Output to Thus, a communication path from the terminal 101 to the network 103 is established. From this point onward, the call control with the higher layer starts the communication with the destination of the terminal 101.

- the radio resource control means 107 specifies the signal processing card to be released, and causes the signal processing means 106 to release the corresponding call.
- the number of resources used for the 4th signal processing card 106 d is only 6 for packet A calls, and 26 are free. Therefore, the unrestricted digital call 203 is assigned to the fourth signal processing card 106 d with the smallest number of resources used.
- Figure 5 shows the state when a packet B call occurs next to the assignment in Figure 3.
- the positions of resources for one call do not have to be continuous in the signal processing card.
- the voice call 2 0 4 of the third signal processing card 1 0 6 c is released from the state shown in FIG. 3, it is not considered that there are 2 free resources for 1 resource and 2 2 resources. Resource 2 3 It may be considered that there is one free resource.

- the load allocation process is performed for resource allocation when there are continuous resources and bucketable B calls can be allocated, and if not, efficiency is emphasized Can be changed to Therefore, if there are 2 2 free resources, it is judged that the traffic is low and allocation is performed by selecting a load distribution method. Furthermore, as an algorithm emphasizing efficiency, the method of assigning a new call to the signal processing card with the maximum utilization similar to this embodiment and the maximum size of free resources in the signal card are the smallest (the number of required resources is It is difficult to assign many calls) There is a method of assigning new calls to a signaling card.
- the threshold for switching (a) and (b) is dynamically increased or decreased, the effect of enabling control according to the time zone or the position of the base station can be obtained.
- the threshold is set to 1
- this embodiment is smaller than the threshold of 16 in this embodiment. Load distribution can be performed when there is little space.
- the present invention is also applied to the case where the number of signal processing cards and the number of resources in the signal processing cards are different for each signal processing card, and similar effects can be obtained easily by analogy.
- the present invention is also applicable to the case where the number of call types that can be accommodated in the base station 102 and the required number of resources for each call type are different.
- the radio resource monitoring means 1 0 9 changes the resource allocation method by the radio resource control means 1 0 7 to 3 methods according to the state of the signal processing means 1 0 6 and loads during low traffic Call allocation processing that depletes the resources of the card with the highest utilization as much as possible during high traffic By doing this, it is possible to achieve load distribution among the signal processing cards by using resources with high efficiency and without causing call loss as much as possible.
- the block configuration diagram is the same as FIG. 2 of the first embodiment.
- the signal processing card containing the common channel fails and communication of the common channel becomes impossible, unless free resources sufficient to accommodate the common channel are secured apart from the common channel always assigned. Therefore, in the present embodiment, an algorithm for the base station to secure resources for evicting the common channel is shown.
- the required number of resources for common channel is common_ch.
- common-ch is fixed at eight. The names of other variables or constants use the same names as in the first embodiment.
- FIG. 6 is a flow chart showing an algorithm of the present embodiment.
- an algorithm hereinafter referred to as an allocation card search algorithm
- an allocation card search algorithm for finding an optimum power mode is operated first in step ST501 regardless of the presence or absence of a common channel.
- the switching algorithm shown in the first embodiment is used as the assignment card search algorithm. Note that it is possible to use a method that does not consider other common channels as an allocation card search algorithm.
- step ST 502 it becomes new_call vacancy [i] (number of free resources Depending on the number of cards (the number of resources is less than the required number of resources for new calls), the selection method of the signal processing card to be assigned is determined. In the case of 0 cards, it can not be assigned to any card, so the result of step ST501 (not assignable) is taken as the result of this flow as it is, and it is considered as a call loss (ST503). On the other hand, if there are two or more signal processing cards that can be assigned except for the signal processing card that accommodates the common channel, even if a new call is assigned to any signal processing card, it will be evicted at the time of common channel failure. We can secure the destination. Therefore, in this case, it is allocated to the signal processing card searched by the allocation card search algorithm, and the result of step ST501 becomes the result of this flow as it is (ST506).
- the assignment card search algorithm differs from the algorithm of the present embodiment in the case where the assignable signal processing card in step ST504 has a signal processing card in which a common channel is accommodated, and one other card. At this time, if a call is assigned to a card that does not contain the common channel, and the available resources become less than the required number of resources of the common channel, the resources of the common channel can not be evicted.
