Abstract
The invention discloses a method for performing switchover, which comprises the following steps that: a relay node (RN) acquires indication information of an X2 interface between base station equipment where the RN is positioned and a neighbour cell of the RN; when user equipment under the RN performs switchover, the RN judges whether the X2 interface exists between the base station equipment where the RN is positioned and the neighbour cell of the RN according to the indication information of the X2 interface, if so, the RN performs X2 switchover, otherwise the RN performs S1 switchover. The technical scheme of the embodiment of the invention has the advantage that: the RN determines how to perform the switchover according to the indication information of the X2 interface between the base station equipment where the RN is positioned and the neighbour cell of the RN when the UE performs the switchover, thereby improving the success rate of the switchover.
Description
Technical field
The present invention relates to the mobile communication technology field, particularly relate to a kind of method of initiating to switch and via node.
Background technology
Following mobile communication system, as B3G (Beyond three Generation, back three generations) system or LTE-A (Long Term Evolution Advanced, advanced long-term evolution system), to provide higher peak data rate and cell throughout, also need bigger bandwidth simultaneously.At present, the following unassigned bandwidth of 2GHz seldom, the part or all of bandwidth that the B3G system needs can only be on higher frequency range, for example 3GHz is above seeks.Frequency range is high more, and it is fast more that radio wave propagation is decayed, and transmission range is short more, under the therefore same overlay area, guarantee continuous covering, needs more base station, because the base station has higher cost usually, can increase the cost of arranging net undoubtedly.
In order to solve the cost problem of arranging net, each manufacturer and standardization body begin one's study RN (RelayNode, via node) are incorporated in the cellular system rate of increasing network coverage.As shown in Figure 1, be the network architecture schematic diagram of the LTE-A system behind the introducing RN, RN is linked into core net by the donor cell (alms giver sub-district) under the DeNB (Donor Node B, alms giver's Node B), do not have direct wave point with core net, the interface between DeNB and RN is wireless Un mouth.Each RN can control one or more sub-districts, is equivalent to an eNB, and RN and DeNB set up X2 interface, and RN is equivalent to a sub-district under the DeNB for other eNB outside the DeNB, the X2 interface between DeNB termination RN and other eNB/RN.As shown in Figure 2, be the protocol stack architecture schematic diagram of other eNB outside RN, DeNB and the DeNB, wherein, RN and DeNB all support X2-AP (AuthenticationProtocol, authentication protocol).
The inventor is in realizing process of the present invention, and there are the following problems at least to find prior art:
At present, 3GPP (3rd Generation Partnership Project, third generation partner program) do not define RN in the standard and how to know between DeNB and other eNB whether X2 interface is arranged, when the UE under the RN switched to the following sub-district of other eNB management, RN can't judge that initiating X2 switches still S1 switching.
