1. Mobile computing device registration in home network

This Section will describe the steps that are performed, when a mobile computing device to the service node <figref>130</figref> in home network the mobile computing device registered. A home network is defined as the Netw ork, with the mobile computing device most frequently connected is. When connected to the home network, using a mobile computing device their permanent IP address, stored in the memory the mobile computing device is stored. <figref idrefs="S40">2</figref> is a message flow diagram illustrating the percolated News shows when a mobile computing device at the service node <figref>130</figref> on the home network of the mobile computer device registered. It it is assumed that the mobile computing device <figref>104</figref> with the LAN <figref>140</figref> as in <figref idrefs="S39">1</figref> is shown connected, and that the mobile computing device <figref>104</figref> at the service node <figref>130</figref> registered is. As in<figref idrefs="S40">2</figref> shown is the first message <figref>202</figref> a Registration Notification (REGNOT) from the mobile computing device <figref>104</figref> to the service node <figref>130</figref>, The REGNOT message<figref>202</figref> includes the permanent IP address of the mobile computing device <figref>104</figref>,

It It should be noted that the database <figref>164</figref> the service node <figref>130</figref> on Profile for includes any mobile computer device to authorize Connection to the data network <figref>102</figref> Has. This profile includes the permanent IP address of the mobile computing device, if the device the data network <figref>102</figref> as its Home network has. If the service node<figref>130</figref> therefore, the IP address the mobile computing device <figref>104</figref> in the message <figref>202</figref> receives, recognizes the service node <figref>130</figref> the mobile computing device <figref>104</figref> and allowed its registration. If desired, could the REGNOT message<figref>202</figref> also include a password that service node to the <figref>130</figref> known would. at such an implementation would be the correct password is required before the service node <figref>130</figref> the mobile computing device registered. After receiving the message REGNOT<figref>202</figref> stores the service node <figref>130</figref> Information in the database <figref>164</figref>. indicating that the mobile computing device <figref>104</figref> registered is. The service node then sends a confirmation message (Ack)<figref>204</figref> at the mobile computing device <figref>104</figref>, Confirming that the mobile computing device <figref>104</figref> registered with the service node is.

Of the Registration procedure could be initiated in any number of ways. For example could registration by a user of a mobile action Computing device be initiated, for example. A mouse click on an appropriate area on the screen. Alternatively registration with the service node <figref>130</figref> automatically always then executed when your computer is turned on and connected to the data network connected is.

2. Registration the network of a visiting mobile computing device

<figref idrefs="S40">3</figref> is a message flow diagram illustrating the percolated News shows when a visiting mobile computing device with the service node <figref>130</figref> registered is. Assume that visiting mobile computing device<figref>107</figref> With the LAN <figref>142</figref> is connected, but the LAN <figref>142</figref> not the home LAN to the mobile computing device <figref>107</figref> connected is. Therefore, the mobile computing device<figref>107</figref> not use their permanent IP address, while the LAN <figref>142</figref> connected , since this IP address from the LAN <figref>142</figref> not Recognised will be. To register, send the mobile computing device<figref>107</figref> a registration request (RegReq) message <figref>302</figref> at rout <figref>122</figref> in LAN <figref>142</figref>, The RegReq message includes an identification of the mobile computing device <figref>107</figref>, The router can run an application that as a Dynamic Host Configuration Process is called, the message RegReq <figref>302</figref> receives the the identification of the mobile computing device <figref>107</figref> and having a temporary IP-address of the mobile computing device <figref>107</figref> assigns. The temporary IP address will only be used while the mobile computing device <figref>107</figref> in the LAN <figref>142</figref> registered remains. The router<figref>122</figref> in the LAN <figref>142</figref> returns the temporary IP address back to the mobile computing device <figref>107</figref> in the message <figref>304</figref>, Upon receipt of the temporary IP address sends the mobile computing device <figref>107</figref> a REGNOT message <figref>306</figref> the emergency message <figref>306</figref> at the service node <figref>130</figref>, The Reg-emergency message<figref>306</figref> includes temporary IP address and an identification at the mobile computing device <figref>107</figref>,

At the Receiving the REGNOT message <figref>306</figref> checked the service node <figref>130</figref> the in the message <figref>306</figref> received ID against his List of authorized devices to determine whether the mobile computing device <figref>107</figref> is registered. If the mobile computing device <figref>107</figref> is authorized spei&lt;?page 6?&gt;chert then the service node <figref>130</figref> Information in the database <figref>164</figref>. indicating that the mobile computing device <figref>107</figref> registered is. The service node<figref>130</figref> then sends a confirmation (Ack) message <figref>308</figref> at the mobile computing device <figref>107</figref> and confirmed that the mobile computing device <figref>107</figref> the service node <figref>130</figref> registered is.

