User service prediction in a communication network

A network node for a communication network, the network node comprising:

• processor circuitry;
• and
• a storage unit storing instructions that, when executed by the processor circuitry, cause the network node to:
• obtain information about which services, of a plurality of services, have historically been used in which historic time slots in the communication network;
• analyze the obtained information;
• based on analyzing the obtained information, determining that using a first service in one or more of the historic time slots correlates with using a second service in said one or more of the historic time slots, wherein the first service belongs to a first group of services, the second service belongs to a second group of services, and the second service is a representative service of the second group of services;
• predict whether the first service will be used by a user in a future time slot;
• predict, based on that the first service has been predicted to be used in the future time slot, whether the second service will be used by the user in the future time slot;
• determine that the second service belongs to the second group of services;
• predict, based on that (i) the second service is a representative service, (ii) the second service belongs to the second group of services, (iii) a third service also belongs to the second group of services, (iv) the third service is a represented service, and (v) the second service has been predicted to be used by the user in the future time slot, whether the third service will be used by the user in the future time slot;
• and
• adjust at least one parameter of the communication network based on the prediction of whether any one or any combination of the first service, the second service, and the third service will be used by the user in the future time slot.

A computer program product comprising a non-transitory computer readable medium storing a computer program, the computer program comprising computer program code which is able to, when run on processor circuitry of a network node, cause the network node to:

• obtain information about which services, of a plurality of services, have historically been used in which historic time slots in a communication network;
• analyze the obtained information;
• based on analyzing the obtained information, determining that using a first service in one or more of the historic time slots correlates with using a second service in said one or more of the historic time slots, wherein the first service belongs to a first group of services, the second service belongs to a second group of services, and the second service is a representative service of the second group of services;
• predict whether the first service will be used by a user in a future time slot;
• predict, based on that the first service has been predicted to be used in the future time slot, whether the second service will be used by the user in the future time slot;
• determine that the second service belongs to the second group of services;
• predict, based on that (i) the second service is a representative service, (ii) the second service belongs to the second group of services, (iii) a third service also belongs to the second group of services, (iv) the third service is a represented service, and (v) the second service has been predicted to be used by the user in the future time slot, whether the third service will be used by the user in the future time slot;
• and
• adjust at least one parameter of the communication network based on the prediction of whether any one or any combination of the first service, the second service, and the third service will be used by the user in the future time slot.
