Detailed Description

The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

In the prior art, the storage space of the terminal is getting larger and more multimedia resources can be stored, however, the terminals are distributed in different regions throughout the country, and the media playing requests and the network conditions in different regions are different, so the interrupted media transmission speeds in different regions are also different. How to schedule the media playing requests of each region to realize effective utilization of the multimedia resources stored in the terminal and determine a proper target resource terminal for the playing terminal.

In order to solve the problems in the prior art, embodiments of the present invention provide a multimedia resource scheduling method, an apparatus, and a scheduling server, so as to determine a suitable target resource terminal for a play terminal.

First, a multimedia resource scheduling method according to an embodiment of the present invention is introduced, where the multimedia resource scheduling method according to the embodiment of the present invention may be applied to the scheduling server 110 in the hybrid content distribution network system shown in fig. 1 a; the hybrid content distribution network system may further include a plurality of resource terminals, for example, may include a first resource terminal 120, a second resource terminal 130, a third resource terminal 140, a fourth resource terminal 150, a fifth resource terminal 160, a sixth resource terminal 170, a seventh resource terminal 180, and an eighth resource terminal 190 shown in fig. 1 a.

The broadcast terminal according to the embodiment of the present invention may be any one of the resource terminals described above. For example, it may be the first resource terminal 120. It is understood that the eight resource terminals are only exemplary, the scheduling server 110 may be communicatively connected with more resource terminals, and the broadcasting terminal may be any one of the more resource terminals.

In still other examples, when any resource terminal communicatively connected to the scheduling server 110 is to play the multimedia resource to be played but the resource terminal does not store the multimedia resource to be played, the resource terminal may be a playing terminal, for example, when the first resource terminal 120 does not store the multimedia resource to be played but plays the multimedia resource, the first resource terminal 120 may be a playing terminal.

In some examples, first resource terminal 120, second resource terminal 130, third resource terminal 140, and fourth resource terminal 150 may be interconnected to form a decentralized peer-to-peer network, and fifth resource terminal 160, sixth resource terminal 170, seventh resource terminal 180, and eighth resource terminal 190 may be interconnected to form another decentralized peer-to-peer network.

When the first resource terminal 120 needs to play the multimedia to be played, a play request may be sent to the scheduling server 110, and after receiving the play request, the scheduling server 110 may obtain geographic position information of the first resource terminal 120, and then, in an autonomous domain to which the first resource terminal belongs, from a minimum geographic hierarchy, based on current resource condition information and terminal performance information of each resource terminal in an area of each geographic hierarchy, step by step in the area of each geographic hierarchy, in an order from at least a resource and excellent to inferior terminal performance, at least one target resource terminal storing the multimedia resource to be played is searched; finally, the terminal identification information of each target resource terminal is sent to the first resource terminal 120, so that the first resource terminal 120 downloads the multimedia resource to be played from each target resource terminal.

For example, assuming that the found target resource terminals are the fifth resource terminal 160, the seventh resource terminal 180 and the eighth resource terminal 190, the terminal identification information of the fifth resource terminal 160, the terminal identification information of the seventh resource terminal 180 and the terminal identification information of the eighth resource terminal 190 may be sent to the first resource terminal 120, so that the first resource terminal 120 downloads the multimedia resource to be played from the fifth resource terminal 160, the seventh resource terminal 180 and the eighth resource terminal 190. The multimedia resource to be played may be video, audio, etc., and may be, for example, a movie or a tv series, etc.

Next, a multimedia resource scheduling method according to an embodiment of the present invention is described in detail, as shown in fig. 2, which is a flowchart of a first implementation manner of a multimedia resource scheduling method according to an embodiment of the present invention, and the method may be applied to the scheduling server 110, and the method may include:

s210, a playing request sent by the playing terminal is obtained, wherein the playing request comprises identification information of the multimedia resource to be played.

In some examples, the playing terminal may be communicatively connected to the scheduling server, and when a multimedia resource to be played by the playing terminal is not stored in the playing terminal, a playing request carrying identification information of the multimedia resource to be played may be sent to the scheduling server, and when the scheduling server receives the playing request sent by the playing terminal, the scheduling server may obtain the identification information of the multimedia resource to be played from the playing request.

