The method comprises the following step that: a sending end communicates with a receiving end according to the Diameter protocol, namely before a message is sent each time, the sending end judges whether local equipment state information is sent to the receiving end, if the local equipment state information is sent to the receiving end, the sending end does not send the local equipment state information any more, otherwise, the sending end sends the local equipment state information to the receiving end, so that the problems of consumption of system resources and prolonging of message processing time which are caused by a reason that the receiving end is required to judge whether an equipment state of the sending end is lost according to a received Origin-State-Id value during information interaction each time in the prior art are solved.
Description
Technical field
The present invention relates to the mobile communication technology field, particularly a kind of Origin-State-Id AVP sending method and device based on Diameter.
Background technology
RADIUS(Remote Authentication Dial In User Service, the remote customer dialing authentication system) agreement is present most widely used a kind of AAA(Authentication Authorization Accounting, the Certificate Authority book keeping operation) agreement, and Diameter(diameter) agreement is the upgraded version of radius protocol, by IETF(Internet Engineering Task Force, Internet Engineering task groups) AAA working group as follow-on aaa protocol standard.
In Diameter, use Origin-State-Id(source-state-sign) AVP(Attribute-Value-Pair, attribute-content-to group) and come the indication equipment state, be also referred to as status information of equipment.This AVP carries in every interaction message, is convenient to the equipment state that the recipient understands transmit leg.
If the recipient judges the value of the Origin-State-Id AVP among the Origin-State-Id AVP that receives and changes, can think that the equipment state of the transmit leg that former Origin-State-Id AVP is corresponding loses, need to remove the resource of local transmit leg about former Origin-State-Id AVP.After the recipient receives Origin-State-Id AVP, need to by host name, the domain name of the local transmit leg of preserving of character string traversal, find the equipment state before of this transmit leg.Such processing mode has increased the weight of recipient's processing load, has greatly slowed down recipient's processing speed.
LTE(Long Term Evolution, Long Term Evolution) the SAE(System Architecture Evolution of network, System Architecture Evolution) network topology structure of framework is illustrated in fig. 1 shown below, it is PDN GW that the Gx interface is positioned at PGW(, Public Data Network Gateway, the public data network gateway) and PCRF(Policy and Charging Rules Function, strategy and charging rule functions) between, be mainly used in charging control and policy control.PCRF is configured to the PCC rule downloading to PGW with policing rule, and PGW is tied to these rules in the corresponding carrying, is issued to service surface, carries out these rules by service surface, thereby reaches the purpose of policy control.
Information interactive process between PGW and the PCRF comprises: create conversation procedure, upgrade conversation procedure, delete conversation procedure etc.
Wherein, create conversation procedure as shown in Figure 2, PGW sends CCR(Credit Control Request, credit control request)-I message is to PCRF, session is set up in request, and PCRF feedback CCA-I message is to PGW, and PGW receives CCA(Credit Control Answer, Credit Control Answer)-and after I confirms to set up session, session establishment success between the two.
Upgrade conversation procedure and comprise two kinds of situations.Wherein a kind of situation initiates to upgrade conversation procedure by PGW as shown in Figure 3A.PGW sends CCR-U message to PCRF, asks more new session, and PCRF feedback CCA-U message is to PGW, and affirmation is set up and upgraded conversation procedure.
And another kind of situation, shown in Fig. 3 B, initiate to upgrade conversation procedure by PCRF, the PCRF more request of new session passes through RAR(Re Auth Request, again authentication request) message sends to PGW, PGW will confirm to set up more the RAA(Re Auth Answer of new session, again authentication response) message feedback is to PCRF.
Delete conversation procedure as shown in Figure 4, PGW will ask the CCR-T message of deletion session to send to PCRF, and feedback CCA-T message is to PGW after the PCRF deletion session.
Information interactive process between above-mentioned PGW and the PCRF mainly is by two pairs of message, and CCR/CCA message and RAR/RAA message realize.All carried Origin-State-Id AVP in CCR/CCA message and the RAR/RAA message.