3. Mobile Computer device deregistration

Around a mobile computing device with the service node <figref>130</figref> to deregister or log, transmits the mobile Computing device, a de-register message to the service node <figref>130</figref>, The service node will then update its database to indicate the mobile computing device is not registered any longer.

the deregistration could be initiated in a variety of ways. For example, the Registration by a user of the mobile computing device action be initiated, for example. By clicking on an appropriate area on the Screen. Alternatively the Deregistrie tion with the service node <figref>130</figref> automatically be executed whenever the computer is turned off.

Further could deregistration be initiated, if the mobile computing device for a predetermined Time duration has been idle. In this case, the deregistration could in be a screensaver bound, so that if the screen saver is activated, the deregistration is initiated. Furthermore, could the New registration be initiated automatically when the screen saver is disabled (eg. when a user performs an activity).

4. Data network call between registered mobile computing devices

<figref idrefs="S40">4</figref> is a message flow diagram, the message processing and the shows the run , when a mobile computing device on a data network <figref>102</figref> a Voice call to another mobile computing device on the data network <figref>102</figref> settles. It is assumed that the mobile computing device <figref>104</figref> a voice call to a mobile computing device <figref>106</figref> wants you to stop. It Also assume that both mobile computing device <figref>104</figref> as well as the mobile computing device <figref>106</figref> the service node <figref>130</figref> registered are.

Around to initiate the call, sends the mobile computing device <figref>104</figref> a Originating request (OrigReq) message <figref>402</figref> a service node <figref>130</figref>, The OrigReq message <figref>402</figref> includes an identification of the calling mobile computing device <figref>104</figref>, An ID the called mobile computing device <figref>106</figref> and the Type of call (eg. Language). The identification of the mobile Computing device, the IP address or may be a different its identification, the service node <figref>130</figref> as with linked a particular mobile computing device detects. Upon receiving the message OrigReq <figref>402</figref> checked the service node <figref>130</figref> the Status of the called device in step <figref>403</figref>, To the To check status, leads the service node <figref>130</figref> a database <figref>164</figref> Query, to determine whether the called mobile computing device when service node <figref>130</figref> is registered. In this case, the service node <figref>130</figref> determine that the mobile computing device <figref>106</figref> at the service node <figref>130</figref> is registered and the service node <figref>130</figref> becomes an alarm message <figref>404</figref> to the mobile computing device <figref>106</figref> send. The alarm could an audio and / or visual display on the mobile computing device <figref>106</figref> cause an incoming call to the device exists. Furthermore, could the Alarm also an identification of the calling party or device . include Here is building the service node<figref>130</figref> a through connection (Ie voice path) <figref>410</figref> between the mobile computing device <figref>104</figref> and the mobile computing device <figref>106</figref> on by the call from the mobile computing device <figref>104</figref> to the mobile computing device <figref>106</figref> connected is. This is achieved by the IP addresses of the devices be used. It is assumed that the user of the mobile computing device <figref>106</figref> wishes to answer the call. The user performs an appropriate function (eg., a mouse click) on the mobile computing device <figref>106</figref> out, the mobile computing device <figref>106</figref> to bring a reply message <figref>406</figref> to the service node <figref>130</figref> to send. Upon receipt of the response message<figref>406</figref> updated the service node <figref>130</figref> the status of the mobile computing devices <figref>104</figref> and <figref>106</figref>. to indicate that they are involved in a call. The mobile computing device <figref>106</figref> and the mobile computing device <figref>104</figref> can about the speech path <figref>410</figref> communicate.

It it should be noted that the mobile computer devices transmit voice information, by IP over LAN <figref>140</figref> is used, which is a packet network. As such must the mobile computing devices corresponding software and hardware included so that they are participating in a voice call over the IP network can. The transfer voice calls over an IP network is well known in the art. For example VoxPhone^T^M Pro 3.0 a of E-Tech Canada Limited available Product. VoxPhone^T^M is an IP telephony-based PC application that call functions between performs mobile computing devices.

