Abstract
Apparatuses, methods, and systems are disclosed for determining mobile network policy freshness. One method (700) includes accessing (702) a first policy associated with a first mobile network, a first policy identifier, and a freshness parameter. The method (700) includes determining (704), based on the freshness parameter, whether the first policy is fresh. The method (700) includes transmitting (706) a registration message to a second mobile network. The registration message includes the first policy identifier in response to determining that the first policy is not fresh.

Claim
1. A method comprising:
accessing a first policy associated with a first mobile network and a first policy identifier, wherein the first policy identifier indicates whether the first policy is fresh; determining whether the first policy is fresh based on the first policy identifier; and transmitting a registration message to a second mobile network, wherein the registration message comprises the first policy identifier in response to determining that the first policy is not fresh.
2. The method of claim 1, wherein the first policy identifier indicates a version of the first policy.
3. (canceled)
4. The method of claim 1, further comprising determining to register with the second mobile network, wherein transmitting the registration message to the second mobile network is performed in response to determining to register with the second mobile network.
5. The method of claim 4, wherein registering with the second mobile network comprises initially registering with the second mobile network.
6. The method of claim 4, wherein registering with the second mobile network comprises registering with the second mobile network to update a location of a remote unit.
7. The method of claim 1, further comprising determining that there is no policy associated with the second mobile network and, in response to determining that there is no policy, transmitting the registration message without a policy identifier.
8. The method of claim 1, further comprising determining whether there is a second policy corresponding to the second mobile network and, in response to determining that there is no second policy and that the first policy is fresh, transmitting the registration message without a policy identifier.
9. The method of claim 1, wherein the first mobile network is the same as the second mobile network.
10. The method of claim 1, wherein the first mobile network is different from the second mobile network.
11. An apparatus comprising:
a processor that:
accesses a first policy associated with a first mobile network and a first policy identifier, wherein the first policy identifier indicates whether the first policy is fresh; and
determines whether the first policy is fresh based on the first policy identifier; and
a transmitter that transmits a registration message to a second mobile network, wherein the registration message comprises the first policy identifier in response to determining that the first policy is not fresh.
12. The apparatus of claim 11, further comprising a receiver that receives a message following successful registration, wherein the message comprises a new policy.
13. The apparatus of claim 11, further comprising a receiver that receives a message following successful registration, wherein the message comprises a new freshness parameter for the first policy.
14. The apparatus of claim 11, wherein the processor determines whether the apparatus is roaming.
15. The apparatus of claim 14, further comprising a receiver that receives a message following successful registration, wherein the message comprises a new policy from the first mobile network.
16. The apparatus of claim 11, wherein the processor, in response to determining that the policy is not fresh, continues to use the policy.
17. A method comprising:
receiving a first message from a remote unit, the first message comprising a first policy identifier associated with a first policy; determining, based on the first policy identifier, whether the first policy is to be updated; and transmitting a second message to the remote unit, the second message comprising a second policy and a second policy identifier, wherein the second message is transmitted in response to determining that the first policy is to be updated, and the second policy identifier indicates whether the second policy is fresh.
18. The method of claim 17, wherein determining, based on the first policy identifier, whether the policy is to be updated, comprises transmitting the first policy identifier to a home mobile network and receiving information from the home mobile network that indicates whether the policy is to be updated.
19. The method of claim 18, wherein the information comprises the second policy with the freshness parameter associated with the second policy.
20. The method of claim 17, wherein determining, based on the first policy identifier, whether the first policy is to be updated, comprises comparing the first policy identifier of the first policy to the second policy identifier.
21. An apparatus comprising:
a receiver that receives a first message from a remote unit, the first message comprising a first policy identifier associated with a first policy; a processor that determines, based on the first policy identifier, whether the first policy is to be updated; and a transmitter that transmits a second message to the remote unit, the second message comprising a second policy and a second policy identifier, wherein the second message is transmitted in response to determining that the first policy is to be updated, and the second policy identifier indicates whether the second policy is fresh.
22. (canceled)
