Specific embodiment
In order to which those skilled in the art is made to more fully understand the present invention program, below in conjunction with the accompanying drawings with embodiment to this
Inventive embodiments are described in further detail.
Before technical solution of the present invention is introduced, first the application scenarios of the present invention are explained.
By taking user is by user terminal access video website as an example, AF servers of video website can conduct during this
Third-party application entity, request and the Policy and Charging Rules Function PCRF (nets i.e. in the present invention in carrier network
Interior target entity) session is established, accurate billing is realized, at this point, AF can be first with the edge device of carrier network (i.e. in the present invention
Anchor entity, anchor entity can be directly exposed to third party, and as a kind of example, anchor entity can be presented as protocol converter
PC HTTP connections) are established；Then Diameter sessions are established by PC and PCRF again, it is final to realize between third party and user terminal
Session.
In actual application, it is possible that multiple AF address the situation of same PCRF by same PC, such as
Shown in Fig. 2, while there are 3 AF (being respectively AF1, AF2, AF3) to access PCRF by PC, if PCRF collects needs on AF1
The network event of report, but when carrying out event forwarding by PC, the network event cannot be distinguished in PC will be transmitted to for which in 3 AF
It is a, that is to say, that the present invention program is primarily directed to multiple third-party application entities and addresses one by an anchor entity
In net during target entity, the identification problem of the stream on same anchor entity of initiation.
The present invention program is explained below in conjunction with the accompanying drawings.
Referring to Fig. 3, the flow chart of the information transferring method embodiment 1 of anchor entity side in the embodiment of the present invention is shown,
It may include：
Step 101, anchor entity receives the first session request that third-party application entity is sent, first session request
The identity information of target entity in identity information and net comprising the third-party application entity.
AF first sends the first session request, to establish third-party application entity and anchor point reality as session setup side to PC
Http session between body, the first session request include at least following two information：
(1) identity information of third-party application entity
This information mainly plays two aspects：When in order to make that PC clearly currently establishes that HTTP is connected with it the 3rd
Whom side is, so that PC carries out legitimacy authentication to the AF, judges whether the AF has the permission of access carrier network, to this
Inventive embodiments are without repeating.Second is that this information is sent to the PCRF of AF queued sessions by PC to, so that PCRF is follow-up
Give the correct time on network event, this information can be added to and reported in information, the foundation of stream identification is carried out as PC, to this
It can refer to and hereafter introduce.
It should be noted that the identity information of the third-party application entity outside operator's mobile communications network can embody
To be at least one of following：The IP address (IPv4 addresses or IPv6 addresses) of AF, uniform resource position mark URL (Universal
Resource Locator), the connection identifier between third-party application entity and anchor entity, the embodiment of the present invention, which can not be done, to be had
Body limits.Wherein, according to the difference of the message transfer mechanism used between third-party application entity and anchor entity, connection identifier
It can be presented as：If establishing the first session by websocket, websocket connection identifier is embodied as；If pass through
HTTP2.0 establishes the first session, then is embodied as HTTP connection identifier.
(2) in net target entity identity information
This information is primarily to it is whom that the clear and definite AF of PC is made, which currently to want to set up the object of session, so that PC is correctly to this
Object initiates the second session request, establishes Diameter sessions.
It should be noted that the identity information of target entity can be presented as in net：The Diameter host identifications of PCRF with
And the mark in Diameter domains residing for PCRF.In this case, third-party application entity A F is according to user terminal UE (User
Equipment identity information) carries out netting interior target entity PCRF addressing, and determining the mark of PCRF (can be presented as PCRF's
Diameter host name and/or IP address) and place Diameter domains mark, will be both as the body of target entity in net
Part information is sent to PC.This correspondence being primarily due between UE identity informations and PCRF identity informations can be in advance the 3rd
It is pre-configured in square application entity AF, in this way, third-party application entity A F is in the case where knowing UE identity informations, by looking into
Look for configuration relation, you can obtain PCRF identity informations.
