Description

Method of performing broadcast service of short message in communication system

The present invention relates to a method of performing a broadcast service of a short message in a communication system.

In general, a broadcast message service provided to subscribers in a service of a mobile communication system such as CDMA is delivered to a mobile terminal (or mobile station) owned by the subscriber through a control channel, a paging channel and a traffic channel. Done. This broadcast message does not require an answer to whether the terminal has received the broadcast message.

Here, there are three methods of broadcasting in which a broadcast message is transmitted through the call channel. As a first method, a multi-slot broadcast message transmission (Multi-Slot), which sends a broadcast message to all slots of a control channel so that a broadcast message can be sent through all mobile terminals within a service area covered by an arbitrary base station. Broadcast Transmission) method. This is the simplest and fastest way without any message delay. However, this method places a heavy load on the control channel, making it impossible to process other messages. Second, there is a multi-slot broadcast paging method. This method is an improvement on the multi-slot broadcast transmission method. In this case, a small general page message is transmitted to all slots of the control channel instead of a large broadcast message to inform all terminals of the broadcast and then deliver the broadcast message. As a third method, there is a periodic broadcast paging method. This method informs the terminal that the base station will periodically deliver broadcast messages in the most efficient way. Then, it is a method of delivering a broadcast message at a certain period. The first slot of the period notified to all terminals is referred to as a reference slot, which transmits a general page message including broadcast addresses of messages to be forwarded. The terminals can use this broadcast address information to know what kind of message is coming and when it should receive the message. The broadcast message corresponding to each broadcast address should be transmitted in cycles of three slots after the reference slot. The terminal (or mobile station) receiving the broadcast message through the above methods displays the message on its display device. In addition, the conventional technology is based on IS-637, which is a short message related standard, and uses the standards of IS-95 and J-STD-008 for message transmission between a wireless section, that is, a base station and a terminal.

1 is a block diagram illustrating a network configuration of a general CDMA system for broadcasting a short message. In FIG. 1, the base station BS is considered to include a base tranceiver subsystem and a base station controller. Referring to FIG. 1, a mobile communication service using a CDMA method is basically a public switched telephone network (PSTN) 1 for general subscription telephone service provided by a network operator, and communication between a telephone and a vision system. The integrated service digital network (ISDN) 2, which digitalizes a service by one subscription line and transmits and exchanges, provides a wired or wireless call to a mobile subscriber.

The mobile switching center (MSC) 3a performs a circuit switching and relay call processing between subscribers so that the mobile subscriber can make a call with another mobile subscriber or a general wired network subscriber using a mobile communication service. In order to provide a higher quality communication service, hand-off, roaming, and other functions are performed. In addition, a transport layer (hereinafter referred to as a transport layer) in broadcasting message transmission is illustrated in FIG. 3 to 20).

In addition, the base station 3b is connected to a mobile station 4 that is moving or stationary at a specific position through a radio frequency connection for a call, and the mobile station 4 is wired with an apparatus for controlling the base station 3b. It connects wirelessly and takes charge of a relay layer (hereinafter referred to as a relay layer) (30 to FIGS. 2 and 3) in transmitting a broadcast message.

In addition, it is a place containing information related to various mobile communication connected to the mobile communication switching center 3a, the current position information of the mobile station 4, the status of the mobile communication subscriber, statistical data related to mobile communication and various service related information. It contains a back. Also, a home location register 6 for interconnection with wired and wireless communication subscribers, and a visitor location register used in connection with a mobile communication switching center 3 for retrieving information for processing calls from visiting subscribers of other communication networks ( VLR: Visitor Location Register (7).

The Cell Broadcast Center 7 which plays an important part in the broadcast message transmission is responsible for the transport service layer (hereinafter referred to as Teleservice Layer) (10 in Figs. 2 and 3), and a short message providing center (Short). Message Entity 8 provides a broadcast message to the message center 7.

In the network of the basic CDMA system of FIG. 1 configured as described above, a mobile communication service process will be omitted, and only a service for performing a service of a broadcast message according to the present invention will be described.

Referring to FIG. 1, a communication service network operator first selects one of three broadcast message transmission methods through a call channel described above.

The short message providing center 8 sends the broadcast message to be sent to the message center 7 in charge of the Teleservice Layer 10, and the message center 7 sends the mobile communication switching center 3a in charge of the Transport Layer 20. Through the base station 3b in charge of the relay layer 30 of FIGS. 2 and 3, the broadcast message is finally delivered to the mobile station 4.

