摘要： Systems and methods are disclosed that determine whether incoming calls are in a home local calling area (LCA) in a wireless network. One embodiment comprises an LCA determination system that includes a processing system and a mapping data structure. The mapping data structure includes a plurality of entries that map a switch/cell identifier (e.g., an MSC/cellsiteID) to a set of LCA identifiers. For a call in a wireless network, the processing system receives a switch/cell identifier, masks the sector identifier from the switch/cell identifier, and searches the mapping data structure based on the masked switch/cell identifier to identify an associated set of LCA identifiers. The processing system then compares the set of LCA identifiers to a subscriber profile to determine if an LCA identifier matches. If there is a match, then the processing system determines that the call is in a home LCA.

摘要： Phonebook systems and associated methods are disclosed that provide a mechanism for protecting private information of a contact from being published in a network-based phonebook. A typical network-based phonebook service allows subscribers to set up network-based phonebooks, where each phonebook includes one or more contacts and associated contact information. Before contact information for a contact is included in a network-based phonebook for a subscriber, a phonebook system identifies privacy criteria for the contact. The privacy criteria may be predefined by the contact, predefined by the service provider, or predefined by another entity. The phonebook system then processes the privacy criteria to identify the contact information for the contact that is authorized to be included in the network-based phonebook. The processing system may then include the authorized contact information in the network-based phonebook, and block the unauthorized contact information from being included in the network-based phonebook.

摘要： Communication networks and associated methods are disclosed that provide a voicemail blocking service. A communication network of the invention comprises a network node and a voicemail system. The network node receives a call from a calling party to a subscriber of the voicemail blocking service, and attempts to connect the call to a communication device of the subscriber. If the subscriber does not answer the call, then the network node processes voicemail blocking information for the subscriber to determine whether the call is allowed to be routed to the voicemail system. If a determination is made that the call is not allowed to be routed to the voicemail system, then the network node blocks the call from being routed to the voicemail system. If a determination is made that the call is allowed to be routed to the voicemail system, then the network node routes the call to the voicemail system.

摘要： An intelligent-networked telecommunications system allows a customer to make a free telephone call after listening to a product or service advertisement. The customer reaches a product/service menu after dialing a telephone number with a special prefix reserved for Advertisement With Bonus Call (AWBC) service. The customer then chooses the advertisement of interest. After listening to the advertisement, the system allows the customer to enter a destination number for a free bonus telephone call. In the preferred embodiment, the bonus call is limited to a predefined duration monitored by a timer reset at the beginning of the bonus call. When the time limit is near, the system broadcasts this fact to both the calling party and the called party. At the expiration of the time limit, the call is automatically disconnected, and the customer can be returned to the AWBC product/service main menu. Charging the bonus call to the sponsor of the product/service advertisement to which the customer has listened completes the transaction.

摘要： An intelligent-networked telecommunication system avoids redundant billing for telephone transactions in which there is a billing conflict between the Intelligent Network (IN) and another component of the system by its Service Control Point (SCP) creating a service-dependent pseudo Calling Line Identifier (CLI). When a Pseudo CLI look-up table stored in the SCP database indicates that a pseudo CLI is to be created (based upon the Destination Number, DN, or the Service Key, SK), the SCP combines a prefix listed in the table with the Calling Party Number (CgPN) to form a pseudo CLI or create a totally new CLI number string. When the call is connected to the DN, the created pseudo CLI, rather than the original CLI, is transferred to the DN. A pseudo CLI is indicated where the IN is programmed to handle the billing of a particular transaction, and where the instrumentality of the DN (e.g., toll switch or special service platform) is also set up to handle billing. When the toll switch, special service platform, etc., attempts to bill for the transaction (already being billed by the IN) the pseudo CLI prevents it from billing an actual customer since no actual customer will have any of the pseudo CLIs. The service-dependent CLI also indicates to the toll switch, or special service platform, etc., that the current IN service call has already been billed through the IN.

摘要翻译： 智能网络电信系统避免了电话交易的冗余计费，其中智能网络（IN）与其服务控制点（SCP）的系统的另一个组件之间存在计费冲突，从而创建一个依赖服务的伪呼叫线路标识符 CLI）。 当存储在SCP数据库中的伪CLI查找表指示要创建伪CLI（基于目的地号码，DN或服务密钥SK）时，SCP将表中列出的前缀与 呼叫方号码（CgPN）形成一个伪CLI或创建一个全新的CLI号码字符串。 当呼叫连接到DN时，创建的虚拟CLI而不是原始CLI将被传送到DN。 指示伪CLI，其中IN被编程为处理特定事务的计费，并且其中DN的工具（例如，长途交换机或特殊服务平台）也被设置为处理计费。 当费用开关，特殊服务平台等尝试为交易（已经由IN计费）进行帐单时，伪CLI阻止其对实际客户进行计费，因为没有实际的客户将具有任何伪CLI。 服务相关的CLI还向收费交换机或特殊服务平台等指示当前IN服务呼叫已经通过IN来计费。

摘要： Centralized charging systems and methods are disclosed for providing offline charging and online charging for a plurality of network elements. The centralized charging system is implemented in a communication network between the network elements and offline/online charging systems. A network element interface of the centralized charging system receives charging request messages from CTFs in the network elements. An accounting data forwarding function processes charging data in the charging request messages to determine if offline or online charging is invoked for the services. For offline charging, the accounting data forwarding function generates offline accounting request messages that include the charging data. For online charging, the accounting data forwarding function generates online accounting request messages that include the charging data. The charging system interface then transmits the offline accounting request messages to the offline charging system, and transmits the online accounting request messages to the online charging system.
