Problems solved by technology

[0006] First, customers may face high roaming charges
Customers may be reluctant to accept such roaming charges only for the purpose of D2D communication
Second, there may be an uncontrolled load on operators that are roaming destinations—that is, operators whose resources may be used by roaming D2D devices
Therefore, these methods may not be compliant with 3GPP TS 22.278

Embodiment Construction

[0028] Certain embodiments may relate to Proximity Services (ProSe) / Device-to-Device (D2D) discovery and communication. More specifically, certain embodiments address how a user equipment (UE) can be served by different operators and still perform D2D discovery and communication.

[0029] In some embodiments, a network (NW) element may broadcast radio resource information related to different operators, such as the operator's public land mobile network (PLMN) identifier (id) and the operator's support for inter-operator D2D operation frequency band / carrier. Not every operator will support inter-operator D2D operations. Therefore, such information may be helpful in inter-operator D2D discovery and communication.

[0030] In some embodiments, there may be two types of discovery messages that can be selected by the UE in the discovery signal. One type of discovery message can contain certain information for intra-operator and inter-operator D2D or other scenarios where applica...

Abstract

Various communication systems may benefit from inter-operator device-to-device operation. For example,communication systems of the third generation partnership project (3GPP) long term evolution (LTE) advanced (LTE-A) release12 / 13 (Rel-12 / 13) or future releases may use such operation with respect to D2D communications. A method can include preparing, at a network element operated by an operator, radio resource information related to one or more operators other than the operator. The method can also include broadcasting, by the network element, the radio resource information. The radio resource information can be configured to permit a user equipment served by the network element to perform device-to-device discovery and / or communication with another user equipment served by at least one of the one or more operators.

Description

technical field [0001] Various communication systems can benefit from inter-carrier device-to-device operations. For example, a communication system of 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) Advanced (LTE-A) Release 12 / 13 (Rel-12 / 13) or future releases may use such operations on D2D communication. Background technique [0002] A shared carrier frequency between transmitter and receiver can be a prerequisite for a communication link. In the case of inter-operator device-to-device (D2D) communication, according to conventional deployment methods, the transmitter and receiver are user equipments (UEs) served by different operators with different carriers and / or frequency bands. [0003] For UEs served by different operators with different carriers and / or frequency bands, there are several ways to establish a D2D link on the same carrier / frequency band. Such a manner of supporting D2D link establishment will be useful for supporting D2D operations ...
