Abstract
Description
Technology Field
[0001] The present invention relates to a method for providing a caller information display service and a communication system for performing the same. Background Technology
[0002] Conventionally, when a call was received, information about the caller was searched through the address book stored on the device or a separately installed app (e.g., WhoWho), and the matching information was displayed.
[0003] In this case, if information about the caller is not found, the recipient has no choice but to decide whether to connect with the caller based solely on the caller ID.
[0004] In addition, as a corporate lettering service available to corporate customers, BIZ Lettering displays the company's main phone number and caller information (e.g., company name, contact person name, etc.) on the recipient's mobile phone or internet phone when a company makes a call externally.
[0005] However, conventionally, the provision of lettering services is determined based on subscriber information, such as the caller ID. Therefore, if the caller ID is the same, the recipient is displayed with the company information to which the sender belongs, even if the sender has left the business premises.
[0006] Furthermore, from the perspective of corporate subscribers, the lettering service is limited to wired terminals connected to the company's private exchange upon call connection, or it is only available if subscriber information, such as caller IDs containing specific numbers, is registered in advance. The problem to be solved
[0007] Accordingly, the technical problem to be solved by the present invention is to provide a method for providing a caller information display service and a communication system for performing the same, wherein a plurality of dedicated networks providing service areas for a specific minority are managed based on a distinguishing element, and when a calling terminal requests a call connection through a dedicated network, lettering data mapped to the dedicated network connected to the calling terminal is included in the call connection request and provided to a receiving terminal. means of solving the problem
[0008] According to one feature of the present invention, a method for providing a caller information display service is a method in which a core network provides a caller information display service in a communication system comprising one or more wireless access networks and a core network, wherein the core network comprises the steps of receiving a call connection request through a wireless access network connected to a calling terminal, and transmitting lettering data mapped to the connected wireless access network to the calling connection request and transmitting it to a receiving terminal, wherein the lettering data included in the calling connection request is displayed as caller information on the call connection screen of the receiving terminal.
[0009] The above-mentioned transmitting step may include the step of verifying the identifier of the connected wireless access network, and the step of including lettering data mapped to the identifier in the call connection request and transmitting it to the receiving terminal.
[0010] Prior to the receiving step, the method further includes a step of mapping and storing lettering data for each identifier assigned to a plurality of different dedicated networks providing a service area for a specific minority, and
[0011] The step of transmitting to the receiving terminal includes, if the verified identifier indicates a previously registered dedicated network, the step of including lettering data mapped to the verified identifier in the call connection request and transmitting it, and if the verified identifier does not indicate the dedicated network, the step of transmitting the call connection request received from the sending terminal to the receiving terminal.
[0012] The receiving terminal may output a call connection screen including the lettering data or a call connection screen not including the lettering data, depending on whether the lettering data is included in the call connection request.
[0013] The above-mentioned storing step further comprises, prior to the step of storing lettering data and time information by mapping them for each of the above-mentioned identifiers and transmitting the lettering data by including it in the call connection request, a step of determining whether the identified identifier represents the dedicated network, and if it represents the dedicated network, a step of determining whether the time at which the call connection request was sent satisfies the time information mapped to the identified identifier.
[0014] The step of transmitting the lettering data by including it in the call connection request comprises, if the verified identifier indicates the dedicated network and satisfies the time information, transmitting the mapped lettering data by including it in the symbol connection request.
[0015] The step of transmitting a call connection request received from the sending terminal to the receiving terminal may transmit the call connection request received from the sending terminal to the receiving terminal if the verified identifier does not indicate the dedicated network or does not satisfy the mapped time information.
[0016] Each of the above lettering data may be business lettering data registered by a corporate subscriber of a business location where the above dedicated network is established.
[0017] The above identifier may include an APN (Access Point Name) or an ID.
[0018] The above-mentioned transmitting step may include: a step of requesting a clock-in / clock-out check confirmation of the sending terminal to a clock-in / clock-out check system; a step of, if it is determined that the person has clocked in, including lettering data mapped to the wireless access network connected to the sending terminal in the call connection request and transmitting it to the receiving terminal; and a step of, if it is determined that the person has not yet clocked in or has clocked out, transmitting a call connection request that does not include the mapped lettering data to the receiving terminal.
