Embodiment Construction

[0026] In a P2P overlay network, SNs can communicate with each other through Resource Location and Discovery (RELOAD, Resource Location and Discovery) messages to complete operations such as connection and data storage, while mAGCF is only responsible for sending and receiving messages, not For data storage and message routing, etc.

[0027] In the scheme of the present invention, the function of the existing mAGCF is expanded so that it can store the routing table information sent by the connected SN, and can select and connect the new routing table information according to the routing table information when the connected SN has a problem. The SN.

[0028] image 3 It is a flowchart of an embodiment of a method for processing a call request in a P2P overlay network according to the present invention. Such as image 3 shown, including the following steps:

[0029] Step 31: The mAGCF periodically receives the routing table information sent by the connected SN, assuming it i...

Abstract

The invention discloses a call request processing method in a peer to peer (P2P) overlay network. The method comprises the following steps: receiving routing table information which is connected and sent by a unimolecular nucleophilic substitution (SN1) by mAGCF periodically and storing the latest routing table information, wherein the routing table information comprises related node information of the SN1, and selecting a usable related node bimolecular nucleophilic substitution (SN2) from stored related nodes, building connection with the SN2 and using the SN2 to finish a call when a call request sent by a terminal is received and the SN1 is confirmed to be wrong. The invention further discloses a P2P overlay network system and a mAGCF. Call success rate is improved.

Description

technical field [0001] The present invention relates to network technology, in particular to a call request processing method, system and device in a peer-to-peer (P2P, Peer to Peer) overlay network. Background technique [0002] In the existing P2P overlay network, the mobile access gateway control entity (mAGCF, Mobile Access Gateway Control Function) needs to be used to convert and transmit messages between the circuit domain terminal and the super node (SN, Super Node), so as to Access the CS domain terminal to the PS domain. [0003] figure 1 It is a schematic diagram of the composition and structure of the existing P2P overlay network system. Such as figure 1 As shown, it mainly includes: mAGCF, terminal and SN; among them, the terminal can be divided into a circuit domain terminal and a packet domain terminal, a circuit domain terminal can be a 2G terminal or a 3G terminal, etc., and a packet domain terminal can be a session initiation protocol (SIP, Session Initi...
