Abstract

An apparatus of a node of a network comprises one or more baseband processors to process a first user equipment (UE) capability report from a first UE, and to process a second UE capability report from a second UE, wherein the first UE capability report and the second UE capability report include a same UE capability ID for the first UE and the second UE, and wherein the first capability report includes partial UE capability information for the first UE and the second capability report includes partial UE capability information for the second UE. The apparatus can include a memory to store the first capability report and the second capability report.

First claim

What is claimed is:

1. An apparatus of a node of an access network, comprising:
radio frequency circuitry configured to communicate with a first user equipment (UE) and a second UE; and
one or more baseband processors communicatively coupled to the radio frequency circuitry and configured to perform operations comprising:
processing a first UE capability report from the first UE;
processing a second UE capability report from the second UE, wherein the first UE capability report and the second UE capability report include a same UE capability ID for the first UE and the second UE;
sending the UE capability ID to a core network node; receiving a first request from the core network node to retrieve capabilities from at least one of the first UE and the second UE;
sending, to at least one of the first UE and the second UE, a second request to provide the respective UE capabilities using a band filter associated with a public land mobile network (PLMN);
receiving, from at least one of the first UE and the second UE, a respective further UE capability report including a partial UE capability information compiled using the band filter associated with the PLMN and a partial tag added by the one or more baseband processors; and
tagging each respective further UE capability report with one of multiple geographical areas within the PLMN from which the respective further UE capability information was retrieved.

2. The apparatus of claim 1 , wherein
each respective further UE capability report comprises the UE capability report ID and partial UE capability information compiled using the band filter associated with the PLMN.

3. The apparatus of claim 2 , wherein each respective further UE capability report comprises a group of common parameters and a group of disjoint parameters, wherein the common parameters are compared, and the disjoint parameters are merged to create combined UE capabilities information.

4. The apparatus of claim 2 , wherein the respective further UE capability reports include an indication of any filter applied when encoding the UE capability information.

5. The apparatus of claim 1 , wherein the one or more baseband processors are to add a partial tag to each respective further UE capability report.

6. A node of a core network configured to perform operations, comprising:
processing a first user equipment (UE) capability report from a first UE;

processing a second UE capability report from a second UE, wherein the first UE capability report and the second UE capability report include a same UE capability ID for the first UE and the second UE;
determining the core network does not have a record of the UE capability ID;
sending, to an access network, a request to retrieve capabilities from the first UE and second UE using a band filter associated with a public land mobile network (PLMN) in response to determining the core network does not have a record of the UE capability ID;
processing a first further UE capability report including a partial UE capability information compiled using the band filter associated with the PLMN and a partial tag added by one or more baseband processors of an apparatus of a node of the access network from the first UE;
processing a second further UE capability report including a partial UE capability information compiled using the band filter associated with the PLMN and a partial tag added by the one or more baseband processors of the apparatus of the node of the access network from the second UE;
tagging each of the further UE capability report with one of multiple geographical areas within the PLMN from which the respective further UE capability information was retrieved; and
storing the each further UE capability in a database.

7. The node of claim 6 , wherein
each further UE capability report comprises a group of common parameters and a group of disjoint parameters, wherein the UE capability ID reports include a partial tag indicating the reports include partial UE capability information.

8. The node of claim 7 , wherein the common parameters are compared, and the disjoint parameters are merged to create combined UE capabilities information.

9. The node of claim 6 , wherein validation of the UE capability information per geographical area is performed separately.

10. The node of claim 7 , wherein the respective further UE capability reports include an indication of any filter applied when encoding the UE capability information.

11. The node of claim 6 , the operations further comprising:
adding a partial tag to each further UE capability report.

12. The apparatus of claim 1 , further comprising:
sending, after tagging each respective further UE capability report with one of multiple geographical areas within the PLMN, the respective further UE capability reports to the core network node.

13. The apparatus of the claim 1 , wherein the core network node is an access mobility management function (AMF) of the core network.

14. The apparatus of claim 1 , wherein the band filter associated with the PLMN is provided by a network operations and maintenance center.

15. The node of claim 6 , wherein tagging each further UE capability report with one of multiple geographical areas within the PLMN from which the respective further UE capability information was retrieved is based on a base station from which the further UE capability report was received.
