Methods and Arrangements in a Cellular Network
First Claim
1. A method performed by a network node operating in a cellular network, the method comprising:
- maintaining a user equipment (UE) capability database for UEs in the cellular network that are supported by the network node and interested in forming ad hoc networks, said UE capability database comprising, for each UE represented in the database, stored information at least comprising capability information indicating capabilities of the UE with regard to radio communication;
running a matching algorithm on the UE capability database, said matching algorithm operating on the stored information for respective ones of the UEs, to determine a level of compatibility between respective ones of the UEs for ad hoc networking and thereby identify compatible UEs; and
sending a paging message for receipt by the compatible UEs, said paging message identifying the compatible UEs and thereby enabling the compatible UEs to initiate ad hoc networking with respect to one another.

Abstract
A node in a cellular network node supports ad hoc networking between UEs. The network node accesses a user equipment capability database and receives update messages from user equipments (UEs) comprising information regarding the capabilities of the UEs, such as supported frequency bands, radio access technologies, and antenna modes. The network node updates the user equipment capability database with the information from the received messages, and it uses the user equipment capability database and a matching algorithm to identify given UEs that have matching capabilities and are able to communicate wirelessly. The network node then transmits an ad hoc “paging” message identifying the UEs. The paging message is received by the identified UEs and they may then establish an ad hoc network.

8. A network node configured for operation in a cellular network and comprising:
-
communication circuitry; and processing circuitry configured to; maintain a user equipment (UE) capability database for UEs in the cellular network that are supported by the network node and interested in forming ad hoc networks, said UE capability database comprising, for each UE represented in the database, stored information at least comprising capability information indicating capabilities of the UE with regard to radio communication; run a matching algorithm on the UE capability database, said matching algorithm operating on the stored information for respective ones of the UEs, to determine a level of compatibility between respective ones of the UEs for ad hoc networking and thereby identify compatible UEs; and send, via said communication circuitry, a paging message for receipt by the compatible UEs, said paging message identifying the compatible UEs and thereby enabling the compatible UEs to initiate ad hoc networking with respect to one another. - View Dependent Claims (9, 10, 11, 12, 13, 14)
