Validity information conditions for a protocol data unit session for background data transfer
Apparatuses, methods, and systems are disclosed for using validity information conditions for a protocol data unit session for background data transfer. One method for using validity information conditions for a protocol data unit session for background data transfer includes a device determining validity information for the protocol data unit session for the background data transfer. The device initiates release of the protocol data unit session if a condition of the validity information is not satisfied.
1. A method of a network function serving a user equipment, the method comprising:
determining, by the network function, validity information for a protocol data unit session for background data transfer, wherein the validity information comprises a time interval, a time window, location information, a volume of data, or some combination thereof, and wherein determining the validity information comprises receiving the validity information to a second network function as a policy rule;
establishing the protocol data unit session; and
after establishing the protocol data unit session, initiating, by the network function, release of the protocol data unit session in response to a condition of the validity information not being satisfied.
2. The method of claim 1 , further comprising receiving, from a network entity, the validity information, wherein the network entity comprises a policy control function.
3. The method of claim 1 , wherein the validity information comprises one or more validity conditions, one or more validity rules, or a combination thereof.
4. The method of claim 1 , wherein the second network function comprises a session management function.
5. The method of claim 1 , wherein a user equipment is configured with the validity information.
6. The method of claim 1 , wherein the release of the protocol data unit session is initiated in response to a user equipment moving outside of a valid area.
7. The method of claim 1 , wherein the release of the protocol data unit session is initiated in response to a time window expiring.
8. An apparatus comprising a network function serving a user equipment, the apparatus further comprising:
a receiver; and
a processor that:
determines, by the network function, validity information for a protocol data unit session for background data transfer, wherein the validity information comprises a time interval, a time window, location information, a volume of data, or some combination thereof, and wherein determining the validity information comprises the receiver receiving the validity information to a second network function as a policy rule;
establishes the protocol data unit session; and
after establishing the protocol data unit session, initiates, by the network function, release of the protocol data unit session in response to a condition of the validity information not being satisfied.
9. The apparatus of claim 8 , further comprising a receiver that receives, from a network entity, the validity information, wherein the network entity comprises a policy control function.
10. The apparatus of claim 8 , wherein the validity information comprises one or more validity conditions, one or more validity rules, or a combination thereof.
11. The apparatus of claim 8 , wherein the second network function comprises a session management function.
12. The apparatus of claim 8 , wherein a user equipment is configured with the validity information.
13. The apparatus of claim 8 , wherein the release of the protocol data unit session is initiated in response to a user equipment moving outside of a valid area.
14. The apparatus of claim 8 , wherein the release of the protocol data unit session is initiated in response to a time window expiring.
