    • The invention comprises a method for a mobile terminal (1010) to register to a generic access node controller, GANC (1030) in a Circuit Switched Services over Long Term Evolution using Generic Access Network, CSOLTEVGAN architecture. In current procedures for roaming, the mobile terminal (1010) receives an address to a serving GANC (1030) in the same VPLMN from a default GANC (1050) in the HPLMN, This procedure results in a lot of signaling towards the default GANC (1050). The current invention overcomes this problem by adapting the mobile terminal (1010) to determine system information about the E-UTRAN cell by which the mobile terminal (1010) is served and to build a FQDN string based on the system information. This FQDN string is sent to a DNS server (1060) which resolves it to an IP address to a GANC (1030) located in the same VPLMN as the mobile terminal (1010). This IP address is used by the mobile terminal (1010) to connect and register itself to the GANC (1030).
    • 本发明包括一种用于移动终端(1010)在使用通用接入网络CSOLTEVGAN架构的长期演进的电路交换服务中向通用接入节点控制器GANC(1030)注册的方法。 在当前的漫游过程中,移动终端(1010)从HPLMN中的默认GANC(1050)向相同VPLMN中的服务GANC(1030)接收地址,该过程导致大量向默认GANC( 1050)。 本发明通过使移动终端(1010)适应确定关于移动终端(1010)所服务的E-UTRAN小区的系统信息并且基于系统信息构建FQDN串来克服这个问题。 该FQDN字符串被发送到DNS服务器(1060),其将其解析为位于与移动终端(1010)相同的VPLMN中的GANC(1030)的IP地址。 移动终端(1010)使用该IP地址将其自身连接并注册到GANC(1030)。
