Selecting a network node based on precedence of network policies

A method for network node selection of a user equipment (UE), the method comprising:

• receiving, from a home network, a message comprising a home network policy associated with a network node selection;
• determining, by the UE, whether the home network policy has a precedence over a visited network policy of a visited network based on an indication of a precedence between the home network policy and the visited network policy in the message, wherein the indication of the precedence comprises an access node list, wherein the determining further comprises:
• comparing the visited network to entries in the access node list,
• determining the home network policy has the precedence if the visited network does not match any of the entries in the access node list, and
• determining the visited network policy has the precedence if the visited network matches any of the entries in the access node list;
• and
• selecting a network node based on the home network policy in response to the determining that the home network policy has the precedence over the visited network policy.

An apparatus, the apparatus being a user equipment (UE), comprising:

• at least one processor configured to:
• receive, from a home network, a message comprising a home network policy associated with a network node selection;
• determine, by the UE, whether the home network policy has a precedence over a policy of a visited network based on an indication of a precedence between the home network policy and the visited network policy in the message;
• determine that the visited network policy has the precedence based on receiving no indication of the precedence in the message;
• select a network node based on the home network policy in response to the determining that the home network policy has the precedence over the visited network policy;
• and
• select the network node based on the visited network policy in response to determining the visited network policy has the precedence over the home network policy;
• and
• a memory coupled to the at least one processor for storing data.

An apparatus, the apparatus being a user equipment (UE), comprising:

• at least one processor configured to:
• receive, from a home network, a message comprising a home network policy associated with a network node selection;
• determine, by the UE, whether the home network policy has a precedence over a policy of a visited network based on an indication of a precedence between the home network policy and the visited network policy in the message;
• wherein the indication of the precedence comprises an access node list, and the at least one processor is further configured for performing the determining at least in part by comparing the visited network to entries in the access node list, determining the home network policy has the precedence if the visited network is not matched to any of the entries in the access node list, and determining that the visited network policy has the precedence if the visited network is matched to any of the entries in the access node list;
• and
• select a network node based on the home network policy in response to the determining that the home network policy has the precedence over the visited network policy;
• and
• a memory coupled to the at least one processor for storing data.

An apparatus, the apparatus being a user equipment (UE), comprising:

• means for receiving, from a home network, a message comprising a home network policy associated with a network node selection;
• means for determining whether the home network policy has a precedence over a policy of a visited network based on an indication of a precedence between the home network policy and the visited network policy in the message;
• means for determining that the visited network policy has the precedence based on receiving no indication of the precedence in the message;
• means for selecting the network node based on the home network policy in response to the determining that the home network policy has the precedence over the visited network policy;
• means for selecting the network node based on the visited network policy, in response to determining the visited network policy has the precedence over the home network policy.

• means for selecting the network node based on the home network policy in response to the determining that the home network policy has the precedence over the visited network policy.

A non-transitory computer readable medium comprising code for causing at least one processor to:

• receive, from a home network, a message comprising a policy associated with a network node selection;
• determine, by a user equipment (UE), whether the home network policy has a precedence over a policy of a visited network based on an indication of a precedence between the home network policy and the visited network policy in the message;
• determine the visited network policy has the precedence based on receiving no indication of the precedence in the message;
• select a network node based on the home network policy in response to the determining that the home network policy has the precedence over the visited network policy;
• and
• select the network node based on the visited network policy in response to determining the visited network policy has the precedence over the home network policy.
