Embodiment
In order to make those skilled in the art person understand the present invention program better, below in conjunction with drawings and embodiments, the embodiment of the present invention is described in further detail.
Before introducing technical solution of the present invention, first application scenarios of the present invention is explained.
For user by user terminal access video website, in this process, the AF server of video website can as third-party application entity, request sets up session with the strategy in carrier network and charging rule functions unit PCRF (the net internal object entity namely in the present invention), realize accurate billing, now, AF understands first and the edge device (anchor entity namely in the present invention of carrier network, anchor entity directly can be exposed to third party, as a kind of example, anchor entity can be presented as protocol converter PC) set up HTTP connection; And then set up Diameter session by PC and PCRF, finally realize the session between third party and user terminal.
In actual application, the situation of multiple AF by the same PCRF of same PC addressing may be there is, as shown in Figure 2, there are 3 AF (to be respectively AF1 simultaneously, AF2, AF3) PCRF is accessed by PC, if PCRF collects the network event needing to report to AF1, but when carrying out event forwarding by PC, PC cannot distinguish that this network event will be transmitted in 3 AF which, that is, the present invention program mainly for be multiple third-party application entity by an anchor entity addressing net internal object entity time, the stream identification problem on same anchor entity caused.
Below in conjunction with accompanying drawing, the present invention program is explained.
See Fig. 3, show the flow chart of the information transferring method embodiment 1 of anchor entity side in the embodiment of the present invention, can comprise:
Step 101, anchor entity receives the first session request that third-party application entity sends, and described first session request comprises the identity information of described third-party application entity and the identity information of net internal object entity.
AF is as session setup side, and first send the first session request to PC, to set up the http session between third-party application entity and anchor entity, the first session request at least comprises following two information:
(1) identity information of third-party application entity
This information spinner will play two aspect effects: one is, in order to make, with it, PC is clearly current sets up whom the third party that HTTP is connected is, so that PC carries out legitimacy authentication to this AF, judge whether this AF has the authority of access carrier network, this embodiment of the present invention is not repeated.Two are, by PC, this information are sent to the PCRF of AF queued session, so that PCRF network event gives the correct time follow-up carrying out, can add in reporting information by this information, as PC carry out flow identify foundation, this be can refer to hereafter introduce.
It should be noted that, the identity information being positioned at the third-party application entity outside operator's mobile communications network can be presented as following at least one item: the IP address (IPv4 address or IPv6 address) of AF, uniform resource position mark URL (Universal Resource Locator), connection identifier between third-party application entity and anchor entity, the embodiment of the present invention can be not specifically limited.Wherein, different according to third-party application entity and the message transfer mechanism adopted between anchor entity, connection identifier can be presented as: if set up the first session by websocket, be then embodied as websocket connection identifier; If set up the first session by HTTP2.0, be then embodied as HTTP connection identifier.
(2) identity information of net internal object entity
If this information spinner in order to make the clear and definite AF of PC current want to set up session to as if who so that PC correctly initiates the second session request to this object, set up Diameter session.
It should be noted that, the identity information of net internal object entity can be presented as: the mark in Diameter territory residing for the Diameter host identification of PCRF and PCRF.In this case, third-party application entity A F carries out net internal object entity PCRF addressing according to the identity information of user terminal UE (User Equipment), determine the mark (Diameter host name and/or the IP address of PCRF can be presented as) of PCRF and the mark in Diameter territory, place, the two identity information as net internal object entity is sent to PC.This is mainly because the corresponding relation between UE identity information and PCRF identity information can carry out pre-configured in advance in third-party application entity A F, so, third-party application entity A F, when knowing UE identity information, by searching configuration relation, can obtain PCRF identity information.
