TECHNICAL FIELD

The present disclosure relates to, but is not limited to, the field of radio communications and, in particular, relates to a method for obtaining a network system resource configuration, a terminal, a network device and a system.

BACKGROUND

With the development of wireless communication technologies, in the research of 5th Generation (5G) mobile communication technology, narrowband-Internet of things (NB-IoT), a research sub-topic of machine type communication (MTC), has been proposed. The NB-IoT provides a low-throughput wireless communication service in a 200 kHz spectral bandwidth for low-cost user equipment (UE).

In the existing art, a single-carrier cell within the 200 kHz spectral bandwidth has a small capacity, and is difficult to support the traffic transmission of a large number of NB-IoT terminals. Therefore, a multi-carrier cell strategy is introduced, that is, multiple single-carrier cells covered in the same area under the same base station are aggregated into a multi-carrier cell. The multiple single-carrier cells share one physical cell identifier, and transmit a broadcast channel and a synchronization channel on one single carrier, this single carrier is called an anchor carrier, and other multiple single carriers are used for providing the uplink and downlink traffic channel transmission and these multiple single carriers are called non-anchor carriers.

SUMMARY

The applicant finds that, in the implementation of the multi-carrier cell strategy, a large number of terminals simultaneously monitor pages or initiate the random access, but each of the terminals can only monitor pages or initiate the random access on one single carrier, causing that the paging and random access capacity of a network device is poor.
