FIELD OF INVENTION
[0001] The present invention relates to mobile telephony system and in particular, it relates to network transition of mobile telephony system.
BACKGROUND OF THE INVENTION
[0002] A mobile device communicates in a mobile telephony network to send and receive radio signals. Today’s mobile telephony service provider offers a General Packet Radio Service (GPRS) along with voice-calling capability. The GPRS service provides subscribers the capability of exchanging data packets via the mobile device. While the GPRS exists in many areas, data transmission rates are typically low, and costs incurred by wireless network service providers to support this service remain high, making the GPRS expensive.
[0003] Wi-Fi technology allows the mobile devices to connect to Internet to and exchange data wirelessly using radio waves. The Wi-Fi alliance, (the organization that owns Wi-Fi term) defines Wi-Fi as any wireless Local Area Network (LAN) products that are based on Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard for mobile communication. Advances in the field of the Wi-Fi technology has resulted in the emergence of publicly accessible wireless access point (termed as “hotspot”). The hotspots are available at airports, train stations, restaurants, shopping malls, libraries and similar public places. The relatively low cost to implement and operate the wireless LAN, as well as the available high bandwidth (usually in excess of 10 Megabits/second) makes the wireless LAN an ideal access mechanism through which a user of the mobile device can exchange packets with a mobile telephony system. The wireless LAN offer the user a much higher Quality of Service (QoS) level in comparison to the QoS level offered in connection with the GPRS. Accordingly, there is a need to provide handoff to the mobile device for transition of network connection from the mobile telephony network to the wireless LAN when the mobile device is in proximity to the wireless access point.
[0004] There are several approaches provided for transition of the network connection in the mobile device between the mobile telephony network and the wireless LAN. In US7330448, the invention provides a technique for interworking the wireless LAN with the mobile telephony network to allow the user to switch between networks. In this approach, the mobile device accesses the Internet via the mobile telephony system. When the mobile device is in the radio range of the wireless access point, the mobile device sends a request to access a wireless router. Once the user initiates the communication with the wireless router, the user sends identity information to the wireless router. The user of the mobile device is authenticated based on the received identity information and the access will be provided to the user after successful authentication of the user. However, this approach is limited by the fact that there is no provision provided to detect the mobile device automatically in proximity of the wireless access point. Further, the identity information is sent to the wireless router manually to create a wireless LAN session session for the received identity information. Moreover, the invention does not disclose billing service for the wireless LAN usage by the mobile device.
[0005] In US 8023953, the invention relates to mapping wireless proximity identificator to subscriber identity for hotspot based wireless services for the mobile devices. In this approach, a hotspot access point (HAP) scans the hotspot environment for detecting the mobile device. After detecting the mobile device in the proximity of the HAP, the HAP sends a message to the mobile device for connecting to the wireless LAN. The HAP requests the mobile terminal to provide additional information, which includes mobile identity, user information, etc. for creating the wireless LAN session. However, this approach is limited by the fact that the HAP does not retrieve the mobile identity of the user automatically. Further, the user is provided with details to connect to the wireless LAN only after the user responds to the message with the additional information, which is usually a time-consuming process.
[0006] In light of the above discussion, there is a need for a system and method, which overcomes all the above stated problems.

[0009] In an embodiment, polling the plurality of mobile devices further includes detecting a location of the plurality of mobile devices in radio range of the wireless router.
[0010] In an embodiment, the user accessing the URL triggers a mobile application installed on the mobile device to send the mobile identity of the user to the wireless router.

The wireless access point is a device that allows the mobile device 120 to connect to a wired network using Wi-Fi technology. A hotspot is an application of the wireless access point, which enables the mobile device 120 to connect to the Internet. Examples of the mobile device 120 include, but are not limited to a laptop, a Smartphone, the PDA, and a tablet computer. Common public places where the hotspot can be set up include, but are not limited to airports, cafes, libraries, train stations, and restaurants. The wireless network platform 150 allows the mobile device 120 to connect to a network using the Wi-Fi technology. In context of the present invention, the plurality of mobile devices 120 and 140 are able to connect to the wireless router 160 to access the Internet, when the plurality of mobile devices 120 and 140 are in the radio range of the wireless router 160.
