A telecommunications system and method is disclosed for adaptively configuring the cell structure of a cell having at least two carrier frequencies between an overlaid/underlaid (OL/UL) sub-cell structure and a normal cell structure based on the position of mobile stations within the cell. A Base Station Controller (BSC) for the cell determines the position of all of the mobile stations involved in a call connection within the cell relative to the cell site. If the number of mobile stations within a predefined distance from the cell site is greater than a channel threshold, the BSC adapts the cell configuration to the OL/UL sub-cell structure. The channel threshold is an operator-defined percentage of available channels (throughout the cell or within either the overlaid or underlaid cell). However, if the BSC determines that the percentage of mobile stations closer than the predefined distance is less than the channel threshold, the BSC maintains the normal cell structure.

A system and method for facilitating information interexchange between a wireless telecommunications system having at least one telecommunications device therein and an information service provider. A Business-to-Business (B2B) engine is connected to the telecommunications system for receiving realtime information related to a telecommunications device within the telecommunications system. This realtime information is provided by the B2B engine to the information service provider, which consequently provides content data to the telecommunications device within the telecommunications system.

Business to business engine and system for facilitating information interexchange using realtime data

A system, method, and apparatus for facilitating information interexchange between a telecommunications network serving a wireless communications device and an information service provider. A Business-to-Business (B2B) engine polls a telecommunications node associated with the telecommunications network serving the wireless communications device for real-time information. The telecommunications node responds by transmitting the requested real-time information to the B2B engine, which, in turn, provides the received real-time information to the information service provider. The information service provider, in turn, provides a service, tailored according to the real-time information received, to a subscriber associated with the wireless communications device.

A telecommunications system and method is disclosed for allowing a mobile station to determine whether or not to place a wireless call through an internet protocol (IP) based local area network (LAN) based upon broadcasted Quality of Service (QOS) information. The gatekeeper within the IP based LAN has access to the QOS information and periodically sends the QOS to the base station controller (BSC) functionality within the access node (AN) of the IP based LAN. The BSC functionality then transmits the QOS parameter on the System Information message via the base transceiver station (BTS) to the mobile stations served by the BTS. The mobile stations receive this QOS information and use this QOS information to decide upon a transport method to complete outgoing wireless calls.

A telecommunications system and method is disclosed for allowing business indoor mobile subscribers having multiple profiles to access both the business indoor network and the Public Land Mobile Network (PLMN) using one mobile terminal. To implement this dual-network service, a toggle feature can be provided to allow a business indoor mobile subscriber to choose between different subscriber profiles. Thus, if a mobile subscriber currently has the business indoor profile active and wishes to access the PLMN while roaming outside the business indoor cell(s), the mobile subscriber can initiate this toggle feature, and upon acknowledgment and authentication by the PLMN, the mobile subscriber can have access to the PLMN.

System and method for managing access in cellular network with multiple profiles

A broadcast message indicating the utilization level associated with Stand-alone Dedicated Control Channels (SDCCH) within a mobile telecommunications network serving a particular geographic area is transmitted over a broadcast channel. A plurality of mobile stations located within that particular geographic area monitoring the broadcast channel then receives the transmitted message. Thereafter, a mobile service request with a lower priority level than the indicated status level is queued by the associated mobile station and delayed until the channel utilization level rescinds to a network acceptable level.

Optimal use of logical channels within a mobile telecommunications network

A method and system for load balancing used in a mobile telecommunications network. The load balancing system includes a mobile services switching center and a first base station controller coupled to the mobile services switching center for managing a first plurality of cells. The load balancing system further includes a second base station controller coupled to the mobile services switching center for managing a second plurality of cells, where one cell of the first plurality of cells is adjacent to one cell of the second plurality of cells. The second base station controller includes a processor responsive to receiving a first load indication message from the first base station controller in order to determine whether to handover at least one ongoing call from the one cell of the second base station controller to the one cell of the first base station controller.

A telecommunications system and method is disclosed for providing adaptive thresholds for cell load sharing (CLS) based upon the current traffic situations. This can be accomplished by a Base Station Controller (BSC) monitoring the traffic load in a cell during a predetermined time period. If the traffic load is high for the entire time period, the CLS thresholds can be changed to maximize efficient channel resource utilization. In one embodiment, a look-up table can be used to set the thresholds for each cell based upon the traffic level, e.g., the percentage of idle channels, during the time period. Alternatively, the BSC can monitor only the traffic load in a cell with an usually high amount of traffic for the same time period. Thereafter, the BSC can change the thresholds in the high traffic cell and neighboring cells to maximize channel efficiency within the network.

A system, method and apparatus for activating and deactivating features in a mobile telecommunications system based upon the position of a mobile station. An accurate position of the mobile station is periodically determined and compared with stored coordinates for a specific location. Depending upon the outcome of this comparison, selected features are automatically activated or deactivated.

