Description:
FIELD OF THE INVENTION 
       [0001]    The present invention generally relates to the field of communications. More particularly, the invention relates to a novel solution for accessing a communication device. 
       BACKGROUND OF THE INVENTION 
       [0002]    With the ever increasing demand for communication capabilities, and the frequency at which communications are received by everyone nowadays, various problems arises regarding the handing of the increasing flow of communications. In the attempt to cope with some of these problems, different solutions, making use of various fields of telecommunication technology, have been suggested. 
         [0003]    Nowadays, it is not unusual to see a telephone user, and particularly cellular telephone user, who has more than one telephone. Needless to say that using two or more such devices is a rather cumbersome task, but it is still one that is performed by those users who, because of any one of a number of reasons, e.g. having a private telephone and one from work, need to have more than one telephone number, a secretary at the office, etc. 
         [0004]    A number of prior art publications tried to provide a solution to the problem of having two or more devices associated with a single user, and to the problem of keeping incoming calls on hold. 
         [0005]    EP 993,169 teaches a method for handling an incoming call directed to a target telephone that is currently engaged with a present call. The solution suggested describes issuing a first signal to the target telephone to indicate that there is a call waiting, and to issue a second signal to the waiting caller, informing that the target telephone is engaged. 
         [0006]    U.S. Pat. No. 6,111,942 describes a communication transfer apparatus which calls a predetermined transferring destination number when an incoming call is detected on a communication line. The transfer apparatus compares a calling-party number received on an incoming-call received line with the predetermined transferring destination number, and if they do not coincide, the transfer apparatus calls the predetermined transferring destination number. If they coincide, the transferring operation is not carried out. Accordingly, meaningless transmission such as transferring an incoming call received from a calling party who is located in the transferring destination can be obviated. 
         [0007]    Each of the references mentioned hereinafter is hereby incorporated by reference as if fully set forth herein. 
       SUMMARY OF THE INVENTION 
       [0008]    It is therefore an object of the present invention to provide a platform for use in a wireless network which allows managing and buffering a plurality of requests to establish communications calls with a single telephone device. 
         [0009]    It is yet another object of the invention to provide such a device that is able to receive calls addressed thereto being engaged in another communication session. 
         [0010]    It is still another object of the present invention to provide a single desktop telephone connected to a wireless network via a plurality of communication paths, and a method of managing such desktop telephone. 
         [0011]    It is yet another object of the present invention to provide a desktop telephone device and a method operative to receive indications related to the currently waiting requests to establish communication sessions with that device and allow its user to respond to these requests. 
         [0012]    It is another object of the present invention to provide novel methods and apparatus that enable users to use a single mobile telephone device and be connected to a plurality of different telephone lines. 
         [0013]    Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instrumentality and combinations particularly pointed out in the appended claims. 
         [0014]    According to a first embodiment of the present invention there is provided a method for establishing communication sessions with a user of a single telephone device, wherein the requests to establish these communication sessions are destined to at least two different communication addresses. 
         [0015]    According to a preferred embodiment of the invention, the different communication addresses are selected from a group consisting of: cellular telephone numbers, e-mail addresses, Uniform Resource Identifiers (“URIs”), website addresses and any combination thereof. 
         [0016]    In accordance with another embodiment of the invention the single telephone device is a member selected from among a cellular telephone, a desktop telephone and a smart phone. 
         [0017]    The term “cellular telephone” as used herein should be understood also to encompass a subscriber address identification, i.e. the physical identification of the mobile device, e.g. a SIM card associated with such a cellular phone, the CDMA telephone itself, and the like. 
         [0018]    The term “desktop telephone device” (which is also referred herein as “desktop device” or “desktop cellular device” as the case may be) is used herein to denote a device that is linked to a mobile operator&#39;s network via the cellular network or via any other method known in the art per se, such as VoWLAN. The desktop device referred to herein may be considered as one of the types of devices encompassed by the term cellular telephone discussed above, and should be understood also to encompass a subscriber address identification, i.e. the physical identification of the mobile device, e.g. a SIM card associated with such a cellular phone, the CDMA telephone itself, and the like. 
