Description

Method and device for camping on UE relay device

technical field

The present invention relates to communication technologies, and in particular, to a method and device for camping on a UE relay device.

Background technique

With the widespread popularization of the third-generation mobile communication technology (3rd-generation, 3G for short) and intelligent terminals, people's demand for communication is shifting from traditional small data services (such as voice, data services, etc.) to multimedia ( For example, pictures, streaming media, cloud services, etc.) are transformed as the center, and these emerging business requirements need to further improve network capacity and user service experience in operation. In order to cope with the rapid growth of mobile data service traffic, operators have proposed the deployment of small cells (Small cell/small eNB), that is, in places where there are many users using User Equipment (UE), such as supermarkets and shopping malls In other places, small cells with smaller coverage areas are densely deployed to support huge services generated in this area, so that more UEs can enjoy wider bandwidth and higher-speed data services. The access node of the small cell may be a Low Power Node (LPN for short), an indoor base station (Femtocell), a small base station (Picocell), a wireless fidelity (wireless fidelity, WI-FI for short) access point (Access Point) Point, referred to as AP) and so on.

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

However, in the prior art, the UE can only camp on one cell, and the camped cell will not be notified after camping, resulting in a large delay in establishing a link when the UE is used to provide wireless backhaul transmission. Inability to respond quickly when capacity is limited.

Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In the embodiment of the present invention, it is proposed to use a UE relay (relay) device as a relay to support the wireless backhaul of a macro cell (macro eNB) and a small cell (small eNB). This method requires the UE relay device to camp at the same time. Staying in two cells can better improve the wireless backhaul capacity. While implementing this wireless backhaul approach, traditional backhaul can coexist.

FIG. 1 is a schematic flowchart of Embodiment 1 of a method for camping on a UE relay device provided by the present invention. As shown in FIG. 1 , the method includes:

S101. 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 received signal quality value of the first cell.

S102, the UE relay device measures the received signal quality value of the second cell of the second cell supporting the UE relay device. After the UE relay device camps on the first cell, it will further select a second cell suitable for camping, which is specifically determined by measuring the received signal quality value of the second cell of the second cell.

S103. The UE relay device determines to camp in the second cell according to the received signal quality value of the second cell, or the UE relay device determines to camp in the second cell according to the received signal quality value of the first cell and the second cell received signal quality value of the first cell. The signal quality value is determined to camp in the above-mentioned second cell.

Generally, whether to camp on the second cell may be determined only according to the received signal quality value of the second cell. More preferably, since the UE relay device needs to camp on the first cell and the second cell at the same time, after the UE relay device camps on the first cell, it can simultaneously combine the reception with the first cell when selecting the second cell to camp on. The signal quality value and the received signal quality value of the second cell are determined.

S104 , 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 to camp on, so as to complete camping on two cells at the same time, and notifies the camped on result to the camped on the second cell. The first cell and the second cell, so that in the subsequent communication process, if the traditional backhaul of the first cell and the second cell is limited, the first cell or the second cell can camp on the first cell and the second cell simultaneously from One or more UE relay devices are activated in the UE relay device list of the device as the transmission support of the wireless backhaul, which realizes the improvement of the wireless backhaul capacity and solves the problem of limited backhaul.

After the above-mentioned 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 above-mentioned UE relay device notifies the first cell and the second cell of the camping result. Two ways:

One way is that the UE relay device sends a first camping result message to the first cell, where the first camping result message includes: the UE relay device identification and the second cell identification. Then, the first cell sends the second camping result message carrying the UE relay device identifier to the second cell.

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

In this way, when the backhaul is limited, the first cell and the second cell know which UE relay devices are camped in, and then the first cell or the second cell can activate the camped UE to support 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 receives broadcast information of any cell; and the UE relay device determines whether the broadcast information carries information that supports the UE The second cell list of the relay device, if yes, the cell is used as the first cell, the broadcast information is used as the first broadcast information, and the list of second cells supporting the UE relay device is parsed from the first broadcast information. Otherwise, the broadcast information will be discarded, and no further analysis is necessary. It should be noted that the above list may be carried in an information element (Information Element, IE for short) of broadcast information. In addition, after using the above cell 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 received signal quality of the first cell.

