Abstract:
1. A method performed by a user equipment, comprising: sending to a first server host a request message that comprises geographical coordinates and that requests at least one cryptographically hashed network cell-identity, receiving from the first server host the at least one cryptographically hashed network cell-identity cryptographically hashed according to a cryptographic hash function, storing the at least one cryptographically hashed network cell-identity in a hashtable in the user equipment, obtaining a current network cell-identity associated with a network cell to which the user equipment currently is connected, generating a cryptographically hashed current network cell-identity by cryptographically hashing the current network cell-identity according to the cryptographic hash function, comparing the cryptographically hashed current network cell-identity with cryptographically hashed network cell-identities stored in the hashtable, and retrieving from the first server host content associated with the cryptographically hashed current network cell-identity if the cryptographically hashed current network cell-identity is among the cryptographically hashed network cell-identities stored in the hashtable, and storing said content in the hashtable in such a way that the content is associated in the hashtable with the cryptographically hashed current network cell identity, thereby enabling subsequent requesting of further content from the first server host or a second server host based on the content associated with the cryptographically hashed current network cell-identity.
