Description

Local Paging Cellular System {LOCAL PAGING CELLULAR SYSTEM}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paging method of a cellular network based mobile communication system, such as a mobile phone, and to a local paging cellular system.

Particularly, in the present invention, a part of the existing system paging is handled by the local paging base station, and the paging information transmitted from the local paging base station controls the operation mode of the subscriber station or additional information appropriate to the region or place where the subscriber terminal is located. The present invention relates to a local paging cellular system that can be received and used by a subscriber (terminal) using local paging.

1 is a block diagram schematically illustrating a conventional cellular system configuration, and includes a pilot channel, a paging channel, and a traffic channel (eg, through a forward link 103 from a base station 101 to a terminal 102). information is provided through a traffic channel, and information is transmitted from the terminal 102 to the base station 101 through the reverse link 104.

The paging channel is a channel common to all terminals and includes information about the system and paging information about a specific terminal.

The terminal 102 is a mobile communication terminal that provides voice calls and other additional services to a user (subscriber) through a cellular system. The terminal 102 monitors a paging channel at a slot cycle index to update information about the system. ), And receive the paging information delivered to it.

The communication between the base station 101 and the terminal 102 is performed by a time division multiplexing technique in units of time slots.

This is shown in FIG.

Paging of the system, that is, the base station 101 is performed based on time slots. In FIG. 2, a space divided by a small rectangle represents one time slot.

With respect to paging of the system, terminals decode slots determined for each terminal and receive information delivered to them.

In Fig. 2, the paging decode of the terminal 1 is represented by a hatched rectangle, and the paging decode of the terminal 2 is also represented in correspondence with the paging of the system.

Each terminal receives the information about the paging and the base station that the phone has been called by decoding its slot, and performs the appropriate operation corresponding to this information.

As shown in Figs. 1 and 2, paging in a conventional cellular system is based on time slots, and each terminal decodes a slot defined by the respective terminal in response to paging transmitted through a forward link from the base station. Communication between the terminals is made.

Thus, in a sense, conventional cellular system paging is a global concept. In other words, it is difficult to have specialized information or additional services for a specific region. For example, when a subscriber accesses a specific place in a certain area, depending on the characteristics of the place or the environment, restrictions on the function of the terminal (especially the phone mode such as ringing and vibration) may be required and the area. Although a service of information having a special meaning may be required only for a location or a place, such a requirement is difficult to be met in a conventional global paging concept.

As an example, suppose a subscriber has access to a public place, such as a venue.

In this case, one of the actions that the subscriber should take may be to change the terminal to vibration mode or turn off the power.

However, conventionally, in this case, unless the subscriber directly manipulates the terminal to change to the vibration mode, there is a possibility that the incoming call will sound, and in fact, we often encounter this case, and the incoming call of the terminal during the performance in the venue You see the ringing here and there. Of course, if the subscriber changes the terminal to the vibrate mode or the power is turned off in case of such a case, the above difficulty does not have to be intact, but it is thought to turn off the power to the vibration mode or to switch to the vibration mode. Not as easy as

As another example, suppose a subscriber passes by a department store in a particular area.

By the way, let's say that the department store has a sale period as a special event.

In such a case, it is difficult for subscribers to obtain information on the sale event of the department store except for directly contacting the department store advertisement.

In other words, access to specialized information in a particular region (in this case, department store sales information) is virtually blocked, and from a mobile subscriber's point of view, there may be hope for such specialized information services, but the conventional global concept of cellular In paging, this specialized information service is difficult.

The present invention performs local paging for a specific information service for a specific area (place) together with system paging of a base station, thereby controlling the appropriate terminal operation required in the area (place) when the subscriber accesses a specific area (place). It also provides a local paging cellular system to receive the necessary information.

The present invention is a cellular system having a base station that performs system paging and a local paging base station that performs limited paging for a particular region (place), which does not transmit power (ie, does not paging) in the system paging of the base station. System paging is performed through a dummy paging slot, and at this dummy paging slot time, the local paging base station performs local paging containing information appropriate for the region (place), and the terminal transmits the local paging information. The present invention provides a local paging cellular system that receives and decodes an automatic control of proper terminal operation or a service of specialized additional information according to a location (place) where a subscriber is located.

3 is a diagram schematically illustrating a relationship between a local paging system and a cellular system of the present invention.

