Pre-configuration of devices supporting national security and public safety communications

A method, in a wireless device configured for operation in a wireless communication network and further configured for device-to-device communication with one or more other wireless devices, the method comprising:

• receiving first and second discovery filters corresponding to a particular application and associated timing information, the associated timing information defining respective first and second validity intervals for the first and second discovery filters, such that the first and second validity intervals are at least partly non-overlapping;
• and,
• subsequent to receiving the first and second discovery filters and associated timing information, monitoring, during the first validity interval, for a discovery message that includes or is based on the first discovery filter, and monitoring, during the second validity interval, for a discovery message that includes or is based on the second discovery filter.

A wireless device, comprising a radio circuit configured for communication with a wide-area wireless network and for device-to-device communication with one or more other wireless devices and further comprising a processing circuit configured to control the radio circuit and to:

• receive from a coordinating node, using the radio circuit, first and second application codes corresponding to a particular application and associated timing information, the associated timing information defining respective first and second validity intervals for the first and second application codes, such that the first and second validity intervals are at least partly non-overlapping;
• and,
• subsequent to receiving the first and second application codes and associated timing information, control the radio circuit to transmit, during the first validity interval, one or more discovery messages that include or are based on the first application code, and to transmit, during the second validity interval, one or more discovery messages that include or are based on the second application code.

A method, in one or more network nodes adapted to provide device-to-device-related services to wireless devices operating in a wireless communication network, the method comprising:

• receiving an application code request for a particular application from a first wireless device;
• and
• sending first and second application codes for the particular application and associated timing information to the first wireless device, in response to the application code request, the associated timing information defining respective first and second validity intervals for the first and second application codes, such that the first and second validity intervals for the first and second application codes are at least partly non-overlapping.

A network node adapted to provide device-to-device-related services to wireless devices operating in a wireless communication network, the network node comprising a communication interface configured for communication with one or more wireless devices and further comprising a processing circuit configured to control the communication interface and to:

• receive an application code request for a particular application from a first wireless device;
• and
• send first and second application codes for the particular application and associated timing information to the first wireless device, in response to the application code request, the associated timing information defining respective first and second validity intervals for the first and second application codes, such that the first and second validity intervals for the first and second application codes are at least partly non-overlapping.