In some examples, the multimedia resource to be played may be a video to be played, an audio to be played, or the like.

S220, obtaining the geographical position information of the playing terminal.

And S230, starting from the minimum geographical hierarchy in the autonomous domain to which the playing terminal belongs, searching for at least one target resource terminal storing the multimedia resources to be played in the geographical hierarchy areas step by step according to the sequence of resource from few to few and terminal performance from good to bad in the geographical hierarchy areas based on the current resource condition information and terminal performance information of each resource terminal in the geographical hierarchy areas.

S240, the terminal identification information of each target resource terminal is sent to the playing terminal, so that the playing terminal downloads the multimedia resource to be played from each target resource terminal.

After the identification information of the multimedia resource to be played is acquired, in order to enable the playing terminal to download the multimedia resource to be played in a suitable target resource terminal, the scheduling server may acquire the geographical position information of the playing terminal.

In still other examples, the geographic location information includes: playing an autonomous domain to which the terminal belongs and a plurality of geographical hierarchy information which is divided from small to large; the autonomous domain to which the playing terminal belongs is a geographical area corresponding to the autonomous domain system number to which the IP of the playing terminal belongs;

in some examples, after different resource terminals are communicatively connected to the scheduling server, in order to enable the scheduling server to distinguish the different resource terminals, each resource terminal may notify the scheduling server of its own IP, and the scheduling server may store the IP of each resource terminal therein.

In still other examples, the IP of each resource terminal will typically have a corresponding autonomous domain. It is understood that the global internet is divided into a plurality of autonomous domains, and operators, organizations, even companies, etc. of each country can apply for autonomous domain numbers, each assigned with a corresponding IP.

For example, the Chinese telecom operator has autonomous domain numbers AS17672, AS17785 and the like, and the network segments corresponding to the autonomous domain numbers AS17672 are 123.183.192.0-123.183.192.18; the network segment corresponding to the autonomous domain number AS17785 is 123.101.0.0-123.101.19.

The operator of China Unicom has autonomous domain numbers AS4808, AS17621, etc. The network segments corresponding to the autonomous domain number AS4808 are 1.119.192.0-1.119.192.21, 1.119.200.0-1.119.200.22 and the like, and the network segments corresponding to the autonomous domain number AS17621 are 27.115.0.0-27.115.0.17, 27.115.118.0-27.115.118.23 and the like.

Therefore, the scheduling server can divide the resource terminals having the respective IPs into different autonomous domains according to the autonomous domain to which the respective IPs belong.

In still other examples, resource terminals of different IPs are located in different geographical locations.

Therefore, the scheduling server may divide each resource terminal into a hierarchy in advance based on the IP of each resource terminal in an autonomous domain, for example, and then in an autonomous domain, may divide into: a national geographic level, a provincial geographic level, an urban geographic level, and the like, wherein the national geographic level is higher than the provincial geographic level, and the provincial geographic level is higher than the urban geographic level.

Assume that the eight resource terminals mentioned above are resource terminals located at different positions, for example, the first resource terminal 120 and the second resource terminal 130 are located in a1 city of a province, the third resource terminal 140 and the fourth resource terminal 150 are located in a2 city of a province, the fifth resource terminal 160 and the sixth resource terminal 170 are located in B1 city of B province, and the seventh resource terminal 180 and the eighth resource terminal 190 are located in B2 city of B province. The scheduling server described above may divide the eight resource terminals shown in fig. 1a into the hierarchy shown in fig. 1 b.

In FIG. 1B, solid box 1100 may represent an autonomous domain, dashed box 1110 may represent a provincial geographic hierarchy of province A, dashed box 1120 may represent a provincial geographic hierarchy of province B, dashed box 1111 may represent a municipality geographic hierarchy of city A1, dashed box 1112 may represent a municipality geographic hierarchy of city A2, dashed box 1121 may represent a municipality geographic hierarchy of city B1, and dashed box 1122 may represent a municipality geographic hierarchy of city B2.

