Abstract
Abstract A method for selecting a cell for a mobile station (MS) in a cellular telecommunications network, wherein the mobile station (MS) sends a radio station controller (BSC) measurement reports (6-4) comprising information (61, 631 . . . 63N) about the mobile station's serving cell and its neighbour cells. The mobile station or its subscriber is associated with at least one set of special cells called LSA cells. Information on the set of special cells is transferred to the radio station controller (BSC), and the mobile station (MS) at least participates in the transferring of information, preferably by sending an explicit list of its LSA cells or by including in at least one measurement report (6-4) a flag bit (62, 641 . . . 64N) indicating whether or not the cell in question is a special cell.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
A method for cell reselection for a mobile station in a cellular packet radio network comprising a radio station controller, the mobile station and the radio station controller having a capability to make decisions concerning cell reselection, the method comprising the steps of: sending from the mobile station to the radio station controller measurement reports comprising information about the mobile station's serving cell and its neighbour cells; and in response to fulfilment of a predetermined set of conditions, ordering the mobile station to at least partially surrender its capability to make decisions concerning cell reselection; associating the mobile station and/or its subscriber with at least one set of special cells; transferring information on said at least one set of special cells to the radio station controller wherein the mobile station at least participates in the transferring of information; and using the information on the special cells at the radio station controller for cell reselection when the mobile station has been ordered to at least partially surrender its capability to make decisions concerning cell reselection.
Claim 2
Independent Claim
174 words
A method for cell reselection for a mobile station in a cellular packet radio network comprising a radio station controller, the mobile station and the radio station controller having a capability to make decisions concerning cell reselection, the method comprising the steps of: sending from the mobile station to the radio station controller measurement reports comprising information about the mobile station's serving cell and its neighbour cells; and in response to fulfilment of a predetermined set of conditions, ordering the mobile station to at least partially surrender its capability to make decisions concerning cell reselection; associating the mobile station and/or its subscriber with at least one set of special cells; transferring information on said at least one set of special cells to the radio station controller wherein the mobile station at least participates in the transferring of information; and using the information on the special cells at the radio station controller for cell reselection when the mobile station has been ordered to at least partially surrender its capability to make decisions concerning cell reselection.
Claim 3
Dependent Claim
28 words
A method according to claim 1 , wherein the mobile station sends the radio station controller at least one explicit message which indicates the set of special cells.
Claim 4
Dependent Claim
35 words
A method according to claim 1 , wherein the mobile station indicates to the radio station controller in at least one measurement report indicating whether or not the cell in question is a special cell.
Claim 5
Dependent Claim
22 words
A method according to claim 3 , wherein the mobile station performs the indication only seldom, preferably once for each reported cell.
Claim 6
Dependent Claim
46 words
A method according to claim 1 , wherein the mobile station sends the radio station controller an indication that the set of special cells exists; and the radio station controller requests and receives the set of special cells from another network element, preferably an SGSN node.