Of the service node <figref>130</figref> monitors the progress of the call between the mobile Rechnervor&lt;?page 7?&gt;direction <figref>104</figref> and the mobile computing device <figref>106</figref>, The service node<figref>130</figref> is able to monitor the call, as it the status of participating in the call mobile computing devices <figref>104</figref>. <figref>106</figref> knows. If the status changes of a mobile computing device, is the updated information regarding the new status to the service node <figref>130</figref> sent from the mobile computing device via IP. While the call is in progress, if another call for the mobile computing devices is received, therefore, the service node <figref>130</figref> knowledge, that the mobile computing device currently engaged in a call is. In such a situation, the mobile computing device could Show that another call was received (similar to the Call Waiting) or the Neuanrufende could be informed that the called mobile computing device is busy and the new callers could leave a message in a voice mail system. Since the service node<figref>130</figref> further monitors the call, could the service node <figref>130</figref> provide other services, as conference calls, three-way calling, call forwarding, checking incoming Calls restriction outgoing calls, short message service (SMS text-to-phone) an indicator of Message Waiting (MWI) and information services (eg. Stock quotes, Meeting reminder, etc.).

5. Data network call from a registered mobile computer device to not a registered mobile computer device

<figref idrefs="S41">5</figref> is a message flow diagram, the message processing and the shows the run , when a mobile computing device in the data network <figref>102</figref> a Voice call to an unregistered mobile computer device in the data network <figref>102</figref> settles. It is assumed that the mobile computing device <figref>104</figref> a voice call to a mobile computing device <figref>106</figref> wants you to stop. Also Assume that the mobile computing device <figref>104</figref> at the service node <figref>130</figref> is registered but the mobile computing device <figref>106</figref> at the service node <figref>130</figref> is not registered.

Around to initiate the call, sends the mobile computing device <figref>104</figref> a Originating request (OrigReq) message <figref>502</figref> to the service node <figref>130</figref>, The OrigReq message <figref>502</figref> is the same message as message <figref>402</figref>That in connection with <figref idrefs="S40">4</figref> described has been. Upon receiving the message OrigReq <figref>502</figref> checked the service node <figref>130</figref> the Status of the called device in step <figref>504</figref>by a database <figref>164</figref> Query is performed to determine whether the called mobile computing device <figref>106</figref> the service node <figref>130</figref> registered is. In this case, the service node is<figref>130</figref> recognize, the mobile computing device <figref>106</figref> the service node <figref>130</figref> not is registered. The service node<figref>130</figref> will then try the call from the mobile computing device <figref>104</figref> to a to connect cordless phone with the mobile computing device <figref>106</figref> is linked, as follows: The service node <figref>130</figref> maintains a database <figref>164</figref> query from, to detect a mobile identification number (MIN), the with the mobile computing device <figref>106</figref> is linked. As described above, stores the service node <figref>130</figref> Information, the each mobile computing device is concerned, that is authorized Service from the Service Node <figref>130</figref> to obtain. In this Information is a MIN associated with the mobile computing device connected is. As is well known in wireless communications, each MIN addition associated with a particular HLR. A range of MINs will be linked to a particular HLR. The service node <figref>130</figref> stores a lookup table in the database <figref>164</figref>, the MINs linked to its HLR. Thus leads the service node <figref>130</figref> in determining the MIN another Database <figref>164</figref> Query to the application associated with MIN HLR to determine. In determining the MIN and associated HLR sends the service node <figref>130</figref> a location request (LOCREQ) message <figref>506</figref> at the HLR <figref>134</figref> in the wireless communication network. the Locreq message <figref>506</figref> includes the MIN.

The HLR <figref>134</figref> stores a profile for each MIN associated with the HLR <figref>134</figref> is linked. This profile includes a flag, if the wireless phone with the corresponding MIN is registered with the wireless network, and if this is the case, the identification of the current serving MSC. Upon receipt of the message<figref>506</figref> therefore determines the HLR <figref>134</figref> the currently serving MSC and sends a route request (RouteReq) message <figref>508</figref> at this serving MSC. The serving MSC assigns the receipt of the message<figref>508</figref> a Temporary Location Directory Number (TLDN) for the call to the wireless telephone that is associated with the MIN. The operation of the MSC are the assigned TLDN to the HLR <figref>134</figref> in the RouteReq message <figref>510</figref> back. The HLR<figref>134</figref> then transfers the TLDN to the service node <figref>130</figref> in locreq message <figref>512</figref>,

It It should be noted that the messages <figref>506</figref>. <figref>508</figref>. <figref>510</figref>. <figref>512</figref> IS-41 Headlines. IS-41 is a telecommunications standard protocol, the message to support Mobility Management provides. IS-41 is described in further detail in TIA / EIA / IS-41 Cellular Radio Telecommunications Intersystem Operations, Revision C described.

