Abstract
A method for picking up a call by a second communication device after the call has been placed on hold by a first communication device regardless of the communication device type or whether it is within a closed network is achieved by detecting, by a server associated with the first communication device, that a call has been placed on hold by the first communication device and subsequently suspending the call. Next, the server associated with the first communication device waits for a directive call pick-up message, which may be provided by the first communication device or from a second communication device directly or via a server associated with the second communication device. When the server associated with the first communication device receives the directive pick-up message, it communicates with the server associated with the second communication device. Such a communication establishes a communication link between the servers such that the call may be picked up by the second communication device.
Description
3 Technical Field of the Invention This invention relates generally to placing an on-going communication on hold 6 and in particular to continuing the on-going corrununication based on a directive call 7 pick-up message.
9 Background of the Invention 11 The basic operation of telephonic communication is known to begin when a 12 calling party places his/her communication device in an "off hook"
condition and dials a 13 telephone number of a called party. The telephone number of the called party is routed to 14 a local server associated with the calling party for processing. Such processing includes determining whether the requested call can be serviced locally by the server, i.e., the 16 called party is associated with the same server as the calling party, or whether the call 17 needs to be routed to a switching network. If the call can be processed locally, the server 18 allocates a line to the calling party and to the called party such that the communication 19 may occur.
21 If the requested communication cannot be serviced locally, the server typically 22 routes the request to an inter-exchange carrier (IEC) which, in turn, routes the request to 23 either another IEC or the local server of the called party and reserves a trunk for the 24 communication. Once the request is routed to the local server of the called party, the local server allocates a line to the called party such that the communication may occur.
27 The above described telephonic communication setup was typical for a voice 28 communication between two wireline telephones occurring twenty years ago, wherein the 29 local servers are local exchange carriers (LEC). Today, the telephonic communication may be for voice, data, video, and/or mufti-media and may be occurring between a ' 31 wireline telephone, a computer, a facsimile machine, a wireless telephone, or a personal 1 agent. In today's telephonic environment, the local servers mentioned above may be 2 LECs, mobile switch centers (MSC), or private branch exchanges (PBX).
4 Not only have the last twenty years produced multiple communication devices and various communication subject matters, it has yielded many user oriented services.
6 Such services include call forwarding, call transferring, multiple party conference calling, 7 call waiting, caller identification, and call hold and pick-up. While these services have 8 greatly enhanced the usefulness of telephonic communications, some may not be useable 9 in a cross platform manner, i.e., by different types of communication devices.
11 In particular, call hold and pick-up only works for wireline communication 12 devices that are associated with the same switch, closed network, or server, and share a 13 line group. Thus, when a first telephone places a call on hold, a second telephone may 14 pick-up the call only if it shares the line group. Alternatively, the first telephone may place a call on hold and transfer it to the second telephone by initiating a call transfer 16 (usually by pressing a transfer button on the phone or entering a code) and then entering 17 the telephone number of the second telephone. In this manner, a call may be placed on 18 hold by one telephone and continued by another.
While the above works for a call hold and pick up for telephones commonly 21 coupled ~to a telephone line, and for call hold and transfer for telephones in a closed 22 network (eg. a network owned or leased by a large, multi-site corporation using a PBX or 23 multiple PBXs), it does not work for different types of communication devices or ones 24 that are outside of the closed network. For example, assume that a person has begun a telephone conversation using his/her wireless telephone (mobile or cellular) in a cellular 26 network and, once the person reaches his/her office or home, would like to transfer the 27 call to a wireline telephone. But, because the wireless telephone is serviced by a server 28 outside the closed network of the office telephone and is different than the home 29 telephone, the person's desire to hold the wireless call and pick-up it up as a wireline call cannot be fulfilled. Currently, the only way the person could fulfill this desire is to end 31 the wireless telephone call and initiate a new wireline telephone call.
2 With the ever increasing use of wireless communication devices, the above 3 scenario is becoming common and some what frustrating to users. Therefore, a need 4 exists for a method that allows for network wide call hold and directive call pick-up S regardless of the type of communication devices involved in the communication.

24 Detailed Description of the Drawings 26 Generally, the present invention provides a method for picking up a call by a 27 second communication device after the call has been placed on hold by a first 28 communication device regardless of the communication device type or whether it is . 29 within a closed network. Such a method may be achieved by detecting, by a server associated with the first communication device, that a call has been placed on hold by the 31 first communication device and subsequently placing the call in a suspended state.
