In one embodiment, a method includes receiving identifier-information from a device of a first user, wherein the identifier-information is associated with a source of an incoming communication; accessing a social graph including nodes and edges, where the nodes include a first node corresponding to the first user, and second nodes corresponding to second users; determining whether one or more reporting users, corresponding to second nodes within a specified degree of separation from the first node, have flagged the source of the incoming communication as a spam source; and sending, to the first user, a spam-notification object that includes information identifying one or more of the reporting users.

A method for processing data transmission services and a terminal are disclosed. The method includes: after a radio link disconnection occurs in a process of only performing the data transmission services of a packet-switched domain in a dedicated state, if judging that a timing value configured with a first timer is 0, a terminal deleting a radio access bearer and a signaling connection of the packet-switched domain; and if judging that a timing value configured with a second timer is not 0, initiating a cell update process, wherein, the first timer is a timer used for monitoring reestablishment of packet-switched domain services; the second timer is a timer used for monitoring reestablishment of circuit-switched domain services. According to the above scheme, the flow of processing a stream interruption of the terminal in a data transmission process can be perfected, and the drawbacks of the existing flow can be solved.

The disclosure relates to a method (30) for radio bearer release performed in a base station node (2) of a communication system (5). The base station node (2) provides one or more radio bearers to a user equipment (1), and the communication system (5) comprises a serving gateway (4). The method (30) comprises: receiving (31) an error message from the serving gateway (4), the error message indicating a faulty radio bearer; awaiting (32), for a delay time, additional error messages indicating faulty radio bearers; and releasing (33) the one or more radio bearers being indicated as faulty.

A method of operating a first electronic device for improving call quality is provided. The method includes the operations of transmitting call data received through a first call between the first electronic device and a third electronic device to a second electronic device, using short-range wireless communication connected with the second electronic device, if a communication abnormality of the short-range wireless communication takes place, connecting a second call between the first electronic device and the second electronic device, generating a third call by merging the first call and the second call, and releasing a call connection of the first electronic device from the third call.

A user apparatus for use in a mobile communication system that supports D2D communication, including: D2D communication means that transmits a D2D signal to another user apparatus by using a resource for D2D communication assigned from a base station in the mobile communication system; and resource control means that transmits, to the base station, a resource release request signal for requesting release of a resource for D2D communication assigned from the base station.

Disclosed are methods, devices, systems, apparatus, servers, computer-/processor-readable media, and other implementations, including a method, performed at a first processor-based wireless device, that includes transmitting at a first time instance, from the first wireless device to a second wireless device, a wireless message including message content, and dynamically determining an adjustable timeout interval based, at least in part, on one or more network characteristics associated with a network comprising the first and/or second wireless devices. The method further includes transmitting at least one subsequent wireless message including at least some of the message content of the wireless message upon a determination that an acknowledgement message responsive to the wireless message transmitted at the first time instance was not received at the first wireless device within a time period, subsequent to the first time instance, greater or equal to the determined adjustable timeout interval.

A method and user equipment (UE) for recovering a service in a wireless network is provided. The method includes detecting, in a UE, that a fast cell update criteria is met, and recovering, in the UE, the service in the wireless network by performing a cell update procedure.

A document processing system includes an embedded controller that has both a local area network interface for receiving documents over an associated network and a wireless personal area network interface for communicating with mobile computing devices using BLUETOOTH low power communications. The embedded controller transmits broadcasts message to nearby mobile computing devices that send responses to the broadcast messages. Based on the RSSI of a received response, the embedded controller can determines whether a particular mobile computing device is in close proximity, indicating that a user is present at the document processing system. The embedded controller sends identification data associated with the document processing system to the mobile computing device. The user of the mobile computing device selects the document processing system to print a document, and the mobile computing device uses the identification data to route the document to the document processing system over a wireless local area network.

Certain aspects of the present disclosure relate to a methods and apparatus for wireless communication. In one aspect, a method of wireless communication comprises receiving, by a long term evolution unlicensed (LTE-U) device, a plurality of signals from an access point on an unlicensed communication spectrum. The method further comprises determining, by the device, whether a signal of the plurality of signals comprises a discovery signal. The method further comprises monitoring a radio link based on, the signal if the signal is determined to comprise the discovery signal.

There is provided an information processing system including a service provider unit, a communication terminal and an information processing unit. The communication terminal includes a terminal first communication section, a terminal second communication section to communicate with the information processing unit through a first communication channel, a terminal third communication section to communicate with the information processing unit through a second communication channel, and a terminal communication control section. The information processing unit includes a unit first communication section to communicate with the communication terminal through the first communication channel, a unit second communication section to communicate with the communication terminal through the second communication channel, a unit communication control section to switch communication channels with the communication terminal from the first communication channel to the second communication channel, and a unit processing section to perform service processing with the service provider unit.
