TECHNICAL FIELD This disclosure relates to grouping of mobile terminal users, and more particularly, to a system and method for forming a group of mobile terminal users based on a communication characteristic between users.

Mobile terminals such as mobile phones, personal digital assistants (PDAs), laptop computers, portable e-mail devices, and the like are widely used in communication. Using these mobile terminals, users communicate with each other via voice or text messages sent over a wireless or wired network. In fact, millions of calls and messages are exchanged around the world every day.

Mobile terminal communication can be broadly classified into personal communication, work communication, and communication related to interests or hobbies. Conventional mobile communication systems typically monitor and collect traffic statistics, such as information about channel events required for the call and any events that occur during the call between the mobile terminal. Such traffic statistics data may represent information related to a particular mobile terminal, including cell dwell time, call duration, call throughput, handoff number, number of outgoing calls from the mobile unit, number of incoming calls to the mobile unit, and the like. Such data may be used to prioritize call processing in mobile communication systems and to assign customized customer service areas, as disclosed in US Pat. No. 5,623,535.

Such traffic statistics data collected by a conventional mobile communication system may represent information related to a call generated by a mobile terminal, but in general communication characteristics between mobile terminal users, such as certain relationships or common interests between users. It does not represent sex. In general, there are certain characteristics or call patterns in communication between mobile terminal users. For example, more frequent phone calls can be made between users with common interests or close relationships. In addition, the contents of the call between users will depend on their hobbies or interests. Despite these call characteristics, conventional communication systems generally did not provide a convenient means of forming or managing groups of mobile terminal users based on call characteristics.

In addition, a user can create or join a virtual club on the Internet for those who have similar interests or want to share and discuss their thoughts about a particular issue or topic. For example, as blogs and Internet cafes become popular on the Internet, they often affect public opinion and the media. In general, however, these clubs required manual input by the user to create or join a club.

The present disclosure is directed to a system and method for forming and managing groups of mobile terminal users that share a common interest or relationship. Call characteristics such as statistics and / or call content of mobile communication between mobile terminal users are examined to predict relationships or interests between users. Based on call characteristics, the systems and methods herein automatically form and manage groups of mobile terminal users to facilitate communication between members.

In the following description, numerous specific details are set forth. However, it will be apparent that embodiments may be practiced without some or all of these specific details. In other instances, well known steps or elements of known methods have not been described in detail in order not to unnecessarily obscure the present specification.

This disclosure provides a system for forming and updating a group of mobile terminal users based on characteristics of calls (eg, communications) exchanged between mobile terminal users, such as traffic statistics of mobile communications between users and communication content. And to a method. According to an embodiment, when the mobile terminal communicates with another mobile terminal, the group management server receives the call content and analyzes the call content data to determine call characteristics indicating a relationship or region of interest. According to another embodiment, the system monitors mobile terminal calls to generate call statistics (eg, call metrics), which are analyzed to predict the level of relationship between users. Based on the analysis, the system automatically forms and / or updates a group of users, and then facilitates communication between users who are notified of the group formed by the user and who choose to be a member of that group.

1 provides a schematic diagram of an embodiment of a mobile communication system 100 for forming and managing mobile terminal user groups based on call characteristics of mobile communication. Mobile communication system 100 controls mobile terminals 112 and 114, a plurality of base stations (BS) 122, 124, and 126, which provide wireless communication links between mobile terminals, and base stations 122, 124, and 126, respectively. A plurality of base station controllers (BSCs) 132, 134, and 136, and a mobile switching center (MSC) 140 for switching call connections. In addition, the mobile communication system 100 includes a group management server 160, which is connected to the MSC 140 via the network 150, and moves mobile traffic such as traffic statistics and call content of mobile calls between mobile terminal users. A group of mobile terminal users is formed and updated based on the characteristics of the calls exchanged between the terminals.