         [0019]    By yet another embodiment of the invention, the method comprises the steps of: 
         [0020]    establishing a pre-defined list of communication addresses to be associated with the single telephone device; 
         [0021]    providing a lead address for the single telephone device; and 
         [0022]    for each of the other communication addresses associated with the single telephone device, providing a re-routing scheme to enable handling any request to establish a communication session through any of the addresses comprised in that pre-defined list, through that lead number. 
         [0023]    The term “lead number” is used herein to encompass also a default number, e.g. the original number of a cellular device. However, this number may be replaced by setting controlling rule(s) to be implemented by the re-routing entity. For example, it is possible to use a certain lead number during working hours while during after-work hours a different lead number may be used. In such a case, the lead number can also be used as the number to which all charges incurred will be associated, preferably while that number was the lead number. 
         [0024]    By a preferred embodiment of the invention, the step of establishing a pre-defined list of communication addresses to be associated with the single telephone device further comprises determining the single subscriber address identification to be the lead number for the single telephone device. 
         [0025]    According to a preferred embodiment of the present invention, there is provided for use in a cellular network, a method for managing a plurality of requests to establish communication sessions with a user of a single telephone device (e.g. a desktop telephone device), where this telephone device has preferably a single subscriber address identification defined in said cellular network, e.g. a single SIM card. In the alternative, the single telephone device may be provided with more than one such SIM card. The method allows receiving and processing plurality of requests for establishing communication sessions while another communication session is being held with that user. For example, when the user of a telephone device is busy in a telephone conversation, a number of additional calls may still be managed rather than be discarded once there is already a call waiting addressed to the very same telephone number. 
         [0026]    According to an embodiment of the invention the method further comprising the step of providing the user with indications, to enable the user become aware of the requests received for establishing the communication sessions, and particularly those request that are currently pending. 
         [0027]    By another embodiment of the invention, the method provided further comprises a step of determining which of the plurality of requests shall be accepted. Preferably, the determination is made by the user of the single telephone in response to receiving the indications of the currently waiting requests. 
         [0028]    According to yet another embodiment, the plurality of requests identified for acceptance, are retained in a buffer managed by the cellular network management system. 
         [0029]    In accordance with still another embodiment, the order of the requests queued in the buffer can be changed in response to one or more instructions generated by the user (e.g. to advance on the requests so that a voice call be established prior establishing other session(s), even other voice calls, that arrived prior to the arrival of that request, etc.) 
         [0030]    By still another embodiment, the method further comprises the step of displaying indications of the address designated in the request received for establishing a communication session to the user of the single telephone device, before actually establishing the requested session. In addition or in the alternative, the indications displayed are of the requests received, and preferably those that are still pending. The user views these requests at the display means (e.g. a telephone display, a computer screen) and may act upon, e.g. by manipulating their order, rejecting some requests, diverting calls to a voice mail box or answering service, view if any of the calls that were pending were disconnected by their initiator, etc. 
         [0031]    According to another embodiment, the single telephone device further comprises means to receive and display a message associated with the communication session being established, where such message can be a USSD type of message, or a real time data message transmitted via a data communication channel and the like. Preferably, the message comprises the number called and/or identification of the address of the device initiating the communication session. 
         [0032]    According to still another embodiment, the communication session comprises transferring and/or receiving signals that belong to a group that consists of: data signals, video signals, voice signals, facsimile signals or any combination thereof. 
         [0033]    Let us consider an example where the single telephone device is a desktop telephone device, and the device is provided with a single physical subscriber address identification defined in a cellular network e.g. a desktop telephone provided with a SIM card (or CDMA telephone device), and adapted to communicate over the wireless network directly or via a VoWLAN, while being managed via the wireless network. The telephone itself may be similar to a PBX smart digital telephone, e.g. so as to include features a desktop user would require, such as extension buttons, transfer and conference buttons, and/or any other programmable buttons. 