By dividing each resource terminal according to the autonomous domain and the geographical hierarchy, the scheduling server can determine the autonomous domain to which the playing terminal belongs and a plurality of geographical hierarchy information divided from small to large after acquiring the playing request sent by the playing terminal. For example, assuming that the cast terminal is the first resource terminal 120, it can be determined that the geographic hierarchy information of the cast terminal from small to large is a1 city of province a and province a. Therefore, the geographical position information of the playing terminal can be acquired.

After acquiring the geographical position information of the play terminal, the scheduling server may search, in the autonomous domain to which the play terminal belongs, from the smallest geographical hierarchy, at least one target resource terminal storing the multimedia resource to be played in an order of resource from a minimum number and terminal performance from good to bad in each geographical hierarchy region step by step based on current resource condition information and terminal performance information of each resource terminal in each geographical hierarchy region.

In some examples, the current resource condition information and the terminal performance information of each resource terminal are reported to the scheduling server by each resource terminal in real time.

For example, after the eight resource terminals report their current resource status information and terminal performance information to the scheduling server in real time, the scheduling server may search for resources in the region of the local geographical hierarchy in a1 city in a province, in the order from a few resources and a good terminal performance to a bad terminal performance; then, the search is performed in the provincial geographical level region of provincial A provincial, in the order of resource change from high to low and terminal performance change from high to low, and the search is performed in the national geographical level region in the order of resource change from low to high and terminal performance change from low to high, for example, the search may be performed in the provincial geographical level of provincial B provincial.

When at least one target resource terminal storing the multimedia resource to be played is found, the scheduling server may send the terminal identification information of each target resource terminal to the playing terminal, and after the playing terminal receives the identification information of the at least one target resource terminal sent by the scheduling server, the playing terminal may send a download request to the second terminal based on the identification information of the at least one target resource terminal, so as to download the multimedia resource to be played from the at least one target resource terminal.

In some examples, the foregoing playing terminal may segment the multimedia resource to be played, and then send a download request carrying identification information of different multimedia resource segments to different target resource terminals, so that when a target resource terminal sends a corresponding multimedia resource segment to the playing terminal based on the received identification information of the multimedia resource segment. After the playing terminal downloads the multimedia resource fragments from different target resource terminals, the playing terminal can combine the received multimedia resource fragments into a complete multimedia resource to be played and then play the multimedia resource based on the identification information of each multimedia resource fragment.

The multimedia resource scheduling method provided by the embodiment of the invention can firstly acquire the playing request sent by the playing terminal and the geographical position information of the playing terminal; then, in an autonomous domain to which the playing terminal belongs, starting from the minimum geographical hierarchy, searching for at least one target resource terminal storing multimedia resources to be played in the order of resource from few to few and terminal performance from good to bad in each geographical hierarchy region step by step based on current resource condition information and terminal performance information of each resource terminal in each geographical hierarchy region; and finally, sending the terminal identification information of each target resource terminal to the playing terminal so that the playing terminal downloads the multimedia resource to be played from each target resource terminal.

The geographical location information includes: playing an autonomous domain to which the terminal belongs and a plurality of geographical hierarchy information which is divided from small to large; the current resource condition information and terminal performance information of each resource terminal are reported to the scheduling server by each resource terminal in real time; therefore, at least one target resource terminal storing the multimedia resources to be played can be searched in the region of each geographic level step by step according to the sequence of resource from few to few and terminal performance from good to bad in the region of each geographic level based on the current resource situation information and terminal performance information of each resource terminal in the region of each geographic level. Moreover, when searching for the target resource terminal, the target terminal with more resources and better terminal performance is searched preferentially, so that the proper target resource terminal can be determined for the playing terminal, and the playing terminal can acquire the multimedia resource to be played from the target resource terminal based on the identification information of the target resource terminal.

