In an access control system, a method and system for dynamic channel selection to select a channel for communication between a Wireless Access Point Module (WAPM) and a Wireless Panel Interface Module (WPIM). A number of communication channels are available. The WAPM attempts to communicate over a first channel and selects a second channel if the first channel is unsuccessful. The WPIM scans all the available channels so that communication may be established regardless of the channel chosen by the system. Alternatively, the available channels may be segmented into groups and an individual WAPM may be assigned to a group of channels rather than a single channel. |

A module interfaces a mobile communications network to a packet data network and is capable of implementing an Intelligent Network Service, for example, prepaid charging, for a packet-switched service for subscribers of the mobile communications network. A network interface module operative as such may obviate a need to configure (e.g., replace or upgrade) a packet-switching module so that the packet-switching module can implement one or more Intelligent Network Services. A network interface module may be operative to implement such prepaid charging in real-time. The network interface module may determine both a count and a time period from the prepaid balance, and compare the number of information units exchanged during the service and the duration of the service against the count and time period, respectively. An entry for a subscriber in a Subscriber Information Registry of a home mobile communications network may be defined such that when a subscriber roams into a visited mobile communications network, the network interface module of the home mobile communications network is used to implement a session between the mobile terminal of the subscriber and a node of a packet data network. As a result, one or more Intelligent Network Services (e.g., prepaid charging) for packet-switched services may be provided for the subscriber as the subscriber roams in other mobile communications networks. A Service Switching Function module of an mobile communications network may be operative to implement an Intelligent Network Service for packet-switched services by exchanging communications with an Service Switching Function module operative to implement the Intelligent Network Service only for circuit-switched voice services. Implementation of an Intelligent Network Service for a packet-switched service may be toggled between a packet-switching module and a network interface module, for example, in response to the packet-switched service being handed-off to or from the packet-switching module. |

A subscriber of a communications network is enabled to top-up an account for a multimedia service provided on the communications network while the service is being provided. Real-time prepaid charging may be applied to a multimedia service being provided to a subscriber of a communications network. Both a count and a time period may be determined from an account balance, and the number of information units exchanged during the service and the duration of the service may be compared against the count and time period, respectively. Further processing may be defined to be performed if either and/or both thresholds are reached. A subscriber of a communications network may be notified of a threshold amount of service being reached while the service is being provided using the same session as is being used to provide the service (in-band) or using a different session (out-of-band). Further, a subscriber may be notified of a threshold being reached using a Short Message Service (SMS) by sending an SMS message to the subscriber. A subscriber of a communications network may be enabled to top-up a service account while the service is being provided using the same session as is being used to provide the service (in-band) or using a different session (out-of-band). To notify the client that a threshold for a service has been reached and/or to enable the client to top-up, either in-band or out-of-band sessions may be used based on any of a number of factors, including a characteristic of the session in progress implementing the service, the capabilities of the user terminal, the capabilities of the application and application server providing the service, or any combination thereof. A session for providing a multimedia service may be implemented using a multimedia control protocol capable of controlling (e.g., initiating, maintaining and terminating) a session that includes the exchange of multimedia content, including audio, video, data or any combination thereof. For example, such protocol may be the Session Initiation Protocol (SIP). Service content transmitted from a server to a subscriber on the subscriber's user terminal may be buffered (e.g., cached) in a buffer while the subscriber is provided the opportunity to top-up the account. While the subscriber is being enabled to top-up a prepaid account for a service, a different billing method, for example, postpaid charging, may be applied for the service until the subscriber tops-up or until the opportunity to top-up has elapsed. |

A communication system having a wireless trunk for connecting multiple phone lines over wireless communication links to a cellular network comprises a central telephone switch, such as a private branch exchange or key system, connected through one or more trunk lines to a wireless access communication unit. The wireless access communication unit preferably comprises a separate subscriber interface for each trunk line from the central telephone switch. The wireless access communication unit collects data from each of the subscriber interfaces, formats the data into a format compatible with an over-the-air protocol, and transmits the information over one or more wireless channels to a cellular base station. The wireless access communication unit thereby connects calls received from the central telephone switch's trunk lines over a wireless trunk to a network. A controller within the wireless access communication unit interfaces the subscriber interfaces with a radio transceiver, and assists in the conversion of data from a format suitable for wireless transmission. The controller also assists in distributing data received over the wireless trunk to the separate subscriber interfaces, and converting the data to a format suitable for communication with the central telephone switch. Calls may be selectively routed by the central telephone switch over landlines, instead, to the wireless access communication unit, thereby bypassing landlines. |

A mobile communication system and a mobile station paging method are provided which are capable of sending a mobile station paging signal only to base station areas in which a mobile station to be paged for an incoming call might be present. The mobile communication system is provided with a location register 31, a mobile station paging signal transfer node 21 and base stations 11 to 13. The mobile station paging signal transfer node 21 receives a mobile station paging signal from the location register 31 which has identified the location area for paging a mobile station for an incoming call, and the mobile station paging signal transfer node 21 searches sublocation information to identify certain base stations to receive the mobile station paging signal. The sublocation information contains a number of mobile stations existing in a base station area classified into eight group numbers, and the group number for a mobile station to be paged is calculated based on the mobile station identification number which has been sent from the location register 31 together with the mobile station paging signal. The sublocation information is searched by an index key of the calculated group number for a mobile station to be paged, and if at least one mobile station is found in the corresponding group number, the mobile station paging signal is sent to this base station. The mobile station paging signal transfer node 21 repeats this procedure for all base stations 11 to 13 under its control. |
