Method and device for determining transmission link

Technical Field

The present invention relates to the field of internet technologies, and in particular, to a method and an apparatus for determining a transmission link.

Background

With the development of internet technology, there are two main ways of voice communication: one is voice communication based on PSTN (public switched Telephone Network) networks, e.g., communication services provided by different operators; another is voice communication based on an IP (Internet Protocol) network, for example, based on communication services provided by various instant applications. Because the users of the PSTN network and the IP network are distributed in different areas, in order to enable the users in different areas and different networks to communicate more smoothly, the PSTN network and the IP network are respectively provided with a plurality of servers in different areas, and a plurality of transmission links can be adopted for transmission in the process of realizing the communication from a calling end to a receiving end. Since the performance of different servers is different and the transmission quality of the transmission link determined by different servers is also different, in order to provide a voice communication service that can be provided to users well, it is necessary to determine the transmission link and the transit server node.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

VOIP (Voice over Internet Protocol) is a new service for Voice communication using Internet technology or network technology. VOIP is gaining favor to more and more users because it can transmit voice, fax, video, etc. over IP networks for free.

In the scenario of communicating with the PSTN network in the cross-IP network, because the transmission mechanisms of the IP network and the PSTN network are different, the VOIP system shown in fig. 1 is difficult to acquire comprehensive and accurate data on the PSTN network side. In order to improve the communication quality, fig. 2 shows a background architecture diagram of a determination system of a transmission link, as can be seen from fig. 2, the system includes a calling end, a VOIP platform, a plurality of transit service platforms, and a receiving end.

The relay service platform is located in the PSTN network, and an SIP (session initiation Protocol) server cluster, a media stream server cluster, and the like are erected on the relay service platform.

The dispatching server stores the SIP server list on the VOIP platform, the SIP server list on the transfer service platform and the media stream server list on the VOIP platform in advance, and the media stream servers on the transfer service platform are dispersed in the floor machine rooms of each operator, so the media stream server list on the transfer service platform is not stored in the dispatching server. The scheduling server can schedule the transit service platform, the SIP server on the VOIP platform and the media stream server on the VOIP platform.

The receiving end is located in the PSTN network, and can communicate with the calling end located in the IP network through the PSTN network, and the receiving end can be a smart phone, a fixed telephone, and the like.

Based on the architecture diagram of the transmission link determining system shown in fig. 2, an embodiment of the present invention provides a transmission link determining method, where the method is applied in a scenario where a first terminal in an IP network communicates with a second terminal in a PSTN network, where the first terminal is a calling end, the second terminal is a receiving end, and a scheduling server executes the method as an example, with reference to fig. 4, a method flow provided by the embodiment of the present invention includes:

401. when a communication request sent by a first terminal is received, a scheduling server acquires first performance parameters of a plurality of first transit service platforms in a PSTN network.

When a first terminal side user wants to carry out voice communication with a second terminal located in a PSTN network through an IP network free of charge, the first terminal side user can send a communication request to a VOIP platform through any voice communication application installed in the first terminal, and the communication request at least carries a user identifier of the first user side, an identifier of the second terminal and the like. And the VOIP platform sends the received communication request to the scheduling server in the platform. When a communication request sent by a first terminal is received, the scheduling server obtains first performance parameters of a plurality of first transit service platforms according to the obtained first performance parameters, and the first performance parameters are obtained by the scheduling server through calculation according to the latest statistical data of the first transit service platforms.

It should be noted that, since the present embodiment relates to multiple transit service platforms, in order to facilitate distinguishing different transit service platforms, in the present embodiment, an unscreened transit service platform in the determination system of the transmission link is referred to as a first transit service platform, a transit service platform screened from a plurality of first transit service platforms according to the first performance parameter is referred to as a second transit service platform, a transit service platform screened from a plurality of second transit service platforms is referred to as a target transit service platform, and the first transit service platform, the second transit service platform, and the target transit service platform are only for distinguishing and do not represent important orders of different transit service platforms.

In this embodiment, the first performance parameter includes a network connection rate, a connection success rate, a network delay, a network packet loss rate, an answering rate, an excessively short call duration rate, a normal hang-up rate, and a spare rate of the first relay platform. The spare rate comprises the spare rate of each SIP server and each media stream server on the VOIP side and the spare rate of each SIP server and each media stream server on the PSTN side. Among the first performance parameters, the network connection rate, the connection success rate, the network delay, the network packet loss rate and the VOIP side vacancy rate are VOIP side parameters, and the answering rate, the too short call duration rate, the normal hang-up rate and the PSTN side vacancy rate are PSTN side parameters.

