System and method for providing supplementary services (SS) in an integrated telecommunications network

A system and method of service provisioning in an integrated telecommunications network having a packet-switched network portion (PSN) and a circuit-switched network (CSN) portion with a gateway disposed therebetween. A service node comprising a Service Control Point (SCP), a Service Data Point (SDP), or both, is provided with an interface operable with the PSN portion. A first entity (e.g., served entity) is capable of accessing the service node for the purpose of invoking a service. A return result from the service node is provided, based on the decision of what action is to be taken with respect to the service request, to the first entity which then determines how the action is to be effectuated. An indication is thereafter provided by the first entity to a second entity (e.g., re-routing entity) preferably using H.450.X messages. In response, the second entity (i.e., re-routing or switching entity) takes an appropriate service action based on the return result obtained from the service node. In a presently preferred exemplary embodiment, legacy service nodes built on the basis of WIN/IN service architecture are utilized for the provisioning of Value-Added Services (VAS) or Supplementary Services (SS) in VoIP networks operable with the H.450.X Recommendations.

Virtual Internet-of-things gateway system capable of realizing multiprotocol and network self-adapting

InactiveCN102045896ABroad network applicabilityMeet development needsWireless communicationWide areaControl layer
The invention discloses a virtual Internet-of-things gateway system capable of realizing multiprotocol and network self-adapting; and the gateway system uses a virtual Internet-of-things gateway to connect a sensor network with a traditional communication network and realize the protocol conversions of different types of sensor networks, equipment local interconnect and remote control. The invention is characterized in that the virtual Internet-of-things gateway contains a sensing access module in a sensing access layer, a protocol adaptation module and a network element service module which are in a protocol adaptation layer, a thing-connecting service control module in a control layer, and a heterogeneous network access module in a wide area access layer; the entire system adopts the virtual gateway method; the gateway equipment of the virtual Internet-of-things gateway system are arranged and only a plurality of physical interfaces are required to be added without greatly changing the internal circuit structure, thus the various demands of the future network can be satisfied and the development demand of the future Internet of things can be satisfied; and the incompatibility problem of the existing common gateway to the future Internet of things is effective solved, thus the gateway in the virtual gateway system has wide network applicability.

System and method of implementing an interactive callback feature in a radio telecommunications network

A system and method in a radio telecommunications network for interactively providing a calling party with a choice of call handling options when a called mobile station (MS) is either busy or inactive. When a call is received for the called MS in the network, a home location register (HLR) determines the status of the called MS (i.e., whether the called MS is available, inactive, or busy). If the called MS is inactive or busy, the status is sent to a service control point (SCP) which generates a plurality of call handling options based upon the determined status of the called MS. The call handling options are provided to the calling party in an interactive prompting process which may be in the form of a menu display or voice prompting. The calling party then selects a call handling option which is forwarded to the SCP. The calling party may instruct the network to automatically set up a call with the called MS if the called MS is reactivated within a specified period of time. The SCP determines actions required to execute the selected call handling option, and executes the determined actions. Call setup between the calling party and the called MS is triggered when the called MS registers with the network. If the time period expires before the called MS registers, the calling party is notified and may extend the time period or record a voice mail message.

Call admission control for Wi-Fi

Call admission control within a wireless network is implemented using a service controller that manages a set of access points. The call admission control (CAC) function for a given access point determines whether the access point has sufficient unused bandwidth to handle an additional call. The service controller makes this determination by monitoring the access points and evaluating certain probability functions and load conditions. In one embodiment, a determination of whether the access point has sufficient unused bandwidth to handle an additional call is a function of two (2) independent probabilities: (i) a probability of an active session moving to the access point from one or more neighbor access points, and (ii) a probability of an idle mobile device already associated with the access point entering into a new active session by initiating an inbound or outbound call. According to another aspect, the service controller issues and manages “call admission credits” among the set of access points, where a call admission credit value indicates a number of calls that idle mobile devices associated with the access point may initiate from the AP. The call admission credits value is a function of a determined load on the AP, and a mobility probability, which is a probability of an active call moving to the access point from one or more neighbor access points. The call admission credit value for the access point is adjusted as a function of a change of the load or in the mobility probability.