[0019] According to another feature of the present invention, a communication system comprises one or more wireless access networks and a core network, and includes a lettering database that maps and stores lettering data for each of one or more dedicated networks providing a service area for a specific minority, and a caller information display service providing unit that, when a call connection request is received through a wireless access network connected to a calling terminal, obtains lettering data mapped to the connected wireless access network from the lettering database, includes it in the call connection request, and transmits it to a receiving terminal.
[0020] The above lettering database stores lettering data by mapping it to each identifier assigned to a plurality of dedicated networks, and
[0021] The caller information display service provider verifies the identifier of the connected wireless access network, and if the verified identifier indicates a previously registered private network, includes lettering data mapped to the verified identifier in the call connection request, and if the verified identifier indicates a public network, transmits a call connection request excluding the lettering data to the receiving terminal.
[0022] When the receiving terminal receives a call connection request transmitted by a sending terminal connected to the dedicated network, it outputs a call connection screen including the mapped lettering data, and when it receives a call connection request transmitted by a sending terminal connected to the public network, it outputs a call connection screen not including the lettering data.
[0023] The above lettering database stores the respective lettering data and respective time information by mapping them according to the respective separator, and
[0024] The caller information display service provider can determine whether to include the mapped lettering data in the call connection request based on whether the identified identifier is the dedicated network and whether the time at which the call connection request was sent satisfies the time information mapped to the identified identifier.
[0025] The above lettering database and the above caller information display service provider can be implemented as core network entities.
[0026] The communication system may further include an application server comprising the lettering database and the caller information display service provider; a private network packet data network gateway (P-GW) that receives a call connection request through the private network and requests lettering data mapped to a identifier of the private network from the application server, and receives a call connection request containing the mapped lettering data and transmits it to the receiving terminal; a public network packet data network gateway (P-GW) that transmits a call connection request received through the public network to the receiving terminal; and a Mobile Management Entity (MME) or Serving Gateway (S-GW) that, when a call connection request is received through a wireless access network connected to the calling terminal, determines whether the wireless access network is the private network or not, transmits the call connection request to the private network packet data network gateway if it is the private network, and transmits the call connection request to the public network packet data network gateway if it is the public network. Effects of the invention
[0027] According to an embodiment of the present invention, the recipient can check approximate caller information even for caller numbers that cannot be searched using an address book or a separate app.
[0028] In addition, from the sender's perspective, lettering services can be provided to promote the company by registering corporate promotional images, etc., in the core network. Brief explanation of the drawing

[0035] Hereinafter, a method for providing a caller information display service according to an embodiment of the present invention and a communication system for performing the same will be described in detail with reference to the drawings.
[0036] Figure 1 shows the configuration of a communication system according to an embodiment of the present invention.
[0037] Referring to FIG. 1, the communication system includes a sending terminal (100), a receiving terminal (200), one or more wireless access networks (300, 400, 500) and a core network (600).
[0038] The sending terminal (100) is a terminal operated by the user making the call, and corresponds to a terminal capable of making a call to another party, such as a feature phone, smartphone, or PDA (Personal Digital Assistant). The receiving terminal (200) is a communication terminal capable of making a call to another party, similar to the sending terminal (100), and may consist of a feature phone, smartphone, PDA, etc.
[0039] One or more wireless access networks (300, 400, 500) are access networks that perform wireless communication with a transmitting terminal (100) and a receiving terminal (200), and each includes a base station (301, 401, 501). These one or more wireless access networks (300, 400, 500) have regionally separated service coverages and support data transmission and reception with a transmitting terminal (100) and a receiving terminal (200) located within said service coverage.
[0040] Here, one or more wireless access networks (300, 400, 500) are divided into a transmitting wireless access network (300, 400) and a receiving wireless access network (500).
[0041] The transmitting wireless access network (300, 400) includes a plurality of different private networks (300) that provide service areas for a specific minority and a public network (400) that provides to an unspecified majority. It may also include a private LTE network and a public LTE network.
[0042] Here, the private network (300) is managed by a private network base station (301) or a private P-GW (not shown) that covers a certain area having a predetermined service radius, and can be built at a company's business site. Due to characteristics such as security and a limited service range (network coverage), a private LTE network can be built by a company, etc., so that only authenticated employees or devices can access the network and use the service.
[0043] The dedicated network (300) may be included in the public network (400), but is distinguished separately from the public network (400).
