Access Method of Wireless Communication Network
First Claim
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; and
indicating use of the stored configuration; and
the network deciding whether or not to accept the access request.

Abstract
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.

12. A wireless communication system, comprising:
-
a base station arranged to broadcast system information specifying access parameters for gaining access to the system; and a device arranged to determine a need for access to the system, to decide whether to use a stored configuration of the access parameters for an access request, and if so, to transmit the access request to the base station on the basis of the stored configuration and indicate use of the stored configuration;
whereinthe base station is arranged to receive the access request and the indication, and to decide whether or not to accept the access request.

13. A base station for use in a wireless communication network, the base station arranged to:
-
broadcast system information specifying access parameters for gaining access to the network; receive, from a device wishing to access the network, an access request and an indication of whether or not a stored configuration of the access parameters has been used for the access request; and decide whether or not to accept the access request taking into account the indication.

14. A device for use as a terminal in a wireless communication network, the device arranged to:
-
receive at least part of broadcast system information specifying access parameters for gaining access to the network; determine a need for access to the system, decide whether to use a stored configuration of the access parameters for an access request, and if so, to transmit the access request to the network on the basis of the stored configuration and indicate use of the stored configuration.

15. One or more non-transitory computer-readable recording media storing computer-readable instructions which, when executed by a processor of a base station in a wireless communication network, perform the functions of:
-
broadcasting system information specifying access parameters for gaining access to the network; receiving, from a device wishing to access the network, an access request and an indication of whether or not a stored configuration of the access parameters has been used for the access request; and deciding whether or not to accept the access request taking into account the indication.

-
receiving at least part of broadcast system information specifying access parameters for gaining access to the network; determining a need for access to the system, decide whether to use a stored configuration of the access parameters for an access request, and if so, to transmit the access request to the network on the basis of the stored configuration and indicate use of the stored configuration.
