Embodiment Construction

[0055] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0056] In order to realize the handover of the mobile relay, the present invention provides a mobile wireless relay system, including: a mobile relay, and an eNB connected to the mobile relay, also known as a host eNB (DeNB, DonoreNB), and a DeNB is divided into a source DeNB and a target DeNB, the so-called source DeNB is the eNB connected before the mobile relay handover, and the so-called target DeNB is the eNB connected after the mobile relay handover. The target DeNB and the mobile relay constitute a relay access network, and the relay access network may also include UEs served by the mobile relay. In this system, the source DeNB is used as an intermediate node to connect the Relay access network and the EPC; when performing handover of the mobile Relay, the source DeNB forwards the data from the Relay access ne...

Abstract

The invention discloses a switching method based on a mobile relay. The method comprises that a source donor base station (DeNB) as an intermediate node connects a Relay access network and an evolved packet core (EPC) when the mobile relay is switched; the Relay access network at least comprises a target DeNB and a mobile Relay; and the source DeNB forwards the data from the Relay access network to the EPC and forwards the data from the EPC to the Relay access network. The invention further discloses a mobile radio relay system. The method and the system of the invention realize the switching of the mobile Relay so as to support the movement of Relay.

Description

technical field [0001] The invention relates to a relay technology in a cellular wireless communication system, in particular to a mobile relay-based switching method and a mobile wireless relay system. Background technique [0002] Cellular wireless communication systems such as figure 1 As shown, it is mainly composed of a user terminal (UE, User Equipment), an access network and a core network (CN, Core Network). A base station, or a network composed of a base station and a base station controller is called a radio access network (RAN, Radio Access Network), and the RAN is responsible for access layer affairs, such as management of radio resources. Physical or logical connections may exist between base stations, and each base station may be connected to one or more core network nodes. The core network is responsible for non-access stratum affairs, such as location updates, etc., and is the anchor point of the user plane. [0003] In the cellular wireless communication ...