A local paging base station 302b is arranged around the base station that performs limited paging for a specific area (place) 302a within a certain area that the base station 301 has jurisdiction over.

The place where the local paging base station 302b is installed may be, for example, a public building such as a theater or a performance hall, a store such as a department store, or a subway station.

System paging by the base station 301 is to make a voice call through the communication with the subscriber, and other additional services as before.

Local paging by the local paging base station 302a performs the information service required when the subscriber is located in a particular place.

The base station 301 periodically performs paging through an empty slot that does not transmit power, that is, a dummy paging slot when performing system paging, and the local paging base station 302a performs local paging at the empty slot timing. .

4 shows the relationship between system paging and local paging.

The slots represented by dots in the paging of the system are empty slots (dummy paging slots) that do not transmit power.

Local paging is shown at the empty slot timing, which is represented by black filled slots.

Each terminal receives the information about the paging and the base station that the phone has been called by decoding its system paging slot, and performs the appropriate operation corresponding to this information.

In addition, the terminal having the function of receiving local paging information receives and decodes the local paging information, thereby receiving a specialized service according to the location (place) where the subscriber is located.

5 is a block diagram illustrating a base station, a local paging base station and a terminal for a local paging cellular system of the present invention.

The system paging base station 501, the local paging base station 502, and the terminal 503 are shown.

The subscriber station 503 includes, in particular, a receiver 504 for receiving local paging information, a decoder 505 for decoding local paging information received by the receiver 504, and a decoder 505 decoded by the decoder 505. A processor 506 for processing local paging information, a switching control unit 507 for phone mode (bell / vibration), and a display unit 508 are included.

As described with reference to FIG. 4, the system paging base station 501 performs system paging through an empty slot that does not page at a predetermined period.

The local paging base station 502 performs local paging as shown in FIG. 4 at the empty slot timing.

Local page information transmitted from the local paging base station 502 is geographic location information (latitude, longitude) of the local paging, and the local paging is a public place such as a theater or a performance hall, the mobile phone (terminal) in the manner mode (vibration mode) It delivers phone mode information to recommend or indicate when it needs to operate, and information that is specific to the building or particular location that is paging locally.

The subscriber station 503 receives local paging information in the middle of the paging information transmitted from the existing base station 501.

The receiving unit 504 of the subscriber station 503 receives the local paging information that is periodically transmitted to the decoder 505 as shown in FIG.

The decoder 505 decodes the received local paging information and supplies it to the processor 506.

The processor 506 performs appropriate processing according to the input local paging information.

For example, if the message recommends switching to the vibration mode in a public place, the message may be output to the display unit 508 on the subscriber station.

Alternatively, if the message instructs the user to switch to the vibration mode in a public place, the processor 506 may control the phone mode switching controller 507 to forcely change the operation mode of the subscriber station to the vibration mode according to the corresponding command.

Alternatively, if the information is specialized in a specific location (building), for example, department store sale information, the corresponding content may be output to the display unit 508 on the terminal.

In addition, the subscriber station 503 may use the location information (latitude and longitude) in the local paging information to determine its exact location in combination with the geographic information system.

The technology of determining the present geographical location of a subscriber (terminal) by linking the geographic information system with the terminal and presenting it to the subscriber can be easily implemented by applying the existing proposal, so detailed description of this is avoided.

As described above, in the present invention, paging is performed periodically through an empty slot that does not transmit power in system paging, and at this timing, the local paging base station performs paging with local information, and the subscriber station performs the paging of the local paging information. Local paging information is processed by decoding the terminal to control the phone mode of the terminal or displaying specialized information.

According to the present invention, in addition to the existing cellular system paging, a subscriber can receive localized paging information specialized according to a region (place) where he is located, and does not affect a terminal that cannot receive and use local information. In addition to maintaining compatibility with the local area, additional localized services are possible.

For example, according to the present invention, in a public place such as a theater or a performance hall, it is recommended to change the phone mode to the vibration mode or to force the control to change to the vibration mode. In addition, when accessing a store such as a department store, if the sale is performed in the store, the corresponding information can be displayed on the subscriber terminal, so that useful information specialized at a specific location can be easily obtained.

In addition, it is possible to provide an additional service that informs the current location of the subscriber by using geographical location information (latitude and longitude) delivered from the local paging base station.
