In the invention, the soft switch equipment adds the users' number of the calling into the call signaling sent to the media gateway; the media gateway records the corresponding relation between the users' number and the end point of the call; when receiving the tracing instruction, the media gateway finds the corresponding end point from the corresponding relation of users' number, and traces the end point; when outputting the tracing result, according to the end point ID in the tracing result the media gateway find the corresponding users' number and outputs the users' number and the tracing result together.
Description
Technical field
The present invention relates to the communications field, particularly the tracking technique of calling.
Background technology
Traditional being used to transmitted the communication network of voice usually with time division multiplexing (Time DivisionMultiplexing, abbreviation " TDM ") public switched telephone network (Public Switched TelephoneNetwork, be called for short " PSTN ") be the basis, this communication network is based on circuit switching, and the business and the control that relate to voice are all finished by switch.In traditional Circuit Switching Network based on TDM, the structure of switch as shown in Figure 1.Wherein, in calling out control, be extensive use of No.7 signalling system (SignalingSystem 7, are called for short " SS7 ").
Along with data service rapidly increases, traditional network based on circuit switching brings a lot of inconvenience to the data user, for example the communication price height, networking speed is slow, the stand-by period is long, transmission quality is low, increase new business difficulty etc.And along with development of Communication Technique, all business are carried on is jointly progressively becoming possibility on the same data network.Next generation network (Next Generation Network is called for short " NGN ") proposes just in this case, and has obtained development rapidly in recent years.NGN gradually becomes network based on packet switching to traditional PSTN network based on circuit switching, it has carried all business of original PSTN network, simultaneously great amount of data transmission is unloaded (offload) to asynchronous transfer mode (Asynchronous Transfer Mode, be called for short " ATM ")/internetworking agreement (InternetProtocol, be called for short " IP ") in the network to alleviate the heavy burden of PSTN network, according to the new features of ATM/IP technology, increase and strengthened many old and new's business again.In this sense, NGN is based on the PSTN speech network of TDM and the product that merges based on the packet network of ATM/IP, and it makes that integrated services such as voice, video, data become possibility on new generation network.Soft switch (SoftSwitch) technology that NGN adopts professional control and carrying media to be separated, the disposal ability of the network equipment is greatly improved, and it is more professional to handle more traffic and carrying.
(the International Telecommunication UnionTelecommunication Standardization Sector of ITU Telecommunication Standardization Sector, abbreviation " ITU-T ") NGN that provides in February, 2004 is defined as: NGN is a packet network, it provides the multiple business that comprises telecommunication service, can utilize various bandwidth and have service quality (Quality of Service, abbreviation " QoS ") tranmission techniques of ability, the realization business function separates with the bottom tranmission techniques; It allows the user to freely the inserting of different business provider network, and supports universal mobility, realizes consistency and the uniformity of user to the business use.
Wherein, the schematic diagram of the physical model of NGN employing soft switch as shown in Figure 2.Softswitch passes through H.248/ MGCP (Medium Gateway Control Protocol, be called for short " MGCP ") etc. control protocol operation media gateway, SS7 only carries out on Softswitch, also move H.323/ bearer independent call control (Bearer Independent Call Control on the Softswitch, be called for short " BICC ")/conversation initialized protocol (Session Initiation Protocol, be called for short " SIP ") etc. agreement, media gateway (Media Gateway is called for short " MG ") is only carried out resource operation.
In H.248, the media resource operation on the media gateway is that unit carries out with end points (Termination), and endpoint operation is carried out in context (Context) environment basically.
H.248 the message mechanism of agreement as shown in Figure 3.Those of ordinary skill in the art know that H.248 the basic operation unit of protocol message is affairs (Transacion), comprise the operation to some contexts and end points in affairs, and affairs are by transaction identifiers (ID) (32 long words) unique identification.The combination of some affairs in the soft switch, H.248 all of a full call flow process order exactly.About the detail of agreement H.248, can be referring to " Gateway Control Protocol Version 1 " (RFC 3525), Chinese can be translated into " MGCP 1 edition " (Request for Comments standard 3525).
