Claim
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.
2. The method of claim 1, wherein the simultaneous secure data connection parameter comprises a counter function that is configured to monotonically increase or monotonically decrease for each simultaneous data connection.
3. The method of claim 2, wherein the counter function, when configured to monotonically increase, equals an initial value incremented by one for the simultaneously- connected second network computing device, and is further incremented each time another network computing device is enabled by the first network computing device to establish another security context with the given user computing device.
4. The method of claim 3, wherein the counter function is controlled by the first network computing device to denote the instance of simultaneous connection with another network computing device for the given user computing device.
5. The method of claim 1, wherein establishment of the second security context further comprises computing a security key for the second security context using of a key derivation function based on a security key established for the first security context and the simultaneous secure data connection parameter.
6. An apparatus comprising one or more memories and one or more processors coupled to the one or more memories, and configured to perform the steps of the method of claim1.
7. A method, comprising:', 'given a first security context established between a first network computing device associated with a first network cell of a communications network and a given user computing device to form a secure data connection between the given user computing device and the first network computing device;', 'determining at the first computing device to initiate an offload operation;', 'causing establishment of 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 form 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 the second security context is at least partially based on a simultaneous secure data connection parameter controlled by the first network computing device.
8. An apparatus comprising a memory and a processor coupled to the memory, and configured to perform the steps of the method of claim 7.
9. A method, comprising:', 'given a first security context established between a first network computing device associated with a first network cell of a communications network and a given user computing device to form a secure data connection between the given user computing device and the
first network computing device, and given a determination at the first computing device to initiate an offload operation;', 'the given user computing device establishing at least a second security context with at least a second network computing device associated with at least a second network cell of the communications network to form 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 the second security context is at least partially based on a simultaneous secure data connection parameter controlled by the first network computing device and sent to the given user computing device
10. An apparatus comprising a memory and a processor coupled to the memory, and configured to perform the steps of the method of claim 9.']
