Title
(EN) DEVICE TO DEVICE DISCOVERY VIA A RELAY DEVICE
(FR) DÉCOUVERTE DE DISPOSITIF À DISPOSITIF PAR L'INTERMÉDIAIRE D'UN DISPOSITIF RELAIS
Abstract
(EN)
Mobile device-to-mobile device discovery may be performed via a relay device (e.g., wireless transmit and receive unit (WTRU)), which may send a discovery request (e.g., including service ID, relay capability indication, and relay WTRU ID) to a ProSe server. A discovery response may include a (e.g., ProSe) relay service broadcast code and discovery filter (e.g., corresponding to service ID for a service broadcast by a service provider WTRU). The relay WTRU may use the discovery filter to listen for a ProSe code broadcast by a service provider WTRU. The relay WTRU may determine a received ProSe code matches the discovery filter. The relay WTRU may broadcast the relay service broadcast code based on the match. The service broadcast code broadcast may be intended for receipt by a service utilizing WTRU, which may utilize the relay WTRU to join/receive a service from a service provider WTRU.
(FR)
La découverte de dispositif mobile à dispositif mobile peut être effectuée par l'intermédiaire d'un dispositif relais (par exemple, une unité d'émission et de réception sans fil (WTRU)), qui peut envoyer une demande de découverte (par exemple, comprenant un identifiant de service, une indication de capacité de relais, et un identifiant de WTRU de relais) à un serveur ProSe. Une réponse de découverte peut comprendre un code de diffusion de service de relais (par exemple, ProSe) et un filtre de découverte (par exemple, correspondant à un identifiant de service pour un service diffusé par une WTRU de fournisseur de services). La WTRU de relais peut utiliser le filtre de découverte pour écouter un code ProSe diffusé par une WTRU de fournisseur de services. La WTRU de relais peut déterminer un code ProSe reçu correspondant au filtre de découverte. La WTRU de relais peut diffuser le code de diffusion de service de relais sur la base de la correspondance. La diffusion de code de diffusion de service peut être destinée à être reçue par un service utilisant une WTRU, qui peut utiliser la WTRU de relais pour rejoindre/recevoir un service provenant d'une WTRU de fournisseur de services.
