Abstract
A communication device for handling an open direct discovery comprises a storage unit for storing instructions and a processing means coupled to the storage unit. The processing means is configured to execute the instructions stored in the storage unit. The instructions comprise receiving a discovery update message from a first proximity service (ProSe) function, wherein the discovery update message indicates a ProSe Application Code corresponding to a discovery filter or a ProSe Application ID corresponding to the ProSe Application Code; and stopping performing an open direct discovery according to the discovery filter.
Claims20
A communication device for handling an open direct discovery, comprising:
- a storage unit for storing instructions of:
- receiving a discovery update message from a first proximity service (ProSe) function, wherein the discovery update message indicates a ProSe Application Code corresponding to a discovery filter or a ProSe Application ID corresponding to the ProSe Application Code;
- and
- stopping performing an open direct discovery according to the discovery filter;
- and
- a processing means, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
A network node for handling an open direct discovery, comprising:
- a storage unit for storing instructions of:
- transmitting an update message for updating a proximity service (ProSe) Application Code to a ProSe function, if at least one of the following operations occur:
- a reception of an announce revocation request message indicating a ProSe Application Code or a ProSe Application ID corresponding to the ProSe Application Code from an announcing user equipment (UE), a transmission of a discovery termination request message to the announcing UE, or a determination of the announcing UE being out of a coverage area of the open direct discovery when a periodic active timer expires and the announcing UE does not transmit an activity report message to the network node within a guard time interval;
- and
- a processing means, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
