`METHOD AND APPARATUS FOR
`INCOMING CALL REJECTION
`
`CLAIM OF PRIORITY FROM A COPENDING
`PROVISIONAL PATENT APPLICATION
`
`Priority is herewith claimed under 35 U.S.C. §119(e) from
`copending Provisional Patent Application 60/086,032,filed
`May 19, 1998, entitled “Incoming Call Rejection,” by Justin
`Beghtol and Kenneth Mar. The disclosure of this Provisional
`Patent Application is incorporated by reference herein in its
`entirety.
`
`FIELD OF INVENTION
`
`The present invention relates generally to call processing
`techniques in cellular telecommunications systems. More
`particularly, the present invention relates to apparatus, and
`associated method, for rejecting incoming calls to a mobile
`communications device within a cellular telecommunica-
`
`tions system.
`
`BACKGROUND OF THE INVENTION
`
`Wireless telecommunications systems provide a conve-
`nient way for users to communicate when landline phones
`are unavailable. What was once an expensive luxury is now
`an affordable convenience. By simply carrying a small,
`lightweight mobile communications device, users may place
`or receive calls of excellent quality in any geographic region
`offering such wireless service.
`Typically, wireless telecommunications systems are made
`up of a series of base stations connected to landline tele-
`communications networks through the use of base station
`controllers. The base stations have the capacity to commu-
`nicate with each other via the base station controllers and to
`establish a fixed number of radio frequency (RF) commu-
`nications channels with remote mobile phones. The RF
`communications channels act as a conduit by which the
`mobile phones may ultimately communicate with landline
`phones. Thus, as long as a mobile user remains within the
`geographic coverage area of the wireless system, commu-
`nication with other mobile and landline users is possible.
`To standardize the operation of wireless systems, several
`communication implementations have been developed. One
`such implementation, currently used in numerous wireless
`communication system deployments,
`is known as Code
`Division Multiple Access (CDMA). This communication
`technique is described under the TIA/EIA/IS-95-A standard
`(IS-95). Accordingly, the IS-95 standard is incorporated by
`reference in its entirety so as to provide the reader with
`adequate background information regarding mobile phone
`operation in an IS-95 telecommunications environment. As
`defined in the IS-95 standard, analog voice signals are
`converted to the digital domain, orthogonally encoded and
`then spread by a pseudo-random spreading signal so as to
`occupy a 1.23 MHz frequency band. From this spread signal,
`inphase and quadrature phase signals are generated which
`are then combined and modulated onto RFcarrier signals for
`transmission between remote mobilestations and fixed base
`stations.
`
`Current wireless systems allow landline users to place and
`receive calls with mobile phone users. Additionally, mobile
`phone users can place and receive calls with other mobile
`phone users. Fixed base stations facilitate these calls by
`routing the calls between users and handling necessary
`overhead activities required to establish the RF communi-
`cations channels used to conductthe calls.