         [0034]    Thus, according to an embodiment of the present invention there is provided a method for establishing communication sessions with a user of a single desktop telephone device associated with a cellular network following receipt of requests for establishing these communication sessions, and wherein at least two of these requests specify each a different communication addresses, e.g. the other parties initiating the call, specify different destination addresses, such another telephone number, instant messaging address, an e-mail address, etc. that should reach the same desktop telephone device. As previously explained, the single desktop telephone device is provided with a single subscriber address identification defined in a cellular network, e.g. communication address in a cellular network associated with a SIM card. The other address(es), such as other cellular telephone number(s), are preferably virtual cellular communication address(es), but can also be other subscriber address identifications such as additional SIM cards. 
         [0035]    According to still another embodiment of the invention, the method further comprising a step of providing the single desktop telephone device with an indication that relates to an address specified in the request to establish a communication, prior to establishing that communication session. 
         [0036]    By yet another embodiment of the invention the method further comprising a step of associating at least one message with at least of the requests for establishing the communication sessions and forwarding that message to the single desktop telephone device. Preferably, this message is selected from among: a voice message, a text message, a video message and any combination thereof. Still preferably, the message comprises details associated with an arriving request for establishing the communication session, e.g. where the details are at least one member of the group consisting of: identification of the party requesting the establishing of said communication session (e.g. automatic number identification of the device initiating the communication session), identification of the address for which said request arrived, priority level, and any combination thereof. 
         [0037]    In accordance with yet another embodiment of the invention, the method further comprising a step of diverting a call destined to that single telephone device, to an address which is not included in the pre-defined list of communication addresses, e.g. a secretary may divert the call received for the boss, to another device such as a cellular phone, a diversion which may depend upon the boss current location. 
         [0038]    In addition, the diversion may be carried in response to determining that the request made for establishing said communication session specifies one or more specific addresses, out of the addresses included in said pre-defined list of communication addresses. Preferably, a message may be associated with the diverted communication session. Still preferably, this message is generated in response to a pre-define code sent by the user of the single desktop telephone device, e.g. considering the example given above, the secretary may divert the call by pressing certain code or a certain key that was configured to be the agreed upon code. Once that happens, a pre-defined message shall be generated thereby providing the boss with certain information relating to the request for communication session that is being established. Similarly, mutates mutandis, the transfer can be requested by the desktop telephone user (e.g. when the user is busy with another communication session) and executed by a switch associated with the network to which that desktop telephone belongs. According to another option or alternative, upon receiving the indication(s) of the requests that are currently pending, the user may decide to divert the call that he/she is currently engaged with by applying any of the methods described above, and accept one of the waiting requests to establish the communication session. By yet another embodiment of the invention, the method provided further comprising a step of providing a pre-defined auto reply to a party requesting to establish a communication session, in response to receiving that request at the single desktop telephone device, e.g. at one specific number of those associated with that single desktop telephone device. 
         [0039]    Preferably, the pre-defined auto reply is selected based on the type of the device originating the incoming call, and may be a member selected from the group consisting of: an e-mail, an SMS, a voice message, and the like. Optionally, or in the alternative, the user may make a real time decision, e.g. while the call is ringing or after a message regarding the incoming call waiting is received, on the auto-reply to be used in conjunction with the present call. 
         [0040]    According to still another embodiment, the method further comprising a step of forwarding a communication session to an answering service, upon determining that the communication address specified in the request made for establishing said communication session, is, a pre-defined one of the addresses included in the pre-defined list of communication addresses. 
         [0041]    According to still another embodiment of the invention, the method provided further comprises the step of receiving a plurality of requests to establish communication sessions with said user of the single desktop telephone device while conducting a real-time type of communication session (such as voice session or a video session), and determining which of the other requests will be accepted. 
