`LOCATION INFORMATION SERVICE FOR A
`CELLULAR TELECOMMUNICATIONS
`NETWORK
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`This invention relates to a location information service for
`a cellular telecommunications network, which enables indi
`vidual mobile stations to receive information about their
`location within the network.
`2. Description of the Prior Art
`A number of proposals have been made to locate the
`position of mobile stations within a cellular telecommuni
`cations network. Each cell of the network corresponds to a
`particular geographical area and the cells are provided with
`individual identi?cation codes. Thus, when a mobile station
`communicates through a particular cell, a rough estimate of
`its geographical location can be obtained using the cell
`identity. In urban situations, the cells may have an approxi
`mate diameter of the order of 200 meters.
`A number of methods have been proposed to improve the
`locational accuracy. For example, the timing advance used
`in communications between the mobile station and the
`transmitter for the cell, can be monitored to determine
`whether the mobile station is relatively near to or far away
`from the transmitter. Also, schemes have been proposed to
`introduce an angular resolution around the transmitter. Other
`schemes involve a triangulation method using transmissions
`received from adjacent cells.
`A location ?nding service is being offered commercially
`by Cell Point Systems AB of Kista, Sweden and reference is
`directed to W0 01/ 31966. The system is marketed under the
`name FinderTM. Groups of subscribers can ?nd out the
`location of members of the group from a mobile telephone.
`The user starts by de?ning a list of friends that they want to
`be able to locate, be seen by or communicate with. This
`involves a pre-registration procedure with the vendor of the
`Finder service. When a user wants to know the location of
`a friend, colleague or family member, the user initiates a
`request through their mobile telephone or computer and
`selects a name or names. The Finder system then locates
`both the user and the friend and calculates the distance and
`direction to the friend. The result is communicated back to
`the user as a text message.
`A disadvantage of this system is that the user needs to
`pre-register with the system and only has access to the
`location of members of the relevant group.
`
`SUMMARY OF THE INVENTION
`
`20
`
`25
`
`30
`
`35
`
`40
`
`45
`
`50
`
`The invention provides a location information service for
`mobile stations in a cellular telecommunications network
`that is provided independently of an aforesaid vendor. A
`request for location information may be sent from a mobile
`55
`station as a short message (SMS) through the network to a
`location message server with an associated data store that
`contains location information based on the cells of the
`network. Location information based on the cell occupied by
`at least one mobile station is derived from the data store and
`sent through the network from the location message server
`as a SMS to the mobile station that requested the informa
`tion. According to the invention, the service is provided
`without requiring pre-registration of the subscriber that uses
`the mobile station.
`Thus, in accordance with the present invention, there is no
`need to form pre-registered groups of users and each indi
`
`65
`
`60
`
`2
`vidual mobile station can make use of the location informa
`tion service without having to pre-register.
`The request from the mobile station may be for informa
`tion concerning its own location, in which case the retrieved
`data is sent to the mobile station that made the request.
`Alternatively, the request may be for data concerning the
`location of another mobile station, in which case, data is
`retrieved from the data store based on the cell occupied by
`the other mobile station, and the retrieved data is sent to the
`mobile station that made the request. A check may be carried
`out to determine whether the other mobile station permits
`data concerning its location to be sent to others in order to
`provide privacy, if required.
`Instead of retrieving the data from the data store, the other
`mobile station may itself provide the data concerning its
`location to the mobile station that made the request.
`In another aspect, the invention provides a method of
`providing privacy in a location information service to
`mobile stations in a cellular telecommunications network. In
`a ?rst mode, the invention includes sending a request for
`location information from a mobile station as a message
`through the network to a location message server, deriving
`location information based on the location of at least one
`mobile station, sending the location information to a third
`party application, using the third party application to
`develop data based on the location information, and sending
`the data through the network from the location message
`server as a message to the mobile station that requested the
`information. In a second mode, the invention includes
`inhibiting data from the third party application being sent, in
`response to a privacy request from said at least one mobile
`station.

