Description
Technical field
The present invention relates to mobile communication technology field, particularly a kind of Origin-State-Id AVP sending method based on Diameter and device.
Background technology
RADIUS(Remote Authentication Dial In User Service, remote customer dialing authentication system) agreement is current most widely used a kind of AAA(Authentication AuthorizationAccounting, Certificate Authority is kept accounts) agreement, and Diameter(diameter) agreement is the upgraded version of radius protocol, by IETF(Internet Engineering Task Force, Internet Engineering Task group) AAA working group as follow-on aaa protocol standard.
In Diameter, use Origin-State-Id(source-state-mark) AVP(Attribute-Value-Pair, attribute-content-to group) carry out indication equipment state, also referred to as status information of equipment.This AVP carries in every bar interaction message, is convenient to the equipment state that recipient understands transmit leg.
If the value of the Origin-State-Id AVP that recipient judges in the Origin-State-Id AVP received changes, can think that the equipment state of the transmit leg that former Origin-State-Id AVP is corresponding is lost, need to remove the local resource about the transmit leg of former Origin-State-Id AVP.After recipient receives Origin-State-Id AVP, need, by host name, the domain name of the local transmit leg preserved of character string traversal, to find the state before the equipment of this transmit leg.Such processing mode, has increased the weight of the processing load of recipient, greatly slow down the processing speed of recipient.
LTE(Long Term Evolution, Long Term Evolution) the SAE(System ArchitectureEvolution of network, System Architecture Evolution) network topology structure of framework is illustrated in fig. 1 shown below, Gx interface is positioned at PGW(and PDN GW, Public Data Network Gateway, 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.Policing rule is configured to PCC rule and is handed down to PGW by PCRF, and PGW is tied to these rules in corresponding carrying, is issued to service surface, is undertaken performing these rules, thus reach the object of policy control by service surface.
Information interactive process between PGW and 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 feeds back CCA-I message and receives CCA(Credit Control Answer to PGW, PGW, Credit Control Answer) after-I confirms to set up session, the success of session establishment between the two.
Upgrade conversation procedure and comprise two kinds of situations.Wherein a kind of situation as shown in Figure 3A, initiated to upgrade conversation procedure by PGW.PGW sends CCR-U message to PCRF, asks more new session, and PCRF feeds back CCA-U message to PGW, confirms to set up to upgrade conversation procedure.
And another kind of situation, as shown in Figure 3 B, initiated to upgrade conversation procedure by PCRF, PCRF by the request of more new session by RAR(Re Auth Request, again authentication request) message sends to PGW, PGW will confirm to set up the RAA(Re Auth Answer of more new session, authentication response again) message feedback is to PCRF.
Delete conversation procedure as shown in Figure 4, the CCR-T message that session is deleted in request is sent to PCRF by PGW, and PCRF feeds back CCA-T message to PGW after deleting session.
Information interactive process between above-mentioned PGW and PCRF is mainly by two pairs of message, and CCR/CCA message and RAR/RAA message realize.Origin-State-Id AVP is all carried in CCR/CCA message and RAR/RAA message.
In the prior art, transmitting terminal needs the Origin-State-Id AVP carrying this equipment in every bar Gx interface message.Receiving terminal needs the local Origin-State-Id AVP searched in device storage information by character string in local record after receiving message, whether the value of the Origin-State-Id AVP relatively received 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, by Gx interface, carry out interacting message based on Diameter.Diameter defines Origin-State-Id AVP, and whether this AVP equipment occurred was restarted for being detected same entity device.When PGW network element (or PCRF network element) receives multiple Origin-State-Id AVP of same sender transmission, the Origin-State-Id AVP be currently received if compare is larger than the value of the last Origin-State-IdAVP received, can think that this equipment state is lost, and on the basis of the upper Origin-State-Id AVP once received, carry out all sessions stop.When PGW network element or PCRF network element detect this situation, need the resource removing the local all sessions carried out on the upper Origin-State-Id AVP basis once received.