The network connectivity rate (conn _ rate) is calculated according to the SIP signaling (REQ _ CNT) sent to each first transit service platform and the corresponding acknowledgement number (ACK _ CNT) within a statistical time (e.g., 5 minutes, 10 minutes, 15 minutes, etc.), and may be represented as (ACK _ CNT/REQ _ CNT) × 100%. The network connection rate is used for monitoring the network connection condition from each SIP server on the VOIP platform to the first transit service platform.

The connection success rate (conn _ SUCC _ rate) is calculated according to the SIP signaling (REQ _ CNT) sent to one SIP server in the first transit service platform and the response success number (SUCC _ CNT) of the SIP server within a statistical time (e.g., 5 minutes, 10 minutes, 15 minutes, etc.), and may be represented as (SUCC _ CNT/REQ _ CNT) × 100%.

The network delay (rep _ relay) is calculated according to the network delays of the media stream server on the VOIP platform and the media stream server on the first transit service platform within the statistical time (such as 5 minutes, 10 minutes, 15 minutes, etc.), and the network delays are reported to the scheduling server by the media stream server on the VOIP platform. The network delay is used for monitoring the call quality between the media stream server on the VOIP platform and the media stream server on the first transit service platform.

The network packet loss rate (rep _ loss) is calculated according to the network packet loss rates of the media stream server on the VOIP platform and the media stream server on the first transit service platform within the statistical time (e.g., 5 minutes, 10 minutes, 15 minutes, etc.), and the network packet loss rate is reported to the scheduling server by the media stream server on the VOIP platform. The network delay is used for monitoring the conversation quality between the media stream server on the VOIP platform and the media stream server on the first transit service platform.

The free rate (free _ rate) of the VOIP side includes the free rate of the SIP server and the free rate of the media streaming server. Usually, each SIP server and media stream server on the VOIP platform have their own concurrent numbers, the concurrent numbers of the VOIP side are reported to the scheduling server by each SIP server and media stream server on the VOIP platform periodically, and the scheduling server calculates the vacancy rate of each SIP server according to the concurrent numbers of each SIP server and the data volume of the currently transmitted signaling data; and the scheduling server calculates the vacancy rate of each media stream server according to the concurrency number of each media stream server and the data volume of the currently transmitted voice data.

The receiving rate (accept _ rate) is calculated according to the number of initiated PSTN CALL requests (CALL _ REQ) and the number of users normally receiving in the initiated PSTN CALL requests (APT _ CNT) within a statistical time (e.g., 5 minutes, 10 minutes, 15 minutes, etc.). The hearing rate may represent (APT _ CNT/CALL _ REQ) 100%. The answering rate is used for monitoring whether the PSTN line of the first transfer service platform is normal or not, and if the answering rate is stable within a certain range, the first transfer service platform can be determined that the PSTN network is normal.

The SHORT _ rate is calculated according to the number of CALLs (SHORT _ CNT) with the CALL duration less than the preset threshold in the normally answered CALL (CALL _ CNT) and the normally answered CALL (CALL _ CNT) within the statistical time (such as 1 day, 3 days, 5 days, etc.). The CALL duration too SHORT rate may be expressed as (SHORT _ CNT/CALL _ CNT) 100%. The too short call duration rate is used for monitoring whether the PSTN line of the first transfer service platform is normal or not, and if the too short call duration rate is stable within a certain range, the PSTN network can be determined to be normal.

The NORMAL CALL hang-up rate (NORMAL _ rate) is calculated according to the number of CALLs in the NORMAL CALL (CALL _ CNT) and the NORMAL hang-up (HANGUP _ NORMAL _ CNT) in the NORMAL CALL (CALL _ CNT) within the statistical time (e.g. 5 minutes, 10 minutes, 15 minutes, etc.). The NORMAL dropped CALL rate can be expressed as (HANGUP _ NORMAL _ CNT/CALL _ CNT) 100%. The normal hanging-up rate of the call is used for monitoring whether the PSTN line of the first transit service platform is normal, and if the normal hanging-up rate of the call is 100%, the PSTN line can be determined to be normal.