On the basis of the multimedia resource scheduling method shown in fig. 2, an embodiment of the present invention further provides a possible implementation manner, as shown in fig. 3, which is a flowchart of a second implementation manner of the multimedia resource scheduling method of the embodiment of the present invention, in fig. 3, in step S230 shown in fig. 2, starting from a minimum geographic hierarchy in an autonomous domain to which a playing terminal belongs, based on current resource condition information and terminal performance information of each resource terminal in an area of each geographic hierarchy, in an area of each geographic hierarchy step by step, at least one target resource terminal storing multimedia resources to be played is searched according to an order from a minimum number of resources and a superior to a poor terminal performance, where the method may include:

s2301, in an autonomous domain where the playing terminal belongs, starting from the smallest geographical hierarchy, obtaining priority classes of each resource terminal in each geographical hierarchy region, and searching for at least one target resource terminal storing multimedia resources to be played in each geographical hierarchy region step by step according to the sequence of the priorities from high to low; the priority classes of the resource terminals in each geographic hierarchy region are divided according to the current resource situation information and terminal performance information of the resource terminals in the geographic hierarchy region.

In some examples, in order to facilitate the preferential selection of the target resource terminal with excellent performance and good resource condition, the scheduling server may divide, for each geographic hierarchy, the resource terminals in the region of the geographic hierarchy into different priority classes according to the current resource condition information and terminal performance information sent by the resource terminals in the region of the geographic hierarchy, so that the scheduling server may preferentially search for a higher priority class and then search for a lower priority class.

In still other examples, the resource status information may include identification information of the multimedia resource and integrity information of the multimedia resource; the terminal performance information may include terminal state information and terminal bandwidth occupation information; the scheduling server may classify, for each geographic hierarchy, each resource terminal in the region of the geographic hierarchy into different priority classes according to the identification information of the multimedia resource, the integrity information of the multimedia resource, the terminal state information, and the terminal bandwidth occupation information of each resource terminal in the region of the geographic hierarchy. Thus, each resource terminal corresponds to the identification information of at least one multimedia resource, the integrity information of at least one multimedia resource, the state information of at least one terminal and the bandwidth occupation information of at least one terminal.

Through the embodiment of the invention, the scheduling server can directly select from different priority classes, so that the time overhead during searching can be reduced, and the overall time for the playing terminal to play the multimedia resources to be played can be shortened.

In some examples, the integrity information of the multimedia asset includes: the terminal state information comprises the following information: an idle state and/or a busy state.

In some examples, when the scheduling server classifies priority classes for each resource terminal in the region of each geographic hierarchy, the scheduling server may classify the resource terminal corresponding to the complete multimedia resource information and the bandwidth occupation information whose terminal state is an idle state and is greater than a preset bandwidth threshold into a highest priority class; dividing resource terminals corresponding to multimedia resource fragment information and bandwidth occupation information of which the terminal state is an idle state and is less than a preset bandwidth threshold into a sub-priority class; and dividing the resource terminals which are not in the highest priority class and are not in the second priority class into the lowest priority class. In this way, each resource terminal in the region of each geographic hierarchy may be divided into three priority classes, and then the scheduling server may search from the highest priority class first, then search from the next priority class, and finally search from the lowest priority class.

It is to be understood that this is merely an exemplary illustration, and in practical applications, for each resource terminal in the area of each geographic hierarchy, the resource terminals may be divided into more or less priority classes, which may be all the same, for example, two priority classes, or four or five priority classes.

On the basis of the multimedia resource scheduling method shown in fig. 3, an embodiment of the present invention further provides a possible implementation manner, as shown in fig. 4, which is a flowchart of a third implementation manner of the multimedia resource scheduling method shown in the embodiment of the present invention, and in fig. 4, before acquiring a play request sent by a play terminal in step S210 shown in fig. 3, the method may include:

s250, aiming at resource terminals which store the same identification information of multimedia resources, dividing resource terminals corresponding to complete multimedia resource information and bandwidth occupation information of which the terminal state is an idle state and is greater than a preset bandwidth threshold value into the highest priority class corresponding to the multimedia resources;

s260, aiming at resource terminals which store the same identification information of multimedia resources, dividing resource terminals corresponding to multimedia resource fragment information and bandwidth occupation information of which the terminal state is an idle state and is less than a preset bandwidth threshold into sub-optimal priority classes corresponding to the multimedia resources;

s270, aiming at the resource terminals which store the same identification information of the multimedia resources, dividing the resource terminals which are not in the highest priority class and are not in the second best priority class into the lowest priority class corresponding to the multimedia resources;

