Method for analyzing subscriber data received from an HLR in GSM MSC/VLR
First Claim
1. In a network according to a Global System for Mobile communication (GSM) standard, a method of receiving data concerning supplementary services in a mobile services switching center/visitor location register (MSC/VLR) which have been signalled via a GSM recommended protocol mobile application part (MAP) between a home location register (HLR) and MSC/VLR, where MAP contains sequences of containers for supplementary service dam, where respective containers include a parameter identifying the supplementary service to which the content of the container relates, together with service specific data, comprising the steps ofa) analyzing syntactically subscriber data received in MAP for identifying respective supplementary services,b) permitting access to the content of the container for an identified supplementary service,c) making the respective supplementary service analyze syntactically those data types which are included in the container in accordance with structures particular to the respective supplementary service, andd) storing data locally for each supplementary service in MSC/VLR.

Abstract
A method of receiving in a GSM-network data for supplementary services in MSC/VLR which have been signalled via the protocol MAP between HLR and MSC/VLR. MAP contains sequences of "containers" for supplementary services, where respective "containers" always include a parameter that indicates the service to which the contents of a respective container relate, together with the data that varies from service to service. This parameter is always located in the same position internally within the "container". The method includes a function whose purpose is to analyze syntactically subscriber data received in MAP, to the extent that respective supplementary services can be identified. When the correct supplementary service has been identified with the aid of the data type SS-code, it obtains access to the contents of the container. Respective supplementary services analyze syntactically those data types that are included in the container in accordance with a structure which is known only in a respective supplementary service. Data is then stored locally for each supplementary service in MSC/VLR.

4. requesting from the identified supplementary service release of the content of the container for use by said supplementary service, and analyzing internally within said supplementary service said content;
3. repeating steps B1-2 until all containers have been gone through and all containers have been delivered to respective the MSC/VLR receiving supplementary services, while discarding containers which do not correspond to a supplementary service. - View Dependent Claims (6, 8, 10, 11)

5. A method of receiving supplementary services data in a mobile switching center/visitor location register (MSC/VLR) from a home location register (HLR) in accordance with a Global System for Mobile (GSM) communications mobile application part (MAP) protocol, the method comprising the steps of:
-
analyzing a supplementary services code in a designated location in at least one of a plurality of containers contained within the MAP protocol; granting access to contents of each of said plurality of containers which have a designated supplementary services code; and copying container data corresponding to said designated supplementary services code into a MSC/VLR. - View Dependent Claims (7, 9)
