Example 1
In accordance with an embodiment of the present invention, there is provided a method embodiment of gateway multiplexing, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than here.
Fig. 1 is a schematic flowchart of a gateway multiplexing method according to an embodiment of the present invention, and as shown in fig. 1, the method includes the following steps:
step S102, receiving a connection request sent by at least one receiving end;
step S104, judging whether the target objects of the connection requests sent by each receiving end are the same;
and step S106, forwarding the multimedia data stream of the target object to at least one receiving end under the condition that the judgment result is yes.
Specifically, in combination with steps S102 to S106, at the gateway device side, in the gateway device multiplexing method provided by the present application, the gateway device receives a connection request sent by at least one receiving end, and by determining whether a target object in the connection request of each receiving end is the same, if the determination result is yes, the gateway device directly feeds back acknowledgement response information to the receiving ends to indicate that each receiving end has connected to the target object, and at this time, the multimedia data stream sent by the target object is respectively sent to each receiving end.
For example, in a teaching scenario, the receiving end may be at least one PC computer, the target object may be a server storing a multimedia file with a communication function, and assuming that there are 10 computers, which are respectively denoted as computer 1, computer 2, computer 3, … …, and computer 10, the gateway device and the 10 computers are located in the same lan, when all the 10 computers need to access the server a, the gateway device uniformly returns a confirmation response message to each computer to indicate that each computer is connected to the server a, at this time, when the server a sends the multimedia file, it is not necessary to send the 10 computers one by one, the server a only needs to send one multimedia file, the gateway device sends the multimedia file to the 10 computers, thereby implementing the multiplexing function of the gateway device, saving signaling resources of the server a and link resources of the entire communication link, the pressure on the transmission bandwidth is reduced.
It should be noted that the foregoing examples of the present application are only used for illustrating the method for multiplexing the gateway provided by the present application, and the method for multiplexing the gateway provided by the present application is not limited specifically.
The gateway multiplexing method provided by the application provides multiplexing gateway equipment of real-time unidirectional media, and the access requests of a plurality of receiving terminals to the same media source in a service domain (generally in a Local Area Network (LAN) for short) are single access requests, so that the aim of multiplexing media channels is fulfilled. Further, signaling resources of media sources sequentially feeding back responses are saved, and the problem of bandwidth waste is avoided, specifically as shown in fig. 2, fig. 2 is a schematic diagram of a network structure in a gateway multiplexing method according to an embodiment of the present invention.
As shown in fig. 2, there are a source end and a plurality of sink ends in the wan. The receiving end and the gateway are in the same local area network. The source sends real-time unidirectional media. The gateway establishes a connection with a remote end via a protocol (e.g., the SIP protocol), receives media, and distributes the media to a plurality of receivers within the local area network.
In addition, if the determination result is negative, the connection request sent by the receiving end is forwarded to the corresponding target object.
In the embodiment of the invention, the connection request sent by at least one receiving end is received; judging whether the target objects of the connection requests sent by each receiving end are the same or not; and if the judgment result is yes, forwarding the multimedia data stream of the target object to at least one receiving end, so as to achieve the purpose of performing function multiplexing by the gateway equipment through real-time unidirectional multimedia transmission, thereby achieving the technical effect of saving the outlet bandwidth of the data source end, and further solving the technical problem of bandwidth waste in the process of real-time multimedia content transmission in the prior art.
Optionally, the step S102 of receiving the connection request sent by the at least one receiving end includes:
step1, judging whether the receiving end sending the connection request is the first terminal initiating the connection to the target object;
step2, if the judgment result is yes, establishing connection with the target object according to the connection response fed back by the target object;
and Step3, returning a connection response to the at least one receiving end if the judgment result is negative, wherein the connection response is used for indicating that the connection established between the at least one receiving end and the target object is successful.
Specifically, it should be noted that, in the process of connecting the receiving end with the target object, when the receiving end is the first terminal that sends the connection request to the target object, after receiving the connection request, the gateway device determines that the connection with the target object does not exist currently, and therefore, initiates the connection request to the target object. After the target object agrees with the connection request, the connection between the gateway device and the target object is successfully established. And the gateway equipment agrees with the connection request of the receiving end, and the connection between the receiving end and the gateway equipment is successfully established.