Origin-Host (source-main frame) and Origin-Realm (source-domain name) AVP is used to come the source of identification message in Diameter.Origin-Host adopts character string type, in order to show the source node producing 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 sent each time, Origin-Host and Origin-Realm that Origin-Host and Origin-Realm in the Origin-State-Id AVP received is corresponding with the opposite equip. list of local maintenance compares by receiving terminal, from the opposite equip. list of local maintenance, find out the Origin-State-Id value corresponding with this transmitting terminal of having preserved, compare with the Origin-State-Id value be currently received, judge whether this equipment state loses.
This method of carrying Origin-State-Id AVP in each message sent by Gx interface, although can after opposite equip. loss of state, remove the resource of all sessions that the local Origin-State-IdAVP received based on the last time carries out, but owing to carrying Origin-State-Id AVP in each message sent by Gx interface, and receiving terminal often receives the message of once carrying Origin-State-Id AVP, Origin-Host and Origin-Realm in Origin-Host and Origin-Realm in the opposite equip. list of local maintenance and the message that is currently received just is needed to compare, judge whether this equipment state loses.This method repeating character string comparison consumes system resource greatly, and adds the time of processing messages.

Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in detail.
The embodiment of the present invention can be, but not limited to send Origin-State-Id AVP state by following manner to equipment and carries out record.In the embodiment of the present invention, define 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) all represent that the status information of equipment of this locality is not sent to the situation of receiving terminal by transmitting terminal; And Sended_Proc(had sent, and receive response message) then represent that the status information of equipment of this locality has been sent to the situation of receiving terminal by transmitting terminal.
Local record to should the Origin-State-Id AVP of receiving terminal to send state be Send_Null or Sending_Proc time, send local Origin-State-Id AVP to receiving terminal.
Before carrying out information interaction at every turn, transmitting terminal local record to should the Origin-State-Id AVP of receiving terminal to send state be Sended_Proc time, do not send local Origin-State-Id AVP to receiving terminal.
Consult shown in Fig. 5, in the embodiment of the present invention, after transmitting terminal establishes a communications link based on Diameter and receiving terminal, the detailed process carrying out information interaction with receiving terminal is as follows:
Step 501: before each transmission message, transmitting terminal judges whether the Origin-State-Id AVP of this locality to be sent to receiving terminal, if so, carry out step 502, otherwise, carry out step 503.
In the embodiment of the present invention, transmitting terminal according to local record to should receiving terminal Origin-State-IdAVP send condition adjudgement whether the Origin-State-Id AVP of this locality is sent to receiving terminal, as previously mentioned, Send_Null(did not send) and Sending_Proc( send, also do not receive response message) all represent that the status information of equipment of this locality is not sent to the situation of receiving terminal by transmitting terminal; And Sended_Proc(had sent, and receive response message) then represent that the status information of equipment of this locality has been sent to the situation of receiving terminal by transmitting terminal.
Step 502: transmitting terminal no longer sends local Origin-State-Id AVP to this receiving terminal.
In the embodiment of the present invention, the concrete executive mode of step 502 can be divided into following three kinds (being only citing to be not limited thereto):
1) transmitting terminal is determined to send local status information of equipment to receiving terminal before this sends, and when receiving the status information of equipment of this receiving terminal of receiving terminal feedback first, judge the Origin-State-Id AVP of this locality to be sent to receiving terminal, and no longer send local Origin-State-Id AVP to this receiving terminal.
Such as, 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 by this locality to should receiving terminal record Origin-State-Id AVP send state be set to Sending_Proc.Before this sends, transmitting terminal receive this receiving terminal feedback carry the response message of Origin-State-Id AVP of this receiving terminal after, when being defined as the Origin-State-Id AVP receiving this receiving terminal first, record receives the Origin-State-Id AVP of this receiving terminal that receiving terminal sends first, by this locality to the Origin-State-Id AVP of receiving terminal record should sending state and 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 received feedback is identical with the status information of equipment of this receiving terminal of local record, judge the Origin-State-Id AVP of this locality to be sent to receiving terminal, and no longer send local Origin-State-Id AVP to this receiving terminal.