         [0042]    Preferably, all of the other requests that have been identified for acceptance (independent of their number) are kept in a buffer managed by the cellular network management system, while the non-accepted ones are rejected, preferably with a message played or displayed to the originator of the call. 
         [0043]    According to another aspect of the invention, there is provided a desktop telephone device having a single subscriber address identification defined in a cellular network and adapted to receive a plurality of requests to establish communication sessions, while at least one other communication session is being conducted via this desktop telephone device.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
       [0101]    The present invention will be understood and appreciated more fully from the following detailed description. 
         [0102]    Let us consider as an example that all the addresses (telephone numbers) included in the pre-defined list of addresses are cellular telephone numbers and are all handled and managed by a public cellular network. Still, a somewhat similar solution may also apply when one or more of the addresses comprised in that pre-defined list are wireline numbers. In such a case, when a request to establish a communication session with one of the wireline numbers is received at the PSTN, it will automatically be forwarded to the pre-defined cellular number according the applicable re-routing rule, so that the caller who called a wireline. telephone number will have his call first diverted to the cellular network, and then processed in accordance with the description of the invention as disclosed herein. 
         [0103]    Let us now consider the flow chart shown in  FIG. 1 , which demonstrates an example of implementing the solution provided by the present invention for voice calls addressed to a single desktop telephone device which is provided with one or more SIM cards and thus, becomes an end device in a cellular communication network, where this desktop telephone has one or more lines (different communications addresses) associated therewith, and all of these lines are managed by the wireless centrex (“WX”) node. In the present example, a wireless Centrex platform is also associated with that cellular network and manages the desktop telephone device of the example. 
         [0104]    By this example, a request is initiated to establish a communication session, e.g. a telephone call, with the subscriber using the desktop telephone in the cellular network, as explained above (step  100 ). The request may either be initiated by a user belonging to that cellular network, or from any external network (i.e. PSTN, another cellular network, etc.). Similarly, the request may be in the form of an e-mail sent to the user&#39;s e-mail address, for presenting it on his desktop telephone device. 
         [0105]    The request enters the cellular network (step  110 ) via a Gateway Mobile Switching Center (GMSC), for example: a call from the PSTN with a cellular dialed number will be routed to the GMSC, and received at a MSC/GMSC of the cellular network. 
         [0106]    The MSC/GMSC then interrogates the HLR (step  120 ), in order to get the called subscriber service profile. According to the HLR&#39;s Terminate IN Key, the IN signaling of the call is routed toward a wireless centrex node (“WX”) such as the one described in our co-pending application IL 165362 filed on Nov. 24, 2004. Alternatively, the IN signaling of the call will be routed toward the WX according to the dialed number (e.g. all numbers between “1001” and “1100” should be routed to the WX) (step  130 ). 
         [0107]    The WX receives details about the call initiator (i.e. ANI, called number, if the subscriber is attached to the network or the last VLR update), and is able to link the request by the lead (e.g. default) number and the list of additional numbers (addresses) associated at the WX node with that subscriber. When a call is received for any of the subscriber&#39;s lines, the following process is initiated. 
         [0108]    At the WX, the number dialed is matched against the pre-defined list, and the appropriate lead number for the subscriber is determined, and based on the information available, e.g. the lead number, routing tables, rules and other information, returns to the MSC with routing instructions for that call (step  140 ). In some cases, in which the mobile network has limited IN capabilities, or additional resources are needed, the WX may request to route the call to the WX Service Node, which will physically control and route the call. WX can request the MSC to place the call in queue or on hold on network, until further instructions are received from WX (while WX receives instructions from user). WX can request to place in queue or on hold more then one call for this default number. 
         [0109]    The WX interacts with the desktop telephone device via a mobile data connection (which can alternatively be done via an IP connection), and the interaction can be done by using protocols such as SIP, proprietary or others known in the art per se. The WX sends to the subscriber&#39;s desktop telephone information regarding the called number, preferably with information regarding the ANI of the caller (step  150 ). 
