摘要： A method performed by a node (111) supporting operation on a Constrained Application Protocol (CoAP), but incapable of supporting operation on a Domain Name System (DNS) protocol. The node (111) encodes (402) a DNS query into a first message (601, 701), which has a format supported by the CoAP. The DNS query is mapped to the CoAP format of the first message (601, 701) based on a mapping scheme. The node (111) then initiates sending (403) the first message (601, 701) to another node (112) operating in the communications network (100). The another node (112) supports operation on the CoAP and on the DNS protocol. The node (111) finally receives (404) a second message (620, 706) from the another node (112), which has the format supported by the CoAP. The second message (620, 706) comprises the DNS response to the sent DNS query. The DNS response is mapped to the CoAP format of the second message (620, 706) based on the mapping scheme.

摘要： A Lightweight Machine to Machine (LwM2M) client device (800) is disclosed. The client device comprises processing circuitry configured to cause the LwM2M client device to expose, to a LwM2M server, a first resource of a LwM2M management data object that is hosted at the LwM2M client device, wherein a value of the first resource indicates when the LwM2M client device will next enter an awake mode of operation following a period of time spent in a sleep mode of operation (110). The processing circuitry is also configured to cause the LwM2M client device to enter a sleep mode of operation (120) and enter an awake mode of operation at a time corresponding to a value of the first resource (130). Also disclosed are a LwM2M server device (900), and methods (100, 300) performed by a LwM2M client and a LwM2M server.

摘要： A machine device (100), a Machine-to-Machine, M2M, server (102) and methods therein are provided, where the machine device (100) connects to a wireless access gateway (GW1) in order to perform an M2M communication. The machine device (100) detects (1:1) a set of reachable wireless access gateways (GW1-GW4) with which the machine device (100) is able to reach for communication using short range wireless technology, and sends (1:2) identifiers of the reachable wireless access gateways to the M2M server (102). The M2M server (102) then sends (1:4) an indication of at least one prioritized wireless access gateway (GW1, GW2) selected (1:3) from the reachable wireless access gateways. Thereby, the machine device (100) is able to connect (1:5) to one of the prioritized wireless access gateway(s) (GW1) for performing the M2M communication provided that this wireless access gateway is available.

摘要： Methods and devices for mitigating Distributed Denial-of-Service (DDoS) attacks are provided. A first computing device operable to mitigate DDoS attacks includes processing circuitry configured to generate a DDoS Open Threat Signalling, DOTS, client identifier for the first computing device. The processing circuitry is further configured to initiate transmission of a request message to a second computing device, wherein the request message requests the registration of the first computing device and includes the DOTS client identifier for the first computing device. The processing circuitry is further configured to receive a response message from the second computing device, sent in response to the second computing device receiving the request message. Both the first computing device and second computing device are Constrained Application Protocol, CoAP, endpoints, and the request message and response message are transmitted via a DOTS signal channel.
