All 3G and GSM specifications have a 3GPP specification number consisting of 4 or 5 digits. (e.g. 09.02 or 29.002). The first two digits define the series as listed in the table below. They are followed by 2 further digits for the 01 to 13 series or 3 further digits for the 21 to 55 series. The term "3G" means a 3GPP system using a UTRAN radio access network; the term "GSM" means a 3GPP system using a GERAN radio access network. (Thus "GSM" includes GPRS and EDGE features.) A specification in the 21 to 35 series may apply either to 3G only or to GSM and 3G. A clue lies in the third digit, where a "0" indicates that it applies to both systems. For example, 29.002 applies to 3G and GSM systems whereas 25.101 and 25.201 apply only to 3G. Most specs in all other series apply only to GSM systems. However, as the spec numbering space has been used up, this guide is more frequently broken, and it is necessary to examine the information page for each spec (see the table below) or to check the lists in 01.01 / 41.101 (GSM) and 21.101 (3G) for the definitive specification sets for each system and each Release.
所有3G和GSM规范具有一个由4或5位数字组成的3GPP编号。(例如:09.02或29.002)。前两位数字对应下表所列的系列。接着的两位数字对应01-13系列,或3位数字对应21-55系列。词"3G"意味着采用UTRAN无线接入网的3GPP系统,词"GSM" 意味着采用GERAN无线接入网的3GPP系统(因而,"GSM"包括GPRS和EDGE性能)。 21-35系列规范只用于3G或既用于GSM也用于3G。第三位数字为"0"表示用于两个系统,例如29.002用于3G和GSM系统,而25.101和25.201仅用于3G。其它系列的大多数规范仅用于GSM系统。然而当规范编号用完后,须查看每个规范的信息页面(见下表)或查看01.01 / 41.101 (GSM) 和21.101 (3G) 中的目录。 |
