US Patent:

6345180, Feb 5, 2002

Filed:

Dec 30, 1998

Appl. No.:

09/222968

Inventors:

Martin Reichelt - Plano TX

Assignee:

Ericsson Inc. - Plano TX

International Classification:

H04N 100

US Classification:

455404, 455343, 455574

Abstract:

A mobile terminal with a reserve power system is provided herein, wherein if the mobile terminal has detected that the power level of the power supply connected to it has fallen below a predetermined emergency power reserve level it will restrict its activities related to the reception of transmissions, such as voice calls, and activities related to contacting the network during stand-by, in order to protect the capability to place and receive calls to/from a default or user-specified set of numbers (e. g. , emergency numbers, number of spouse, number of parents etc. ). The restriction on the reception of transmissions can be handled by the network, by the mobile terminal or both.

International Classification:

H04M 1100

US Classification:

455421, 455456, 455435, 455436

Abstract:

A method, system, and apparatus enables a subscriber to be warned via the mobile terminal (MT) when the MT has moved into an invalid area during a call. The network monitors the location/position of the MT during a call. When the MT enters a region (e. g. , a cell) that is invalid because it is located within an invalid area, the network sends a message to the MT. The message may be, for example, a novel cause code in a Direct Transfer Application Part (DTAP) message that triggers a warning action by the MT when the network does not have access to the transmission reaching the MT. The message may alternatively be an announcement or tone sent directly to the MT when the network does have direct access to the transmission reaching the MT. The network also begins a timer. If the MT is returned to a valid area before the is timer expires, the call may be continued (and a message so indicating may optionally be sent to the MT from the network).

Assignee:

Ericsson Inc. - Research Triangle Park NC

International Classification:

H04J 322

US Classification:

370465, 370410, 379229, 709230

Abstract:

A system and method in a communications network for minimizing the number of attempts required to establish a communication between two nodes is disclosed. Each node maintains a database table composed of addresses of other nodes within the communications system. Associated with each nodal entry is a list of dialogue types that have been initiated with or terminated from the relevant node. Associated with each dialogue type entry is the most-advanced protocol version, such as the Mobile Application Part (MAP), that has been negotiated with the affiliated node for that dialogue type. When a first node wishes to initiate a dialogue with a second node, the first node checks the database table. The first node locates the second node in the table by address, locates the appropriate dialogue by type, and then determines the appropriate MAP version. If either the node or the specifically desired dialogue type is not within the database table, the first node attempts to establish the dialogue with the highest MAP version that the first node supports.

Assignee:

Ericsson Inc. - Plano TX

International Classification:

H04M 1100

US Classification:

455404, 455572, 455574

Abstract:

A mobile telephone with an emergency call capability protector monitors a battery power supply circuit with an emergency call reserve power detector to determine when the power remaining in the battery power supply circuit has decreased beneath a pre-selected minimum emergency call reserve power level that is greater than the absolute minimum level detected by a monitor and battery depletion detector. A microprocessor operating in accordance with a program stored in an emergency call capability program memory selectively inhibits, subject to override, the making of non-emergency calls and terminates ongoing non-emergency calls when said power detector determines that the power supply circuit has gone beneath said pre-selected minimum emergency call reserve power level.

US Classification:

37039521, 37039542, 370465, 455410

Abstract:

The present invention provides a system, method and apparatus for providing multiple quality of service classes to subscribers in a network by determining a subscriber's quality of service information by using a database containing quality of service information for each subscriber that has subscribed to one of the multiple quality of service classes, and storing the subscriber's quality of service information in a visitor location register where the subscriber is currently registered.

International Classification:

H04Q 7/20

US Classification:

455436000

Abstract:

The hybrid mobile terminal is engaged in an existing call through a serving one of a circuit switched or packet data wireless networks. The mobile terminal places a new call through the target one of the wireless networks, the new call having a predetermined called party identifier. In response to the called party identifier, the call is converted to a loop-back call directed to the mobile terminal through the serving wireless network, establishing a call path through the target wireless network. The mobile terminal accepts the loop-back call, and directs the existing call to connect to the call path through the target wireless network. The existing call through the original network is then dropped, effecting an inter-system handoff from the serving to the target wireless network.

International Classification:

H04Q 7/20

US Classification:

455433

Abstract:

In a mobile telecommunications network, a subscriber having a primary subscription on a home mobile network registers one or more flexible subscriber numbers on a secondary network that are associated with the primary subscription. A caller places a call to a subscriber through a serving network using the flexible subscriber number. The flexible subscriber number is translated into a primary MSISDN and the call is connected to the subscriber so that roaming charges to the subscriber are minimized.
