FIG. 5 is a flow chart of a network conference method according to another embodiment of the present invention. As shown in FIG. 5, in this embodiment, the technical solution according to this embodiment is described in detail by using the case where a UE initiates a conference request for creating a conference as an example. The method according to this embodiment includes:
501: A UE sends an information acquisition request to a center server (Center)
The information acquisition request is used to request proxy server information from the center server.
In this embodiment, the UE sends the information acquisition request to the center server to create a conference.
502: After receiving the information acquisition request, the Center returns information of registered proxy servers (proxy) to the UE.
In this embodiment, the proxy server information includes information of the registered proxy servers. The proxy server information may be arranged by the Center according to registration information sent by each proxy, or may be deployed by the system and arranged and stored by using the information of each proxy server. The proxy server information specifically includes: address of the Proxy, and conference number of the conference being processed by the Proxy.
503: After receiving the proxy server information, the UE detects each Proxy in the proxy server information.
In this embodiment, the detection of each Proxy in the proxy server information by the UE specifically includes: sending the detection information to the registered proxy servers; and when information returned by the registered proxy servers according to the detection information is received, acquiring speeds of the proxy servers and a current status of each proxy server according to the information returned by the registered proxy servers.
The detection information is used to request the speeds (that is, available bandwidths) and current statuses of the proxy servers. It should be noted that the current statuses of the proxy servers, that is, busy degree of the proxy servers, may be measured by whether the proxy servers are occupied by conferences or whether conferences are queuing for the proxy servers.
504: The UE selects Proxy 1 complying with a second preset standard in the proxy server information according to the detected speeds of the proxy servers and the current status of each proxy server, uses Proxy 1 as a destination proxy server, and initiates a request for creating a conference to the destination proxy server Proxy 1.
In this embodiment, the second preset standard may be that the proxy servers whose current status is that they are occupied by the conferences or the number of conferences queuing for the proxy servers is smaller than a first preset threshold, and the speeds of the proxy servers are the highest among the servers smaller than the preset threshold. Selection of the proxy server may optimize a communication channel of the network conference, and enable the user equipment to select the proxy server according to the network condition. The first preset threshold may be set by the conference system according to the conference capacity, the number of conference members, or the processing speed of the proxy server.
Steps 501-504 describe the process of selecting a proxy server by the UE. During the process, the UE detects network conditions such as the bandwidth of each proxy server in the network according to the received proxy server information, and selects a destination proxy server according to the detection result.
505: Proxy 1 receives a conference request and determines whether the conference request carries a conference number.
If no conference number is carried, the conference request is a request for creating a conference, and step 506 is performed.
If a conference number is carried, the conference request is a request for joining a conference, and the information of the floor server where the conference corresponding to the conference number is located is requested from the center server.
In this embodiment, in step 505, the type of the conference request is determined. If the conference request carries a conference number, the conference request is a request for joining a conference; if the conference request carries no conference number, the conference request is a request for creating a conference. Therefore, the following steps are described based on the case where the conference request carries no conference number.
506: Request information of the floor servers registered in the Center from the center server Center.
In this embodiment, the conference request carries no conference number. Therefore, the information acquisition request from the proxy server to the Center carries no information of the conference number.
507: The Center returns the information of the floor servers registered in the Center to Proxy 1 according to the request.
In this embodiment, when receiving the request for returning the floor server information, the Center determines whether the request carries a conference number; if a conference number is carried, returns information of the server where the conference indicated by the conference number is located; otherwise, returns the information of the floor servers registered in the center server.
508: Proxy 1 detects the floor servers in the floor server information according to the received floor server information, and uses a floor server Floor 1 complying with a first present standard as a destination floor server.
In this embodiment, step 508 specifically includes: sending detection information to the floor servers in the floor server information; receiving information returned by the floor servers according to the detection information; and acquiring the speeds of the floor servers and the current statuses of the floor servers according to the information returned by the floor servers.
The detection information is used to request the speeds (that is, available bandwidths) and current statuses of the floor servers. It should be noted that the current statuses of the floor servers, that is, busy degree of the floor servers, may be measured by whether the floor servers are occupied by conferences or whether conferences are queuing for the floor servers.
In this embodiment, the first preset standard may be that the floor servers whose current status is that they are occupied by the conferences or the number of conferences queuing for the floor servers is smaller than a first preset threshold, and the speeds of the floor servers are the highest among the floor servers smaller than the preset threshold. That is, a floor server in the detected floor severs that complies with the first preset standard is used as a destination floor server. Selection of the floor server may optimize a communication channel of the network conference, and enable the proxy server to select the floor server according to the network condition. The first preset threshold may be set by the conference system according to the conference capacity, the number of conference members, or the processing speed of the floor server.
509: Send the request for creating the conference to the destination floor server Floor 1.
Those skilled in the art may acquire that the conference request in step 509 may be a request for establishing a media channel.
510: Proxy 1 establishes a media channel with Floor 1.
511: Proxy 1 establishes a media channel with the UE.
