A method for bundling network functions as a single microservice in a cloud environment. A service deployment manager may acquire subscriber location information associated with a subscriber or a subscriber profile associated with the subscriber. Moreover, the service deployment manager may utilize the subscriber location information or the subscriber profile to select a cloud location. For example, the cloud location may be based on load, geographical proximity, service profile, etc.

Systems and methods to deploy cloud-native microservices for communication services on scale

When a virtualized service platform encounters a catastrophic fault, an orchestrator may instantiate new virtual machines instances to deploy additional capacity in other cloud locations to handle failover storms. After the network fault is fixed and service returns to normal condition, these additional VM instances may be removed from the platform and cloud resources may be released. The system may minimize the resource over-provisioning and may continue to support geographical redundancy or dynamic scaling in a large-scale service network.

Geographical redundancy and dynamic scaling for virtual network functions

A method for vNF chaining management includes receiving virtualized network function (vNF) information from a chaining client associated with a particular vNF. A service chaining catalog is updated based on the vNF information and chaining information is transmitted to peering vNFs of the particular vNF. The vNF information can indicate instantiation of a vNF and identify peering vNFs. Updates received from vNFs can be used to update the chaining catalog. Updated vNF information can then be sent to peering vNFs of the vNF which sent the update.

Method and apparatus for virtualized network function chaining management

A system may assist in moving a communication session in a stable state from a virtual network function serving that communication session to another virtual network function at that same site or another site, such as another cloud data center.

Call processing continuity within a cloud network

Concepts and technologies are disclosed herein for message flow management for virtual networks. A processor can identify a target virtual network function instance that is to be taken offline. The processor can change a status associated with the target virtual network function instance to indicate it being taken offline. The processor can start a graceful shutdown timer to trigger shutdown of the target virtual network function instance. The processor can identify external interfaces and a peer network function that identifies the target virtual network function instance as a next hop. The processor can obtain, for the target virtual network function instance and the peer network function instance, a snapshot that identifies configuration data for the target virtual network function instance and the peer network function instance and can generate a command to trigger a shutdown of the target virtual network function instance.

Message flow management for virtual networks

Aspects of the subject disclosure may include, for example, a system that detects a request to reattach to a communication network to update a registration between a wireless communication system and the communication network while the wireless communication system is connected to a session border controller of the communication network. The system delays a release of bearer communications with the communication network responsive to the request to reattach to the communication network not being urgent. Other embodiments are disclosed.

Updating connectivity with a communication network and methods thereof

Methods and apparatus to provide data network services to a non-registering endpoint are disclosed herein. A disclosed method includes, transmitting, by executing an instruction with a processor, information identifying the non-registering endpoint and a first list identifying a plurality of proxy-call session control functions to a plurality of serving-call session control functions, the plurality of proxy-call session control functions being statically assigned to process calls to the non-registering endpoint when selected by any of the plurality of serving-call session control functions. In the disclosed example method, the non-registering endpoint is unable to register with any data network. The first list can be provided to the plurality of serving-call session control functions in response to an event. Methods also include providing the data network service to the non-registering endpoint via one of the plurality of serving-call session control functions and a selected one of the plurality of proxy-call session control functions.

Methods and apparatus for providing network based services to non-registering endpoints

Many of the current IMS standards and enriched services were originally designed for the individual subscribers that are serviced by the wireless network. However, the IMS standards do not fully address the problem of providing the IMS enriched services and features to business PBX customers or wholesale customers that do not directly register to the IMS network. The present invention discloses a method for providing IMS enriched services and features to business PBX customers or wholesale customers through the use of a static provisioning and registration method.

Method and apparatus for providing network based services to non-registering endpoints

Aspects of the subject disclosure may include, for example, a communication device that receives a request to update a registration between the communication device and a communication network without causing the communication device to cycle power or reset. The communication device can postpone a process for releasing bearer communications with the communication network responsive to determining that the request to update registration between the communication device and the communication network can be delayed. Other embodiments are disclosed.

A method and apparatus for providing subscriber load distribution in networks are disclosed. For example, the method receives capacity data and user equipment (UE) resource consumption data from a plurality of devices that process call control signaling messages within the communication network. The method receives a first request from one of the plurality of devices to re-register one or more selected user equipment, and selects at least one available device from the plurality of devices. The method then re-registers the one or more selected user equipment on the at least one available device.
