According to the present invention configured as described above, a preferred embodiment of a mobile communication system and an operation method using a marine dedicated frequency will be described in detail with reference to the accompanying drawings.

In the following description of the present invention, if it is determined that detailed descriptions of related well-known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to intention or precedent of a user or an operator, and thus, the meaning of each term should be interpreted based on the contents throughout the present specification. will be.

First, the present invention aims to improve PN mixing by converting a marine-specific frequency not used inland into island base stations and offshore service base stations.

Conventionally, the frequency # FA20 (ch779) is used for maritime services (land-to-shore, coast-to-far sea), which is the same as the land service frequency. However, this conventional technology has a problem in that the service state is poor due to poor wireless environment (Ec / Io bad) due to PN mixing.

So, in order to solve this problem, the present invention uses a marine frequency scheme. In other words, by changing the frequency not used inland to the island base station and the offshore service base station to improve the PN mixing.

In addition, by using different frequencies, it is possible to improve Ec / Io by reducing interference between channels.

In addition, the handoff (H / O) method may use soft handoff between island base stations and hard handoff between island land stations.

In addition, a beacon of a signal copy method is used to acquire a terminal initial system.

Referring to the operation of the present invention in more detail as follows.

<Example 1>

3 to 5 show an example of improving the PN mixed area using a book base station.

Thus, the second island base station 20 performs a soft handoff using a dedicated frequency and a signal copy using an existing operating frequency with the first island station 10, which is an adjacent base station, and performs a land beacon base station ( 30) performs a hard handoff.

That is, the marine dedicated frequency processing unit 21 in the second island base station 20 is soft handoff with respect to the maritime exclusive frequency with the marine dedicated frequency processing unit 11 of the first island base station 10 which is the adjacent island base station in the boundary area 1. Next, in the boundary region 2, the frequency processing unit 31 in the terrestrial beacon base station 30 performs a hard handoff on a marine dedicated frequency and an existing operating frequency.

In addition, the beacon 22 in the second island base station 20 performs signal copying with respect to the existing operating frequency with the beacon 12 of the first island base station 10, which is an adjacent island base station, in boundary region 1. It is connected to the marine dedicated frequency processing unit 21 of the base station 20 to transmit the result of the signal copy so that the signal processing is performed.

And the beacon (12, 22) is to apply a signal copy method for the dedicated frequency tuning in the initial operation of the terminal.

In this case, the dedicated ocean frequency may use channels # FA10 to # FA12 which are M-Zones. 3 and 4 show an example of using a 445 channel (ch445) of # FA12 as the resolution-only frequency. The use area of the maritime dedicated frequency may be a base station which is easy to serve in the marine PN mixed area service base station. In addition, since the maritime frequency uses B-Band frequency, 3FA optical repeater, RFMC-A (Radio Frequency Micro Cell Assembly), optical transformer, etc. can be used in some repeater use areas.

In addition, the existing operating frequency uses a channel 779 (ch779) of # FA20.

In addition, the use of signal copy beacons can solve the problem of acquiring the initial terminal system when using a frequency not included in the preferred roaming list (PRL).

That is, the pilot beacon 32 of the signal copy method is installed in the # FA20 (ch779) that receives the basic information to receive the basic information, it is possible to immediately change to the desired #FA. For example, when three #FAs are used as dedicated frequencies, the terminal receives a signal copy beacon signal of # FA20 (ch779) and tunes to one #FA of the three #FAs.

This allows not only frequencies not included in the PRL but also frequencies in the entire band. That is, it is possible to use other frequencies as well as # FA20 (ch779) which is an existing operating frequency and # FA12 (ch445) which are set to a dedicated frequency for the sea.

In the beacon base station 30, the frequency processor 31 performs a hard handoff with the marine dedicated frequency processor 21 in the second island base station 20, and processes an existing operating frequency.

In addition, the beacon 32 in the land beacon base station 30 is connected to the frequency processing unit 31 of the land beacon base station 30, and performs a signal processing by a pilot method to transmit a pilot beacon signal to the frequency processing unit 31. .

5A illustrates an example in which PNs are mixed, and FIG. 5B illustrates an example in which PN mixtures are changed to a good state by using a dedicated frequency.

The island base stations 10 and 20 performing maritime service use a sea-based FA, and the primary channel is processed by the beacons 12 and 22 in a signal copy manner. Inland land beacon base station 30 is also processed in the beacon 32 for the sea-only frequency.

By using the signal copying beacons 12 and 22 in the island base stations 10 and 20, there is no problem in tuning of the terminal even when using a dedicated frequency in addition to the existing operating frequency.

<Example 2>

6 to 8 show an example of using the island base station and the base station in the inland to improve the PN mixed area on the offshore coast and the PN mixed area on the coast.

The second book base station 20 performs a soft handoff using a sea dedicated frequency and a signal copy using an existing operating frequency with the first book base station 10 and the land base station 40 which are adjacent book base stations.

In such a second island base station 20, the maritime dedicated frequency processor 21 performs soft handoff by the maritime dedicated frequency processor 11 and the maritime dedicated frequency of the first island base station 10 which is the adjacent island base station in the boundary region 1. In the boundary region 2, a soft handoff is performed for the marine dedicated frequency processor 41 and the marine dedicated frequency of the terrestrial base station 40.

In addition, in the second island base station 20, the beacon 22 performs signal copy with the beacon 12 of the first island base station 10, which is the adjacent island base station in the boundary region 1, and the land base station 40 in the boundary region 2. Signal copying is performed with the beacon 42 inside. In addition, the result of the signal copy of the beacon 22 is transmitted to the frequency processor 21.

