Disclosed are apparatus and a method for managing communication for context based header compression. The apparatus for managing communications comprises: a context selection unit for selecting a context array which is a continuous array of headers and is to be compressed into one unit among a continuous array of headers included in a packet transmitted over a network; and a context table management unit for generating a context table in which the selected context array is written, and transmitting the context table to a communication device communicating over the network. According to the present invention, multiple headers included in a packet transmitted in a low-power wireless private network can be efficiently compressed, and compression can be performed by considering a packet header format used often. Also, when headers are compressed from a front header, the existing header compression problem that headers which are positioned after the headers other than seven types of headers capable of being compressed by NHC cannot be compressed although the headers are compressible can be solved by indicating the context information of headers being compressed.
