Service bearer congestion control method and device

Abstract

A service category congestion control method and device are provided. The method includes that: service request information is acquired, the service request information including information corresponding to a request for establishing a bearer of a target service initiated by a terminal in a connected mode and the service request information including a service category of the target service; service category barring information is acquired, the service category barring information including a barring parameter corresponding to the service category of the target service in the connected mode; and whether the terminal is barred from establishing the bearer of the target service belonging to the service category is judged according to the barring parameter.

1 . A service category congestion control method, executed by a terminal, and comprising:
 acquiring service request information, the service request information comprising information corresponding to a request initiated by the terminal in a connected mode for establishing a bearer of a target service and the service request information comprising a service category of the target service;   acquiring service category barring information, the service category barring information comprising a barring parameter corresponding to the service category of the target service in the connected mode; and   judging, according to the barring parameter, whether the terminal is to be barred from establishing the bearer of the target service of the service category.   
     
     
         2 . The method according to  claim 1 , wherein the barring parameter is a probability, and the method further comprises:
 acquiring a random number generated by the terminal for the target service; and   wherein the judging, according to the barring parameter, whether the terminal is to be barred from establishing the bearer of the target service of the service category comprises:   when the random number is larger than the probability, barring the terminal from establishing the bearer of the target service; or   when the random number is smaller than the probability, allowing the terminal to establish the bearer of the target service.   
     
     
         3 . The method according to  claim 1 , wherein the method is executed by an Access Stratum (AS) of the terminal, and
 wherein the acquiring service request information comprises:   receiving the service request information sent by a Non-Access Stratum (NAS) of the terminal; and   wherein the acquiring service category barring information comprises:   receiving the service category barring information broadcast by an access network device, the service category barring information comprising multiple service categories and barring parameters corresponding to the multiple service categories respectively.   
     
     
         4 . The method according to  claim 3 , further comprising:
 when it is determined that the terminal is barred from establishing the bearer of the target service according to the barring parameter, sending to the NAS, by the AS, indication information indicating that establishment of the bearer of the target service is barred.   
     
     
         5 . A service category congestion control method, executed by a network device, and comprising:
 acquiring service request information, the service request information comprising information corresponding to a request initiated by the terminal in a connected mode for establishing a bearer of a target service and the service request information comprising a service category of the target service;   acquiring service category barring information, the service category barring information comprising a barring parameter corresponding to the service category of the target service in the connected mode; and   judging, according to the barring parameter, whether the terminal is to be barred from establishing the bearer of the target service of the service category.   
     
     
         6 . The method according to  claim 5 , wherein the barring parameter is a probability, and the method further comprises:
 acquiring a random number generated by the terminal for the target service; and   wherein the judging, according to the barring parameter, whether the terminal is to be barred from establishing the bearer of the target service of the service category comprises:   when the random number is larger than the probability, barring the terminal from establishing the bearer of the target service; or   
       when the random number is smaller than the probability, allowing the terminal to establish the bearer of the target service. 
     
     
         7 . The method according to  claim 5 , wherein the network device is a core network device or an access network device. 
     
     
         8 . A terminal, comprising:
 a receiver, configured to acquire service request information, the service request information comprising information corresponding to a request for establishing a bearer of a target service initiated by a terminal in a connected mode and the service request information comprising a service category of the target service;   the receiver being further configured to acquire service category barring information, the service category barring information comprising a barring parameter corresponding to the service category of the target service in the connected mode; and   a processor, configured to judge whether the terminal is barred from establishing the bearer of the target service of the service category according to the barring parameter.   
     
     
         9 . The terminal according to  claim 8 , wherein the barring parameter is a probability, and the receiver is further configured to:
 acquire a random number generated by the terminal for the target service; and   wherein the processor is specifically configured to:   when the random number is larger than the probability, bar the terminal from establishing the bearer of the target service, or when the random number is smaller than the probability, allow the terminal to establish the bearer of the target service.   
     
     
         10 . The terminal according to  claim 8 , wherein the device is an Access Stratum (AS) of the terminal,
 wherein in order to acquire the service request information, the receiver is configured to:   receive the service request information sent by a Non-Access Stratum (NAS) of the terminal; and   wherein in order to acquire the service category barring information, the receiver is configured to:   receive the service category barring information broadcast by an access network device, the service category barring information comprising multiple service categories and barring parameters corresponding to the multiple service categories respectively.   
     
     
         11 . The terminal according to  claim 10 , further comprising:
 a sender, configured to, when it is determined that the terminal is barred from establishing the bearer of the target service according to the barring parameter, send, to the NAS, first indication information indicating that establishment of the bearer of the target service is barred.
