Definitions

  • This invention relates generally to placing an on-going communication on hold and in particular to continuing the on-going communication based on a directive call pick-up message.
  • the basic operation of telephonic communication is known to begin when a calling party places his/her communication device in an "off hook" condition and dials a telephone number of a called party.
  • the telephone number of the called party is routed to a local server associated with the calling party for processing.
  • processing includes determining whether the requested call can be serviced locally by the server, i.e., the called party is associated with the same server as the calling party, or whether the call needs to be routed to a switching network. If the call can be processed locally, the server allocates a line to the calling party and to the called party such that the communication may occur.
  • the server typically routes the request to an inter-exchange carrier (IEC) which, in turn, routes the request to either another IEC or the local server of the called party and reserves a trunk for the communication.
  • IEC inter-exchange carrier
  • the local server allocates a line to the called party such that the communication may occur.
  • the above described telephonic communication setup was typical for a voice communication between two wireline telephones occurring twenty years ago, wherein the local servers are local exchange carriers (LEC).
  • LEC local exchange carriers
  • the telephonic communication may be for voice, data, video, and/or multi-media and may be occurring between a wireline telephone, a computer, a facsimile machine, a wireless telephone, or a personal agent.
  • the local servers mentioned above may be LECs, mobile switch centers (MSC), or private branch exchanges (PBX).
  • Such services include call forwarding, call transferring, multiple party conference calling, call waiting, caller identification, and call hold and pick-up. While these services have greatly enhanced the usefulness of telephonic communications, some may not be useable in a cross platform manner, i.e., by different types of communication devices.
  • call hold and pick-up only works for wireline communication devices that are associated with the same switch, closed network, or server, and share a line group.
  • a second telephone may pick-up the call only if it shares the line group.
  • the first telephone may place a call on hold and transfer it to the second telephone by initiating a call transfer (usually by pressing a transfer button on the phone or entering a code) and then entering the telephone number of the second telephone. In this manner, a call may be placed on hold by one telephone and continued by another.
  • a closed network eg. a network owned or leased by a large, multi-site corporation using a PBX or multiple PBXs
  • Figure 1 illustrates a schematic block diagram of a telecommunication environment in which the present invention may be practiced
  • Figure 2 illustrates a logic diagram that may be used to implement the present invention
  • Figure 3 illustrates a logic diagram that may be used by a switch to implement the present invention
  • Figure 4 illustrates an alternate logic diagram that may be used by a switch to implement the present invention.
  • Figure 5 illustrates an alternate logic diagram that may be used to implement the present invention.
  • the present invention provides 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.
  • 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 first communication device and subsequently placing the call in a suspended state.
  • the server associated with the first communication device waits for a directive 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.
  • the directive pick-up message is from the first communication device, it will include a code indicative of the call hold and subsequent pick-up by the second communication device and the identity of the second communication device (eg. the telephone number of the second communication device or a portion thereof).
  • the directive pick-up message is from the second communication device it will include a code indicative of the call placed on hold by the first communication device and the identity of the first communication device (eg. the telephone number of the first communication device or a portion thereof).
  • the server associated with the first 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 is to establish a communication link between the servers so that the call may be picked up by the second communication device. With such a method, any type of communication may be placed on hold by any type of communication device and continued by any other type of communication device thus providing telecommunication users greater flexibility and enhanced services.
  • Figure 1 illustrates a schematic block diagram of a telecommunication environment 10 that includes wireless communication devices 34 48 and wireline communication devices.
  • the wireless communication device 34 48 may be mobile telephones, cellular telephones, personal agents, wireless modems, a satellite linked cellular telephone, a combination thereof, or any other type of device that transmits and/or receives digitized, packetized, or modulated information via a wireless link.
  • the wireline communication devices may be 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 modulated information via a wireline link.
  • the wireless communication devices 3448 are coupled to a base station 32 46 via a wireless link.
  • the base transceiver stations (BTS) 32 44 46 which are 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 control channel while the remaining channels are allocated upon request to communication devices to support communications.
  • the base station controllers 26 28 30 38 40 42 control allocation of the base station channels as well as performing other local area system functions.
  • Each of the base station controllers 26 28 30 38 40 42 is coupled to a mobile switch center (MSC) 24 36, which, in turn, is coupled to a local exchange carrier (LEC) 12 16.
  • the mobile switch center 24 36 functions as a server for communication devices associated with it. Communication devices are associated with a server, MSC, as either home devices or visiting devices. Information regarding a home communication device (eg. phone number, device identification code, subscribed to services) are stored in a home location register (HLR) while information regarding a visiting communication device is stored in a visitor location register (VLR). HLRs, VLRs, BTSs, BSCs, and MCSs are generally understood in the art, thus no further discussion will be presented except to further illustrate the principles of the present invention.

