High-speed mobile number portability service

Field of the Invention

The invention relates to the portability of a mobile number, i.e. the subscriber 5 may, if he so wishes, retain his number when switching to another mobile operator.

Technology background

In general, in those geographical areas where the mobile-10 number portability feature is not available, the call is always routed based on the prefix included in the recipient number. An example is a call in which the recipient number includes a 050 prefix. Such a call is automatically routed to the network of a mobile operator called Radiolinja. The situation will change in Finland in summer 2003 with the introduction of the Portable 15 number portability feature. In that case, the prefix of the receiver number can no longer automatically determine which operator's customer is a subscriber.

The mobile number portability feature requires collaboration between mobile operators. The Finnish Communications Regulatory Authority (FICORA) directs 20 co-operations by regulations. The following provisions apply to Finland, but similar provisions exist in other countries:. 1) The subscriber must have a subscription contract with a new operator, the "receiving operator".

'·; '2) When a "handover operator" receives a transfer request for a mobile number of 25, the transfer work from the handover operator to the receiving operator may take no more than five: "" days after the transfer request has been transferred to the so-called Master system.

: See 3) The transfer job may cause a maximum interruption of 30 minutes.

4) The donor operator's SIM (Subscriber Identity Mo-:; dule card) must be replaced with the receiving operator's SIM. ···. to the card when the subscriber's mobile number is introduced in the network of the receiving operator.

: '·· 35 The above regulations of the Finnish Communications Regulatory Authority have been drafted in such a way that it is technically possible to fulfill the requirements, although technical 116351 2 challenges do arise. From the customer's perspective, however, there are certain disadvantages to mobile number portability.

First of all, it is difficult to estimate when the mobile number porting will be performed in practice. Assume that the customer meets with the representative of the receiving operator on Friday and the customer signs a new subscription agreement and transfer request. The transfer request is also a notice of termination of the old subscription agreement. If a transfer request is sent by letter from the receiving operator's representative to the Master system administrator, the transfer request may be entered into the Master system no earlier than Monday of next week. If the transfer request 10 is faxed to the master system administrators, it is possible that it will be entered into the master system on the same day that the client signs the transfer notification. Once the transfer request has been successfully entered into the Master system, the transferring operator will have a maximum of five business days from that date to complete the migration. Once the migration work has also been completed for the 15 receiving operators, the receiving operator notifies the customer, allowing him to start using his new subscription. For the customer, it may be difficult to estimate the time needed for porting to the nearest day, especially hour.

Secondly, the customer has to carry two SIM cards with him. 20 When the donor operator's SIM card eventually ceases to function, the customer may conclude that the SIM card needs to be replaced with the receiving operator's SIM card.

Thirdly, the customer may need to provide the donor * · operator's SIM card to the representative of that operator, which causes: 25 extra effort.

BRIEF SUMMARY OF THE INVENTION

The main object of the invention is to implement a mobile communication device. a number portability service so that the customer using the service avoids:; 30 disadvantages of the prior art mentioned above.

It is essential in the concept of the invention that the customer:; '; can receive calls addressed to the mobile number being ported and, ···. short messages with his new subscription as soon as he has received a new subscription from a representative of the receiving operator. At the meeting with the agent: '·· 35 customers will give away the old or the donor operator's SIM card. At the same time, the 116351 3 customer will receive a temporary telephone number that will be available to the customer until the number porting process is completed.

The process according to the invention comprises the following main steps. A temporary mobile communication number 5 is allocated to the receiving operator's subscriber line. The temporary mobile number and the mobile number to which the transfer is to be made are stored. The donor operator's SIM card, which contains the mobile number, is inserted into the equipment intended for use with the SIM cards. The apparatus receives one or more short messages addressed to a (portable) mobile number. By means of the mobile station 10 mero, a temporary mobile station number is retrieved from the memory and the received short messages are routed to the temporary mobile station number.

Following the main steps listed above, the subscriber may receive short messages addressed to his mobile number through his new subscriber interface.

In addition, it is a good idea to set up call forwarding for a mobile number so that each call made to the mobile number ends in a temporary mobile number through call forwarding. The subscriber can then receive calls addressed to his mobile number through his new subscriber line.

By default, the subscriber 's outgoing calls and short messages will have a temporary mobile number as the caller' s number until,. . number porting completed.

Preferably, the porting is completed by sending a text message to the subscriber interface 'providing instructions for action.

