Provided in one disclosure of the present specification is a method for transmitting a detection signal from user equipment (UE). The method comprises the steps of: driving a mobility management (MM) delay time timer, when the MM delay time timer is received by the UE from a mobility management entity (MME) in a network; confirming the priority for detecting at least one other UE, when detection of the at least one other UE is required before the MM delay time timer expires; and randomly selecting a resource based on a shared resource pool included in system information, which is broadcasted from a base station, and then transmitting to the at least one other UE a detection signal including a proximity service code from the randomly selected resource, when the detection of the at least one other UE is considered to have high priority or to be urgent.

In a case where wireless connection to a device fails because the number of terminals in wireless connection with the device has reached a maximum number, a communication apparatus instructs the device to stop operating in a direct wireless communication mode.

Measures are provided for management of RRC for D2D communication. Such measures include setting a connected state of RRC for device(s) of a pair of devices. For the devices(s), both a D2D communication service between the pair of devices and a core network communication service between the device(s) and a core network entity are active. The setting enables radio resource management for the device(s) for the D2D communication service and the core network communication service. Termination of the core network communication service is detected for the device(s). A connection towards the core network entity is reconfigured for disabling the core network communication service of the device(s). The connected state of RRC is maintained for the devices(s) of the pair of devices, for which the device(s) only the device-to-device communication service is active. The maintaining enables radio resource management for the device(s) for the D2D communication service.

The disclosure provides a Radio Resource Management (RRM) method, device and system. The method includes that: a first network element judges whether a target Evolved Universal Terrestrial Radio Access Network NodeB (eNB) of a terminal is a configured eNB or not, wherein the configured eNB is an eNB pre-storing context information of the terminal; and under the condition that the target eNB is the configured eNB, the first network element sends a notice of performing communication according to the corresponding context information to the configured eNB and the terminal respectively. By the disclosure, problems of serial Handover (HO) in a related technology are solved, and an effect of increasing an HO success rate is achieved.

Methods and apparatus, including computer program products, are provided for delaying a service request. In one aspect there is provided a method. The method may include receiving, at a user equipment, a message including a service rejection sent by a network; starting a timeout period in response to the received message including the service rejection; and waiting to send an attach request to the network until at least one of a radio resource control connection release is received from the network or the timeout period expires. Related apparatus, systems, methods, and articles are also described.

The power consumption of a mobile station is reduced according to the conditions of use by a user without stopping packet communication necessary for the user. In a program for a base station apparatus, a request for establishing radio connection and information indicating the conditions of use of the mobile station apparatus are acquired from the mobile station apparatus (step S1). When the information indicating the conditions of use indicates the use of the mobile station apparatus, a first timer is set for a relatively long time whereas when the information indicating the conditions of use indicates the non-use of the mobile station apparatus, the first timer is set for a relatively short time. When the transmission of a packet to the mobile station apparatus is completed (step S4), the first timer is started up (steps S6 and S7), and when the first timer expires, a control signal is transmitted to the mobile station apparatus (step S8) to interrupt the radio connection to the mobile station apparatus (step S11).

The present disclosure relates to balancing load amongst different capillary-cellular gateways (24) to indirectly account for load attributable to self-managed devices (27) that are not directly managed by a management node (28). Embodiments include a method implemented by a management node (28) that directly manages managed device(s) (26) in capillary network(s) (16). The method comprises determining, for each of the managed device(s) (26), a weight metric that describes a collective load attributable to not only the managed device (26) but also to any self-managed devices (27) that connect to the cellular network (15) via the managed device (26). The method also comprises balancing load amongst the capillary-cellular gateways (24) based on the weight metrics, by requesting that at least one managed device (26) move its entire collective load to a different capillary-cellular gateway (24) or reduce its weight metric by shedding load.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for deactivating SCells during SCG change procedure in the wireless communication system, the method comprising: configuring a PCell (Primary Cell) in a master base station (BS) and a PSCell (Primary-Secondary Cell) and one or more SCells (Secondary Cells) in a secondary BS; receiving an RRC (Radio Resource Control) reconfiguration message indicating a SCG (Secondary Cell Group) change procedure while maintaining a connection with the master base station; and deactivating the one or more SCells in the secondary BS if the PSCell is not changed by the SCG change procedure.

A method for controlling disconnection during a call, and a terminal are provided. The method used during the call made between a first terminal and a second terminal includes the following steps that: the first terminal detects a hang-up event generated by a hand-up operation of a local user; the first terminal determines whether or not the second terminal is a controlled terminal included in a preset controlled terminal list; and the first terminal ignores the hang-up event and rejects to send a disconnection message to a network side if the second terminal is a controlled terminal included in the preset controlled terminal list.

Disclosed is a method and system for release of a UE's context record in response to failure of air interface communication. As disclosed, a wireless communication system includes a base station that has a protocol stack defining a series of logical processing layers through which the base station sequentially processes data for transmission to a UE. The layers include an upper layer and a physical layer at which the base station processes the data for communication over an air interface to the UE. Accordingly, the base station detects failure of air interface communication between the base station and the UE. In response to detecting the failure, and without waiting to detect at the upper layer a further failure corresponding with the failure of the air interface communication, the base station transmits to a network controller a UE-context release request requesting release of bearer context that was established for the UE.