Alternatively, the identity information of target entity can be also presented as in net：The identity information of user terminal UE, for example, UE
(International Mobile Subscriber Identification, international mobile user identity are known by IP address, IMSI
Other code), MSISDN (Mobile Station International ISDN number, mobile station International ISDN number) etc., this
Inventive embodiments can be not specifically limited this.In this case, third-party application entity A F will directly be used to initially address
UE identity information as net in target entity addressing input information be sent to PC, carried out netting interior target entity accordingly by PC
PCRF is addressed, and is determined the mark of PCRF and its mark in place Diameter domains, is carried out subsequent session establishment process.UE identity
Correspondence between information and PCRF identity informations can be pre-configured in anchor entity PC in advance, in this way, anchor entity
PC is in the case where knowing UE identity informations, by searching for configuration relation, you can obtains PCRF identity informations.In view of third party
Application entity AF is the equipment outside carrier network, if net external equipment is with target entity identity in Diameter domains in addressing net
The permission of information, it is clear that the security of target entity is relatively low in net, therefore in this mode using UE identity informations as target in net
The input information of entity addressing, by the anchor entity PC being located in network net the addressing of interior target entity, can improve the
Secure session in tripartite's application entity and net between target entity.
In this step, anchor entity receives the mode for the first session request that third-party application entity is sent, can be by more
The message transfer mechanism of kind XMLization is realized, for example, the technologies such as websocket, HTTP2.0.It is in a manner of websocket below
Example, is explained the specific implementation of this step, for details, reference can be made to flow chart shown in Fig. 4.
Step 201, the anchor entity establishes web-based set with the third-party application entity by once shaking hands
Connect word websocket connections；
Step 202, the anchor entity receives what the third-party application entity transmitted in the websocket connections
First session request.
Webscoket provides the TCP of the real time implementation of a full duplex between anchor entity and third-party application entity
(Transport Control Protocol, transmission control protocol) connects, and what is created in this TCP connection is each
Webscoket connections correspond to the session between a third-party application entity and anchor entity, so as to effectively overcome tradition
HTTP mechanism in, http session is initiated as HTTP clients by third-party application entity always, and for anchor entity
Event reports the limitation for the function adaptation for being only capable of carrying out non real-timeization using HTTP long polls or HTTP stream mechanisms.
When establishing websocket connections, third-party application entity sends HTTP GET Upgrade to anchor entity please
It asks, a new websocket connection is established in request；Accordingly, anchor entity to third-party application entity authentication by it is rear then
Switching Protocol response messages are returned to third-party application entity, show to be successfully established therebetween
Websocket connections.In this way, in the websocket connections of foundation, so that it may will be between third-party application entity and anchor entity
Http session message be encapsulated in Onmessage methods, and Send methods is called to conversate the transmission of message.For example, the
Http session message between tripartite's application entity and anchor entity：AF session establishments, AF session modifications, AF session terminations, industry
The event of business plane of flow reports procedure messages such as (Traffic Plane Event Reporting) that can be encapsulated in
In Onmessage methods, by the entity of one end Send methods is called to be sent to other end entity.
In addition, it is necessary to explanation, when terminating communication between third-party application entity and anchor entity, terminate http session
Afterwards, third-party application entity can call close methods to discharge the occupied resource of websocket connections, including transport layer
TCP resources.
Step 102, the anchor entity establishes the first session, and the target into the net with the third-party application entity
Entity sends the second session request, and second session request includes the identity information of the anchor entity and the third party should
With the identity information of entity.
Anchor entity is received after the first session request of third-party application entity transmission, you can is included according in request
The identity information of third-party application entity establish the first session, i.e. HTTP connections with corresponding third-party application entity；Meanwhile
Anchor entity can also into corresponding net, target entity sends the according to the identity information of target entity in the net included in request
Two session requests, to establish the Diameter sessions in anchor entity and the net between target entity.
