Communication control apparatus and method of controlling same

Abstract

If a request for communication-band allocation control that is based upon narrowband QoS control is issued during execution of communication-band allocation control by an access point based upon broadband QoS control, a response is issued to instruct that the request be issued again following elapse of a stipulated time. If communication-band allocation control that is in progress ends and a request for communication-band allocation control is issued again following elapse of the stipulated time, then this communication-band allocation control is executed.

1 . A method of controlling a communication control apparatus, comprising the steps of:
 executing communication-band allocation control in accordance with a request from a communication apparatus; and   controlling in such a manner that until communication-band allocation control based upon a request from a first communication apparatus ends, the start of communication-band allocation control based upon a request from a second communication apparatus is delayed.   
   
   
       2 . The method according to  claim 1 , wherein communication-band allocation control based upon a request from the first communication apparatus is communication-band allocation control for performing communication-band allocation based upon network resource management of a first range, and communication-band allocation control based upon a request from the second communication apparatus is communication-band allocation control for performing communication-band allocation based upon network resource management of a second range different from the first range. 
   
   
       3 . The method according to  claim 2 , wherein communication-band allocation control based upon a request from the first communication apparatus is performed based upon control of a management apparatus that controls the network resources of the first range. 
   
   
       4 . The method according to  claim 1 , wherein end of the communication-band allocation control based upon a request from the first communication apparatus is at least completion of allocation of the communication band or time-out of a timer that measures delay time. 
   
   
       5 . The method according to  claim 3 , wherein end of the communication-band allocation control based upon a request from the first communication apparatus is recognized by a command for setting up the communication band from the management apparatus. 
   
   
       6 . The method according to  claim 1 , wherein at said control step, a response to a request from the second communication apparatus is transmitted, said response instructing that a request is to be issued again following elapse of a stipulated time. 
   
   
       7 . The method according to  claim 6 , wherein the stipulated time is a time obtained by adding a protect time to a time required for completion of the communication-band allocation. 
   
   
       8 . The method according to  claim 6 , wherein at said control step, in a case where a communication-band allocation request has been issued by a third communication apparatus, a command is issued so as to issue the request again upon elapse of the stipulated time if the stipulated time has not elapsed. 
   
   
       9 . A communication control apparatus comprising:
 execution device adapted to execute communication-band allocation control in accordance with a request from a communication apparatus; and   control device adapted to for control in such a manner that until communication-band allocation control based upon a request from a first communication device ends, the start of communication-band allocation control based upon a request from a second communication device is delayed.   
   
   
       10 . The apparatus according to  claim 9 , wherein communication-band allocation control based upon a request from the first communication apparatus is communication-band allocation control for performing communication-band allocation based upon network resource management of a first range, and communication-band allocation control based upon a request from the second communication apparatus is communication-band allocation control for performing communication-band allocation based upon network resource management of a second range different from the first range. 
   
   
       11 . The apparatus according to  claim 10 , wherein communication-band allocation control based upon a request from the first communication apparatus is performed based upon control of a management apparatus that controls the network resources of the first range. 
   
   
       12 . The apparatus according to  claim 9 , wherein end of the communication-band allocation control based upon a request from the first communication apparatus is at least completion of allocation of the communication band or time-out of a timer that measures delay time. 
   
   
       13 . The apparatus according to  claim 11 , wherein end of the communication-band allocation control based upon a request from the first communication apparatus is recognized by a command for setting up the communication band from the management apparatus. 
   
   
       14 . The apparatus according to  claim 9 , wherein said control device transmits a response to a request from the second communication apparatus is transmitted, said response instructing that a request is to be issued again following elapse of a stipulated time. 
   
   
       15 . The apparatus according to  claim 14 , wherein the stipulated time is a time obtained by adding a protect time to a time required for completion of the communication-band allocation. 
   
   
       16 . The apparatus according to  claim 14 , wherein in a case where a communication-band allocation request has been issued by a third communication apparatus, said control device issues a command such that the request will be issued again upon elapse of the stipulated time if the stipulated time has not elapsed. 
   
   
       17 . A program for causing a computer to execute the method of controlling a communication control apparatus set forth in  claim 1 , said program being recorded on a computer-readable recording medium. 
   
   
       18 . A computer-readable recording medium on which has been recorded a program for causing a computer to execute the method of controlling a communication control apparatus set forth in  claim 1 .