[0028] In addition, the system 100 includes a mobile telephony system 170. The mobile telephony system 170 provides a telecommunication service to the mobile device 120. The telecommunication service is a communication at a distance through electrical signals or electromagnetic waves. The mobile telephony system 170 offers the user 110 a wide variety of a telecommunication network. Examples of the telecommunication network include, but are not be limited to the GSM network, the GPRS network, the CDMA system, the EDGE, and the WCDMA.
[0029] The user 110 of the mobile device 120 is a subscriber of a mobile network operator availing the mobile telephony system 170 service. In an embodiment, the same mobile network operator who provides the mobile telephony system 170 to provide wireless local area network connections to the mobile device 120 sets up the wireless network platform 150. The wireless local area network connections are enabled when the mobile device 120 is in proximity to the wireless router 160.
[0030] The mobile telephony system 170 offers the subscriber a wireless communication service such as the GPRS to access the Internet. In context of the present invention, the mobile device 120 receives a wireless communication service to access the Internet via the mobile telephony system 170. The mobile telephony system 170 includes at least one radio node in the form of a Universal Mobile Telephone System (hereinafter UMTS) Node for providing the GPRS within a particular geographic area to the mobile device 120.
[0031] In an embodiment, the mobile telephony system 170 detects a location of the mobile device 120. In context of the present invention, the mobile device 120 accesses the Internet in a mobile telephony network. If the mobile device 120 is found in proximity to the wireless router 160, the mobile telephony system 170 sends access information to access the Internet in the wireless local area network. In context of the present invention, proximity defines the radio range of the wireless router 160. Since the user 110 of the mobile device 120 is the subscriber of the mobile telephony system 170 provided by the mobile network operator, the user 110 is authorized to access the wireless network platform 150. The mobile telephony system 170 is a part of a Base Station Controller (hereinafter BSC) of a telecommunication infrastructure. The details of the telecommunication infrastructure are described in the explanation of Figure 4.
[0032] Figure 2 illustrates a method 200 for establishing the Wi-Fi connection between the mobile device 120 and the wireless router 160, in accordance with various embodiments of the present invention. The method 200 initiates at step 210. At step 220, the mobile telephony network 170 polls the plurality of mobile devices 120 and 140. Polling refers to continuously checking the status of a program or a device by another program or device. In context of the present invention, polling means to check the status of the plurality of mobile devices 120 and 140, which are accessing the Internet in the mobile telephony network. Checking the status of the plurality of mobile devices 120 and 140 is to determine the plurality of mobile devices 120 and 140 in proximity to the wireless router 160.
[0033] In an embodiment, the mobile telephony system 170 polls the plurality of mobile devices 120 and 140 to track the location of the plurality of mobile devices 120 and 140. Since the wireless network platform 150 and the mobile telephony system 170 are the provisions of the same mobile network operator, the mobile telephony system 170 have location information of the wireless network platform 150. If the mobile device 120 of the plurality of mobile devices 120 and 140 are found in the same location of the wireless network platform 150, the mobile telephony system 170 sends the access information to access the Internet via the wireless router 160.
[0034] At step 230, the mobile telephony system 170 identifies the mobile device 120 in proximity to the wireless router 160. The mobile telephony system 150 retrieves the polling status of the plurality of mobile devices 120 and 140. In addition, the mobile telephony system 170 retrieves the location information of the plurality of mobile devices 120 and 140 and the wireless network platform 150 from the mobile network operator. As mentioned above, based on the retrieved information, the mobile telephony system 170 identifies at least one mobile device 120 of the plurality of mobile devices 120 and 140 in proximity to the wireless router 160.
[0035] At step 240, the mobile telephony system 170 sends a message to the mobile device 120. In an embodiment, the message includes a Uniform Resource Locator (herein after URL) to access the Internet via the wireless router 160. In another embodiment, the message includes additional information to access the Internet via the wireless router 160.