2 Next, the server associated with the first communication device waits for a 3 directive pick-up message, which may be provided by the first communication device or 4 from a second communication device directly or via a server associated with the second communication device. Note that if the directive pick-up message is from the first 6 communication device, it will include a code indicative of the call hold and subsequent 7 pick-up by the second communication device and the identity of the second 8 communication device (eg. the telephone number of the second communication device or 9 a portion thereof). Alternatively note that if the directive pick-up message is from the second communication device it will include a code indicative of the call placed on hold 11 by the first communication device and the identity of the first communication device (eg.
12 the telephone number of the first communication device or a portion thereof).
14 When the server associated with the first communication device receives the IS directive pick-up message, it communicates with the server associated with the second 16 communication device. Such a communication is to establish a communication link 17 between the servers so that the call may be picked up by the second communication 18 device. With such a method, any type of communication may be placed on hold by any 19 type of communication device and continued by any other type of communication device thus providing telecommunication users greater flexibility and enhanced services.
22 The present invention can be more fully described with reference to Figures 1 - 5.
23 Figure 1 illustrates a schematic block diagram of a telecommunication environment 10 24 that includes wireless communication devices 34 48 and wireline communication devices.
The wireless communication device 34 48 may be mobile telephones, cellular telephones, 26 personal agents, wireless modems, a satellite linked cellular telephone, a combination 27 thereof, or any other type of device that transmits and/or receives digitized, packetized, or 28 modulated information via a wireless link. The wireline communication devices may be 29 wireline telephones 22 23 25 27, computers 20 31, facsimile machines 18 29, a combination thereof, or any device that transmits and/or receives digitized, packetized, or 31 modulated information via a wireline link.
2 As shown, the wireless communication devices 34 48 are coupled to a base station 3 32 46 via a wireless link. The base transceiver stations (BTS) 32 44 46, which are 4 coupled to at least one base station controller (BSC), support multiple wireless links (i.e., channels). Of the channels support by a base station, one is typically reserved as a 6 control channel while the remaining channels are allocated upon request to 7 communication devices to support communications. The base station controllers 26 28 8 30 38 40 42 control allocation of the base station channels as well as performing other 9 local area system functions.
11 Each of the base station controllers 26 28 30 38 40 42 is coupled to a mobile 12 switch center (MSC) 24 36, which, in turn, is coupled to a local exchange carrier (LEC) 13 12 16. The mobile switch center 24 36 functions as a server for communication devices 14 associated with it. Communication devices are associated with a server, MSC, as either home devices or visiting devices. Information regarding a home communication device 16 (eg. phone number, device identification code, subscribed to services) are stored in a 17 home location register (HLR) while information regarding a visiting communication 18 device is stored in a visitor location register (VL,R). HLRs, VLRs, BTSs, BSCs, and 19 MCSs are generally understood in the art, thus no further discussion will be presented except to further illustrate the principles of the present invention.
22 As also shown, the wireline telephone 22, the computer 20 and the facsimile 23 machine 18 are coupled to a local exchange carrier (LEC) 12, which is coupled to an 24 inter-exchange carrier (IEC) 14. The wireline telephone 23 is coupled to LEC 16, which is directly or indirectly coupled to IEC 14. The wireline telephones 25 27, the facsimile 26 machine 29 and the computer 31 are coupled to private branch exchange (PBX) 21 which 27 is coupled to LEC 12. The general operation of a wireline telephone, computer, 28 facsimile, and telephone infrastructure is generally understood in the art, thus no further 29 discussion will be presented except to further illustrate the present invention.

24 Detailed Description of the Drawings 26 Generally, the present invention provides a method for picking up a call by a 27 second communication device after the call has been placed on hold by a first 28 communication device regardless of the communication device type or whether it is . 29 within a closed network.

Note that if the directive pick-up message is from the first 6 communication device, it will include a code indicative of the call hold and subsequent 7 pick-up by the second communication device and the identity of the second 8 communication device (eg. the telephone number of the second communication device or 9 a portion thereof). Alternatively note that if the directive pick-up message is from the second communication device it will include a code indicative of the call placed on hold 11 by the first communication device and the identity of the first communication device (eg.
12 the telephone number of the first communication device or a portion thereof).
14 When the server associated with the first communication device receives the IS directive pick-up message, it communicates with the server associated with the second 16 communication device. Such a communication is to establish a communication link 17 between the servers so that the call may be picked up by the second communication 18 device. With such a method, any type of communication may be placed on hold by any 19 type of communication device and continued by any other type of communication device thus providing telecommunication users greater flexibility and enhanced services.
