Abstract: A method performed by a communication device for determining an extended time period related to a signalling message between a core network node and the communication device in a wireless communications network, the method comprising: obtaining (301) an indication of a coverage capability of the communication device; obtaining (302) an indication of a time period, which time period is related to the signalling message; and determining (303) the extended time period related to the signalling message, based on the indication of the coverage capability of the communication device and based on the indication of the time period.

Abstract: A positioning node (e.g., SMLC), a Radio Access Network (RAN) Node (e.g., BSS/BTS), and a wireless device (e.g., MS) are described herein which implement procedures and corresponding modified or new messages/information elements/fields to reduce the possibility of a bandit (e.g., invalid or unauthorized) wireless device from triggering the RAN Node (e.g., BSS/BTS) to generate false timing advance (TA) information associated with the wireless device and report the false TA information to the positioning node (e.g., SMLC) which leads the positioning node (e.g., SMLC) to estimate with degraded accuracy a position of the wireless device.

Abstract: A mechanism is described herein for enhancing the radio coverage for a wireless device based on an exchange of uplink and downlink radio condition information, referred to as uplink and downlink Radio Coverage Category (RCC) values, between the wireless device and a network (e.g., a Radio Access Network (RAN) node, Core Network (CN) node) for use in data transmission (e.g., control plane related signaling or user plane related payload transmission).

Abstract: A radio access network node (e.g., Base Station Subsystem, Evolved Node B) and method are described herein for indicating to a core network node (e.g., Serving GPRS Support Node, Mobility Management Entity, CIoT Serving Gateway Node) usage of exception reports by a mobile station. In addition, a core network node (e.g., Serving GPRS Support Node, Mobility Management Entity, CIoT Serving Gateway Node) and method are described herein for receiving an indication of usage of exception reports by a mobile station.

Abstract: A wireless communication device sends positioning messages on the random access channels in two or more cells of a wireless communication network, where the messages exhibit one or more characteristics enabling the network to differentiate them as positioning messages rather than access messages (604). Correspondingly, the network uses the received messages as a basis for estimating timing advance values for the device with respect to the two or more cells (606), and it commonly links the cell-specific timing advance values to a device identifier included in the positioning messages by the device (608). The inclusion of the device identifier allows a positioning node to recognize the timing advance values as being associated with the same wireless communication device, for use in multilateration-based positioning estimation.

Abstract: A radio access network node (e.g., base station subsystem) and method are described herein for indicating to a mobile station (e.g., CIoT device) which system information (SI) message(s) (if any) has changed relative to the mobile station's last reading. In addition, a mobile station (e.g., CIoT device) and method are described herein for receiving an indication that indicates which system information (SI) message(s) (if any) has changed relative to the mobile station's last reading.
