Abstract
A user equipment establishes an elevated priority data connection and one or more non-elevated priority data connections. The elevated priority data connection may be an emergency public data network (PDN) connection. The user equipment may determine that one or more deactivation criteria for the emergency PDN connection is satisfied while the emergency PDN connection and at least one non-emergency PDN connection of the user equipment are active. Deactivation criteria may include expiration of a Periodic Tracking Area Update timer. In response, the user equipment may locally deactivate the emergency PDN connection and send a deactivation indication to the operator network.
Claims20
A method comprising:
- in a user equipment:
- establishing a non-elevated priority data connection;
- establishing an elevated priority data connection;
- identifying a deactivation criterion for deactivating the elevated priority data connection;
- determining that the deactivation criterion is satisfied;
- and
- when the elevated and non-elevated priority data connections are active upon determining the deactivation criterion is satisfied:
- deactivating the elevated priority data connection.
A device comprising:
- a memory storing a deactivation criterion;
- and
- system logic in communication with the memory, the system logic configured to:
- read the deactivation criterion from the memory;
- establish a non-elevated priority data connection with the operator network;
- establish an elevated priority data connection with an operator network;
- determine that the deactivation criterion is satisfied while the elevated and non-elevated priority data connections are active, and in response:
- deactivate the elevate priority data connection while maintaining the non-elevated priority data connection.
A device comprising:
- a communication interface;
- and
- system logic in communication with the communication interface, the system logic configured to:
- obtain a periodic timer value from an operator network through the communication interface;
- establish an emergency public data network (PDN) connection with the operator network through the communication interface;
- maintain a timer based on the period timer value obtained from the operator network;
- determine that the emergency PDN connection and at least one non-emergency PDN connection are active upon expiration of the timer, and in response:
- locally deactivate the emergency PDN connection;
- and
- send an deactivation indication to the operator network that the emergency PDN has been locally deactivated.