22 The present invention can be more fully described with reference to Figures 1 - 5.
23 Figure 1 illustrates a schematic block diagram of a telecommunication environment 10 24 that includes wireless communication devices 34 48 and wireline communication devices.
The wireless communication device 34 48 may be mobile telephones, cellular telephones, 26 personal agents, wireless modems, a satellite linked cellular telephone, a combination 27 thereof, or any other type of device that transmits and/or receives digitized, packetized, or 28 modulated information via a wireless link. The wireline communication devices may be 29 wireline telephones 22 23 25 27, computers 20 31, facsimile machines 18 29, a combination thereof, or any device that transmits and/or receives digitized, packetized, or 31 modulated information via a wireline link.
2 As shown, the wireless communication devices 34 48 are coupled to a base station 3 32 46 via a wireless link. The base transceiver stations (BTS) 32 44 46, which are 4 coupled to at least one base station controller (BSC), support multiple wireless links (i.e., channels). Of the channels support by a base station, one is typically reserved as a 6 control channel while the remaining channels are allocated upon request to 7 communication devices to support communications. The base station controllers 26 28 8 30 38 40 42 control allocation of the base station channels as well as performing other 9 local area system functions.
11 Each of the base station controllers 26 28 30 38 40 42 is coupled to a mobile 12 switch center (MSC) 24 36, which, in turn, is coupled to a local exchange carrier (LEC) 13 12 16. The mobile switch center 24 36 functions as a server for communication devices 14 associated with it. Communication devices are associated with a server, MSC, as either home devices or visiting devices. Information regarding a home communication device 16 (eg. phone number, device identification code, subscribed to services) are stored in a 17 home location register (HLR) while information regarding a visiting communication 18 device is stored in a visitor location register (VL,R). HLRs, VLRs, BTSs, BSCs, and 19 MCSs are generally understood in the art, thus no further discussion will be presented except to further illustrate the principles of the present invention.
22 As also shown, the wireline telephone 22, the computer 20 and the facsimile 23 machine 18 are coupled to a local exchange carrier (LEC) 12, which is coupled to an 24 inter-exchange carrier (IEC) 14. The wireline telephone 23 is coupled to LEC 16, which is directly or indirectly coupled to IEC 14. The wireline telephones 25 27, the facsimile 26 machine 29 and the computer 31 are coupled to private branch exchange (PBX) 21 which 27 is coupled to LEC 12. The general operation of a wireline telephone, computer, 28 facsimile, and telephone infrastructure is generally understood in the art, thus no further 29 discussion will be presented except to further illustrate the present invention.
1 In the telecommunication environment 10, any one of the communication devices, 2 whether wireless or wireline, may communication with any other communication device.
3 For example, if wireless communication device 34 is a cellular phone, it may participate 4 in a communication with any of the wireline telephones 22 23 25 27 or the computers 20 31, if equipped with telephonic software. Such establishment of a call is generally 6 understood in the art.
3 For example, if wireless communication device 34 is a cellular phone, it may participate 4 in a communication with any of the wireline telephones 22 23 25 27 or the computers 20 31, if equipped with telephonic software. Such establishment of a call is generally 6 understood in the art.
8 While any communication device can communicate with any other 9 communication device, most cannot place a call on hold and have it transferred to another communication device and none can have a call placed on hold and picked up by another 11 communication device unless they share the same telephone line. The only 12 communication devices that can place a call on hold and transfer to another 13 communication device are those coupled to the PBX 21, or similar switch. In such a 14 configuration, the PBX 21 can facilitate a call hold and transfer between only those communication devices that are directly coupled to it. For example, telephone 25 may 16 place a call on hold, press a transfer button or transfer code, enter the telephone number 17 or extension of telephone 27, and provide this information to the PBX 21.
The PBX 21 18 interprets this information and subsequently transfers the call to telephone 27. Note that 19 the PBX 21 may be coupled to other PBXs via LECs and IECs to form a network of PBXs which, for the purposes of this invention, functions as a single PBX.
22 To facilitate a telecommunication environment 10 wide call hold and pick up, the 23 servers within the environment 10 may be programmed to perform the process shown in 24 the logic diagram of Figure 2. The MCSs 24 36, the PBX 21, the LECs 12 16, and the IEC 14 function as servers for the purposes of this invention. But as one skilled in the art 26 will readily appreciate, a dedicate server may be added to the environment, multiple 27 servers may be added, or one of the existing servers may act as a server for the 28 environment or a portion thereof.
