Abstract
Information related to a set of networks from a first node to a second node of a communication system can be distributed. A set of identifiers which belong to the set of networks can be stored at the first node. Hash values are generated at the first node for the identifiers in the set of identifiers using a hash function. The generated hash values are transmitted from the first node to the second node. The second node determines an identifier of a particular network available for communicating with the second node. The second node generates a hash value for the identifier using the hash function. The second node compares the hash value of the identifier with the hash values received at the second node from the first node to determine whether the particular network belongs to said set of networks.