`
`DETAILED DESCRIPTION OF THE
`INVENTION
`
`FIG. 1 illustrates a public land mobile network PLMNl
`that provides a cellular mobile telecommunication service to
`mobile stations in the form of mobile handsets MS1, MS2.
`The PLMNl may be of any of the well known types such as
`GSM, DAMPS or UMTS and in the following description,
`a GSM network is described by way of example. The
`
`Apple Inc. Exhibit 1001 Page 6
`
`

`
`US 7,072,667 B2
`
`3
`network is shown schematically that includes base transmit
`ter stations BTS1, BTS2 which, as illustrated provide a radio
`link to the handsets MS1, MS2. PLMN 1 also includes base
`station controllers, mobile switching centers and a home
`location register as well known in the art. These features are
`not illustrated in the drawing and since they are very well
`known, will not be described further herein.
`GSM networks support a short message service (SMS) by
`which text messages can be communicated between mobile
`stations, in addition to the usual speech communication. In
`accordance with the invention, a SMS message center
`(SMSC) 10 is connected to the PLMN1 to process SMS
`messages concerning location requests and responses, as
`will be explained hereinafter. The SMSC 10 is connected to
`a location messaging server 11 with an associated location
`database 12.
`Referring to FIG. 2, the con?guration of an individual cell
`associated with the base station controller BTS1 is shown
`schematically. The transmitter BTS1 has a usable range
`illustrated schematically by hatched outline 13. Thus, if the
`handset MS1 is communicating over a radio link with the
`network through BTS1, it is within the circular area 13 of the
`cell associated with BTS1. In accordance with the GSM
`Recommendations, each cell has an individual identity
`known to the network. In this example, the cell shown in
`FIG. 2 has a cell identity C1. Thus, when the handset MS1
`communicates with BTS1, the cell identity corresponds to a
`rough geographical location for the handset. Typically, in
`urban situations, the cell 13 has a radius of 100 meters. The
`actual cell siZe depends upon the con?guration of the
`network and as well known in the art, the cellular dimen
`sions are made smaller in regions of high population density
`and larger in rural areas. As shown in FIG. 2, a distinctive
`landmark in the form of a church 14iSt. Mark’s Churchi
`is located within the cellular area 13.
`In accordance with the invention, the user of handset MS1
`can send a request to the landmark location messaging
`server 11 to obtain details of local landmarks in the form of
`a SMS. This process will now be described in more detail
`with reference to FIG. 3.
`At step 83.1, the mobile station MS1 sends a request 15
`in the form of a SMS over the radio link to BTS1 to the
`network PLMN 1 and thence to the SMSC 10 at step 83.2,
`as request 16. The request 15 contains the telephone number
`(MISDN) of MS1 together with category data D1, D2 or D3
`discussed in more detail below. The request 16 contains the
`data from request 15 and the cell identity; cell C1 in this
`example, obtained from the network PLMN 1.
`The SMSC 10 refers the request to the location messaging
`server 11 which refers to the database 12 in order to fetch
`stored data corresponding to the cell concerned, namely cell
`C1. The data in the database 12 may be arranged as shown
`in Table l, in which landmark data corresponding to indi
`vidual cells is stored, together with other data relevant to the
`cells such as local restaurants, railway stations and the like.

`
`At step 83.4, the location server provides relevant data 18
`to the SMSC 10 in response to the location request. For
`
`60
`
`65
`
`4
`example, if the user of MS1 has requested landmark data D1,
`a message such as “St. Marks Church is nearby” is provided
`to indicate that church 15 is within cell 13. Alternatively, if
`the user has requested information D2 about railway sta
`tions, data “Newtown Station” may be provided. Further, if
`information D3 regarding restaurants has been requested,
`appropriate restaurant data may be supplied.
