Abstract
A radio terminal (1) updates a preconfigured radio parameter (409, 814) stored in a memory (406, 810) coupled to the radio terminal (1). The preconfigured radio parameter (409, 814) is used by the radio terminal (1) to perform at least one of discovery and direct communication without the assistance of a Public Land Mobile Network (100). This contributes, for example, to flexible adaptation to conditions under which the ProSe communication without the assistance of a network is performed.
Claims22
A radio terminal comprising:
- at least one radio transceiver including a radio transceiver for communicating with a Public Land Mobile Network (PLMN);
- at least one processor coupled to the at least one radio transceiver;
- a protocol module including a software module to be executed by the at least one processor, the protocol module being configured to perform, using the at least one radio transceiver, at least one of PLMN-assisted discovery and PLMN-assisted direct communication within a coverage of the PLMN, the protocol module being configured to perform, using the at least one radio transceiver, at least one of non-PLMN-assisted discovery and non-PLMN-assisted direct communication according to a preconfigured radio parameter;
- and
- an updating module configured to update the preconfigured radio parameter stored in a memory coupled to the radio terminal.
A Universal Integrated Circuit Card (UICC) configured to be coupled to a radio terminal, the UICC comprising:
- a processor;
- a memory area configured to store a preconfigured radio parameter used by the radio terminal to perform at least one of non-Public Land Mobile Network (PLMN)-assisted discovery and non-PLMN-assisted direct communication;
- and
- a software module to be executed by the processor to update the preconfigured radio parameter stored in the memory area.
-30. (canceled)
A method performed in a radio terminal, the method comprising:
- updating a preconfigured radio parameter stored in a memory coupled to the radio terminal, wherein
- the preconfigured radio parameter is used by the radio terminal to perform at least one of non-Public Land Mobile Network (PLMN)-assisted discovery and non-PLMN-assisted direct communication.
