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.
Claims22
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, and
- obtain 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.
The base station according to claim l wherein the controller is further configured to process the instructions to provide the information indicating that the cell a mobile cell to the location services server via a mobility management entity.
A mobile relay node, installed in a vehicle, the mobile relay node comprising:
- a memory having stored thereon instructions;
- and
- a controller configured to process the instructions to:
- control communications between the mobile relay node and a base station and between the mobile relay node and a user equipment,
- perform registration between the mobile relay node and the base station,
- keep track of the user equipment via at least one cell operated by the mobile relay node, and
- provide, to a location services server that comprises 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 at least one cell is a mobile cell, as part of a location positioning protocol procedure,
- wherein the controller is further configured to process the instructions to provide the information, indicating that the at least one cell is a mobile cell, in response to the mobile relay node receiving a request, via the base station, to provide information relating to the location of the user equipment.
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.
A method of a base station operating in a communication system, the method comprising:
- associating with a mobile relay node, installed in a vehicle, that provides a user device with access to the communication system via a cell operated by the relay node;
- obtaining, from the mobile relay node, an indication of whether or not the cell operated by the mobile relay node is a mobile cell;
- and
- when the cell operated by the mobile relay node is configured as a mobile cell, providing, to a location services server that comprises 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 operated by the mobile relay node is a mobile cell, as part of a location positioning protocol procedure with the location services server.
A method of a mobile relay node, installed in a vehicle and operating in a communication system, the method comprising:
- associating with a base station;
- and
- providing, to a location services server that comprises 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 at least one cell operated by the mobile relay node is a mobile cell, as part of a location positioning protocol procedure,
- wherein the providing comprises providing the information indicating that the at least one cell is a mobile cell in response to the mobile relay node receiving a request, via the base station, to provide information relating to the location of a user equipment.
A method of a location services server operating in a communication system, the method comprising:
- receiving, from a client, a request for positioning a target user device served by a mobile relay node installed in a vehicle;
- identifying a cell in which the target user device is located;
- responding to the request for positioning the target user device, by initiating a location positioning protocol procedure;
- receiving a cell identifier when the mobile relay node associates with the location services server in response to a request sent by the location services server to the mobile relay node;
- determining, 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, initiating a procedure to determine a position of a mobile relay node that operates the cell in which the target user device is located.
