Systems and methods are disclosed for performing online charging for text messages. One embodiment comprises a system that handles a Mobile Originated (MO) text message. The system receives a send request for the MO text message, and generates an online credit request for the MO text message. The system determines a type of originating network for the MO text message, and inserts an indicator of the originating network type in the online credit request. The system may also determine a type of terminating network for the MO text message, and insert an indicator of the terminating network type in the online credit request. The system then transmits the online credit request to an online charging system to charge for the MO text message.

Differential online charging for text messages based on network type

A network access system, e.g. a network hotspot, requires a mobile network access device, e.g. a smart phone or WiFi only device, to provide a network access standard designation and/or a device identification datum to gain access to network services. The network access standard designation may be provided by the mobile network access device to an online signup server via a EKU_key_purpose field of a PKCS10 certificate signing request. The device identification datum may be provided to the OSU via a subject field of the signing request. The OSU may require that the device identification datum be the same as a device identification datum provided by the mobile network access device prior to the mobile network access device requesting a signed network access certificate.

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.

Systems and methods are disclosed for interworking WAP text messages between 3GPP and 3GPP2 networks. One embodiment comprises a system that receives a WAP text message from a sending entity that supports 3GPP standards, where the WAP text message is in a 3GPP format. The system determines that a receiving entity for the WAP text message supports 3GPP2 standards, and converts the WAP text message from the 3GPP format to a 3GPP2 format. The system then transmits the WAP text message in the 3GPP2 format to the receiving entity.

Interface between 3GPP networks and 3GPP2 networks for WAP text messaging

Spam filtering methods and systems are provided for filtering spam SMS SMPP messages from an ESME to an SMSC associated with a wireless network, in which an anti-spam application receives SMPP SMS messages from the ESME and performs spam filtering prior to providing SMPP messages to the wireless network, with good messages being forwarded to the SMSC of the network and spam messages being discarded or persisted.

SMPP message processing for SMS spam filtering

Methods and systems are presented for filtering spam MAP SMS messages in an SS7 network, including mobile originated and mobile terminated MAP SMS messaging to mitigate spam-related traffic in the SS7 network. The system includes an anti-spam application () running on one or more network servers () that receives the MAP messages before routing to any SMSC or MSC, and classify these as spam or good. The good MAP SMS messages are then provided to the corresponding destinations by appropriate SMSC or MSC in the SS7 network, while the spam MAP SMS messages are not delivered to the SMSC.