In mobile communication system 100, network 150 may be a wireless or wired Internet, a university or enterprise intranet, a wide area network (WAN), a local area network (LAN), or any other type of network. In addition, the present disclosure includes any, including wireless data networks using CDMA, TDMA, GSM technology, datagram-based networks (eg, the Internet), connection-based networks, virtual circuit-based networks such as asynchronous transmission (ATM) networks, and the like. It can be applied to a network using a variety of communication technologies. In addition, although group management server 160 is connected to MSC 140 via network 150, it can be included in any other device connected to network 150, including mobile terminals, BSs, BSCs, and MSCs. .

According to this embodiment, the MSC 140 monitors and stores traffic statistics for calls made between the mobile terminal 112 and the mobile terminal 114 via the BS 122 and the BSC 132. Traffic statistics may include the number and duration of calls made between mobile terminals 112 and 114 and the geographic location (eg, cell location) of mobile terminals 112 and 114. Traffic statistics obtained by the MSC 140 are provided to the group management server 160 via the network 150. Although a mobile terminal such as mobile phones 112 and 114 is used in the mobile communication system 100, the system has a mobile communication function such as a personal digital assistant (PDA), a portable e-mail device, a laptop computer, and the like. It should be appreciated that the same may be applied to any type of mobile terminal device. Also, for convenience of description, only two mobile terminals 112 and 114 are shown in FIG. 1, but any number of mobile terminals (accessing BS 122, 124 and 126) may be used in mobile communication system 100. Of course, it can be used in.

In addition, MSC 140 monitors calls and messages between mobile terminals 112 and 114 to store call content (eg, voice conversations, text messages, etc.), which are provided to group management server 160. For example, voice calls or messages between mobile terminals 112 and 114 are routed through BS 122, BSC 132 and MSC 140. In particular, a voice call or message encoded at mobile terminal 112 (eg, digitally encoded with a PCM signal) is transmitted to MSC 140 via BS 122 and BSC 132. The MSC 140 then decodes the message into call content and stores it, which is sent to the group management server 160. According to one embodiment, since the voice / text message communicated between the mobile terminals 112 and 114 may include privacy related information, the system 100 collects the voice / text message of the mobile terminal user user. Before requesting consent of the mobile terminal user.

2 illustrates a flow diagram illustrating one embodiment of a method implemented by group management server 160 for forming and managing virtual groups of mobile terminal users. Initially at operation 210, group management server 160 requests and obtains mobile terminal user's consent to collect and analyze the content of calls of mobile terminal users to form or subscribe to one or more mobile terminal user groups. This operation may be performed when the user first subscribes to the mobile service or at any time thereafter. After obtaining the user's consent, in operation 220, group management server 160 monitors the call between mobile terminal users and collects traffic statistics data and / or call content. According to an alternative embodiment, group management server 160 receives call statistics and / or call content from MSC 140 configured to monitor the call and transmit its information to group management server 160. .

Then, in operation 230, traffic statistics data and / or call content are analyzed to predict and classify the types of interests and relationships shared by the mobile terminal users. In this operation, group management server 160 receives and analyzes the content of voice and message calls communicated between mobile terminals to estimate the degree of interest or intimacy shared between communication partners. For example, communication partners with close personal relationships often use emotional words to express their thoughts about each other in communication. If the communicating parties have a personal relationship, the term or keyword representing the relationship, such as "home" or "love", will be used more often in the call. On the other hand, if the call content includes terms or keywords related to a task such as "work", "conference", "due date", etc., the communication counterparts may be considered to have a work relationship. In addition, if the communicating parties share the same interests (eg, sports, arts, recreational activities), the message will include words related to sports such as "soccer", "baseball", and the like. These keywords, or any suitable combination of keywords, are provided, for example, in memory to indicate the type of relationship. Based on the keywords or terms used in the call, group management server 160 parses the call content for these keywords or terms to predict personal, business, or hobby relationships between mobile terminal users.

In addition to call content, traffic statistics of calls between communicating parties may indicate the type of their relationship and how close they are to each other. For example, when communicating parties frequently make long phone calls with each other, this may indicate that they share interests or have some relationship with each other. If the mobile terminals of the communicating parties are in the same geographical location (eg the same cell location), they are likely to live or work close to each other. Similarly, when a call is made indicates the type of relationship that is shared between the communicating parties. For example, if communicating parties frequently call each other during the day, they are more likely to have a business relationship. On the other hand, if they call often at night, they are more likely to have a personal relationship.

