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 network node, a device and methods therein are provided for handling of devices based on group membership. The method performed by the network node comprises obtaining of information indicating a group membership and further indicating reachable gateways of a set of devices. The method further comprises initiating a command to a number of devices out of the set of devices belonging to the same group, G1, to connect to one of the indicated gateways, gateway W, selected for the number of devices based on group membership.

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： The present disclosure relates to balancing load amongst different capillary-cellular gateways (24) to indirectly account for load attributable to self-managed devices (27) that are not directly managed by a management node (28). Embodiments include a method implemented by a management node (28) that directly manages managed device(s) (26) in capillary network(s) (16). The method comprises determining, for each of the managed device(s) (26), a weight metric that describes a collective load attributable to not only the managed device (26) but also to any self-managed devices (27) that connect to the cellular network (15) via the managed device (26). The method also comprises balancing load amongst the capillary-cellular gateways (24) based on the weight metrics, by requesting that at least one managed device (26) move its entire collective load to a different capillary-cellular gateway (24) or reduce its weight metric by shedding load.

摘要： Complete and partial object publication using, for example, MQTT or other protocol is described. In some embodiments, an emphasis is placed on keeping the amount of state information that the broker must maintain to a minimum, as well as allowing idempotent operations over objects in order to keep the object view between the subscribers consistent. Embodiments are described in which only the parts of an object have changed are transferred to the subscribers who subscribe to that object.

摘要： The present disclosure relates to a method and apparatus for managing connectivity between a cellular network 15 (in which device communicate via long-range wireless technology) and devices in one or more multi-hop capillary networks 16 (in which devices communicate via short-range wireless technology). One or more gateways 24 connect the one or more multi-hop capillary networks 16 to the cellular network 15 and communicates via short-range and long-range wireless technology. A management node 28 determines a topology of the capillary network(s) 16 based on received reachability information. The topology indicates which devices are within communication range of other devices and gateways in the capillary network 16. The management node 28 makes determinations based on the topology and transmits notifications to a first device 26B within communication range of the one or more gateways 24 and to a second device 26A not within communication range of any gateway.

摘要： A first communication device transmits, to a second communication device, a first indication indicating a configuration enabling the first communication device to receive a partial modification of resources. The first communication device receives, from the second communication device, a second indication indicating a partial update, in time, associated with a resource and a value of a part of the resource. The first communication device further maintains an internal value of the part of the resource based on the second indication.

摘要： A method in a network node of a communication network configured to manage command messages from at least one Machine Type Communication, MTC, device manager intended for an MTC device, comprises receiving command messages from the at least one MTC device manager, step (201). One or more command messages are merged into an MTC device message that comprises at least one command message, step (203). Originator information is associated with each command message in the MTC device message, step (205). The MTC device message is sent to an MTC device. The network node may further perform the steps of receiving an MTC device message from an MTC device, the MTC device message comprising at least one response message, step (301). The network node determines from receiver information contained in the MTC device message which one or more MTC device managers are to receive each of the at least one response message, step (303), and sends the at least one response message to each of the determined MTC device managers, step (305).
