Definitions

  • the present invention relates to improvements in or relating to calling and called name presentation.
  • CNAP calling name presentation
  • This service deals with the retrieval, storage and delivery of a calling subscriber's name or other information during a call setup. Typically this information is retrieved from a name database (NADB) which is external to the network.
  • NADB name database
  • the CNAP service is relevant to at least GSM, WCDMA, circuit switched (CS) and packet switched (PS) networks.
  • Figure 1 shows an example of how calling name is retrieved from an external name database 100 during a communication between the calling mobile 102 and a called mobile 104 so that the calling name of the calling mobile can be displayed to the called mobile.
  • the calling name information is retrieved during the call setup by the originating node 106, a transiting node 108 or the terminating node 110. Wherever the request for the name information originates is an extra signalling load in order to request and deliver the name information from the database 100.
  • ANSI TCAP American standards Institute, Transactions Capability Applications Part
  • ISUP ISDN (Integrated Systems Digital Network) user part.
  • the calling party name is included in the ISUP IAM message in the generic name parameter, by the originating exchange.
  • the calling party name is not included in the ISUP IAM message and the terminating exchange obtains the name from an external database.
  • the retrieval method is not specifically specified in the standard, however the service is a required service and needs to be addressed.
  • the above described methods of name retrieval during the call setup stage have a number of disadvantages. This can include a delay in the call setup phase when the originating or transit node retrieves the name string from an external node during call setup. It is particularly disadvantageous for emergency calls. In addition there is significant increase in signalling traffic during the call setup phase when requesting and answering each name query made to or from the external node.
  • one object of the present invention is to provide a solution to at least some of the problems associated with the prior art in respect of mobile networks.
  • VLR Visitor Location Register
  • An advantage of this invention is that calling or connected name or other relevant information is made available with the minimum amount of processing requirements and signalling effort. Not only can calling name string be retrieved but also connected name, pictures, text, sounds, and other data.
  • VLR Visitor Location Register
  • By storing personal information at the Visitor Location Register (VLR) where the user is located enables considerably more flexibility than would have been the case with the prior art.
  • the name string (or other information) stored in the VLR would be available for additional future services such as intelligent networks and IMS services that may make to use of this information.
  • an apparatus for controlling the presentation of user information from a first user to a second user wherein the first and second users are connected to a wireless network having at least one network node for each user, the apparatus comprising at a network node to which a first user is connected:
  • an access unit for retrieving and storing user information from a database during a location update (LU) process for the first user
  • a processing unit for transmitting the stored user information to a second node to which the second user is connected for presentation of the user information to the second user.
  • Figure 1 is a block diagram showing a call name presentation process in accordance with the prior art.
  • FIG. 2 is a block diagram of a call name retrieving system according to one embodiment of the present invention.
  • Figure 3 is a diagram of a first node in the system of figure 2 according to one embodiment of the present invention.
  • Figure 4 is a diagram of a second node in the system of figure 2 according to one embodiment of the present invention.
  • Figure 5 is a flow diagram of the methods steps according to one embodiment of the present invention.
  • Figure 6 is a signalling diagram to demonstrate a method of signalling according to one embodiment of the present invention.
  • the calling name presentation (CNAP) feature enables the called party who has subscribed to the CNAP supplementary service to see the calling party's name on the terminal display.
  • the calling name is fetched during call setup from a database and then delivered to the called terminal. It is a purpose of this invention to enhance the existing CNAP feature to retrieve the name of the calling subscriber in a manner that reduces the signalling effort.
  • MSC mobile originating mobile switching centre
  • VLR visitor location register
  • this principle need not be limited to storage and retrieval of the calling name string only, but could be also used for pictures, text, sounds and other data.
  • the method supports the delivery of the connected name (possibly including pictures text etc) to the originating terminal as well.
  • a subscriber (A) is using a calling mobile 200 to call a called mobile 202 of the subscriber (B.).
  • the A subscriber is connected to a mobile switching centre (MSC) 204 which is in contact with a visitor location register (VLR) 206.
  • the visitor location register is connected by any appropriate means to the home location register (HLR) 208 of subscriber A and the name database (NADB) 210.
  • the call from subscriber A to subscriber B is made via the gateway mobile switching centre (GMSC) 212.
  • the GMSC is in contact with the MSCA/LR of subscriber B 214 and the home location register (HLR) of subscriber B 216.
  • the HLR is also in contact with the MSCA/LR and the MSCA/LR is in contact with the name database.
  • the calling name is retrieved and located in the visitor location register (VLR) 206 during the location update process.
  • Other information or subscriber data may also be retrieved at the same time, for example pictures, text, sounds, video, etc. the name string that is retrieved, could be received from either the external name database 210 or from the home location register serving the calling subscriber 208.
  • This first case would require a new interface between the VLR 206 and the external name database 210.
  • This second case would require changes to the mobile application parts (MAP) procedure "insert subscriber data (ISD)", in order to support the delivery of the name string to the VLR during location update.
  • MAP mobile application parts
  • ISD insert subscriber data
  • the second case, where the name information is stored in their home location register is the preferred of the two options, as it has additional benefits in providing name information to the GMSC, as will be described in greater detail below.
  • the name string is stored in the serving VLR as long as the calling subscriber is connected to that VLR.
  • the name string can be refreshed periodically as defined by either the VLR or the subscriber.
  • the new visitor location register it will be necessary for the new visitor location register to fetch the name data or other information as may be the case. This can be carried out during the first location update after the handover procedure has been carried out between the old and new visitor location register.
