METHOD AND DEVICE TO PREPARE TRANSFER OF CONNECTION BETWEEN COMMUNICATION SYSTEM BASED ON IP (LTE/SAE) AND COMMUNICATION SYSTEM BASED ON PDP CONTEXT (UMTS/GPRS) Russian patent published in 2011 - IPC H04W36/14 

FIELD: information technologies.

SUBSTANCE: according to method and device for provision of systems interaction in realisation of wireless connection, the client-server application on the basis of IP preserves the appropriate set of contexts PDP, when a mobile station is connected via the system on the basis of IP, such as LTE/SAE. Client of application is permanently located in a mobile station, and server is permanently located in the network in a common point (115) of connection between the system (103) on the basis of IP and the system (111) on the basis of PDP context. PDP contexts are maintained in updated, but frozen condition, until transfer of service is realised for mobile station from the system (111) on the basis of IP.

EFFECT: invention facilitates interaction between communication networks.
