Description

Host relay device resident processing method and device

Technical field

The present invention relates to communication technologies, and in particular, to a method and a device for residing a UE relay device. Background technique

With the widespread use of third-generation mobile communication technologies (3rd-generation, 3G) and smart terminals, the demand for communication is centering on traditional small data services (such as voice, data services, etc.) and multimedia. For the central transformation, such as image, streaming media, cloud service business, etc., these emerging business needs need to further improve the network capacity and user service experience. In response to the rapid growth of mobile data service traffic, operators have proposed a scenario of small cell/small eNB deployment, that is, where users (User Equipment, UE for short) are used, such as supermarkets and shopping malls. In other places, densely deploying small cells with small coverage to support the huge services generated in the area enables more UEs to enjoy wider bandwidth and higher-speed data services. The access nodes of the small cell may be Low Power Node (LPN), Femtocell, Picocell, Wireless Fidelity (WI-FI) Access Point (Access). Point, referred to as AP).

As the access nodes of small cells are densely deployed in hotspots, traditional backhaul solutions will face enormous challenges. Specifically, the backhaul mainly refers to a path in which the access node of the small cell transmits data to the base station (eNB). In the prior art, the fiber backhaul and the microwave backhaul are mainly used. However, since the access nodes of the small cell are densely deployed in the hotspot area, That is, it may be mainly deployed in hotspots such as utility poles and outside buildings, and the number of deployments is huge, which increases deployment and maintenance costs. In particular, the way of wired backhaul such as fiber backhaul is greatly limited in deployment. In addition, the signal coverage area of the small cell is much smaller than that of the macro cell, so the number of UEs in the small cell coverage is small, and the UE mobility effect is enhanced, resulting in frequent and obvious backhaul fluctuations. In response to these problems, the prior art proposes to use the UE to provide wireless backhaul transmission for the macro cell and the small cell, and the UE cost is low.

However, in the prior art, the UE can only camp on one cell, and does not notify the camped cell after camping, which results in a large link delay when using the UE to provide wireless backhaul transmission, so When the line backhaul capacity is limited, it cannot respond quickly.

FIG. 7 is a schematic structural diagram of Embodiment 4 of a UE relay device according to the present invention. The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. The embodiments are a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In the embodiment of the present invention, a UE relaying device is used as a relay to support a wireless backhaul of a macro eNB and a small eNB. In this manner, the UE relay device needs to be stationed at the same time. Stay in two cells, which can better improve the capacity of the wireless backhaul. In the way of implementing this wireless backhaul, traditional backhaul can exist at the same time.

FIG. 1 is a schematic flowchart of Embodiment 1 of a method for processing a UE relay device according to the present invention. As shown in FIG. 1, the method includes:

5101. The UE relay device determines to camp in the first cell. Specifically, the UE relay device determines whether to camp in the first cell according to the measured first cell received signal quality value.

5102. The UE relay device measures a second cell receiving signal quality value of the second cell supporting the UE relay device. After the UE relay device resides in the first cell, the second cell suitable for camping is further selected, which is determined by measuring the received signal quality value of the second cell of the second cell.

The UE relay device determines to stay in the second cell according to the received signal quality value of the second cell, or the UE relay device receives the signal quality value according to the first cell of the first cell, and receives the second cell. The signal quality value is determined to reside in the second cell described above.

In general, it may be determined whether to camp on the second cell based only on the received signal quality value of the second cell. Preferably, since the UE relay device is to camp on the first cell and the second cell at the same time, after the UE relay device resides in the first cell, the second cell that is camped on can be simultaneously combined with the first cell to receive. The signal quality value and the second cell received signal quality value are determined.

5104. The UE relay device notifies the first cell and the second cell of the camping result of the UE relay device.

In this embodiment, after the UE relay device determines to camp on the first cell, it further determines the second cell that camps to complete the simultaneous camping on the two cells, and notifies the resident result to the resident. The first cell and the second cell, so that in a subsequent communication process, if the traditional backhaul of the first cell and the second cell is limited, the first cell or the second cell may camp from the first cell and the second cell simultaneously One or more UE relay devices are activated in the UE relay device list as the transmission support of the wireless backhaul, which improves the wireless backhaul capacity and solves the problem of limited backhaul.

After the UE relay device determines to camp in the second cell, it also notifies the first cell and the second cell of the camping result, and the UE relay device notifies the first cell and the second cell of the camping result. Two ways:

In one mode, the UE relaying device sends the first camping result message to the first cell, where the first camping result message includes: the UE relay device identifier and the second cell identifier. Then, the first cell sends a second camp result message carrying the UE relay device identifier to the second cell.