6. Call to a data network computing device of a device from outside when the computing device is registered

<figref idrefs="S42">6</figref> is a message flow diagram, the message processing and the indicating the run is when a telephone from outside a call to a phone number settles that with a mobile linked computing device is and the mobile computing device to the service node <figref>130</figref> registered is. It should be noted that this phone number with the mobile A computing device and / or a wireless phone could be linked. For this For example, it is assumed that the telephone number from the phone outside chosen was a MIN associated with a wireless telephone in the wireless Telephone network is linked. However, if the user of the telephone that is associated with the MIN, also a user of the data network <figref>102</figref> and the service node <figref>103</figref>. could then the user settle all calls to the MIN, the first with the mobile computing device the user is connected, if the user's mobile computing device with the service node <figref>130</figref> registered is. Such a process is running as follows.

It Assume that a telephone outside of a call to a MIN is deposited, which is associated with a wireless telephone of a user. The call is to the home MSC <figref>136</figref> Wireless telephone routed. As with the standard wireless telephone call processing sends the MSC <figref>136</figref> a locreq message <figref>602</figref> including selected MIN to HLR <figref>134</figref>To the current location of the wireless Phone to determine. However, since the user of the wireless telephone also a user of the data network <figref>102</figref> and the service node <figref>130</figref> is, the user has a user profile in the HLR <figref>134</figref> built up, to indicate that any calls to the MIN first through the Data network <figref>102</figref> is to be connected. Upon receipt of the message<figref>602</figref> sends the HLR <figref>134</figref> a service request message <figref>604</figref> including MIN and the type of the service node <figref>130</figref>, Upon receiving the Service request message <figref>604</figref> performs the service node <figref>130</figref> a Database <figref>164</figref> Query to resolve the identification of the mobile to determine computing device that is associated with the received MIN. Such identification is advantageously the IP address be the mobile computing device. In determining the associated mobile computing device checks the Service Node <figref>130</figref> the status the mobile computing device in step <figref>606</figref> by performing Database <figref>164</figref> Query, to determine whether the called mobile computing device with the service node <figref>130</figref> registered is. If this is the case, the service node is<figref>130</figref> determine, the mobile computing device 106 to the service node <figref>130</figref> registered is.

Of the service node <figref>130</figref> is then a TLDN from a pool of TLDNs choose the associated with the service node are, and will be the TLDN to the HLR in the service request message <figref>608</figref> send. Upon receipt of the TLDN, the HLR sends the TLDN to the MSC <figref>136</figref> in the locreq message <figref>610</figref>, Upon receipt of the TLDN sets the MSC <figref>136</figref> a call from the TLDN by an ISUP message <figref>612</figref> used is, and the call is to the service node <figref>130</figref> passed. Upon receiving the call, the service node notifies the mobile computing device <figref>104</figref> in the message <figref>614</figref>, If the user of the mobile computing device<figref>104</figref> the answered call, sends the mobile computing device <figref>104</figref> a reply message <figref>616</figref> to the service node <figref>130</figref>, Upon receipt of the response message <figref>616</figref> sends the service node <figref>130</figref> a reply message <figref>618</figref> to the MSC <figref>136</figref>, After connecting the MSC <figref>136</figref> the call to the voice path <figref>620</figref>. of a circuit-switched voice path between the service node <figref>130</figref> and the MSC <figref>136</figref> is. Similarly, there&lt;?page 9?&gt;a voice path <figref>622</figref> in between the mobile computing device <figref>104</figref> and the service node <figref>130</figref>, The speech path <figref>622</figref> is a data packet-switched voice path. As described above has the service node <figref>130</figref>To a User of a mobile computing device <figref>104</figref> a voice call to allow the calling telephone, between the line switching protocol and translating the packet data protocol and hence the speech path <figref>620</figref> and the voice path <figref>622</figref> bridge.

