WIPO Patent Application WO/2018/010617
Kind Code:
A1
Abstract:
A method and apparatus for storing and using context information in a wireless communication network are provided. Context information is encrypted and transmitted to a mobile device for storage. A cryptographic key usable for decrypting the context information is stored at a radio access node or other node in the network and an indication of the key and the location of the key is stored at the mobile device. The mobile device transmits a message which includes the key identifier and location and the encrypted context information. The message may further include application data and the encrypted context information may include an indication of a further key for encrypting and decrypting application data in transmissions between the mobile device and the communications network.
