The invention inter alia relates to a method, performed by a first apparatus, for positioning or assisting in positioning said first apparatus, said method comprising: obtaining multiple original identifiers identifying respective first radio networks or nodes thereof; generating, for each of at least two of said original identifiers, from a respective original identifier a shortened identifier being representative of said respective original identifier and having a smaller size than said respective original identifier; and providing said shortened identifiers over a second radio network for positioning or assisting in positioning said first apparatus.

A method for electronic device identifier assignment at a host computing device includes receiving a current local identifier of a separate electronic device and a full unique identifier of the separate electronic device. A host-specific identifier is assigned to the separate electronic device by, based at least in part on determining that the current local identifier of the separate electronic device is included in a set of local identifier values available for assignment, assigning the host-specific identifier to the separate electronic device with a same local identifier value as the current local identifier. Based at least in part on determining that the current local identifier of the separate electronic device is already assigned by the host computing device to a different separate electronic device, the host-specific local identifier is selected from the set of local identifier values available for assignment and assigned to the separate electronic device.

This disclosure describes an IP address allocation method and apparatus, and a system. Specifically, when there is a relay device between an address request device and an address allocation device, and the address request device requests an IPv6 address, a request packet sent by the address request device to the address allocation device includes an interface identifier negotiated with the relay device. After receiving the request packet, the address allocation device may allocate the IPv6 address based on the interface identifier in the request packet, where the IPv6 address includes the interface identifier; and send the IPv6 address to the address request device by using a response packet.

A method (50) of and a server (19) and network node or client devices (3, 5) communicatively interconnected in a network (1) and arranged for over-the-air, OTA, data upgrade or update of client devices. In the event of a timeout (54) at the server (19) waiting for a response or request message from a selected OTA client (5) during an ongoing OTA data upgrade, the OTA server (19) checks whether a network address change (51) of the selected OTA client (5) caused the OTA server to timeout.

In one embodiment, a method includes receiving a packet comprising a destination address in a destination address field of the packet, where the destination address including at least a first global identifier and a second global identifier, determining that the first global identifier corresponds to the first network apparatus, determining that a local identifier in the destination address is associated with the first global identifier, identifying one or more instructions associated with the local identifier, performing one or more functions instructed by the one or more instructions, updating the destination address in the destination field of the packet to an updated destination address, determining a forwarding rule associated with the packet, and forwarding the packet with the updated destination address based on the forwarding rule.

An apparatus for transmitting and receiving data to/from an IoT device to accelerate the spread of IoT. The IoT device 110 generates a message to be transmitted, and transmits, via SMS, the message to the phone number of a first server 101, which is stored in the IoT device 110. The first server 101 notifies the IoT terminal 110, as needed, of having received SMS data including the message, and thereafter delivers the SMS data to a second server 102. The second server 102 specifies a destination with reference to associations between destination identifiers includable in the SMS data and destinations. The second server 102 transmits, to a third external server 123, a portion obtained by excluding the destination identifier from the message or the whole message including the destination identifier.

A wireless data message generally includes the destination address (such as MAC address) encoded in a field of the data message. A base station must receive the data message and decode the address before the core network can deliver the message to the recipient's cell. For faster communication, certain address messages are disclosed, by which the destination address may be disclosed before the data message is uploaded. Early disclosure of the destination address may enable the core network to deliver the data message to the recipient with fewer delays. In various configurations, the destination address may be provided concurrently with a scheduling request, or combined with a BSR (size) message, or delivered on a random access channel, among other possibilities. For faster uploads, a pointer or code representing the destination address can be specified, resulting in further delay reductions.

A communication method and a communications device, so that both a location and a length of information carried in a data packet header are flexible and variable, the length does not need to be fixed, and the location does not need to be specified. Compared with a conventional protocol, the communication method has stronger flexibility and higher scalability. The method includes: obtaining, by a first device, a data packet, where the data packet includes a first packet header, the first packet header includes first indication information and a value of first packet header information, the first indication information is used to indicate a location of the value of the first packet header information, and the first packet header information is device identification information; and processing, by the first device, the data packet.

A controller assigns variable length addresses to addressable elements that are connected to a network. The variable length addresses are determined based on probabilities that packets are addressed to the corresponding addressable element. The controller transmits, to the addressable elements via the network, a routing table indicating the variable length addresses assigned to the addressable elements. Routers or addressable elements receive the routing table and route one or more packets over the network to an addressable element using variable length addresses included in a header of the one or more packets.