The free rate (free _ rate) on the PSTN side is calculated by the scheduling server. Because each first transit service platform has the maximum capacity of the PSTN line, and each SIP server on each first transit service platform also has the maximum concurrency number of the SIP server, the vacancy rate of the PSTN side has two dimensions, wherein one dimension is the vacancy rate of each first transit service platform, and the other dimension is the vacancy rate of each SIP server.

Because each first transit service platform is provided with a plurality of SIP servers and a plurality of media stream servers, when the first performance parameter of any first transit service platform is obtained, the first performance parameter of each SIP server and each media stream server on the first transit service platform can be obtained, and the average value of the first performance parameter is calculated according to the first performance parameter of each SIP server and each media stream server on the first transit service platform and serves as the first performance parameter of the first transit service platform.

402. And the dispatching server determines a target transfer service platform from the plurality of first transfer service platforms according to the first performance parameters of the plurality of first transfer service platforms.

When the step is implemented specifically, the following modes 4021-4024 can be adopted:

4021. the scheduling server determines a plurality of second transit service platforms from the plurality of first transit service platforms according to the first performance parameters of the plurality of first transit service platforms.

After the first performance parameters of the multiple first transit service platforms are acquired, the scheduling server compares the first performance parameters of each first transit service platform with a first threshold, and if the network connection rate, the connection success rate, the network delay, the network packet loss rate, the answering rate, the too short call time rate, the normal hang-up rate and the vacancy rate of any one first transit service platform are all greater than the first threshold, the first transit service platform is used as a second transit service platform; and if any one of the network communication rate, the connection success rate, the network delay, the network packet loss rate, the answering rate, the too short call duration rate, the normal hang-up rate and the vacancy rate of any one of the first transit service platforms is smaller than a first threshold value, the first transit service platform is excluded. The first threshold is set by the scheduling server according to the historical data, and may be 60%, 70%, 90%, and the like, and the size of the first threshold is not specifically limited in this embodiment.

4022. The dispatch server calculates actual call quality values of the plurality of second transit service platforms.

When the dispatch server calculates the actual call quality values of the plurality of second transit service platforms, the dispatch server may adopt the following steps 40221 to 40223:

40221. for any second transit service platform, the scheduling server applies the following formula to calculate the reference call quality value of the second transit service platform:

Q＝W*0.6^a*0.95^b*c*d*e*f*g

wherein, Q represents a reference call quality value of the second transit service platform, W represents a designated weight value which can be set by a technician, a represents a network packet loss rate, b represents a network delay, c represents a network connection rate, d represents a connection power, e represents an answering rate, f represents an excessively short call duration rate, and g represents a normal hang-up rate.

In this embodiment, the vacancy rate of the second transit service platform affects the actual call quality value of the second transit service platform, and when the vacancy rate of the second transit service platform is greater than the second threshold, the actual call quality value of the second transit service platform is calculated through step 40222; when the vacancy rate of the second transit service platform is smaller than the second threshold, the actual call quality value of the second transit service platform is calculated through step 40223. The second threshold is set by the scheduling server according to the historical data, and the second threshold may be 10%, 30%, 40%, and the like, and the size of the second threshold is not specifically limited in this embodiment.

40222. And if the vacancy rate of the second transit service platform is larger than a second threshold value, the dispatching server takes the reference call quality value as the actual call quality value of the second transit service platform.

In the case that the vacancy rate of the second transit service platform is greater than the second threshold, the dispatch server may use the reference call quality calculated in step 40221 as the actual call quality value of the second transit service platform. For example, the second threshold is set to 30%, and if the obtained vacancy rate of the second transit service platform is 50%, and the reference call quality value is calculated to be 50 through the step 40221, the reference call quality value 50 is used as the actual call quality value of the second transit service platform.

40223 if the vacancy rate of the second transit service platform is less than the second threshold, the dispatch server takes the product of the reference call quality value and the vacancy rate of the second transit service platform as the actual call quality value of the second transit service platform.

And under the condition that the vacancy rate of the second transit service platform is smaller than a second threshold value, the dispatching server multiplies the reference call quality by the vacancy rate of the second transit service platform to obtain a product which is used as the actual call quality of the second transit service platform. For example, if the second threshold is set to 30%, and the obtained vacancy rate of the second transit service platform is 20%, and the reference call quality value is calculated to be 50 in the above step 40221, the actual call quality value of the second transit service platform is 20% × 50 ═ 10.

4023. And the scheduling server acquires the weighted value of the actual call quality value of each second transit service platform in the sum of the actual call quality values of all the second transit service platforms.

