Step 51:After stopping the order measuring of survey crew's transmission is received when measuring originating end, measurement originating end sends deactivation to measurement opposite end and asked, and deactivation request is carried in GTPU message.
Step 52:Measurement opposite end is received after deactivation request, stops sending BR frames, while deactivating response to measurement originating end feedback.
Fig. 6 is the method flow schematic diagram of the deactivation situation of flow second in the embodiment of the present invention, and the present embodiment does not have the situation of feedback information for measurement opposite end.Referring to Fig. 6, including：
Step 61:Measure originating end and send deactivation request to measurement opposite end, while starting timer.Step 62:Within the time that timer is set, when measurement originating end does not receive the feedback information of measurement opposite end, when the time set in timer reaches, measurement originating end sends to measurement opposite end deactivate request again.
Step 63:The flow of repeat step 62 reaches transmission times set in advance until the number of times that measurement originating end sends deactivation request. Step 64:Within the time that timer is set, when measurement originating end does not receive the feedback information of measurement opposite end still, measurement originating end, which is terminated, sends FM frames, discharges resource, terminates measurement.
It is, of course, understood that deactivating request several times when measurement originating end is sent, when measurement opposite end can respond deactivation request, the follow-up process that just can be deactivated using the measurement opposite end Normal Feedback shown in Fig. 5 after response is handled.

The PM frames of the present embodiment can use single GTPU tunnels to carry, or be carried on tested Business Stream in identical GTPU tunnels.Assuming that individually the TEID in the GTPU tunnels of carrying PM frames is 00780522, then can use the tunnel carrying of TEID values mark is PM frames.
It is above-mentioned to be described using measuring originating end as executive agent, then perform following steps for measurement opposite end：
S02:Opposite end is measured to receive the traffic identifier of tested Business Stream of the carrying of measurement originating end transmission in GTPU message and send information；
S03:Opposite end is measured at least one measured in following two of originating end transmission carrying in GTPU message：One is measurement result, another is receive information and sends information, the receive information is measures the receive information for the tested Business Stream that opposite end is obtained according to the traffic identifier, and the measurement result obtains measurement result according to receive information for measurement opposite end with information calculating is sent.
It can further include the step in activation process：
S00:Measure opposite end and receive the activation request that measurement originating end is sent, the activation request is carried in the payload of GTPU message, or is carried in the heading of GTPU message；
S01 :Opposite end is measured to measurement originating end feedback activation response, the activation response is carried in the payload of GTPU message, or carry in the heading of GTPU message, when measuring opposite end satisfaction activation request, the activation response representation is activated successfully, when measurement opposite end can not meet activation request message, the activation response representation activation failure.
It can further include the step deactivated in flow：
S04:Measure opposite end and receive the deactivation request for measuring originating end transmission, it is described to deactivate request carrying In the payload of GTPU message, or carry in the heading of GTPU message；
S05:Measurement opposite end deactivates response to measurement originating end feedback, and the deactivation response, which is carried, to exist
In the payload of GTPU message, or carry in the heading of GTPU message.
Above-mentioned that measuring method is described, the method for the embodiment of the present invention can apply to following scene：
The system structure diagram for the first scene that Fig. 7 applies for the method for the embodiment of the present invention, the present embodiment is WCDMA（Wideband Code Division Multiple Access, WCDMA) system, no Xian Wang Network controllers（Radio Network Controller, RNC) 71 and gateway general grouping service wireless（General Packet Radio Service, GPRS) supporting node（Gateway GPRS Supporting Node, GGSN)/Serving GPRS Support Node（ Serving GPRS Supporting Node:SGSN) between 72 IP PM implement scene, for RNC, RNC → GGSN/SGSN is to be preceding to GGSN/SGSN → RNC is backward.Two-way simultaneous includes above-mentioned two direction.
So that RNC is PM measurement originating ends as an example, using the method for the embodiment of the present invention, RNC can initiate forward, backward and two-way IP PM.Time delay, shake, Lost bag rates being respectively completed in RNC → GGSN/SGSN, GGSN/SGSN → RNC and both direction etc. is measured, and input parameter is provided for RNC stream control and access control.
During forward direction PM, RNC can periodically send FM frames, inform bag number, byte number and the FM delivery time that GGSN/SGSN local terminals are sent etc..GGSN/SGSN is received after FM, at the time of minute book end receives FM frames, the bag number that local terminal can be received, byte number, at the time of receive FM frames and at the time of sending BR frames informs RNC by BR frames.In local terminal Wan Cheng Lost bags rate, One Way Delay He the calculating of Lost byte numbers RNC can also be informed result of calculation and at the time of sending BR frames.：RNC is received after BR frames, according to the information of BR frame ins, finally gives the IP Wang Network performances such as time delay, shake, Lost bag rates, is used as the input parameter of stream control and access control.
Fig. 8 is the structural representation of the protocol stack used in the embodiment of the present invention.Fig. 7 and following Fig. 9,10 can use the protocol stack shown in Fig. 8.
The system structure diagram for the second scene that Fig. 9 applies for the method for the embodiment of the present invention, this implementation Example be Long Term Evolution (Long Term Evolution, LTE) system in, evolution base station (eNodeB) 91 and gateway（Serving Gateway, SGW) IP PM between 92 implement scene, be the interfaces of S 1 between eNodeB and SGW, for eNodeB, eNodeB → SGW is to be preceding to SGW → eNodeB is backward.Two-way simultaneous includes above-mentioned two direction.
The system structure diagram for the 3rd scene that Figure 10 applies for the method for the embodiment of the present invention, the present embodiment is in LTE system, the implement scene of IP PM between first eNodeB 101 and the 2nd eNodeB 102, it is X2 interface between first eNodeB and the 2nd eNodeB, for the first eNodeB, the eNodeB of first eNodeB → the 2nd for it is preceding to the eNodeB of, the 2nd eNodeB → the first be backward.Two-way simultaneous includes above-mentioned two direction.
In the above-described embodiments, by the way that FM frames, BR frames, the carrying of activation/deactivation frame can be realized into the IP Wang Network performance measurements based on GTPU in GTPU message.What deserves to be explained is, the overall plan of the embodiment of the present invention is：The FM frames carried in GTPU message are sent from measurement originating end to measurement opposite end, BR frame of the carrying sent by reception measurement opposite end in GTPU message afterwards, according to the metrical information, obtains IP Wang Network performances.It can be seen that, it is possible to achieve IPPM Wang Network performance measurements are carried out in measurement originating end and measurement opposite end, intermediate node is not related to measurement>Text carries out the processing such as understanding, and is also indifferent to the type of intermediate node, it is achieved thereby that IPPM nets Network performance measurements end to end.
The metrical information returned by measuring opposite end can be specific measurement result, or send information and receive information, measurement originating end is directly obtained measurement result or need calculating to obtain measurement result, realize the flexibility for obtaining measurement result mode.
