A method for optimizing group communication services, the method including determining a current location and an assigned home server for one or more devices associated with each of a plurality of group members, determining whether the one or more devices of the plurality of group members has moved to a visiting location, wherein the visiting location is a location outside of locations associated with the assigned home server based on the current location and assigned home server for the one or more devices, and assigning a group control application server associated with the visiting location to the to the one or more devices to serve as the assigned home server.

Group communication and service optimization system

Network and/or application resources can be dynamically instantiated based on service attributes and/or network capabilities. In one aspect, a customized and/or localized core slice can be selected that can deliver the requested service with target performance parameters. According to an aspect, dynamic selection, control, and/or management reporting can be provided for core network slices. Moreover, optimal core network slice selection can be performed to reduce network transport costs and efficiently deliver various services using an optimal core slice that matches a service profile being requested by an end user and/or device.

Next generation mobility core network controller for service delivery

A method for optimizing group communication services, the method comprising instantiating an adaptive homing tool as a virtual network function, the adaptive homing tool communicating with a centralized database in a multiple region telecommunications network; storing a user identification for plural group members in the database; when a service request is made by at least one group member that has moved outside of connectivity with a group home server, receiving group member location data for the plural group members in real time; assigning a group control application server to at least one group member when a group member initiates a service request; wherein the common service tool assigns the group application control server based on at least one of the priority data, group member location data, least network resources used, best path performance, shortest path performance, and quality of service.

A system that incorporates the subject disclosure may include, for example, receive a subscription from an application server where the subscription identifies a session event and/or sub-events occurring in a communication session for which the application server requests user location information, provide subscription information based on the subscription to core network nodes of the mobile communications network, receive user location information from the core network nodes responsive to a detection of a triggering event corresponding to the session event of the subscription, and provide the user location information to an IP multimedia subsystem network for delivery to the application server. Other embodiments are disclosed.

Method and system for managing user location information in a communication system

Utilizing a network service interface function within a machine-to-machine common service layer is presented herein. A method can comprise determining network configuration information for network devices coupled to a set of distributed remote devices; receiving a device request directed to a remote device of the set of distributed remote devices; determining, based on the network configuration information, a network interface for facilitating performance of the device request; and sending, via the network interface, command information corresponding to the device request directed to the remote device. In an example, in response to determining that a traffic load of a communication channel associated with the remote device satisfies a defined condition with respect to an increased loading of such channel, the method can comprise sending a message to request delay of the device request if the device request has been determined to be a non-priority request.

Network service interface for machine-to-machine applications

Aspects of the subject disclosure may include, for example, a network device that receives a failure message from a mobility management entity where the failure message indicates that a first connection request from an application server to an end user device failed based on the end user device being in an inactive mode, where the network device provides to the application server a target time for transmitting a second connection request to the end user device, and where the providing of the target time to the application server causes the application server to cease transmitting connection requests to the end user device until the target time. Other embodiments are disclosed.

Method and apparatus for managing failed connection requests for devices in an inactive mode

A downstream device in a network may monitor and collect data on its condition, including detecting overload conditions, and transmit such data to an upstream network device. The upstream network device may select a best downstream device for a particular traffic flow based on condition data received from downstream devices and transmit the traffic flow to the selected downstream device. A network management server may be configured to perform similar functions, instructing network devices on how to transport data through a network based on condition data received from such devices.

Long term evolution network dynamic overload management

System(s), device(s), and method(s) are provided to characterize a temporary identifier for user equipment (UE) in telecommunication procedure(s) in a wireless communication network. Based on radio technology of at least one serving node that enables at least part of the telecommunication procedure(s), the UE generates a TI and a classifier that discloses the type of the TI. The classifier enables distinguishing a TI value in a first radio technology from a TI value in a second radio technology. In addition the classifier enables a serving node that receives the classifier to identify a logic address of a disparate serving node without restriction in backwards compatibility amongst radio protocols utilized by the wireless communication network.

Characterization of temporary identifiers in a wireless communication network

Providing for inter-working between SMS network architectures and IMS network architectures in a mobile environment is described herein. By way of example, a next generation (NG) short message service center (SMSC) is provided that can receive SMS messages in mobile application protocol (MAP) and convert such messages to IMS protocol. In addition, the NG SMSC can also receive IMS data and convert the IMS data to an SMS MAP message. The NG SMSC can reference an IMS or an SMS location registry to determine a location of the target device, and convert from IMS to SMS MAP, and vice versa, as suitable. Accordingly, the NG SMSC can provide an efficient interface between legacy SMS and NG IMS network components while preserving legacy protocols associated with such networks.
