Example Embodiment

[0085] Example one

[0086] In this embodiment, RNs are deployed in hotspots to balance and share network loads and ensure user service performance.

[0087] In this scenario, such as image 3 As shown, the specific process of waking up the RN may include the following steps:

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

Example Embodiment

[0090] Example two

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

[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 the DeNB. After the train enters the station, the RN can enter the sleep mode, and the RN needs to switch after the train leaves the station. In the working mode, a wake-up strategy is set in advance on the DeNB that may be the RN. The wake-up strategy 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 waking up the RN may include the...

Example Embodiment

[0095] Example three

[0096] In this embodiment, the RN is deployed on a high-speed train, and as the train moves, it switches between the corresponding eNBs. The RN maintains the connection with the network side and the Un interface performance, and further passes through the eNB as its own DeNB. 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. The eNB serves as the current DeNB of the RN. After the train enters the station, the RN enters a sleep mode. However, as the situation of the trains in the station changes, the DeNB can decide whether to wake up all or part of the RNs and enter the working mode according to the number of RNs that are connected at the same time. The RN number threshold is configured on the DeNB, and the following wake-up strategy is configured: when the number of currently connected RNs is less than the pre-c...

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...
