[0021] Assume that the ARP priority of the RN E-RAB of the first service accepted is higher (set to 5), and the UE E-RAB of the second service being served by the target cell is lowered because of the lower ARP priority (set to 10) Released by the target DeNB; at the same time, the ARP priority of the UE EPS bearer mapped to the third service carried by the RN EPS is lower (set to 12), and will also be served by the target cell, which is equivalent to ARP priority The resources of the UE EPS bearer with ARP priority 10 are preempted by the UE EPS bearer with ARP priority 12, which causes the second service carried by the UE EPS bearer with ARP priority 10 to be unnecessarily suspended, thus damaging the target cell Quality of service of the serving UE
[0022] Assume that a certain RN E-RAB refuses to accept the RN E-RAB because the ARP priority is low (set to 10), and the ARP priority of the UE E-RAB being served by the target cell is greater than 10 (for example, There are values ​​between 1 and 9) so that it

Example Embodiment

[0063] The basic idea of ​​the handover control method in the relay system proposed by the present invention is that the source donor base station (S-DeNB) notifies the QoS parameters of the UE E-RAB mapped to the RN E-RAB (directly or via the RN MME and / or the forwarding of the target RN MME to notify) the target host base station (T-DeNB); T-DeNB determines whether to accept the RN EPS bearer according to the QoS parameters, which can be divided into three cases: fully accept the RN EPS bearer; partially accept RN EPS bearer; reject RN EPS bearer. For the case of partial admission, T-DeNB may send (directly or through forwarding by RN MME and / or target RNMME) acceptable QoS parameters for partially accepted RN EPS bearers to S-DeNB. For partial acceptance, T-DeNB can also send RN DRB reconfiguration information (directly or via RN MME and / or target RN MME forwarding) to S-DeNB, and then S-DeNB reconfigures RN DRB The information is notified to the RN. The RN releases the ...

Abstract

The invention provides a switching control method of a relay system. The switching control method of the relay system comprises the following steps: A, notifying quality of service (QoS) parameter which is mapped to an user experience (UE) E-radio access bearer (RAB) of an user device on the E-RMB of a retrieval number (RN)-universal terrestrial radio access network (UTRAN) of the relay node to a target host base station T-DeNB by a source host base station S-DeNB; B, ensuring whether the T-DeNB accept the even parity select ( EPS) bearing of a RN evolvement grouping system according to the Qos parameter. Three specific conditions are as follows: accepting the EPS bearing of the RN completely; accepting the EPS bearing of the RN partially; and rejecting the EPS bearing of the RN.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a switching control method in a relay system. Background technique [0002] In the LTE / LTE-A mobile communication system, the X2 interface handover control process for the UE in the prior art is as follows: figure 1 shown, including the following steps: [0003] Step 101: a source base station (eNB) sends a handover request (Handover Request) message to a target eNB, and the message includes a target cell identifier and UE context information. Among them, the UE context information includes the UE Evolved Universal Terrestrial Radio Access Network (E-UTRAN) radio access bearer (E-RAB, E-UTRAN Radio Access Bearer) list requested to be established, and the radio resource control (RRC, Radio Resource Control) context. [0004] In the UE E-RAB list requesting establishment, for each UE E-RAB requesting establishment, the UE E-RAB identifier and UE E-RAB-leve...