[0044] When the transmitting terminal (100) is located in a dedicated network (300), it is connected to a dedicated network base station (301) and receives communication services through the dedicated network base station (301), and when it is located in a public network (400), it is connected to a public network base station (401) and receives communication services through the public network base station (401).
[0045] The receiving wireless access network (500) includes a base station (501) that provides communication services to the receiving terminal (200). At this time, the receiving wireless access network (500) may also include a dedicated network and a public network, but in the embodiment of the present invention, the receiving side is not distinguished as a dedicated network and a public network and is described as a receiving wireless access network.
[0046] The core network (600) connects one or more wireless access networks (300, 400, 500) or provides a connection with an external network.
[0047] The core network (600) stores information regarding the dedicated network (300) in advance. The core network (600) identifies the networks using a separator for one or more different dedicated networks (300). It then manages lettering data by mapping each separator. Here, the lettering data is information representing the caller, and the receiving terminal (200) outputs the lettering data after receiving a call connection request from the calling terminal (100) and before accepting the call connection request. The lettering data allows the user of the receiving terminal (200) to know in advance who the caller is who requested the call connection.
[0048] At this time, the core network (600) uses a separator to identify whether the wireless access network connected to the sending terminal (100) is a dedicated network (300), and if it is a dedicated network (300), provides lettering data mapped to the separator to the receiving terminal (200) to provide additional information that can identify the sender in addition to the sender number.
[0049] This lettering data may be business lettering data registered by a corporate subscriber of a business establishment where a dedicated network has been established. That is, it may include corporate information, corporate promotional information, etc. By doing so, the core network can distinguish each company or business establishment regarding the dedicated network (300) and make it possible to provide information about it.
[0050] When a sending terminal (100) is connected to a dedicated network (300) and is using a service, the core network (600) distinguishes the connection network of the sending terminal (100) and provides the receiving terminal (200) with the sender information, such as corporate or business location information or CI (Corporate Identity) image mapped to the connection network, i.e., the connected dedicated network (300), using CNAP (Calling Name Presentation) or URL, etc.
[0051] This core network (600) may include a configuration such as that of FIG. 2.
[0052] Figure 2 shows the configuration of a core network according to an embodiment of the present invention.
[0053] Referring to FIG. 2, the core network (600) includes a lettering database (601) and a caller information display service provider (603). These lettering database (601) and the caller information display service provider (603) can be implemented as core network entities.
[0054] The lettering database (601) stores lettering data by mapping each lettering data for one or more private networks (300) that provide service areas for a specific minority. At this time, lettering data is stored by mapping each lettering data for each identifier assigned to a plurality of private networks (300). That is, lettering data can be mapped for each private network identifier, and the lettering data can be corporate information. The private network identifier may include an Access Point Name (APN) or an ID.
[0055] Lettering data can be text files, still image files, video files, audio files, etc.
[0056] According to another embodiment, lettering data and time information for each separator of the dedicated network (300) can be mapped and stored. Here, the time information may be composed of a time range. The time information may be working hours.
[0057] When a caller information display service provider (603) receives a call connection request through a wireless access network connected to the sending terminal (100), it obtains lettering data mapped to the wireless access network connected to the sending terminal (100) from a lettering database (601). Then, it includes the obtained lettering data in the call connection request and transmits it to the receiving terminal (200).
[0058] The caller information display service provider (603) checks the identifier of the wireless access network connected to the sending terminal (100), and if the identified identifier indicates a previously registered private network, it includes lettering data mapped to the identified identifier in the call connection request. Then, if the identified identifier indicates a public network, it transmits a call connection request without lettering data to the receiving terminal (200).
[0059] Then, when the receiving terminal (200) receives a call connection request transmitted by the sending terminal (100) connected to the dedicated network (300), it outputs a call connection screen including lettering data mapped to the dedicated network (300). On the other hand, when the receiving terminal (200) receives a call connection request transmitted by the sending terminal (100) connected to the public network (400), it outputs a call connection screen that does not include lettering data. Of course, even if lettering data is not included, if there is lettering data registered by the subscriber of the sending terminal (100), such lettering data may be included. And even if there is lettering data registered by the subscriber, if the sending terminal (100) is connected to the dedicated network (300), the lettering data mapped to the dedicated network (300) is transmitted first by being included in the call connection request, so that the lettering data mapped to the dedicated network (300) is displayed on the receiving terminal (200).
