Step 404：First server is obtained respectively between each second server at least one second server Communication delay, obtain at least one communication delay.

During access server each due to terminal, the first server and second server of selection may be different, so, eventually When holding each access server, first server is required for according to the communication delay between at least two server, obtains the The one server communication delay between each second server at least one second server respectively.

Wherein, the communication delay between at least two server is fixed, it is possible to obtain at least two clothes in advance Communication delay between business device, and be stored in each server.It, can after first server and second server has been selected With the communication delay between at least two servers according to storage, determine the first server respectively with this at least one second The communication delay between each second server in server, obtains at least one communication delay.It can also be terminal access During server, which obtains it between each second server at least one second server in real time Communication delay.The application is not specifically limited this.

Wherein, itself and at least one second service are obtained respectively in real time when first server is in terminal access server During communication delay between each second server in device, which obtains itself and at least one second server In each second server between the method for communication delay include a variety of, lift an a simplest example, the first server When can send a latency message at least one second server simultaneously, and record the transmission for sending the latency message Between；When at least one second server receives the latency message, a time delay is replied to the first server immediately and rung It should；When the first server receives the DELAY RESPONSE that each second server is sent, record receives the DELAY RESPONSE respectively Receiving time, respectively by the half of the time interval between the sending time and receiving time determine the first server with this Communication delay between two servers.

Wherein, each second server corresponds to a communication delay, and communication delay is first server and the second clothes Time between business device needed for transmission message.

For example, include 4 second servers, respectively second server 1, second server 2, second server in system 3 and second server 4, first server to the time of the 4 second server transmission delay message be 10:13:03.This first The receiving time that server receives the DELAY RESPONSE of the transmission of second server 1 is 10:13:04, it receives second server 2 and sends out The receiving time for the DELAY RESPONSE sent is 10:13:05, the receiving time of DELAY RESPONSE for receiving the transmission of second server 3 is 10:13:07, the receiving time for receiving the DELAY RESPONSE of the transmission of second server 4 is 10:13:09.Second service will be received The receiving time 10 for the DELAY RESPONSE that device 1 is sent:13:04 with time 10 of transmission delay message:13:Time interval between 03 The half 0.5s of 1s is determined as the communication delay between first server and second server 1；Second server 2 will be received to send out The receiving time 10 for the DELAY RESPONSE sent:13:05 with time 10 of transmission delay message:13:Time interval 2s's between 03 Half 1s is determined as the communication delay between first server and second server 2；By receive that second server 3 sends when Prolong the receiving time 10 of response:13:07 with time 10 of transmission delay message:13:The half 2s of time interval 4s between 03 The communication delay being determined as between first server and second server 3；The DELAY RESPONSE for second server 4 will be received sending Receiving time 10:13:09 with time 10 of transmission delay message:13:The half 3s of time interval 6s between 03 is determined as Communication delay between first server and second server 4.

Step 405：First server selects maximum communication delay from least one communication delay, according to maximum Communication delay determines delay time.

Specifically, which is compared by first server respectively, from during at least one communication The maximum communication delay of Yanzhong selection, delay time is determined according to maximum communication delay.

For example, first server selects maximum communication delay 3s from 4 communication delay 0.5s, 1s, 2s and 3s, according to Maximum communication delay 3s determines delay time.

Wherein, the operation for determining delay time according to maximum communication time delay is specifically as follows：Maximum communication delay is true It is set to delay time.Alternatively, maximum communication delay is added with preset time interval, delay time is obtained.

If the operation for determining delay time according to maximum communication time delay is：By maximum communication delay with it is preset when Between be spaced and be added, obtain delay time.For example, preset time interval is 1s, then by maximum communication delay 3s and in advance If time interval 1s be added, obtain delay time as 4s.

Wherein, preset time interval is set in advance, and preset time interval cannot be too big.

Wherein, step 404 and step 405 can be performed in any time between step 401 and step 406, that is, It says, step 404 and step 405 can perform before step 402, can also perform after step 403, can also be in step Perform, can also be performed simultaneously with step 402 or step 403 between 402 and step 403, the embodiment of the present invention with step 404 and Step 405 illustrates for performing after step 403.

It should be added that in embodiments of the present invention, server can be selected from least one communication delay Maximum communication delay is selected, delay time is determined according to maximum communication delay, certainly, network administrator can also be according to common sense Estimate with experience and the delay time is configured.Preferably, which can be from least one communication delay for server The maximum communication delay of middle selection, determines according to maximum communication delay.

Step 406：First server will receive the first connection and establish the time of inquiry message and delay time progress It is added, obtains sending and invite the time.

Wherein, the time for receiving the first connection foundation inquiry message is a moment, and delay time is a time Interval, so, will receive the first connection establish inquiry message time be added with the delay time after, obtained hair It is also a moment to send and invite the time.

For example, the time 10 that first server will receive the first connection foundation inquiry message:13:02 with the delay time 4s is added, and it is 10 to obtain transmission and invite the time:13:06.

Step 407：First server establishes addition transmission in inquiry message in the first connection and invites the time, obtains the second company Foundation inquiry message is connect, and inquiry message is established into the second connection and is sent at least one second server.

Due to factors etc. such as the distance between first server and at least one second server and Network status, It is different so as to cause the communication delay between the first server and at least one second server, so in order to overcome first Communication delay between server and at least one second server, ensures the first server and at least one second service Device establishes invitation message to terminal replies connection simultaneously, which establishes in inquiry message in the first connection and add hair It send and invites the time, transmission is made to invite before the time reaches, all second servers, which receive the second connection, to be established inquiry and disappears Breath, and can make to send to connect to establish simultaneously to the terminal when transmission invites the time to reach there are the server of idling-resource to invite It please message.

