Terminal access method, network equipment and communication system

Abstract

The invention discloses a terminal access method, network equipment and a communication system, which relate to the field of communication and aim to solve the problem that a plurality of terminals with the same identifier cannot access a network at the same time. The technical scheme provided by the invention is that: when an accessed terminal which has the same public identifier as a terminal to be accessed exists in the network, a control network element acquires the public identifier, serving as shared information of the plurality of terminals, of the terminal to be accessed; and the control network element accesses the terminal to be accessed to the network according to public identifier, serving as shared information of the plurality of terminals, of the terminal and continues to supply service to the accessed terminal. The embodiment of the invention can be applied to communication systems such as a Gsm edge radio access network (GERAN), a universal terrestrial radio access network (UTRAN) or an evolved universal terrestrial radio access network (E-UTRAN) so as to realize application of machine to machine (M2M) and the like.

Description

technical field [0001] The present invention relates to the communication field, in particular to a terminal access method, network equipment and a communication system. Background technique [0002] Under the existing communication architecture, such as in 3GPP and non-3GPP networks, when a terminal to be accessed requests to access the network, if there is an accessed terminal with the same public identity as the terminal to be accessed in the network, it is necessary to Deleting the access information (such as mobility management information and / or session management information, etc.) of the accessed terminal from the network, that is, terminating services for the accessed terminal, and separating the accessed terminal from the network; And regenerate access information for the terminal to be accessed according to the public identifier of the terminal to be accessed, and access the terminal to be accessed to the network. [0003] For example, in networks such as Long Te...

Problems solved by technology

[0003] For example, in networks such as Long Term Evolution (LTE), when multiple terminals with the same public identity request to access the network, the network side cannot implement the simultaneous access of the multiple terminals with the same public identity to the network , so that it cannot meet the needs of applications such as machine-to-machine (Machine To Machine, M2M)
