International Classification:

H04W 4/02

US Classification:

370338, 4554042, 4554561

Abstract:

A wireless connection between a mobile device and an IP-based wireless telecommunications network is established when the mobile device registers with a network controller (NC) through an access point (AP). When a geographical position is needed for the mobile device (e. g. , a 911 call), messages are exchanged between the NC and a serving mobile location center (SMLC), where the SMLC retrieves information from a database that is used to identify the geographic position of the mobile device. The database can store a variety of information related to mobile devices such as: last known position, IP address, MAC address, a mobile or subscriber identifier (such as an International Mobile Subscriber Identity (IMSI)), last CGI, etc. The geographical position is communicated back to the NC, which can then forward the position information to a switch for processing such as for 911 calls.

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.

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.

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.

Abstract:

A facility for maintaining a subscriber history pertaining to the use of a mobile device with an IP-based telecommunications service offered by a service provider. When a connection request is made by a mobile device to access an IP-based telecommunications service, one or more identifiers associated with the requesting mobile device and access point are provided in the request and stored by the facility. In some cases, the identifiers are stored even if the mobile device is unable to, or not authorized to, access the telecommunications service. Additional parameters associated with the request from the mobile device, such as a time stamp and details of a subsequent telecommunications session, are also associated with the stored request. The history of requests to access the IP-based telecommunications service from the mobile device are maintained by the facility and provided to a service support provider.

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.