  • any communication device can communicate with any other 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 communication device unless they share the same telephone line.
  • the only communication devices that can place a call on hold and transfer to another communication device are those coupled to the PBX 21, or similar switch.
  • the PBX 21 can facilitate a call hold and transfer between only those communication devices that are directly coupled to it.
  • telephone 25 may place a call on hold, press a transfer button or transfer code, enter the telephone number or extension of telephone 27, and provide this information to the PBX 21.
  • the PBX 21 interprets this information and subsequently transfers the call to telephone 27.
  • 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.
  • the servers within the environment 10 may be programmed to perform the process shown in 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.
  • a dedicate server may be added to the environment, multiple servers may be added, or one of the existing servers may act as a server for the environment or a portion thereof.

  • a communication may be a voice communication, a data communication, a video communication, a multi-media communication, or a combination thereof and the first communication device would be one capable of supporting such a communication.
  • the first communication device may place the on-going communication on hold by pressing a hold button or entering a predetermined hold code.
  • the server associated with the 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 done at step 62 and the holding of the call may be done in accordance with the IS-41 standard. The process then proceeds to step 64 where the server associated with a second communication device receives a request to continue the on-going communication.
  • the server associated with the first communication device may also be the server associated with the second communication device or they may be two separate servers.
  • the request received by the server associated with the second communication 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 of the first communication device). Having received the request, the server associated with the second communication device interprets the request to identify the server associated with the first communication device. Having done this, the servers communicate to allow the second communication device to continue the on-going communication. This is done at step 66.
  • the servers, at step 66 communicate to exchange call routing information and to establish a bridge between the servers. The establishment of the bridge keeps the server associated with the first communication device in the call routing path. Once the bridge is established, the process proceeds to step 68 where the second communication device continues the on-going communication.
  • a user of a wireless communication device may place an on-going communication on hold and pick-up, or continue, the communication on a wireline communication device.

The same may be done for facsimile transmissions, data transmissions, multi-media transmissions, and video transmissions.
  • Figure 3 illustrates a logic diagram that may be used by a server associated with a communication device that is placing a call on hold for a subsequent pick-up by another communication device.
  • the process begins at step 70 where the server receives a call hold code from a first communication device and, in response, placing the call on hold. As previously mentioned, this may be done in accordance with the IS-41 standard.
  • the process then proceeds to step 72 where the server receives a communication from a server associated with a second communication device.
  • the received communication includes a request for the second communication device to continue the on-going communication.
  • step 74 the server establishes a bridge with the server associated with the second communication device. With the bridge in place, the second communication device may continue to the on-going communication.

Abstract

L'invention porte sur un procédé de prise d'appel par un second dispositif de communication après mise en garde de l'appel par un premier dispositif de communication sans tenir compte du type du dispositif de communication ou si celui-ci se trouve dans un réseau fermé. Ce procédé consiste à détecter, par un serveur associé au premier dispositif de communication, la mise en garde d'un appel effectuée par le premier dispositif de communication et à suspendre ensuite l'appel. Puis, le serveur associé au premier dispositif de communication attend un message de prise d'appel directif qui peut être envoyé par le premier dispositif de communication ou provenir directement d'un second dispositif de communication ou être envoyé par l'intermédiaire d'un serveur associé au second dispositif de communication. Lorsque le serveur associé au premier dispositif de communication reçoit le message de prise d'appel directif, il le communique au serveur associé au second dispositif de communication. Cette communication établit une liaison entre les serveurs de sorte que l'appel puisse être pris par le second dispositif de communication.