The dispatching server obtains the sum of the actual call quality values of all the second transit service platforms by adding the actual call quality values of all the second transit service platforms, and obtains the weighted value of the actual call quality value of each second transit service platform in the sum of the actual call quality values of all the second transit service platforms by dividing the actual call quality value of each second transit service platform by the sum of the actual call quality values of all the second transit service platforms.

For example, the dispatch server determines four second transit service platforms from the plurality of first transit service platforms according to the first performance parameters of the plurality of first transit service platforms, which are respectively a second transit service platform a, a second transit service platform B, a second transit service platform C, and a second transit service platform D, wherein the actual call quality value of the second transit service platform a is 20, the actual call value of the second transit service platform B is 25, the actual call quality value of the second transit service platform C is 25, the actual call quality value of the second transit service platform D is 30, and by adding the actual call quality value 20 of the second transit service platform a, the actual call quality value 25 of the second transit service platform B, the actual call quality value 25 of the second transit service platform C, and the actual call quality value 30 of the second transit service platform, obtaining the sum of the actual call quality values of all the second transit service platforms as 100, dividing the actual call quality value 20 of the second transit service platform A by the sum of the actual call quality values of all the second terminal service platforms as 100, and obtaining the weighted value of the second transit service platform A in the sum of the actual call quality values of all the second terminal service platforms as 0.2; dividing the actual call quality value 25 of the second transit service platform B by the sum 100 of the actual call quality values of all the second terminal service platforms to obtain the weighted value of 0.25 of the second transit service platform B in the sum of the actual call quality values of all the second terminal service platforms; dividing the actual call quality value 25 of the second transit service platform C by the sum 100 of the actual call quality values of all the second terminal service platforms to obtain the weighted value of 0.25 of the second transit service platform C in the sum of the actual call quality values of all the second terminal service platforms; dividing the actual call quality value 30 of the second transit service platform D by the sum 100 of the actual call quality values of all the second terminal service platforms to obtain a weighted value of 0.3 of the second transit service platform D in the sum of the actual call quality values of all the second terminal service platforms.

4024. And the dispatching server determines a target transit service platform from the plurality of second transit service platforms by adopting a specified algorithm according to the weight value corresponding to each second transit service platform.

In this embodiment, the designated algorithm may be a weighted random algorithm or the like. When a target transit service platform is determined from a plurality of second transit service platforms by adopting a weighted random algorithm, a weighted value corresponding to each second transit service platform is used as a probability of being selected by a scheduling server, if the weighted value corresponding to any second transit service platform is larger, the probability of being selected by the second transit service platform is correspondingly larger, and if the weighted value corresponding to any second transit service platform is smaller, the probability of being hit by the second transit service platform is correspondingly smaller.

For example, the weighted value corresponding to the second transit service platform a is 0.2, the weighted value corresponding to the second transit service platform B is 0.25, the weighted value corresponding to the second transit service platform C is 0.25, and the weighted value corresponding to the second transit service platform D is 0.3, when the scheduling server determines the target transit service platform in the four second transit service platforms, the probability that the second transit service platform a is selected is 0.2, the probability that the second transit service platform B is selected is 0.25, the probability that the second transit service platform C is selected is 0.25, and the probability that the second transit service platform D is selected is 0.3.

In this embodiment, the dispatch server optimizes the PSTN line quality of the plurality of first transit service platforms according to the first performance parameter, thereby ensuring that the transit service platform with the best quality can be selected for each call. Meanwhile, according to the real-time statistical result of the first performance parameter, the transfer service platform with poor quality is rapidly found, complaints and faults are eliminated, furthermore, the statistical result of the first performance parameter can be utilized to dynamically adjust the call volume of different transfer service platforms, and therefore different transfer service platforms are urged to actively carry out PSTN line optimization.

403. And the scheduling server acquires second performance parameters of a plurality of first Session Initiation Protocol (SIP) servers in the target transit service platform.

The second performance parameter includes a network connection rate, a connection success rate, a vacancy rate, and the like of the first SIP server. Since the scheduling server and the SIP server cluster in the target relay service platform can directly communicate, the scheduling server can obtain the latest statistical data of the network communication rate, the connection success rate, the vacancy rate, and the like of each first SIP server in the target relay service platform, and calculate the latest statistical data to obtain the second performance parameter of each first SIP server.