Here, the base station 3b loads the contents of the broadcast message into a data group message (hereinafter referred to as a data burst message) and transmits the contents of the broadcast message to the mobile station 4 through the call channel through the selected broadcast message transmission method.

The above method of using Data Burst Message is Multi-Slot Broadcast Transmission, and the remaining Multi-Slot Broadcast Paging and Periodic Broadcast Paging are used for general calling. Messages (hereinafter referred to as General Paging Messages) and data burst messages.

In addition, the address portion of the data burst message or general paging message is filled with a broadcast address for transmitting a broadcast message, not a unique address of the mobile station 4. The mobile station determines whether to receive a broadcast message according to the broadcast address. do.

FIG. 2 shows a broadcast address for transmitting a broadcast message according to the prior art, wherein a 2-bit priority bit, a 6-bit message identification bit (MESSAGE_ID), an 8-bit zone identification bit (ZONE_ID), It consists of 16 bits of service bits (SERVICE) and 8 bits of language bits (LANGUAGE).

In more detail about the broadcast address configured as described above, the two-bit priority bit sets the priority of the broadcast messages to distinguish the broadcast messages to be prioritized when a plurality of broadcast messages are transmitted. .

The above 6 bit message identification bit (MESSAGE_ID) is a bit that distinguishes a duplicate message to avoid retransmitting a message that has already been transmitted, and the 8 bit zone identification bit (ZONE_ID) is the same broadcast message received from another zone. Bit to distinguish.

In addition, a 16-bit service bit (SERVICE) is a bit for classifying a broadcast message transmission service by an item, and an 8-bit language bit (LANGUAGE) is a language indicator bit for classifying a language used for a broadcast message.

3 is a diagram illustrating a protocol stack configuration for a broadcast message transmission service.

Looking at the protocol stack configuration from the lower layer, the link layer 40 is a protocol layer for establishing a connection on a communication line for a communication service.

The relay layer 30 is a protocol layer which is in charge of the base station 3b of FIG. 1 and discards the duplicated received message if the broadcast message having the same broadcast address is received within the broadcast message reception period. It is responsible for routing, addressing, call setup, and termination.

The transport layer 20 is a protocol layer that is in charge of the mobile communication switching center 3a and transmits broadcast messages between the message center 8 and the base station 3b. In addition, the transport layer 20 is responsible for call connection management, data separation, and data flow control. do.

The teleservice layer 10 is a protocol layer that is in charge of the message center 7 and provides a broadcast message transmission service through broadcast message sub-parameters.

In this case, when the broadcast message provided through the broadcast message sub-parameter of the teleservice layer 10 is to be transmitted, a transport layer 20, a relay layer 30, and a link layer, which are lower layers of the teleservice layer 10, are transmitted. It transmits through the parameters provided by 40.

The sub-parameters for the broadcast message of the Teleservice Layer 10 mentioned above are shown in FIG. All of the above sub-parameters can be used optionally. In general, the subparameters of this broadcast message are message identifier, user data, message center time stamp, validity period-absolute, and relative availability period. -relative, priority indicator, alert on message delivery, and language indicator.

FIG. 5 is a diagram illustrating a primitive form of the relay layer 30 and the transport layer 20 in the configuration of the protocol stack of FIG. 2.

Primitive between the two layers has four stages: a request step for requesting to perform an arbitrary task, an indication step for notifying the requested task, and a response for responding to the informed task ( Response), and a confirmation step of confirming a response to the request.

The relationship between the relay layer 30 and the transport layer 20 by the above primitives is as follows.

After requesting a broadcast message transmission request from the transport layer 20, the relay layer 30 sends an indication indicating a broadcast message transmission to the transport layer 20, and at this time, the transport layer 20 ) Responds to whether to allow or reject the broadcast message transmission.

In response to the above response, the transport layer 20 performs transmission of the broadcast message through confirmation of the relay layer 30. As described above, according to the related art, contents corresponding to the received broadcast message (eg, a telephone number) are simply displayed on the display device of the terminal. Then, when the subscriber who has received the broadcast message is interested in the information of the received broadcast message, the displayed number is first memorized to confirm the information. Pressing the memorized number again connects with the provider of the broadcast message and confirms the information.

As described above, according to the related art, there was no function except displaying the received broadcast message on the display device of the terminal such as a liquid crystal display. Therefore, the following problems exist.

