Appl. No.:

8/978956

Inventors:

Christopher H. Kingdon - Garland TX
Bagher R. Zadeh - Dallas TX
Maya Roel-Ng - Plano TX
Stephen Hayes - Carrollton TX

Assignee:

Ericsson Inc. - Research Triangle Park NC

International Classification:

H04Q 720

US Classification:

455433

Abstract:

A telecommunications system and method is disclosed for determining the address of both the home and serving Mobile Positioning Centers (MPCs). Each Mobile Switching Center/Visitor Location Register (MSC/VLR) and Home Location Register (HLR) within a Public Land Mobile Network (PLMN) will be provided with the MPC address that is valid for its PLMN. When a Mobile Station (MS) roams into a new (serving) PLMN, a Location Update is performed by the serving MSC/VLR to the Home Location Register (HLR). The MPC address for the serving MSC/VLR will be included in every location update operation to the HLR, which can then store this serving MPC address in the subscriber's HLR record. Furthermore, the home MPC address, valid for the PLMN of the HLR, is included in every subscriber data transfer operation from the HLR to the serving MSC/VLR, which can then store this home MPC address, in the subscriber's VLR record.

International Classification:

H04Q 720

US Classification:

455456

Abstract:

A telecommunications system and method is disclosed for implementing Location Override Key(s) (LOKs) within location services in order to determine whether certain checks on subscriber limitations and/or system default behavior are applicable or not for a particular location request. Each LOK can either have the value override or not override associated therewith, and each Location Application (LA) can be associated with a particular value of an LOK. In addition, an LOK can be accompanied by one or more additional parameters related to the particular LOK. For example, location services can provide LAs with a Privacy Override Key (POK), which can have a value of "override" or "not override". If the POK is set to "override", the privacy settings of the subscriber to be positioned shall be overridden for the particular positioning request in most cases only if the subscriber to be positioned is in the same Public Land Mobile Network (PLMN) as the Gateway Mobile Location Center (GMLC) that received the positioning request.

Ericsson Inc. - Research Triangle Park NC

International Classification:

H04Q 720

US Classification:

455457

Abstract:

A telecommunications system and method is disclosed which utilizes a terminal-based browser, such as the Wireless Application Protocol (WAP) "deck", within a Mobile Station (MS) to connect the MS to web-based location services and to a Mobile Positioning Center (MPC). Terminal based browsers, such as WAP "deck", allow for the graphical presentation of the current location of the MS on a display on the MS and provide an interactive user dialog, which permits the mobile subscriber to determine the format of the graphical presentation of the current location of the MS.

Assignee:

Ericsson Inc. - Research Triangle Park NC

International Classification:

H04M 1500

US Classification:

375116

Abstract:

A telecommunications switch serving a roaming mobile station transports the resulting billing records by setting up a communication link with an administrative billing center connected to a Signaling System No. 7 (SS7) telecommunications network by utilizing Transaction Capabilities Application Part (TCAP) signals. Once the connection is established between the telecommunication switch and the administrative billing center, Data Message handler (DMH) formatted data are stored into the SS7 TCAP Invoke signal by the telecommunication switch and transported to the administrative billing center via the SS7 telecommunications network.

Theodore Havinis - Plano TX

Assignee:

Ericsson Inc. - Research Triangle Park NC

International Classification:

H04Q 720

US Classification:

455433

Abstract:

A telecommunications system and method is disclosed for allowing a Gateway Mobile Positioning Center (GMPC) to route positioning requests to the Public Land Mobile Network (PLMN) where the subscriber is currently located without the need for storing the subscriber's serving Mobile Positioning Center (MPC) address in the Home Location Register (HLR). When an external Requesting Application (RA) wants to locate a particular Mobile Station (MS), the RA contacts the GMPC, and provides the directory number of the subscriber that needs to be located. The GMPC then sends a request for routing information, e. g. , the address of the serving Mobile Switching Center (MSC), to the subscriber's HLR. The HLR then returns the routing information to the GMPC, which can then send the positioning request to the serving MSC, using the MSC address. The serving MSC can then route the positioning request to the serving Mobile Positioning Center.

Assignee:

Ericsson Inc. - Research Triangle Park NC

International Classification:

H04Q 720

US Classification:

455456

Abstract:

A telecommunications system and method is disclosed for allowing an application requesting positioning of a mobile terminal to indicate the quality of positioning information desired, e. g. , timeliness, accuracy, etc. In addition, prior to performing the positioning, the cellular network can determine whether the quality of service requested can be achieved, and if so, return the positioning information along with a message indicating that the quality of service requested was achieved. However, if the quality of service requested cannot be achieved, a failure message is sent to the requesting application and the positioning is not performed.

Ericsson Inc. - Research Triangle Park NC

International Classification:

H04Q 720

US Classification:

455456

Abstract:

A telecommunications system and method is disclosed for allowing a cellular network to determine the optimum positioning method, having knowledge of all available network-based and terminal-based positioning methods. This can be accomplished by the Mobile Station (MS) sending to the Mobile Switching Center/Visitor Location Register (MSC/VLR) a list of terminal-based positioning methods that the MS is capable of performing. This list can, in turn, be forwarded to the Mobile Positioning Center (MPC) for determination of the optimum positioning method. For example, in a GSM network, the MS CLASSMARK information, which is sent to the MSC/VLR when the MS registers with the MSC/VLR, can be extended to include the MS's positioning capabilities.