With continued reference to FIG. 2, in operation 240, the group management server 160 forms a virtual group of mobile terminal users that are predicted to have relationships based on the analysis of traffic statistics data and / or call content. . After the virtual group is formed, group management server 160 may update or manage the user's virtual group (periodically or dynamically) based on the new call or traffic statistics.

FIG. 3 shows a more detailed block diagram according to one embodiment of the group management server 160 shown in FIG. 1. The group management server 160 is configured to receive call characteristic data, including content and traffic statistics data of the mobile terminal user call, from the MSC 140 via the I / O interface 310. Call characteristic data is stored in a call statistics database 320 (eg, memory, hard drive, etc.) accessed by traffic statistics analyzer 330 and message content analyzer 340. Although call statistics database 320 is described as storing call characteristic data received via I / O interface 310 in FIG. 3, call characteristic data is not stored in database 320 and is not stored in I / O interface 310. ) May be sent directly to traffic statistics analyzer 330 and / or message content analyzer 340. In such a case, the call statistics database 320 may be omitted, and a buffer memory for temporarily storing call characteristic data may be installed in the I / O interface 310, the traffic statistics analyzer 330, or the message content analyzer 340. Can be.

The traffic statistics analyzer 330 analyzes the received traffic statistics data to estimate the level of relationship formed between communication counterparts. As described above, communication counterparts who frequently talk for a long time may be expected to have a close relationship. In addition, the time zone during which communication partners make phone calls indicates the type of their relationship. If communicating parties make phone calls frequently and / or long during the day, they may be expected to have a work relationship. On the other hand, if such phone calls are made during the night, they are likely to have a personal relationship.

The message content analyzer 340 analyzes the contents of the call (eg, voice / text message) to classify the types of relationships that are expected to be formed between the communicating parties. The message content analyzer 340 may include a natural language processing unit or a voice recognition unit for recognizing the content of the voice message. In addition, the message content analyzer 340 may include keywords, terms, or phrases of a plurality of templates classified into a plurality of groups (eg, a task, an individual, and a hobby group). For example, template terms used in sports games such as "soccer", "baseball", "basketball" are defined to indicate a hobby group associated with "sports." In this case, the message content analyzer 340 recognizes the content (or term) of the message, compares the recognized content with a template term, and classifies the message into a corresponding hobby group.

Instead of receiving and storing the content of the mobile terminal user call and analyzing the content in the message content analyzer 340, the group management server 160 only receives keywords extracted from the content of the call and analyzes them in the message content analyzer 340. can do. In such a case, the keyword may be extracted from the content of the call in other components such as BS, BSC or MSC of the mobile communication system 100 shown in FIG. It is also possible for these keywords to be extracted from the call's content in real time without storing the call's content for a significant amount of time. Traffic statistics data may also be determined in a similar manner in components such as BS, BSC or MSC and provided to the group management server 160 along with keywords.

The traffic statistics analyzer 330 and the message content analyzer 340 transmit the analysis result to the inactive virtual group manager 350. The inactive virtual group manager 350 forms an inactive virtual group of users based on the analysis result, and the inactive virtual group includes a user who is predicted to have a certain type of relationship. For example, if the analysis of message and traffic statistics exchanged between users indicates that users frequently make long phone calls during the day and the messages include terms related to sports, inactive virtual groups are commonly associated with sports. Represent colleagues in your company that are interested. Users belonging to inactive virtual groups do not know which group they belong to until they become active group members, as described further below. Information about the formed inactive virtual group is stored in the virtual group database 370. The inactive virtual group manager 350 may further analyze information about the inactive virtual group stored in the virtual group database 370, for example, for managing an institution such as a company, a school, or the like.