In order to distinguish the plurality of SIP servers on the target relay service platform, in this embodiment, all the SIP servers on the target relay service platform that are not screened are referred to as a first SIP server, the SIP server screened from the first SIP server is referred to as a second SIP service, and the SIP server screened from the second SIP server is referred to as a first target SIP server.

404. The dispatch server determines a first target SIP server from the plurality of first SIP servers based on the second performance parameters of the plurality of first SIP servers.

When the step is implemented specifically, the following steps 4041-4043 can be adopted:

4041. the dispatch server determines a plurality of second SIP servers from the plurality of first SIP servers based on the second performance parameters of the plurality of first SIP servers.

After the second performance parameters of the plurality of first SIP servers are acquired, the scheduling server compares the second performance parameters of each first SIP server with a third threshold value, and if the network communication rate, the connection success rate and the vacancy rate of any one first SIP server are all larger than the third threshold value, the first SIP server is used as a second SIP server; and if any one of the network connection rate, the connection success rate and the vacancy rate of any first SIP server is smaller than a third threshold value, excluding the first SIP server. The third threshold is set by the scheduling server according to the historical data, and may be 60%, 70%, 90%, and the like, and the size of the third threshold is not specifically limited in this embodiment.

4042. And the scheduling server acquires the weighted value of the vacancy rate of each second SIP server in the sum of the vacancy rates of all the second SIP servers.

And the scheduling server adds the vacancy rates of all the second SIP servers to obtain the sum of the vacancy rates of all the second SIP servers, and divides the vacancy rate of each second SIP server by the sum of the vacancy rates of all the second SIP servers to obtain the weighted value of the vacancy rate of each second SIP server in the sum of the vacancy rates of all the second SIP servers.

For example, the scheduling server determines four second SIP servers from the plurality of first SIP servers, namely a second SIP server a, a second SIP server B, a second SIP server C and a second SIP server D, according to the second performance parameter of the plurality of first SIP servers, wherein the vacancy rate of the second SIP server a is 30%, the vacancy rate of the second SIP server B is 20%, the vacancy rate of the second SIP server C is 25%, the vacancy rate of the second SIP server D is 25%, the sum of the vacancy rates of all the second SIP servers is 100% by adding the vacancy rate of the second SIP server a of 30%, the vacancy rate of the second SIP server B of 20%, the vacancy rate of the second SIP server C of 25% and the vacancy rate of the second SIP server D of 25%, the sum of the vacancy rates of all the second SIP servers is 100%, the vacancy rate of the second SIP server a of 30% is divided by the sum of the vacancy rates of all the second SIP servers of 100%, obtaining that the weight value of the vacancy rate of the second SIP server A in the sum of the vacancy rates of all the second SIP servers is 0.3, dividing 20% of the vacancy rate of the second SIP server B by 100% of the sum of the vacancy rates of all the second SIP servers, obtaining that the weight value of the vacancy rate of the second SIP server B in the sum of the vacancy rates of all the second SIP servers is 0.2, dividing 25% of the vacancy rate of the second SIP server C by 100% of the sum of the vacancy rates of all the second SIP servers, obtaining that the weight value of the vacancy rate of the second SIP server C in the sum of the vacancy rates of all the second SIP servers is 0.25, dividing 25% of the vacancy rate of the second SIP server D by 100% of the sum of the vacancy rates of all the second SIP servers, and obtaining that the weight value of the vacancy rate of the second SIP server D in the sum of the vacancy rates of all the second SIP servers is 0.25.

4043. And the scheduling server determines a first target SIP server from the plurality of second SIP servers by adopting a specified algorithm according to the weight value corresponding to each second SIP server.

In this embodiment, the designated algorithm may be a weighted random algorithm or the like. When a weighted random algorithm is adopted to determine a first target SIP server from a plurality of second SIP servers, a weighted value corresponding to each second SIP server is taken as the probability of being selected by a scheduling server, if the weighted value corresponding to any second SIP server is larger, the probability of being selected by the second SIP server is correspondingly larger, and if the weighted value corresponding to any second SIP server is smaller, the probability of being selected by the second SIP server is correspondingly smaller.

For example, if the weighted value corresponding to the second SIP server a is 0.3, the weighted value corresponding to the second SIP server B is 0.2, the weighted value corresponding to the second SIP server C is 0.25, and the weighted value corresponding to the second SIP server D is 0.25, then the scheduling server determines that the first target SIP server is the target of the four second SIP servers, the probability that the second SIP server a is selected is 0.3, the probability that the second SIP server B is selected is 0.2, the probability that the second SIP server C is selected is 0.25, and the probability that the second SIP server D is selected is 0.25.