Or, the identity information of net internal object entity also can be presented as: the identity information of user terminal UE, such as, the IP address of UE, IMSI (International Mobile Subscriber Identification, international mobile subscriber identity code), MSISDN (Mobile Station International ISDN number, travelling carriage International ISDN number) etc., the embodiment of the present invention can be not specifically limited this.In this case, the identity information being used for the UE of initial addressing is directly sent to PC as the input information of net internal object entity addressing by third-party application entity A F, net internal object entity PCRF addressing is carried out accordingly by PC, determine the mark of PCRF and the mark in Diameter territory, place thereof, carry out follow-up session establishment process.Corresponding relation between UE identity information and PCRF identity information can carry out pre-configured in advance in anchor entity PC, and so, anchor entity PC, when knowing UE identity information, by searching configuration relation, can obtain PCRF identity information.Consider that third-party application entity A F is the equipment outside carrier network, if net external equipment has the authority of target entity identity information in Diameter territory in addressing net, the fail safe of obvious net internal object entity is lower, therefore using the input information of UE identity information as the addressing of net internal object entity in the manner, carried out the addressing of net internal object entity by the anchor entity PC being positioned at network, the secure session between third-party application entity and net internal object entity can be improved.
In this step, anchor entity receives the mode of the first session request that third-party application entity sends, and the message transfer mechanism by multiple XMLization realizes, such as, and the technology such as websocket, HTTP2.0.Below in websocket mode, the specific implementation of this step is explained, specifically can flow chart shown in Figure 4.
Step 201, described anchor entity is connected by the socket websocket set up based on webpage that once shakes hands with described third-party application entity;
Step 202, described anchor entity receives the described first session request that described third-party application entity transmits in described websocket connection.
Webscoket is TCP (the Transport Control Protocol of the real time implementation providing a full duplex between anchor entity and third-party application entity, transmission control protocol) connect, each webscoket that this TCP connection creates connects the session corresponded between a third-party application entity and anchor entity, thus effectively overcome in traditional HTTP mechanism, all the time http session is initiated by third-party application entity as HTTP client, and the long poll of HTTP or HTTP stream mechanism only can be adopted to carry out the limitation of the function adaptation of non real-timeization for the reporting events of anchor entity.
When setting up websocket and connecting, third-party application entity sends HTTP GET Upgrade request to anchor entity, and a new websocket connection is set up in request; Accordingly, anchor entity by rear, returns Switching Protocol response message to third-party application entity to third-party application entity authentication, shows that the websocket successfully established therebetween connects.So, in the websocket connection of setting up, just can by the http session message encapsulation between third-party application entity and anchor entity in Onmessage method, and call Send method and to conversate the transmission of message.Such as, http session message between third-party application entity and anchor entity: the procedure message such as the reporting events (Traffic Plane Event Reporting) of AF session establishment, AF session modification, AF session termination, Business Stream plane can be encapsulated in Onmessage method, call Send method be sent to other end entity by the entity of one end.
In addition, it should be noted that, between third-party application entity and anchor entity, terminate communication, after termination http session, third-party application entity can call close method to discharge the resource shared by websocket connection, comprises the TCP resource of transport layer.
Step 102, described anchor entity and described third-party application entity set up the first session, and sending the second session request to described net internal object entity, described second session request comprises the identity information of described anchor entity and the identity information of described third-party application entity.
After anchor entity receives the first session request of third-party application entity transmission, can set up the first session according to the identity information of the third-party application entity comprised in request with corresponding third-party application entity, namely HTTP connects; Meanwhile, anchor entity also can send the second session request, to set up the Diameter session of anchor entity and this net internal object inter-entity according to the identity information of net internal object entity comprised in request to the net internal object entity of correspondence.
It should be noted that, in the second session request, at least should comprise following two information:
(1) identity information of third-party application entity, namely the identity information of the third-party application entity of the first session request is sent in step 101 to anchor entity, so that it is whom that net internal object entity can know request with the third party of its session, and then after getting network event, can notify that anchor entity accurately carries out stream and identifies.
(2) whose request the identity information of anchor entity, clearly know to make net internal object entity and set up the second session with it, specifically can be presented as the mark in Diameter territory residing for the Diameter host identification of anchor entity and anchor entity.
