Abstract:
1. A method for mapping each radio bearer over a Uu interface to a corresponding radio bearer over a Un interface of a relay device in a wireless communication network, including: creating a first context for a User Equipment (UE) with an original IMSI (International Mobile Subscriber Identity) of the UE at the Uu interface of the relay device, wherein the first context includes information for the radio bearer over the Uu interface; 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 has a relationship with the original IMSI, and wherein the second context includes information for the radio bearer over the Un interface; 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 and the second context.