[0060] Additionally, the caller information display service provider (603) can determine whether to include mapped lettering data in the call connection request based on whether the identified identifier is a dedicated network and whether the time at which the call connection request was sent satisfies the time information mapped to the identified identifier. That is, even if the sending terminal (100) is connected to the dedicated network (300), if the current sending time has passed working hours, the lettering data mapped to the dedicated network (300) is not displayed. In this way, even if the subscriber of the sending terminal (100) does not use multiple phone numbers, the company information of the workplace is provided to the recipient as sending information during working hours at the workplace, and selective operation is possible so that the company information is not displayed even if it is at the workplace but after working hours have passed.
[0061] Now, a series of processes for providing a caller information display service based on the aforementioned configuration will be described by example.
[0062] At this time, the same reference numerals are used in conjunction with the configurations of Fig. 1 and Fig. 2.
[0063] FIG. 3 is a flowchart illustrating a method for providing a caller information display service according to one embodiment of the present invention.
[0064] Referring to FIG. 3, the caller information display service provider (603) of the core network (600) maps and registers lettering data for each identifier of one or more dedicated networks (300) (S101). The lettering data may include business lettering data registered by corporate subscribers established in the dedicated network (300).
[0065] The sending terminal (100) transmits a call connection request through the wireless access network (300 or 400) it is connected to (S103).
[0066] The caller information display service provider (603) of the core network (600) checks the identifier of the wireless access network connected to the sending terminal (100) (S105). Here, the identifier may be included in the call connection request or may be checked during the bearer setup process.
[0067] The caller information display service provider (603) of the core network (600) determines whether the wireless access network connected to the sending terminal (100) is a dedicated network based on the confirmed identifier (S107). That is, it can determine whether the confirmed identifier is the identifier registered in step S101.
[0068] If it is a dedicated network, lettering data mapped to the verified identifier is extracted (S109) and included in the call connection request (S111). Then, in step S111, the call connection request containing the lettering data is transmitted to the receiving terminal (200) (S113). Then, the receiving terminal (200) displays a call connection screen containing the lettering data (S115).
[0069] If it is not a dedicated network, the call connection request received in step S103 is transmitted to the receiving terminal (200) (S117). Then, the receiving terminal (200) outputs a call connection screen that does not include the lettering data registered in step S101 (S119).
[0070] Of course, at step S119, the caller ID display screen can also be output. That is, at step S117, a lettering service based on the subscriber profile can also be provided.
[0071] FIG. 4 is a flowchart illustrating a method for providing a caller information display service according to another embodiment of the present invention.
[0072] Referring to FIG. 4, the caller information display service provider (603) of the core network (600) maps and registers each lettering data and each time information for each distinguisher of one or more dedicated networks (300) (S201).
[0073] When a call connection request is received (S203) from a sending terminal (100) of the core network (600), the sending terminal (100) checks the identifier of the wireless access network connected to the sending terminal (100) (S205).
[0074] The caller information display service provider (603) of the core network (600) determines whether the identified identifier is a private network (S207). If it is a private network, it checks the time when the call connection request was sent (S209).
[0075] It is determined whether the confirmed time satisfies the time information mapped in step S201 (S211). If it satisfies it, the mapped lettering data is included in the call connection request and transmitted to the receiving terminal (200) (S213).
[0076] On the other hand, if the dedicated network is not in step S207 or the time information mapped in step S211 is not satisfied, a call connection request that does not include the lettering data registered in step S201 is transmitted to the receiving terminal (200) (S215).
[0077] Meanwhile, the core network (600) is a network system that performs key functions for mobile communication services, such as mobility control and switching between wireless access networks (300, 400, 500), and can be implemented with various functional elements. Taking the LTE (Long Term Evolution) system as an example, the core network (600) may include a Mobile Management Entity (MME), a Serving Gateway (S-GW), a Packet Data Network Gateway (P-GW), and a Call Session Control Function (CSCF).
[0078] Additionally, the core network (600) further includes an application server, which is a core network entity including the lettering database (601) and the caller information display service provider (603) described in FIG. 2.