7. to call the data network computing device from a device outside when the computing device is not registered and the wireless Phone is active

<figref idrefs="S43">7</figref> is a message flow diagram, the message processing and the shows the run , when a phone outside a call to a phone which has been the with a mobile computing device connected is, the mobile computing device is not registered with the service node <figref>130</figref> and the wireless telephone with the mobile computing device connected is and is active. It is assumed that the phone is outside a call to a MIN settle that with the wireless telephone linked user is. The call is to the home MSC<figref>136</figref> the wireless Phone or routed out. As with the standard wireless telephone call processing sends the MSC <figref>136</figref> a locreq message <figref>702</figref>That the selected MIN comprises, to the HLR <figref>134</figref>To the current location of the wireless Phone to determine. However, since the user of the wireless telephone also a user of the data network <figref>102</figref> and the service node <figref>130</figref> is, having the user his user pro fil in HLR <figref>134</figref> built up, to indicate that any calls to the MIN first through the Data network <figref>102</figref> to be joined. At the reception the message <figref>702</figref> sends the HLR <figref>134</figref> a service request message <figref>704</figref> including MIN and the type of the service node <figref>130</figref>, At the reception the service request message <figref>704</figref> performs the service node <figref>130</figref> a Database <figref>164</figref> Query to resolve the identification of the mobile to determine computing device that is associated with the receiving MIN. In determining the associated mobile computing device checks the Service Node <figref>130</figref> the Status of the mobile computing device in step <figref>706</figref> by performing Database <figref>164</figref> Query, to determine whether the called mobile computing device with the service node <figref>130</figref> registered is. In this case, the service node is<figref>130</figref> determine, the mobile computing device is not registered with the service node <figref>130</figref>, The service node <figref>130</figref> is thus a service request message <figref>708</figref> send back, indicating that the HLR <figref>134</figref> continue with the processing should in a manner consistent with the normal cellular call processing is consistent.

The HLR <figref>134</figref> investigated the profile of the selected MIN to the current Operating the MSC for to determine the wireless telephone. The HLR<figref>134</figref> sends then a RouteReq message <figref>710</figref> including MIN to the currently serving MSC. The serving MSC responds with a RouteReq message <figref>712</figref> including a TLDN. The HLR<figref>134</figref> forwards the TLDN to the home MSC <figref>136</figref> in the locreq message <figref>714</figref> continue. Upon receipt of the TLDN sets the MSC <figref>136</figref> a call to the TLDN by an ISUP message <figref>716</figref> used is, and the call is routed to the serving MSC. At this Point is the call from the calling to the wireless phon Phone in a conventional Way completed.

8. Call to a data network computing device of a device outside, when the computing device is not registered and the wireless Phone is inactive

<figref idrefs="S43">8</figref> is a message flow diagram, the message processing and the shows the run is when a telephone from outside a call to a phone number settles, the mobile with a linked computing device is that mobile computing device with the service node <figref>130</figref> not registered is and the wireless phone with the mobile computing device connected is inactive. It is assumed that a phone outside a call to a MIN settles that a wireless phone linked user is. The call is to the home MSC<figref>136</figref> the wireless Phone routed. As with the standard wireless telephone call processing sends the MSC <figref>136</figref> a locreq message <figref>802</figref>. including the selected MIN, to the HLR <figref>134</figref>To the current location of the wireless telephone to determine. However, since the user of the wireless telephone also a user of the data network <figref>102</figref> and the service node <figref>130</figref> is, the user has a user profile in the HLR <figref>134</figref> built up, to indicate that any calls to the MIN first over the data network <figref>102</figref> connect to to be tried. Upon receipt of the message<figref>102</figref> sends the HLR <figref>134</figref> a service request message <figref>804</figref> including MIN and the type of the service node <figref>130</figref>, At the reception the service request message <figref>804</figref> performs the service node <figref>130</figref> a Database <figref>164</figref> Query to resolve the identification of the mobile to determine computing device that is associated with the captured MIN EMP. In determining the associated mobile computing device checks the Service Node <figref>130</figref> the Status in the mobile computing device in step <figref>806</figref> by perform a database <figref>164</figref> Query, to determine whether the called mobile Computing device with the service node <figref>130</figref> is registered. In this case, the service node is <figref>130</figref> find the mobile computing device <figref>106</figref> not the service node <figref>130</figref> registered is. Of the&lt;?page 10?&gt;Service node is therefore a service request message <figref>808</figref> hand back, indicating that the HLR <figref>134</figref> the processing in a Way to go, with the normal cellular call processing is consistent.