in order to further facilitate the foregoing scheduling server to search for the target resource terminal, the foregoing scheduling server may perform priority class division on the resource terminals storing the same multimedia resource. For example, for resource terminals storing the same multimedia resource, the resource terminals corresponding to the complete multimedia resource information and the bandwidth occupation information whose terminal state is an idle state and is greater than the preset bandwidth threshold may be divided into the highest priority class corresponding to the multimedia resource; dividing resource terminals corresponding to multimedia resource fragment information and bandwidth occupation information of which the terminal state is an idle state and is less than a preset bandwidth threshold into sub-optimal priority classes corresponding to the multimedia resources; and dividing the resource terminals of the non-highest priority class and the non-second-priority class into the lowest priority class corresponding to the multimedia resource.

In some examples, the resource terminals are divided into resource terminals corresponding to the identification information of the respective multimedia resources based on the identification information of the multimedia resources stored in the resource terminals. Thus, the identification information of each multimedia resource can be made to correspond to at least one resource terminal.

It is understood that the steps S250, S260 and S270 may be executed simultaneously or not, and are not limited herein.

In some examples, in fig. 4, step S2301 shown in fig. 3, in an autonomous domain to which the playback terminal belongs, starting from a minimum geographic hierarchy, obtaining priority classes of resource terminals in areas of the geographic hierarchies, and searching for at least one target resource terminal storing a multimedia resource to be played in the areas of the geographic hierarchies in order from high priority to low priority, may include:

s23011, in an autonomous domain to which the playing terminal belongs, starting from a minimum geographical hierarchy, obtaining a priority class of each terminal of pending resources in an area of each geographical hierarchy, and gradually searching for at least one target resource terminal storing multimedia resources to be played in the area of each geographical hierarchy according to a sequence of priorities from high to low, where each terminal of pending resources is: and the resource terminal stores the multimedia resources which are the same as the identification information of the multimedia resources to be played.

After the scheduling server performs priority classification on the resource terminals storing the same multimedia resources, the scheduling server may perform step S23011 after step S220 is performed and the geographical location information of the playing terminal is acquired.

Since the scheduling server has already divided the priority classes of the resource terminals, when querying, at least one target resource terminal storing the multimedia resource to be played can be searched in the priority class of the resource terminal storing the multimedia resource identical to the identification information of the multimedia resource to be played in the region of the minimum geographic hierarchy in the order from high priority to low priority. And then, searching at least one target resource terminal storing the multimedia resources to be played in the region of the geographical hierarchy other than the minimum geographical hierarchy level by level according to the sequence from high priority to low priority.

By dividing the priority classes of the resource terminals storing the same multimedia resources in advance, the scheduling server can search only the priority classes of a plurality of resource terminals storing the same multimedia resources as the multimedia resources to be played when inquiring, and does not need to search the priority classes of the resource terminals storing the multimedia resources different from the multimedia resources to be played, so that the time overhead in the searching process can be further reduced.

On the basis of the multimedia resource scheduling method shown in fig. 3, an embodiment of the present invention further provides a possible implementation manner, as shown in fig. 5, which is a flowchart of a fourth implementation manner of the multimedia resource scheduling method of the embodiment of the present invention, in fig. 5, in step S2301 shown in fig. 3, in an autonomous domain to which a play terminal belongs, the priority class of each resource terminal in an area of each geographic hierarchy is obtained from a smallest geographic hierarchy, and at least one target resource terminal storing a multimedia resource to be played is searched for in the area of each geographic hierarchy step by step in an order from high priority to low priority, which may include:

s23012, taking the minimum geographical hierarchy as the current geographical hierarchy, and acquiring the priority classes of the resource terminals in the region of the current geographical hierarchy;

s23013, according to the priority from high to low, in the current geographic level area, searching at least one target resource terminal storing the multimedia resource to be played;

s23014, judging whether the number of the searched target resource terminals reaches a preset target resource terminal number threshold value; if the preset target resource terminal quantity threshold value is not reached, executing step S23015, and if the preset target resource terminal quantity threshold value is reached, executing step S240;

s23015, using the upper-level geographical hierarchy as the current geographical hierarchy, acquiring the priority class of each resource terminal in the area of the current geographical hierarchy, and executing S23013.

