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： 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： 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： 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： The present disclosure discloses a method (400) performed by a router connected to an IPv6 network and an IPv4 network. The method comprises receiving (S410), from an IPv4 compliant device connected to the IPv4 network, a request for an IPv6 network resource enabled by an IPv6 compliant device connected to the IPv6 network, and obtaining (S420) from a first resource directory an external IPv4 address and an external IPv4 port number corresponding to the IPv6 network resource. The first resource directory comprises a name, a local IPv6 address and a local IPv6 port for the IPv6 network resource, the external IPv4 address, and the external IPv4 port number. The method (400) further comprises creating (S430) an entry in a network address translation table for enabling communication between the IPv4 compliant device and the IPv6 network resource. The entry comprises the external IPv4 address, the external IPv4 port number, the local IPv6 address and the local IPv6 port number for the IPv6 network resource, and a local IPv4 address and a local IPv4 port for the IPv4 compliant device. The method further comprises transmitting (S440) the external IPv4 address and the external IPv4 port number to the IPv4 compliant device.

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.
