Procedure for Selecting Network Discovery Method

An apparatus comprising:

• at least one processor;
• and
• at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
• perform initial channel assessment of a radio channel at maximum a determined time period shorter than or equal to the shortest of a plurality of discovery frame broadcast periodicities employed by access nodes the apparatus is configured to search for in network discovery;
• upon determining that a transmission has been detected in the initial channel assessment, select a network discovery according to a first network discovery method;
• and
• upon detecting no transmission on the radio channel during the initial channel assessment, select network discovery according to a second network discovery method different from the first network discovery method.

A computer program product embodied on a non-transitory distribution medium readable by an apparatus and comprising program instructions which, when loaded into the apparatus, execute a computer process comprising:

• performing, by the apparatus, initial channel assessment of a radio channel at maximum a determined time period shorter than or equal to the shortest of a plurality of discovery frame broadcast periodicities employed by access nodes the apparatus is configured to search for in network discovery;
• upon determining that a transmission has been detected in the initial channel assessment, selecting in the apparatus a network discovery according to a first network discovery method;
• and
• upon detecting no transmission on the radio channel during the initial channel assessment, selecting in the apparatus network discovery according to a second network discovery method different from the first network discovery method.
