First node, second node, third node and methods performed thereby for handling roaming information
A method, performed by a first node is described, the method being for handling roaming information. The first node operates in a first communications network. The first node determines a set of network resources predicted to be required by a group of subscribers while roaming in a second communications network. The first node then initiates providing an indication of the determined set of resources to a second node in the second communications network. The second node receives the indication and determines whether or not an allocation of the set of resources meets a criterion. The second node then initiates performing an operation based on the determination. A third node determines data regarding a roaming behavior of the group of subscribers and provides information based on the determined data, to the first node.
1. A method, performed by a second node, for handling roaming information, the second node operating in a second communications network, the method comprising:
receiving, from a first node operating in a first communications network, a first indication of a set of network resources predicted to be required by a group of subscribers of the first communications network while roaming in the second communications network,
determining whether or not an allocation of the set of network resources for use by the group of subscribers meets an allocation criterion, and
initiating performing an operation based on a result of the determination, the operation being selected out of:
a) allocating the set of network resources for use by the group of subscribers with the proviso that the criterion is met, and
b) sending a second indication to the first node, with the proviso that the criterion is not met, the second indication indicating that the second node is to refrain from allocating the set of network resources.
2. The method according to claim 1 , wherein the first communications network is a home Fifth Generation, 5G, network, the second communications network is a visited 5G network, and the set of network resources predicted to be required is to instantiate a federated slice in the second communications network.
3. The method of claim 2 , wherein the third node is a fourth node, and wherein:
the data is the first historical data on the roaming pattern, and
the information is first information based on the first historical data.
4. The method of claim 2 , wherein the third node is a fifth node, wherein:
the data is the second historical data on a pattern of outgoing calls, and
the information is second information based on the second historical data.
5. The method of claim 2 , wherein the third node is a sixth node in the first communications network, and wherein:
the data is the current data on the users of the first communications network, and
the information is third information based on the current data.
6. The method of claim 2 , wherein the third node is a seventh node, and wherein:
the data is the first data from Uniform Locators visited by the group of subscribers, and
the information is fourth information based on the first data.
7. The method of claim 2 , wherein the third node is an eighth node, and wherein:
the data is the second data from Over the Top service providers used by the group of subscribers, and
the information is fifth information based on the second data.
8. The method of claim 2 , wherein the third node is a ninth node, and wherein:
the data is the third data on roaming plans activated by the group of subscribers, and
the information is sixth information based on the third data.
