摘要： Communication networks and methods are disclosed for performing charging in LTE/EPC communication networks. In an LTE/EPC communication network, a PCRF stores charging rules for online and offline charging. To perform charging for a session, LTE network elements that are serving the session request charging rules from the PCRF. The PCRF identifies the charging rules, and assigns a unique LTE charging identifier for the session across all network elements in the LTE/EPC communication network. The LTE network elements receive the charging rules from the PCRF along with the LTE charging identifier for the session. The LTE network elements generate charging messages for the session, and insert the LTE charging identifier in the charging messages. The LTE network elements then transmit the charging messages to a charging system, such as an OCS or an OFCS. The OCS/OFCS may then correlate the charging messages for the session based on the LTE charging identifier.

摘要： Communication networks and methods are disclosed for performing online charging credit control in a visited network when a user is roaming. The visited network which is providing service to a roaming user includes a proxy online charging system (OCS) that communicates with a home OCS in a home network of the user. The proxy OCS transmits an online charging request message to a home OCS in a home network for the roaming user requesting charging information for the roaming user. The proxy OCS receives an online charging response message from the home OCS that includes the charging information for the roaming user. The proxy OCS then processes the charging information to perform credit control for one or more network elements in the visited network that is serving the session.

摘要： Charging systems and associated methods are disclosed that provide interim billing for a session in an IMS network. The charging system includes a charging data system that receives accounting messages from network elements serving the session in the IMS network, and generates partial CDRs for each network element based on the accounting messages. The charging data system also sets an aggregation/correlation timer. Responsive to an expiration of the aggregation/correlation timer, the charging data system aggregates the partial CDRs for each network element to generate an aggregated CDR for each network element. The charging system further includes a charging gateway system that, in further response to the expiration of the aggregation/correlation timer, correlates the aggregated CDRs to generate an interim consolidated CDR for the session, and transmits the interim consolidated CDR to a billing system. The billing system may then provide interim billing for the session based on the interim consolidated CDR.

摘要： Communication networks and methods are disclosed for performing online charging in LTE/EPC communication networks. In an LTE/EPC communication network, one or more LTE network elements connect to an Online Charging System (OCS) over an enhanced interface. The LTE network element that is serving a session for a mobile device triggers on a charging event, and generates a credit request message (e.g., Diameter CCR). The LTE network element identifies access information for the session indicating the type of access for the mobile device to the LTE/EPC communication network, and inserts the access information in the credit request message. Through the enhanced interface, the LTE network element is able to transmit the credit request message to the OCS with the access information. The access information may then be used in the OCS to determine a more accurate charging rate for the session.

摘要： A user equipment determines a set of licensed and unlicensed frequency bands that are available for wireless communication. The user equipment selects a first subset of the set as targets for a handover involving at least one unlicensed frequency band and transmits information indicating the first subset. A base station receives information indicating a first subset of a set of licensed and unlicensed frequency bands. The first subset are targets for a handover of user equipment involving at least one unlicensed frequency band. The base station selects a second subset based on the first subset and transmits information indicating the second subset.

摘要： Systems and methods for spam detection within electronic messages transported over a communication network. One embodiment is a spam center that connects to multiple entities of a communication network that handle electronic messages, such as text messages. The spam center receives spam reports from the entities that detect spam in prior electronic messages, analyzes the spam reports to generate spam filtering rules based on the spam detected in the prior electronic messages. The spam center then distributes the spam filtering rules to one or more of the entities. The entities may then use to spam filtering rules to filter spam out of electronic messages that subsequently received.