  • the mobile switching centre which is connected to a particular visitor location register can convert the name string into an ISUP parameter, which is called "Generic Name” (GN). If this generic name information is not required by certain nodes or networks, it can be screened out by the mobile switching centre or one of the nodes en route to the final destination during the call setup process.
  • G Generic Name
  • the GMSC or the terminating MSC will be required to execute an information query to determine the calling name information.
  • the query from the GMSC will be carried out as follows:
  • the GMSC sends the calling party number while sending "send routing info" to the HLR; • if the calling subscriber belongs to the same HLR, and the HLR has calling party name, the HLR will send the name in the "send routing info Ack" message.
  • the GMSC will be able to retrieve calling name information without requiring any additional query, thereby reducing signalling.
  • the GMSC will not get the name from the HLR and in these situations it will be the terminating MSC that will carry out the query. The amount of signalling that this will require is considerably less than in current procedures.
  • the invention thus provides a system and a method by which calling name (or other information objects) could be stored in the VLR after the location update has occurred.
  • the information could be used for several purposes, including the calling name presentation feature or other features like intelligent network or IP multimedia services.
  • the calling name would be available with considerably reduced signalling effort.
  • the calling name or other information is stored in the HLR the only requirement is an additional parameter to be sent from the HLR to the VLR during the location update interface (MAP, ISD procedure).
  • the information may be stored in a database on the VLR node.
  • the names string stored in the VLR would be available for additional future services such as intelligent network services and IP Multimedia Subsystem (IMS) services that make use of the name information. Additional information may also be stored in the VLR as previously indicated, such as pictures, sounds, logos, text etc so that they are available if required.
  • IMS IP Multimedia Subsystem
  • FIG 3 shows the node of the network corresponding to the VLR 206 in figure 2.
  • the calling mobile 300 makes a wireless connection with the VLR 302.
  • the VLR may contact the HLR of the calling mobile and/or the name database (NADB) during the location update process in order to retrieve calling name information.
  • This information relating to calling name is then transmitted via, for example, the GMSC to the called mobile at a visitor location register or a home location register as the case may be.
  • NADB name database
  • figure 4 shows the node of the network of the called mobile that corresponds to the B-MSCA/LR 214 in figure 2.
  • so-called mobile 400 is connected to an MSCA/LR 402 in the vicinity of the called mobile.
  • This node receives calling name information via any appropriate node in the network, for example the GMSC.
  • this node can retrieve name information subsequently becoming connected name information from either the home location register of the called mobile or the name database as the case may be and as will be described in greater detail below with reference to figure 6.
  • the mobile performs a location update at step 5001.
  • the VLR then proceeds to retrieve a name associated with the mobile from any appropriate location, including for example the HLR of the calling mobile or the name database of the network. This is shown in step 504.
  • the VLR then stores the name at an appropriate location; step 506. This name is stored at this location until the mobile moves out of range of that particular VLR. It may be necessary to periodically update or reacquire the data of the name if it is lost for any reason; step 508. If the mobile moves out of the range of the particular VLR the name information may be transferred during the transfer processes as described elsewhere.
  • the mobile initiates a first call at step 500.
  • the previously retrieved name associated with the calling mobile station is now to be considered the calling name.
  • the VLR in the vicinity of the calling mobile receives the call request from the calling mobile; step 502.
  • the VLR then proceeds to send the call to the terminating node via any appropriate route through the network including the calling name with the call; step 510.
  • the call ends; step 512.
  • the calling mobile may make a subsequent call at step 514, however in this situation it may not be necessary for the VLR to retrieve the calling name information as this is already there from the first call.
  • step 510 the call is sent to the terminating node of the new call and the call includes the calling name information which is already stored. If for any reason the calling name information is not available a subsequent call may proceed with the retrieval of the calling name corresponding to step 504.
  • the called name ie the name of the subscriber that is being called, and may be of interest to the calling subscriber.
  • This feature could be referred to as "connected name presentation (CONP)" and work in a similar manner to CNAP. Further details of the CONP will now be described.
  • the name information is stored during location update in the VLR.
  • the name information thus becoming connected name information is forwarded to the originating MSC in the opposite direction to the call.
  • the MSC may then relay the information relating to connected name to the calling user terminal.
  • the vertical lines represent a node in the network and the horizontal lines represent messages between respective nodes.
  • the three nodes are the mobile subscriber 600, the originating MSC (O-MSC) 602, and the terminating MSC (T-MSC) 604.
  • the steps carried out in order to implement connected name presentation start with a Connection Management (CM) service request from the mobile subscriber to the originating MSC.
  • CM Connection Management
  • the originating MSC replies with a CM service accept message and in turn the mobile subscriber sends a call setup message to the originating MSC.
  • the originating MSC confirms that the call is proceeding to the mobile subscriber and sends an ISUP IAM message to the terminating MSC.
  • the connected name information (or any other appropriate information) is then sent with one of the ISUP return messages, for example in the Address Complete Message (ACM), Answer Message (ANM) or Connect Message (CON).
  • ACM Address Complete Message
  • ANM Answer Message
  • CON Connect Message
  • the connected name presentation is then transferred to the user with the Direct Transfer Application Path (DTAP) facility information elements included in an alerting or connect message or a similar message.
  • the connected name presentation could be restricted by the subscriber using a connected name presentation restriction (CONR).
  • CONR connected name presentation restriction