In said process, in case fault such as call setup failure occurs, on media gateway, must calling be followed the tracks of, export H.248 signalling interactive process and internal resource operation, thereby help to carry out location of mistake and deal with problems.Yet because the calling and the resource operation enormous amount of carrying out simultaneously on the media gateway, sequential is staggered, if these information are all exported, can't find out the whole process Signalling exchange and the internal resource operation of each calling.Therefore, must set filtercondition, only H.248 signalling interactive process that the calling that hope is followed the tracks of is relevant and internal resource operation output promptly need to carry out the tracking of indivedual numbers.
In the existing technical scheme,, two kinds of schemes are arranged usually in order in the NGN media gateway, individual user's calling to be followed the tracks of.
Scheme one: at media gateway manual creation tracing task, specify the Subscriber Number that needs tracking, obtain the endpoint id of designated user number correspondence by media gateway.After H.248 media gateway receives message related to calls, resolve endpoint id wherein, judge whether the call flow under this message needs to follow the tracks of, if, then, be used for the inter-process of analyzing medium gateway receiving and the H.248 message of relevant this end points that sends and the operating process output of relevant this end points of medium gateway internal.
Yet owing in the existing protocol, only media resource is operated on the media gateway, Subscriber Number is kept in the storage of subscriber data equipment of soft switch or higher level.In this case, media gateway will obtain corresponding endpoint id according to Subscriber Number, just must inquire about at soft switch (or on storage of subscriber data equipment of higher level), inquires user's endpoint id according to Subscriber Number.Could on media gateway, use endpoint id to carry out the operation such as establishment, deletion of tracing task afterwards.As seen, be unable to do without the participation of soft switch (or storage of subscriber data equipment of higher level) in the whole process, and in the actual networking, the distant situation of the distance of media gateway and soft switch is very general, and the operation of therefore carrying out usertracking on media gateway is difficulty relatively.
Scheme two: the maintenance terminal by webmaster tracking server or soft switch starts a tracking (specifying the Subscriber Number that needs tracking), after following the tracks of startup, by the H.248 signaling of expanding the parameter (as the endpoint id of this Subscriber Number correspondence) of following the tracks of is issued to media gateway by soft switch.When calling that should Subscriber Number was initiated, media gateway was consistent with the end points that soft switch issues according to the end points in the call signaling relatively, judges that then these calling needs are tracked, at once opening entry signaling tracing message.After calling was finished, soft switch reinformed media gateway and stops tracing process.The result who follows the tracks of can be reported to soft switch and webmaster tracking server, also can be kept at media gateway this locality.
This mode needs the participation of Softswitch equally, has following several shortcomings:
1, tracing process must be started by Softswitch or webmaster tracking server, can't follow the tracks of (endpoint id that does not have the Subscriber Number correspondence) according to Subscriber Number voluntarily on the media gateway;
2, do not have the relevant information of Subscriber Number in the record of on media gateway, preserving and exporting, therefore will search tracking results, can only arrive on Softswitch or the webmaster tracking server and carry out according to Subscriber Number;
3,,, influenced by the geographical position so no matter be to need Softswitch or NM server to participate in following the tracks of because the deployment place of webmaster tracking server and soft switch is distant with the distance of media gateway under normal conditions.
Summary of the invention

In the present embodiment, all media gateway under the acquiescence Softswitch are all supported above-mentioned protocol extension.
In step 410, the user makes a call, and Softswitch sends call signaling to media gateway, carries the Subscriber Number of this calling in this call signaling.This Subscriber Number can be rear subscriber number and/or called number.This call signaling can be that end points adds the ADD order.
Then enter step 420, after media gateway is received this call signaling, write down the corresponding relation of the end points of this Subscriber Number and this calling, be kept in the daily record after this Subscriber Number and this Endpoint ID can being associated.
Then enter step 430, media gateway finds corresponding Endpoint ID according to the Subscriber Number in this trace command from daily record when receiving trace command.Because the Subscriber Number that the general always current existence of the Subscriber Number in the trace command is called out, that is to say, when this number makes a call, media gateway has been preserved the relation between its number and the end points, therefore in this step, media gateway can be according to the information of preserving before, find the end points of the Subscriber Number correspondence that needs tracking easily, and need not to inquire about to Softswitch or other higher level equipment, make media gateway to carry out customer call based on Subscriber Number independently and follow the tracks of.
Then enter step 440, media gateway is followed the tracks of this end points, and the record tracking results.