`Typically, when a landline user calls a mobile phoneuser,
`the base station acts as an intermediary by alerting the
`mobile of the attempted call via at least one RF channel.
`After alerting the mobile, the base station waits for a fixed
`time period, which defines a ringing cycle,
`to receive a
`response from the mobile. The responseindicates the mobile
`is ready to accept the call. If the mobile does not respond
`within the ringing cycle time period, the base station releases
`the call by terminating the call alert
`to the mobile and
`signaling to the caller that the mobile is unavailable. During
`the ringing cycle, the mobile phone produces an audible
`ringing or mechanical vibration to alert the mobile phone
`user of the incomingcall. If the mobile phone user decides
`to answer the incoming call, a response is sent from the
`mobile to the base station indicating that the call is to be
`accepted. The base station then sets up a connection on the
`existing RF channel or establishes a second RF channel
`where the call will ultimately be connected.
`Included in the call alert to the mobile phone may be
`identification information about
`the caller, sometimes
`referred to as caller ID. This identification information can
`be displayed by the mobile phoneallowing the mobile phone
`user to determine whois calling before the call is answered.
`If the mobile phone user decides not to receive calls from
`specific callers, the identification information can be viewed,
`and if desired, the incoming call can be left unanswered for
`the entire ringing cycle.
`Oneof the major benefits to users of mobile phonesis the
`ability to place or receive calls without being restricted to a
`fixed location as when using a landline phone. So long as the
`mobile phone maintains an RF communication channel with
`at least one base station, communication services are gen-
`erally available. This allows mobile users to send and
`receive calls when away from their homeoroffice and even
`while traveling in automobiles.
`However, having accessibility to instant communications
`may at times have undesirable consequences. In particular,
`unless the mobile phone is powered off, there may be no
`action a user may take to prevent the phone from proceeding
`through the entire ringing cycle. This meansthat for every
`unanswered incomingcall, the phone will ring for the entire
`ringing cycle until the call is released by the base station.
`Even if the user is able to mute the audible ringing, the call
`is still processed by the phone until released, which may
`prevent the phone from handling other calls. There may also
`be times when a user desires to refuse all communications
`from certain callers. Such times may occur when prank
`callers or telemarketers repeatedly call or when users simply
`do not wantto receive calls originating from specific calling
`stations. Unfortunately, present systems do not allow mobile
`phonesto refuse to accept calls nor do they provide mobile
`phoneusers with a rejection-on-demand capability to imme-
`diately reject any incoming call as desired.
`Mobile phone systems have also adopted some of the
`features available in landline systems. For instance, a call-
`waiting feature may be implemented in a mobile phone
`system. During operation of call waiting, a user of a mobile
`phone may be connected and in active communication with
`a first caller when a second caller attempts a call to the same
`mobile phone. Instead of the second caller getting an imme-
`diate busy signal, a ringing cycle occurs where the mobile
`phone user receives a call alert indicating that there is an
`incoming call. The mobile phone user may then switch over
`to the second call and putthefirst call on hold, or may ignore
`the second call and continue on the first call. If the second
`call is not answered, the call alert to the mobile phone user
`will continue for a time period defining the ringing cycle.

`Unless the mobile phone user answers the secondcall, there
`is currently no way to terminate the call alert until
`the
`ringing cycle is complete.
`There currently exists a need in the mobile communica-
`tions industry for a method and apparatus wherein a user of
`a mobile phone has the capability to reject an incomingcall.
`Such a method and apparatus should provide the user an
`automatic modeof rejection and a manual modeofrejection.
`The automatic mode should allow the user to preprogram the
`mobile phone with information descriptive of calling sta-
`tions whosecalls are to be rejected. When an incomingcall
`from a pre-selected calling station is detected, the mobile
`phone should automatically reject
`the call. The prepro-
`grammed information should include wild card characters,
`thereby allowing entire groups of calling stations to be
`rejected from a single entry.
`In the manual mode of
`operation, the method and apparatus should allow a user to
`manually reject any incomingcall as desired. Thus, the user
`can conveniently and effectively screen incoming calls,
`prevent undesirable audible ringing and minimize unneces-
`sary utilization of the phone.

`immediately actuate the input actuator. This causes the
`message processor to immediately transmit the rejection
`message to the base station. Once the base station receives
`the rejection message,the call is released by the basestation
`andthecaller is notified of the unavailability of the mobile.
`The method and apparatus is especially suited to provide
`convenience to the mobile user by allowing unwanted calls
`to be easily rejected.
`In these and other aspects, therefore, a method ofselect-
`ably rejecting an incoming call to a mobile phoneis pro-
`vided. The mobile phone hasa transceiver circuit for trans-
`mitting and receiving transmissions with a remote
`transceiver. An incoming transmission is selectively rejected
`in a process beginning when the incoming transmission from
`the remote transceiver is received by the mobile phone. A
`determination is made at
`the mobile phone whether the
`incoming transmission is to be rejected. If it is determined
`that the incoming transmission is to be rejected, a rejection
`messageis transmitted to the remote transceiver, wherein the
`rejection messageindicates to the remote transceiverthat the
`incoming transmission is to be rejected.

`DETAILED DESCRIPTION OF A PREFERRED
`EMBODIMENT
`
`The present invention provides a method and apparatus
`for rejecting calls to a mobile communications device.
`Incoming calls received by the mobile device may contain
`information that is descriptive of the origin of the call. Based
`on the descriptive information, automatic rejection can
`occur. Additionally, a manual rejection feature is provided to
`allow the user to reject any call as desired.
`In an embodiment of the invention,
`the mobile phone
`comprises an input actuator, a rejection memory and a
`message processor. The rejection memory contains informa-
`tion descriptive of calling stations whose calls are to be
`rejected. In the automatic mode, identification information
`associated with an incoming call is compared with identi-
`fication information stored in the rejection memory.A deter-
`mination is made, and if the incomingcall is to be rejected,
`the message processor automatically transmits a rejection
`message from the mobile station to the base station. In the
`manual mode, upon receipt of an incomingcall, the user may

