Filed:

Oct 11, 2006

Appl. No.:

12/089901

Inventors:

Christopher E. Caldwell - Woodstock GA, US
Janne P. Linkola - Espoo, FI

Assignee:

T-Mobile USA, Inc. - Bellevue WA

International Classification:

H04M 11/00

US Classification:

455406, 455423

Abstract:

A system and method for collaborating with a billing system is provided for use in a converged telecommunication network that includes a cellular telephone network and an IP-based network. During an IP-based call registration process, a mobile device communicates with a network controller over the IP-based network. The network controller accesses a database with the information provided by the mobile device and subsequently overloads values for an existing field in a call detail record (CDR). Upon completion of the call over the IP-based network, the network controller communicates the overloaded version of the CDR to an MSC which generates the final CDR that is used for billing. Any appropriate field of the CDR can be selected for overloading, such as for example an existing CGI record field from the CDR.

International Classification:

H04W 4/00
H04B 7/00

US Classification:

370338, 370328, 370330, 370340, 455525

Abstract:

A system and method for authorizing mobile devices to carrier networks via non-traditional entry points is described. In some examples, the system reviews a registration message sent during establishment of a communication session between the mobile device and the carrier's network to determine the type of access network used by the mobile device. In some cases, the system may identify the base station controller originating the registration message when determining whether the access request came from an IP-based network or other non-traditional entry point.

H04B 7/00

US Classification:

370338, 370328, 455405, 455525

Abstract:

A system and related method provide a registration request via an access point, wherein the access point is associated with a defined service zone. In response, an authorization signal to access telecommunications services is received. The authorization signal includes service zone name data for the service zone and/or at least one service zone icon indicator for the service zone. Further details are described herein.

International Classification:

H04W 72/00
H04L 12/26
H04L 12/28

US Classification:

455453, 370252, 3703952, 37039521

Abstract:

An access point management facility manages use of an access point configured for IP-based communications in a telecommunications system. The facility allows for the establishment of one or more static and/or dynamic parameters for limiting use of the access point for IP-based communications. The facility monitors traffic on the access point and determines whether any requests for use of the access point complies with the parameters for limiting use. The facility then denies or redirects a request for use of the access point if otherwise permitting the request would not comply with the parameters for limiting use of the access point.

Appl. No.:

Inventors:

Christopher E. Caldwell - Woodstock GA, US
Janne P. Linkola - Espoo, FI

Assignee:

T-Mobile USA, Inc. - Bellevue WA

International Classification:

H04M 11/00

US Classification:

455408, 4554221, 4554352, 370382, 370392

Abstract:

A subscriber communicates over an IP-based wireless telecommunications network through an access point. Identifiers associated with the access point (e. g. , MAC address IP address, FQDN. . . ) are stored in a database. Each access point is mapped into one or more service zones, where service zones are mapped to service types. The subscriber has a rate plan that is based on a selection of one or more service types. When a wireless connection between the subscriber and the IP-based wireless telecommunications network is established, the access point identifiers are used to retrieve a service zone ID from the database. Upon completion of the communication, a call detail record can be generated that includes the service zone ID for the communication. The billing system can then retrieve billing plan information to determine an appropriate rate for the subscriber based on the service zone ID.

International Classification:

H04M 11/00

US Classification:

370214, 370241, 370252, 370401, 370465

Abstract:

A method and system for reducing network load by selectively provisioning connections between an access point and a carrier network is disclosed. The access point supports voice and data connections over an IP network. The access point includes a network connection and a telephone connector capable of connecting to a standard landline telephone. The access point also includes at least one detection component that detects whether a landline telephone is plugged in to the telephone connector. The access point is configured to provision a voice connection through the IP network when it detects that a landline telephone is plugged in.

Christopher E. Caldwell - Woodstock GA, US

International Classification:

H04L 12/26

US Classification:

370252

Abstract:

A system and method manages call connections between mobile subscribers and an EP-based wireless telecommunications network through a wireless access point. Communications between the mobile subscribers and the IP-based wireless telecommunications network are initiated by a registration request. During the registration request various identifiers (IMSI, MAC address, IP Address, etc.) are communicated to the system. The system is arranged to log the identifiers and associate those identifiers with the entry point (e.g., the wireless access point) into the IP based wireless network. Call connections from the mobile subscribers are monitored for various throughput and call quality based metrics. Call handoffs between the IP-based wireless communications network and the cellular telephony network are managed by the system based on the monitored call quality and throughput metrics on a per-access point basis using the registered identifiers.
