Embodiment 1

[0042] The first embodiment of the present invention provides a resource processing method based on relay device switching, such as Figure 5 As shown, the method includes the following steps:

[0043] Step 501: The RN determines whether the target DeNB needs to divide resources for the RN according to a preset strategy. Among them, when the Un interface opens the carrier aggregation function, the RN needs to determine whether the target DeNB needs to divide resources for the RN according to a preset strategy for each frequency point.

[0044] Specifically, the RN may determine whether the target DeNB is required to configure backhaul subframe information for the RN according to a preset strategy. Further, the RN determines whether the target DeNB needs to configure backhaul subframe information for the RN according to the frequency information of the target cell and the frequency information of the RN at the Uu interface.

[0045] In practical applications, when the frequency infor...

Embodiment 2

[0058] The second embodiment of the present invention provides a resource processing method based on relay device handover. This embodiment takes the X2 handover process as an example for description. Image 6 As shown, the method includes the following steps:

[0059] Step 1. RN sends a measurement report to the source DeNB.

[0060] Step 2. According to the measurement report, when the RN needs to be handed over, the source DeNB sends a handover request (Handover Request) message to the target DeNB.

[0061] Among them, if the RN communicates with the source DeNB and there is a backhaul subframe restriction on the Un port, the source DeNB can optionally send the backhaul subframe configuration information of the RN to the target DeNB in ​​the handover request message, for example, the RN The backhaul subframe configuration information is placed in the handover preparation information and sent to the target DeNB.

[0062] In practical applications, in order to reduce the impact on us...

Embodiment 3

[0080] The third embodiment of the present invention provides a resource processing method based on relay device handover. This embodiment takes the S1 handover process as an example for description. Figure 7 As shown, the method includes the following steps:

[0081] Step 1. RN sends a measurement report to the source DeNB.

[0082] Step 2. According to the measurement report, when the RN needs to handover, the source DeNB sends a handover required (Handover Required) message to the source MME.

[0083] Specifically, if there is a backhaul subframe restriction on the Un port when the RN communicates with the source DeNB, the source DeNB can optionally send the backhaul subframe configuration information of the RN to the target DeNB in ​​the handover request message, such as in Source To In the Target Transparent Container IE, the backhaul subframe configuration information of the RN is sent to the target DeNB.

[0084] Step 3. The source MME finds the target MME and sends a forward ...

Abstract

The invention discloses a resource processing method and equipment based on relay node (RN) handover. The method comprises the following steps: an RN judges whether a donor evolved node B (DeNB) is needed for dividing resources for the RN according to a preset strategy; and the RN informs the DeNB of the judgment result. The embodiment of the invention has the advantages that sub-frame configuration of a backhaul link can be completed during the handover process, configuration of a carrier aggregation (CA) cell is coordinated, influence on RN operation is reduced, business continuity of a user is ensured maximally, and the number of lost packets is reduced so as to provide good network experiences for the user.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a resource processing method and equipment based on relay device switching. Background technique [0002] In future mobile communication systems, such as B3G (Beyond Third Generation) or LTE-A (Long Term Evolution-Advanced), the system will provide higher peak data rates and cell throughput, and also More bandwidth is needed. Currently, there are few unallocated bandwidths below 2GHz. Part or all of the bandwidth required by the B3G / LTE-A system can only be found in higher frequency bands (for example, above 3GHz). Among them, the higher the frequency band, the faster the radio wave propagation attenuation, and the shorter the transmission distance. In the same coverage area, to ensure continuous coverage, more base stations are needed. However, because base stations have higher costs, they will increase the cost of network deployment. Networking cost and coverage ...
