Abstract

Current priority rules in Telephone Networks like EMLPP (EMLPP, Enhanced Multi-Level Precedence Pre-emption) indicate priority during call initiation. Thereto, successful location registration of the subscriber in the network is a pre-requisite. In case of traffic overload, external entities like VLR/SGSN (VLR, Visitor Location Register; SGSN, Serving GPRS Support Node) usually give precedence to home subscribers and any location update requests from roaming, mobile subscribers are rejected. That leads to call failure even for subscribers with EMLPP service. Traffic rejection poses a problem especially for so called high profile subscribers to whom roaming is major important.

Thereto, successful location registration of the subscriber in the network is a pre-requisite. In case of traffic overload, external entities like VLR/SGSN (VLR, Visitor Location Register; SGSN, Serving GPRS Support Node) usually give precedence to home subscribers and any location update requests from roaming, mobile subscribers are rejected. That leads to call failure even for subscribers with EMLPP service. Traffic rejection poses a problem especially for so called high profile subscribers to whom roaming is major important.

The following idea proposes a solution by using the IMSI (International Mobile Subscriber Identity) numbering scheme (Fig. 1). At location registration procedure, the only subscriber identification available at the MSC/VLR (MSC, Mobile Switching Center) is the subscriber's IMSI. The IMSI can provide the information whether this subscriber belongs to the same PLMN (PLMN, Public Land Mobile Network) as the MSC/VLR or a different PLMN, i.e. whether the subscriber is a roaming or a home subscriber. The MCC and MNC part (MCC, Mobile Country Code; MNC, Mobile Network Code) of the IMSI identifies the PLMN of the subscriber; the MSIN (MSIN, Mobile Subscriber Identification Number) identifies the mobile subs...
