0348 POR & SMS-PP Response 数据分析

 

3GPP TS 03.48 V8.8.0.doc 这份文档中的东西很多，分量很足！(published in 2001-12)

 

 

• Response Package structure:
  

 

 

Element	Length	Comment
Response Packet Identifier (RPI)	1 octet	Identifies a Response Packet.（响应报文标识）
Response Packet Length (RPL)	variable	Indicates the number of octets from and including RHI to the end of Additional Response data, including any padding octets required for ciphering. （响应报文长度）
Response Header Identifier (RHI)	1 octet	Identifies the Response Header.（响应报头标识）
Response Header Length (RHL)	variable	Indicates the number of octets from and including TAR to the end of the RC/CC/DS. （响应报头长度）
Toolkit Application Reference (TAR)	3 octets	This shall be a copy of the contents of the TAR in the Command Packet. （命令包中的TAR）
Counter (CNTR)	5 octets	This shall be a copy of the contents of the CNTR in the Command Packet. （命令包中的CNTR）
Padding counter (PCNTR)	1 octet	This indicates the number of padding octets used for ciphering at the end of the Additional Response Data.（）
Response Status Code Octet	1 octet	Codings defined in Table 5.（响应状态值）
Redundancy Check (RC冗余验证), Cryptographic Checksum (CC密码验证) or Digital Signature (DS数字签名)	variable	Length depending on the algorithm indicated in the Command Header in the incoming message. A typical value is 4 to 8 octets, or zero if no RC/CC/DS is requested.（Request命令报头中密钥长度）
Additional Response Data	variable	Optional Application Specific Response Data, including possible padding octets used for ciphering.（响应内容）

•  MO Response Structure:
  

 

 

SMS-REPORT specific elements	Generalised Response Packet Elements (Refer to Table 3)	Comments
UDL		Indicates the length of the entire SMS
UDHL	='02'	The first octet of the content of the SMS itself. Length of the total User Data Header, in this case, includes the length of IEIa + IEIDLa + IEDa.
IEIa	RPI= '71'	Identifies this element of the UDH as the Response Packet Identifier. This value is reserved in TS 23.040 [3].
IEIDLa	='00'	Length of this object, in this case the length of IEDa alone, which is zero, indicating that IEDa is a null field.
IEDa		Null field.
SM (8 bit data)	Length of Response Packet	Length of the Response Packet (RPL), coded over 2 octets, and shall not be coded according to ISO/IEC  7816-6 [8]. (see note)
	Response Header Identifier	(RHI) Null field.
	Length of the Response Header	Length of the Response Header (RHL), coded over one octet, and shall not be coded according to ISO/IEC 7816-6 [8].
	TAR to RC/CC/DS elements in the Response Header	The remainder of the Response Header.
	Secured Data	Additional Response Data (optional), including padding octets.
