The described technology is generally directed towards network slicing for private cellular networks (PCNs). Network slicing can be leveraged as described herein to meet security requirements and/or other policies applicable to PCNs. Network slices implemented according to this disclosure can comprise a private network slice, a public network slice, and a public safety network slice. User equipment can be provisioned with slice identifiers for the network slices, and applications at the user equipment can specify an appropriate slice identifier for their network communications. Network equipment can be configured to route application traffic to a specified slice and to allocate network resources according to the specified slice, as well as to implement security and other policies according to the specified slice.

Concepts and technologies disclosed herein are directed to virtual zones for Open Systems Interconnection ('OSI') communication model layers 4-7 services in a cloud computing system. According to one aspect of the concepts and technologies disclosed herein, a cloud computing system can include a hardware resource and a virtual zone. The virtual zone can include a virtual network function ('VNF') that is executable by the hardware resource. The VNF can support a service that operates within one of layers 4-7 of the OSI communication model. A computing system can detect new subscribers to the service within the virtual zone. The computing system also can determine that a capacity constraint exists within the virtual zone as a result of the new subscribers. The computing system also can home the new subscribers to the further virtual zone so that the further VNF can provide the service to the new subscribers.

Virtual zones for open systems interconnection layer 4 through layer 7 services in a cloud computing system

According to one aspect disclosed herein, a service centric virtual network function architecture can be used for development and deployment of services in a cloud computing system. The cloud computing system can include a plurality of compute resources and a plurality of memory resources. A portion of the plurality of memory resources can include virtual machine monitor instructions. The virtual machine monitor instructions can be executed by a first portion of the plurality of compute resources to perform operations. In particular, the virtual machine monitor instructions can be executed by the first portion of the plurality of compute resources to instantiate a virtual network function to be executed by a second portion of the plurality of compute resources. The virtual network function can include at least a portion of a decomposition of a physical network function that supports at least a portion of a telecommunications service.

Concepts and technologies disclosed herein are directed to a service compiler component and service controller for Open Systems Interconnection ('OSI') communication model layer 4 through layer 7 services in a cloud computing system. According to one aspect of the concepts and technologies disclosed herein, the service compiler component can receive compiler data associated with a new service. The service compiler component also can analyze the compiler data at least to determine at least one virtual network function ('VNF') to be used to instantiate the new service. The service compiler also can generate a template for the new service.

According to one aspect of the concepts and technologies disclosed herein, a cloud computing system can include a hardware resource and a Network Platform as a Service ('NPaaS') layer. The NPaaS layer can expose a cloud service for use by a service that operates within at least one of layer 4 through layer 7 of the Open Systems Interconnection ('OSI') communication model. The cloud service can include a database service, an application container service, a resource broker service, a load balancer service, a domain name system (&#x201c;DNS&#x201d;) service, a state persistence service, a probe service, or a combination thereof. The NPaaS also can receive a request for the cloud service, and in response to the request, can provide the cloud service.

The present invention is directed to a method and apparatus for learning call routing information in a communication system. A switching architecture is presented. The switch may be implemented in a centralized architecture or a distributed architecture. In addition, the switch may be implemented in a variety of networks such as a circuit-switched network or a packet-switched network. The switch includes a policy server and a self-learning application server. The policy server includes routing information for routing calls across the switch. The routes for incoming and outgoing calls are analyzed as they pass through the switch. The self-learning application server uses artificial intelligence techniques and caching algorithms to learn new more-efficient routing paths or initial routing paths based on the incoming and outgoing calls. The self-learning application server then updates the policy server with the new learned routes.

Session Initiation Protocol (SIP) signaling messages, such as a SIP INVITE message and/or a SIP Redirect message, which are adapted for communicating signaling information between a plurality of network elements located on a multi-media services provider system to set-up a call between at least a first communication device and at least a second communication device of a plurality of communication devices. The SIP INVITE message includes a plurality of address and/or routing information located in a request-URI portion. The SIP Redirect message includes a plurality of address and/or routing information located in a contact header portion.

A method and apparatus for providing a communications service feature to a party communicating through a network. It is first determined if the party making the communication is a subscriber based on an identifier associated with the party and a local database containing a subset of subscriber identifiers. It is then verified that the identifier associated with the party is in the subset of identifiers that would be included in this local database. For those identifiers that are not in the local database and that are not in the subset of identifiers that would be included in the local database, a global database containing all subscriber identifiers is queried to determine if the party is a subscriber. It can also be verified that the network provider knows the identifier of the party making the communication and that the provider is able to provide the communications service feature for the particular communication. If the party is a subscriber and the above conditions are met, the communications service feature is provided.

To facilitate routing changes, a telecommunications network () includes a centralized network routing database () queried by each ingress switch upon receipt of a call by a calling subscriber (). In response to the query, the network routing database returns to the querying switch the identity on the next (downstream) switch in the routing path. The querying switch then translates the switch identity to establish the link to that next switch. Because each querying switch makes the necessary translation of the next switch identity to make the link to the next switch, the centralized network database need not concern itself with the particular characteristics of the switch. To make global routing changes, only the network routing database need be updated, not each individual switch.

Method and apparatus for providing telecommunications services

Virtual dedicated access of telecommunication subscribers (12, 14 and 16) to an inter-exchange carrier (IXC) (20) is provided by way of an intelligent local End Office switch (180) that routes calls either to the IXC or to a local End Office switch (18). The intelligent local End Office switch (180) advantageously serves to perform inter-exchange processing of calls, as required, for calls that originate with, or terminate at, a customer rather than automatically route calls to the IXC for such inter-exchange processing, as was previously required.