In the prior art, transmitting terminal need to carry the Origin-State-Id AVP of this equipment in every Gx interface message.Receiving terminal is received to be needed after the message to search local Origin-State-Id AVP in the local record by character string in device storage information, whether the value of the Origin-State-Id AVP that relatively receives is identical with the value of local Origin-State-Id AVP, and carries out subsequent treatment according to comparative result.
At EPS(Evolved Packet Systerm, evolved packet system) in, PGW network element and PCRF network element carry out interacting message by the Gx interface based on Diameter.Diameter has defined Origin-State-Id AVP, and whether this AVP for detection of same entity device equipment occured restarts.When PGW network element (or PCRF network element) is received a plurality of Origin-State-Id AVP of same sender's transmission, if it is larger than the value of the last Origin-State-Id AVP that receives to compare the current Origin-State-Id AVP that receives, can think that this equipment state loses, and carry out all sessions on the basis of the upper Origin-State-Id AVP that once receives and stop.When PGW network element or PCRF network element detect this situation, need to remove the resource of local all sessions of carrying out on the upper Origin-State-Id AVP basis that once receives.
Use Origin-Host (source-main frame) and Origin-Realm (source-domain name) AVP to come the source of identification message in the Diameter.Origin-Host adopts character string type, in order to show the source node that produces Diameter message; Origin-Realm adopts character string type, in order to represent territory, Diameter message producer place.Transmitting terminal carries Origin-State-Id AVP in the message that sends each time, corresponding Origin-Host and Origin-Realm comparison in the opposite equip. tabulation of receiving terminal with the Origin-Host among the Origin-State-Id AVP that receives and Origin-Realm and local maintenance, from the opposite equip. tabulation of local maintenance, find out the Origin-State-Id value corresponding with this transmitting terminal of having preserved, compare with the current Origin-State-Id value that receives, judge whether this equipment state loses.
This method of in each message that sends by the Gx interface, carrying Origin-State-Id AVP, although can be after the opposite equip. loss of state, the resource of all sessions that the local Origin-State-Id AVP that receives based on the last time of removing carries out, but owing in each message that sends by the Gx interface, carried Origin-State-Id AVP, and receiving terminal is whenever received the message of once carrying Origin-State-Id AVP, just the Origin-Host in the opposite equip. tabulation of local maintenance and Origin-Host and the Origin-Realm in Origin-Realm and the current message that receives need to be compared, judge whether this equipment state loses.This method that repeats character string comparison has consumed system resource greatly, and has increased the time of processing messages.

Embodiment
In the embodiment of the invention, designed a kind of based on the Diameter(diameter) the Origin-State-Id AVP sending method of agreement, transmitting terminal is only when judging that not status information of equipment with this locality is sent to receiving terminal, just in sending to the message of receiving terminal, carry the Origin-State-Id value, like this, can save the Message Processing time of communicating pair.
Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
The embodiment of the invention can but be not limited to by following manner equipment to be sent Origin-State-Id AVP state and carry out record.In the embodiment of the invention, defined the structure of an enumeration type, as follows:
Typedef?enum{
Send_Null; Do not send
Sending_Proc; Send, also do not receive response message
Sended_Proc; Sent, and received response message
}OriginStateSendStatus
Wherein, Send_Null(did not send) and Sending_Proc( send, also do not receive response message) represent that all transmitting terminal is not sent to the status information of equipment of this locality the situation of receiving terminal; And Sended_Proc(had sent, and received response message) represent that then transmitting terminal has been sent to the status information of equipment of this locality the situation of receiving terminal.
When the Origin-State-Id AVP transmission state to should receiving terminal of local record is Send_Null or Sending_Proc, send local Origin-State-Id AVP to receiving terminal.
Before carrying out information interaction, when transmitting terminal is Sended_Proc at the Origin-State-Id AVP transmission state to should receiving terminal of local record, do not send local Origin-State-Id AVP to receiving terminal at every turn.
