According to an aspect of the present invention, a communication device includes a communicator for communication with other device in a network to which the communication device belongs and a processor for generating frames to be communicated. The processor generates second identification information different from first identification information which is identification information unique to the communication device based on the first identification information. Further, the processor generates a frame including the second identification information.

A timepiece can acquire time information in a short time, reduce power consumption, and display the correct time. A timepiece comprises a receiver to receive a satellite signal, and a time information generator to generate internal time information. The receiver runs a first reception process that acquires first information including week information from the satellite signal, a second reception process that acquires second information including leap second information from the satellite signal, or a third reception process that acquires third information including hour, minute and second information from the satellite signal. In the first reception timing, after the internal time information is initialized, the receiver runs the first reception process and runs the second reception process after running the first. In a next reception timing, after the first reception timing, the receiver runs the third reception process if the first and second information are acquired in the first reception timing.

Appearance of simultaneous connections is provided to devices that support two wireless protocols which are not permitted to operation simultaneously. As an example the method and systems disclosed are applied to the communication between a phone and a smartwatch wherein Bluetooth (BT) classic protocol is used for e.g. voice commands and phone calls and Bluetooth low Energy (BLE) protocol is used for data notifications. In a first embodiment of the disclosure automatic mode switching between BT and BLE is provided. In a second embodiment a dual-ID device utilizes separate IDs for both protocols in time multiplexed connections. It operates as logically independent devices with individual ID's although physically it is a single device.

An apparatus is provided that includes a processor and a memory storing executable instructions that in response to execution by the processor cause the apparatus to at least perform a number of operations. The apparatus is caused to receive time information over a packet-switched computer network, with the time information including a current standard time, time-zone offset and timestamps that define a predetermined timeframe. The apparatus is caused to calculate a current local time from the current standard time and time-zone offset, and including an adjustment of the current local time in instances in which the timestamps indicate that the current standard time is within the predetermined timeframe. And the apparatus is caused to cause a clock to be set to the current local time.

The embodiments herein relate to a method in a mobility management node for handling information in a network. The node is associated with a wireless device being served by a serving network. The node obtains information about that at least one of the serving network and a time zone and a UCI, has been changed for the device, and information about that the change has not been transmitted to a SGW. When at least one of the serving network and the time zone and the UCI, has been changed, and information about the change has not been transmitted to the SGW, the node transmits the information about at least one of the changed serving network and time zone and UCI, to the SGW, enabling the SGW to forward this information to a PGW.