         [0110]    The desktop telephone receives the information which is then presented to the user while the telephone is ringing (step  160 ). If the user is engaged with a current call, he will receive an indication of the new call arriving, and will be able to view the calls which are already in the queue preferably together with their related information. This viewing is done according to this example via the telephone device interface. 
         [0111]    If the user is busy in a call (step  170 ), he may view the call in the queue call screen (step  180 ) and at any time can select via the desktop telephone device interface any of these queued calls and accept or reject that call (step  190 ). 
         [0112]    In the alternative, the user receives in step  160  the data relating to the incoming call before the telephone is ringing or while ringing. Then the user may select an action from a known list. The desktop telephone device transfers the selection made by the user to WX node, which will route the call based on the user&#39;s selection and other parameters stored at the management of the WX. 
         [0113]    The MSC will route the call based on the instructions received from the WX, while the latter continues to manage the call and to receive updates regarding the call&#39;s status (e.g. once the call is disconnected the MSC will send the information to the WX via signaling). Based on the instructions received from the desktop telephone user and/or the call information and/or the WX routing tables and rules and other parameters, the WX decides if and when to make changes in respect of this call. 
         [0114]    By another alternative embodiment of the invention described in  FIG. 2 , a USSD message is sent to the subscriber&#39;s lead number defined for his desktop telephone device, preferably with information regarding the called number and ANI of the caller (step  200 ), after carrying out steps  100  to  140 , described above. 
         [0115]    The user&#39;s desktop telephone device receives the information embedded in the USSD message while his telephone is ringing (step  210 ). 
         [0116]    The desktop telephone device presents details derived from the USSD (step  220 ). 
         [0117]    The Subscriber views the incoming call screen, and can accept or reject the call (step  230 ). In a way similar to that described above, if the user is busy with another call, he may view the in queue call screen (step  240 ) and at any time accept or reject a call of those in queue (step  250 ). 
         [0118]    Let us consider now the case where a number of requests to establish communication sessions with the user of the desktop telephone have arrived (through any one of the numbers associated with that desktop telephone as the corresponding communication addresses of that telephone. Let us also assume that these requests arrived while the user has been engaged in another communication session, e.g. a telephone conversation. Now the requests are queued in the cellular system, preferably in a buffer of the wireless centrex associated with the cellular network, and these requests are forwarded to the desktop telephone. Upon viewing the waiting requests the user may, while still conducting the communication session he is engaged with, select which of the other requests shall be accepted, and when the WX receives the user selection, it will act upon by retaining all of these requests identified for acceptance, in a buffer managed by the cellular network management system, and rejecting the others (e.g. responding to the requests with a pre recorded voice message). 
         [0119]    Furthermore, the user may view at the desktop display the current order by which the requests were queued in the buffer, and change this order of the requests queued in the buffer, by providing one or more appropriate instructions to the WX. This way, the user may select say call number  5  in that queue and upon disconnecting the currently conducted call, the user will be immediately connected to the caller of call No.  5 . In the alternative, the user may indicate his wish to put the current session on hold and to switch from this current call immediately to call number  5 . 
         [0120]    According to another option, the user may indicate to the WX to re-route one or more of the waiting calls to a voice mail box or to comply with any other pre-defines management rule provided to the WX. 
         [0121]    In addition, the method described in this example may further comprise a step where the desktop telephone user may select audio signals and/or video signals that will be transmitted towards the initiator of the request, while the call with the desktop device is being established or being kept on hold. Preferably, the audio signals and/or video signals are selected in response to identifying the type of the device initiating the call. 
         [0122]    According to yet another embodiment, a replacing station may be provided which is operative to receive arriving calls instead of the desktop telephone device to which the call was destined. Such replacement may be in response to a request sent by the desktop telephone user to the public cellular network center. Preferably, the replacing station is selected from a routing list stored at the public cellular network center, or the WX. 
