If thefirst detection module 112 determines to activate an alarm, step S204 is executed. If thefirst detection module 112 determines not to activate an alarm, step S200 is repeated. - In one example, the
first detection module 112 may convert the detected charge status of thebackup power supply 114 into a numerical format, and determine if that number is lower than a predetermined value. If the numerical charge status of thebackup power supply 114 is lower than the predetermined value, thefirst detection module 112 determines that thebackup power supply 114 has too little charge remaining and activates the alarm. If the numerical charge status of thebackup power supply 114 is higher than or equal to the predetermined value, thefirst detection module 112 determines that thebackup power supply 114 is has sufficient charge remaining. - It should be understood that a plurality of predetermined values may be utilized to differentiate many charge statuses associated with different alarm or non-alarm conditions.
- The alarm means may comprise different tones, rings and messages. The alarm frequency may also be adjusted. For example, when charge status of the
backup power supply 114 gets lower, the frequency of alarms signals may increase such as from once every minute for 40% charge remaining to once every ten seconds for 10% charge remaining to impart a greater sense of urgency to a user. If the alarms are in the form of messages, they may comprise caller identification (caller ID, or caller number identification) information. Exemplary disclosure of different charge statuses and corresponding alarm means are shown in Table 1. -
TABLE 1 The first The second The third Charge status alarm means alarm means alarm means The first status The first tone The first ring The first caller ID The second The second tone The second ring The second status caller ID . . . . . . . . . . . . The Nth status The Nth tone The Nth ring The Nth caller ID - The alarms may comprise tones, rings and caller ID information. N is a positive integer greater than 2. The caller ID information may comprise characters, numbers, symbols or figures to represent a corresponding charge status. For example, a caller ID “CHARGE20” is utilized to indicate the charge status of the back power supply is 20% charged. The
first detection module 112 can determine charge status of thebackup power supply 114 and a caller ID information corresponding to the charge status. - In step S204, the
second detection module 115 detects work status of the telephone 100 (step S204) and determines whether thetelephone 100 is in an on-hook state or an off-hook state.

telephone 100 is on-hook, thetelephone module 111 alerts a user by one or more rings (step S210). In addition, thetelephone module 111 may also utilize caller ID format to transmit a charge status message of thebackup power supply 114. Upon receiving a charge status message of thebackup power supply 114, thetelephone 100 displays the message on thedisplay 101. - This is the way that the
communication device 110 can actively notify a telephone of charge status of thebackup power supply 114. The passive charge status alerting is explained next. - When the
telephone 100 sends a charge status query to thecommunication device 110, thecommunication device 110 receives the charge status query and responds to the query with a message indicating the charge status of thebackup power supply 114. Thetelephone 100 may call specific numbers to query the charge status. For example, thecommunication device 110 stores a digit map table, and each entry in the digit map table comprises a digit map. Thecommunication device 110 compares a called number sent by thetelephone 100 with the digit maps. If the called number conforms to a specific digit map, thecommunication device 110 takes the called number as a charge status query and responds to the query. - With reference to
FIG. 4 , thecommunication device 110 receives a specific number from the telephone 100 (step S300) and determines whether the number sent from thetelephone 100 conforms to a specific entry in the specific digit map table (step S302). If the number conforms to the specific entry, thefirst detection module 112 detects and determines the current charge status of the backup power supply 114 (step S304), and responds to the received number with a caller ID via thetelephone module 111 to notify thetelephone 100 of the current charge status message of thebackup power supply 114. - If the number sent from the
telephone 100 does not conform to any entry in the digit map table, thecommunication device 110 executes general telephone call out service in response to the received number (step S308). - In conclusion, the foregoing
communication device 110 may actively monitoring charge status of thebackup power supply 114, or passively receive charge status queries and respond thereto with charge status messages. The method of notifying charge status information may comprise different tones, rings, and messages. The frequency of charge status notifications may also be adjusted. - It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
