Description

Mobile terminal call signal processing by subscriber priority level

The present invention relates to a mobile terminal call signal processing method for each subscriber priority level applied to a mobile communication system and a computer-readable recording medium recording a program for realizing the same.

1 is a flowchart of a conventional mobile terminal call signal processing method.

As shown in the figure, set variable n to '1', set variable m to '1', set access probe variable P to '15' and set access probe sequence variable Q to '15' In step 101, the n-th access probe sequence Q is set (102), and the mobile terminal output Pt is set as the initial output Pt_int (103).

Thereafter, the mobile terminal transmits an outgoing signal to the base station using the m-th access probe P (104), and determines whether the mobile terminal has received a traffic channel assignment message from the base station and transmits an acknowledgment message (105). If the message is transmitted, the mobile terminal acquires a traffic channel and performs a call (106).

On the other hand, if the mobile terminal receives the traffic channel assignment message from the base station and transmits an acknowledgment message (105) and fails to send an acknowledgment message, the mobile terminal outputs the mobile terminal output Pt to the initial output Pt_int by a predetermined output step. Increase by (PWR_STEP), increase m by '1' (107), determine if the value of m is less than access probe variable P + '1' (108) and move if m is less than access probe variable P + '1' The terminal repeats the process of transmitting an outgoing signal to the base station using the access probe m, and if m is not less than the access probe variable P + '1', n is increased by '1' (109), where n is the access probe sequence If n is smaller than the access probe sequence variable Q + '1', the process of setting the access probe sequence n is repeated.

As described above, in the conventional mobile communication system, the access probe P and the access probe sequence Q are unique parameters, and fixed values are delivered to all mobile terminals in common through the paging channel, and all mobile terminals have the same access probe P and access. An outgoing signal was transmitted in the probe sequence Q.

Therefore, in the related art, even when the mobile terminal transmits an outgoing signal in the mobile communication system, the transmission output of the mobile terminal is not large enough, and even if the transmission output of the mobile terminal is large enough, the same access channel that the mobile terminal attempts to transmit from the specific mobile terminal is different. Since the same time slots are used, collisions are generated between the call signals, which reduces the probability of success.

Accordingly, the present invention devised to solve the above problems, the priority of the subscriber in order to give priority to the mobile terminal having a high priority when the mobile terminal requests a call from the base station in the mobile communication service area; SUMMARY OF THE INVENTION An object of the present invention is to provide a method of processing a mobile terminal call signal for each subscriber priority level, which allocates a priority to process a call signal of a subscriber mobile terminal, and a computer-readable recording medium recording a program for realizing the same.

4 is a flowchart illustrating a method for processing a mobile terminal call signal for each subscriber priority level according to the present invention, which illustrates a mobile terminal call signal processing method through static allocation of an access probe sequence value.

As shown in the figure, upon subscription, the mobile terminal stores the access probe sequence value according to the subscriber priority level (401), the home location register registers the mobile terminal, and stores the access probe sequence value (402). .

Thereafter, the mobile terminal turns on the power (403), the mobile terminal registers the location of the mobile terminal in the mobile communication network (404), and the mobile terminal retrieves the access probe sequence value in the mobile terminal (405).

Subsequently, the calling signal is attempted to set n to '1' (406), and the mobile station transmits the calling signal to the base station using the nth access probe sequence (407), and the mobile terminal allocates a traffic channel from the base station. After receiving the message and determining whether or not to transmit the confirmation message (408), if the mobile station acquires a traffic channel and performs a call (409), if it fails to send the confirmation message, it increases n to '1' ( In step 410, it is determined whether n is smaller than the searched access probe sequence value (411) and the process of repeatedly transmitting an outgoing signal to the base station using the n-th access probe sequence is repeated.

On the other hand, in the static allocation scheme as described above, in the mobile communication system, when a user applies for subscription, unique values such as a user number, an International Mobile Station Identity (hereinafter referred to as "IMSI"), an encryption key subscriber, and the like are registered. Will be allocated. These unique values are stored in a home location register or an authentication center, depending on the nature, and the same values are stored in the subscriber terminal.

In addition, when the access probe sequence (Q) value according to the subscriber priority is applied to the subscriber terminal, the unique value is input to the subscriber station, and the same value is stored in the home location register, so that the access probe sequence input when the mobile station transmits the originating signal to the base station. Attempt an access probe sequence by the value (Q).

Subsequently, the calling signal is attempted to set n to '1' (505), the mobile station transmits the calling signal to the base station using the nth access probe sequence (506), and the mobile terminal allocates a traffic channel from the base station. After receiving the message, it is determined whether the acknowledgment message has been transmitted (507). If the acknowledgment message is transmitted, the mobile terminal acquires a traffic channel to perform a call (508), and if n fails to transmit the acknowledgment message, n is increased to '1' ( In operation 509, the mobile terminal determines whether n is smaller than the found access probe sequence value (510) and repeatedly transmits an outgoing signal to the base station using the n th access probe sequence.

Meanwhile, the dynamic allocation method as described above stores the access probe sequence (Q) as a subscriber unique value at the same time as the terminal registration at the time of registration, and accesses the home location register with its own parameters, such as IMSI and home location register ID. Stores probe sequence (Q) values.

In addition, the access probe sequence (Q) value according to the service usage priority level of the subscriber is registered and managed in the home location register so that the mobile terminal attempts to access the base station to obtain an access channel through the visitor location register in the region. Receive a sequence (Q) value from a home location register.

In addition, when the registered mobile terminal enters the mobile communication service area, the mobile communication system performs a terminal registration procedure. At this time, the base station transmits a message to the specific terminal together with the overhead message and the mobile communication system parameter message received from the mobile communication system. The unique values are transmitted, and unique values for a specific terminal include IMSI, Temporary Mobile Station Identity (hereinafter referred to as "TMSI"), and the like.

The transmission of the access probe sequence (Q) value through the paging channel attempts the sequence by the access probe sequence (Q) value together with the TMSI value when performing the mobile terminal registration procedure.