         [0123]    This embodiment enables the user to change to various pre-defined presence scenarios. The presence scenarios and routing instruction are stored in the cellular network center, and preferably each presence scenario is associated with suitable operative instructions, for example: “in meeting” scenario will be translated by the network so that all arriving calls should be forwarded to the secretary&#39;s station. Once the desktop telephone user changes the scenario, a message is sent to wireless centrex, which will handle incoming calls based on the predefined routing rules. 
         [0124]    As previously described in one of the embodiments of the present invention, a transfer message may be associated with an arriving request, e.g. sent from the cellular network center to trigger an arriving call being placed on hold. 
         [0125]    The transfer can be requested by the desktop telephone user (e.g. when the user is busy with another communication session) and if that device belongs to a private network, executed by a switch associated with that private network. In such a case, notifications will preferably be stored locally. Alternatively, the desktop telephone device sends message to a communication device such as a wireless centrex which takes control over the transfer request, manages the process, while instructions such as re-routing schemes and the like are stored at the network&#39;s center and are assigned by the wireless centrex, e.g. to the transfer destination. 
         [0126]    The message is sent to the receiving user preferably via USSD or a real time data message via a data communication channel. The data sent in such a message is typically data regarding the call information such as ANI, DNIS (called number by number, but can be by done by name, too, if the system of the invention can match it with its own database), in order to enable the receiving phone to generate the right message. 
         [0127]    Optionally, the receiving user may view the message and then select from a list of several options, the preferred way of handling the call (e.g. divert the call to secretary, send to voice mailbox, transfer to someone else such as the boss, etc.) 
         [0128]    Another option is to send a voice prompt as the message, which will be played to the receiving party (canned voice message, such as “please set a meeting with caller”, “take care of this” etc.). The receiver may then request to listen again to the message, answer the caller, etc. In this case there is a need for an IVR or Intelligent Peripheral infrastructure to allow playing the messages. 
         [0129]    In accordance with another embodiment of the invention, the method further comprises a step of providing a pre-defined auto reply to the calling party in response to a call received at the desktop telephone device. Such pre-defined auto reply can be an e-mail, an SMS, a voice message, and the like. Therefore, the end user may define his line to send such an auto reply to the calling party, providing the latter by using TTS or wav type of file with any details desired such as “I am out of my office”, “will return on ______”, “will have limited access to my voice mailbox”, etc. Preferably, the type of the pre-defined auto reply is selected based on the type of the device originating the incoming call (e.g. wireless and wireline). For wireless party originating the call, the message can be in a form of SMS, while for a wireline the message may be in the form of an e-mail or a voice announcement. 
         [0130]    As previously explained, the method provided may further comprise a step of forwarding a call to an answering service associated with the public cellular network and have the message that will be left thereat by the caller. For example, if the request for communication session is made to one or more of the addresses associated with the single desktop telephone device. The message will be forwarded to the desktop device, either automatically, or in response to the desktop telephone device request to pull the messages received. 
         [0131]    Thus, the present invention enables a mobile operator to provide a full premise service to a company, with no need for regulation approval. 
         [0132]    In addition, other features, such as the following ones may be associated with such a desktop telephone:
       View presence of other user (e.g. boss) before transferring the call. The presence of a user may be viewed either physically (e.g. using a small lamp that lights up at the button associated with the user&#39;s extension), or via the telephone interface showing the presence of all users in a group.   buttons/soft keys to establish a call or send a message to a predefined extensions and numbers   Buttons/soft keys to establish a conference call, and or transfer a call.   User may define the functionality of a button/soft key   Speaker phone   Screen pop—desktop can communicate with a PC enabling the user to control the call control from the desktop The wireless desktop phone communicates with a PC and enables all call control functionality from the PC. The PC softphone, may communicate directly with the desktop wireless phone via bluetooth or other compatible solution as known in the art per se.
