1. A method of radio bearer transmission in dual connectivity for a network in a long term evolution (LTE) system, the method comprising:
determining a radio bearer (RB) type from among three RB types, for transmitting an RB to a mobile device according to an access point (AP) failure report received from the mobile device and at least one of an AP discovery report and assisting information received from the AP, wherein the AP discovery report includes a SSID and a BSSID of the AP selected by the mobile device, a MAC address of the mobile device, a signal quality corresponding to the selected AP and a mobile device class, and the assisting information includes SSID, BSSID, load and throughput, wherein an AP failure report configuration transmitted from the network to the mobile device for gathering information of usage of AP resource includes throughput, a number of attempts to connect with an AP, and a timer of attempts to connect with the AP, wherein the three RB types include a split RB which is transmitted by resources of both the network and the AP, an assisted RB which is transmitted by a resource of the AP, and a normal RB which is transmitted by a resource of the network;
according to the determined RB type, generating at least one packet data convergence protocol protocol data unit (PDCP PDU) by a PDCP entity of a plurality of PDCP entities of the network corresponding to the RB;
assigning the at least one PDCP PDU to be transmitted to the AP with an identity, wherein the identity indicates which PDCP entity of the network the at least one PDCP PDU belongs to, and the identity is a PDCP entity identity; and
transmitting the at least one PDCP PDU with the identity to the AP.
