Abstract: When a UE has a first bearer with a gateway via a first base station and the UE engages in session setup signaling with a session server via that first bearer to set up a media session, the network may establish for the UE a second bearer via a second base station, and may the second bearer for communication of media content of the session while using the first bearer for communication control signaling for the session. In practice, the first base station could be a macro base station that operates on licensed frequency spectrum, while the second base station could be a small cell that operates on unlicensed frequency spectrum. The disclosed process can thereby help to offload communication of session content to be via the small cell instead of via the macro base station, while maintaining session control signaling to be via the macro base station.

Abstract translation: 当UE经由第一基站具有与网关的第一承载，并且UE经由该第一承载与会话服务器进行会话建立信令以建立媒体会话时，网络可以经由以下步骤为UE建立第二承载： 第二基站，并且可以使用用于会话的媒体内容的通信的第二承载，同时使用用于会话的通信控制信令的第一承载。 在实践中，第一基站可以是在许可频谱上操作的宏基站，而第二基站可以是在非许可频谱上操作的小小区。 所公开的处理可以有助于通过小型小区代替经由宏基站来卸载会话内容的通信，同时维持会话控制信令将经由宏基站。
