Device and method for information about PLMN ID
First Claim
1. A mobile station for use in a Radio Access Network (RAN), wherein the RAN is connected to a core network that comprises one or more Public Land Mobile Networks (PLMNs), the mobile station comprising:
- an interface to communicate with the RAN using Radio Link Control (RLC) data blocks;
a processor to;
choose one of said PLMNs when accessing a Packet Switched (PS) domain in the RAN;
include an identity (ID) of a chosen PLMN in an RLC data block; and
include a reserved or pre-defined value in a length indicator field of the RLC data block to inform the RAN that the RLC data block contains the ID of the chosen PLMN, wherein a value of 123 or 62 is used as the reserved or pre-defined value included in the length indicator field.

Abstract
A mobile station for use in a Radio Access Network, RAN, connected to a core network in which there is one or more Public Land Mobile Networks, PLMNs. The mobile station is arranged to select one of said PLMNs, and is arranged to communicate with its RAN by means of Radio Link Control, RLC, data blocks. The mobile station is arranged to include the identity, ID, of its selected PLMN in an RLC data block, and to inform the RAN of the presence of the ID of the chosen PLMN in the RLC data block by means of including a reserved or pre-defined value in the length indication field of the RLC data block.

5. A Control Node arranged to be part of a Radio Access Network (RAN), wherein the RAN is connected to a Core Network (CN) that comprises one or more Public Land Mobile Networks (PLMNs), the Control Node comprising:
-
an interface to receive Radio Link Control (RLC) data blocks from a mobile station in a cell in the RAN; a processor to; inspect a length indicator field in an RLC data block; identify a reserved or pre-defined value in the length indicator field, wherein the reserved or pre-defined value indicates that the RLC data block contains an ID of a PLMN selected by the mobile station from the one or more PLMNs, wherein a value of 123 or 62 is identified as the reserved or pre-defined value in the length indicator field; find and extract said ID in the RLC data block; and forward the ID to a node in the RAN or in the CN. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. A method performed by a mobile station comprising an interface and a processor, wherein the mobile station is connected to a Radio Access Network (RAN) and the RAN is connected to a core network comprising one or more Public Land Mobile Networks (PLMNs), the method comprising:
-
choosing one of said PLMNs when accessing a Packet Switched (PS) domain in the RAN; including an identity (ID) of the chosen PLMN in an RLC data block; including a reserved or pre-defined value in a length indicator field of the RLC data block to inform the RAN that the RLC data block contains the ID of the chosen PLMN, wherein a value of 123 or 62 is used as the reserved or pre-defined value in the length indicator field; and sending the RLC data block to the RAN. - View Dependent Claims (14, 15, 16)

17. A method performed by a Control Node comprising an interface and a processor, wherein the Control Node is part of a Radio Access Network (RAN) and the RAN is connected to a Core Network (CN) comprising one or more Public Land Mobile Networks (PLMNs), the method comprising:
-
receiving Radio Link Control (RLC) data blocks from a mobile station in a cell in the RAN; inspecting a length indicator field in an RLC data block; identifying a reserved or pre-defined value in the length indicator field, wherein the reserved or pre-defined value indicates that the RLC data block contains an ID of a PLMN selected by the mobile station from the one or more PLMNs, wherein a value of 123 or 62 is identified as the reserved or pre-defined value in the length indicator field; finding and extracting said ID in the RLC data block; and forwarding the ID to a node in the RAN or in the CN. - View Dependent Claims (18, 19, 20)