In some examples, when the scheduling server searches for a target resource terminal in an autonomous domain in which the play terminal is located, a certain number of target resource terminals may be searched for the play terminal, for this, the scheduling server may first search for at least one target resource terminal storing a multimedia resource to be played in an area of a minimum geographic hierarchy in an order from high priority to low priority in the minimum geographic hierarchy, and then may determine whether the number of the searched at least one target resource terminal meets a number requirement, and if so, may execute step S240.

If not, the search may be performed in an area of a previous geographic level of the minimum geographic level, and then it is determined whether the sum of the number of the at least one target resource terminal searched in the minimum geographic level and the number of the at least one target resource terminal searched in the previous geographic level meets the number requirement, and if yes, step S240 may be performed.

If not, a search may be made in the area of the upper two geographic levels of the minimum geographic level.

In some examples, when at least one target resource terminal storing the multimedia resource to be played is searched in the region of the current geographic hierarchy in order of priority from high to low, the at least one target resource terminal storing the multimedia resource to be played may be searched first from the highest priority category in the region of the current geographic hierarchy; then judging whether the number of the searched target resource terminals reaches a preset target resource terminal number threshold value, if not, searching at least one target resource terminal storing the multimedia resource to be played from the next-level priority class in the current geographical hierarchy region;

and judging whether the number of the searched target resource terminals reaches the preset target resource terminal number threshold value or not, if not, continuing to search at least one target resource terminal storing the multimedia resource to be played from the lower two-level priority class in the current geographic hierarchy region.

For example, assuming that the cast terminal is the first resource terminal 120, it can be determined that the geographic hierarchy information of the cast terminal from small to large is a1 city of province a and province a.

The scheduling server may first use the civic-level geographical hierarchy in city a1 as the current geographical hierarchy, and then obtain the priority categories of each resource terminal in the region of the civic-level geographical hierarchy in city a 1; and in the order of priority from high to low, in the region of the urban geographical hierarchy of a1, at least one target resource terminal holding the multimedia resource to be played is searched.

When the number of the target resource terminals found in the region of the city-level geographic hierarchy in a1 city is judged to be less than the preset target resource terminal number threshold, the province-level geographic hierarchy in a province is taken as the current geographic hierarchy, then the priority classes of the resource terminals in the region of the province-level geographic hierarchy in the province-level of the province are obtained, and then at least one target resource terminal storing the multimedia resource to be played is found in the region of the province-level geographic hierarchy in the province-level of the province from high to low according to the priority.

When the number of the target resource terminals found in the provincial level geographical level region of the provincial level of the.

In some examples, when at least one target resource terminal storing a multimedia resource to be played is searched in a region of a national geographic level, a provincial geographic level different from the provincial geographic level of province a may be selected for searching in the region of the national geographic level, for example, a provincial geographic level of province B may be searched. It is also possible to perform a search in a small area in the area of the national geographical level by performing a search in a provincial geographical level different from that of provincial geographical level of province a.

Therefore, the number of the target resource terminals returned to the playing terminal can meet the number requirement of the playing terminal, so that the playing terminal can download the multimedia resources to be played from the target resource terminals at the same time, and the time overhead of downloading the multimedia resources to be played by the playing terminal can be reduced.

On the basis of the multimedia resource scheduling method shown in fig. 5, an embodiment of the present invention further provides a possible implementation manner, as shown in fig. 6, which is a flowchart of a fifth implementation manner of the multimedia resource scheduling method shown in the embodiment of the present invention, in fig. 6, step S23015 shown in fig. 5, which takes a previous geographical hierarchy as a current geographical hierarchy, and obtains priority classes of each resource terminal in an area of the current geographical hierarchy, where the obtaining may include:

s230151, shifting the geographic position of the playing terminal based on the preset geographic position shift amount to obtain the shifted geographic position;

s230152, determining the minimum geographical level to which the shifted geographical position belongs;

s230153, using the upper geographical level of the minimum geographical level to which the shifted geographical location belongs as the current geographical level, obtaining the priority class of each resource terminal in the current geographical level region, and executing step S23013.

