transmitting additional mobile device capability information including the at least one mobile device component identifier to the network node in response to the request for the additional capability information,

wherein the at least one mobile device component identifier identifies at least one hardware or software component of the mobile device, and

wherein the at least one mobile device component identifier is indicative of capability information specifying at least one capability of the mobile device for communication with the mobile communication network.

2. The method of claim 1 , further comprising:

communicating with the network node to configure a wireless connection between the mobile device and the network node according to mobile device capability information indicated by the at least one mobile device component identifier,

wherein the at least one mobile device component identifier comprises a first subfield identifying a vendor associated with the hardware or software component of the mobile device or the mobile device itself and a second subfield identifying a particular hardware or software component of the mobile device, and

wherein the mobile device supplies the at least one mobile device component identifier to the network node during attachment to the mobile communication network.

3. The method of claim 1 , further comprising:

receiving an indication from the network node regarding a proportion of capability information indicated by the at least one mobile device component identifier to be transmitted to the network node along with the at least one mobile device component identifier; and

transmitting, to the network node, along with the at least one mobile device component identifier, one of:

no capability information indicated by the at least one mobile device component identifier,

a subset of the capability information indicated by the at least one mobile device component identifier,

capability information for carrier aggregation, CA, only for band combinations of less than a predetermined number of bands, or

all of the capability information indicated by the at least one mobile device component identifier.

4. The method of claim 1 , further comprising:

wherein an additional mobile device component identifier identifies at least one alternative hardware or software component of a mobile device, and

wherein the additional mobile device component identifier is indicative of capability information specifying at least one alternative capability of the mobile device different from that specified by the capability information indicated by a first mobile device component identifier for communication with the mobile communication network.

5. A method for operating a network node in a mobile communication network, the method comprising:

transmitting, to a mobile device, a request for capability information after initial establishment with the mobile device;

receiving, from the mobile device, mobile device capability information including a mobile device component identifier field, wherein the mobile device component identifier field indicates that the mobile device can transmit at least one mobile device component identifier;

checking a stored database of mobile device component identifiers to determine if the at least one mobile device component identifier is stored, and if so obtaining from a database capability information indicated by the at least one mobile device component identifier specifying at least one capability of the mobile device for communication with the mobile communication network;

transmitting, to the mobile device, a request for additional capability information; and

receiving, from the mobile device, additional mobile device capability information including the at least one mobile device component identifier,

wherein the at least one mobile device component identifier identifies at least one hardware or software component of the mobile device.

6. The method of claim 5 , further comprising:

transmitting mobile device capability information including the at least one mobile device component identifier to a core network node within the mobile communication network; and

configuring a network connection between the mobile device and the network node on a basis of the capability information indicated by the at least one mobile device component identifier.

7. The method of claim 5 , wherein if the stored database of mobile device component identifiers does not include a received mobile device component identifier, the method further comprises:

configuring a network connection between the mobile device and the network node on a basis of additional capability information received from the mobile device.

8. The method of claim 5 , further comprising one of:

transmitting, to another network node, the additional mobile device capability information received from the mobile device including the at least one mobile device component identifier; or

transmitting, to another network node, the additional mobile device capability information received from the mobile device, the additional mobile device capability information having been modified by a substitution of capability information obtained from a database for the at least one mobile device component identifier.

9. A mobile device in a mobile communication network, the mobile device comprising:

a transceiver; and

a controller coupled with the transceiver and configured to control to:

receive a request from a network node for capability information,

transmit mobile device capability information including a mobile device component identifier field to the network node within the mobile communication network, wherein the mobile device component identifier field indicates that the mobile device can transmit at least one mobile device component identifier,

receive from the network node a request for additional capability information, and

transmit additional mobile device capability information including the at least one mobile device component identifier to the network node in response to the request for additional capability information,

wherein the at least one mobile device component identifier identifies at least one hardware or software component of the mobile device, and

wherein the at least one mobile device component identifier is indicative of capability information specifying at least one capability of the mobile device for communication with the mobile communication network.

10. A network node in a mobile communication network, the network node comprising:

a transceiver; and

a controller coupled with the transceiver and configured to control to:

transmit a request for capability information to a mobile device after initial establishment with the mobile device,

receive from the mobile device capability information including a mobile device component identifier field, wherein the mobile device component identifier field indicates that the mobile device can transmit at least one mobile device component identifier,

check a stored database of mobile device component identifiers to determine if the at least one mobile device component identifier is stored, and if so obtaining from a database capability information indicated by the at least one mobile device component identifier specifying at least one capability of the mobile device for communication with the mobile communication network,

transmit a request for additional capability information to the mobile device, and

receive, from the mobile device, additional mobile device capability information including the at least one mobile device component identifier,

wherein the at least one mobile device component identifier identifies at least one hardware or software component of the mobile device.

11. The network node of claim 10 , wherein the network node comprises a base station.
