Problems solved by technology

Due to the flat structure of the traditional Internet, the nodes can be directly connected, the data transmission efficiency is high, and the IP address of the user is fixed, so the current P2P technology has been well developed in the traditional Internet; while the mobile Internet is a centralized hierarchical structure , and the network resources are limited, the user's IP address will also change; based on the above differences, the existing technology cannot directly copy the P2P application mode of the traditional Internet on the mobile Internet

Embodiment 1

[0101]In this embodiment, there are three mobile terminals, UE01, UE02, and UE03 all access the IMS core network through EVDO, wherein UE01 is used as a calling terminal, and UE02 and UE03 are used as called terminals.

[0102] Step 1: UE01 sends an Invite message to the video sharing server, and the video sharing server forwards the Invite message to two called terminals UE02 and UE03, and the Invite message received by the called terminal includes the IP address of the video sharing server;

[0103] Step 2: The SDP of the response message (200ok) sent by UE02 to the video sharing server contains fields: "Term Type==MobilePhone, Access Type==EVDO, UplinkBandWidth==800"; where Term Type represents the terminal type, and Access Type represents Access mode, UplinkBandWidth means uplink bandwidth;

[0104] The SDP of the response message sent by UE03 to the video sharing server contains fields: "Term Type==MobilePhone, Access Type==EVDO, UplinkBandWidth==500";

[0105] Step 3: T...

Embodiment 2

[0110] On the basis of the first embodiment, a called terminal UE04 is added, which is a mobile terminal: TermType=MobilePhone, but accesses the IMS core network through GPRS.

[0111] The video sharing server first obtains the UE04's attribution from the HSS. If the UE04's attribution is different from that of UE02 and UE03, set the video data direction of UE04 to RecvFromServer, that is, the video sharing server directly sends video data to UE04;

[0112] If UE04 belongs to the same location as UE02 and UE03, and since UE02, UE03 and UE04 are all mobile terminals, then determine the wireless access mode of UE04. Since the wireless access mode of UE04 is GPRS, the wireless access mode of UE02 and UE03 If the method is EVDO, then according to the uplink bandwidth of UE02 and UE03, set the video data direction of UE02 with the largest uplink bandwidth to SendRecv, and set the video data directions of UE03 and UE04 to RecvFromTerm, then UE02 sends video data to UE03 and also send...

Embodiment 3

[0114] On the basis of the second embodiment, a called terminal UE05 is added, the type of the terminal is a mobile terminal, Term Type=MobilePhone, and the terminal accesses the IMS core network through the WLAN.

[0115] Similarly, the video sharing server first obtains UE05's home location from the HSS. If UE05's home location is different from that of UE02, UE03, and UE04, set the video data direction of UE05 to RecvFromServer, and UE05 directly receives video data from the video sharing server. UE02, UE03, and The video data direction of UE04 is carried out according to the second embodiment;

[0116] If UE05 belongs to the same place as UE02, UE03, and UE04, the video sharing server judges the terminal type of UE05 according to the Term Type, and learns that the terminal type of UE05 is a mobile terminal, which is the same as UE02, UE03, and UE04; then judges the wireless access type according to the Access Type. The wireless access method of UE05 is WLAN, the wireless a...

Abstract

The invention discloses a method and a system for realizing multi-party video share. A calling terminal initiates a video sharing request to a plurality of called terminals through a video sharing server, and the called terminal receiving the video sharing request returns response message to the video sharing server; the video sharing server determines the video data direction of the called terminal according to the home of the called terminal, a terminal type, an access mode and a priority sequence of uplink bandwidth; and the called terminal provides shared video data for other terminals according to the determined video data direction. According to the method and the system, a mobile terminal, an IPTV and a soft terminal can participate in video share by using P2P technology so as to enhance user experience and attract more users to use video sharing services; and in addition, the called terminal can receive the video data from other terminals and does not need to receive the video data from a video server so as to lower the operating cost and promote the efficiency of the video sharing server.

Description

technical field [0001] The invention relates to a multi-party video sharing technology of a mobile Internet, in particular to a method and system for realizing multi-party video sharing based on peer-to-peer (P2P, Peer-to-Peer) Internet technology. Background technique [0002] IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) is a subsystem supporting IP multimedia services proposed in the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) Release 5 standard; Session Initiation Protocol (SIP, Session Initiation Protocol ) is a text-based signaling protocol that works in the client / server mode. The IP Multimedia Subsystem (IMS, IPMultimedia Subsystem) core network uses the SIP call control mechanism to create, manage and terminate various types of multimedia services, such as: video Shared services: The salient features of video sharing services are: adoption of SIP protocol, separation of control functions and carrying capacity, separation of...