Another way is that the UE relay device sends the first camp result message to the first cell, and The second camping result message is sent to the second cell, where the first camping message includes the UE relaying device identifier and the second cell identifier; and the second camping result message includes: the UE relaying device identifier.

Thus, when the backhaul is limited, the first cell and the second cell know which UE relay devices are camping therein, and then the first cell or the second cell can activate the camped UE to support the wireless backhaul.

In the specific implementation process, before the UE relay device determines to camp in the first cell, the method further includes: the UE relay device receiving broadcast information of any cell; and the UE relay device determining whether the broadcast information carries the UE in the foregoing support Following the second cell list of the device, if yes, the cell is used as the first cell, and the broadcast information is used as the first broadcast information, and the list of the second cell supporting the UE relay device is parsed from the first broadcast information. Otherwise, the broadcast information is discarded and there is no need for further analysis. It should be noted that the foregoing list may be carried in an information element (Information Element, IE for short) of the broadcast information. In addition, after the foregoing cell is used as the first cell, the UE relay device measures the received signal quality of the first cell of the first cell, and determines to camp on the first cell according to the quality of the first cell received signal.

2 is a schematic flowchart of Embodiment 2 of a method for camping a UE relay device according to the present invention, where the first cell is an eNB, and the second cell is a relay node (Relay Node, RN for short), and the foregoing method Includes:

S201: The UE relay device receives first broadcast information of any eNB.

5202. The UE relay device determines whether the first broadcast information carries a RN list supporting the UE relay device, and if yes, performs S203, otherwise discards the broadcast information.

S203. The UE relay device parses the RN list that supports the UE relay device.

S204. The UE relay device measures a first received signal quality value of the eNB, and determines to camp on the eNB side according to the first received signal quality value. When the first received signal quality value satisfies the preset condition, the UE relay device camps on the eNB side. It should be noted that the eNB is an eNB that transmits the first broadcast information.

S205. The UE relay device measures a second received signal quality value of the RN.

S206. The UE relay device determines to reside on the RN side according to the second received signal quality value. It should be noted that S206 may be replaced by the UE relay device determining to camp on the RN side according to the first signal receiving quality and the second received signal quality.

5207. The UE relay device notifies the eNB to camp on the result. The resident result includes a UE relay device identifier (ID) and an RN ID. S208. The eNB notifies the RN to camp on the result. The UE relay device ID is included in the camp result. Of course, S208 can also be replaced with the UE relay device notifying the RN camping result, and the camping result includes the UE relay device ID, so that the execution of S207 and S208 can be performed in any order.

Further, before the UE relay device determines that the UE is in the first cell, the UE relay device may obtain the first cell supporting the UE relay device by using Operations Management and Management (OAM). List. Specifically, the foregoing list of the first cell is obtained by a mechanism that acquires an eNB list that supports the RN function, and the RN first initiates an attach to any eNB in the identity of the normal UE, and then adopts an OAM mode. Get the list.

Correspondingly, the UE relay device may obtain a second cell list supporting the UE relay device by using an OAM manner.

In addition, before the UE relay device determines to camp in the first cell, the UE relay device may determine a target first cell according to the current geographic location information, where the target first cell supports the UE relay device. The UE relay device may also determine the target second cell according to the current geographic location information, and the target second cell supports the UE relay device.

Specifically, the UE relay device may be configured by the high-level device to create and maintain a second cell list supporting the UE relay device according to the historical camping information, where the list includes geographic location coordinate information of each second cell, and physical The information of the cell identifier (Physical Cell Identity, PCI for short), the cell frequency point, etc., the UE relay device can determine the target that can be camped by comparing the current geographic location with the geographic location information of each second cell in the list. Second cell. Specifically, the second cell with the geographic location and the current geographic location of the UE relay device being less than a certain range is used as the target second cell. Further, the UE relay device acquires the second broadcast information of the target second cell, and the UE relay device reads the second determination parameter from the second broadcast information. The first cell is similar, and will not be described here.

The manner of obtaining the first cell list and the second cell list in the foregoing embodiment may be used in combination, which is not limited in this embodiment. For example, when there is no historical camping information, the first cell list and the second cell list supporting the foregoing UE relay device may be obtained by using the OAM method, and then the target first cell and the target second cell are determined according to the current geographic location information. If the high-layer device creates and maintains the first cell list and the second cell list according to the historical residency information, the OAM acquisition is no longer needed, and the target first cell and target can be directly determined according to the current geographic location information. Second cell.

3 is a schematic flowchart of Embodiment 3 of a method for camping a UE relay device according to the present invention, where the first cell is an eNB, and the second cell is a relay node (RN). Includes:

5302. The UE relay device determines the target eNB according to the current geographic location.

S303. The UE relay device measures a first received signal quality value of the target eNB.