DETAILED DESCRIPTION OF THE INVENTION

The invention is entitled: '' High-speed mobile number portability service ''. The invention relates to the transfer of a mobile phone number from a mobile operator to another mobile operator, and this number porting takes place faster than prior art number porting. In practice, the customer can receive short messages and calls addressed to his mobile number to be transferred to his mobile station, once the receiving operator's SIM card is inserted in the mobile station. The short message according to the GSM standard is a maximum of 160 characters.

FIG. 1 illustrates an arrangement for directing short messages to a subscriber terminal. When a customer arrives at the receiving operator's representative, the customer signs a subscription contract to receive the receiving operator's subscriber line. In addition, the customer terminates his subscription contract with the transferring operator. The agent then uses the system 101 of the invention and allocates a temporary telephone number to the customer, · using the system. The customer's SIM card 102 is inserted into the system 103! 101. The SIM card is in a mobile station or some other terminal; 'A card to be placed on a road and containing information necessary to identify the subscriber and encrypt the radio traffic. SIM card used in connection with the invention ->, ·: 25 card removable terminals. · ': Any other smart card provided that the smart card can be controlled by the handler. at least short messages and possibly also calls via the mobile network of the radiator. The system preferably includes a multiplexer into which a SIM card can be inserted. Each SIM card inserted in the system is activated: 30 turns. Thus, the SIM card 102 is intermittently operable in the donor operator network 104, whereby the SIM card and the system are included. the radio receiver collects short messages from 105 customers. The collected short messages are routed through system 106 to the receiving operator's network 107, which delivers the short messages to the terminal 108. The terminal i 35 108 and the receiving operator's SIM card form a »MM *» 116351 5 client subscriber, initially including a temporary telephone number and a later ported mobile number.

The multiplexer is originally designed for testing SIM cards. The prior art multiplexer does not include a radio part, that is, it does not include a radio transmitter or receiver. In the system according to the invention, the multiplexer is preferably coupled to the radio part so that the SIM card inserted in the multiplexer is capable of receiving a set of short messages assigned to the mobile number to be ported. This set of short messages can be forwarded to the SMSC (Short Message Service Center) 10 via an application interface. Many application interfaces are manufacturer specific.

In addition to short messages, calls and messages are usually routed to the customer's new subscription. Messages refer to other types of messages than short messages. An example is MMS (Multimedia Messaging System Messages).

FIG. 2 illustrates an arrangement for routing calls and / or messages to a subscriber terminal. When a customer enters the receiving operator's shop, the customer enters into a subscription agreement with the receiving operator. As mentioned above, through the system 201, the agent allocates a temporary telephone number to the customer. Thereafter, the agent, 20 customer or other person performs the call forwarding to the customer's mobile number. The call transfer 202 may be implemented via a terminal 203 which includes a hand-held operator SIM card. As an example, for example, a call forwarding to a temporary telephone number of a Radiolabel operator is performed by • keying on the terminal keypad: i 25 ”* 22 # <call number> #. Alternatively, the call transfer 202 may be implemented through the system 201 when the donor operator's SIM card is inserted in the system. It is possible to use a temporary phone number as the call number. In this case, the communication addressed to the mobile number to be ported ... is routed from the network 204 of the handover operator 204 to the receiving operator network 206 and thence to the terminal 203, which acts as a new * · · * 'subscriber interface. Specifically, the "old" SIM card has been removed from the terminal 203 and a SIM, · ** card containing a temporary telephone number has been inserted. However, in the embodiment described above, the customer has to pay for the communication between his mobile number and the call number. In the best embodiment of the invention, the call forwarding number is a number such that the said data traffic is free to the customer, even if the calls and / or messages are directed to the customer's temporary telephone number. the communication addressed to the mobile number is routed from the network 207 of the handover operator 207 through the system 201 to the network 206 5 of the receiving operator and thence to the terminal 203.

The call forwarding can be an instant call forwarding or a delayed call forwarding. In any case, system call support is required for successful forwarding of a temporary telephone number. The host operator may have a large number of representatives on whose premises customers will visit. The system should ensure that the temporary telephone number is only available to one customer at a time. Once the customer's number porting is complete, the temporary phone number is released, meaning that it can be reallocated to another customer.

Preferably, the receiving operator has a special number portability, the numbers of which are available as temporary telephone numbers. Instead of one unified number space, temporary phone numbers may be divided into separate number spaces. Temporary telephone numbers can also be assigned to a list if necessary.

