Abstract

The present invention discloses a method and an apparatus for establishing a session, and the method comprises: receiving a session request message from a calling terminal, wherein the session request message is used to request the establishment of a P2P session media connection between the calling terminal and a called terminal; according to the session request message, obtaining relay resource of a relay node; establishing the P2P session media connections among the calling terminal, the relay node and the called terminal by using the relay resource. According to the method and the device of the present invention, the P2P session between the calling terminal and the called terminal can be achieved, preventing cross-domain call, ensuring that the terminal delay and improving the user experience.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for establishing a session. Background technique [0002] At present, Peer-to-Peer (P2P for short) has fully demonstrated its strong technical advantages in file exchange, distributed computing, service sharing, etc. Applied in traditional telecommunication networks. [0003] In related technologies, many institutions are working on how to introduce P2P technology into the telecommunication network, which can not only ensure the application of the Session Initiation Protocol (SIP) in the P2P network, but also run various typical business. [0004] figure 1 is a schematic diagram of a P2P core network architecture according to related technologies, such as figure 1 As shown, it includes a P2P overlay network 101, a peer node 102 in the P2P overlay network, a non-P2P terminal device 103, a P2P terminal device 104, and an access node 105 of the terminal devi...