5304. The UE relay device determines to reside on the target eNB side according to the first received signal quality value. When the first received signal quality value satisfies a preset condition, the UE relay device camps on the eNB.

S305. The UE relay device determines the target RN according to the current geographic location information. In this embodiment, it is assumed that the high-level device has created and maintained an RN list according to the historical residency information, and the RNs in the list support the UE relay device.

S306. The UE relay device measures a second received signal quality value of the target RN.

5307. The UE relay device determines to reside on the target RN side according to the second received signal quality. It should be noted that S307 may be replaced by the UE relay device determining to camp on the target RN side according to the first signal receiving quality and the second received signal quality.

5308. The UE relay device notifies the target eNB to camp on the result. The resident result includes a UE relay device identifier (Identity, referred to as ID) and an RN ID of the target RN.

5309. The eNB notifies the target RN to camp on the result. The host result includes the UE relay device ID.

Of course, S309 can also be replaced by the UE relay device notifying the RN camping result, where the camp result includes the UE relay device ID, so that the execution of S308 and S309 can be performed in any order.

Further, the UE relay device determines to camp in the second cell according to the second cell received signal quality value, specifically: if the second cell signal quality value is greater than the second cell received signal quality threshold, The UE relay device resides in the second cell described above. Similarly, when the first cell signal quality is greater than the first cell received signal quality threshold, the first cell is determined to reside in the first cell.

It should be noted that the foregoing second cell received signal quality threshold may be sent from the second cell. Obtained in the broadcast information.

In another mode, the UE relay device determines to stay in the second cell according to the first cell received signal quality value and the second cell received signal quality value, where: the first cell received signal quality value is greater than The first cell receives the signal quality threshold, and the second cell received signal quality value is greater than the second cell received signal quality threshold, and is determined to reside in the second cell according to the preset criterion.

The foregoing preset rules may be in various manners, and are not limited in the embodiments of the present invention. For example, the foregoing determining, by using the preset criterion, that the second cell is in the second cell may determine that the absolute value of the difference between the received signal quality value of the first cell and the received signal quality value of the second cell is less than or equal to the first absolute threshold. The UE relay device resides in the second cell. The first absolute threshold may include: a first RSRP absolute threshold, a first RSRQ absolute threshold.

Further, based on the foregoing embodiment, the first received signal quality value includes: a first reference signal received power (Reference Signal Receiving Power, RSRP for short) value (denoted as WR) and a first reference signal received quality ( The Reference Signal Received Quality (RSRQ) value (denoted as WRQ), or the first received signal quality value includes: the first i. Correspondingly, the first cell receiving signal quality threshold includes: a first RSRP threshold and a first RSRQ threshold, or the first cell received signal quality threshold includes: a first RSRP threshold.

In addition, the foregoing second cell received signal quality value includes: a second RSRP value (denoted as an RSJU and a second RSRQ value (denoted as RSRQ ₂ ); or, the foregoing second cell received signal quality includes: a second RSRP value.

It should be noted that the foregoing RSRP threshold and RSRQ threshold may be obtained from broadcast information of the corresponding cell. There are no restrictions here.

Generally, RSRP and RSRQ can be obtained when measuring the cell signal reception quality value, and specifically, the relevant parameters can be measured, and then RSRP and RSRQ are calculated. In some scenarios, the RSRQ threshold is sometimes not obtained. If the RSRQ threshold is not obtained, only RSRP is used to determine whether to camp.

Correspondingly, the second cell received signal quality value is greater than the second cell received signal quality threshold, and may be specifically: the second RSRP is greater than the second RSRP threshold, and the second RSRQ is greater than the second Two RSRQ thresholds. In the case that the RSRQ threshold is not obtained, it is determined only according to the RSRP, that is, the received signal quality value of the second cell is greater than the received signal quality threshold of the second cell, and may be specifically: the second RSRP is greater than the second RSRP threshold.

Correspondingly, the UE relay device determines to reside in the second cell according to the first cell received signal quality value and the second cell received signal quality value, where: if the ^^^^ _{2 is} greater than the second RSRP threshold, And ^^^2 _{2 is} greater than the second RSRQ threshold, and then the UE relay device further determines to camp in the second cell according to the preset criterion.

For example, the UE relay device determines to reside in the second cell according to a preset criterion, and may be: ^^ and ^? The absolute value of the difference of ^/^ (denoted as | WR _ RSRP ₂ | ) is less than or equal to the first RSRP absolute threshold, ^? Whether the absolute value of the difference between ^^ and ^^^ (denoted as l WR - WR^ ) is less than or equal to the first RSRQ absolute threshold.
