In a mobile communication network, data traffic is mapped to a non-guaranteed bit rate bearer (50, 60) established between a gateway node (100) and a mobile terminal (200). The non-guaranteed bit rate bearer comprises a first sub-bearer (51, 61) between the mobile terminal (200) and an access node (120), a second sub-bearer (52, 62) between the access node (120) and an intermediate gateway node (110), and a third sub-bearer (53, 63) between the intermediate gateway node (110) and the gateway node (100). Releasing of the third sub-bearer (53, 63) is controlled on the basis of the first sub-bearer (51, 61) and/or the second sub-bearer (52, 62) being released. |
