Abstract: Aspects of the subject disclosure may include, for example, facilitating a registration process such as by storing service information associated with a group of providers, which can include location information associated with the equipment, Data Network Name (DNN), Public Land Mobile Network (PLMN), and/or Single-Network Slice Selection Assistance Information (S-NSSAI). A service process can include wirelessly receiving a service request from a communication device, where the service request identifies a particular service and includes location information of the communication device; selecting a provider from among the group of providers according to the service request and the stored service information; and wirelessly providing provider information for the provider to the communication device that includes the corresponding DNN and the S-NSSAI of the provider, whereby the communication device can then attach to the corresponding equipment of the provider and obtain the particular service.

Abstract: Aspects of the subject disclosure may include, for example, identifying a set of network functions operative on a core network of a mobile communications system instantiated on a cloud network, identifying functional dependencies among respective network functions of the set of network functions, defining a sequence by which the set of network functions should be made unavailable prior to a maintenance event, wherein the defining the sequence is based on the functional dependencies, and deactivating respective network functions of the set of network functions according to the sequence. Other embodiments are disclosed.

Abstract: A system includes a plurality of cache servers and a domain name server. Each of the cache servers is configured to respond to a content request. The plurality of cache servers is divided into a plurality of subsets and configured to respond to an anycast address for each subset to which the cache server belongs. The domain name server is configured to receive a request from a requestor for a cache server address, identify an anycast address for a largest available subset, and provide the anycast address of the largest available subset to the requestor.
