integrate becomes a plate.The Transaction ID (Transaction Identifier) that send this locality is as a kind of resource, for each H.248 distribution processor distribute one section interval, on pre decoding and message point of departure, can find the table of comparisons of affairs ID and processor, this H.248 the transactions requests sent of entity dispose when replying the other side, pre decoding at first finds the alignment processing device according to replying ID.For MGC, continue to be decoded to EVENT REQUEST ID (event number sign), event number identifies as a kind of resource, the allocation table that the resident event number of reserving for each distribution processor of interface board identifies, and the event number message that receives can find the corresponding distributed processor according to this table.For MGW, if the message of receiving is the H.248 entity request of sending of opposite end, pre decoding proceeds to finds out first CONTEXT ID (Context identifier), if this Context identifier is newly-built or empty, specify a distributed processors to handle, the Context identifier of this calling just drops in the Context identifier interval of this processor correspondence, if this Context identifier meets the context interval range of certain distribution processor, message is issued distributed processors and handled.Illegal Transaction Identifier or event number sign or Context identifier message perhaps at the message and the error message of ROOT and "-" sign, are handled by the centralized maintenance processor is unified.
The centralized maintenance processor is safeguarded the H.248 state synchronized between the communication entity, accepts the registration of MGW during as MGC, initiates the registration to MGC during as MGW.This link is also finished error message simultaneously and is handled, and the processing of message such as Resource Availability maintenance is ordered as SERVICE CHANGE H.248.
Fig. 6 is the handling process of distributed treatment link among Fig. 3.There is not attaching relation in the mutual equality of relation between the distributed processors.The message of handling on the distributed processors has two classes, a class be H.248 in the message context return and oneself handle, another kind of is to also have not the context of management to one's name.This processor will be handled the context of oneself, judges then whether this message is that other distribution processors are transmitted, if, then reply result to this forwarding processor, message sends if not then being encoded into H.248.If find to also have the context of other processor processing behind the intact own context of this processor processing,, be encoded into H.248 message transmission together after waiting other processor processing to finish context then earlier to relevant distribution processor distribution.The distributed processors secondary distribution is the situation that occurs a plurality of actions in the affairs in order to handle, if the processor of these context correspondences is different, receive that at first the distributed processors of this message need be born distribution, the wait acknowledge task of Unified coding then.
In the model of system and method for the present invention, the load of pre decoding message distribution and centralized maintenance management processor seldom, distribution processor increase H.248 disposal ability as required can superpose.The pre decoding operand is very little, and NGN full call is about 20 to 60 message H.248, the centralized maintenance processor is at most only handled one of them message (can only handle registration message as required), therefore the disposal ability of this model can reach more than 20 times of simple process mode in theory, can satisfy all high-capacity H .248 processing demands among the NGN.
