Method and device for sending system information

Abstract

A method for sending system information comprises: a terminal receives a broadcast message from a network device, wherein the broadcast message comprises indication information for an system information (SI) and wherein that the indication information is for indicating that whether the SI is being broadcasted or not; and in case that the indication information indicates that the SI is not being broadcasted, the terminal sends a system information request to the network device for acquiring the SI.

What is claimed is: 
     
         1 . A method for acquiring system information (SI), comprising:
 obtaining, by a terminal, a bitmap, wherein the bitmap comprises at least one bit;   determining, by the terminal, whether a value of a bit of the at least one bit indicates that SI corresponding to the bit needs to be acquired by the terminal by sending a system information request; and   in response to determining that the SI corresponding to the bit needs to be acquired by the terminal by sending a system information request, initiating, by the terminal, a system information request to a base station for acquiring the SI corresponding to the bit.   
     
     
         2 . The method according to  claim 1 , wherein the bitmap is a latest bitmap. 
     
     
         3 . The method according to  claim 1 , wherein a change in the bitmap is not notified to the terminal via a paging message. 
     
     
         4 . The method according to  claim 1 , wherein obtaining the bitmap comprises:
 receiving a broadcast message from the base station, wherein the broadcast message comprises the bitmap.   
     
     
         5 . An apparatus for acquiring system information (SI), comprising:
 at least one processor; and   a non-transitory memory storing instructions, wherein the instructions, when executed by the at least one processor, cause the apparatus perform operations comprising:   obtaining a bitmap, wherein the bitmap comprises at least one bit;   determining whether a value of a bit of the at least one bit indicates that SI corresponding to the bit needs to be acquired by the apparatus by sending a system information request; and   in response to determining that the SI corresponding to the bit needs to be acquired by the apparatus by sending a system information request, initiating a system information request to a base station for acquiring the SI corresponding to the bit.   
     
     
         6 . The apparatus according to the  claim 5 , wherein the bitmap is a latest bitmap. 
     
     
         7 . The apparatus according to the  claim 5 , wherein the apparatus is not notified of a change in the bitmap via a paging message. 
     
     
         8 . The apparatus according to the  claim 5 , wherein obtaining the bitmap comprises:
 receiving a broadcast message from the base station, wherein the broadcast message comprises the bitmap.   
     
     
         9 . A non-transitory computer-readable medium having processor-executable instructions stored thereon for acquiring system information (SI), wherein the processor-executable instructions, when executed, facilitate:
 obtaining a bitmap, wherein the bitmap comprises at least one bit;   determining whether a value of a bit of the at least one bit indicates that SI corresponding to the bit needs to be acquired by sending a system information request; and   in response to determining that the SI corresponding to the bit needs to be acquired by sending a system information request, initiating a system information request to a base station for acquiring the SI corresponding to the bit.   
     
     
         10 . The non-transitory computer-readable medium according to  claim 9 , wherein the bitmap is a latest bitmap. 
     
     
         11 . The non-transitory computer-readable medium according to  claim 9 , wherein obtaining the bitmap comprises:
 receiving a broadcast message from the base station, wherein the broadcast message comprises the bitmap.