Such as, if carried out information interaction with this receiving terminal before transmitting terminal, the new Origin-State-Id AVP that this receiving terminal sends is received in information interactive process, and the Origin-State-Id value of this new Origin-State-Id AVP is identical with the Origin-State-Id value in the Origin-State-Id AVP of this receiving terminal of local record, then by this locality to the Origin-State-Id AVP of receiving terminal record should sending state and 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 present invention, the concrete executive mode of step 503 can be divided into following three kinds (being only citing to be not limited thereto):
1) when transmitting terminal is determined not send local Origin-State-Id AVP to receiving terminal before this sends, then the Origin-State-Id AVP of this locality is sent to receiving terminal, and by this locality to should receiving terminal record Origin-State-Id AVP send state be set to Sending_Proc.
Such as, when transmitting terminal judges that the Origin-State-Id AVP of local corresponding receiving terminal record sends state as Send_Null, determine 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-IdAVP of this locality is sent to this receiving terminal again, and by this locality to should receiving terminal record Origin-State-Id AVP send state be set to Sending_Proc.
3) transmitting terminal determines that the Origin-State-Id value in the up-to-date Origin-State-Id AVP receiving this receiving terminal that receiving terminal sends is different from the Origin-State-Id value in the Origin-State-Id AVP of this receiving terminal of local record, then judge the Origin-State-Id AVP of this locality not to be sent to receiving terminal, record the up-to-date Origin-State-Id value receiving this receiving terminal that receiving terminal sends, and send local Origin-State-Id AVP to this receiving terminal.
Such as, transmitting terminal is determined to send local Origin-State-IdAVP to receiving terminal before this sends, and the Origin-State-Id value in the Origin-State-Id AVP of this receiving terminal that the up-to-date receiving terminal that receives sends than local to should Origin-State-Id value in the Origin-State-Id AVP of receiving terminal record greatly, then record the up-to-date Origin-State-Id AVP receiving this receiving terminal that receiving terminal sends, the Origin-State-Id AVP of this locality is sent to this receiving terminal, and by this locality to should receiving terminal record Origin-State-Id AVP send state be set to Sending_Proc.Under this kind of situation is usually found in the sight that in transmitting terminal and receiving terminal reciprocal process, receiving terminal is restarted for some reason; now; receiving terminal can by the Origin-State-Id value+1 in Origin-State-Id AVP after restarting, and what thus just there will be transmitting terminal and receiving terminal records inconsistent situation.
With a kind of concrete application scenarios, further description is made to above-described embodiment below.
In practical application, transmitting terminal can be PGW, and receiving terminal can be PCRF, or transmitting terminal is PCRF, and receiving terminal is PGW.And the information interaction between PGW and PCRF can by the Gx Interface realization for charging control and policy control.Be described respectively for both of these case below.
Such as, the Origin-State-Id AVP of this locality, before this sends CCR-I message to PCRF, is not sent to PCRF if judge by PGW, then need to carry local Origin-State-Id AVP in the message sent at this; Origin-State-Id AVP was sent to this PCRF if judge, and received the response message of this PCRF feedback, and the status information of equipment of this PCRF does not have modified, then do not need to carry local Origin-State-Id AVP in the message sent at this.
On the other hand, the Origin-State-Id AVP of this locality, before this sends CCA message to PGW, is not sent to PGW if judge by PCRF, then need to carry local Origin-State-Id AVP in the message sent at this; Origin-State-Id AVP was sent to this PGW if judge, and received the response message of this PGW feedback, and the status information of equipment of this PGW does not have modified, then do not need to carry local Origin-State-Id AVP in the message sent at this.
Corresponding with above-described embodiment, receiving terminal receive transmitting terminal send carry the message of Origin-State-Id AVP of this transmitting terminal after, need the Origin-State-Id AVP in processing messages, 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, all represent that the status information of equipment of this locality is not sent to the situation of this transmitting terminal by receiving terminal, need again to send local Origin-State-Id AVP to this transmitting terminal; And Sended_Proc represents that the status information of equipment of this locality has been sent to the situation of transmitting terminal by receiving terminal, before carrying out information interaction at every turn, if receiving terminal local record to should the Origin-State-IdAVP of transmitting terminal to send state be Sended_Proc, no longer send local Origin-State-Id AVP to transmitting terminal.
In the embodiment of the present invention, receiving terminal, after receiving transmitting terminal and sending the Origin-State-IdAVP of this transmitting terminal, carries out the detailed process of information interaction as shown in Figure 7 with transmitting terminal, comprising:
