A network device generates an occurrence indication for indicating a subsequent occurrence of access information. Then, the network device transmits the occurrence indication in association with a system signature. The system signature indicates a part of the access information for use by a terminal device in accessing the network device. The power consumption of the terminal device in receiving the access information based on the occurrence indication can be reduced efficiently. ## Claims ### Claim 1 A method implemented at a network device, comprising: generating an occurrence indication for indicating a subsequent occurrence of access information, wherein the access information comprises an access information table that indicates a paging procedure through which a terminal device reaches the network device, and where generating the occurrence indication comprises: generating an indicator as to whether the subsequent occurrence of the access information is between a current occurrence and a subsequent occurrence of a system signature, and wherein receipt of the indicator of no occurrence of the access information between the current and subsequent occurrences causes the terminal device to be idle;
