Method of privatizing mobile communications using dynamic IMSI and MSISDN

摘要

A method of privatizing mobile communications using a dynamic International Mobile Subscriber Identity (IMSI) and Mobile Station International Subscriber Director Number (MSISDN). A first privacy token having an associated IMSI and MSISDN is provided to a User Equipment (UE). The first privacy token has a predefined validity period. The IMSI and MSISDN assigned to the privacy token are shared with a plurality of Mobile Network Operators (MNOs), while the International Mobile Equipment Identity (IMEI) of the UE remains concealed. A communications session for the UE can be established based on the first privacy token during the validity period thereof. Upon expiration of the validity period, the first privacy token and the associated IMSI and MSISDN are released to the token database, and their association with one another is deleted. The UE is then provided with a second privacy token having a different associated IMSI and MSISDN.