In some examples, after the scheduling server determines that the number of target resource terminals that have been found does not reach the preset threshold value of the number of target resource terminals, in order to avoid performing a search in an area of a previous geographical level, where a resource terminal in the area of the previous geographical level is determined to be a target resource terminal of multiple play terminals at the same time, a geographical position where the play terminal is located may be shifted, and then, starting from the area of the previous geographical level of the minimum geographical level to which the shifted geographical position belongs, the target resource terminals that store multimedia resources to be played are searched in order from high priority to low priority.

It can be understood that, when there are multiple playing terminals, the geographic positions of the playing terminals are usually different, so that after the geographic positions of the playing terminals are shifted, the shifted geographic positions are also different, the corresponding minimum geographic levels are also different, and the upper geographic levels corresponding to the lower geographic levels are also not completely the same, so that when a target resource terminal is searched for each playing terminal, the areas of the searched upper geographic levels are not completely the same, thereby avoiding that the same resource terminal is determined as a target resource terminal of multiple playing terminals, avoiding that the same resource terminal is overused, and further avoiding that the download speed of the multimedia resource to be played is too slow when the resource of the resource terminal is overused.

On the basis of the multimedia resource scheduling method shown in fig. 5, a possible implementation manner is further provided in the embodiments of the present invention, as shown in fig. 7, which is a flowchart of a sixth implementation manner of the multimedia resource scheduling method in the embodiments of the present invention, in step S23013 shown in fig. 5, after at least one target resource terminal storing a multimedia resource to be played is searched for in an area of a current geographic hierarchy in an order from high priority to low priority, when the number of target resource terminals that have been searched in an autonomous domain to which a playing terminal belongs does not reach a preset target resource terminal number threshold, the method may include:

s290, starting from the minimum geographical hierarchy in the target autonomous domain, searching at least one target resource terminal storing multimedia resources to be played in the geographical hierarchy areas step by step according to the sequence of resource from few to few and terminal performance from good to bad in the geographical hierarchy areas based on the current resource condition information and terminal performance information of each resource terminal in the geographical hierarchy areas; the target autonomous domain and the autonomous domain to which the playing terminal belongs belong to a plurality of autonomous domains which are divided in advance;

s2910, judging whether the number of the searched target resource terminals reaches a preset target resource terminal number threshold value; if the preset target resource terminal quantity threshold value is not reached, executing the step S2920; if the preset target resource terminal number threshold is reached, step S240 is executed.

S2920, in the autonomous domain not found, the target autonomous domain is reselected, and step S290 is executed.

In some examples, the number of resource terminals in the autonomous domain in which the playback terminal is located may be larger or smaller, and when the number of target resource terminals that have been found by the scheduling server in the autonomous domain in which the playback terminal is located does not reach the preset threshold value for the number of target resource terminals, the scheduling server may also search in other autonomous domains except the autonomous domain in which the playback terminal is located.

In some examples, there may be a plurality of autonomous domains other than the autonomous domain in which the playback terminal is located, and for this, the scheduling server may first select a target autonomous domain in an autonomous domain other than the autonomous domain to which the playback terminal belongs.

And then, in the target autonomous domain, starting from the minimum geographical hierarchy, searching for at least one target resource terminal storing multimedia resources to be played in the order of resource from few to few and terminal performance from good to bad in each geographical hierarchy region step by step based on the current resource condition information and terminal performance information of each resource terminal in each geographical hierarchy region.

Then, whether the number of the searched target resource terminals reaches a preset target resource terminal number threshold value can be judged; if the preset threshold of the number of target resource terminals has not been reached, a different target autonomous domain may be reselected, and step S290 is continuously performed to continuously search for target resource terminals. And until the number of the searched target terminals reaches a preset target resource terminal number threshold value. And finally, sending all the found identification information of the target resource terminal to the playing terminal.

It is understood that the target autonomous domain and the autonomous domain to which the cast terminal belongs belong to a plurality of autonomous domains divided in advance. The plurality of autonomous domains may be autonomous domains divided in the prior art.

By the embodiment of the invention, the searching in different autonomous domains can be realized, so that the target resource terminals meeting the quantity requirement can be searched for the playing terminals.