It should be noted that following two information should be at least included in the second session request：
(1) in the identity information of third-party application entity, i.e. step 101 the of the first session request is sent to anchor entity
The identity information of tripartite's application entity, whom the third party that request and its session are understand that net interior target entity is, and then
After network event is got, anchor entity can be notified accurately to carry out stream identification.
(2) identity information of anchor entity, so that target entity clearly knows that whose request establishes the second meeting with it in net
Words can specifically be presented as the mark in Diameter domains residing for the Diameter host identifications and anchor entity of anchor entity.
In addition, it can also further comprise the identity information for netting interior target entity in the second session request, so that target in net
Entity judges that current second session request whether for oneself, can be not specifically limited this embodiment of the present invention.
Step 103, the anchor entity establishes the second session with target entity in the net, and receives target in the net
The information that entity reports, described information include the identity information of reported event and third-party application entity.
Step 104, the anchor entity according to the identity information of the third-party application entity included in described information by institute
It states reported event and is transmitted to corresponding third-party application entity.
Target entity establishes the second session in anchor entity and net, i.e., after Diameter sessions, if target entity in net
The network event for needing to report to third-party application entity is collected, then can be sent to anchor entity and report information, it is real by anchor point
Body is forwarded into row information.Specifically, report in information in addition to comprising the network event that reports is needed, should also contain the network
The identity information for the third-party application entity that event is directed to, so that anchor entity can carry out stream identification according to the identity information,
And then the network event included in information will be reported to be accurately forwarded to corresponding third-party application entity, solve the problems, such as stream identification.
It should be noted that such as introduction made above, anchor entity can perform following after the first session request is received
Action：The first session between anchor entity and third-party application entity, the second session request of target entity transmission into net are established,
In addition, anchor entity can also be established and safeguard one and the corresponding list of target entity in net, add in table be with
The identity information of the corresponding all third-party application entities of target entity in the net, that is to say, that is added in table is all logical
Cross the identity information that same anchor entity addresses the third-party application entity of target entity in same net.Referring to Fig. 2 examples cited,
In the list corresponding with PCRF that PC is established and safeguarded, addition be AF1, AF2, AF3 identity information.That is, anchor point
One list of entity maintaining corresponds to target entity namely a corresponding anchor entity in a net and is established with target entity in net
The second session.
Based on anchor entity safeguard list, the embodiment of the present invention additionally provide two kinds termination session scheme, below one
One is explained.
Scheme one
Referring to Fig. 5, the flow chart of the information transferring method embodiment 2 of anchor entity side in the embodiment of the present invention is shown,
It may include：
Step 301, anchor entity receives the first session request that third-party application entity is sent, first session request
The identity information of target entity in identity information and net comprising the third-party application entity.
Step 302, the anchor entity establishes the first session, and the target into the net with the third-party application entity
Entity sends the second session request, and second session request includes the identity information of the anchor entity and the third party should
With the identity information of entity.
Step 301,302 with step 101,102 identical, details are not described herein again.
Step 303, the identity information of the third-party application entity is added in list by the anchor entity, the row
Table is corresponding with target entity in the net.
It should be noted that anchor entity establishes the first session, the anchor entity target into net with third-party application entity
The second session request of entity transmission, anchor entity add the identity information of third-party application entity into list, and three processing are dynamic
The execution sequence of work does not interfere with the technique effect of the embodiment of the present invention, therefore the embodiment of the present invention does considered critical not to this.
Step 304, the anchor entity establishes the second session with target entity in the net, and receives target in the net
The information that entity reports, described information include the identity information of reported event and third-party application entity.
Step 305, the anchor entity according to the identity information of the third-party application entity included in described information by institute
It states reported event and is transmitted to corresponding third-party application entity.
Step 304,305 with step 103,104 identical, details are not described herein again.
