Abstract
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.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
68 words
A mobile terminal reserve power system associated with a mobile terminal, comprising: means for detecting when the power level of said mobile terminal decreases beneath a predetermined reserve power level that is greater than an absolute minimum limit power level for operation; and means responsive to said detecting means for selectively preventing the reception of non-emergency transmissions when the power level decreases beneath said predetermined reserve power level.
Claim 2
Dependent Claim
68 words
A mobile terminal reserve power system associated with a mobile terminal, comprising: means for detecting when the power level of said mobile terminal decreases beneath a predetermined reserve power level that is greater than an absolute minimum limit power level for operation; and means responsive to said detecting means for selectively preventing the reception of non-emergency transmissions when the power level decreases beneath said predetermined reserve power level.
Claim 3
Dependent Claim
54 words
The mobile terminal reserve power system of claim 1 , wherein said means for preventing the reception of non-emergency transmissions comprises: means for receiving identification information for a particular incoming call connection from a network serving said mobile terminal and determining within said mobile terminal if said incoming call connection is an emergency call.
Claim 4
Dependent Claim
56 words
The mobile terminal reserve power system of claim 2 further comprising: means for storing at least one emergency number within said mobile station; means for comparing said received identification information received for said particular incoming call connection with said stored emergency number; and means for accepting said particular incoming call connection if there is a match.
Claim 5
Dependent Claim
43 words
The mobile terminal reserve power system of claim 1 , wherein said means for preventing the reception of non-emergency transmissions further comprises means for communicating with a network serving said mobile terminal data indicative of the current power state of said mobile terminal.
Claim 6
Dependent Claim
73 words
The mobile terminal reserve power system of claim 4 , wherein said transmission prevention means further comprises: means for storing at least one emergency number at said network serving said mobile terminal; means for comparing an incoming number associated with an incoming call connection with said stored emergency number to determine if there is a match; and means for preventing said incoming call connection towards said mobile terminal if there exists a match.
Claim 7
Dependent Claim
34 words
The mobile terminal reserve power system of claim 4 further comprising means for instructing said serving network to expect less frequent Location Update (LU) signals during a particular time period from said mobile terminal.
Claim 8
Independent Claim
75 words
A method for preserving battery power within a mobile terminal comprising the steps of: selecting a particular power level that is greater than an absolute minimum power level to operate said mobile terminal for establishing an emergency call connection; detecting when the power level associated with said mobile terminal decreases below said selected power level; and selectively preventing, in response to said step of detecting, reception of non-emergency incoming transmission associated with said mobile terminal.
Claim 9
Independent Claim
75 words
A method for preserving battery power within a mobile terminal comprising the steps of: selecting a particular power level that is greater than an absolute minimum power level to operate said mobile terminal for establishing an emergency call connection; detecting when the power level associated with said mobile terminal decreases below said selected power level; and selectively preventing, in response to said step of detecting, reception of non-emergency incoming transmission associated with said mobile terminal.
Claim 10
Dependent Claim
49 words
The method of claim 7 further comprising the steps of: receiving identification information associated with a particular incoming call connection from a telecommunications network serving said mobile station; determining whether said received identification information indicates an emergency call connection; allowing said incoming call connection in response to said determination.
Claim 11
Dependent Claim
51 words
The method of claim 8 further comprising the steps of: storing at least one emergency number within said mobile station; comparing said received identification information received for said particular incoming call connection with said stored emergency number; and means for accepting said particular incoming call connection if there is a match.
Claim 12
Dependent Claim
37 words
The method of claim 7 further comprising the steps of communicating, in response to said step of detecting, data indicative of said battery level associated with said mobile station to a telecommunications network serving said mobile station.
Claim 13
Dependent Claim
66 words
The method of claim 10 further comprising the steps of: storing a particular emergency number within said telecommunications network serving said mobile station; receiving a request to establish an incoming call connection toward said mobile station; comparing incoming identification number associated with said incoming call connection with said stored emergency number; and rejecting said request to establish said incoming call connection if there is no match.
Claim 14
Dependent Claim
27 words
The method of claim 10 further comprising the steps of requesting said serving network to expect a less frequent Location Update (LU) signal from said mobile station.
Claim 15
Dependent Claim
77 words
A mobile terminal reserve power system communicating with a telecommunications network serving a battery powered mobile terminal, comprising: a battery; a register for storing a certain value indicative of the absolute minimum power level associated with said battery for operation; a detector for detecting when the power level of said battery decreases beneath said certain value stored within said register; a processor for preventing the reception of non-emergency incoming transmission when said detector has made said detection.
Claim 16
Dependent Claim
77 words
A mobile terminal reserve power system communicating with a telecommunications network serving a battery powered mobile terminal, comprising: a battery; a register for storing a certain value indicative of the absolute minimum power level associated with said battery for operation; a detector for detecting when the power level of said battery decreases beneath said certain value stored within said register; a processor for preventing the reception of non-emergency incoming transmission when said detector has made said detection.
Claim 17
Dependent Claim
40 words
The mobile terminal reserve power system of claim 13 further comprising: a receiver for receiving identification information for a particular incoming call connection from said telecommunications network; and said processor determining whether said identification information represents an emergency call connection.
Claim 18

The mobile terminal reserve power system of claim 14 further comprising: a register for storing at least one emergency number; and said processor comparing said received identification number with said stored emergency number and preventing said incoming call connection if there is no match.
Claim 19
Dependent Claim
30 words
The mobile terminal reserve power system of claim 13 further comprising a transmitter for communicating data indicative of the current power level of said mobile terminal to said telecommunications network.