It should be noted that, after the first receiving end establishes a connection with the target object, the gateway device may reserve the communication link between the gateway device and the target object this time, and after the receiving end that also needs to be connected to the target object subsequently sends the connection request, the gateway device directly returns a connection response to the receiving end that subsequently sends the connection request.
Further, optionally, the forwarding the multimedia data stream of the target object to at least one receiving end in step S106 includes:
step1, receiving the multimedia data stream sent by the target object;
step2, forwarding the multimedia data stream to at least one receiving end.
Specifically, based on the foregoing, in the process of forwarding the multimedia data stream by the gateway device, the multimedia data stream file may be forwarded to each receiving end connected to the target object by receiving one multimedia data stream file sent by the target object.
Optionally, the gateway multiplexing method provided by the present application further includes:
step S107, receiving a connection release request sent by at least one receiving end;
step S108, judging whether the receiving end sending the connection release request is the last terminal;
step S109, releasing the connection between the receiving end and the target object under the condition that the judgment result is negative;
step S110, if the determination result is yes, releasing the connection between the receiving end and the target object, and sending a multimedia data stream stop sending request to the target object, so that the target object stops sending the multimedia data stream according to the multimedia data stream stop sending request.
Specifically, with reference to steps S107 to S110, the gateway multiplexing method provided in the present application specifically includes the following steps in the process of releasing link resources:
s1, when there is a receiving end not wanting to connect the target object, the receiving end initiates a connection releasing request to the gateway device;
s2, if the gateway device finds that other receiving terminals besides the receiving terminal multiplex the connection of the same target object, the gateway device directly agrees to the request, and does not forward the media stream sent by the target object to the receiving terminal any more;
s3, if the other receiving terminals do not want to connect to the target object, the other receiving terminals respectively initiate a connection release request (i.e., a connection release request provided by the present application) to the gateway device;
s4, if the gateway device finds that there is no connection between the receiving end and the target object besides these other receiving ends, the gateway device directly approves the connection releasing request and simultaneously initiates a connection releasing request to the target object.
And S5, the target object agrees to the connection release request and does not send the multimedia data stream to the gateway equipment any more.
Therefore, the access requests of a plurality of receiving terminals in the service domain to the same media source in the network are single access requests through the multiplexing gateway equipment of the real-time unidirectional media, and the purpose of multiplexing the media channels is achieved.
In summary, with reference to steps S102 to S110, fig. 3 is a schematic interaction diagram between a receiving end, a gateway device, and a target object in a gateway multiplexing method according to an embodiment of the present invention, and as shown in fig. 3, the gateway multiplexing method provided in the present application specifically includes:

s1, the R1 initiates a connection request to a gateway to connect a source end S;
s2, the gateway receives the request, finds that the connection with the S does not exist at present, and therefore initiates a connection request to the S;
s3.S agrees to the request, and the connection between the gateway and the S is successfully established;
and S4, the gateway agrees with the connection request of the R1, and the connection between the R1 and the gateway is successfully established. The gateway forwards the media stream sent by the S to R1;
s5, the R2 initiates a connection request to the gateway to connect the source end S;
s6. the gateway finds that a connection already exists with S and therefore grants the request of R2 directly. Meanwhile, the gateway forwards the media stream sent by the S to R1 and R2;
s7, R1 does not want to connect S, so a connection releasing request is sent to the gateway;
s8, the gateway finds that other receiving ends multiplex connection with the S besides R1, so that the request is directly agreed, and the media stream sent by the S is not forwarded to R1;
s9.R2 does not want to connect S, therefore, initiates a connection release request to the gateway;
s10, the gateway finds that the connection is the last connection with the S, so the gateway directly agrees to the request and simultaneously initiates a connection release request to the S;
s11.s agrees to the request and no more media is sent to the gateway.
The gateway multiplexing method provided by the application introduces a multiplexing gateway of real-time unidirectional media. The gateway makes access requests of a plurality of receiving terminals to the same media source in a service domain (generally in a Local Area Network (LAN) for short) into a single access request, thereby achieving the purpose of multiplexing media channels. Therefore, the exit bandwidth is saved, the user experience is optimized, and no special requirement is required on network equipment only through an application layer protocol. And has no special requirements for the media service provider.