The process of Figure 2 begins at step 60 where a server associated with a first 31 communication device detects that the first communication device has placed an on-going communication on hold. As previously mentioned, a communication may be a voice 2 communication, a data communication, a video communication, a mufti-media 3 communication, or a combination thereof and the first communication device would be 4 one capable of supporting such a communication. Note that the first communication S device may place the on-going communication on hold by pressing a hold button or = 6 entering a predetermined hold code.
8 Regardless of how the call was placed on hold, once the server associated with the 9 first communication device detects the hold command, it suspends the communication and waits for information as to where the call is to be directed for a call pick up. This is 11 done at step 62 and the holding of the call may be done in accordance with the IS-41 12 standard. The process then proceeds to step 64 where the server associated with a second 13 communication device receives a request to continue the on-going communication. As 14 one skilled in the art will readily appreciate, the server associated with the first communication device may also be the server associated with the second communication 16 device or they may be two separate servers.
18 The request received by the server associated with the second communication 19 device may be a code entered by the second communication device followed by the identity of the first communication device (eg. the telephone number or a portion thereof 21 of the first communication device). Having received the request, the server associated 22 with the second communication device interprets the request to identify the server 23 associated with the first communication device. Having done this, the servers 24 communicate to allow the second communication device to continue the on-going communication. This is done at step 66.
26 The servers, at step 66, communicate to exchange call routing information and to 27 establish a bridge between the servers. The establishment of the bridge keeps the server 28 associated with the first communication device in the call routing path.
Once the bridge - 29 is established, the process proceeds to step 68 where the second communication device continues the on-going communication.
2 With a method as described in Figure 2, a user of a wireless communication 3 device may place an on-going communication on hold and pick-up, or continue, the 4 communication on a wireline communication device. For example, if the user is using a cellular phone and arrives at his/her office or home and desires to continue a call, the user 6 can place the call on hold, enter a code on his/her wireline phone and the identity of the 7 cellular phone, and continue the call. The same may be done for facsimile transmissions, 8 data transmissions, multi-media transmissions, and video transmissions.
Figure 3 illustrates a logic diagram that may be used by a server associated with a 11 communication device that is placing a call on hold for a subsequent pick-up by another 12 communication device. The process begins at step 70 where the server receives a call 13 hold code from a first communication device and, in response, placing the call on hold.
14 As previously mentioned, this may be done in accordance with the IS-41 standard. The 1 S process then proceeds to step 72 where the server receives a communication from a server 16 associated with a second communication device. The received communication includes a 17 request for the second communication device to continue the on-going communication.
19 The process then proceeds to step 74 where the server establishes a bridge with the server associated with the second communication device. With the bridge in place, 21 the second communication device may continue to the on-going communication.
23 Figure 4 illustrates a logic diagram that may be used by a server associated with a 24 communication device that is attempting to pick-up a call placed on hold by another communication device. The process begins at step 80 where the server receives a request 26 to pick-up an on-going communication from a second communication device.
The 27 request includes a pick-up code and at least the identity of the communication device 28 placing the on-going communication on hold. For example the pick-up code may be *75 29 followed by the last four digits of the communication device's telephone number.
1 The process then proceeds to step 82 where, after interpreting and validating the 2 request, the server associated with the second communication device communicates with 3 the server associated with the first communication device (i.e., the device that placed the 4 call on hold). Such communication would include: providing the identity of the server S associated with the second communication device; providing the identity of the first 6 communication device; providing an indication~that the call is to be picked up by the 7 second communication device; and, may also include, a validation by the server 8 associated with the first communication device that the call pick-up is valid.
Once the communication has been deemed to be successful, the process proceeds 11 to step 84 where a telecommunication bridge is established between the servers. The 12 establishment of bridge between servers is generally understood in the art, thus no further 13 discussion will be presented except to illustrate the present invention.
la Figure 5 illustrates an alternate logic diagram for implementing the present 16 invention wherein a directive pick-up message may be initiated by either the first 17 communication device or the second communication device. The process begins at step 18 90 where a server determines whether it has received a call hold message.
If not, the 19 process proceeds to step 92 where the server determines whether it has received a directive call pick-up message. If not, the process remains in a loop waiting for either a 21 call hold message or a directive pick-up message.
