Mobile radio communication system
View Patent ↗A mobile radio communication system having a mobile radio communication network and a mobile radio subscriber appliance, wherein a unit in the network layer of the core network of the mobile radio communication network is configured to transmit to the mobile radio subscriber appliance a first message, based on an occurrence of a predetermined event, with a request for a statement which describes at least one radio characteristic of the mobile radio subscriber appliance.
1. An apparatus, comprising:
a mobile radio subscriber appliance configured to:
receive a first message including a request for a statement that describes at least one radio characteristic of the mobile radio subscriber appliance, the first message triggered by registration of the mobile radio subscriber appliance in a mobile radio communication network and being sent by a unit in a network layer of a core network; and
transmit a second message with a statement that describes the at least one radio characteristic of the mobile radio subscriber appliance.
2. The apparatus as claimed in claim 1 , wherein the first message is triggered by activation of the mobile radio subscriber appliance at a Serving GPRS Support Node (SGSN) associated with a core network of a mobile radio communication network.
3. The apparatus as claimed in claim 1 , wherein the request is included in an Attach Accept message.
4. The apparatus as claimed in claim 1 , wherein the statement is included in an Attach Complete message.
5. A method, comprising:
receiving, at a mobile radio subscriber appliance, a first message with a request for a statement which describes at least one radio characteristic of the mobile radio subscriber appliance, the first message triggered by registration of the mobile radio subscriber appliance in a mobile radio communication network and sent by a unit in a network layer of a core network; and
transmitting, by the mobile radio subscriber appliance, a statement which describes the at least one radio characteristic of the mobile radio subscriber appliance.
6. The method as claimed in claim 5 , wherein the first message is triggered by activation of the mobile radio subscriber appliance at a Serving GPRS Support Node (SGSN) associated with a core network of a mobile radio communication network.
7. The method as claimed in claim 5 , wherein the request is included in an Attach Accept message.
8. The method as claimed in claim 5 , wherein the statement is included in an Attach Complete message.
9. An apparatus, comprising:
core network network-layer unit configured to:
transmit a first message, based on an occurrence of a predetermined event, including a request for a statement that describes at least one radio characteristic; and
receive a second message, sent by a mobile radio subscriber appliance, including a statement that describes the at least one radio characteristic of the mobile radio subscriber appliance; and
an additional core network network-layer unit, wherein the core network network-layer unit is further configured to transmit to the additional core network network-layer unit the statement which describes the at least one radio characteristic of the mobile radio subscriber appliance upon an inter-system handover of the mobile radio subscriber appliance.
10. The apparatus as claimed in claim 9 , wherein the core network network-layer unit is further configured to transmit to a further unit in a network-layer of a further core network the statement that describes the at least one radio characteristic of the mobile radio subscriber appliance upon an inter-system handover of the mobile radio subscriber appliance.
11. The apparatus as claimed in claim 9 , wherein the predetermined event is a registration of the mobile radio subscriber appliance in a core network.
12. The apparatus as claimed in claim 9 , wherein the core network network-layer is further configured to store the statement which describes the at least one radio characteristic of the mobile radio subscriber appliance.
