Embodiment Construction

[0020] figure 1 It is a schematic diagram of the application environment of the peer-to-peer instant messaging system according to an embodiment of the present invention. The mobile terminals UE A, UE B and UE C may be wirelessly connected to a base station or a node B, and the node B is connected to the core network 6 via a radio network controller (RNC) 5, and the user terminals UE A, UE B and UE C are connected by The Base Transceivers (Node Bs) and the Radio Network Controller 5 form the UMTS Terrestrial Radio Access Network (UTRAN) to exchange information.

[0021] If the user terminal UE A wants to establish peer-to-peer communication with the user terminal UE B, the calling user terminal UE A that requests peer-to-peer communication first sends a peer-to-peer call request to UTRAN through the uplink control channel, in Koninklijke Philips Electronics N.V. in 2003 In the invention of patent No. 03119895.3, titled "Method and apparatus for establishing and maintaining ra...

Abstract

The invention proposes a method of peer-to-peer instant messaging and the mobile terminal thereof, which could make the mobile terminal to establish and maintain a list of friend users and update the connection status of the friend users timely. The method of peer-to-peer instant messaging includes following steps: receiving the list of on-line users with capability of peer-to-peer instant messaging sent by the radio network; comparing said list of particular users with said received list of on-line users; updating, according to said comparison result, the connection status record of each user in said list of particular users so that the mobile terminal could establish a peer-to-peer instant messaging with at least one user mobile terminal in said list of particular users according to said updated connection status record. The present invention enables the user to establish peer-to-peer connection more effectively and to perform instant messaging while occupying less network resources.

Description

technical field [0001] The present invention relates to instant messaging (IM), and more particularly, to a peer-to-peer (P2P) instant messaging method and device in a radio network. Background technique [0002] Instant messaging is used to enable users in a network, such as the Internet and other mobile radio networks such as GSM, CDMA, to chat or transfer information in real time in the form of words or other information. At the same time, the instant messaging system can promptly notify each online user of the online / offline status of the users in its contact list. [0003] A conventional instant messaging system adopts a client / server structure mode, and in the peer-to-peer communication mode, real-time chatting or information transfer can be directly performed between two or more mobile terminals without involving a base station. For establishing peer-to-peer instant messaging between two mobile terminals, US Patent Publication No. 2003 / 0182428A1 (inventors are Jiang ...
