Security key generation for simultaneous multiple cell connections for mobile device

摘要

A first security context is established between a given user computing device and a first network computing device associated with a first network cell of a communications network to enable a secure data connection between the given user computing device and the first network computing device. A second security context is established between the given user computing device and a second network computing device associated with a second network cell of the communications network to enable a secure data connection between the given user computing device and the second network computing device simultaneous with the secure data connection between the given user computing device and the first network computing device. Establishment of the second security context includes the first network computing device sending the given user computing device a simultaneous secure data connection parameter useable by the given user computing device to establish the second security context with the second network computing device.

主权项

1. A method, comprising:
establishing a first security context between a given user computing device and a first network computing device associated with a first network cell of a communications network to enable a secure data connection between the given user computing device and the first network computing device; and establishing at least a second security context between the given user computing device and at least a second network computing device associated with at least a second network cell of the communications network to enable a secure data connection between the given user computing device and the second network computing device simultaneous with the secure data connection between the given user computing device and the first network computing device, wherein establishment of the second security context comprises the first network computing device sending the given user computing device a simultaneous secure data connection parameter useable by the given user computing device to establish the second security context with the second network computing device; wherein the simultaneous secure data connection parameter comprises a counter that is changed to a unique predetermined value for the second network cell and each other additional network cell to enable the given user computing device to establish unique security contexts for simultaneous secure data connections with the second network cell and each other additional network cell.