In addition, in the second session request, also can comprise the identity information of net internal object entity further, judge that to make net internal object entity whether current second session request is for oneself, can be not specifically limited this embodiment of the present invention.
Step 103, described anchor entity and described net internal object entity set up the second session, and receive the information that described net internal object entity reports, and described packets of information is containing the identity information of reported event and third-party application entity.
Step 104, described reported event is transmitted to corresponding third-party application entity according to the identity information of the third-party application entity comprised in described information by described anchor entity.
The second session is set up at anchor entity and net internal object entity, namely after Diameter session, if net internal object entity collects the network event needing to report to third-party application entity, then can send reporting information to anchor entity, carry out information forwarding by anchor entity.Particularly, in reporting information except comprising network event that needs report, also should comprise this network event for the identity information of third-party application entity, anchor entity identifies so that can carry out stream according to this identity information, and then the network event comprised in reporting information is accurately transmitted to corresponding third-party application entity, solve stream identification problem.
It should be noted that, as above introduce, anchor entity is after receiving the first session request, following action can be performed: first session of setting up anchor entity and third-party application inter-entity, the second session request is sent to net internal object entity, in addition, anchor entity also can be set up and safeguard a list corresponding with net internal object entity, what add in table is the identity information of all third-party application entities corresponding with this net internal object entity, that is, what add in table is the identity information of all third-party application entities by same anchor entity addressing same net internal object entity.See Fig. 2 examples cited, PC sets up and in the list corresponding with PCRF safeguarded, interpolation be the identity information of AF1, AF2, AF3.That is, the corresponding net internal object entity of a list that anchor entity is safeguarded also is the second session that a corresponding anchor entity and net internal object entity are set up.
Based on the list that anchor entity is safeguarded, the embodiment of the present invention additionally provides the scheme of two kinds of terminations session, explains one by one below.
Scheme one
See Fig. 5, show the flow chart of the information transferring method embodiment 2 of anchor entity side in the embodiment of the present invention, can comprise:
Step 301, anchor entity receives the first session request that third-party application entity sends, and described first session request comprises the identity information of described third-party application entity and the identity information of net internal object entity.
Step 302, described anchor entity and described third-party application entity set up the first session, and sending the second session request to described net internal object entity, described second session request comprises the identity information of described anchor entity and the identity information of described third-party application entity.
Step 301,302 with step 101,102 identical, repeat no more herein.
Step 303, the identity information of described third-party application entity adds in list by described anchor entity, and described list is corresponding with described net internal object entity.
It should be noted that, anchor entity and third-party application entity set up the first session, anchor entity sends to net internal object entity the identity information that the second session request, anchor entity add third-party application entity in list, the execution sequence of three process actions can not affect the technique effect of the embodiment of the present invention, therefore the embodiment of the present invention does not do considered critical to this.
Step 304, described anchor entity and described net internal object entity set up the second session, and receive the information that described net internal object entity reports, and described packets of information is containing the identity information of reported event and third-party application entity.
Step 305, described reported event is transmitted to corresponding third-party application entity according to the identity information of the third-party application entity comprised in described information by described anchor entity.
Step 304,305 with step 103,104 identical, repeat no more herein.
Step 306, described anchor entity receives the session termination request treating that termination third-party application entity sends, and treats the identity information of termination third-party application entity in described session termination request described in comprising.
The situation of termination session is needed if occur in conversation procedure, as: out of touch between user and third party's network, or it is congested that third party's network judges that certain region occurs, the lower user of teste preference is needed to carry out alleviate congestion, namely third-party application entity can send session termination request to anchor entity, in order to terminate the session without the need to maintaining again.
As Fig. 2 examples cited, when AF1 needs the first session between termination and PC, AF1 can as treating that termination third-party application entity sends session termination request to PC.
Step 307, the identity information of third-party application entity of waiting described in whether described anchor entity judges only to preserve in described list to terminate, if so, then perform step 308, described anchor entity empties described list and described second session that terminates; If not, then perform step 309, described anchor entity delete in described list preserve described in wait the identity information of third-party application of terminating.