In another embodiment of the present invention, after the scheduling server determines the first target SIP server, the location information of the first target SIP server is further obtained according to the IP address of the first target SIP server, and the location information of the first target SIP server includes the country, province, city, etc. where the first target SIP server is located.

405. The scheduling server obtains third performance parameters for a plurality of third SIP servers within the IP network.

The third performance parameter includes a network connection rate, a connection success rate, a vacancy rate, and the like of the third SIP server. Since the scheduling server and the SIP server cluster in the IP network can directly communicate, the scheduling service can obtain the latest statistical data of the network communication rate, the connection success rate, the vacancy rate, and the like of each third SIP server in the IP network, and calculate the latest statistical data to obtain the third performance parameter of each third SIP server.

In order to distinguish the plurality of SIP servers in the IP network, in the present embodiment, all the SIP servers in the IP network that are not screened are referred to as a third SIP server, the SIP server screened from the third SIP server is referred to as a fourth SIP server, and the SIP server screened from the fourth SIP server is referred to as a second destination SIP server.

406. And the scheduling server determines a second target SIP server from the plurality of third SIP servers according to the third performance parameters of the plurality of third SIP servers.

4061. and the dispatching server determines a plurality of fourth SIP servers from the plurality of third SIP servers according to the third performance parameters of the plurality of third SIP servers.

After the third performance parameters of a plurality of third SIP servers are obtained, the scheduling server compares the third performance parameters of each third SIP server with a fourth threshold value, and if the network communication rate, the connection success rate and the vacancy rate of any third SIP server are all larger than the fourth threshold value, the third SIP server is used as a fourth SIP server; and if any one of the network communication rate, the connection success rate and the vacancy rate of any third SIP server is less than a fourth threshold value, excluding the third SIP server. The fourth threshold is set by the scheduling server according to the historical data, and may be 60%, 70%, 90%, and so on, and the size of the fourth threshold is not specifically limited in this embodiment.

4062. And the dispatching server determines a plurality of fifth SIP servers from the plurality of fourth SIP servers according to the position information of the first target SIP server.

When the step is implemented specifically, the following steps 40621-40624 can be adopted:

40621. the scheduling server acquires location information of a plurality of fourth SIP servers.

And the scheduling server acquires the position information of each fourth SIP server according to the IP address of each fourth SIP server, wherein the position information comprises the country, province, city and the like of the fourth SIP server.

40622. For any fourth SIP server, the scheduling server judges whether the position information of the fourth SIP server is the same as the position information of the first target SIP server.

For any fourth SIP server, the scheduling server compares the location information of the fourth SIP server with the location information of the first target SIP server to judge whether the location information of the fourth SIP server is the same as the location information of the first target SIP server.

40623. And if the position information of the fourth SIP server is the same as the position information of the first target SIP server, the dispatching server takes the fourth server as a fifth SIP server.

If the location information of the fourth SIP server is the same as the location information of the first target SIP server, the first terminal and the second terminal are in the same location area, and at this time, the scheduling server preferentially selects the fourth SIP server as a fifth SIP server, so as to save transmission resources.

40624. And if the position information of the plurality of fourth SIP servers is different from the position information of the first target SIP server, the dispatching server takes the plurality of fourth SIP servers as a plurality of fifth SIP servers.

When the position information of the plurality of fourth SIP servers is different from the position information of the first target SIP server, the first terminal and the second terminal are in different position areas, and at the moment, the scheduling server reserves all the fourth SIP servers as fifth SIP servers and performs screening in the subsequent steps.

4063. And the scheduling server acquires the weight value of the vacancy rate of each fifth SIP server in the sum of the vacancy rates of all the fifth SIP servers.

And the scheduling server adds the vacancy rates of all the fifth SIP servers to obtain the sum of the vacancy rates of all the fifth SIP servers, and divides the vacancy rate of each fifth SIP server by the sum of the vacancy rates of all the fifth SIP servers to obtain the weighted value of the vacancy rate of each fifth SIP server in the sum of the vacancy rates of all the fifth SIP servers.

4065. And the scheduling server determines a second target SIP server from the plurality of fifth SIP servers by adopting a specified algorithm according to the weight value corresponding to each fifth SIP server.

