<p>A method for mapping each radio bearer over Uu interface to a corresponding radio bearer over Un interface of a relay- device in a wireless communication network is provided. The method includes the steps: creating a first context for a User Equipment (UE) with original IMSI (International Mobile Subscriber Identity) of the UE at the Uu interface of the relay device, creating a second context for the UE with an allocated relay identity at the Un interface of the relay device, wherein the allocated relay identity is allocated based on the original IMSI of the UE, forming a relationship between the first context and the second context based on the relationship between the original IMSI and the allocated relay identity, and mapping the radio bearer over the Uu interface to the radio bearer over the Un interface based on the relationship between the first context including the radio bearer over the Uu interface and the second context including the radio bearer over the Un interface.</p> |