`In a telecommunications system operating according to
`the TIA/ETA/IS-95-A standard, when a remote mobile sta-
`tion is powered on, a registration process occurs. The
`registration process comprises a series of messages sent
`between the base station and the remote mobile station over
`communication channel 124. Registration allows the mobile
`station to obtain system parameters from the base station
`regarding operation of the telecommunications system. Reg-
`istration also allows the base station to determine which
`
`mobile stations are operating in the base station’s geo-
`graphic area. After the registration process is complete, the
`mobile station may enter a standby mode where it waits to
`process incoming and outgoing calls. The registration pro-
`cess is well known to those skilled in the art and is not
`relevant to the disclosed embodiment of the present inven-
`tion. Therefore, the registration messaging sequence will not
`be discussed in detail. However, the reader mayrefer to the
`IS-95 standard for a complete description.
`Referring again to FIG. 1, rejection memory 104 is used
`to store information identifying callers whosecalls are to be
`automatically rejected. The information in rejection memory
`104 may reference individual callers,
`lists of callers or
`contain “wild card” characters referencing entire groups of
`callers. Partial entries may also be used wherein,
`for
`example, a few numbersare used, such as 234, to reject all
`calls from originating stations having at least the numbers
`234 included in their complete numbers. Stored information
`may also contain alphanumeric characters, such as the name
`of the calling party or other information used to identify the
`calling party or calling station. This capability allows the
`invention to operate more efficiently as more caller identi-
`fication information becomesavailable for use. Information
`
`may be entered into the rejection memory through user
`inputs, such as inputs entered on a keypad 112. These inputs
`may be received by controller 102 and then input
`into
`rejection memory 104. Additionally, a computer interface
`such as a hardwired connection or an infrared (IR) link may
`be used to enter information into rejection memory 104.
`Information may also be downloaded to the mobile station
`from a network such as a wireless telecommunications
`network for entry into rejection memory 104. In this method
`of entry, rejection information is received at receiver 118,
`passed to message processor 108, sent to controller 102 and
`then entered into rejection memory 104.
`Referring now to FIG. 2,
`therein is depicted a call
`processing flow diagram 200 according to an embodiment of
`the present invention. Call flow diagram 200 illustrates how
`a call to a mobile station may be automatically or manually
`rejected. In the embodiment, the mobile station begins in the
`standby modeat block 202 where it waits to process calls.
`Entering the standby mode may occur, for example, after
`completion of the registration process described above.
`When in the standby mode, the user can enter information
`descriptive of calls to be automatically rejected into the
`rejection memory 104 as shownat block 204. The user can
`accomplish this through the use of keypad 112, wherein
`controller 102 receives user input from keypad 112 and
`stores the information into rejection memory 104.
`After rejection information has been placed in the rejec-
`tion memory, an indication of an incoming call may be
`received as shownat block 206. The incoming call indica-
`tion is received at receiver 118 via communication channel
`124. The incoming call indication may contain information
`aboutthe origin ofthe call, such as the caller ID information
`described above. At block 208 a determination is made
`whetheror not to automatically reject the incoming call. The
`determination can be made when the information about the

