Description

Additional service method in mobile communication system

The present invention relates to an additional service method for providing a text-based voice mail (VMS) to a user using a short message service (SMS) in a mobile communication system.

In general, a mobile communication system is capable of transmitting a text message to a user's terminal as a single specialized service (SMS) and a wireless data transmission technology are introduced due to the increase in the number of mobile telephone subscribers and the development of a mobile telephone system. Therefore, the development of this technology provides a basis for the user to conveniently access the mobile communication system.

In addition, operators of mobile communication systems have expanded to provide various types of services to meet the needs of mobile subscribers, and in particular, provide various subscribers by creating various services using simple professional service (SMS) capable of simple message transmission. Doing.

Currently, voice mail (VMS) services in mobile communication systems are widely used when subscribers cannot answer or turn off the phone. Therefore, as the number of mobile phone subscribers increases, the use of voicemail of mobile phones is also increasing. As the voicemail of mobile phones is popularized, users demand more convenient functions.

For example, the user needs to provide an interface that can be arbitrarily accessed in a more familiar and familiar form, and considering that a large portion of the mobile phone usage is using a wireless calling supplementary service, a more convenient approach is essential for the user. Required.

However, in the related art, when a user uses a voice mail, the user directly accesses a voice response system (ARS) using a telephone and then accesses a menu by voice guidance, or receives all messages for listening to a stored voice. The voice stored in the mailbox had to be guided. In this case, when the menu of the voicemail box or the depth of the menu is deep, the user had to listen to all the menus, so there were many inconveniences.

For example, in the related art, many wireless calling subscribers use the supplementary services based on voice guidance such as voicemail in order to receive various supplementary services. As the types of supplementary services increase, the composition of the menu becomes complicated. The hierarchy of the menu has deepened. Therefore, in order to listen to the voice guidance desired by the user, it is necessary to listen to the announcement, which is not necessary. Due to the sequential nature of the voice guidance, random access was impossible unless the user remembered the service number. There was a difficult issue.

The present invention has been made to solve the problems described above, by connecting to a voice mailbox or a radio call voice mailbox using a single professional service (SMS) in the mobile communication system to guide the user with voice announcements as well as voice announcements It is an object of the present invention to provide an additional service method for providing a text in a text through an LCD.

The mobile station (MS) 11 is within the range of any base station (BTS) 12, and the information of the terminal 11 passes through the base station 12 and the control station (BSC) 13 controlling it. Information transmitted from the switching center 14 is transmitted to the terminal 11 via the base station 12 and the control station 13.

The mobile station 11 is a terminal (PS) that a user can carry and communicate with while moving. The mobile station 11 uses a forward channel when receiving text and a reverse channel when transmitting. At this time, all text information uses SMS (SMS), and when received, it uses Mobile Terminated (MT) Mobile SMS (SMS), and when sending, MO (Mobile Originated) SMS is used. Use the service.

The mobile communication system uses a data burst message of a paging channel of a CDMA mobile communication system when received, and a data burst message of a forward traffic channel if a user is busy. Send the text message. In addition, a text burst message of an access channel is used to transmit a text message, and a data burst message of a reverse traffic channel is transmitted when a text message is in use.

The text message transmitted and received at the mobile station 11 is connected to the switching station 14 through the base station 12 and the control station 13 for high frequency signal processing and call processing.

A base station (BTS) 12 connects a mobile station (MS) 11 to a control station 13, and includes a digital channel unit (DCU) and a timing / frequency control unit (TCU). , A radio frequency unit (RFU), and a global positioning system (GPS).

In addition, the base station 12 performs a wired / wireless conversion function of communicating with the mobile station 11 over the air and communicating with the control station 103 by wire.

The control station (BSC) 13 connects the base station 12 to the switching center 14 to coordinate the connection between the base stations 12 and serves as a signal processing function for communication between the base station 12 and the switching station 14.

The exchange office 14 has a visitor location register (VLR) 15 and interworks with a home location register (HLR) 16, a voicemail (VMS) 20, and an SCM server 19. Handles mobile subscriber calls.

The exchange station 14 connects with the control station 13 to perform call setup and release functions of the mobile station 11 and to perform various functions related to call processing and additional services.

The visitor location register (VLR) 15 is a database that temporarily stores subscriber information associated with the mobile station 11 while the mobile station 11 is in an area controlled by the visitor location register 15. The information of the mobile station 11 and the subscriber whose location has been registered is retrieved from the home location register 16, is temporarily stored, and mounted in the switching station 14.

The home location register (HLR) 16 is a database that manages various information of mobile subscribers by being connected to an exchange office 14 and a single-specialty center 17. The home location register (HLR) 16 functions to register subscriber locations in conjunction with various exchange stations 14. And stores permanent information and location information of the mobile station 11 and subscribers, and interacts with the visitor location register 15 to support various functions related to call processing and additional services.

