10.2.15.
Record Opening Time
这个字段包含了记录打开时的时间戳(具体的格式参考3GPP TS 32.005)。 10.2.16.
Record Sequence Number
这个字段记录了部分话单的相应序号，把某个特定的承载连接的从PDG产生的部分话单关联起来(特性与 Charging ID 和PDG地址相同)。如果承载连接只产生一个PDG话单，就没有记录序列号。 10.2.17.
Record Type
这个字段标识了记录类型，比如：S-CDR, G-CDR, M-CDR, S-SMO-CDR 及 S-SMT-CDR，WLAN-CDR。 10.2.18.
Served IMSI
这个字段包含了被使用的国际移动用户识别码(IMSI)。 该字段用来描述 参与被记录的交易的移动用户，比如终端发起的承载中的主叫用户。IMSI的格式在3GPP TS 23.003 有所定义。 10.2.19.
Served MSISDN
这个字段包含了被使用的移动台(MS)的ISDN号码(MSISDN)。 该字段用来描述 参与被记录的交易的移动用户。 MSISDN的格式在3GPP TS 23.003中有所定义。 10.2.20.
Served PDP Address(WLAN UE remote IP address)
这个字段包含了被使用的IMSI的Remote IP地址。这是网络层的IP V4或IP V6地址。每个PDP类型的地址是被临时分配或永久分配的。除了PDP类型是PPP并且使用动态PDP地址时，该参数都出现。 10.2.21.
Served IMEISV
这个字段包含了终端设备的国际移动设备识别码和软件版本(IMEISV)。IMEISV的格式在3GPP TS 23.003 有所定义。 10.2.22.
WLAN Session ID
这个字段是WLAN会话的标识，用于关联WLAN产生的计费信息和PDG产生的计费信息。

11. 话单的ASN.1描述
11.1.
PDG输出WLAN-CDR的ASN.1 定义
Within the current GSM 12-series of specifications the ASN.1 definitions are based on ISO8824 (90) / X.208 (88), which has been superseded by ISO8824-1 (94) / X.680 (94). This newer version not only includes new features but also removes some that were present in ISO8824 (90) / X.208 (88) .
Where possible, the GPRS work would be based on those ASN.1 features to both. However, where necessary, the new features in ISO8824-1 (94) / X.680 (94) be used in some places. ISO8824 (90) / X.208 (88)features that are no longer in ISO8824-1 (94) / X.680 (94) will not be used.
