Description

Apparatus and Method for Performing various Protocol-Service in a Base Station}

The present invention relates to a method for simultaneously serving IS-2000 service and 1X EV-DO service to one base station in a mobile communication system, and in particular, replacing only a channel card in a base station installed for an existing IS-2000 service and replacing 1X EV-DO. It relates to a method and apparatus for performing various protocol services in one base station capable of serving.

The rapid technological development of mobile telecommunications is now opening an era in which anyone can receive data at the speed of wired Internet via mobile phones if desired. In other words, the era of using next-generation wireless multimedia services such as high-speed video and multimedia transmission using a mobile phone is coming.

With the announcement of the International Telecommunication Union (ITU), Korea is officially recognized as the world's first and largest third-generation mobile telecommunications country.

CDMA 1X EV (Evolution) -DO (Data Only) is a dedicated protocol for packet data transmission that is completely different from the existing IS-2000 wireless protocol. Its maximum transmission speed is 2.4Mbps when forward direction is available. . This requires a base station device separate from the IS-2000 base station device, but the rest of the system and network components are commonly used.

The 1X EV has largely 1X EV-DO (Data only) and 1x EV-DV (Data and Voice). 1X EV-DO is a packet data-only protocol, which means the existing 1X EV. The 1X EV-DV, on the other hand, is currently undergoing specification and can simultaneously use high-speed packet data and voice.

1X EV has a structure in which forward and reverse channel rates are different because the service received from the system is predominant due to the nature of packet data. If the space diversity is not used in the terminal, it has an asymmetric data rate structure capable of up to 2.4 Mbps in the forward direction and 153.6 Kbps in the reverse direction.

In the case of IS-2000, since the high-speed packet data is implemented in voice-oriented protocols in principle, the maximum transmission speed is limited. In IS-2000 release 0, packet data can be transmitted up to 153.6 Kbps in the wireless section.However, operators can allocate up to 64 Kbps in the case of VOD (Video On Demand) due to capacity problems in the wireless section. to be. Basically, however, 1x EV for packet data service can sufficiently solve the capacity problem of wireless section.

1x EV is an optimized protocol for high-speed packet transmission only. It uses a CDMA channel (1.25MHz), which is the same frequency band as current cdmaOne or cdma2000 systems. In particular, 1x EV maximizes the usage efficiency of wireless section and system by dynamically allocating transmission rate of each subscriber in wireless section and making full use of unique characteristics of packet data. When using a high-speed data transmission technology of 1x EV, Mbps data transmission as defined in IMT-2000 can be achieved. Therefore, various services such as real-time video service, color content, and network game through a terminal such as a video phone can be enabled.

The 1x EV subscriber can use the cdma2000 and 1X EV dual mode terminals to receive the conventional cdma2000 voice service and switch to the 1x EV-DO mode to use the high-speed wireless data service when necessary.

The 1x EV can be serviced by simply building a new base station equipment while using the CDMA2000 system. On the system side, the wireless IP structure is directly connected from the base station to the packet network. Thus, the packet data service can be maximized because the mobile switching center (MSC) has a strong characteristic of a circuit switched network. Since the base station processes the wireless protocol different from the IS-2000, a base station device separate from the existing base station device is required.

At the base station, the BTS and BSC for the 1x EV must be added separately because the physical layer of the 1x EV is fundamentally different from that of the IS-2000. A terminal connected with a 1x EV is directly connected to a Packet Data Serving Node (PDSN) that processes radio data at a base station and receives related services.

Basically, the base station is composed of RF device, digital device, master processor and GPS. However, the wireless protocol of the IS-2000 base station and the wireless protocol of the 1X EV-DO base station are different, so a separate base station device must be used. This means using digital devices differently.

Hereinafter, a conventional base station apparatus will be described with reference to the drawings.

1 is a block diagram schematically showing the configuration of a conventional mobile communication system.

Referring to FIG. 1, the base station includes a base station 110a supporting IS-2000 service and a base station 110b supporting 1X EV-DO.

Therefore, if the service requested by the user 100 is an IS-2000 service, the service is transmitted to the base station 110a supporting the IS-2000 service, and the service requested by the user 100 is a 1X EV-DO service. In this case, the service is transmitted to the base station 110b supporting the 1X EV-DO service.

The IS-2000 base station supports IS-2000 service, and the 1X EV-DO base station supports 1X EV-DO service.

However, since the physical layers of IS-2000 and 1X EV-DO are fundamentally different in the related art, it is a principle that BTS and BSC exist separately for 1X EV-DO, but in this case, expensive equipments are used twice. .

In addition, if two services of the IS-2000 and 1X EV-DO are to be supported to the same base station, the RF device can be shared, but there is a problem of separately operating a channel card, which is a broadband digital signal processing device.

Accordingly, an object of the present invention is to provide a method and apparatus for performing various protocol services in one base station capable of simultaneously performing IS-2000 service and 1X EV-DO service with one base station.

Another object of the present invention is to provide a method and apparatus for performing various protocol services in one base station capable of performing 1X EV-DO service by replacing only a channel card with a base station installed for an existing IS-2000 service.

Referring to FIG. 3, one base station supports IS-2000 service and 1X EV-DO service. Therefore, when the data transmitted from the terminal 300 is received, the base station 310 determines the service usage of the received data and supports the service of the channel card corresponding to the determined service usage.

When the base station 310 performs the 1x EV-DO service with the IS-2000 service by the shelf or in the shelf, the base station 310 needs to know which service to support for each FA.

Second, when the FA is added while the base station 310 is in operation, it is possible by receiving a service usage of the extended FA from the operator with respect to the newly added FA.

That is, the BSM 320 receives the service usage of the extended FA from the operator at the time of FA expansion and transmits it to the base station 310. The base station 310 stores the service usage of the transmitted extended FA in an internal DB. Then, the base station 310 can know the service usage of the FA by using the service usage of the FA stored in the internal DB.