4 shows a schematic diagram of one embodiment of an inactive virtual group stored in virtual group database 410. The virtual group database 410 includes four data fields: an active flag 402, a category field 404, a sub-category field 406, and a plurality of members. Contains a data structure for a virtual group, having a member field 408. The virtual group database 410 stores a predetermined number of different categories of inactive virtual groups (e.g., task, individual, and hobby groups as shown in FIG. 4), with each category having a predetermined number of different subs. Have categories (eg, marketing, research, soccer and friendship as shown in FIG. 4).

According to this embodiment, it is expected that users 2 and 3 working in the same department of the company, ie the research department, share the same sports-related interests of football. Similarly, user 1 and user 5 working in the marketing department of a company are expected to have a close personal relationship. As such, each mobile terminal user may belong to at least one inactive virtual group formed by the inactive virtual group manager 350.

When the inactive virtual group is formed, the inactive virtual group manager 350 may perform a process of requesting a user of the inactive virtual group to confirm the formation of the active virtual group. For example, inactive virtual group manager 350 sends a message via I / O interface 310 to request that members of the inactive virtual group respond to whether to join the group.

5 shows a schematic diagram of an embodiment of a mobile terminal 500 that receives a membership request message from an inactive virtual group manager 350. After receiving the membership request message requesting the user to select whether to join an inactive virtual group, the mobile terminal 500 displays a list of virtual groups (ie, a category or subcategory and a group member) on the display unit 510. Display. In response, the user selects one or more of the check buttons 512 to 516 and one of the "ACCEPT" and "REJECT" buttons 517 and 518 to select a membership (or join) in one or more virtual groups. You can accept or decline. After the user selects, the mobile terminal 500 transmits the selection response to the inactive virtual group manager 350.

When the inactive virtual group manager 350 receives a membership response from one or more users of the inactive virtual group, it forms an active virtual group based on the response. For example, when responding to the inactive virtual group manager 350 by indicating that one or more users receiving a membership request message will join the group, the inactive virtual group manager 350 may display an active field (in the virtual group database 410). Setting 402 to " ON " converts the inactive virtual group to an active virtual group and informs the user belonging to the active virtual group of group formation. The newly created active virtual group is then managed and updated by the active virtual group manager 360 as additional calls between existing and / or new mobile terminals are monitored and analyzed.

In addition, the active virtual group manager 360 can provide users of the active virtual group with a cyberspace to share their opinions and communicate with each other. In web pages on cyberspace, such as the Internet or wireless data networks, various functions may be provided to support group activities, such as bulletin boards, three-dimensional virtual worlds, chat tools, and the like.

6 illustrates a flow diagram illustrating one embodiment of a method of forming and managing an active virtual group of mobile terminal users. Once the inactive virtual group of users is formed, in operation 610, a virtual group manager (eg, inactive virtual group manager 350 of FIG. 3) requests that the users of the inactive virtual group choose whether to join the group. And to send to the users. For example, as shown in FIG. 5 above, when the mobile terminal 500 receives a membership request message requesting the user to decide whether to join an inactive virtual group, the mobile terminal 500 displays the display unit. A list of virtual groups is displayed at 510. The user can then accept or decline joining one or more virtual groups by selecting one or more of the check buttons 512-516 and one of the "accept" and "deny" buttons 517 and 518. Based on the selection, the mobile terminal 500 sends a response to the message to the virtual group manager.

As described above, the virtual group manager receives a response from the user of the inactive virtual group in operation 620 and forms an active virtual group based on the response in operation 630. At this point, the virtual group becomes an "active virtual group", which means that the members of the virtual group actively participate in the formation of the group and also know which virtual group they belong to.

Although embodiments herein have been described using traffic statistics data and / or voice / text messages to analyze characteristics of mobile terminal users, any type of data representing characteristics of the user, such as photographic images and video files. May be used to implement embodiments. In addition, any other type of groups may be used to implement the embodiments, as well as traffic statistics and template terms used to classify the message into a group type.

In addition, while various functional components have been described in the embodiments herein, the embodiments may be implemented in hardware, software, firmware, middleware, or a combination thereof, and may be used in a system, subsystem, component, or subcomponent thereof. It should be appreciated. When implemented in software, a component of the embodiments is an instruction / code segment for performing a required task.