23 When a call hold message is received, the process proceeds to step 94 where the 24 server suspends an on-going communication identified by the call hold message. The process then proceeds to step 96 where the server waits to receive a directive pick-up 26 message. The directive pick-up message may be provided by the server associated with a 27 second communication device (i.e., the device picking up the call) and will include an 28 indication of the call pick up and the identity of the first communication device (i.e., the 29 device placing the call on hold). If a directive call pick up message is not received within a time out period, step 98, the process returns to step 90.
2 When the directive pick up message is received from the second communication 3 device, the process proceeds to step 100 where the server associated with the first 4 communication device communicates with the server associated with the second communication device to establish a bridge between the two servers. With the bridge in 6 place, the process proceeds to step 102 where tl;e on-going communication is continued 7 by the second communication unit.
9 As one skilled in the art will readily appreciate, the directive pick-up message may also come from the first communication device. When this occurs, the on-going 11 communication would not be suspended until after the call hold message and the directive 12 pick-up message are received. In this scenario, the server associated with the first 13 communication device would identify the server associated with the second 14 communication device and initiate the communication to establish the bridge between the two servers.
17 When a directive pick-up message is received prior to a call hold message, which 18 may occur when the user initiates the call pick-up before initiating the call hold, the 19 process proceeds to step 104. At this step, the server stores the directive pick-up message then proceeds to step 106 to await the receipt of a call hold message. If a time out period 2I expires, step 108, prior to receiving a call hold message, the process returns to step 90. If, 22 however, the call hold message is received prior to the time out period, the process 23 proceeds to step 100.
24 As the preceding discussion has demonstrated, the present invention provides a method for continuing a communication regardless of the types of communication 26 devices being used. Thus, as an example, the present invention provides the user of a 27 wireless communication device the ability to place an on-going communication on hold 28 and continuing the communication using a wireline communication device.
This is 29 achievable whether the communication is voice, data, facsimile, video, mufti-media or any other type of digitized, packetized, or modulated information.
The PBX 21 18 interprets this information and subsequently transfers the call to telephone 27. Note that 19 the PBX 21 may be coupled to other PBXs via LECs and IECs to form a network of PBXs which, for the purposes of this invention, functions as a single PBX.
22 To facilitate a telecommunication environment 10 wide call hold and pick up, the 23 servers within the environment 10 may be programmed to perform the process shown in 24 the logic diagram of Figure 2. The MCSs 24 36, the PBX 21, the LECs 12 16, and the IEC 14 function as servers for the purposes of this invention. But as one skilled in the art 26 will readily appreciate, a dedicate server may be added to the environment, multiple 27 servers may be added, or one of the existing servers may act as a server for the 28 environment or a portion thereof.
The process of Figure 2 begins at step 60 where a server associated with a first 31 communication device detects that the first communication device has placed an on-going communication on hold. As previously mentioned, a communication may be a voice 2 communication, a data communication, a video communication, a mufti-media 3 communication, or a combination thereof and the first communication device would be 4 one capable of supporting such a communication. Note that the first communication S device may place the on-going communication on hold by pressing a hold button or = 6 entering a predetermined hold code.
8 Regardless of how the call was placed on hold, once the server associated with the 9 first communication device detects the hold command, it suspends the communication and waits for information as to where the call is to be directed for a call pick up. This is 11 done at step 62 and the holding of the call may be done in accordance with the IS-41 12 standard. The process then proceeds to step 64 where the server associated with a second 13 communication device receives a request to continue the on-going communication. As 14 one skilled in the art will readily appreciate, the server associated with the first communication device may also be the server associated with the second communication 16 device or they may be two separate servers.
18 The request received by the server associated with the second communication 19 device may be a code entered by the second communication device followed by the identity of the first communication device (eg. the telephone number or a portion thereof 21 of the first communication device). Having received the request, the server associated 22 with the second communication device interprets the request to identify the server 23 associated with the first communication device. Having done this, the servers 24 communicate to allow the second communication device to continue the on-going communication. This is done at step 66.
26 The servers, at step 66, communicate to exchange call routing information and to 27 establish a bridge between the servers. The establishment of the bridge keeps the server 28 associated with the first communication device in the call routing path.
Once the bridge - 29 is established, the process proceeds to step 68 where the second communication device continues the on-going communication.