Anchor entity checks its list safeguarded, and carries out differentiated treatment according to check result after receiving the session termination request sent until termination third-party application entity:
(1) if only add the identity information of the third-party application entity that needs to be terminated in list, then illustrate why anchor entity now keeps the second session with net internal object entity, it is the network event obtained to forward net internal object entity to the third-party application entity of waiting to terminate, if now this unique third-party application entity also will terminate session, so anchor entity is also just without the need to continuing maintenance second session again, therefore anchor entity can directly terminate, the second session of itself and net internal object inter-entity, namely terminates Diameter session; Meanwhile, anchor entity also can empty list, and discharges the resource that list takies, the first session of termination and third-party application inter-entity.
(2) if in list except treating the identity information of termination third-party application entity, also preserve the identity information of other third-party application entity, as the session of AF1 request termination, but also preserve AF2 in the list that anchor entity is safeguarded, the identity information of AF3, now, in order to ensure that anchor entity is after termination with the session of AF1, still can normally to AF2, AF3 transmission network event, anchor entity should continue to keep the second session with net internal object inter-entity, simultaneously, anchor entity also should delete the identity information treating termination third-party application entity preserved in local list, termination and the first session between it, in the examples described above, namely the HTTP terminated between PC and AF1 connects, continue to retain PC and AF2, HTTP between AF3 connects.
(3) if do not find the identity information treating termination third-party application entity in lists, anchor entity can not carry out any process to this session termination request, and certainly, also can send fault alarm, the embodiment of the present invention can be not specifically limited this.
Scheme two
As such scheme one, anchor entity only can safeguard a list, namely anchor entity sets up the session of multiple third-party application entity to same net internal object entity, correspondingly, preserves the identity information of multiple third-party application entities of this net internal object entity session in list.Also can be understood as, the Diameter session of what list was corresponding is anchor entity and this net internal object inter-entity.
In addition, anchor entity sets up the session of multiple third-party application entity to different net internal object entity, corresponding to this, anchor entity will safeguard multiple lists, be the list of each net internal object entity maintaining, often open the identity information that list is respectively used to the multiple third-party application entities preserving corresponding net internal object entity.Also can be understood as, often open list respectively to should the Diameter session of certain net internal object inter-entity in anchor entity and multiple net internal object entity (it should be noted that, under normal circumstances, at synchronization, anchor entity and certain net internal object entity only set up a Diameter session).
Such as, PC1 sets up AF1, session between AF2, AF3 and PCRF1 as the agency of PCRF1, can continue to set up session between AF4, AF5 and PCRF2 as the agency of PCRF2 simultaneously, agency as PCRF3 sets up the session between AF6 and PCRF3, even also can set up the session between more AF and PCRF, only property for referencial use illustrates herein, repeats no more.In this case, anchor entity will create and safeguard at least two lists, often open the corresponding net internal object entity of list, as above-mentioned example, PC1 will safeguard three lists, Diameter session between a corresponding PC1 and PCRF1 of list, that add in table is AF1, AF2, AF3, the Diameter session between a corresponding PC1 and PCRF2 of list, and that add in table is AF4, AF5, Diameter session between a corresponding PC1 and PCRF3 of list, that add in table is AF6.
Safeguard the scheme of at least two lists based on anchor entity, the embodiment of the present invention additionally provides the information transferring method embodiment 3 of anchor entity side, see Fig. 6, can comprise:
Step 401, anchor entity receives the first session request that third-party application entity sends, and described first session request comprises the identity information of described third-party application entity and the identity information of net internal object entity.
Step 402, described anchor entity and described third-party application entity set up the first session, and sending the second session request to described net internal object entity, described second session request comprises the identity information of described anchor entity and the identity information of described third-party application entity.
Step 401,402 with step 101,102 identical, repeat no more herein.
Step 403, described anchor entity searches pending list corresponding to the identity information of described net internal object entity from least two lists safeguarded, and is added in described pending list by the identity information of described third-party application entity.
