An electronic data communication network includes source terminal nodes connected to the network; moving c-nodes; and one or more destination terminal nodes connected to the network. The source terminal nodes send IP packets over the c-nodes to the destination terminal nodes to accomplish arbitrary communications between arbitrary groups of the source terminal nodes to arbitrary groups of the destination terminal nodes. The moving node comprises a mobile communication device. The moving node comprises a starting node that sends the data, a relay node that relays the data, and an ending node that receives data. A virtual circuit is formed along a path comprising the relay nodes for data communication. The virtual circuit is identified by the path. Routing of data from the starting node to the ending node is performed with P2P routing algorithm.

The at least one personal device is adapted to be worn by individuals and is configured to transmit short-range wireless broadcast signals. The personal device is configured to establish a short-range wireless communication link with the nodes of the self-organizing network and to enable the establishment of a short-range wireless communication link with a mobile communications device which may be associated with the personal device. The network and the personal devices are further configured to enable handover of the personal device between a node of the self-organizing network and a mobile communications device which may be associated with the personal device.

A multi-member Bluetooth device includes: a main Bluetooth circuit capable of directly communicating with a remote Bluetooth device through a Bluetooth transmission approach; and an auxiliary Bluetooth circuit capable of indirectly communicating with the remote Bluetooth device through the main Bluetooth circuit. After operating for a certain period, the main Bluetooth circuit transmits the main Bluetooth circuit's device identification data and multiple Bluetooth connection parameters between the main Bluetooth circuit and the remote Bluetooth device to the auxiliary Bluetooth circuit. When received instructions from the main Bluetooth circuit, the auxiliary Bluetooth circuit utilizes the device identification data and the multiple Bluetooth connection parameters transmitted from the main Bluetooth circuit to directly communicate with the remote Bluetooth device through a Bluetooth transmission approach by imitating the main Bluetooth circuit, and the main Bluetooth circuit then indirectly communicates with the remote Bluetooth device through the auxiliary Bluetooth circuit.

A multi-member Bluetooth device includes: a main Bluetooth circuit capable of bidirectionally communicating with a remote Bluetooth device through a first Bluetooth communication circuit; and an auxiliary Bluetooth circuit capable of communicating with the main Bluetooth circuit through a data transmission circuit. While the main Bluetooth circuit utilizes the first Bluetooth communication circuit to communicate with the remote Bluetooth device, the auxiliary Bluetooth circuit utilizes a second Bluetooth communication circuit to sniff packets transmitted from the remote Bluetooth device. When detected that the auxiliary Bluetooth circuit has missed packets transmitted from the remote Bluetooth device, the main Bluetooth circuit transmits missing packets of the auxiliary Bluetooth circuit to the auxiliary Bluetooth circuit through the data transmission circuit.

The present disclosure discloses an adaptive antenna switching system and switching method, and an intelligent terminal, the method comprises obtaining a first antenna module corresponding to a first front-end module; and when the first antenna module meets a switching condition, matching the first front-end module with the first antenna module match, and performing data interaction through the first antenna module. The antenna module in the present disclosure is capable of adaptive adjustment according to a usage condition of a user, which ensures that an antenna state can be dynamically switched in real time when one or more antenna modules therein exhibit severe signal attenuation or abnormal signal interruption within a period, thus ensuring that wireless performance of the first front-end module currently used by a user is maintained at an optimal level, and improving user experience of the intelligent terminal.

The present invention relates to a method and an apparatus for connecting a first device to a second device using Bluetooth low energy (LE). According to the present invention, provided are a method and an apparatus which receive, from the second device, a first advertising message comprising first interval information indicative of the transmission interval of the advertising message; adjust the size of a scan window for searching for peripheral devices on the basis of the first advertising message; receive a second advertising message from the second device or an external device via the scan window; and establish a Bluetooth LE connection with the second device if the transmission interval indicated by the interval information is the same as the interval at which the first advertising message and the second advertising message are transmitted.

A communications method of a wearable device, a communications system, and a related device are disclosed, which are applied to a communications technology field. In the communications method of a wearable device, if a second BLUETOOTH connection between user equipment and the wearable device is disconnected, a first BLUETOOTH connection between a network connection device and the wearable device is established, so that the network connection device may send, to the wearable device through the first BLUETOOTH connection, first information sent by the user equipment through a third communication connection to the network connection device. In this way, indirect communication between the user equipment and the wearable device is implemented by using the network connection device, so that the user equipment and the wearable device are not limited by a communication range.

A wearable device, such as a smartwatch, may be used to enable switching of network services between endpoints. The switching of network services may include transferring the telephone number associated with a user's account to a particular active device, selected from a number of possible devices, of the user. The switching may be based on a number of factors and coordinated through the wearable device. The factors may include, for example, the location of the user, the location of the user relative to the user's endpoints, user provided priority information, and/or other user-specified profile information relating to endpoint preferences.
