Method for establishing a communication connection of a communication terminal via a communication network

Abstract

The invention relates to a method (400) for establishing a communication connection of a communication terminal (301) via a communication network (303) having a network with a first subnetwork (307) and a second subnetwork (307) A plurality of subnetworks (307, 311) of a network (311), wherein a first identity entity (309) is placed in the first subnetwork (307) and a second identity entity (313) is placed in the second subnetwork network (311) to identify the communication device (301), wherein a subnet code is assigned to each subnet (307, 311) of the communication network (303), wherein a management entity (319) is set in the communication network ( 303), the management entity manages the assignment (321) of the communication terminal (301) to one of the two subnetworks (307, 311), and wherein the method (400) comprises the steps of: via the first subnetwork (307) a first identification entity (309) to receive (401) the identification (302) of the communication terminal (301), wherein the identification (302) identifies the communication terminal (301); by means of the first identification entity ( 309) identify (402) the communication terminal (301) based on the identification (302) of the communication terminal (301); Assigning (321) to assign (403) the subnet to the communication terminal (301); and if the subnet code (306) of the identification (302) assigned to the communication terminal (301) corresponds to the first subnet (307 ), then establish (404) the communication connection (308) of the communication terminal (301) via the first subnet (307); or if assigned to the subnet of the transmitted identification (302) If the code (306) is different from the subnet code (312) of the first subnet (307), the communication connection (310) of the communication terminal (301) is established via the second subnet (311).

Description

technical field [0001] The present invention relates to communication setup in communication networks with multiple subnets, in particular in 5G communication networks with multiple slices. Background technique [0002] The fifth generation of mobile technology (5G) involves the requirements and technical challenges of future communication networks from approximately 2020 and beyond. The needs of a fully mobile and networked society characterized by enormous data traffic growth and multiple layers of interconnectedness are thereby addressed. [0003] New radio interfaces are required in 5G in order to meet the requirements imposed on the use of higher frequencies, e.g. Require. In this context, 5G is considered an end-to-end system that includes all network aspects for a highly converged design. 5G will make full use of current access mechanisms and their possible further improvements, including current fixed network access technologies for many other access technologies ...