The HLR <figref>134</figref> scans the profile of the selected MIN, to the current serving MSC for to determine the wireless telephone. In this example, determined the HLR <figref>134</figref>That the wireless telephone in the wireless Communications network is not registered. Thus, then the HLR <figref>134</figref> a locreq message <figref>110</figref> to the home MSC <figref>136</figref> Send that the voice mail node <figref>137</figref> displays. Upon receipt of the message<figref>810</figref> passes the MSC <figref>136</figref> the call to the voice mail node <figref>137</figref>. by the ISUP message <figref>812</figref> is used.

9. Data network computing device generates call to phone outside

<figref idrefs="S42">9</figref> is a message flow diagram, the message processing and the indicating the run , when a mobile computing device a call to a telephone outside causes. The mobile computing device<figref>104</figref> initiated the call by an originating request message <figref>902</figref> including selected Numbers to the service node <figref>130</figref> is sent. by ISUP is used, assigns the service node <figref>130</figref> mediation and transmits the selected Digits to the MSC <figref>136</figref> in the message <figref>904</figref>, The MSC <figref>136</figref> accept the dialed digits, as this would be a telephone call, which would be initiated by a wireless telephone. The MSC<figref>136</figref> builds the call on by an ISUP message <figref>906</figref> to the PSTN <figref>138</figref> in usual Way is sent. The selected with the numeric tied phone is alerted by an alarm message <figref>908</figref> used is, and when the phone answers the call, a reply message <figref>910</figref> at the PSTN <figref>138</figref> recycled. On Thus, a circuit switched voice path <figref>912</figref> in between the service node <figref>130</figref> and the telephone constructed and a Packet data voice path <figref>904</figref> is between the mobile computing device <figref>104</figref> and the service node <figref>130</figref> built up. Like previously described must the service node <figref>130</figref>For a user of the mobile computing device <figref>104</figref> to participate in a voice call with the called telephone, between the switched protocol and translating the packet data protocol and hence the speech path <figref>912</figref> and the voice path <figref>914</figref> bridge.

10. Call Management by a personal Information Manager is used

correspondingly another aspect of the invention, the call processing based on information stored in a mobile computing device in connection with a personal Information Manager (PIM) application is stored, which application is executed on the mobile computing device. As is well known, PIM is a software application that is executed on a computer and personal for managing Information of a user is used. Such personal information For example, schedule data (for example, meeting times) and contact information (such as telephone and address information) . include

correspondingly one aspect of the invention, the information stored in the PIM also for Call Processing Management uses. For example, consider a user views, the mobile computing device <figref>104</figref> used. If the mobile computing device <figref>104</figref> executing a PIM application, the user of the mobile computing device <figref>104</figref> Date information in have saved the PIM. It is assumed that in the PIM application view saved data that the user a meeting has that for June 1 is planned 2:00 to 4:00 pm. The PIM can with call processing software the mobile computing device to be linked so that if a call received by the mobile computing device, the PIM information will be used to make call processing decisions. For example Assume that the user of the mobile computing device <figref>104</figref> in the PIM has stated that the meeting 2:00 to 4:00 pm very is important, and that all in the mobile computing device between 2:00 and 4 am incoming calls to be routed to voice mail. If a call to the mobile computing device during Meeting time arrives, the mobile computing device <figref>104</figref> a appropriate message to the service node <figref>130</figref> Send and Show that the user does not accept calls. The service node<figref>130</figref> becomes the message from the mobile device Rechnervor <figref>104</figref> recognize and will route the call to the voice mailbox.

In addition to the scheduling information may use contact PIM information for call processing be by the contact information (including name and phone number) with the selective call acceptance functions of the mobile computing device connected is. A user of a mobile computing device, for example, specify, that only direct calls to specific phone numbers, or that calls are always rejected from certain numbers. The user can build these call functions by the name and the associated phone numbers are used in the PIM are stored. Thus, according to the PIM processing aspects the invention certain PIM functionality with specific call patterns connected so as to time and communication&lt;?page 11?&gt;tion in the same way to to plan.