[0079] At this time, the packet data network gateway (P-GW) can be divided into a private network P-GW and a public network P-GW. The private network P-GW processes call processing through the private network (300), and the public network P-GW processes call processing through the public network (400). At this time, the public network P-GW corresponds to the existing P-GW, and the private network P-GW may be a new configuration added according to an embodiment of the present invention. That is, the MME / S-GW additionally implements a function to identify whether it is a private network through a network identifier, and if it is a private network, transmit the call connection request to the private network P-GW, and if it is a public network, transmit the call connection request to the public network P-GW. The process of providing a caller information display service according to such an embodiment is as follows.
[0080] FIG. 5 is a flowchart illustrating a method for providing a caller information display service according to another embodiment of the present invention.
[0081] Referring to FIG. 5, the application server maps and registers each lettering data for each separator of one or more dedicated networks (300) (S301).
[0082] The sending terminal (100) transmits a call connection request to the wireless access network (300 or 400) it is connected to (S303).
[0083] The wireless access network (300 or 400) connected to the transmitting terminal (100) transmits the call connection request to the MME / S-GW (S305).
[0084] The MME / S-GW checks the identifier of the wireless access network connected to the transmitting terminal (100) to determine whether it is a dedicated network or not (S307).
[0085] If it is determined to be a private network, the call connection request is transmitted to the private network P-GW (S309). Then, the private network P-GW transmits the call connection request to the application server to request lettering data (S311).
[0086] The application server extracts lettering data mapped to the identifier of the wireless access network connected to the originating terminal (S313) and includes it in the call connection request (S315). Then, it transmits the call connection request containing the lettering data to the dedicated network P-GW (S317).
[0087] The private network P-GW forwards the call connection request received from the application server to the CSCF (S319).
[0088] CSCF transmits the received call connection request to the receiving terminal (200) (S321). Then, the receiving terminal (200) outputs a call connection screen containing lettering data (S323).
[0089] On the other hand, if it is not determined to be a private network at step S307, that is, if the wireless access network connected to the sending terminal (100) is a public network, the MME / S-GW transmits the call connection request to the public network P-GW (S325).
[0090] The public network P-GW forwards the call connection request to the CSCF (S327).
[0091] CSCF transmits the received call connection request to the receiving terminal (200) (S329). Then, the receiving terminal (200) outputs a call connection screen that does not include lettering data (S331).
[0092] The configuration of the core network of FIG. 5 described above can be modified in various ways according to embodiments of the present invention, and the corresponding call processing procedure can also be of various forms, so it is not limited to the description above.
[0093] Meanwhile, the caller information display service according to an embodiment of the present invention may be provided in conjunction with a time clock check system. Such an embodiment is as follows.
[0094] FIG. 6 is a flowchart illustrating a method for providing a caller information display service according to another embodiment of the present invention.
[0095] Referring to FIG. 6, when the core network (600) receives a call connection request from the sending terminal (100) (S401), it transmits a request to confirm attendance check to an attendance check system (not shown) (S403).
[0096] The time clock check system (not shown) checks the time clock or time clock check status of the subscriber of the sending terminal (100), and then transmits the time clock check confirmation response to the core network (600) (S405).
[0097] The core network (600) determines whether the subscriber of the sending terminal (100) has come to work or left work based on the clock-in / clock-out check confirmation response (S407).
[0098] At this time, if it is determined that the caller has gone to work, lettering data mapped to the identifier of the wireless access network connected to the sending terminal (100) is extracted (S409) and included in a call connection request (S411), and then this call connection request is transmitted to the receiving terminal (200) (S413). Then, the receiving terminal (200) outputs a call connection screen containing the lettering data.
[0099] On the other hand, if it is determined that the caller has not yet gone to work or has left work, the received call connection request is transmitted to the receiving terminal (200) (S415). Then, the receiving terminal (200) displays a call connection screen that does not include lettering data. Of course, the lettering data that is not included refers to lettering data mapped to a identifier of the wireless access network, and if there is lettering data registered in the profile of the subscriber of the sending terminal (100), such lettering data may be included in the call connection request.
[0100] As such, when making a call upon arriving at work, the company's lettering data is displayed on the receiving terminal, but when making a call upon leaving work, the company's lettering data is not displayed on the receiving terminal.
[0101] The embodiments of the present invention described above are not implemented only through devices and methods, but may also be implemented through a program that realizes a function corresponding to the configuration of the embodiments of the present invention or a recording medium on which such program is recorded.
[0102] Although embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims also fall within the scope of the present invention.
