Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method and device that improves reporting reliability of monitor user interface data.
Background technology
Lawful Interception, Lawful Interception, be called Legal Interception again, be meant under legally empowered prerequisite, state security organization, the mechanism of the activity of the intercepted user in the application-specific on communication system or the communication system being intercepted as departments such as security bureau, police office.For for simplicity, the follow-up Lawful Interception of this paper abbreviates monitoring as.
The logical network model of monitoring system is referring to Fig. 1.Logical network model shown in Figure 1 is by listening center, motoring gateway, and network element three parts are formed.
Wherein network element is the communication apparatus that service is provided for the user, such as, the MSC Server of circuit domain (mobile services switching centre server)/MGW (media gateway) in stored-program control exchange in the fixed telecommunication network, the mobile communication network, and the SGSN of packet domain (Serving GPRS Support Node)/GGSN (Gateway GPRS Support Node) etc.
Listening center is that state security organization issues snoop command, and receives the entity of the intercept target relevant information that the network equipment reports.
Can introduce motoring gateway between listening center and network element, its effect is adaptive and the difference of the monitoring interface of shielding listening center and network element, simplifies the realization of listening center and network element.
At present, the target relevant information that listening center is paid close attention to is divided into two classes: a class is a control messages, comprises that the targeted customer registers, moves (only in the mobile network), the signaling message in the flow processs such as foundation/release session in network; Another kind of is user face data, be meant that the targeted customer is when using Communications service, the user face data that in service conversation, transmits, such as the IP packet that the audio data stream of user when making a phone call, user transmit when inserting internet and between the email server, WEB server, fax etc.
The flow process of monitoring based on Fig. 1 is as follows:
1, listening center issues a monitoring task by the H1 interface to motoring gateway, has carried by the sign of intercept target information such as the type that monitored data reports (only need report control messages/need report control messages and data-message simultaneously) in the message;
2, motoring gateway is issued to corresponding net element by the X1_1 interface with the monitoring task, has carried by the sign of intercept target information such as the type that monitored data reports (only need report control messages/need report control messages and data-message simultaneously) in the message;
3, when the signaling activity-triggered of intercept target during the incident of regulation, network element reports corresponding control messages by X2 interface to motoring gateway, motoring gateway by the H2 interface to issue the monitoring task listening center report;
When intercept target transmits user face data, if motoring gateway requires the user face data of reported by network elements target, gateway reports corresponding user face data by the X3 interface to motoring gateway, motoring gateway by the H3 interface to issue the monitoring task listening center report.
Motoring gateway is not essential in the specific implementation, when not disposing motoring gateway, when listening center directly is connected with network element, can be considered as H interface and the X interface is unified.Description is that example describes with deployment gateway shown in Figure 1 all.
The prior art relevant with the present invention is as described below:
Present communication network is divided into circuit domain and two parts of packet domain, and circuit domain is mainly carried traditional Circuit-switched speech business, and emerging packet domain then provides the Packet Service based on the IP exchange, as internet visit, WAP or the like.The monitor function of circuit domain and packet domain is independently, promptly if the activity of a complete target of monitoring, need listening center to issue the monitoring task to the network element of circuit domain and packet domain respectively by motoring gateway, the circuit domain network element is responsible for reporting the speech business information of intercept target, and grouping domain network element is responsible for reporting the Packet Service information of intercept target.
In packet domain, motoring gateway can carry following information in message when issuing the monitoring task to network element:
The sign of intercept target;
The type of monitoring task (only report control messages, or report control messages and user face data simultaneously);
Motoring gateway receives the address information of the control messages of this intercept target of reported by network elements;
Motoring gateway receives the address information (while monitor user interface data if desired) of the user face data of this intercept target of reported by network elements;
In specific implementation, if motoring gateway has only the address of a unified reception reported by network elements control messages and the address of a unified reception reported by network elements user face data, so also can be when motoring gateway and network element begin to connect, the disposable network element that is handed down to of motoring gateway, perhaps on network element, dispose, no longer need motoring gateway at every turn when network element issues the monitoring task, for each target is specified the address information that reports control messages and user face data separately.
Under prior art, when the targeted customer who is monitored carries out a plurality of service conversations simultaneously, network element is to motoring gateway report of user face data the time, the sign of affiliated service conversation is set for every user face data, the user face data that then these is belonged to a plurality of service conversations is by unified passage, report listening center through motoring gateway, filter out the user face data that belongs to same service conversation by listening center according to the service conversation sign of carrying in the user face data, and recover reduction.
Because the advantage of packet switching, professional (for for simplicity, hereinafter being referred to as speech business) such as the voice of circuit domain carrying, visual telephones also will be carried on the packet domain, compare with the Packet Service of traditional internet class, and speech business has following difference:
1) concerning monitor function, the voice class business is more important than internet class business;
2) bandwidth ratio that takies of speech business is more fixing, usually a few K bits/ second to tens K bits/ seconds, and long data packet is generally little;
3) be reported to the user face data of the speech business of listening center can allow a spot of packet loss, and do not influence the quality of listening center reduction voice substantially;
4) listening center is more responsive to the retardation ratio that the reports tradition internet class business of speech business, when voice call takes place, require to be reported to listening center as early as possible, otherwise situations such as intermittent appears in speech playback meeting;
5) the professional AMR telecom coding technology such as (adaptive multi-rate) that adopt such as voice more, when listening center decoding reduction and speech playback, may need independent equipment to handle, adopt traditional computer technology to get final product more and the user face data of listening center reduction internet business.
In realizing process of the present invention, the inventor finds that after packet domain was introduced in existing speech business, because above-mentioned difference, the user face data of speech business and internet class business mixed the pattern that reports and has following shortcoming at least:
1. owing to have only a passage, do not have the user face data of the speech business of strict demand to need to be reported to motoring gateway yet, increased the network element load, increased the delay that speech business reports simultaneously by reliability protocols such as TCP to the reported data integrality;
2. take place when congested when this passage, the user face data of the speech business of network element buffer memory gets clogged, and can not in time be reported to listening center to reduce and playback, in addition may since the network element buffer queue overflow and be dropped;
3. in listening center one side, owing to have only one to report passage, motoring gateway can only be handled according to the reception order successively to the user face data of a plurality of service conversations of intercept target, can not the priority treatment speech business, and need a preposition module that the user face data of speech business is filtered out the special equipment that just can deliver to tone decoding to handle, increase the load that listening center is handled, also increased the delay that speech business reports.