Then enter step 450, if this end of calling, perhaps media gateway is received attendant's END instruction, then enters step 460, stops to follow the tracks of this end points; Otherwise return step 440, continue to follow the tracks of this end points.
Then enter step 470, media gateway is exported the tracking results of this end points.Media gateway finds corresponding Subscriber Number according to the Endpoint ID in this tracking results, this Subscriber Number and this tracking results is associated together outputs to maintenance terminal, shows this Subscriber Number and corresponding tracking results by maintenance terminal.Make the attendant directly on media gateway, to check corresponding tracking results, and need not the participation of Softswitch, implement more independently, be not subjected to the influence in geographical position between media gateway and the Softswitch according to Subscriber Number.
In this flow process, media gateway after stopping to follow the tracks of, the output tracking result; In actual applications, this media gateway can also be in the process of following the tracks of output tracking result synchronously, need equally the back output that is associated of this tracking results and Subscriber Number.
Second embodiment of the invention relates to a kind of call tracking method equally.The present embodiment and first execution mode are roughly the same, and its difference is that in the present embodiment, the attendant disposes trace command in advance on media gateway, comprise the Subscriber Number that one or more needs are followed the tracks of in this trace command.As shown in Figure 5.
In the present embodiment, need carry out suitable expansion to the agreement between existing Softswitch and the media gateway equally, so that carry Subscriber Number in call signaling, concrete extended mode can be identical with first execution mode.And, in the present embodiment, give tacit consent to this Softswitch equally and all support above-mentioned expansion with its following all media gateway.
In step 510, the attendant can dispose trace command by maintenance terminal earlier in advance on this media gateway, comprise the Subscriber Number that at least one need be followed the tracks of in this trace command.
Then enter step 520, when calling out initiation, Softswitch sends call signaling to media gateway, carries the Subscriber Number of this calling in this call signaling.This Subscriber Number can be rear subscriber number and/or called number.This call signaling can be that end points adds the ADD order.
After media gateway is received this call signaling, write down the corresponding relation of the end points of this Subscriber Number and this calling,, then then enter step 530 if this Subscriber Number is included in the Subscriber Number in the trace command, end points to this Subscriber Number correspondence is followed the tracks of, and the record tracking results.Because media gateway can directly be obtained the corresponding relation of Subscriber Number and end points from the call signaling of receiving, thereby need not when needs are followed the tracks of, specially inquire about Softswitch or other higher level equipment, make media gateway to carry out customer call based on Subscriber Number independently and follow the tracks of.
At this end of calling, or when receiving attendant's END instruction, then enter step 540, stop to follow the tracks of this end points.
When media gateway need be exported the tracking results of this end points, then enter step 550, media gateway finds corresponding Subscriber Number according to the Endpoint ID in this tracking results, this Subscriber Number and this tracking results be associated together output to maintenance terminal, show this Subscriber Number and corresponding tracking results by maintenance terminal.Make the attendant directly on media gateway, to check corresponding tracking results, and need not the participation of Softswitch, implement more independently, be not subjected to the influence in geographical position between media gateway and the Softswitch according to Subscriber Number.
What deserves to be mentioned is that in the present embodiment, media gateway can be after stopping tracking, the output tracking result; Perhaps, output tracking result synchronously in the process of following the tracks of, as step 550 '.That is to say that step 550 can be carried out after step 540, perhaps before step 540, carry out, two kinds of situations all can, but no matter be which kind of situation, output together after all needing this tracking results and Subscriber Number be associated.
The third embodiment of the invention and second execution mode are roughly the same, and its difference is, in second execution mode, give tacit consent to this Softswitch and its down all media gateway all support expansion to call signaling; And in the present embodiment, be not that all media gateway are all supported this expansion, need in advance Softswitch to be configured, appointment need be carried Subscriber Number in the call signaling that sends media gateway, that is to say prenotice which media gateway support call signaling expansion of Softswitch.Specifically as shown in Figure 6.
In step 610, the configuration personnel can specify the media gateway that needs to send Subscriber Number by the soft switch maintenance terminal when the initial configuration of this Softswitch.
In step 620, the attendant disposes trace command by maintenance terminal in advance on this media gateway, comprises the Subscriber Number that at least one need be followed the tracks of in this trace command.
