Statement of the problem. The Publication/Subscription is perspective architecture of the intermediate software (ON), supporting mobility, a reorganisation and its evolution. Existing intermediate ON Publications/Subscriptions it has been optimised for stationary systems where users, and also base structure of system, were fixed in space. In work the question on is considered, whether it is possible to expand existing intermediate ON Publications/Subscriptions for support of appendices mobile and independent of a site. expansion of the existing intermediate software of the Publication/Subscription, supposing moving of clients so that existing appendices could be used in mobile environments.

Aim of the work – extend existing Publishing/Subscription middleware to allow for the movement of clients so that existing applications can be used in mobile environments.

Results. in given article the approach to support of mobility in the existing intermediate software of the report of the Publication/subscription is presented. Problems of mobility from the point of view of a paradigm based on events have been analysed, and two separate aspects – physical and logic mobility are defined. While physical mobility, is connected with concept of a reshaping of the client for different brokers and can be realised is transparent, logic mobility which concerns the certain form of awareness on a site of the client, and offering to the client the control of delivery of notices in the form of the filters depending on its site.

The practical significance. The basic questions which appear at addition of support of mobility in an infrastructure the Publications/Subscriptions are analyzed and discussed. Two orthogonal forms of mobility (physical and logic mobility) are defined and requirements of the system supporting both types of mobility are discussed.