`The SMSC 10 then creates a SMS text message 19
`containing the retrieved data from the location messaging
`server 11. The resulting SMS is sent at step 83.5 to PLMNl
`and thence as SMS message 20 to the MSISDN of MS1 to
`be received by MS1, as shown at step 83.6. The short
`message can be then displayed by MS1 and if appropriate
`stored therein for future use.
`FIG. 4 illustrates an alternative process by which the user
`of mobile station MS1 obtains information concerning the
`location of mobile station MS2. At step 84.1 a request 21 is
`sent by mobile station MS1 to the network PLMNl, to be
`routed at step 84.2 as request 22 to SMSC 10. The requests
`21 contain the MSISDNs of MS1 and MS2 together with the
`data D1, D2 or D3 concerning the requested category of data
`i.e. landmark data or other data such as railway stations or
`restaurants relevant to the location of mobile station MS2.
`At step $4.2, reference is made to the network in order to
`determine the identity of the cell currently occupied by
`mobile station MS2. This is incorporated into the request
`sent as request 22 to SMSC 10.
`Then, at step S43, SMSC 10 sends a request 23 to the
`PLMN 1 that is routed to mobile station MS2, as request 24,
`at step 84.4, in order to determine whether the user of MS2
`is content to allow its positional information to be commu
`nicated to others. If MS2 is happy to release this informa
`tion, a response 25 is sent at step 84.5, to the PLMNl and
`forwarded as response 25 to SMSC 10 at step 846.
`Having received clearance from MS2, the SMSC 10 at
`step S47, refers a request 27 to the location messaging
`server 11 in order to obtain landmark or other data pertinent
`to the cell occupied by MS2, which is returned as message
`28 to SMSC 10, at step 84.8.
`The SMSC 10 at step 4.9 assembles a SMS message 29
`containing the fetched data, which is then sent to network
`PLMNl and forwarded at step $4.10 as message 30 to be
`received by the mobile station MS1. The resulting data is
`displayed by MS1 to the user thus providing information
`about the location of MS2 to the user of MS1.
`FIG. 5 illustrates the process when the user of MS2 does
`not wish its location information to be made available to
`others. When MS1 requests data concerning MS2, request
`21 is sent at step 85.1, as previously described with refer
`ence to FIG. 4 and is sent as request 22 to SMSC 10. Then
`as described with reference to FIG. 4, requests 23 and 24 are
`sent to MS2, at steps S53 and 85.4, in order to request
`whether MS2 is prepared to release its positional informa
`tion to others. At step S55, MS2 sends message 31 indi
`cating that it is not prepared to release its positional infor
`mation to others, and this message is transferred at step 85.6,
`as message 32, to the SMSC 10.
`The SMSC 10 then does not refer to the location mes
`saging server 11 but instead sends message 33 at step 85.7
`to the PLMNl, to be transferred at step 85.8 as message 34
`to the mobile station MS1. Message 34 comprises a SMS
`notifying the user of MS1 that data concerning the location
`of MS2 is not available.
`In another modi?cation shown in FIG. 6, MS1 is provided
`with positional information concerning MS2 derived from
`MS2 rather than the location messaging server 11. At step
`S61, MS1 sends an SMS message 35 to the network
`
`Apple Inc. Exhibit 1001 Page 7
`
`

`
`US 7,072,667 B2
`
`5
`PLMNl containing the MSISDN of MS1 together With the
`MSISDN of MS2. At step 86.2 a message 36 containing the
`data from message 35 together With positional information
`concerning the cell occupied by MS2, is transmitted as SMS
`message 36 to SMSC 10. Then, at step $6.3 SMSC 10 routes
`a request message 37 to PLMNl Which in turn, at step $6.4
`routes the message as message 38 to MS2.
`At step $6.5, MS2 may decide to provide positional
`information from its oWn memory to MS1, in response to the
`request 38. For example, as previously described With
`reference to FIG. 3, the message 20 may be stored in the
`memory of MS1 for subsequent re-use. Alternatively, the
`stored message 20 may be modi?ed by the user to provide
`more precise or personalised location information. The
`resulting positional information is transmitted as SMS 39 to
`PLMNl and then at step 86.6 is sent as message 40 to
`SMSC10.