Consult shown in Figure 5ly, in the embodiment of the invention, after transmitting terminal established a communications link based on Diameter and receiving terminal, the detailed process that carries out information interaction with receiving terminal was as follows:
Step 501: each send message before, transmitting terminal judges whether the Origin-State-Id AVP of this locality is sent to receiving terminal, if, carry out step 502, otherwise, carry out step 503.
In the embodiment of the invention, transmitting terminal judges whether the Origin-State-Id AVP of this locality is sent to receiving terminal according to the Origin-State-Id AVP transmission state to should receiving terminal of local record, as previously mentioned, Send_Null(did not send) and Sending_Proc( send, also do not receive response message) represent that all transmitting terminal is not sent to the status information of equipment of this locality the situation of receiving terminal; And Sended_Proc(had sent, and received response message) represent that then transmitting terminal has been sent to the status information of equipment of this locality the situation of receiving terminal.
Step 502: transmitting terminal no longer sends local Origin-State-Id AVP to this receiving terminal.
In the embodiment of the invention, the concrete executive mode of step 502 can be divided into following three kinds (only for being not limited to for example this):
1) transmitting terminal is determined to send local status information of equipment to receiving terminal before this sends, and when receiving first the status information of equipment of this receiving terminal of receiving terminal feedback, judgement is sent to receiving terminal with the Origin-State-Id AVP of this locality, and no longer sends local Origin-State-Id AVP to this receiving terminal.
For example, transmitting terminal is when carrying out information interaction with receiving terminal first, record host name and the domain name of this receiving terminal, the Origin-State-Id AVP of this locality is sent to receiving terminal, and this locality to should receiving terminal the Origin-State-Id AVP transmission state of record be set to Sending_Proc.Before this sends, transmitting terminal is behind the response message of the Origin-State-Id AVP that has carried this receiving terminal that receives this receiving terminal feedback, when being defined as receiving first the Origin-State-Id AVP of this receiving terminal, record receives the Origin-State-Id AVP of this receiving terminal of receiving terminal transmission first, this locality to should receiving terminal the Origin-State-Id AVP transmission state of record be set to Sended_Proc, and no longer send local Origin-State-Id AVP to this receiving terminal.
2) transmitting terminal is determined to send local status information of equipment to receiving terminal before this sends, and when the facility information state of this receiving terminal of the receiving terminal that receives feedback is identical with the status information of equipment of this receiving terminal of local record, judgement is sent to receiving terminal with the Origin-State-Id AVP of this locality, and no longer sends local Origin-State-Id AVP to this receiving terminal.
For example, if carried out information interaction with this receiving terminal before the transmitting terminal, in information interactive process, receive the new Origin-State-Id AVP that this receiving terminal sends, and the Origin-State-Id value among the Origin-State-Id AVP of the Origin-State-Id value of the Origin-State-Id AVP that this is new and this receiving terminal of local record is identical, then this locality to should receiving terminal the Origin-State-Id AVP transmission state of record be set to Sended_Proc, and no longer send local Origin-State-Id AVP to this receiving terminal.
Step 503: transmitting terminal sends local Origin-State-Id AVP to this receiving terminal.
In the embodiment of the invention, the concrete executive mode of step 503 can be divided into following three kinds (only for being not limited to for example this):
When 1) transmitting terminal is determined not send local Origin-State-Id AVP to receiving terminal before this sends, then the Origin-State-Id AVP with this locality sends to receiving terminal, and this locality to should receiving terminal the Origin-State-Id AVP transmission state of record be set to Sending_Proc.
For example, transmitting terminal is judged when the Origin-State-Id AVP of local corresponding receiving terminal record sends state as Send_Null, determines not send local Origin-State-Id AVP to receiving terminal before this sends.
2) transmitting terminal is determined to send local Origin-State-Id AVP to receiving terminal before this sends, and when not receiving the Origin-State-Id AVP of this receiving terminal of feedback, the Origin-State-Id AVP of this locality is sent to this receiving terminal again, and this locality to should receiving terminal the Origin-State-Id AVP transmission state of record be set to Sending_Proc.
