Embodiments herein relate to a method performed by a network node (13) for handling communication of a wireless device (10) in a wireless communication network (1). The network node (13), such as an MME, pages the wireless device (10) using a first paging channel; and pages the wireless device (10) using a second paging channel, wherein paging the wireless device (10) using the first paging channel comprises selecting one or more radio network nodes to page the wireless device (10) using the first paging channel based on information relating to current knowledge of a location of the wireless device (10).

A base station causes a radio terminal to transition to a specific state. The specific state is a state in which signaling for the radio terminal is suppressed compare to an RRC connected state while a connection for the radio terminal is maintained between the base station and a core network. The base station transmits to an entity of the core network, an identifier identifying the radio terminal and a first RRC transition notification indicting that the radio terminal transitions from the RRC connected state to the specific state. The base station causes the radio terminal to transition from the specific state to the RRC connected state. The base station transmits to the entity, a second RRC transition notification indicting that the radio terminal transitions from the specific state to the RRC connected state.

Embodiments of this application provide a plurality of mobile network optimization processing methods, devices, and systems. Joint optimization is performed at an application layer and a communications layer, and information provided by the application layer is used to instruct UE to perform proper state transition, to optimize a state transition process of the UE, and reduce resource consumption caused during state transition of the UE.

A method includes determining a parameter of a coverage enhancement policy employed by a communication system. The method also includes setting a timing configuration (371-373, 391-393, 605, 606) of a discontinuous reception cycle (370-2, 370-3) employed by a terminal (101) of the communication system depending on the parameter. The method also includes communicating a paging signal in accordance with the timing configuration (371-373, 391-393, 605, 606) of the discontinuous reception cycle (370-2, 370-3) and the coverage enhancement policy.

The present disclosure discloses a portable apparatus which communicates with a vehicle through a wireless network, obtains vehicle information as the wireless network is connected, determines whether a user boards the vehicle based on motion state data of the user and the vehicle information, determines a stop to provide notification based on whether the user boards the vehicle and a getting-off history, and outputs getting-off notification.

Embodiments of a user equipment (UE) and method for resource allocation and device-to-device (D2D) discovery hopping are generally described herein. In some embodiments, the UE may receive signaling from an enhanced node B (eNB) indicating discovery resources to transmit discovery signals on within an LTE operation zone. The discovery resources may include a discovery zone which may comprise a plurality of physical resource blocks (PRBs) and a plurality of subframes. The UE may transmit a discovery signal for receipt by one or more other UEs for D2D discovery within some of the PRBs of the discovery zone. The PRBs for the transmission of the discovery signal may be determined in accordance with a hopping mode to provide increased frequency diversity within a bandwidth of the discovery zone. The hopping mode may comprise intra-subframe hopping, inter-subframe hopping or joint intra/inter-subframe hopping.
