A dispersion method and apparatus are provided.

As communication technology develops, the frequency with which mobile communication terminals, which have been mainly used for voice call service, is used for high-speed data services such as data download through Internet connection, etc., is increasing.

As a result of this service change, when the high-speed data service is performed by the IS-95A / B system, which is the second generation communication system centered on voice call service, the service speed is slow and the proper service cannot be provided.

Therefore, in order to compensate for this problem of the IS-95A / B system, the transition system of the third generation communication system, IMT-2000, that is, the CDMA2000-1x system, which is the 2.5 generation system, has the same service area, that is, the same as that of the IS-95A / B system. It is used in pseudo random noise (PN).

By performing a hash to encrypt with reference to the ECCL message first by the corresponding service channel of the CDMA2000-1x system is obtained.

In general, the IS-95A / B terminal is provided with a certain service by the IS-95A / B system, and the CDMA2000-1x terminal is provided with a certain service by the CDMA2000-1x system.

However, when the service subscriber uses only the CDMA2000-1x system or the IS-95A / B system, the number of service subscribers increases and the service channel of each system becomes saturated so that a smooth service cannot be provided.

Accordingly, the present invention has been made to solve various problems of the prior art, and is a service subscriber of a mobile communication system for distributing a CDMA2000-1x terminal to an IS-95A / B system by performing a superset hash. Its purpose is to provide a dispersion method and apparatus.

Another object of the present invention is to distribute a service subscriber in a mobile communication system for distributing an IS-95A / B terminal to a CDMA2000-1x system by setting up an IS-95A / B service channel and a CDMA2000-1x service channel in a CCL message. In providing a device.

Here, the base station 120 connects the first through N-th 2G terminals 110-1,..., 110 -N to the CDMA2000-1x system 122 to be serviced by the CDMA2000-1x system 122. Let's do it.

In addition, the base station 120 receives the IS-95A / B system (1) through the IS-95A / B system 124 to receive the first through N-th 1x terminals 100-1, ..., 100-N. 124).

Referring to the accompanying drawings, the operation of the subscriber distribution apparatus of the mobile communication system according to the present invention configured as described above is as follows.

First, an operation of distributing first to Nth 1x terminals to an IS-95A / B system will be described with reference to FIG. 2.

2 is a flowchart illustrating a method of connecting a 1x terminal to an IS-95A / B system according to the present invention.

The CDMA2000-1x system 122 of the base station 120 performs the overhead message at the time point for distributing the first to Nth 1x terminals 100-1, ..., 100-N to the IS-95A / B system. A message including a message for executing a superset hash function in the idle bit is transmitted to the first to N-th 1x terminals 100-1, ..., 100-N (S200).

In this case, the superset hash function is set in the first to N th 1x terminals 100-1,..., 100 -N.

Here, the superset hash function refers to an operation of hashing a sum of an Extended Cdma Channel List (ECCL) message and a CCL (Cdma Channel List) message received from the CDMA2000-1x system 122.

In addition, the overhead message includes system parameter information, service access information of the terminal, base station frequency information, information for international roaming, and information on neighboring base stations.

For example, if the service channel provided by the CDMA2000-1x system 122 is 1 to 3 service channels, and the service channel provided by the IS-95A / B system 124 is 4 to 6 service channels, the super A 1x terminal having obtained one service channel by the set hash is provided with the service by the CDMA2000-1x system 122.

Meanwhile, the 1x terminal having 6 service channels by the superset hash is provided with the service by the IS-95A / B system 124.

Here, only 1x terminal subscribers exist in the CDMA 2000 1x network, and the first to Nth 1x terminals 100-1, ..., 100-N are connected to the IS-95A / B system 124 by the superset hash. Since the service is provided by the IS-95A / B network, there are some IS-95A / B terminal subscribers and some 1x terminal subscribers.
