Abstract: A base station transmits a paging message carrying a contention-free early-data transmission indication to a user equipment, and transmits a random access response message carrying early downlink data to the user equipment in response to a random access request message transmitted by the user equipment in a random access procedure. A base station transmits a paging message carrying a contention-based early-data transmission indication to the user equipment, and transmits an RRC response message carrying early downlink data to the user equipment in response to an RRC request message transmitted by the user equipment in a random access procedure. In a random access procedure, user equipment generates and transmits a scheduling request message to a base station after receiving early downlink data transmitted by the base station, and transmits uplink data corresponding to the early downlink data to the base station according to an uplink grant transmitted by the base station.

Abstract: An intercepting user equipment and a lawful interception method thereof are provided. The intercepting user equipment registers to the administrating server for lawful interception, and then receives a positive interception message from the administrating server. The intercepting user equipment receives a signal from user equipment, and determines whether a power measurement of the signal exceeds a threshold. If positive, the intercepting user equipment transmits a power adjustment request to the administrating server so that the administrating server notifies the eNB of transmitting a power adjustment command to the user equipment for adjusting transmitting power. The intercepting user equipment intercepts communication data of the user equipment.

Abstract: A direct-mode communication system includes a first client direct-mode communication apparatus and a first backhaul network. The first client direct-mode communication apparatus transmits a proximity notification request to a second backhaul network via the first backhaul network so that the second backhaul network returns a proximity notification acknowledgement (ACK) signal. The first backhaul network receives a piece of first client location information and a piece of second client location information from the first direct-mode communication apparatus and the second backhaul network respectively, and determines a location relationship accordingly. The first backhaul network transmits a Wi-Fi connection signal to the first client direct-mode communication apparatus according to the location relationship. The first client direct-mode communication apparatus establishes a direct-mode communication connection with a second client direct-mode communication apparatus according to the Wi-Fi connection signal.

Abstract: A user equipment and cell re-selection estimation method thereof for use in a NB-IoT communication system are provided. The user equipment selects a cell re-selection criterion according to a user equipment status, and determines whether a serving RSRP value of a serving base station is greater than a re-selection threshold value based on the cell re-selection criterion. The user equipment performs cell re-selection when the serving RSRP value is greater than the re-selection threshold value. The user equipment does not perform the cell re-selection when the serving RSRP value is not greater than the re-selection threshold value.

Abstract: A user equipment (UE), a mobile hotspot equipment, a backhaul device and a method for establishing a path loss model database are provided. The UE receives a wireless signal from a first surrounding mobile hotspot equipment, and measures the wireless signal during a time interval so as to generate received signal information corresponding to the wireless signal. Thereafter, the UE transmits a measurement response message that includes an identity of the first surrounding mobile hotspot equipment and the received signal information to the backhaul device via the mobile hotspot equipment. Accordingly, the backhaul device establishes a path loss model according to the received signal information and stores the path loss model into a path loss model database.