`incomingcall received at receiver 118 is sent to determiner
`106 via message processor 108. In addition, information
`aboutcalls to be rejected is received at determiner 106 from
`rejection memory 104. Determiner 106 then determines if
`the call is to be rejected by utilizing one or more of the
`comparison techniques described above. If it is determined
`that the call is to be rejected, a rejection messageis trans-
`mitted as shownat block 216 when determiner 106 informs
`
`message processor 108 to generate a rejection message and
`sendit to transmitter 116 for transmissionto the base station.
`After receiving the rejection message,
`the base station
`releasesthe call from the mobile as shownat block 218. The
`release occurs whenthe base station sends a release message
`to the mobile phone over communication channel 124.
`Receiver 118 receives the release message andtransfers it to
`message processor 108 and further to controller 102. After
`controller 102 receives the release message, it responds by
`re-initializing the call process to return to block 202 where
`the phone enters the standby mode again. In the meantime,
`the base station may terminate the incomingcall or transfer
`the call to a voice messaging system as shownat block 220.
`If a determination is made at block 208that the call is not
`to be automatically rejected, a call alert is activated and the
`user is given the opportunity to manually reject the call at
`block 210. The call alert occurs when controller 102 displays
`the incoming call identification information on display 110
`and activates the call indicator 114. Call indicator 114 is
`
`capable of generating rings, tones or other audible sounds, as
`well as mechanical vibration or other physical indications
`detectable by the mobile phoneuser. If the user decides to
`manually reject the call, the user indicates this to the phone
`by, for example, pressing a button on keypad 112, or some
`other available input actuator,
`thereby providing a user
`interaction as shown at block 214. A user interaction at
`
`keypad 112 is received at controller 102 which in turn directs
`message processor 108 to send the rejection message to
`transmitter 116 for transmission to the base station. As
`
`before, when the basestation receives the rejection message,
`the call will be released.
`
`If the user does not want to manually reject the call at
`block 210, the call is processed normally as shown at block
`212. This meansthe user has the option to answerthe call or
`let it continue to ring. The user may answer the call by
`entering a user input on keypad 112, for example. If the user
`does not answerafter a fixed period of time, for example, a
`ringing cycle, a time out will occur and the base station will
`release the call.
`
`The rejection message is used to notify the base station
`that the mobile phone user would like to immediately reject
`the attempted incomingcall. In a cellular system operating
`according to the IS-95 standard, a rejection message could
`be incorporated under IS-95 section 6.7.4, Reverse Traffic
`Channel
`Information Records. On the reverse traffic
`channel, information records may be included in a Flash
`with Information Message. FIG. 3a depicts an information
`record type 300 known as a Feature Indicator, which could
`be used to provide the rejection message in a Flash with
`Information Message. Under the IS-95 standard, section
`6.7.4.1 defines a Feature Indicator message. Referring to
`FIG. 3b,
`therein is depicted message format 302 for the
`Feature Indicator, which can be used to indicate a rejection
`messageto the basestation. In this format, the first four bits
`may be used to signify call rejection by setting them to the
`value of “0000.” The next four bits are reserved. The
`
`the
`rejection message indicates to the base station that
`mobile phone user desires to have the attempted incoming
`call immediately rejected. This is different from merely

`indicating to the base station that the mobile phone cannot
`receive the call becauseit is busy. By transmitting a rejection
`messageto the basestation, the base station can distinguish
`between a busy message and a rejection message and
`thereby processthe call as appropriate for each situation. For
`instance, if the mobile phone indicates it is busy, the caller
`may hear a message indicating this and be given an oppor-
`tunity to leave a voice message. If the mobile phone indi-
`cates that the call is to be rejected as an undesired call, for
`example, the caller may be given no opportunity to leave a
`message and the call may be immediately terminated.
`Referring to FIG. 4, another embodimentof the invention
`is depicted by call processing flow graph 400.
`In this
`embodiment, the mobile phone user is connected to a current
`call when the incoming call is attempted. Block 402 func-
`tions identically to block 202 of FIG. 2. At block 404, the
`mobile phone user is connected to a current call. The current
`call may become active when the phone goes through the
`stages of call process 200 to reach block 212. At block 212
`the user decides to accept the incoming call which is then
`connected. While processing the connected call, an indica-
`tion of an incoming call arrives as shown at block 406. The
`incoming call
`indication is received at receiver 118 via
`communication channel 124. The incoming call indication
`may contain identification information about the origin of
`the call, such as the caller ID information described above.
`At block 408 a determination in made whether or not to
`
`automatically reject the incoming call. The determination
`can be made when the information about the incoming call
`received at receiver 118 is sent
`to determiner 106 via

`Referring now to FIG. 5, therein is depicted messaging
`sequence 500 which can be used to implement an embodi-
`ment of the present invention as depicted in FIG. 2. Mes-
`saging sequence 500 can be used in a telecommunications
`system operating in accordance with the IS-95 standard.It
`will be apparent to those skilled in the art that by substituting
`the corresponding protocol and processes, the disclosed call
`rejection invention may be similarly implemented using
`different message sequencing as found in other types of
`communications networks.
`
`In the embodiment of FIG. 2, functional blocks 206, 208,
`210, 212, 214, 216, 218 and 220 require messages to be
`transmitted between the mobile phone and the base station
`to fulfill the specified tasks. These messages are sent via
`communication channel 124. The following description,
`which references FIGS. 2 and 5, defines the types of
`messages that are sent, where they originate and what
`portion of communication channel 124 they are transmitted
`on.
