Also disclosed are a method in a user equipment device, a computer program product for carrying out such methods, a network node and a user equipment device.

Method for managing a user equipment device

A method in a node of a communication system for selecting a message box for a machine device. The communication system comprises one or more capillary networks and a wireless network, the one or more capillary networks comprising one or more machine devices and at least two capillary network gateways. The at least two capillary network gateways are capable of data exchange between the machine device and the wireless network. The method comprises establishing, for the machine device, a first probability reflecting the probability that the machine device changes capillary network gateway between two consecutive data transmission events performed by the machine device, and selecting, based on the first probability, a message box for use by the machine device. Further described are a corresponding node, computer programs and computer program products.

Method and node for selecting a message box

A node () in an information centric network (ICN) receives a first identifier associated with an information object. The node () causes creation of a virtual node () in the ICN, for holding a mapping between a second identifier and the first identifier. The second identifier is assigned to a copy of the information object stored in the ICN. The node () causes creation of the virtual node () such that the mapping is arranged to cease after a predetermined event. The virtual node () is created with the sole purpose of providing copies of the information object to a small number of requestors (), and possibly to just one requestor (). Ceasing the mapping after delivery of the one copy, or the few copies, of the information object prevents unauthorized retrieval of the information object.

Access control in an information centric network

A method performed by a first node in a communication network, the first node being a first end-point of signalling with a second node in the communication network, the second node being a second end-point in said signalling. The method comprises receiving signals from the second node, said received signals comprising instructions for the first node to perform a plurality of actions as well as an indication for in which order said actions should be performed. The method also comprises performing said actions in said order. The method also comprises sending signals to the second node, said sent signals comprising an acknowledgement that the plurality of actions have been performed.

Selection of capillary network gateway to a cellular network

A client node, a proxy node, and methods therein, as well as a protocol and a computer program for enabling interception of request messages in connection-less protocols. A primary request addressed to a server node is intercepted by a proxy node creating a secondary request based on said request and forwards this secondary request towards the server node. The proxy node receives a secondary response, being a response to the secondary request, creates a primary response based on the secondary response and forwards this primary response to the node from which the primary request was received. A response can thus be sent along the same path as a corresponding request was sent.

Proxy interception
