10.5.5.15 Routing area identification
The purpose of the routing area identification information element is to provide an unambiguous identification of routing areas within the GPRS coverage area.
The routing area identification is a type 3 information element with 7 octets length.
The routing area identification information element is coded as shown in figure 10.5.130/3GPP TS 24.008 and table 10.5.148/3GPP TS 24.008.
