Embodiment one
As shown in figure 3, the present embodiment proposes a kind of VOLTE network performance test methods, including：
S10, Signalling exchange script is built according to test scene, the Signalling exchange script includes that the data pre-established are led to
Road and prefabricated media message；
S20, call business is initiated by the data channel by signaling processing module, and notifies medium process module；
S30, the corresponding media message of the call business is handled by medium process module, completes call business
Test；
Wherein, the signaling processing module and the medium process module physical separation.
In the present embodiment, the business that multi-terminal user is simulated by signaling processing module and medium process module, to
The test to VOLTE network performances is completed efficiently at low cost, and autgmentability is higher.
In the present embodiment, client/server namely C/S moulds are based between signaling processing module and medium process module
Formula realizes interconnection, in this way, the mixing traffic model for truly testing various complexity can be approached, while having relatively flexibly
Control ability, and tool is cheap, easy to use, can theoretically realize unlimited dilatation, can be simulated using a small amount of PC machine
The behavior of magnanimity terminal, so as to the performance test of the completion VOLTE whole networks of low cost.
In the present embodiment, the signaling processing module is the signaling processing built using high performance blade server
Machine, the blade server are a kind of servers of veneer kenel, refer to can be inserted in the rack cabinet of calibrated altitude it is multiple
The server unit of cassette is a kind of realization HAHD (High Availability High Density, High Availabitity high density)
Inexpensive server platform, the signaling handler CPU state built by blade server is basicly stable, will not when it is high when it is low,
The Behavior modeling of 80,000 LTE terminals can be achieved, and each medium process module can realize that the message of 30,000 road voice calls is sent,
And different grades of performance requirement can be met by trunking mode, and cluster expansion is theoretically without the upper limit.
In the present embodiment, the pattern detached using signaling, media handling, signaling processing module and medium process module position
In on different physical equipments, interacted by coupling between module, and voluminous media data is shielded by bypass technology
Influence of the message to signaling handler so that all one's effort that signaling processing module can eliminate distractions handles signaling message, optimization side
Case performance promotes treatment effeciency.
As shown in figure 4, in the present embodiment, the step S10 includes：
S11, VOLTE user's registrations are completed using S1 mouthfuls of signaling processes and mobile management entity according to test scene, passed through
4G core networks EPC is established and the data channel of IP multimedia systems IMS interactions；
S12, each to register, user is prefabricated to keep duration for the media message of call business and calling.
In the present embodiment, it is provided with figure configuration interface on the Signalling exchange script, in order to change.
In the present embodiment, by the voice message or video message binary format of the various rates involved in test process
Save as fixed disk file, by build different file content it is implicit realize the message transmission sequence for needing to be related in test process and
Send percentage.
In the present embodiment, S1 mouthfuls are a logic interfacing, are the interfaces from Enodeb to mobile management entity MME,
Middle Enodeb refers to evolved Node B namely EnB, is the title of the base station in LTE network, from any one EnB, Ke Nengyou
Multiple S1-MME logic interfacings are towards EPC；Wherein, VOLTE user's registrations include the registration of the sides EPC and the registration of IMS, are passed through
EPC sets up the data channel of one and IMS domain interaction, then initiates audio call by the channel, works as access success, media
After connection is established, the transmission of respective media message, end of calling are carried out according to the result notice medium process module of media negotiation
When, related data resource is discharged, the simulation of a user behavior (such as calling) is completed.Pass through the superposition to numerous user behaviors
And then performance test of the completion to entire VOLTE core network systems.
In the present embodiment, the test scene is obtained by VOLTE core net tested element systems, according in test scene
The call number (CAPS) per second of establishing of setting determines the rate for initiating Path Setup request, such as 100 times per second, and according to note
Whether the quantity of volume user judges all data channel it has been established that being tested again after having built up.
As shown in figure 5, in the present embodiment, the step S20 includes：
The behavior of terminal and base station is integrated by S21, signaling processing module, converts the interacting message of wireless side to this
Ground scheduling message；The expense of wireless side is eliminated, great amount of terminals user can be simulated to VoLTE whole process performance tests；
S22, call business is initiated by the data channel, timer-triggered scheduler queue is added in the call business
In, being associated with for the call business and data field is then cut off, the data field being released will be answered by subsequent call flow
With；Being added into the release operation of timer-triggered scheduler queue will be invoked automatically after timer expiry, complete the release of corresponding calling
Operation.The CAPS that bigger can be achieved so under same hardware condition improves VOLTE online user's quantity simultaneously；
S23, duration is kept to be sent to medium process module the corresponding media message of the call business and calling.
In the present embodiment, the medium process module includes media sending module and media receiver module, the media
Sending module and the separation of media receiver module physical are put on camouflage to all media messages by using address spoofing technology,
So that receiving terminal deeply convinces the validity of its received data packet, and the media message of opposite end outgoing is drained into what this equipment was specified
Receiving terminal converts the media packet interaction of dual-mode to " either simplex to eliminate the expense that media sending device receives network packet
" pattern improves VoLTE voice user's capacity, improves data service throughput.
As shown in fig. 6, in the present embodiment, the step S30 includes：
The media message is loaded into read-only mode in memory by S31, media sending module, is built transmission pattern, is opened
Packet overtime timer is inspired, is continued and is started and give out a contract for a project process to destination address periodicity sending media message, and is fixed in time-out of giving out a contract for a project
