Instant communication system, access equipment and communication equipment

The invention discloses an instant communication system, access equipment and communication equipment. The system comprises the access equipment and the at least one piece of communications equipment; the access equipment is used for judging whether the distance between the communication equipment and the access equipment reaches a preset access distance when accessing to a network or not; and if the distance reaches the preset access distance, the communication equipment accesses to the network through the access equipment so as to realize instant communication between the communication equipment and other communication equipment in the network. Due to the application of the instant communication system, a user is not required to perform password authentication in the preset access distance range allowable to access to the network when accessing to the network by means of the communication equipment and can access to the network, so that the instant communication is performed, the flow that the communication equipment accesses to the network is greatly simplified, and convenience is brought to the user.