System, method and apparatus for automatic feature activation/deactivation based upon positioning

A telecommunications system and method is disclosed for collecting mobility information regarding mobile subscribers and providing this mobility information to telemarketing companies to generate extra revenue for cellular network operators. A telemarketing application can define a target area, which includes a cell or a number of cells that are of interest for the telemarketing application, and include this defined target area in a mobility request to an Operation and Support System (OSS) within the cellular network. The OSS instructs Mobile Switching Centers (MSCs) within the target area to log the movement of each MS located in the target area and store this mobility information in a Home Location Register (HLR) or Visitor Location Register (VLR). Once all the mobility information has been collected by the MSC's, the mobility information is passed onto the OSS, which can utilize filter parameters specified by the telemarketing application in order to generate tailored mobility information.

A system and method of providing preferential access to a cellular telecommunications network to a localized service area (LSA) subscriber who subscribes to a LSA and is operating a mobile station (MS) within the LSA. The cells which are included in the LSA are defined in a base station controller (BSC). The LSA subscriber's subscription information in the home location register (HLR) identifies any LSAs to which the subscriber subscribes. A Preferential Priority Indicator (PPI) property may also be set for the MS in the HLR. The PPI property indicates that the MS is to be granted preferential access whenever the PPI property is set. A Preferential Priority Network Indicator (PPN) property is also set in the BSC that indicates that the BSC supports use of the PPI property whenever the PPN property is set. When the MS originates a call, the BSC derives a second LSA-ID from the Cell-ID for the cell where the call originated. The BSC then determines whether the first LSA-ID matches the second LSA-ID, and in one embodiment, provides preferential access to the MS if the LSA-IDs match. In a second embodiment, the system, also determines whether the PPI property is set and whether the PPN property is set. Preferential access is provided to the MS upon determining that the first LSA-ID matches the second LSA-ID, the PPI property is set, and the PPN property is set.

System and method of providing preferential access to subscribers of localized service areas in a radio telecommunications network

A telecommunications system and method is disclosed for providing adaptive reservation of radio resources within a Localized Service Area (LSA) in order to achieve more efficient channel utilization of radio resources within the LSA. During a predefined time period, a base station controller (BSC) within the LSA scans for the percentage of radio resources used by public mobile subscriber and LSA mobile subscribers. The BSC compares the scanned percentage of radio resources with a radio resource usage profile stored in the BSC. If the scanned radio resource usage differs from the radio resource usage profile, the BSC sets new radio resource reservations for LSA and public mobile subscribers and updates the radio resource usage profile with the new radio resource reservations. The process is repeated to ensure maximum efficient radio resource usage within the LSA.

System and method for adaptive reservation of radio resources for cells

A telecommunications system and method for enabling a subscriber to determine the current time period, e.g., peak or off-peak, for that subscriber based upon the broadcasted system date and time prior to answering or placing a call on a mobile terminal. The Mobile Station (MS), or a Subscriber Identity Module (SIM) card within the MS, can be programmed with the relevant time periods for that subscriber, e.g., dates and hours for peak and off-peak time periods. In preferred embodiments of the present invention, a time period application within the SIM card receives the system information from the air interface and compares it with the stored time period information associated with the subscriber to determine the current time period. The SIM card can then instruct the MS to display the current time period, along with the amount of air time usage associated with that time period.

System and method for providing services based on broadcasted system

A 'load based priority' telecommunications system and method which provides efficient use of Traffic Channels (TCHs), while both meeting the subscriber's needs and producing revenue for the cellular operator. 'Load based priority' for the mobile subscribers consists of assigning a priority to the subscriber at the time of service activation. The subscriber can pay a low rate for lower priority subscriptions and a higher rate for higher priority subscriptions. The system continuously checks the traffic load on the TCH and broadcasts the current priority in the system information message to the mobile stations in the cell. For example, if the system broadcast message reads low priority, then all mobile subscribers will be able to make calls. However, if the system broadcast message reads high priority, then mobile subscribers who have purchased a lower priority subscription will not be able to make calls.

Load based priority for the mobile subscriber

A dialable directory number is assigned to a particular location area or cell area. A telecommunications user wanting to transmit user defined messages, such as a text message, to mobile stations within that location area or cell area transmits a signal encapsulating the message towards the assigned directory number. The transmitted signal is then routed through the conventional telecommunications network and delivered to the MSC providing mobile service to that particular location area or cell area. If the specified directory number is associated with a location area within a Public Land Mobile Network (PLMN), the serving MSC queries the attached visitor location register (VLR) to identify the mobile stations currently located within the specified location area. If the specified directory number is associated with a cell area, the serving MSC communicates with a base station controller (BSC) providing mobile service to that particular cell area. Thereinafter, the received message is transmitted using short message service (SMS) messages to each of the mobile stations determined to be located within the specified geographic area.
