Abstract
The invention relates to a voice test method for simulating packet loss, delay and jitter under an IMS (Internet protocol multimedia subsystem) large network environment. A computer network tool is commanded by Ping and used for testing whether a specific host can achieve through IP (Internet protocol); and the operation way of the ping is as follows: sending an ICMP (Internet control message protocol) echo to the target host to require grouping, and waiting for receiving an echo response for grouping; and estimating loss grouping rate and grouping roundtrip time by a program according to the time and the success times of response, wherein the packet loss means that, after the ping, some ICMP packets get the responses, and some do not get the responses; the delay means the corresponding time of the ICMP packets from a testing machine to a tested machine after ping; disorder means whether the ICMP data packets respond to the testing machine or not according to the sending order after ping; and after setting up an environment and performing test simulation, network conditions, including the packet loss, the delay and the disorder, can be realized through a defining way.
Description
Technical field
The present invention relates to the combined test method of voice aspect and network facet, relate in particular to the automated voice method of testing of simulation packet loss, delay, shake under the big net environment of IMS.
Background technology
Along with the high speed development of Internet, network application is more and more, and some key businesses of most of enterprises also begin to provide through Internet.The IMS network is that the next generation of commmunication company uses; And IMS arises at the historic moment by means of network facet; Therefore the quality quality for network relies on very much, and for the generation of the delay of network, packet loss, phenomenon such as out of order, a lot of beyond thought problems often appear in voice quality.
The birth of Jitter Buffer technology is also arranged at present; Improvement in order under the bad situation of network foundation, to carry out exactly; A lot of voice manufacturers have also added on this should technology; And be implemented on the voice product separately, still, also there is not extraordinary method to realize at present for the simulation of this environment.
Summary of the invention
The present invention is directed to the tone testing under the big net environment of Simulation with I MS how, the automated voice method of testing of simulation packet loss, delay, shake under the big net environment of IMS is provided, improve voice quality.
The object of the invention is realized through following technical scheme:
The big net environment of IMS is the tone testing method of simulation packet loss, delay, shake down, and characteristics are, and: Ping orders a computer network instrument, and can be used for testing particular host arrive through IP; The function mode of ping is: spread out of an ICMPecho to destination host and require to divide into groups, wait for that receiving the echo response divides into groups; Program is estimated to lose packet rate and is divided into groups the turnaround time by time and the successful number of times of reaction;
Packet loss: be meant that after ping crosses the ICMP bag that has obtains corresponding, the ICMP bag that has does not obtain corresponding;
Postpone: be meant after ping crosses the corresponding time of bag from main survey machine to the ICMP the tested machine;
Out of order: as to be meant after ping crosses whether the ICMP packet is responded to main survey machine according to the order that sends successively;
Behind environmental structure and test simulation, make packet loss, delay, out of order network condition realize through the mode of definition.
Further; The big net environment of above-mentioned IMS is the tone testing method of simulation packet loss, delay, shake down; The IMS server is the call testing server of a Session Initiation Protocol, and first audio call and second audio call all are registered in the IMS server with the Session Initiation Protocol mode; Network analog equipment framework is between IMS server and switch, so all VoPs are all with IP packet form process network analog equipment; In network analog equipment, carry out packet loss, out of order, delayed test; In Session Initiation Protocol, first audio call and second audio call all are registered in the IMS server, when carrying out audio call; The RTP bag all is to carry out transfer through the IMS server; In case therefore network occurs unusually, packet loss, delay, out of order phenomenon occur, and user's perception is very obvious.
Substantive distinguishing features and obvious improvement that technical scheme of the present invention is outstanding are mainly reflected in:
Phenomenons such as the packet loss that real simulation reproducing network of the present invention causes unusually, delay.All tests can be in the good Intranet of network condition, simulate realization in the laboratory.Need not buy the tester of specialty, need not spend the too much time to build the network test environment, the environment framework is simple; Can network environment be carried out the modularization simulation and realize, such as packet loss and delay combine analog, packet loss and out of order combine analog or the like.
Embodiment
The big net environment of IMS is the tone testing method of simulation packet loss, delay, shake down, and Ping orders a computer network instrument, and can be used for testing particular host arrive through IP; The function mode of ping is: spread out of an ICMPecho to destination host and require to divide into groups, wait for that receiving the echo response divides into groups; Program is estimated to lose packet rate and is divided into groups the turnaround time by time and the successful number of times of reaction;
Packet loss: be meant that after ping crosses the ICMP bag that has obtains corresponding, the ICMP bag that has does not obtain corresponding;
Postpone: be meant after ping crosses the corresponding time of bag from main survey machine to the ICMP the tested machine;
Out of order: as to be meant after ping crosses whether the ICMP packet is responded to main survey machine according to the order that sends successively;
Behind environmental structure and test simulation, can so that packet loss, delay, network condition such as out of order realize through the mode of definition.
For example packet loss 5% after 100 ICMP bags send out, has only 95 ICMP bags to obtain responding so, and this packet loss can be configured in 0% ~ 100%;
For example postpone 200ms, after 100 ICMP bags sent out, each bag just obtained responding after having 200ms so, and this delay can be configured in 1ms ~ 2000ms;
For example out of order is 10, after 100 ICMP bags send out, has 10 and contracts out out of order at present phenomenon, this out of order can in 0% ~ 100%, being configured so.
The IMS server is the call testing server of a Session Initiation Protocol, and first audio call and second audio call all are registered in the IMS server with the Session Initiation Protocol mode; Network analog equipment framework is between IMS server and switch, so all VoPs are all with IP packet form process network analog equipment; In network analog equipment, carry out packet loss, out of order, delayed test; In Session Initiation Protocol, first audio call and second audio call all are registered in the IMS server, when carrying out audio call; The RTP bag all is to carry out transfer through the IMS server; In case therefore network occurs unusually, packet loss, delay, out of order phenomenon occur, and user's perception is very obvious.
Phenomenons such as the packet loss that can the real simulation reproducing network causes unusually, delay.All tests can be in the good Intranet of network condition, simulate realization in the laboratory.Need not buy the tester of specialty, need not spend the too much time to build the network test environment, the environment framework is simple; Can network environment be carried out the modularization simulation and realize, such as packet loss and delay combine analog, packet loss and out of order combine analog or the like.
What need understand is: the above only is a preferred implementation of the present invention; For those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