It should be noted that establishing a media channel between a proxy server and a floor server, and a media channel between a proxy server and the UE is common knowledge for those skilled in the art, which is not detailed here.
512: Proxy 1 sends registration information to the Center.
In this embodiment, the registration information includes the conference number of the destination floor server and a local address, and the registration information is sent to the Center by using the registration information so that the Center acquires the active proxy server and the active conference in the current system. It should be noted that the conference number is generated during the process of establishing the conference, which is not detailed in the present invention.
Before step 512, the method further includes: receiving a conference number from the destination floor server and forwarding the conference number to the user equipment.
The conference number from the destination floor server is assigned by the destination floor server.
513: The UE carries out a network conference with the center by using the established media channels.
The user equipment may detect the proxy servers according to the information provided by the center server and select a proxy server complying with a standard as a destination proxy server; or the proxy server may detect the floor servers according to the information provided by the center server and use a floor server complying with a standard as a destination floor server, which ensures that services used by users during a network conference are provided by the proxy server or floor server complying with the standard, and improves the quality of the network conference.
FIG. 6 is a flow chart of a network conference method according to another embodiment of the present invention. As shown in FIG. 6, in this embodiment, the technical solution according to this embodiment is described in detail by using the case where a UE initiates a conference request for joining a conference, the request for joining a conference carries a conference number of the conference to join, the conference corresponding to the conference number is Meeting 1, and the floor server where Meeting 1 is located is Floor 2 as an example. The method according to this embodiment includes:
601: A UE sends an information acquisition request to a center server (Center), where the information acquisition request carries a conference number meeting 1.
602: After receiving the information acquisition request, the Center determines that the information acquisition request carries a conference number. Information of a proxy server being used by a conference member in the meeting 1 corresponding to the conference number and information of registered proxy servers are returned to the user equipment.
Preferably, the proxy server that is processing the conference is marked active.
603: After receiving the proxy server information, the UE detects the proxy server being used by a conference member in the conference corresponding to the conference number of the conference to join; and determines whether the proxy server being used compiles with a third preset standard according to the detection result. If the proxy server being used compiles with the third preset standard, a proxy server being used is used as a destination proxy server and step 605 is directly performed; otherwise, step 604 is performed.
According to an embodiment of the present invention, the third preset standard is set according to the capacity and processing speed of the current proxy server. Preferably, the third preset standard may be that the speed of the proxy server is greater than a preset threshold, and the current status is that the number of members joining the conference on the proxy server is smaller than the preset threshold.
The third preset standard is specifically used to determine whether a proxy server being used is suitable for accessing a new user equipment. In this way, when the new user equipment joins the conference, the quality of the network conference can be ensured.
604: The UE detects each Proxy registered in the proxy server information and uses a proxy complying with a second preset standard as a destination proxy server according to the detection result.
Specifically, the UE sends the detection information to the registered proxy servers; when information returned by the registered proxy servers according to the detection information is received, acquires the speeds of the proxy servers and the current status of each proxy server according to the information returned by the registered proxy servers; and uses a proxy server complying with a second preset standard as a destination proxy server according to the speeds of the proxy servers and the current status of each proxy server.
605: The UE sends a conference request to the destination proxy server, where the conference request is a request for joining a conference and carries the conference number of the conference to join. Assume that the destination proxy server in this embodiment is proxy 1.
606: Proxy 1 sends an information acquisition request, where the information acquisition request carries the conference number of the conference to join.
607: The Center returns information of a floor server where the conference corresponding to the conference number of the conference to join is located.
In this embodiment, the information of the floor server where a conference indicated by the conference number is located includes the address of the floor server Floor 2.
608: After receiving the information returned by the Center, Proxy 1 sends a conference request to the floor server.
When the request for joining the conference carries the conference number of the conference to join and information of the floor server where the conference corresponding to the conference number of the conference to join is located, steps 606-608 may be replaced by the following step: Proxy 1 sends the conference request to the floor server where the conference corresponding to the conference number of the conference to join is located.
It should be noted that the conference request is sent by the UE to Proxy 1. This step may be understood that Proxy 1 forwards the request for joining the conference from the UE to the floor server where the conference corresponding to the conference number of the conference to join is located.
The principles of steps 609-612 and steps 510-513 are the same, which are not detailed here.
The user equipment has acquired the conference number of the conference to join. Therefore, before step 513, the floor server does not need to assign a conference number to the proxy server, and the proxy server does not need to forward the conference number to the user equipment either. If the selected access server is another access server, step 513 needs to be performed. That is, the floor server assigns the conference number contained in the request for joining the conference to the proxy server, and the proxy server forwards the conference number to the user equipment.
The user equipment may detect the proxy servers according to the information provided by the center server and select a proxy server complying with a standard as a destination proxy server; or the proxy server may detect the floor servers according to the information provided by the center server and use a floor server complying with a standard as a destination floor server, which ensures that services used by users during a network conference are provided by the proxy server or floor server complying with the standard, and improves the quality of the network conference.