First, if a user wants to store a contact in the address book of a terminal for later use of a contact regarding a received broadcast message, the displayed contact must be memorized. The user then has to store the memorized contact in the address book another procedure on the terminal.

Second, when the user wants to check the information of the received broadcast message, the user must memorize the displayed telephone number. Then, you must press the memorized phone number on the keypad to connect with the information provider of the broadcast message. Thus, there is a need to memorize the number and dial again.

Third, the above two inconveniences reduce the quality or efficiency of the broadcast service of the originally intended short message.

An object of the present invention is to provide a method for performing a service of a broadcast message in a communication system that enables a user of a terminal to easily and conveniently talk to an information provider such as a service provider that provides a desired broadcast message.

It is another object of the present invention to provide a method of performing a broadcast message service in a communication system that allows a terminal user to easily store a telephone number and / or name of an information provider providing a broadcast message desired by a terminal user in an address book of the terminal for future use. It is to provide.

In order to achieve the above object, the present invention additionally uses two broadcast parameters subparameters. One sub-parameter (third party call name) is for inserting the name of the information provider and the other sub-parameter (third party call number) is for inserting the information provider's telephone number.

In order to achieve the above object, the message center includes in its broadcast message the name and telephone number of the information provider requesting the transmission of the broadcast message using its third party call name (third party call number). When the terminal receives the broadcast message, it checks whether there are such sub-parameters in the broadcast message. So, if there are those subparameters, the terminal performs the procedures to achieve the above objectives.

According to the present invention, when the message center receives from the information provider a request message for delivery of a broadcast message including the name and telephone number of the information provider, two message parameters (third party call name, third party call) for the broadcast message are received. insert each into number).

The broadcast message with two parameters inserted by the message center with the name and telephone number of the information provider is sent to all terminals via the base station.

When the terminal receives a broadcast message having subparameters in which the information provider's name and telephone number are inserted, the terminal displays the contents, the telephone number and the name of the subparameters for the broadcast message in a predetermined order on the display device therein.

When desired by the terminal user, the terminal performs the procedure for setting up a call channel so that the information provider and the terminal user can directly talk with the telephone number of the received information provider.

Therefore, when the service provider transmits advertisements and public information using the broadcast service of the short message, the terminal user can easily talk to the information provider of the desired broadcast message. In addition, the telephone number and / or business name of the information provider can be easily stored in the address book of the terminal for future use.

Hereinafter, a method of performing a broadcast message service in a mobile communication system according to the present invention will be described with reference to the accompanying drawings.

In the description of the present invention, the drawings used in the foregoing description of the prior art may also be used as it is.

6A to 6B are tables showing subparameters of a broadcast message according to the present invention. The table of FIG. 6A has the same subparameters as the conventional broadcast message shown in FIG. 4 except for two subparameters (third party call number, third party call name). In the present invention, new two subparameters (third party call number, third party call name) are added to the broadcast service format of a short message used to transmit a broadcast message in the teleservice layer 10 of FIG. As described above, the broadcast message is transmitted from the base station 3 of FIG. 1 to the mobile station 4. Prior to this, in order to implement the present invention, an information provider, such as a service provider, needs to provide information, its name and / or contact information (for example, a telephone number) to the message center 7 of FIG. Send to). The message center 7 inserts the information provider's name (e.g. business name) and telephone number into the broadcast message of the information provider using the two subparameters added above (third party call number, third party call name). do.

The table of FIG. 6B shows the same subparameters as the conventional broadcast message shown in FIG. 4 except for one third parameter (third party call number). In the description of one embodiment of the present invention will be described with reference to Figure 6a.

Hereinafter, a broadcast message processing procedure in the message center 7 for implementing the present invention will be described with reference to FIG. First, the message center 7 receives a request for delivery of a broadcast message from an information provider such as a service provider. The information provider then provides his or her telephone number (or contact) and / or name (or business name) with the information. Subsequently, the message center 7 checks whether the information provider requires the transmission of not only the information for the broadcast message but also its contact and / or business name in the broadcast message. If the information provider wishes to deliver the contact and / or business name forwarding, the message center 7 assigns the contact and / or business name to the third and third party call names, respectively. Insert it. Then, the message center 7 transmits to the base station 3 of FIG. 1 a message for requesting delivery of a broadcast message including the above two sub-parameters (third party call number, third party call name). On the other hand, the base station 3 transmits the delivery request message of the received broadcast message toward the mobile station 4. In other words, when the message center 7 receives bearer information for a short broadcast message including a contact and / or business name from an information provider, the third party call number may be additionally added when configuring the broadcast message of the teleservice layer. The information provider's contact information is inserted into the third party call number in the above third party call number, and then the request message of the broadcast message is transmitted to the base station 3 of FIG.