FIG. 3 illustrates the main steps of the method of the invention, which are contained in the independent claim. Initially, the method allocates 301 temporary subscriber lines to the subscriber line of the receiving operator. . the message number. Temporary Mobile Number and Mobile Number, which- ';'; * The transfer is targeted, stored in 302 memory. If necessary, calls and / or v: messages can also be routed to the new subscriber interface, but the main steps of the method: [*: only apply to short message processing, so the next hand operator's SIM card is inserted into the multiplexer 303 or equivalent SIM card hardware. This hardware must either contain or be present. connectable to the control means and at least one radio receiver. The method then receives a set of 304 short messages addressed to a mobile number to be ported through the SIM card hardware and the radio receiver.

I *.

More specifically, the short message or messages are received via a SIM card inserted in the apparatus, which contains a mobile number to be ported. This mobile number is used to retrieve 305 intermediate

I t I

and the received short message set is routed to 306 temporary mobile numbers. If there are also calls and / or messages, it is desired to route 307 to a new subscriber line. Performing a 308 paging from a mobile number to a temporary telephone number via a (customer) terminal 116351 7 device.

Once the SIM card is inserted into the SIM card hardware 303, the main steps 304-306 of the method are repeated at certain intervals, for example every 1-2 minutes, until the mobile number contained in the SIM card is completed. This will remove the SIM card from the hardware, allowing you to insert another SIM card into the hardware. Once removed, the SIM card can be destroyed or delivered to the handing over operator.

FIG. 4 illustrates another embodiment of the method. Here, too, a temporary mobile number and a temporary mobile number 401 are allocated to the subscriber interface of the receiving operator, and the mobile number to which the transfer is directed is stored in memory 402. In addition, the handover operator's SIM card is inserted into the multiplexer or similar equipment 403. If calls and / or messages are to be routed to the new subscriber interface 154 through the equipment 403, a call transfer from the mobile number to the temporary telephone number is performed. If calls and messages are not to be routed to the new subscriber line 404, steps 304-306 of FIG. 3 are immediately performed. Steps 304-306 are also performed after step 405. Step 402 is shown in dashed lines, as the step can be implemented later. In the principle of peri-20, it is sufficient that step 402 is executed before the short messages are started. y. redirect to a temporary phone number.

Thus, calls and messages addressed to the mobile number to be transferred will end up in a temporary telephone number via a call transfer. The forwarding number * * '··' is preferably set to a telephone number such that the call forwarding i.i; As a result, the call is routed to the Service Switching Point (SSP) and causes: '· In the SSP, a specific trigger is triggered when the Call History of the call contains a mobile number. As a result of the trigger triggering, the SCP (Service Control Point) searches the SCP's own memory or so-called. MNP. . the mobile number of the call memory in the server memory. Traveling; When 30 message numbers are found, the SCP instructs the SSP to route the call to the temporary telephone number allocated to the mobile number and. , 'With which the mobile number is stored.

-i To complete mobile number porting, the method can; * utilize the Over The Air system (OTA). In this case, a short message is sent from the 35 OTA systems to the subscriber line, to which the temporary telephone; · · · Number is included. This short message contains an OTA update and verbal 8 1 1 6351 instructions for the subscriber. In response to the received short message, the subscriber disconnects from his subscriber line and switches the power on again. Thereafter, the mobile number to which the transmission is directed is available in the subscriber line to receive and transmit communications.

The system of the invention is adapted to carry out the method steps described above. It controls the communication to the mobile number while the transfer of that mobile number from the handover to the receiving operator is incomplete. The system can be implemented in many different ways.

FIG. 5 shows a minimum system configuration. System 501 includes SIM card hardware 502 for use with SIM cards, user interface means 503, control means 504, and at least one radio receiver 505 and memory 506. User interface means 503 is adapted to display to the system user at least one unallocated temporary mobile station number 15 for receiving number and temporary mobile number. The control means 504 is adapted to receive, via the radio receiver 505, a set of short messages containing at least one short message addressed to the mobile number when the releasing operator's SIM card 20 containing that mobile number is inserted into the SIM card hardware 502. In addition, the control means 504 is adapted to retrieve '.' number and direct the received short message set to the temporary mobile * 'number.

Thus, short messages are routed via a multiplexer or similar equipment:. *. 25 to a temporary mobile number. Instead, the routing of calls and messages: v, such as MMS messages, is based on call forwarding. The present invention utilizes a call state model. and the intelligent network.

'· · ·' To describe the life cycle of a call from the beginning of an individual call to the end of the call, the call status model is used, where the • the call control function (CCF) transfers the call from one mode to another. If you want to respond to a call handled by the PBX, for example by providing a service, you must know the call status in real time.