Step 306, the anchor entity receives the session termination request that third-party application entity to be terminated is sent, the meeting
The identity information of the third-party application entity to be terminated is included in words termination request.
If occurs the situation for needing termination session in conversation procedure, such as：It is out of touch between user and third party's network,
Or third party's network judges that congestion occurs for some region, it is necessary to teste preference relatively low user alleviates congestion, the
Tripartite's application entity can send session termination request to anchor entity, to terminate the session without maintaining again.
Such as Fig. 2 examples cited, when AF1 needs to terminate the first session between PC, AF1 can be used as third party to be terminated
Application entity sends session termination request to PC.
Step 307, the anchor entity judges the third-party application reality to be terminated whether is only preserved in the list
The identity information of body, if it is, performing step 308, the anchor entity empties the list and second session that terminates；
If it is not, then performing step 309, the anchor entity deletes the body of the third-party application to be terminated preserved in the list
Part information.
Anchor entity is received after the session termination request that termination third-party application entity is sent, and checks its row safeguarded
Table, and be handled differently according to inspection result：
(1) if only addition needs to be terminated the identity information of third-party application entity in list, illustrate anchor entity this
When why in net target entity keep the second session, be in order to third-party application entity terminate forwarding net in target reality
The network event that body obtains, if this only one third-party application entity will also terminate session at this time, then anchor entity is also
Need not be further continued for keep the second session, its second session between target entity in net therefore anchor entity can directly terminate, i.e.,
Terminate Diameter sessions；Meanwhile anchor entity can also empty list, and the resource of list occupancy is discharged, termination and third party
The first session between application entity.
(2) if in list in addition to the identity information of third-party application entity to be terminated, other third parties are also preserved
The identity information of application entity, as AF1 ask termination session, but anchor entity safeguard list in also preserve AF2, AF3
Identity information at this point, in order to ensure anchor entity after the session with AF1 that terminates, remains to normally forward network to AF2, AF3
Event, anchor entity should continue to keep and net in the second session between target entity, meanwhile, anchor entity should also delete local row
The identity information of the third-party application entity to be terminated preserved in table, termination and the first session between it, in the examples described above,
That is the HTTP connections between termination PC and AF1, continue to retain the HTTP connections between PC and AF2, AF3.
(3) if not finding the identity information of third-party application entity to be terminated in lists, anchor entity can not be right
Session termination request carries out any processing, certainly, can also send fault alarm, the embodiment of the present invention can not do this specific limit
It is fixed.
Scheme two
Such as said program one, anchor entity can only safeguard a list, i.e. anchor entity establishes multiple third-party applications
Entity correspondingly, in list preserves multiple third parties of target entity session in the net to the session of target entity in same net
The identity information of application entity.It is also understood that it is in anchor entity and the net between target entity that list is corresponding
Diameter sessions.
In addition, anchor entity establishes session of multiple third-party application entities to target entity in different nets, corresponding
In this, anchor entity will safeguard multiple lists, and target entity safeguards a list in as each net, and every list is used respectively
In the identity information for preserving multiple third-party application entities of target entity in corresponding net.It is also understood that every list
Corresponding to the Diameter sessions in some net in the anchor entity and multiple nets in target entity between target entity respectively (needs
What is illustrated is, it is generally the case that in synchronization, anchor entity only establishes a Diameter meeting with target entity in some net
Words).
For example, PC1 establishes the session between AF1, AF2, AF3 and PCRF1 as the agency of PCRF1, while can continue to make
Session between AF4, AF5 and PCRF2 is established for the agency of PCRF2, the agency as PCRF3 is established between AF6 and PCRF3
Session or even session between more AF and PCRF can be also established, only make referential herein for example, repeating no more.At this
In the case of kind, anchor entity will create and safeguard at least two lists, and every list corresponds to target entity in a net, as above
Example is stated, PC1 will safeguard three lists, and a list corresponds to the Diameter sessions between PC1 and PCRF1, added in table
It is AF1, AF2, AF3, a list corresponds to the Diameter sessions between PC1 and PCRF2, and that added in table is AF4, AF5, and one
Zhang Liebiao corresponds to the Diameter sessions between PC1 and PCRF3, and that added in table is AF6.