On the other hand, the base station 3 transmits the broadcast message requested to be transmitted from the broadcast message center 7 to all the terminals 4 through the control channel (paging channel) and the call channel.

In the following, a process of receiving a broadcast message from the base station 3 at the subscriber station (or mobile station) 4 side will be described with reference to FIG. First, the terminal 4 checks whether a sub-parameter (third party call number) and a sub-parameter (third party call name) or one of them exists in the received broadcast message. These subparameters or one subparameter may be optionally added at the supplier side. If the parameters do not exist, the terminal 4 performs the general procedure of processing the received broadcast message. For example, if all of the third party call names and third party call numbers are present in the broadcast message, then the terminal 4 may determine the content of the broadcast message, the telephone number of the information provider and / or the name of the information provider. Are displayed on the display device of the terminal in any order. Four orders can be considered to perform the display. As a first example, the terminal 4 first displays the contents of the received broadcast message on its display device (or display window) (e.g. liquid crystal display) and then for a certain time (e.g. 1-2 seconds). After the elapsed time, the phone number and name (personal or business name) of the information provider included in the third party call number (third party call name) are alternately displayed. As a second example, the content of the broadcast message, the name and / or number of the information provider may all be displayed together on the display device at the same time. As a third example, the content of the broadcast message may first be displayed on the display device, followed by the telephone number and name of the information provider together on the display device. Fourth, the name of the information provider is first displayed on the display device, and then the content of the broadcast message is displayed on the display device. The terminal 4 then checks if the user, ie the service subscriber, has pressed the call key on the key pad. This call key can be assigned any key by the terminal provider. This call key is intended to be used when a service subscriber on this terminal side has a phone number of the information provider providing the broadcast message and wants to talk to the information provider. Thus, when the call key is pressed by the service subscriber, the telephone number of the information provider is inserted into the called parameter of the origination message. This outgoing message is transmitted from this terminal (or mobile station) 4 to the base station 3 of FIG. 1 and by this base station 3 a communication channel between the service subscriber of this terminal 4 side and its information provider. Is set. Since the process of setting the call channel is performed by a general procedure according to the standard regardless of the present invention, a description thereof will be omitted.

On the other hand, if the service subscriber does not press the above key after the telephone number and name are displayed, the terminal 4 checks whether the subscriber has pressed the storage key on the key pad. This storage key can also be specified at the time of manufacture by the supplier of the terminal. This storage key may be used by the service subscriber for the telephone number and / or trade name of the information provider included in the third party call name (third party call number) of the broadcast message for future communication with the information provider. It is used for storing in the address book of the terminal 4. The name (or business name) is then stored in the name field of the address book, and the telephone number is stored in the "number field" of the address book. Therefore, as shown in Fig. 8, when the service subscriber presses the storage key, the telephone number and / or name of the information provider is stored in the address book of the terminal 4. Optionally, only the telephone number of the information provider can be stored in the address book or both the telephone number and the name. Therefore, according to the present invention, the following effects can be obtained.

Meanwhile, there may be no third party call name for inserting the name of the information provider in the broadcast message received at the terminal. In this case, when the information provider of the broadcast message does not inadvertently provide its name when sending a request message for delivering the broadcast message to the message center, or the information provider intentionally fails to provide its name. It can be predicted as In this case, the terminal user wants to save not only the phone number of the information provider but also the name, and can press the above storage key. In this case, the third party call name does not exist in the received broadcast message. At this time, if the terminal 4 determines that the third party call name does not exist in the process of checking whether the third party call name exists in the received broadcast message, the subparameter shown in FIG. Among the sub-parameters (user data) including the contents of the broadcast message, the first 10 bytes are extracted and the extracted 10 bytes of data are stored in the "name field" of the terminal address book. Therefore, in this case, the phone numbers can be stored separately regardless of the presence or absence of a third party call name. And later, the terminal user can easily find the desired phone number from the other phone numbers by using the address book.

First, the service subscriber of the terminal 4 side can easily make a call by simply pressing the call key when he wants to contact the provider of the broadcast message.

Second, by simply pressing the save key, the phone number and name of the information provider can be stored in the address book of the terminal for later use.

As described above, the present invention is-, therefore-has an effect.

In addition, the present invention can be applied to the fields, such as --- can see the effect.