•; · 'A BCSM (Basic Call State Model) state model has been created to identify call status. The BCSM defines call states that either detect 35 events or trigger predefined functions. In BCSM pu '. the status of the call is identified by a Detection Point (DP). A trigger and a trigger condition can be set on the 116351 g seal. When a call enters a state of a state model with a DP associated with a trigger and the trigger condition is true, that trigger is triggered. When the trigger is triggered, a predefined operation is performed.

5 The main idea of the Intelligent Network (IN) is to distinguish between call switching and call management, which allows for a flexible implementation of services. An intelligent network typically includes a single control point (SCP) and a plurality of switching points. A switching point, or SSP, is typically a digital telephone exchange capable of communicating with an SCP.

FIG. 6 shows an example of a system according to the invention wherein short messages are routed through multiplexer 601 to subscriber line 602 and where calls and / or messages are routed through SCP 603 to subscriber line 602. The subscriber line 602 operating in receiving network 604 includes a temporary telephone number. Initially, it is assumed that the subscriber interface 606 operating on the network 605 of the handover 15 is called to a mobile number to be ported. In a GSM network, this call is routed to the MSC (Mobile Switching Center) 607, which communicates with the HLR (Home Location Register) 608. HLR 608 contains call forwarding information. The call made from the subscriber interface 606 is then routed to GMSC (Gateway Mobile Switching Center) 20 609. Alternatively, the call is directed to the mobile number to be ported. . The 610 may come from outside the donor operator network 605. In this case, call 610 is routed directly to GMSC 609, which communicates with HLR 608. Thus, each call addressed to the mobile number to be forwarded to the GMSC 609 and, consequently, to the SSP 611 for call forwarding.

i 25 A trigger is set on the SSP so that a call triggers the trigger where;. the trigger condition is preferably a paging forwarding number. As the trigger is triggered, the call is routed to the SCP 603, which communicates with the MNP server 612. The MNP server 612 includes at least the user interface means 504, the control means 504, and: \: 30 memory 506 belonging to the system according to the invention. The connection between the mobile:] 3: message number and the temporary mobile number is stored in the MNP server memory. MNP server pa- [. transmits a temporary mobile number to the SCP which commands SSP 611 '; I; 'Direct the call to the receiving operator's network 604. The GMSC 613 of that network receives the call, communicates with the HLR 614, and directs the call to the MSC 615, through which the call ends in the subscriber interface 602.

FIG. 6 further illustrates the processing of short messages. The short message 616 assigned to the mobile number of mobile 116351 10 is received by a SIM card inserted in the multiplexer 601. More specifically, the received short message 616 is stored in the memory of the SIM card. The short message is then read from the SIM card memory and transmitted to the MNP server 601, which forwards it to the receiving operator SMSC (Short Message Service Center) 617. From the SMSC, the short message is routed to the GMSC 613 and the HLR performed in the HLR 614. after the interrogation to MSC 615 and thence to the local loop 602.

In Figure 5, in addition to the minimum system configuration, the system may include an SSP that is adapted to direct a call to the SCP when the call in question has been redirected due to a call transfer to the SSP and then triggered by a preset trigger on the SSP.

In addition, the system may include an SCP adapted to deduce a temporary telephone number based on a mobile number included in the call record of the call and command the SSP to route the call to the temporary telephone number.

In addition, the system may include an MNP server 612 or equivalent server adapted to store the connection of the mobile number and the temporary number. To complete the porting, this server is configured to send, via the OTA system, 20 short messages containing an OTA update to a subscriber line containing a temporary telephone number.

<v, The following elaborates on some of the system 5 shown in Figure 6; details and alternative ways of doing things are presented.

The SCP 603 can be located either on a stand-alone computer or integrated with an SSP exchange. In the latter case, the SSP is referred to as 25 SSCP (Service Switching and Control Point). The utilization of the invention is: in principle independent of the SCP implementation mode.

···, SMSC 617 is responsible for transmitting and storing short messages. If the message is not received at the first attempt, SMSC will store the message and retry sending the message later. In addition, SMSC provides: 30 application interfaces through which third-party applications can use: ,,, · SMSC and provide services to application users. In general, everyone. /, SMSC has its own solution. An example is Nokia ;;; An SMSC application interface called CIMD (Computer Interface for Message Distribution). Another example is short message centers manufactured by Aldiscon · * ·., 35 with application interface UCP or SMPP.

11 116351 SMSC 617 is typically implemented as software running on a UNIX server. Depending on the make and model, a number of connection options are available for SMSC. Of the connection options, the Internet or TCP / IP connection is smooth to use. To avoid security risks to your Internet connection, you can use a 5 modem connection. Short messages can also be sent and received over slow modem connections, but there are problems with long switching times and the acquisition and maintenance of different types of modems in SMSC and its communication servers.