In embodiments of the present invention, the second connection can be established inquiry message and be sent to all second by first server Server, can also from all second servers selected section second server, by second connection establish inquiry message hair Give the part second server of selection.

When first server from least one second server selected section second server, and by second connection establish When inquiry message is sent to the part second server of selection, first server selected section from least one second server The concrete operations of second server can be：First server is according to the IP address of the terminal, from stored public network address library Middle to obtain corresponding geographical location, which includes the correspondence between IP address and geographical location；First service Device determines the geographic range where the geographical location of the terminal according to the geographical location of acquisition；From stored geographic range with In correspondence between server ip address, the geographic range where obtaining the geographical location of the terminal is corresponding at least one Server ip address；The corresponding server of at least one server ip address of acquisition is determined as the part second service of selection Device.

Wherein, the correspondence between the geographic range and server ip address that are stored in first server can be a pair of More relationships, i.e. a geographic range can correspond at least one server ip address, that is to say, that there may be at least one Server is responsible for the communication of a geographic range.For example, China is deployed with three servers in total, due to the network of China More independent, terminal of the physical location in Chinese range must be that time delay is shortest using the server of China.It is whole simultaneously The server ip address of a China will not frequently occur change or mistakes and omissions (but be specific to different provinces and cities may just can not essence It is really corresponding).Therefore, by this one-to-many mapping relations, inquiry message is established when first server receives the first connection Afterwards, first determine whether that the IP address of the terminal is located at China, then the second connection only is established inquiry message is sent to China Three servers, the server without being transmitted to European Area or America area.

It should be added that public network address library and geographic range and service can be configured in first server in advance Correspondence between device IP address.

Wherein, it establishes in inquiry message to add to send in the first connection and invite the time, generation the second connection foundation inquiry disappears After breath, the second connection, which is established the IP address that the terminal is at least carried in inquiry message and sent, invites the time.

Step 408：When at least one second server, which receives the second connection, establishes inquiry message, invited sending When time reaches, first server and at least one second server send to the terminal all in accordance with the IP address of the terminal and connect It connects and establishes invitation message.

Preferably, in embodiments of the present invention, disappear when at least one second server receives the second connection foundation inquiry During breath, for each second server at least one second server, whether which can determine itself There are idling-resource, if there are idling-resources, when sending the arrival of invitation time, the second server for the second server Can connection be sent to the terminal according to the IP address of the terminal and establish invitation message.And first server can also determine itself With the presence or absence of idling-resource, if there are idling-resources, when sending the arrival of invitation time, first server for first server Can connection be sent to the terminal according to the IP address of the terminal and establish invitation message.

Optionally, it is established in inquiry message due to the first connection and also carries the resource size established needed for connection, so the Two connections establish in inquiry message and also carry the resource size established needed for connection；Accordingly at least one second clothes The each second server being engaged in device is invited when the second server sends connection foundation according to the IP address of the terminal to the terminal Please be before message, which obtains the idling-resource size in second server, compares the sky in the second server Not busy resource size is with establishing the resource size needed for connection；If the idling-resource size in the second server is greater than or equal to The resource size needed for connection is established, then the second server is determined as to the server there are idling-resource.When by this second Server is determined as after the server there are idling-resource, and when sending the arrival of invitation time, which can root Connection is sent to the terminal establish invitation message according to the IP address of the terminal.

Optionally, when first server according to the IP address of the terminal to the terminal send connection establish invitation message it Before, which can also obtain the idling-resource size in first server, compare the idle money in first server Source size is with establishing the resource size needed for connection；It is established if the idling-resource size in the first server is greater than or equal to The first server, then is determined as the server there are idling-resource by the resource size needed for connection.When by the first service Device is determined as after the server there are idling-resource, and when sending the arrival of invitation time, which can also basis The IP address of the terminal sends connection to the terminal and establishes invitation message.

Further, after the server there are idling-resource is determined, the server there are idling-resource can be with Resource size according to needed for establishing connection reserves the resource established needed for connection for the terminal.I.e. when first server exists During idling-resource, first server can be that the terminal reserves the resource established needed for connection, when second server is in the presence of idle During resource, second server can be that the terminal reserves the resource established needed for connection.

Wherein, it after reserving the resource established needed for connection for the terminal, avoids and accesses the server in the terminal In the process, the resource is occupied by other terminals.When the terminal accesses the server, which can smoothly access this Server, and the resource in the server provides service for the terminal enough.

Further, for each second server at least one second server, when the second server does not have During available free resource, which abandons second connection and establishes inquiry message, without any processing.

It should be added that in embodiments of the present invention, can first server be ensured with usage time synchronous protocol Time synchronization between at least one second server, time synchronization protocol are selected according to requirement of the practical application to precision It selects, can include but is not limited to the following two kinds agreement, including：

The first, NTP (Network Time Protocol, network event synchronous protocol), precision can in LAN Up to 0.lms, its local precision most of on the internet can reach 1-50ms.

Secondth, PTP (Precision Time Protocol, accurate clock synchronization protocol), PTP is known as IEEE1588, Referred to as 1588.1588 points are two versions of 1588v1 and 1588v2, and 1588v1 can only achieve the time synchronization essence of sub- Millisecond Degree, and 1588v2 can reach submicrosecond grade synchronization accuracy.
