`
`FIELD OF THE INVENTION
`
`[0002]
`
`The present invention relates to systems and methods for setting up and
`
`connecting telephone calls, and delivering information related to such telephonecalls
`
`using an Internet Protocol (IP) or other data channel while delivering the voice portion of
`
`the call in accordance with CDMA, GSM or like voice channel delivery standards.
`
`BACKGROUND OF THE INVENTION
`
`[0003]
`
`The volume of telephone calls and text messaging has increased dramatically
`
`and users are finding it more and more difficult to manage that volume of calls and
`
`15
`
`messages. The current systemsto aid in managing some typesof calls only provide
`
`minimal assistance to the user.
`
`It
`
`is therefore an advantage of some, but not
`
`necessarily all, embodiments of the present invention to provide systems and methods
`
`for assisting callers and call recipients with the managementof calls and messages.
`
`[0004]
`
`Additional advantages of various embodiments of the invention are setforth,
`
`20
`
`in part, in the description that follows and, in part, will be apparent to one of ordinary
`
`skill in the art from the description and/or from the practice of the invention.
`
`SUMMARYOF THE INVENTION
`
`[0005]
`
`Responsive to the foregoing challenges, Applicant has developed an
`
`innovative method of providing telephone service by transmitting call handling
`
`29
`
`information between a handset and a switch using an IP channel or similar protocol
`
`channel and by transmitting a voice call associated with the call handling information
`
`between the handsetand the switch using a voice channel provided in accordance with
`
`a voice channel protocol, é.g., in accordance with CDMA or GSM, 3G, 4G, LTE or like
`
`future protocol channels standards.
`

`
`communications according to CDMA, GSM, or like standards. Such IP governed
`
`communications are referred to herein as being conducted over a “data channel.”
`
`Conversely, communications between the switch 110 and the handset over the PSTN
`
`310 may be transmitted and received in accordance with CDMA, GSM or like standards
`
`as opposed to using IP. Such CDMA, GSM or like governed communications, when
`
`used to carry voice information, are referred to herein as being conducted overa “voice
`
`channel.”
`
`[0022] With reference to Figs. 1 and 2, method embodiments of the invention may
`
`be facilitated starting with step 200 in which a handset 340 may be used to subscribeto
`
`10
`
`the telephone network that includes the server 100 and switch 110 used to provide
`
`telephone service in accordance with embodiments of the invention. A user may
`
`subscribe to the telephone network in step 200 by enrolling the telephone handset 340
`
`using a data channel connection between the handset and the server 100. Responsive
`
`to a data channel request received from the handset 340, a handset application may be
`
`15
`
`transmitted to the handset from the server 100, and installed and stored in memory
`
`associated with the handset in step 202. Once the handsetapplication is installed on
`
`the handset 340, the handset may connect to the server 100 by operation of the
`
`handset application as needed over a data channel connection which mayinclude the
`
`BS 328, RNC 326 or PCU 327, SGSN 324, GGSN 322, and Internet 316.
`
`20
`
`[0023]
`
`In connection with step 204, the server 100 may transmit information to the
`
`handset 340 via the data channel, which, through automatic operation of the handset
`
`
`
`
`application,permitstheusertoselectoneormoresecondarytelephonenumberstobe
`
`
`
`
`referencedtoaprimarynumberforthehandset.telephone The primary telephone
`
`number, preferably, may be a SIM number or ESN which is assigned to the handset
`
`25
`
`340 at the time of activation. Once selected, the handset 340 may automatically
`
`transmit information which to the server 100 over the data channel which requests that
`
`the secondary telephone numbers be associated with the primary telephone number.
`
`In
`
`response,
`
`the server 100 may store (i.e.,
`
`reference)
`
`information indicating the
`
`association of the one or more selected secondary telephone numbers in computer
`
`30
`
`memory associated with the server such as the database 120.
`
`In an alternative
`
`embodiment,
`
`the server 100 may automatically assign one or more secondary
`
`telephone numbers to the handset 340, as opposed to them being selected.
`
`[0024]
`
`In step 206 of Fig. 2, the handset 340 may be used to access the handset
