## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to mobile internet access. More specifically, the present invention discloses an accurate, effective, and efficient system for content based charging, access barring, and network browsing, for pre-paid and post-paid subscribers of a wireless mobile communication network system.
2. Description of the Prior Art
With the rise in popularity of the internet and the technical advancements of mobile telephones, demand for wireless access to internet content is growing. Wireless access to the internet allows users, for example, to get their email or play online games, similarly to what they are provided with their office or home computer.
Currently, payment for the internet content is either by paying in advance or being billed after. Paying in advance is convenient for users concerned about controlling costs. Service is only provided for the amount paid in advance. This prevents unexpected or undesirable expense to the user. However, paying in advance is often inconvenient as the available balance is difficult for the user to monitor.
Paying after the service is convenient for users as access is fully available. However, use of services that is not carefully monitored can result in a large amount of money due after billing.
Furthermore, for the service and content providers, achieving a balance between convenience and quality of service to the user and proper billing and ease of system maintenance for the providers, is difficult to achieve.
Therefore, there is need for a system that efficiently controls access to the internet or free domain networks and accurately bills content charges for both pre-paid and post-paid subscribers of a wireless mobile communication network system.
SUMMARY OF THE INVENTION
To achieve these and other advantages and in order to overcome the disadvantages of the conventional method in accordance with the purpose of the invention as embodied and broadly described herein, the present invention provides an accurate, effective, and efficient system for content based charging, access barring, and network browsing, for pre-paid and post-paid subscribers of a wireless mobile communication network system.
Access to the internet or free domain networks are efficiently controlled and content charges are accurately billed for both pre-paid and post-paid subscribers. Additionally, a convenient and high quality service is provided to the user and the providers are given a proper billing solution that is efficiently maintained.
The present invention comprises: a gateway general packet radio service support node (GGSN) with service based content charge module (SBCC) and wireless application protocol (WAP) gateway IP filtering; a WAP gateway with a URL white list for pre-paid subscribers; a URL white list on a mediation gateway (MD) and the WAP gateway; and an MD comprising a GGSN call detail record (G-CDR) with Service Class, a WAP-CDR, and a URL white list.
A separate WAP gateway is provided for post-paid and pre-paid subscribers in a URL based configuration. The GGSN with SBCC is in an IP/Domain name based configuration and access point name (APN) configuration. Alternatively, a single WAP gateway is provided with the capability to determine pre-paid and post-paid subscribers according to the source IP address.
For post-paid subscribers, a WAP gateway (post-paid) IP address is deployed at the GGSN. Access is provided to the internet domain and GPRS free domain directly through the GGSN and to the internet domain and GPRS free domain through the WAP gateway. The GGSN further comprises a service based content charge (SBCC) module for recording GGSN call detail records.
For the content based charging solution for post-paid subscribers, the GGSN call detail record (G-CDR) comprises internet domain traffic by volume through the gateway GPRS Support Node (GGSN) to the internet domain, plus traffic by volume to the wireless application protocol (WAP) gateway, plus general packet radio service (GPRS) free domain traffic by volume through GGSN. The WAP-CDR comprises internet domain traffic by volume through the WAP gateway plus GPRS free domain traffic by volume through the WAP gateway. These two CDR's are provided to a mediation gateway (MD) and then filtered to remove the charge for GPRS free domain traffic by volume through the WAP gateway. The MD provides the filtered CDR to the billing system and the content data to the data warehouse (DW). Therefore, the post-paid subscriber is billed for internet domain traffic by volume through gateway GPRS Support Nodes (GGSN) to the internet domain, plus internet domain traffic by volume through the WAP gateway, plus GPRS free domain traffic by volume directly through the GGSN. The DW utilizes the content data to create analysis reports. A URL white list comprising a listing of accessible GPRS free domain content is located at the MD. The service platform (SP) or provising system is provided on the GPRS free domain and communicates appropriate URL white list information to the MD.
For pre-paid subscribers, a WAP gateway (pre-paid) IP address is deployed at the GGSN. For the content based charging solution for pre-paid subscribers, the G-CDR comprises traffic by volume through GGSN to the WAP gateway. The WAP-CDR comprises GPRS free domain traffic by volume through the WAP gateway. These CDR's are provided to the MD and then filtered for pre-paid users. The MD provides the content data to the DW.
For pre-paid subscribers, the internet domain is not available directly through the GGSN or the WAP gateway. Additionally, access to GPRS free domain traffic is only available through the WAP gateway and not directly through the GGSN. The URL white list comprising a listing of accessible GPRS free domain content for pre-paid subscribers is provided on the WAP gateway.
In order to block access to the internet domain for pre-paid subscribers, users are given a dedicated access point name (APN) to access the GGSN. A WAP gateway (pre-paid) IP address is deployed at the GGSN and access to the internet domain is barred by firewall and IP segment. The WAP gateway comprises a URL white list containing a list of available or accessible content or sites on the free GPRS domain. If the URL is not on the URL white list, access is barred. The service platform (SP) is provided on the GPRS free domain and communicates appropriate URL white list information to the WAP gateway.
For HTML browsing from a handset for post-paid subscribers, a WAP gateway (post-paid) IP address is deployed at the GGSN. The SP provides a message telling the user that a packet fee will be charged for HTML content. After which, access to the internet domain or GPRS free domain is provided.
For HTML browsing from a handset for pre-paid subscribers, a WAP gateway (pre-paid) IP address is deployed at the GGSN. Access to the internet domain, whether through the WAP gateway or directly through the GGSN is barred. Additionally, direct access to the GPRS free domain through the GGSN is barred and an error message is given indicating destination could not be reached or access to HTML content is denied. If the URL is in the URL white list located on the pre-paid WAP gateway, access to the GPRS free domain is given to pre-paid users. If the URL is not on the URL white list, access is barred.
Alternatively, the present invention comprises: a GGSN with SBCC patch and a URL white list; a WAP gateway with a URL white list for pre-paid subscribers; a URL white list on the SSBC and pre-paid WAP gateway; and a MD comprising a G-CDR and Service Class.