After the configuration of finishing Softswitch and media gateway, then enter step 630, when calling out initiation, Softswitch sends call signaling to media gateway, if this media gateway belongs to the media gateway of appointment in the step 610, then Softswitch carries the Subscriber Number of this calling in this call signaling, if this media gateway does not belong to the media gateway of appointment in the step 610, then Softswitch only issues common call signaling, do not carry the Subscriber Number of this calling in this call signaling, its signaling format is with expansion is preceding not identical.Because only in the call signaling of the media gateway that sends to step 610 appointment, carry the Subscriber Number of calling, so media gateway for the expansion of supported protocol not, normal receipt of call signaling does not influence existing call flow yet, with prior art favorable compatibility is arranged.
For the media gateway of supported protocol expansion, it receives identical in operation and second execution mode after signaling, that is to say, step 640 afterwards is identical in to step 660 and step 530 to step 550, does not repeat them here.
Four embodiment of the invention relates to a kind of call follow system, comprises Softswitch and media gateway, and Softswitch comprises: the signaling transmitting element, carry the Subscriber Number of this calling in sending to the call signaling of media gateway; Media gateway comprises: the record cell of corresponding relation that writes down the end points of this Subscriber Number and this calling; Receive the receiving element of trace command; From this corresponding relation, find the unit of searching of corresponding end points according to the Subscriber Number in this trace command; The tracking cell that this end points is followed the tracks of.Because media gateway only may be when Subscriber Number makes a call, just may follow the tracks of it, and in a single day Subscriber Number makes a call, Softswitch will be when sending call signaling carries its call number and issues, media gateway can be known the relation between Subscriber Number and the end points immediately, therefore when needs are followed the tracks of, can find the end points of the Subscriber Number correspondence that needs tracking easily, and need not to inquire about to Softswitch or other higher level equipment, make media gateway to carry out customer call based on Subscriber Number independently and follow the tracks of.This media gateway also comprises: at output tracking as a result the time, find the unit of corresponding Subscriber Number according to the Endpoint ID in this tracking results, this unit can be the above-mentioned unit of searching, and also can be included in the output unit; This output unit is used for this Subscriber Number and this tracking results are associated together output.Make the attendant directly on media gateway, to check corresponding tracking results, and need not the participation of Softswitch, implement more independently, be not subjected to the influence in geographical position between media gateway and the Softswitch according to Subscriber Number.
Wherein, media gateway can be recorded in the corresponding relation of Subscriber Number and call endpoints in the daily record, makes no matter to be need follow the tracks of the time or when needing output tracking as a result, all can be easy-to-look-up, can not lose.
In order in call signaling, to carry Subscriber Number, can in call signaling, define a call number expanding packet, by this call number expanding packet transmission user number, this call number expanding packet can be defined in the endpoint status descriptor of call signaling.This call signaling can be the ADD order, and the Subscriber Number that carries in the call signaling can be rear subscriber number and/or called number.
In this call follow system, also comprise: the soft switch service equipment, be used in advance this Softswitch being configured, specify the media gateway that needs to send Subscriber Number; This signaling transmitting element only carries the Subscriber Number of this calling in the call signaling of the media gateway that sends to this appointment.Thereby can the Autonomous Control tracking, even not being supported in, some media gateway do not carry Subscriber Number in the call signaling, can not make a mistake better compatible with prior art yet.
In this call follow system, also comprise: on media gateway, dispose the equipment of trace command in advance, in this trace command, comprise the Subscriber Number that at least one need be followed the tracks of; Corresponding, this media gateway also comprises: when receiving this call signaling, contrast the Subscriber Number in this trace command and the unit of the Subscriber Number in this call signaling; If the Subscriber Number in this call signaling is included in the Subscriber Number of trace command, the unit that the end points of the Subscriber Number correspondence in this call signaling is followed the tracks of then.
In sum, in the embodiments of the present invention, Softswitch carries the Subscriber Number of this calling in sending to the call signaling of media gateway, and this media gateway writes down the corresponding relation of the end points of this Subscriber Number and this calling; This media gateway finds corresponding end points according to the Subscriber Number in this trace command from corresponding relation when receiving trace command, this end points is followed the tracks of.Make to need not specially to inquire about Softswitch, just can solve can't be corresponding between the end points of Subscriber Number and media gateway identification in the trace command problem, make media gateway to carry out the customer call tracking based on Subscriber Number independently.
