Description

How to register / change the handoff priority class in the mobile switching system

The present invention relates to a method of registering / changing a handoff processing class, and more particularly, to a service that allows a mobile mobile subscriber to change or register an individual's handoff rank before a call attempt.

In the related art, when a general subscriber in a call moves and enters another cell, the base station controller stops the handoff process if no available relay line is available and checks the available relay line during the handoff process. Send to The base station controller, which has received this message, does not perform handoff processing on the terminal, and when the mobile terminal does not handoff normally and the power level becomes “0”, the terminal on the call is released.

Also, in the wireless mobile communication, if the personal handoff ranking information is 0 level, if the relay line is not available, the handoff rank is searched among subscribers of 2nd and 1st class, and among the relay lines occupied by 2nd and 1st grade subscribers. By releasing one relay line and handing off a 0-level subscriber, the higher the rating, the better the service.

In addition, when the personal handoff ranking information is 1st class, the handoff ranking is searched among subscribers of 2nd class, and the relay line of one of the relay lines occupied by the 2nd class member is released and the 1st class member is handed off.

However, subscribers who do not wish to receive this service at all times have the disadvantage that it is difficult to change the handoff grade service again.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned shortcomings, and if a personal mobile subscriber wants to change / register a handoff priority, the handoff priority in a mobile communication switching system which directly changes and registers using a mobile subscriber's terminal. The purpose is to provide a method for registering / changing classes.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, with reference to the accompanying drawings, it will be described in detail a preferred embodiment of the present invention.

First, referring to FIG. 1, FIG. 1 is a block diagram of a mobile communication system for explaining an embodiment of a ranking handoff processing method, wherein each of the first, second, and Nth base stations 10-1, 10-2, ..., 10-n) wirelessly connects with a personal mobile subscriber in the area and requests authentication for use of the terminal.

The first, second, and N-th base station controllers 20-1, 20-2,... 20-n are connected to a plurality of base stations, and control the base stations to wirelessly receive signals from the base stations to receive the received signals. It controls the process of processing, one base station controller controls a plurality of base stations.

The first, second, and Nth mobile communication exchanges 30-1, 30-2, ..., 30-n are connected with a plurality of base station controllers, and one mobile communication exchange controls a plurality of base station controllers. .

Each visited subscriber management block 32-1, 32-2, ..., 32-n is located inside each of these multiple mobile switching centers to receive and temporarily store information of a plurality of subscribers. It acts like a base and, for example, if a temporarily registered subscriber has moved elsewhere, this subscriber information is destroyed, and if a new subscriber has entered this subscriber from the home location register (HLR) 40. Receive and store this information.

Each home location register 40 is in contact with each of the first, second, and Nth mobile communication exchanges 30-1, 30-2,..., 30-n, and each of the first, second, respectively. , Each visited subscriber management block 32-1, 32-2,... 32-n inside the N-th mobile communication exchange 30-1, 30-2,. It also sends and receives the subscriber's information, and also transmits and receives the subscriber's code and number and subscriber handoff priority according to the present application.

Referring to FIG. 2, a method of registering handoff by rank in a mobile communication system is as follows.

When a subscriber first registers or requests his or her personal information to register and correct his or her personal information through the terminal, the base station 10-1, 10-2, 10-n and the base station controller 20-1, 20 -2, ..., 20-n) to the corresponding mobile communication switch 30-1, 30-2, ... 30-n (step 200).

For example, the handoff class change request may send information by pressing the send key when digits of * + service code + # + registration / change request grades are sequentially.

The example change request described above will continue to be considered valid until released.

And, if you want to change or change the handoff class changes to the old way, only by changing the class in the same way, you can change the handoff class registration to the desired or old class.

If you want to change the handoff class of a call that is in service during a call, it is possible to suspend the call service that is currently in service and digit the example code to change the class only.

The timer is activated while special service information, i.e., priority registration / change request signal, is received (step 202).

It is determined whether the received signal can be processed, and it is determined whether the elapsed time of the timer exceeds the result processing time until the message is received (step 204).

If it times out, a failure message is sent to the calling subscriber. For example, the message Could not be timed out and try again is sent (step 206).

If the mobile communication exchange determines that the timeout has not been reached, the mobile communication exchange translates the number digited by the calling subscriber (step 208).

The number translation result is recognized as a handoff priority class registration / change request signal to determine whether handoff priority class registration / change is possible (step 210).

If it is determined in step 210 that registration / change of handoff priority information is impossible, a failure message, eg, the requested handoff priority request service is not registered, is left (step 212).

If it is determined in step 210 that the handoff priority level registration / change is possible, the handoff priority level is registered / changed and registered in the home location register 40 (step 214).

If it is determined in step 210 that the registration / change of the handoff priority information is possible, a success message, for example, “the requested handoff priority request service has been registered” is transmitted to the calling subscriber's mobile terminal (step 216).

In the case of using the above additional service, it is possible to use a shortcut key by using a number and alphabet currently assigned to the dial and using a function key in the terminal.

The terminal should display the number registered by the user on the terminal when activating the shortcut key.

As described above, in the wireless mobile communication, the handoff registration is conveniently performed by setting and changing the class for each individual or individual call at the terminal when registering and changing the handoff processing class. Provided is a method of registering / changing handoff class in a mobile switching center system.

The principles of the invention have been described above in connection with specific devices, which are described by way of example only, and are not limited to the spirit of the invention as described in the appended claims.
