Provision of short message services
First Claim
1. A method in a Home Location Register for Short Message Services (SMS) provisioning in a system including a Message Center (MC), and a Mobile Switching Center-Visitor Location Register (MSC-VLR), the method comprising the steps of:
- receiving a Registration Notification (REGNOT) message, containing address information associated with a mobile station (MS), from the MSC-VLR, storing a SMS address and Mobile Switching Center Identification (MSCIN) of the MS;
comparing a country code in the MSCIN with a country code in a calling party address of the MC;
determining whether the MC and the MSC share a common point code scheme;
selectively populating a SMS Request Return Result (smsreq) relative to said REGNOT message with a common point code from the SMS address if the MSC and MC share the same point code schemes or populating said smsreq with the MSCIN if the MSC and MC do not share the same point code scheme; and
forwarding said smsreq to said MC.

Abstract
This invention relates to a method and apparatus to provide Short Message Services (SMS) provisioning when different SS7 signaling networks are in use. The method can be used when mobile units are roaming in a SS7 network different than the MS home network, and when the MS is roaming inside or outside of its SS7 type of network.
The HLR, which includes a memory for storing a database of point code schemes and country codes, also stores all location data for the MSC including the SMS Address and the MSCIN. The HLR analyzes the SMS Address to determine the nationality of the MSC. The HLR compares the MSC'"'"'s REGNOT point code and MSCIN country code with the country code in the MC'"'"'s SMSREQ calling party address to determine whether the MC and MSC point codes are the same. If they are the same, the smsreq is populated with the common point code from the SMS Address. If not the same, the smsreq is populated with the MSCIN parameter.

11. A home location register (HLR) in a system further comprising a Messaging center (MC), a Mobile Switching Center, the HLR comprising:
-
a database for storing a Short Message Service address and Mobile Switching Center Identification (MSCIN) of a Mobile Station;
receiver means for receiving a request from said Messaging Center to deliver a SMS message to said MSC and for receiving a Registration Notification (REGNOT) message from the MSC-VLR containing address information associated with a mobile station (MS), means for comparing a country code in the MSCIN with a country code in a calling party address of the MC;
means for determining whether the MC and the MSC share a common point code scheme;
means for selectively populating a SMS request response (smsreq) relative to said REGNOT message with a common point code from the SMS address if the MSC and MC share the same point code schemes or populating said smsreq with the MSCIN if the MSC and MC do not share the same point code scheme; and
means for forwarding said smsreq to said MC.
