Access Method of Wireless Communication Network

摘要

An access method of a device (10) such as an MTC device to a network (20, 30, 40) which allows the transmission of small data packets without the need to read all the System Information normally required to make an initial network access. The device (10) may notify the network that an access request is occurring from a device that was either specifically allowed to use a stored access configuration or is accessing the cell using modified system information being broadcast by the cell. Such notification may be implicit in the characteristics (choice of preamble, timing, frequency and/or repetition) of the access request. The network, preferably having knowledge of the method being used by the device to access the network, can either reject this access or accept it depending on whether the access was from a stored configuration or read from System Information.

1. A method of accessing a wireless communication network, comprising:
the network broadcasting system information specifying access parameters for gaining access to the network; a device which needs access to the network deciding whether to use a stored configuration of the access parameters, and if so:
transmitting an access request to the network on the basis of the stored configuration; andindicating use of the stored configuration; and the network deciding whether or not to accept the access request.
