Abstract

PROBLEM TO BE SOLVED: To facilitate the management of a resource by automatically changing constitution information of a control part based on mounting information from respective cards. SOLUTION: When power is supplied, the card is initialized with the respective cards of a transmission/reception amplification part 11, a radio part 12 and a base band processing part 13 in a base station 1 and mounting information of the cards are informed to a control part 16. The control part 16 updates mounting information of the cards of constitution information, which are held, and starts an operation when the card of minimum constitution which is required for the operation is mounted. When it is not mounted, an alarm is outputted and the operation is not started until the alarm is released. When another card is added after the operation terminates, only the added card is initialized and a similar processing is repeated. A setting or change processing on mounting information of the cards of the respective parts from outside is eliminated, the initialization of all the cards is eliminated when the card is added and equipment constitution can easily be changed.

Description

DETAILED DESCRIPTION OF THE INVENTION

The mounting information of the card of each unit is held, and based on this information, the resource allocation of each card is controlled in call processing such as outgoing / incoming.

[0004] Hereinafter, a card mounting management method in a conventional base station apparatus will be described with reference to a flowchart of FIG.

First, before starting the apparatus, configuration information is input to the control unit from an external apparatus such as an exchange control station by an operator's operation (ST401). Then, the respective cards of the transmission / reception amplification unit, the radio unit, and the baseband processing unit perform initialization processing of the own card (ST402).

Next, the control unit is notified of the mounting information of each card (ST403), and the control unit matches the mounting information notified from the card with the part related to the card mounting information of the configuration information input from the outside. It is determined whether or not (S
T404), if they match, operation is started (ST40)
5).

If they do not match, an alarm is output to the switching control station (ST406). In this case, operation cannot be started unless the alarm is released.

After the operation (ST407), if the configuration is changed (ST408), for example, a card is hot-plugged, after the changed configuration information is input (ST409), ST4 is entered.
The process from 02 is repeated.

As described above, the conventional communication device starts operation after receiving configuration information from the outside and comparing it with the mounting information notified from the card.

The control section 16 is connected to each section via a bus, and controls each section based on configuration information of the apparatus. Then, the control unit 16 holds the mounting information of the card of each unit as one of the configuration information of the device, and allocates the resources of each card in the call processing such as outgoing / incoming based on this.

Hereinafter, a card mounting management method in the base station apparatus of the above embodiment will be described with reference to the flowchart of FIG.

First, when power is input, each card of the transmission / reception amplification unit 11, the radio unit 12, and the baseband processing unit 13 performs initialization processing of its own card (ST20).
1), the mounting information of each card is notified to the control unit 16 (S
T202), the mounting information part of the card of the configuration information held in the control unit 16 is changed (ST203).

Then, the control unit 16 determines whether or not a card having a minimum configuration necessary for operation is mounted (S16).
T204), if mounted, operation starts (ST2)
05).

If not, an alarm is output to the switching control station 3 (ST206). In this case, operation cannot be started unless the alarm is released.

After the operation is completed (ST207), when the configuration is changed, for example, by hot-inserting a card (ST20).
8) Initialization is performed on the added card (ST)
209), and repeat the processing from ST202.

As described above, by automatically changing the configuration information of the control unit based on the notification of the mounting information from each card, it is not necessary to externally reset the mounting information of the card of each unit. Can be.
