The discontinuous coverage network comprises at least one transfer zone (TZ1, TZ2) and at least one intermediate area (IZ), wherein data is transferred to and stored in a cache (CA1, CA2) of the mobile terminal (MT1, MT2) while the mobile terminal is in the transfer zone. The proposed method includes a transfer time extension (TTEX) comprising the steps of: detecting a filling level of the cache when the mobile terminal exits the transfer area, and continuing to fill the cache of the mobile terminal outside a transfer zone until the cache filling level reaches a predefined threshold value (TV).