2 With a method as described in Figure 2, a user of a wireless communication 3 device may place an on-going communication on hold and pick-up, or continue, the 4 communication on a wireline communication device. For example, if the user is using a cellular phone and arrives at his/her office or home and desires to continue a call, the user 6 can place the call on hold, enter a code on his/her wireline phone and the identity of the 7 cellular phone, and continue the call. The same may be done for facsimile transmissions, 8 data transmissions, multi-media transmissions, and video transmissions.
Figure 3 illustrates a logic diagram that may be used by a server associated with a 11 communication device that is placing a call on hold for a subsequent pick-up by another 12 communication device. The process begins at step 70 where the server receives a call 13 hold code from a first communication device and, in response, placing the call on hold.
14 As previously mentioned, this may be done in accordance with the IS-41 standard. The 1 S process then proceeds to step 72 where the server receives a communication from a server 16 associated with a second communication device. The received communication includes a 17 request for the second communication device to continue the on-going communication.
19 The process then proceeds to step 74 where the server establishes a bridge with the server associated with the second communication device. With the bridge in place, 21 the second communication device may continue to the on-going communication.
23 Figure 4 illustrates a logic diagram that may be used by a server associated with a 24 communication device that is attempting to pick-up a call placed on hold by another communication device. The process begins at step 80 where the server receives a request 26 to pick-up an on-going communication from a second communication device.
The 27 request includes a pick-up code and at least the identity of the communication device 28 placing the on-going communication on hold. For example the pick-up code may be *75 29 followed by the last four digits of the communication device's telephone number.
1 The process then proceeds to step 82 where, after interpreting and validating the 2 request, the server associated with the second communication device communicates with 3 the server associated with the first communication device (i.e., the device that placed the 4 call on hold). Such communication would include: providing the identity of the server S associated with the second communication device; providing the identity of the first 6 communication device; providing an indication~that the call is to be picked up by the 7 second communication device; and, may also include, a validation by the server 8 associated with the first communication device that the call pick-up is valid.
Once the communication has been deemed to be successful, the process proceeds 11 to step 84 where a telecommunication bridge is established between the servers. The 12 establishment of bridge between servers is generally understood in the art, thus no further 13 discussion will be presented except to illustrate the present invention.
la Figure 5 illustrates an alternate logic diagram for implementing the present 16 invention wherein a directive pick-up message may be initiated by either the first 17 communication device or the second communication device. The process begins at step 18 90 where a server determines whether it has received a call hold message.
If not, the 19 process proceeds to step 92 where the server determines whether it has received a directive call pick-up message. If not, the process remains in a loop waiting for either a 21 call hold message or a directive pick-up message.
23 When a call hold message is received, the process proceeds to step 94 where the 24 server suspends an on-going communication identified by the call hold message. The process then proceeds to step 96 where the server waits to receive a directive pick-up 26 message. The directive pick-up message may be provided by the server associated with a 27 second communication device (i.e., the device picking up the call) and will include an 28 indication of the call pick up and the identity of the first communication device (i.e., the 29 device placing the call on hold). If a directive call pick up message is not received within a time out period, step 98, the process returns to step 90.
2 When the directive pick up message is received from the second communication 3 device, the process proceeds to step 100 where the server associated with the first 4 communication device communicates with the server associated with the second communication device to establish a bridge between the two servers. With the bridge in 6 place, the process proceeds to step 102 where tl;e on-going communication is continued 7 by the second communication unit.
9 As one skilled in the art will readily appreciate, the directive pick-up message may also come from the first communication device. When this occurs, the on-going 11 communication would not be suspended until after the call hold message and the directive 12 pick-up message are received. In this scenario, the server associated with the first 13 communication device would identify the server associated with the second 14 communication device and initiate the communication to establish the bridge between the two servers.
17 When a directive pick-up message is received prior to a call hold message, which 18 may occur when the user initiates the call pick-up before initiating the call hold, the 19 process proceeds to step 104. At this step, the server stores the directive pick-up message then proceeds to step 106 to await the receipt of a call hold message. If a time out period 2I expires, step 108, prior to receiving a call hold message, the process returns to step 90. If, 22 however, the call hold message is received prior to the time out period, the process 23 proceeds to step 100.
24 As the preceding discussion has demonstrated, the present invention provides a method for continuing a communication regardless of the types of communication 26 devices being used. Thus, as an example, the present invention provides the user of a 27 wireless communication device the ability to place an on-going communication on hold 28 and continuing the communication using a wireline communication device.
This is 29 achievable whether the communication is voice, data, facsimile, video, mufti-media or any other type of digitized, packetized, or modulated information.
