On the contrary, these embodiments are provided to enable a thorough understanding of the present disclosure, and to fully convey the scope of the present disclosure to those skilled in the art.

(6) A method of sending cell camping information is provided in a first embodiment of the present disclosure, including:

(7) sending system information of a first cell to a terminal, where the system information includes at least two camping thresholds of the first cell, or one camping threshold and at least two threshold offsets of the first cell; the at least two camping thresholds respectively correspond to terminals with different uplink resource access capabilities, and the at least two threshold offsets respectively correspond to terminals with different uplink resource access capabilities.

(8) In the embodiment of the present disclosure, the first cell that supports the uplink supplementary resource (SUL) technology may send system information carrying at least two camping thresholds of the first cell to the terminal, or the first cell that supports the SUL technology may send system information carrying one camping threshold and at least two threshold offsets of the first cell to the terminal.

(9) In the embodiment of the present disclosure, the system information carrying at least two camping thresholds of the first cell or one camping threshold and at least two threshold offsets of the first cell are sent to the terminal through broadcasting.

The at least two camping thresholds correspond to terminals with different uplink resource access capabilities, thereby further enabling the terminal to select or determine the corresponding cell camping threshold based on its support capability for SUL technology (i.e., the uplink resource access capability) and camp on a cell based on the selected or determined cell camping threshold, so that the terminals with different uplink resource access capabilities may camp on the most suitable cell based on the uplink resource access capabilities thereof.

The specific determination method is: if the threshold information of new cell is broadcasted in the current cell, the terminal obtains the camping threshold information about the new cell (second cell) in the broadcast message, and selects a suitable threshold value according to its uplink resource access capability, and the correspondence between these camping thresholds and different types of terminals, so as to access the second cell according to the uplink resource corresponding to the selected camping threshold.

When a certain condition is meet, the terminal considers that the new cell can be a reselection candidate cell, otherwise the terminal considers that the new cell cannot be camped on. For example, when the “value of measurement result of the uplink resource access capability of the terminal” is greater than the “camping threshold+threshold offset”, the terminal considers that the second cell can be a reselection candidate cell and may further reselect and access the second cell.