The scheme of at least two lists is safeguarded based on anchor entity, the embodiment of the present invention additionally provides the letter of anchor entity side
Transfer approach embodiment 3 is ceased, referring to Fig. 6, it may include：
Step 401, anchor entity receives the first session request that third-party application entity is sent, first session request
The identity information of target entity in identity information and net comprising the third-party application entity.
Step 402, the anchor entity establishes the first session, and the target into the net with the third-party application entity
Entity sends the second session request, and second session request includes the identity information of the anchor entity and the third party should
With the identity information of entity.
Step 401,402 with step 101,102 identical, details are not described herein again.
Step 403, the anchor entity searches the identity of target entity in the net from least two lists of maintenance
The corresponding pending list of information, and the identity information of the third-party application entity is added in the pending list.
It should be noted that anchor entity establishes the first session, the anchor entity target into net with third-party application entity
Entity sends the identity information that the second session request, anchor entity add third-party application entity into pending list, three
The execution sequence of processing action does not interfere with the technique effect of the embodiment of the present invention, therefore the embodiment of the present invention is done strictly not to this
It limits.
Step 404, the anchor entity establishes the second session with target entity in the net, and receives target in the net
The information that entity reports, described information include the identity information of reported event and third-party application entity.
Step 405, the anchor entity according to the identity information of the third-party application entity included in described information by institute
It states reported event and is transmitted to corresponding third-party application entity.
Step 404,405 with step 103,104 identical, details are not described herein again.
Step 406, the anchor entity receives the session termination request that third-party application entity to be terminated is sent, the meeting
Identity information comprising the third-party application entity to be terminated and the third-party application entity to be terminated in words termination request
The identity information of target entity in corresponding net.
Step 407, the anchor entity searched from least two lists of maintenance described in third-party application to be terminated it is real
List in the corresponding net of body corresponding to the identity information of target entity.
Step 408, whether only preserving the third party to be terminated in the list that the anchor entity judgement is found should
With the identity information of entity, if it is, performing step 409, the anchor entity empties the list found, and terminates
The second session in net corresponding with the third-party application entity to be terminated between target entity；If it is not, then perform step
410, the anchor entity deletes the identity information of the third-party application to be terminated preserved in the list.
Step 408~410 are identical with step 307~309, and details are not described herein again.
In addition, it is necessary to explanation, for the scheme that anchor entity safeguards at least two lists, third party to be terminated
The identity information of third-party application entity to be terminated can also be only included in the session termination request that application entity is sent, is corresponded to
This, anchor entity can search every list one by one according to the identity information of third-party application entity to be terminated, and conversate end
Knot.Certainly, first found in scheme two above according to the identity information of target entity in net and add third-party application reality to be terminated
The list of body identity information, then be removed from the list identity information and conversate termination, it can also improve session of the embodiment of the present invention
The efficiency of termination.
Corresponding with the information transfer process of anchor entity side described above, the embodiment of the present invention additionally provides third party
The information transfer process of application entity side for details, reference can be made to the information transferring method of third-party application entity side shown in Fig. 7
Flow chart, it may include：
Step 501, third-party application entity sends the first session request to anchor entity, and first session request includes
The identity information of target entity in the identity information and net of the third-party application entity；The identity of the third-party application entity
Information is used to be forwarded to target in the net when target entity sends the second session request into the net in the anchor entity
Entity；
Step 502, the third-party application entity receives the response that the anchor entity returns, and is built with the anchor entity
Vertical first session；
Step 503, after target entity establishes the second session in the anchor entity and the net, the third-party application
Entity receives the reported event that the anchor entity is forwarded according to the identity information of the third-party application entity, the third party