- the signal of the one not containing the common channel is assumed to be a new call.
- Determine whether it is possible to evict a common channel when assigned to a processing card (assuming that the signal processing card number is n). Specifically, (vacancy [n] common common_ch + new_call) holds, that is, the number of free resources before allocation of another card is larger than the sum of the required resources of the common channel and the required resources of the new call. It is possible to assign to the n-th signal processing card for the first time (ST 506). Otherwise, resources can not be assigned to cards that do not contain common channels, so a new call is assigned to a signal processing card that contains common channels (step ST 505).
- step ST 501 it is determined in step ST 501 that it is the optimum allocation destination. Regardless of whether the n-th signal processing card accommodates the common channel, the assignment destination is determined. However, if the signal processing card containing the common channel is judged as the optimum allocation destination in processing 501, the allocation may be performed as it is. Even when this determination is added to the flow, the same effect as this embodiment can be obtained.
- reference numerals 1 0 6 a to 1 6 6 d denote first signal processing cards 1 0 1 a to 4 th signal processing cards 1 0 6 d, respectively.
- 4th signal processing card 1 0 Number of unrestricted digital: 3 resources, voice: 6 resources, bucket A: 2 resources 1 of the free resources 1 1 6 d and the number of free resources 2 1 (common channel: 8 resources, unrestricted digital: 3 resources used) of the first signal processing card 1 0 6 a can be assigned.
- the number of free resources for both the first signal processing card 1 0 6 a and the 4th signal processing card 1 0 6 d is (the required number of resources for the packet B call to be protected is 1 6 + Since it is smaller than the required number of resources of the new call 6), the fourth signal processing card 1 0 6 d with a small number of available resources is judged to be optimal (step ST 5 0 1 in FIG. 6).
- step S T 502 in FIG. 6 there are two cards that can be assigned including the first signal processing card 1 0 6 a containing the common channel, so the process proceeds to step S T 5 04.
- the remaining resources of the fourth signal processing card 106d are 11 and less than the sum of the required number of resources of the common channel 8 and the required number of resources of the new call. Therefore, if it is assigned to the fourth signal processing card 1 0 6 d, the resource ejection of the common channel of the first signal processing card 1 0 6 a can not be performed, so in FIG. Then, the process proceeds to step ST505, where an assignment is made to the first signal processing card 106a.
- FIG. 8 shows the assignment method when voice call 7 0 1 and packet A call 7 0 2 and 7 0 3 sequentially occur after the assignment shown in Fig. 6 is performed.
- the required number of resources for packet A call 6 and the required number of resources for common channel: 8.
- the fourth signal processing card 1 0 6 d is determined to be the optimum assignment destination by the assignment card search algorithm in step S T 501.
- the number of free resources of the fourth signal processing card 1 0 6 d is smaller than the sum of the required number of resources of the new call and the common channel, it is judged as Yes in step ST 504 and step ST 5 Proceed to step 05, and assign to the first signal processing card 1 0 6 a.
- the required resource card for the new call is the fourth signal processing card 1 It becomes one sheet of 0 6 d, and in FIG. 6, it is judged as “other” in step ST 502, and the process proceeds to step ST 506. Therefore, although the number of vacant resources of the fourth signal processing card 106d is smaller than the sum of the number of required resources of the new call and the common channel, allocation is performed to the fourth signal processing card 106d.
- the present invention is also applied to the case where the number of signal processing cards and the number of resources in the signal processing cards are different for each signal processing card, and similar effects can be obtained easily by analogy.
- the present invention is also applicable to cases where the number of call types that can be accommodated in the base station 102, the required number of resources for each call type, and the number of resources are different.
- the signal processing card accommodating the common channel fails. It will be possible to accommodate common channel resources on other signal processing cards, which will have the effect of enabling stable operation of the base station.
- the call to be protected is set first, the resource allocation method is changed according to the resource status of each card, load distribution is performed at low traffic, and card resource with high usage as much as possible at high traffic.
- the resources of the common channel can be stored if the signal processing card accommodating the common channel fails. It becomes possible to accommodate other signal processing cards, and the effect of enabling stable operation of the base station is obtained.
- the resource allocation method of a radio base station according to the present invention can be applied to a resource management scheme in which resources in a device are appropriately allocated in a radio base station that accommodates terminals that perform radio communication.
