Embodiment Construction

[0061] The methods and devices disclosed herein provide an improvement over access class barring, where radio resource consumption is specifically considered, thereby mitigating potential congestion in cells with user equipment that can perform transmissions to radio network nodes. Blind repeat, repeat or retransmit.

[0062] There may be various reasons for using blind repetition: for example, the device is deployed in challenging conditions (such as in the basement of a building), the device has a small form factor, or is ultra-low cost such that the radio characteristics of the device are Sub-optimal (such as using a small non-ideal antenna); or, for example, the device uses lower output power to access the network.

[0063] NB-IoT devices in extended coverage may use 128 repetitions to access the system on the NB-IoT Physical Random Access Channel (NPRACH), ie the physical channel used for initial system access, eg under extreme radio conditions. For devices in normal rad...

Abstract

Methods and apparatus are proposed for controlling a radio access network connection to a telecommunications network. In order to enable resource based access barring a wireless terminal performs a delay in proceeding with a radio network access procedure based on an obtained indication of access barring. The access barring is a resource based access barring; based on the resource usage of a wireless terminal.

Description

technical field [0001] The present application relates to a method and a device for postponing a network access procedure for connecting to a telecommunications network. Background technique [0002] 3GPP Release 13 introduces a new radio access technology called Narrowband Internet of Things (NB-IoT), which aims to provide machine-to-machine type connectivity. In the same release, Long Term Evolution (LTE) enhancements (UE category M1) for machine type communication (eMTC) including bandwidth-reduced low-complexity (BL) user equipment (UE) types are specified. Also, for GSM, a new solution called EC-GSM-IoT is specified, which is intended to serve Internet of Things (IoT) type services. A NB-IoT device or MTC device connected to a telecommunication network via radio transmission may be considered to include a wireless terminal; herein, reference to a wireless terminal shall include any NB-IoT device or MTC device unless expressly stated to the contrary. [0003] What the ...
