Abstract: Embodiments include methods for decompression of headers of received Internet Protocol (IP) packets, such as by a device. Such methods include receiving a single transmission unit that includes a bitmap comprising a plurality of bits, and an aggregation of a first IP packet and a reference IP packet. Each bit in the bitmap indicates whether a corresponding header information element, of a header of the first IP packet, is redundant or non-redundant with respect to a corresponding header information element of a header of the reference IP packet. Such methods include reconstructing the header of the first IP packet based on the header of the reference IP packet and on the bitmap, and decompressing the header of the first IP packet. Other embodiments include devices configured to perform operations corresponding to such methods, and computer-readable media comprising computer-executable instructions that embody such methods.

Abstract: A method performed by a machine-to-machine, M2M, server for managing communication with a M2M device is disclosed. The method comprising configuring the M2M device with a finite number of predetermined states and predetermined transitions for moving the M2M device into one of its predetermined states, and sending a message to the M2M device for executing at least one of the predetermined transitions.

Abstract: A method (30) performed in a device (4a, 4b) for compression of headers of Internet Protocol, IP, packets, is described. The method (30) comprises aggregating (31) a first IP packet (13; 25) and a reference IP packet (12; 24) into a single transmission unit (16); identifying (32) header information elements in the first IP packet (13; 25) to be redundant or non-redundant; indicating (33) the header information elements to be redundant or non-redundant by a bitmap; and compressing (34) the header of the first IP packet (13; 25) according to the bitmap. A corresponding method for decompressing is also provided, and devices, computer programs and computer program products.