3) transmitting terminal determines that the Origin-State-Id value among the Origin-State-Id AVP of Origin-State-Id value and this receiving terminal of local record among the up-to-date Origin-State-Id AVP that receives this receiving terminal that receiving terminal sends is different, then judgement is not sent to receiving terminal with the Origin-State-Id AVP of this locality, record the up-to-date Origin-State-Id value that receives this receiving terminal of receiving terminal transmission, and send local Origin-State-Id AVP to this receiving terminal.
For example, transmitting terminal is determined to send local Origin-State-Id AVP to receiving terminal before this sends, and the Origin-State-Id value among the Origin-State-Id AVP of this receiving terminal that the up-to-date receiving terminal that receives sends than local to the Origin-State-Id value in should the Origin-State-Id AVP of receiving terminal record greatly, then record the up-to-date Origin-State-Id AVP that receives this receiving terminal of receiving terminal transmission, the Origin-State-Id AVP of this locality is sent to this receiving terminal, and this locality to should receiving terminal the Origin-State-Id AVP transmission state of record be set to Sending_Proc.This kind situation can appear under the sight that receiving terminal is restarted for some reason in transmitting terminal and the receiving terminal reciprocal process usually; at this moment; receiving terminal is understood the Origin-State-Id value among the Origin-State-Id AVP+1 after restarting, thereby the inconsistent situation of record of transmitting terminal and receiving terminal just can occur.
The below makes further description with a kind of concrete application scenarios to above-described embodiment.
In the practical application, transmitting terminal can be PGW, and receiving terminal can be PCRF, and perhaps, transmitting terminal is PCRF, and receiving terminal is PGW.And the information interaction between PGW and the PCRF can be by being used for the Gx Interface realization of charging control and policy control.The below describes respectively as an example of both of these case example.
For example, PGW if judgement is not sent to PCRF with the Origin-State-Id AVP of this locality, then need to carry local Origin-State-Id AVP in the message of this transmission before this sends CCR-I message to PCRF; If judge and sent Origin-State-Id AVP to this PCRF, and received the response message of this PCRF feedback, and the status information of equipment of this PCRF do not change, and then need to not carry local Origin-State-Id AVP in the message of this transmission.
On the other hand, PCRF if judgement is not sent to PGW with the Origin-State-Id AVP of this locality, then need to carry local Origin-State-Id AVP in the message of this transmission before this sends CCA message to PGW; If judge and sent Origin-State-Id AVP to this PGW, and received the response message of this PGW feedback, and the status information of equipment of this PGW do not change, and then need to not carry local Origin-State-Id AVP in the message of this transmission.
Corresponding with above-described embodiment, receiving terminal needs the Origin-State-Id AVP in the processing messages after receiving the message of the Origin-State-Id AVP that carries this transmitting terminal that transmitting terminal sends, and treatment principle is as follows:
When the Origin-State-Id AVP transmission state of the corresponding transmitting terminal of receiving terminal local record is Send_Null or Sending_Proc, represent that all receiving terminal is not sent to the status information of equipment of this locality the situation of this transmitting terminal, need again to send local Origin-State-Id AVP to this transmitting terminal; And Sended_Proc represents that receiving terminal has been sent to the status information of equipment of this locality the situation of transmitting terminal, before carrying out information interaction at every turn, if the Origin-State-Id AVP transmission state to should transmitting terminal at the receiving terminal local record is Sended_Proc, no longer send local Origin-State-Id AVP to transmitting terminal.
In the embodiment of the invention, receiving terminal is after receiving transmitting terminal and sending the Origin-State-Id AVP of this transmitting terminal, and the detailed process that carries out information interaction with transmitting terminal comprises as shown in Figure 7:
Step 701: the status information of equipment that the receiving terminal receiving end/sending end adopts the method for embodiment of the invention design to send;
Step 702: receiving terminal judges that this receives before status information of equipment that this transmitting terminal sends, and whether the status information of equipment of this locality is sent to transmitting terminal, if then carry out step 703, otherwise carry out step 704.
