Problems solved by technology

[0006] Due to the wireless backhaul link connection between RN and DeNB, RN's own judgment ability and management authority, etc., the wake-up processing method of base station in LTE-A system cannot be directly applied to RN's working state adjustment

Embodiment 1

[0086] In this embodiment, the RN is deployed in a hotspot area to balance and share network loads and ensure user service performance.

[0087] In this scenario, if image 3 As shown, the specific process of RN awakening may include the following steps:

[0088] Step 301: In the scenario of this embodiment, the user density and service requirements have a certain time regularity, the OAM manager configures and pre-sets the wake-up policy in the DeNB according to the time characteristics of the user; when the time set by the wake-up policy arrives, For example, at 7 o'clock in the morning, the DeNB decides and sends the RN wake-up request (RN ACTIVATION REQUEST) to the RN to instruct the wake-up of the RN;

[0089] Step 302: After receiving the RN activation request (RN ACTIVATION REQUEST), the RN enters the working mode from the sleep mode, starts the RN cell service, and feeds back the RN wakeup confirmation message (RN ACTIVATION RESPONSE) to the DeNB.

Embodiment 2

[0091] In this embodiment, the RN is deployed on a high-speed train, and switches between corresponding eNBs as the train moves, and selects the current eNB as the DeNB of the RN, and the RN maintains the connection with the network side and the performance of the Un interface, and The R-UE is further provided with services through the DeNB.

[0092] In this scenario, since the distance between RN and DeNB changes in real time, as the train enters the station, RN connects to the eNB near the station as DeNB. For the working mode, a wake-up policy is set in advance on the DeNB that may serve as the RN. The wake-up policy may specifically be: wake up the RN when the distance between the RN and the DeNB reaches a preset distance threshold. Specifically, in this embodiment, as Figure 4 As shown, the specific process of RN awakening may include the following steps:

[0093] Step 401: When the train leaves the station, the DeNB can obtain the distance between the RN and itself in...

Embodiment 3

[0096] In this embodiment, the RN is deployed on a high-speed train, and switches between corresponding eNBs as the train moves. Provide services for R-UE.

[0097] In this scenario, since the distance between the RN and the DeNB changes in real time, as the train enters the station, the RN accesses the eNB near the station, which serves as the current DeNB of the RN, and the RN enters sleep mode after the train enters the station. However, as the parking situation of the trains in the station changes, the DeNB can decide whether to wake up all or part of the RNs to enter the working mode according to the number of RNs connected at the same time. Configure the RN number threshold on the DeNB, and configure the following wake-up strategy: when the number of currently accessed RNs is less than the pre-configured RN number threshold, wake up the RN. For example, if the preset threshold for the number of RNs is 5, then because other trains leave the station, correspondingly, the ...

Abstract

The invention discloses an RN (relay node) awaking method which comprises the following steps that: the network side judges to awake RN and sends an awaking indication to the RN according to the preset awaking strategy, or the RN judges to awake the RN self and performs self-awaking operation. The invention also discloses an RN awaking system which realizes RN awaking so that the RN and a relay cell thereof can awake the RN from a sleep mode when the RN mode needs to be adjusted according to the awaking strategy, and the RN enters a work mode to provide effective network service so as to increase the network throughput and perfect the network coverage.

Description

technical field [0001] The present invention relates to relay technology, in particular to a method and system for waking up a relay station (RN, Relay Node). Background technique [0002] Relay (Relay) technology, as an emerging technology, has attracted more and more attention, and is regarded as a key technology of B3G / 4G. Through the relay technology, the traditional single-hop link can be divided into multiple multi-hop links. Due to the shortened distance, this will greatly reduce the path loss, help to improve the transmission quality, and expand the communication range, thus providing users with more Faster and better service. [0003] Such as figure 1 As shown, in the network where RN is introduced, the link between the base station (eNB) and the macro cell user (M-UE, Macro User Equipment) is called the direct link (Direct Link), and the link between the base station and the relay station is called It is the backhaul link, also known as the Un interface. The ser...
