DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reserved line allocating method, and more particularly to a reserved line allocating method for allocating a line of a specific line number designated in a time division multiplex radio communication control apparatus.

[0002]

2. Description of the Related Art A conventional reserved line allocation system of this type is a system in which lines are allocated in the order of allocation request for a call requesting line allocation, and a line having an arbitrary line number is designated without specifying a specific line number. It is assumed that there are only calls that require assignment.

FIG. 4 is a block diagram showing an example of a conventional reserved line allocating method, FIG. 5 is a flowchart for explaining the operation in FIG. 4, and FIG. 6 is a diagram showing the configuration of a reserved memory in FIG.

[0004] Referring to FIG. 4, the reserved channel allocation method of this example is based on a radio communication control device 110 and mobile stations 101 and 1.
02.

The wireless communication control device 110 includes a signal transmitting / receiving device 11, a control unit 13, and a storage unit 14. The control unit 13 includes the communication control unit 1 and the line management unit 6
The storage unit 14 includes a reservation memory 3 and a line management memory 4 that stores whether all lines are free.
And

Next, the reservation memory 3 will be described with reference to FIG. The reservation memory 3 is a queue having a single-list structure of a first-in first-out (first-in first-out) system. Each node 3a, 3b,..., 3n stores a reservation number, a call number, and a next reservation number. ing.

Therefore, the reservation number of the node 3a is the first reservation number, and the reservation number of the node 3n is the last reservation number. The node 3n does not have the next reservation number and is "END".

Next, the operation of this embodiment shown in FIG. 4 will be described with reference to FIG.

For example, when a line assignment request is issued from the mobile station 101 to the communication control means 1 through the signal transmitting / receiving device 11, the communication control means 1 in the control unit 13 requests the line management means 6 to assign a line (step S400). .

The line management means 6 searches for a free line in the line management memory 4 (S401) and determines whether there is a free line (S402).

If NO in S402, that is, if there is no free line, the identification number of the call is registered at the end of the list in the reservation memory 3 in the storage unit 14 (S403).

When the signal transmitting / receiving device 11 receives a line release request from another mobile station in communication, the communication control means 1 receives the line releasing request from the signal transmitting / receiving device 11.
Requests the line management means 6 to release the line (S410).

Then, the line management means 6 checks whether the identification number of the call is registered in the list of the reservation memory 3 (S).
411).

If NO in S411, that is, if the call identification number is not registered, the line management means 6 releases the line in the line management memory 4 (S412).

If YES in S402, that is, if there is a free line, the line management means 6 allocates a line to the call. If YES in S411, that is, if the call identification number is registered,
A line is allocated to the first call in the list in the reservation memory 3 shown in (4) (S413).

Thereafter, the communication control means 1 transmits a channel assignment to the mobile station 101 and the mobile station 102 through the signal transmitting / receiving device 11.

[0017]

As described above, in the conventional reserved line allocation method, the released line is always allocated to the call stored at the head of the list in the reserved memory.

However, there is a first call requesting an arbitrary line number at the head of the list in the reserved memory, and a second call after designating a specific line number after the first call and waiting. If there is, the line number requested by the second call is allocated to the first call even if it is released first, so the second call must be further waited until the communication of the first call ends. become.

Therefore, there is a problem that a call designating a specific line number requires much longer line allocation time than other calls.

An object of the present invention is to store a reservation number in a specific reservation memory when a specific line number is designated, and to deal with a call determined from the reservation number stored in the specific reservation memory when the line is released. It is an object of the present invention to provide a reserved line allocation method that can reduce the time required for line allocation of a call designating a specific line by preferentially allocating lines irrespective of the order of the list in the reserved memory.

[0021]

According to the present invention, there is provided a time-division multiplexing radio communication control apparatus, in which a time-division multiplexing radio line is allocated and managed when there is no free line. A reservation memory for storing the identification numbers of the calls in the order of the line allocation request, a specific reservation memory for storing the reservation number of the call to be specified and awaiting, and a released line stored in the specific reservation memory. A reserved line allocation method is provided, comprising: line management means for preferentially allocating the released line to the corresponding call and deleting the corresponding reservation number from the specific reservation memory.

Further, the specific reservation memory has a two-dimensional array in which the carrier number and slot number of the line are suffixed, and stores the reservation number of the corresponding call at each intersection point. Is obtained.

Further, the time division multiplex radio communication control device includes a signal transmission / reception device, a control unit, and a storage unit, and the control unit includes communication control means and the line management means,
The storage unit includes the reservation memory, the line management memory, and the specific reservation memory, and when a line allocation request transmitted from a mobile station is issued to the communication control unit through the signal transmitting / receiving device, the communication control unit Requests the line management means to allocate a line, the line management means searches for a free line in the line management memory, and when there is no free line, registers the call identification number at the end of the list in the reserved memory,
Next, the line management means determines whether or not the call designates a line number. If the call is designated, the call reservation number is set at a position determined by the corresponding carrier number and slot number of the specific reservation memory. When the signal transmission / reception device receives a line release request from another mobile station in communication, the communication control unit requests the line management unit to release the line, and the line management unit releases the line. When it is determined that the call reservation number is not stored at the position of the specific reservation memory determined from the carrier number and the slot number, it is determined whether or not the call identification number is stored in the reservation memory. If not, a reserved line allocation method characterized by releasing the line is obtained.

Further, when the line management means searches for a free line in the line management memory, if there is a free line, a line is allocated to the call, and the line management means releases the carrier of the released line. When it is determined that the reservation number of the call is stored at the position of the specific reservation memory determined from the number and the slot number, the reservation number is deleted from the specific reservation memory, and the line of the line determined by the reservation number is determined. A reserved line allocation method characterized by performing allocation is obtained.