`At step 86.7, the SMSC 10 develops an SMS message
`containing the data received from MS2 about its location.
`The resulting message 41 is transmitted through PLMN1
`and then, as step 86.8 to MS1, as SMS 42 to be displayed
`by the user of MS1.
`It Will be understood that With the described system, there
`is no need to pre-register With the location service that may
`be provided free of charge by the netWork operator, or at the
`usual tariff for SMS messages.
`The system provides information about any mobile sta
`tion currently using the netWork, Without the requirement to
`form groups of “friends” or other group identities. Further
`more, privacy is assured for individual users Who do not
`Wish to release their location information to others. Many
`modi?cations and variations fall Within the scope of the
`invention. For example, more precise positional information
`may be achieved by the use of angular resolution Within
`individual cells or by monitoring the timing advance setting
`for the individual mobile station during transmission.
`Another embodiment of the invention is shoWn in FIG. 7.
`The arrangement is generally similar to that of FIG. 1 and
`the same reference numbers are used for corresponding
`components in the tWo Figures. The arrangement of FIG. 7
`has a position server 13 additionally shoWn, Which provides
`the positional data corresponding to the position of the
`mobile station(s). This can be based on the cell identity as
`previously described or may include other positional data
`that may be provided by the use of angular resolution Within
`individual cells or by monitoring the timing advance setting
`for the individual mobile station during transmission, or
`possibly GPS ?xes for the mobile stations, regularly updated
`to the server 13. This positional data is provided by the
`server 13 to the location messaging server 11 so that
`landmark messages can be supplied to the mobile stations in
`response to a request from the SMSC 10 as previously
`described.
`The location messaging server 11 may also supply the
`positional data from the server 13 and/or the landmark data
`from the store 12 to third party applications illustrated
`schematically as applications 14 and 15. These applications
`may be run on separate servers as shoWn or as applications
`on the server 11. The system normally operates in a ?rst
`mode Whereby third party applications provide additional
`information to the mobile stations based on their position.
`For example, the third party application 14 may compute a
`route to be folloWed When either Walking or travelling in a
`vehicle, in order to travel from the location of mobile station
`MS1 to MS2. This may be requested by MS1 in the manner
`
`40
`
`45
`
`20
`
`25
`
`30
`
`35
`
`50
`
`55
`
`60
`
`65
`
`6
`previously described, and the computed route is forWarded
`by the location messaging server 11 to MS1 as series of route
`directions in a SMS.
`Other third party applications are possible. For instance,
`When a mobile station requests particular landmark infor
`mation, merchants may Wish to provide advertising or other
`promotional messages to a mobile station that is provided
`With particular landmark data. Considering the example
`described With reference to FIGS. 1 and 2, Wong’s Chinese
`restaurant may Wish to send details of its special offers in
`response to a request from mobile stations for information
`about restaurants, that are provided With landmark data for
`St Mark’s Church that is nearby the restaurant. In this
`situation, third party application 15 develops data about the
`special offer and forWards the data to the server 11 so that it
`is forWarded to MS1 in a SMS.
`The system may be con?gured to operate in a second
`mode that ensures that the individual mobile stations are
`ensured privacy in respect of the third party applications. For
`example, if MS2 does not Want its location to be made
`available to third party application 13, for route computa
`tions, MS2 may block the transfer of its positional informa
`tion to the server 11, in the manner described With reference
`to FIG. 5. Similarly, if MS1 does not Wish to receive
`promotional information from third party application 15,
`MS1 may provide a privacy request message to the server
`11, in order to block the sending of promotional or like
`messages to it from server 15. Thus, privacy is assured for
`those individual users Who do not Wish to release their
`location information to others.
`It Will be understood that With the system described With
