Problems solved by technology

[0007] 1. Requires additional signaling procedures between CN and RAN, new messages and / or redefinition of existing messages
[0008] 2. The RAN needs to more or less randomly select one of the PLMNs to decode the NAS message

Embodiment Construction

[0036] Embodiments of the present invention will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like numbers refer to like elements throughout the drawings.

[0037] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0038] figure 1 An overview of a communication system 100 is shown, which includes a core network CN101 and a radio access network RAN102. exist figure 1 And in the following, the RAN will be described using an example from the GSM system, whereby the RAN comprises a Base Station Subsystem BSS 107 which in turn comprises a Base Transceiver Station 108 and a Base Station Controller BSC 109 . The combination of BTS and BSC is used in the GSM system, an...

Abstract

A mobile station (110) for use in a radio access network RAN ​​(102), the RAN being connected to a core network (101) in which one or more public land mobile networks PLMN (103, 104, 105). The mobile station (110) is configured to select one of the PLMNs (103, 104, 105) and is configured to communicate with its RAN (102) over radio link control RLC data blocks. The mobile station is configured to include the identification ID of its selected PLMN in the RLC data block, and to notify the RAN by including a reserved or predefined value in the length indication field of the RLC data block. (102) Notify that the ID of the selected PLMN exists in the RLC data block.

Description

technical field [0001] The present invention discloses a device and method for making a mobile station transmit information related to a selected PLMN. Background technique [0002] If the communication system includes a core network CN and a radio access network RAN, and both CN and RAN support the so-called multi-operator core network FULL-MOCN, that is, more than one PLMN in the CN, then as the mobile station MS (which also supports FULL-MOCN) is part of the process of connecting to its preferred public land mobile network PLMN in the core network, the radio access network RAN ​​(which connects the mobile station to the core network CN) needs to know the ID of the preferred PLMN, which is currently 4 8-bit long field. [0003] Currently, there is no mechanism for an MS to indicate its preferred PLMN ID to the RAN when accessing the PS domain (i.e., when connecting the MS to the CN), although in order to implement FULL-MOCN in the communication system, such a mechanism is...
