Definitions
- the present invention relates to a system and a method for reducing the power consumption of a wireless terminal and increasing capacity of a wireless communication system without sacrificing functionality.
- a telephony terminal/endpoint When a telephony terminal/endpoint is connected to a source (for example, private branch exchange (PBX), router, private/public network, peer device) via wires or a cable, the source continuously updates the terminal with status and control messages, often at a frequency of several hundred times per second. These messages are used to control visual, audible, and tactile display elements (some examples of these elements might be alphanumeric displays, light emitting diodes (LEDs), ringers, icons).
- PBX private branch exchange
- router private/public network, peer device
- the terminal/endpoint is battery powered and is connected by means of a wireless communications network, such continuous updates can unnecessarily prevent the endpoint/terminal from entering “low(er) power mode”.
- continuously updating by the source of certain messages may provide no benefit at all to the wireless terminal user. For example, if the time-of-day clock of a terminal is capable of only displaying hours and minutes, no benefit results from having the source send time-of-day updates messages at a rate of more than once/minute.
- the present invention was developed in order to address the problems associated with conventional wireless devices that are described above.
- the algorithm of the present invention runs under program control in conjunction with the base station or source, by determining that the terminal is battery powered, determining the characteristics of the terminal, and then customizing and limiting the exchange of information transmitted from the base station to the wireless terminal so that the battery life of the terminal can be extended, while still maintaining the features and capabilities offered by the source.
- the algorithm succeeds in reducing the power consumption of the terminal without sacrificing features and/or capabilities that are provided by a communications protocol that supports display elements.
- an algorithm running at a base station determines whether an update message should be transmitted to the wireless terminal/endpoint based upon the content of the particular display element of the terminal/endpoint, coupled with the call state of the terminal/endpoint.
- the terminal/endpoint 10 communicates with base station 20 , and base station 20 is connected to the source 30 , the source being a public network, a private network, or a peer device for example.
- FIG. 1 shows a diagram of a base station connected to a source and communicating with a wireless terminal
- FIG. 2 shows examples of control messages and status indicators displayed on the wireless terminal
- FIG. 3 is a diagram showing the steps executed by the algorithm of the present invention when exchanging status and control messages with a wireless terminal.
- FIG. 4 is a diagram showing the display clearing algorithm of the present invention.
- FIG. 1 shows a diagram of a base station 20 communicating with a wireless terminal 10 .
- the base station is connected to a source 30 , which may include a public network, a private network, a peer device, etc.
- the algorithm described herein resided in the base station 20 .
- the base station can analyze information coming from the source 30 .
- the base station 20 can decide whether to pass the information on to the terminal/endpoint 10 .
- FIG. 2 shows examples of control messages displayed on the wireless terminal.
- the sample terminal/endpoint contains an alphanumeric display screen D, a number of status indicators (visual indicators S 1 -S 8 ), and display icons on the display screen D for indicating control messages.
- These display icons may show the information of an incoming call, a text message showing an alarm on a server, and an illuminated icon indicating an unread voice/email resides in the users mailbox, for example.
- Protocols used to supports telephony devices such as SIP (Session Initiated Protocol), H.323, ISDN BRI (Basic Rate Interface), and proprietary protocols, transmit/receive control information over signaling “channel” in order to control various display elements (i.e., visual, audible, and tactile).
- SIP Session Initiated Protocol
- H.323, ISDN BRI Basic Rate Interface
- proprietary protocols transmit/receive control information over signaling “channel” in order to control various display elements (i.e., visual, audible, and tactile).
- One of the features provided in one embodiment of the invention is the time-of-day clock. This is normally updated every minute on a wired terminal/endpoint. For wireless implementation described the invention, this display of the terminal shows only hours and minutes. In conventional systems prior to this invention, the display update capability of the system caused a continuous radio transmission from the radio base station to the terminal.
- the algorithm enables the base station to tailor the updates and/or limit the updates that are sent based upon several
- FIG. 3 shows the steps of analyzing each type of message received from the source.
- An “image” of the terminal/endpoint is kept in memory to verify any state changes that the source may send either as an update or simply as a “refresh”.
- the algorithm tracks other variables that describe the state of the terminal in order to see if status or control information should be transmitted to the terminal/endpoint.
- One such variable is the state of the voice connection. If a voice, or bearer “channel”, is currently established to the terminal then some messages that would otherwise be “filtered” are now transmitted due to the terminal, since it known to be already active.
- Another feature provided by wireless communications protocols is the ability to illuminate/extinguish visual indicators (LEDs) on the terminal 10 .
- LEDs visual indicators
- FIG. 2 This feature is shown with reference to Steps S 20 -S 23 of FIG. 3 .
- Visual indicators are used to convey status of voice connection, features and/or status indicators offered by the source. The updating and/or refreshing of these indicators is done a continuous basis by the source in order to ensure that the information contained in the terminal is up to date.
- the algorithm described herein stores the current state of all visual indicators of terminal 10 in the memory of the base station 20 . When an update comes from the source 30 , the base station 20 passes the information on to the wireless device 10 only if there is a change.
- the communications protocol also enables display messages to be sent to terminal 10 in response to certain events such as the making/receiving a call, pressing a button, or conveying status information such as the aforementioned time and data. (See Steps S 16 -S 19 of FIG. 3 .)
- the algorithm only sends these display updates if the terminal/phone 10 is NOT in an idle mode.
- the idle mode is when there is no (voice) “bearer” channel and the terminal 10 and source 30 have successfully negotiated the “tearing down” of a voice call.
- the invention also includes the capability of limiting the time that terminal 10 displays certain information. This is done to ensure that updates that are sent remain valid for only a fixed duration of time.
- a timer of the algorithm is set/reset based upon variables, such as those that are described in the sections above. Prior to the present invention, the display updates provided would remain on the screen until a subsequent update from the source occurred. Since the updates sent to the terminal by the algorithm of the present invention are intentionally less frequent, there needs to be a way to ensure the updates do not get “stale”, thereby invalidating the accuracy of the information.
- the timer solves that issue, as well as contributing to less power usage.
- FIG. 4 shows the steps of clearing the display of time sensitive user data such as a timer of day (TOD) clock or timers that indicate the length of a voice connection.
- TOD timer of day
- An advantage of the present invention is that the battery life of a wireless device can be extended while still providing the value-added features that a source affords its wireless phone users.
- the wireless terminal can exploit the value-added features offered by the system, for example, multi-line function, call forwarding, conferencing, call holding, and others, while still maintaining the extended battery life that wireless device user's require.
- the algorithm of the present invention may be applied to any base station implementation (for example, the source may be a private branch exchange (PBX), router, private/public network, peer device) and telephony protocol (for example, SIP, H.323, ISDN BRI).
- PBX private branch exchange
- the algorithm may be implemented in the fixed-part/base station portion of the radio link so it can be added to a system without modifying the software/firmware of the phone/terminal, thus extending the useful life of the source (base station), and deferring or reducing upgrade costs.
- the algorithm can be extended to any terminal connected to a switching device, such as a wireless EP endpoint (802.11 for example).
- a switching device such as a wireless EP endpoint (802.11 for example).
- the invention can be applied to an 802.11 base station as a way of saving battery life on an 802.11-based endpoint.