In this case, the dedicated maritime frequency may use channels of # FA10 to # FA12, which are M-Zones. 6 and 7 show an example of using a 445 channel (ch445) of # FA12 as the resolution-only frequency. The use area of the maritime dedicated frequency may be a base station which is easy to serve in the marine PN mixed area service base station.

Since the maritime frequency uses the B-Band frequency, some repeaters may use 3FA optical repeater, RFMC-A (Radio Frequency Micro Cell Assembly), optical transformer.

In addition, the existing operating frequency uses a channel 779 (ch779) of # FA20.

This second embodiment is different in that the land base station 40 also uses a marine dedicated frequency compared to the first embodiment. For this reason, the base station 40 performs hard handoff with the adjacent base station of the land.

The land base station 40 performs soft handoff and signal copy with the second island base station 20 and performs hard handoff with the neighboring base station.

To this end, the maritime dedicated frequency processor 41 in the terrestrial base station 40 performs a soft handoff with the maritime dedicated frequency processor 21 in the second island base station 20 and performs a hard handoff with an adjacent base station.

In addition, the beacon 42 in the terrestrial base station 40 will perform a signal copy with the beacon 22 in the second island base station 20.

On the other hand, Figure 9 is a table showing the frequency status in each area currently being serviced to set the marine dedicated frequency used in the present invention. By using M-Zone # FA10 ~ # FA12 as the dedicated frequency for the sea, it is less affected by the sea. Preferably, # FA12, which is a 445 channel ch445, may be used.

As such, when using a dedicated maritime frequency, it is possible to implement a maritime service without using PN by using an existing base station without changing a subscriber station.

10 is a table showing the details of the beacon pilot and signal copy used in the present invention. In pilot mode, the signal is pilot only, but in signal copy, pilot, paging, sync, and traffic are copied for hopping and continuous. .

11 is a flowchart illustrating a method for operating a mobile communication system using a marine dedicated frequency according to an embodiment of the present invention, which shows an example of improving a PN mixed area at near-shore seas and a PN mixed area at a coast using a island base station. .

Therefore, it initializes terminals used in mobile communication systems such as 1X terminals, 2G (Two Generation) terminals, and EvDo (Evolution Data Only) terminals.

And between the island islands (10, 20) of the maritime signal copy between the soft handoff using the maritime dedicated frequency and the beacons (12, 22) using the existing operating frequency, the maritime island of the base station (20) and land beacons The hard handoff is performed between the base stations 30.

FIG. 12 is a flowchart illustrating a method for operating a mobile communication system using a marine dedicated frequency according to another embodiment of the present invention, wherein a island base station and an inland base station are used to improve a PN mixed area in a near-shore sea and a PN mixed area in a coastal area. It is an example.

After initializing the terminal of the mobile communication system, between the sea island base stations (10, 20) and the land base station (40) between the soft handoff using the marine dedicated frequency and the beacons (12, 22, 42) using the existing operating frequency. After performing the signal copy, the land base station 40 performs a hard handoff with the neighbor base station.

FIG. 13 is a flowchart illustrating an initialization method in a 2G terminal when initializing a terminal in FIGS. 11 and 12.

Therefore, the 2G terminal operates in the order of primary (ch779), secondary (ch738) applied to the Number Assignment Module (NAM) for number assignment. That is, the 2G terminal performs pilot acquisition and synchronization of the base station, and tunes to the primary frequency. It receives the channel list through the paging channel, performs a hash function, and then synchronizes to the corresponding FA. In other words, the tuner first tunes to ch779 and then moves to ch445, a resolution-only frequency.

FIG. 14 is a flowchart illustrating an initialization method in a 1X terminal upon terminal initialization in FIGS. 11 and 12.

In the initial operation, the 1X terminal operates in the PRL list order and then performs the same operation as the 2G terminal.

So, in the case of 1X terminal, the frequency sequence may proceed as follows.

# FA2 (ch29)-> # FA4 (ch111)-> # FA6 (ch193)-> # FA20 (ch779)-> # FA19 (ch738)

In the case of the EvDo terminal, the frequency sequence may proceed as follows.

# FA2 (ch29)-> # FA4 (ch111)-> # FA6 (ch193)-> # FA20 (ch779)-> # FA19 (ch738)-> # FA9 (ch316)-> # FA8 (ch275)-> # FA10 (ch363)

On the other hand, the ping pong phenomenon due to beacon overlapping phenomenon may occur due to the long-distance due to the characteristics of the sea propagation. This can be solved by deriving an appropriate output value through the beacon power adjustment test so that there is no overlap between beacons at sea.

There is also no need to install large numbers of beacons for handoffs along the shoreline. That is, a question may arise whether a beacon should be installed at all of the inland base stations of the nearby coast for handoff between islands and inland. However, this can be solved by installing beacons in only a few of the coastal base stations (approximately 20%) and having one antenna direction towards the coast. Because it is a dedicated frequency that is not used in the surrounding area, it can cover a large area, so there is no need to install beacons in large quantities.

As such, the present invention improves PN mixing by converting a marine-specific frequency not used inland into island base stations and offshore service base stations.

As described above, the mobile communication system and the operation method using the marine dedicated frequency according to the present invention has the effect of improving the PN mixing by transforming the marine dedicated frequency not used inland to the island base station and the offshore service base station have.

By improving the quality of mobile communication system, customer satisfaction using mobile communication service can be realized, and the investment cost can be reduced by improving the defective area without facility investment.

Although the above is limited to the preferred embodiment of the present invention, the present invention is not limited thereto, and various changes, modifications, and equivalents may be used. Therefore, the present invention can be applied by appropriately modifying the above embodiments, it will be obvious that such application also belongs to the scope of the present invention based on the technical idea described in the claims below.
