Abstract
A telecommunications system and method is disclosed for enabling a General Packet Radio Service (GPRS) node, namely a Serving GPRS Support Node (SGSN) within a cellular network, to be able to handle requests for Location Services (LCS) for a GPRS mobile station (MS) in parallel to other existing transactions such as delivering short messages or engaging in session management activity, e.g., data call connection. A new LCS transaction type can be introduced in the Connection-Management (CM) sub-layer of GPRS in the SGSN and the GPRS MSs to handle requests for LCS in parallel to other offered services. LCS can be multiplexed together with other existing functions in GPRS by allocating a new Service Access Point Identifier (SAPI) to LCS within the Logical Link Control (LLC) sub-layer of the GPRS. Alternatively, when a common LLC SAPI is used between different CM-sublayer functions, then a different protocol discriminator (PD) can be allocated for LCS.

8. The telecommunications system of Claim 1, wherein said at least one additional transaction type is a session management transaction type, said mobile station and 25 said serving GPRS support node having an additional logical link control connection between said respective session management transaction types in order to establish a data call for said mobile station, said logical link control connection between said respective location service transaction types of said serving GPRS support node and said mobile station being established without disrupting said data call. WO 00/35236 PCT/US99/29319 -13
9. The telecommunications system of Claim 1, wherein said at least one additional transaction type includes a session management transaction type and a short message transaction type, said location service transaction type supporting location services 5 and additional services not supported by said session management transaction type or said short message transaction type
10. A telecommunications system for providing location services in parallel to session management and short message services within a General Packet Radio Service 10 (GPRS) system, said telecommunications system comprising: a radio link control sublayer within a mobile station and a serving GPRS support node in wireless communication with said mobile station, said radio link control sublayer transmitting data between said serving GPRS support node and said mobile station; a connection management sublayer within said serving GPRS support node and said 15 mobile station, said connection management sublayer having a session management transaction type, a short message transaction type and alocation service transaction type therein; and a logical link control sublayer within said serving GPRS support node and said mobile station, said logical link control sublayer providing connections between said session 20 management transaction types, said short message transaction types and said location service transaction types of said serving GPRS support node and said mobile stations, respectively, in parallel using said radio link control sublayer
11. The telecommunications system ofClaim 10, further comprising a physical 25 layer, a data link layer and an application layer within said serving GPRS support node and said mobile station, said radio link control sublayer, said connection management sublayer and said logical link control sublayer residing in said application layer.