In this embodiment, the designated algorithm may be a weighted random algorithm or the like. When a weighted random algorithm is adopted to determine a second target SIP server from a plurality of fifth SIP servers, a weighted value corresponding to each fifth SIP server is taken as the probability of being selected by a scheduling server, if the weighted value corresponding to any fifth SIP server is larger, the probability of being selected by the fifth SIP server is correspondingly larger, and if the weighted value corresponding to any fifth SIP server is smaller, the probability of being selected by the fifth SIP server is correspondingly smaller.

407. And the scheduling server acquires fourth performance parameters of a plurality of first media stream servers in the IP network.

The fourth performance parameter includes a network delay, a network packet loss rate, a vacancy rate, and the like of the first media stream server. Since the scheduling server can directly communicate with the media stream server cluster in the IP network, the scheduling server can obtain the latest statistical data of the network connection rate, connection success rate, vacancy rate, and the like of each first media stream server in the IP network, and calculate the fourth performance parameter of each first media stream server by using the latest statistical data.

In order to distinguish a plurality of media streaming servers in the IP network, in this embodiment, all media streaming servers in the IP network that are not screened are referred to as a first media streaming server, a media streaming server screened from the first media streaming server is referred to as a second media streaming server, and a media streaming server screened from the second media streaming server is referred to as a target media server.

4081. and the scheduling server determines a plurality of second media streaming servers from the plurality of first media streaming servers according to the fourth performance parameters of the plurality of first media streaming servers.

After the fourth performance parameters of the plurality of first media stream servers are obtained, the scheduling server compares the fourth performance parameters of each first media stream server with a fifth threshold, and if the network delay, the network packet loss rate and the vacancy rate of any first media stream server are greater than the fifth threshold, the first media stream server is used as a second media stream server; and if any one of the network delay, the network packet loss rate and the vacancy rate required by any one first media stream service is smaller than a fifth threshold value, excluding the first media stream server. The fifth threshold is set by the scheduling server according to the historical data, and may be 60%, 70%, 90%, and so on, and the size of the fifth threshold is not specifically limited in this embodiment.

4082. The scheduling server obtains the position information of a plurality of third media stream servers in the target transit service platform, and the position information of the plurality of third media stream servers is reported by the plurality of second media stream servers.

The location information of the third media stream server includes a country, a province, a city, an ISP, etc. where the third media stream server is located. Because the media stream server in the IP network can communicate with the media stream server on the target relay service platform, the multiple second media stream servers in the IP network can obtain the multiple third media stream servers on the target relay service platform, and report the obtained location information of the third media stream servers to the scheduling server.

4083. And the scheduling server determines a plurality of fourth media stream servers from the plurality of second media stream servers according to the position information of the second terminal and the position information of the plurality of third media stream servers.

And the scheduling server searches a plurality of second media stream servers which are the same as the position information of the second terminal and the position information of the third media stream servers from the plurality of second media stream servers according to the position information of the second terminal and the position information of the third media stream servers to serve as a fourth media stream server.

4084. And the scheduling server acquires the weighted value of the vacancy rate of each fourth media stream server in the sum of the vacancy rates of all the fourth media stream servers.

And the scheduling server adds the vacancy rates of all the four media stream servers to obtain the sum of the vacancy rates of all the fourth media stream servers, and divides the vacancy rate of each fourth media stream server by the sum of the vacancy rates of all the fourth media stream servers to obtain the weighted value of the vacancy rate of each fourth media stream server in the sum of the vacancy rates of all the fourth media stream servers.

4085. And the scheduling server determines a target media stream server from the plurality of fourth media stream servers by adopting a specified algorithm according to the weight value corresponding to each fourth media stream server.

In this embodiment, the designated algorithm may be a weighted random algorithm or the like. When a target media stream server is determined from a plurality of fourth media stream servers by adopting a weighted random algorithm, a weighted value corresponding to each fourth media stream server is taken as the probability of being selected by a scheduling server, if the weighted value corresponding to any fourth media stream server is larger, the probability of being selected by the fourth media stream server is correspondingly larger, and if the weighted value corresponding to any fourth media stream server is smaller, the probability of being selected by the fourth media stream server is correspondingly smaller.

409. And the scheduling server determines a transmission link between the first terminal and the second terminal according to the target transfer service platform, the first target SIP server, the second target SIP server and the target media stream server.