When the communication connection from the MNP server 612 to the SMSC 617 is established, the communication connection is used according to a specific protocol. For example, the Nokia CIMD Application Interface provides the following operations: 1) session start and user authentication, 2) session end, 3) (send short message to SMSC, 4) message status request, 5) receive message, 6) change password, and 7) cancellation of a sent message.

FIG. 7 shows an example of a system implementation.

Unlike this example, many system details can be implemented. It is assumed that the office of the receiving operator has a workstation 701, a multiplexer 702 and a mobile radio unit 703 operating as a radio part of the system. In addition, the mobile station is: .v connected by a connecting cable 706 to a multiplexer. The multiplexer has 16 modules. · · · *, Each with 16 SIM card slots. The workstation controls the multiplexer via a parallel cable 704. Specifically, the workstation connects each of the SIM cards inserted in the multiplexer · · ·: 25 through a connecting cable 706 to a mat-V mobile station 703. The SIM card is then able to receive short messages in its memory if they have been sent. A typical SIM card contains one ··· 'processor and different types of memory (ROM, RAM, EEPROM). The workstation reads the received short messages from the memory of the SIM card inserted in the multiplexer via the serial cable 705, the mobile station 703 and: 30 the connecting cable 706. Workstation: * * *: The station is also connected via a communication cable 707 to the Internet 708 so that it can forward its read short messages over the Internet to the SMSC 709. In addition, the workstation communicates over the Internet with MNP server 710 when the user using the workstation .

* »116351 12

An advantage of the system shown in Figure 6 is that the short messages transmitted to the subscriber interface 602 include the original sender's telephone number. Thus, the user of the subscriber interface 602 knows where the short message came from and can easily respond to the short message if necessary. Another advantage of the system is that the radio part coupled to the SIM card hardware, such as the multiplexer 601, can be effectively used to receive short messages, since the short messages are forwarded via the application interface 617 of SMSC. However, most short messages are such that they need to be acknowledged, which requires a radio part.

If necessary, short messages can be transmitted directly to the network of the receiving operator via one or more radio parts connected to the multiplexer. In other words, the aforementioned workstation 701 does not need to use the application interface 709 of SMSC. If the connection between the mobile number and the temporary telephone number is also stored in the workstation memory, the workstation does not need to communicate with the MNP server 701 in order to obtain that connection. Because the workstation is able to read the short message received by the SIM card, the workstation can also change the received short message. The short message contains the sender's number, the recipient's number, and the (verbal) message. The workstation can add the sender's number to the beginning of the message, so that the 20 subscribers know the origin of the short message. In another alternative, the workstation transmits received short messages transparently. In this case, in the short messages received by the subscriber, the sender number is the original sender, even though the short message is received in the mobile number to be ported and forwarded from the mobile number to the intermediate telephone number.

FIG. 8 illustrates a SIM card hardware constructed from mobile stations.

. '·. The SIM card hardware 801 includes a plurality of mobile stations, which in this example is twenty. Mobile stations such as mobile station 802 are attached,. , to a bracket 803 that can be hung on a wall. The rack has wiring 804; 30 for power supply. The mobile stations attached to the rack are continuously operational and receive at mobile number portability. addressed text messages. If wiring 804 was left out, mobile devices. batteries should be charged. Workstation 805 periodically reads "SIM cards" of mobile stations and retransmits any text messages that mobile stations • '- · 35 have received and stored on their SIM cards. Figure 8 assumes ·: ·· that the mobile stations and the workstation communicate wirelessly! Suppose the mobile station 802 has received a text message, the client 805 sends a command 806 over the Bluetooth connection to retransmit the received SMS message to a specific temporary telephone number.

The multiplexer requires less space than the SIM card hardware shown in Figure 8. However, the multiplexer is a very expensive investment, so the apparatus of Fig. 8 may be a suitable option due to its low cost. The price is particularly advantageous if the equipment is built from the disused 10 mobile stations.

The SIM card hardware (702, 801) is adapted to communicate with the workstation (701, 805) and vice versa. Further, the workstation is adapted to communicate with a server (612) storing the connection between the mobile number and the temporary number. Typically, at least 15 portions of memory 506 shown in Figure 5 are located on a server.

It will be apparent to one skilled in the art that the embodiments of the system of the invention are not limited to the embodiments described above. It is also clear that the possibilities of utilizing the method and system according to the invention are not limited to the GSM network, but both of them can be utilized, for example, in GPRS (General Packet Radio System), VLAN (Virtual Local Area Network) or third generation system.