 
Let us consider now the following example:
       
 
         [0139]    When the desktop telephone rings, data regarding status and caller ID is sent to a soft phone application implemented by a PC. Based on certain pre-defined rules, the soft phone will pop on screen (screen pop) with the relevant call data. The user of the desktop telephone views the data received on the screen of the PC and decides whether to accept, reject, divert etc. the call. In addition, the call control is conducted via the soft phone (including transfer button, etc.) 
         [0140]    Furthermore, as this softphone operates in conjunction with a device connected to a wireless network. The user may use a headset connected to PC and then voice signals will also be transported over the bluetooth connection (or any other type of connection implemented). 
         [0141]    Let us now consider another example illustrated in the flow chart shown in  FIG. 3 , of implementing a solution provided by the present invention for inbound voice call addressed to a mobile user, wherein the wireless Centrex also operates as an IN signaling node. 
         [0142]    By this example, a request is initiated to establish a communication session, e.g. a telephone call, with a certain subscriber of a mobile network that is also a subscriber of the wireless centrex system (step  300 ). The request may either be initiated by a user belonging to that mobile network, or from any external network (i.e. PSTN). Similarly, the request may be in the form of an e-mail sent to the user&#39;s e-mail address, for presenting it on his mobile device. 
         [0143]    The request enters the mobile network (step  310 ) via a Gateway Mobile Switching Center (GMSC), for example: a call from the PSTN with a mobile dialed number will be routed to the GMSC, and received at a MSC/GMSC of the mobile network. 
         [0144]    The MSC/GMSC then interrogates the HLR (step  320 ), in order to get the called subscriber service profile. According to the HLR&#39;s Terminate IN Key, the IN signaling of the call is routed toward a wireless centrex node (“WX”) of the present invention. Alternatively, the IN signaling of the call will be routed toward the WX according to the dialed number (e.g. all numbers between “1001” and “1100” should be routed to the WX) (step  330 ). 
         [0145]    The WX receives details about the call initiator (i.e. ANI, called number, if the subscriber is attached to the network or the last VLR update). 
         [0146]    The subscriber of this example has several lines associated with his one device (different addresses), all of which are managed by the WX node. The subscriber has one lead (e.g. default) number and a list of additional numbers (addresses) is associated at the WX node with that subscriber. When a call is received on any of the subscriber&#39;s lines, the following process is initiated. 
         [0147]    At the WX, the number dialed is matched against the pre-defined list, and the appropriate lead number for the subscriber is determined, and based on the information available, e.g. the lead number, routing tables, rules and other information, returns to the MSC with routing instructions for that call (step  340 ). In some cases, in which the mobile network has limited IN capabilities, or additional resources are needed, the WX may request to route the call to the WX Service Node, which will physically control and route the call. 
         [0148]    A USSD message is then sent to the subscriber&#39;s lead number at his mobile device preferably with information regarding the called number and ANI of the caller (step  350 ). 
         [0149]    The subscriber receives the information embedded in the USSD message while his telephone is ringing (step  360 ). 
         [0150]    The subscriber presses any key and USSD message is erased (step  370 ). 
         [0151]    The Subscriber views the regular incoming call screen, and can accept or reject the call (step  380 ) 
         [0152]    As an alternative, the subscriber may receive in step  360  the USSD message before the telephone is ringing. Then the subscriber may select an action from a known list. The USSD will transfer the selection to WX node, which will route the call based on subscriber selection and other parameters that are stored at the management of the WX. 
         [0153]    The MSC will route the call based on the instructions it received from the WX, while the latter will continue to manage the call and receive updates regarding the call status (e.g. once the call is disconnected the MSC will send the information to the WX via signaling) (step  350 ). Based on the call information, the WX routing tables and rules and other parameters, the WX will decide if and when to make changes in respect of this call. 
         [0154]    It will be appreciated that although various aspects of the invention have been described with respect to specific embodiments, alternatives and modifications will be apparent from the present disclosure, which are within the spirit and scope of the present invention as set forth in the following claims.