[0036] At step 250, the mobile telephony system 170 receives mobile identity of the user 110 via the wireless router 160. In an embodiment, the user 110 clicks on the URL sent through the message to access the wireless router 160. Accessing the URL triggers a mobile application installed in the mobile device 120 to send the mobile identity of the user 110 to the wireless router 160.
[0037] In context of the present invention, the mobile identity relates to a digital identity provided via the mobile device 120 and a communication network. In an embodiment, the mobile identity relates to a digital signature. In another embodiment, a subscriber identification module (hereinafter SIM) card holds the digital signature of the user 110. In order to use the digital signature, the user 110 has to enter a personal secret code. Then, the mobile device 120 verifies the entered personal secret code and allows access to the digital signature of the user 110, stored on the SIM card. Examples of the user 110 include, but are not limited to a person, a subscriber of the wireless network, an owner of the Wi-Fi network, and relatives of the owner of Wi-Fi network. In yet another embodiment, a mobile digital signature application is present on the mobile device 120. The mobile digital signature application on the mobile device 120 receives the digital signature from a security server upon the registration of the mobile device 120 for creation of the mobile identity.
[0038] In another embodiment, the mobile identity is an identity code unique to the mobile device 120. Examples of the identity code include, but are not limited to an International Mobile Subscriber Identity (IMSI), a Mobile Subscriber Integrated Services Digital Network (MSISDN) number of the mobile device 120. In another example, a key generator present on the mobile device 120 generates the identity code. The identity code is used to identify the mobile device 120.
[0039] In yet another embodiment, the mobile identity relates to biometric signatures and digital signatures. The user 110 scans the user 110’s thumbprint on the mobile device 120. The mobile device 120 generates and transmits a response containing the digital signature of the user 110 and the scanned thumbprint. The digital signature is stored on the SIM card or on the mobile device 120. Additional details of the mobile identity are described in the detailed description of the Figure 5.
[0040] The wireless router 160 sends the received mobile identity of the user 110 to the mobile telephony system 170. At step 250, the mobile device 120 switches the network connection from the mobile telephony network to the wireless local area network to avail benefits of the wireless local area network.
[0041] At step 260, the mobile telephony system 170 creates a wireless LAN session associated with the received mobile identity of the user 110. The wireless session creation is to summarize an Internet usage by the mobile device 120 in the wireless local area network. In an embodiment, the Internet usage includes size of data downloaded by the user 110 on the mobile device 120 in the radio range of the wireless router 160. In another embodiment, the Internet usage includes total time taken by the wireless LAN session in the radio range of the wireless router 160.
[0042] At step 270, the mobile telephony system 170 establishes the Wi-Fi connection between the mobile device 120 and the wireless router 160. On creating the wireless LAN session as explained above, one or more processors in the mobile telephony system 170 establishes the Wi-Fi connection between the mobile device 120 and the wireless router 160 to access the Internet via the wireless router 160. Once the Wi-Fi connection is established between the mobile device 120 and the wireless router 160, the user 110 accesses the Internet via the wireless router 160 in the mobile telephony system 170.
[0043] Further, on establishing the Wi-Fi connection between the mobile device 120 and the wireless router 160, the mobile telephony system 170 calculates the Internet usage charges accessed by the mobile device 120. The mobile network operator can bill the user 110 on termination of the wireless LAN session. The mobile network operator sends billing details to the user 110 by retrieving the user 110 details from the received mobile identity of the user 110. At step 280, the method 200 terminates.
[0044] To better appreciate the technique of the present principles, the method by which the mobile device 120 switch from the wireless telephony network to the wireless local area network will be first described in detail below. Thereafter, the process by which the mobile terminal user switches from the wireless local area network to the wireless telephony network is described.