Step 703: receiving terminal no longer sends local status information of equipment.
The embodiment of step 703 can be divided into following two kinds in the embodiment of the invention:
1) this receives before the status information of equipment of this transmitting terminal, and receiving terminal sent local status information of equipment to transmitting terminal, and does not receive the status information of equipment of this transmitting terminal, then no longer sends local status information of equipment.
For example, if this Origin-State-Id AVP that receives transmitting terminal of receiving terminal is what receive first, and this moment is local to be Send_Null to Origin-State-Id AVP transmission state that should the transmitting terminal record, then record host name and the domain name of this transmitting terminal, and the Origin-State-Id AVP of this transmitting terminal that receives, feed back the Origin-State-Id AVP of this receiving terminal to transmitting terminal, and this locality is set to Sending_Proc to Origin-State-Id AVP transmission state that should the transmitting terminal record.
2) this receives before the status information of equipment of this transmitting terminal, sent local status information of equipment to this transmitting terminal, and the status information of equipment of this transmitting terminal that this receives then no longer sends local status information of equipment with identical with the status information of equipment of this receiving terminal of local record.
For example, if this receives before the Origin-State-Id AVP of transmitting terminal at receiving terminal, received the Origin-State-Id AVP of this transmitting terminal, and, this moment receiving terminal to should transmitting terminal the Origin-State-Id AVP transmission state of record be Sended_Proc, and in the identical situation of the Origin-State-Id value in should the Origin-State-Id AVP of transmitting terminal of the Origin-State-Id value of receiving terminal in judging this Origin-State-Id AVP that receives and local record, no longer send Origin-State-Id AVP to transmitting terminal.
Step 704: receiving terminal sends local status information of equipment to transmitting terminal.
In the embodiment of the invention step 704 specifically can be divided into following two kinds of situations:
1) before this receives the status information of equipment of this transmitting terminal, when receiving terminal did not send local status information of equipment to this transmitting terminal, receiving terminal sent local status information of equipment to transmitting terminal.
For example, if receiving terminal did not carry out information interaction (receiving terminal after restarting is judged the equipment that all transmitting terminals are does not have mutual mistake) with this transmitting terminal before judging, then after this receives the Origin-State-Id AVP of this transmitting terminal, record host name and the domain name of this transmitting terminal, simultaneously will this locality to should transmitting terminal the Origin-State-Id AVP transmission state of record be set to Send_Null, and feed back the Origin-State-Id AVP of this receiving terminal to transmitting terminal.
2) before this receives the status information of equipment of this transmitting terminal, receiving terminal sent local status information of equipment to transmitting terminal, and the status information of equipment of this transmitting terminal that this receives with the status information of equipment of this receiving terminal of local record not simultaneously, receiving terminal sends local status information of equipment to transmitting terminal.
For example, if this receives before the Origin-State-Id AVP of transmitting terminal at receiving terminal, received the Origin-State-Id AVP of this transmitting terminal, and, this moment receiving terminal to should transmitting terminal the Origin-State-Id AVP transmission state of record be Sended_Proc, and that receiving terminal is judged the Origin-State-Id value in should the Origin-State-Id AVP of transmitting terminal of Origin-State-Id value and local record among this Origin-State-Id AVP that receives is not identical, then discharge this transmitting terminal based on the resource of former Origin-State-Id AVP, to recording new Origin-State-Id AVP by transmitting terminal, and feed back the Origin-State-Id AVP of this receiving terminal to this transmitting terminal, will be Sending_Proc to Origin-State-Id AVP transmission state that should the transmitting terminal record.This kind situation can appear under the sight that transmitting terminal is restarted for some reason in transmitting terminal and the receiving terminal reciprocal process usually; at this moment; transmitting terminal is understood behind the Origin-State-Id value among the Origin-State-Id AVP+1 after restarting, and new Origin-State-Id AVP is sent to the receiving terminal that need to carry out information interaction.
