1. A base station comprising:
- a memory having stored thereon instructions; and
a controller configured to process the instructions to;
control a connection between the base station and a mobile relay node, installed in a vehicle, for providing a user equipment with access to a communication system via a cell operated by the mobile relay node, andobtain an indication of whether or not the cell is a mobile cell from the mobile relay node, and, when the cell is a mobile cell, provide, to a location services server comprising at least one of an Enhanced Serving Mobile Location Center (E-SMLC) and a Secure User Plane Location (SUPL) Location Platform (SLP), information indicating that the cell is a mobile cell, as a part of a location positioning protocol procedure with the location services server.

Abstract
A communication node provides information relating to a location of a user device in a communication system. The communication node associates with a relay node for providing the user device with access to the communication system via a cell operated by the relay node. The communication node obtains an indication of whether or not the cell is configured as a mobile cell and provides, when the cell is configured as a mobile cell, information indicating that the cell is configured as a mobile cell to a further communication node.

10. A location services server comprising:
-
a network interface which receives, from a location services client, a request for positioning a target user device, the target user device being served by a mobile relay node installed in a vehicle; a memory having stored thereon instructions; and a controller configured to process the instructions to; identify a cell in which the target user device is located, respond to the request for positioning the target user device by initiating a location positioning protocol procedure, receive a cell identifier when the mobile relay node associates with the locations services server in response to a request sent by the location services server to the mobile relay node, determine, based on the received cell identifier, whether or not the identified cell is a mobile cell as part of the location positioning protocol procedure, and upon determination that the identified cell is a mobile cell, initiate a procedure to determine a position of the mobile relay node that operates the cell in which the target user device is located. - View Dependent Claims (11, 12, 13, 14, 15, 16)