Single Expert Center (SMC) 17 is connected to an exchange office 14, a home location register 16, and a single expert service server 18 to play a key role in SMS processing, set SMS parameters, and input signals. It interprets the teleservice identifier (TI) and destination address (Destination Address) and sends it to the corresponding network element. In particular, the single-specialty center 17 transmits a signal input from the switching center 14 to the single-specialty service server 18 when the message is set to the single-specialty service server 18.

The single professional service server 18 is interlocked with the single professional center 17 and connected to an external information provider (IP) and voicemail server 19 through a local area network (LAN). After storing the terminal type, service type, etc. of the professional service subscriber, if the voice mail message is transmitted using the corresponding service identifier, it is transmitted to the voice mail server 19.

The voicemail server (VMS) 19 is in charge of VMS call processing in conjunction with the voicemail box 20, and reads and outputs a message corresponding to the service identifier from the voicemail box (20). In particular, the voicemail server 19 can be easily interworked by forming a signal network of a common line (NO.7) signaling method through a single professional service server 18 and a LAN.

The voicemail box 20 has a physical storage device. The voicemail box 20 is configured to compress and store voice prompts and voices digitally, and analyze the messages of the voicemail server 19 to listen to voice prompts and stored voices.

In the conventional general access method, the mobile station 11 is directly connected to the voice mail server 19 via the switching station 14, but the mobile communication system as described above is connected to the voice mail box 20 through the SMS related system. ) Is connected. Therefore, in order to provide a voice mail message to the user, a separate SMS related network should be used.

In the present invention, the mobile station 11 is connected to the voicemail box 20 through SMS transmission. For this purpose, a separate SMS related parameter should be set in the mobile station 11. These SMS-related international standards are defined in TIA / EIA / IS-637 and some of them are defined separately.

In order to implement the method proposed in the present invention, it is possible to implement a general text message transmission / reception scheme that is currently basically provided as it is. Identifier) can be set separately.

Referring to Table 1, IS-637 communication service identifiers (TIs) are broadly classified into analog mobile phone supplementary services, voicemail notifications, paging and message services.

The present invention can be easily distinguished using one of 4100 to 32512 which is reserved in the communication service identifier (TI) of Table 1.

For example, the present invention can use 4100 as the voicemail text access service identifier separately from the existing text message service 4098.

As described above, a destination address is needed in addition to the above-mentioned communication service identifier (TI). Here, most of the destination address can be easily selected since the preliminary address is set as a preliminary number. In general, the destination address is composed of 10 decimal digits, and serves as a path setting for providing a desired service together with a communication service identifier (TI).

2 is a flowchart illustrating a data processing procedure between a terminal and a voicemail box according to an embodiment of the present invention, and shows a procedure in which a message sent from the mobile station 11 is connected to the voicemail box 20 via an SMS related network.

First, in order to access the short-term service subscriber to the voicemail box 20, the mobile station 11 transmits a short-term service origination message including a communication service identifier (TI) and a destination address for a desired service to the switching center 14. (201).

Subsequently, the exchange 14 analyzes the short-term service origination message received from the mobile station 11 and establishes a route. If it is a general voice call and another short-term service (SMS), the switching center 14 routes to the short-term center 17 (202). ).

Next, the single-specialty center 17 transmits it to the network element to be processed by using the communication service identifier (TI) and the destination address, and if the destination address and communication service identifier (TI) of the corresponding message included in the input signal If is set to the single professional service server 18, and transmits to the single professional service server 18 (203). Here, the routing information should be set in advance in the professional center 17.

Then, the single professional service server 18 recognizes that it is a voicemail server connection message using the corresponding communication service identifier (TI) and transmits it to the voicemail server 19 (204).

Subsequently, when the voicemail server 19 transmits a voicemail connection message including the communication service identifier (TI) and a destination address (205) to the voicemail box 20, the voicemail box 20 receives the received voicemail connection. Analyzes the message and gives voice guidance and stored voice. That is, the voicemail box 20 transmits a response message to the received message as opposed to the reception path to notify the mobile station 11 that the transmission is completed (206 to 210).

As described above, the data processing procedure between the mobile station 11 and the voicemail box 20 may be generated several times by the user until the end of the call.

3 is another exemplary diagram illustrating the interworking of a mobile communication system and a wireless call network to which the present invention is applied. In the drawing, "31" is a paging server and "32" is a text-based voice response system (T-). ARS: Text-assisted ARS), "33" denotes a paging VMS, and "34" denotes a paging system, respectively.

The interworking system to which the present invention is applied comprises a radio call server 31, a text-based voice response system 32, a radio call voicemail box 33, and a radio call system 34 in the CDMA mobile communication system of FIG.