It should be noted that, anchor entity and third-party application entity set up the first session, anchor entity sends to net internal object entity the identity information that the second session request, anchor entity add third-party application entity in pending list, the execution sequence of three process actions can not affect the technique effect of the embodiment of the present invention, therefore the embodiment of the present invention does not do considered critical to this.
Step 404, described anchor entity and described net internal object entity set up the second session, and receive the information that described net internal object entity reports, and described packets of information is containing the identity information of reported event and third-party application entity.
Step 405, described reported event is transmitted to corresponding third-party application entity according to the identity information of the third-party application entity comprised in described information by described anchor entity.
Step 404,405 with step 103,104 identical, repeat no more herein.
Step 406, described anchor entity receives the session termination request treating that termination third-party application entity sends, and treats the identity information of termination third-party application entity and the described identity information treating the net internal object entity that termination third-party application entity is corresponding in described session termination request described in comprising.
Step 407, described anchor entity search from least two lists safeguarded described in wait to terminate the list corresponding to identity information of net internal object entity corresponding to third-party application entity.
Step 408, to wait described in whether described anchor entity judges only to preserve in the list found to terminate the identity information of third-party application entity, if, then perform step 409, the list found described in described anchor entity empties, and the second session between the termination net internal object entity corresponding with described third-party application entity of waiting to terminate; If not, then perform step 410, described anchor entity delete in described list preserve described in wait the identity information of third-party application of terminating.
Step 408 ~ 410 are identical with step 307 ~ 309, repeat no more herein.
In addition, it should be noted that, anchor entity is safeguarded to the scheme of at least two lists, treat also only to comprise the identity information treating termination third-party application entity in the session termination request that termination third-party application entity sends, corresponding to this, anchor entity often can open list according to treating that the identity information of termination third-party application entity is searched one by one, and conversate termination.Certainly, first find according to the identity information of net internal object entity the list added and treat termination third-party application entity identities information above in scheme two, from list, delete identity information again to conversate termination, also can improve the efficiency of embodiment of the present invention session termination.
Corresponding with the information transfer process of the anchor entity side introduced above, the embodiment of the present invention additionally provides the information transfer process of third-party application entity side, the flow chart of the information transferring method of third-party application entity side that specifically can be shown in Figure 7, can comprise:
Step 501, third-party application entity sends the first session request to anchor entity, and described first session request comprises the identity information of described third-party application entity and the identity information of net internal object entity; The identity information of described third-party application entity is used for being forwarded to described net internal object entity when described anchor entity sends the second session request to described net internal object entity;
Step 502, described third-party application entity receives the response that described anchor entity returns, and sets up the first session with described anchor entity;
Step 503, after described anchor entity and described net internal object entity set up the second session, described third-party application entity receives the reported event that described anchor entity forwards according to the identity information of described third-party application entity, and the identity information of described third-party application entity and described reported event are sent to described anchor entity by described net internal object entity.
The present embodiment mainly from third-party application entity side, to the explanation explanation that information transfer process of the present invention carries out.Similarly, the present embodiment also needs to set up following two sessions:
1. the first session
First session to be initiated to anchor entity by third-party application entity and is set up, detailed process can see above introduce, repeat no more herein.It should be stressed, the identity information of the third-party application entity in the first session request, except when anchor entity and third-party application entity set up the first session, (mainly carrying out legitimacy authentication to third-party application entity) uses, also for this information being added in the second session request, net internal object entity is sent to by anchor entity, like this, when net internal object entity collects reported event, just this information can be sent to anchor entity together with reported event, identify so that anchor entity carries out stream on this basis, correct is forwarded to third-party application entity by reported event.
Particularly, the process that third-party application entity sends the first session request to anchor entity can be presented as: described third-party application entity is connected by the socket websocket set up based on webpage that once shakes hands with described anchor entity; Described third-party application entity transmits described first session request to described anchor entity on described websocket connects.
