CallUp´s WAP-Gateway is a carrier-grade server enabling subscriber access to mobile and web services using mobile terminals.
The gateway retrieves the content from Web or WAP servers, converts HTML, XHTML and WML while optimizing the results to match the capabilities of the mobile terminals and finally delivers the content using WAP or IP protocols.
In addition, CallUp´s WAP-Gateway enables multimedia services based on the WAP protocol such as MMS and Java application download over the air (OTA).
CallUp´s WAP-Gateway scales up to support thousands of concurrent connections and it is based on 3GPP and OMA standards.
CallUp´s WAP-Gateway compliance
CallUp´s WAP-Gateway supports WAP v1.1, v1.2, v1.2.1, v1.3 and v2.0 WAP clients. WAP 2.0 clients are supported with HTTP/TCP (W-HTTP and W-TCP), or the WSP protocol stack.
The gateway was tested to conform with most of the WAP and web browsers. MIME-types are configurable. Any character set is supported.
The gateway provides session management and supports session and persistent cookies.
Security, Authentication and Access Control
CallUp´s WAP-Gateway supports secured and encrypted client-server transactions over SSL/WTLS protocols with RSA/ECC algorithms.
A rule based sub-system controls access of particular subscribers to certain domains. The gateway combines information from subscriber provisioning systems with HTTP_AUTH to control access to certain pages or folders.
Acting as the terminal proxy, the CallUp WAP-Gateway can interface a Radius accounting server to fetch user identity information such as the MSISDN number and act as an identity server for services like MMS.
A session timeout parameter controls the time that the connection will be maintained for idle clients.
Finally, Push Initiators are authenticated as well.
Content Billing and Session Screening
CallUp´s WAP-Gateway is located in a perfect position to screen all WAP or MMS traffic. Content screening can be used for detection of premium content forwarded by end users to perform:
- Content protection (forward lock for non-DRM compatible devices)
- Super distribution charge for premium content freely distributed by subscribers
- Generate CDRs with usage as well as content provider information
Bandwidth Optimization
CallUp´s WAP-Gateway can feed exiting MMSCs side by side with dedicated MMSCs – the WAP traffic is routed to the right server based on session headers.
The Gateway optimizes data bandwidth usage by inspecting all WAP/MMS traffic and measuring the bandwidth utilized by A2P and P2P transactions. Callup´s WAP-Gateway calculates the free bandwidth at any moment and responds to A2P platforms with information about the maximum load they can generate.
For example, with CallUp´s MMSC, an A2P dedicated MMS-Center, Callup´s WAP-Gateway dictates the number of notifications that can be sent to recipient users for bulk or push messages. This eliminates congestion in the IP network and prevents starvation of P2P transactions.
PPG
The CallUp WAP-Gateway comes with a built it Push Proxy Gateway serving Push Initiating services compliant with the PAP protocol. The services have control on the expiration of the message.
Scalability and High-Availability
The CallUp WAP-Gateway can be deployed on Unix or Windows 2003 operating environments. The services are deployed in N+1 scalable, redundant, high-availability, Active-Active load balanced fashion. With this architecture, the gateway is seamlessly scaleable, eliminating maintenance down-time.