[0045] Transition from the mobile telephony network to the wireless local area network:
[0046] The mobile telephony system 170 polls the plurality of mobile devices 120 and 140 accessing the Internet in the mobile telephony network. The mobile telephony system 170 identifies at least one mobile device 120 of the plurality of mobile devices 120 and 140. The mobile telephony system 170 sends the message to the identified mobile device 120 on the mobile device 120 entering the coverage area of the wireless network platform 150. The message sent to the mobile device 120 includes the URL for accessing the Internet via the wireless router 160 in the wireless local area network. On user accessing the URL, the URL triggers the mobile application installed in the mobile device 120 for transmitting the mobile identity of the user 110. The mobile identity is sent to the wireless router 160. The wireless router 160 transmits the mobile identity to the mobile telephony system 170. On receiving the mobile identity of the user 110, the mobile telephony system 170 creates the wireless LAN session associating with the mobile identity. On creation of the wireless LAN session, the mobile telephony system 170 establishes the Wi-Fi connection between the mobile device 120 and the wireless router 160 for accessing the Internet in the wireless local area network. The transition of network from the mobile telephony network to the wireless local area network occurred on the mobile device 120 on establishing the Wi-Fi connection. On termination of the wireless LAN session, the mobile telephony system 170 calculates the Internet usage charges accessed by the mobile device 120. In an embodiment, the termination of the wireless LAN session includes the mobile device 120 exiting from the coverage of the wireless router 160.
[0047] Transition from the wireless local area network to the mobile telephony network:
[0048] Once the mobile device 120 exits the coverage area of the wireless router 160, the wireless LAN session terminates. On detecting movement of the user 110 of the mobile device 120 out of the wireless router 160 coverage area, the mobile device 120 is unable to connect to the wireless router 160 to access the Internet. On termination of the wireless LAN session, the user 110 of the mobile device 120 accesses the Internet from the mobile telephony network which was established previously. At this phase, transition of network connection occurred in the mobile device 120 from the wireless local area network to the mobile telephony network.
[0049] If the user 110 of the mobile device 120 enters the same coverage area on a subsequent visit, new wireless LAN session will be created following the same method as explained above for establishing the Wi-Fi connection between the mobile device 110 and the wireless router 160.
[0050] Figure 3 illustrates a block diagram 300 of a mobile telephony system 310 for establishing the Wi-Fi connection between the mobile device 120 and the wireless router 160. The mobile telephony system 310 is same as the mobile telephony system 170 explained in the detailed description of the Figure 1. The mobile telephony system 170 includes a polling module 320, a transmitter 330, a receiver 340, and one or more processors 350.
[0051] The polling module 320 polls the plurality of mobile devices 120 and 140 for identifying at least one mobile device 120 in proximity to the wireless router 160 as explained at step 230. The polling module functions are explained at step 220 of Figure 2. The transmitter 330 is functionally coupled to the polling module 320. On identifying at least one mobile device 120 from the polling module 320, the transmitter 330 transmits the message to the identified mobile device 120 for providing access to the Internet. The function of the transmitter 330 is explained at step 240 of Figure 2. The transmitted message to the mobile device 120 includes the URL for providing access to the Internet.
[0052] Further, on transmitting the message to the mobile device 120, the receiver 340 receives the mobile identity of the user 110. The mobile identity of the user 110 is received via the wireless router 160. When the user 110 clicks on the URL sent via the message to access the Internet, the mobile identity is transmitted to the wireless router 160. In an embodiment, the wireless router 160 is configured to receive the mobile identity of the user 110 and to transmit the received mobile identity to the mobile telephony system 170. As explained above, the user 110 clicks on the URL sent to the mobile device 120. The URL triggers the mobile application installed in the mobile device 120 for transmitting the mobile identity to the wireless router 160. The description of the mobile identity is explained above in the detailed description of Figure 2.
[0053] Furthermore, on receiving the mobile identity of the user 110, the one or more processors 350 are configured to create the wireless LAN session for providing access to the Internet via the wireless router 160. As explained above, the wireless LAN session helps in summarizing the Internet usage and billing the user 110 based on the Internet usage. In addition, the one or more processors 350 are configured to establish the Wi-Fi connection between the mobile device 120 and the wireless router 160. As explained above, on establishing the Wi-Fi connection, the mobile device 120 accesses the Internet via the wireless router 160 in the wireless local area network. The functions of the one or more processors 350 are explained in detail in the detailed description of the Figure 2.