FIG. 2 is a schematic flowchart of Embodiment 2 of a method for camping on a UE relay device provided by the present invention. Taking the first cell as an eNB and the second cell as a relay node (Relay Node, RN for short) as an example, the above method include:

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

S202, the UE relay device determines whether the first broadcast information carries a list of RNs supporting the UE relay device, and if so, executes S203, otherwise the broadcast information is discarded.

S203 , the UE relay device parses the above-mentioned RN list supporting the UE relay device.

S204 , the UE relay device measures the first received signal quality value of the eNB, and determines to reside 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 will reside on the eNB side. It should be noted that the eNB is the eNB that sends the above-mentioned first broadcast information.

S205: The UE relay device measures the 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 reside on the above-mentioned RN side according to the above-mentioned first signal reception quality and the second received signal quality.

S207, the UE relay device notifies the eNB of the camping result. The camping result includes a UE relay device identity (Identity, ID for short) and an RN ID.

S208. The eNB notifies the RN of the camping result. The camping result includes the UE relay device ID.

Of course, S208 can also be replaced by the UE relay device notifying the RN of the camping result, where the camping result includes the UE relay device ID. In this case, the execution of S207 and S208 can be performed in no particular order.

Further, before the above-mentioned UE relay device determines to camp in the first cell, the UE relay device may also obtain the first cell that supports the UE relay device by means of Operations Administration and Management (OAM for short) list. Specifically, the above-mentioned list of the first cell is obtained through a mechanism similar to the existing RN obtaining the list of eNBs supporting the RN function. The mechanism is specifically that the RN first initiates a contact (attach) with any eNB as a common UE, and then uses the OAM method to obtain the list. Get a list.

Correspondingly, the above-mentioned UE relay device may obtain the list of second cells supporting the UE relay device by means of OAM.

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, and the target first cell supports the UE relay device. The above-mentioned 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 can be configured by the high-level device to create and maintain a list of second cells that support the UE relay device according to the historical residency information. Cell identity (Physical Cell Identity, PCI for short), cell frequency and other information, the UE relay device can determine the target that can reside by comparing its current geographic location with the geographic location information of each second cell in the list Second district. Specifically, the second cell whose geographic location is less than a certain range from the current geographic location of the UE relay device may be 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 judgment parameter from the second broadcast information. The same is true for the first cell, and details are not repeated here.

The manners of obtaining the first cell list and the second cell list in the foregoing embodiment may be mixed, which is not limited in this embodiment. For example, when there is no historical residency information, the first cell list and the second cell list supporting the UE relay device can be obtained through OAM, and then the target first cell and the target second cell are determined according to the current geographic location information. If the high-level device creates and maintains the first cell list and the second cell list according to the historical residency information, then it is no longer necessary to obtain the OAM method, and can directly determine the target first cell and the target second cell according to the current geographic location information. .

FIG. 3 is a schematic flowchart of Embodiment 3 of a method for camping on a UE relay device provided by the present invention. Taking the first cell as an eNB and the second cell as a relay node (Relay Node, RN for short) as an example, this method include:

S301 , the UE relay device obtains a list of eNBs supporting the UE relay device by means of OAM. In this embodiment, it is assumed that there is no historical residency information, and the eNB list needs to be acquired by means of OAM.

S302, the UE relay device determines the target eNB according to the current geographic location.

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

S304: The UE relay device determines, according to the first received signal quality value, to reside on the above-mentioned target eNB side. When the first received signal quality value satisfies the preset condition, the UE relay device will reside on the eNB side.

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

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

S307: The UE relay device determines, according to the second received signal quality, to reside on the above-mentioned target RN side.

It should be noted that, S307 may be replaced by the UE relay device determining to reside on the above-mentioned target RN side according to the above-mentioned first signal reception quality and the second received signal quality.

S308 , the UE relay device notifies the above-mentioned target eNB camping result. The camping result includes the UE relay device identity (Identity, ID for short) and the RN ID of the target RN.

S309, the eNB notifies the above-mentioned target RN camping result. The camping result includes the UE relay device ID.

Of course, S309 can also be replaced by the UE relay device notifying the RN of the camping result, and the camping result includes the UE relay device ID. In this case, the execution of S308 and S309 can be performed in no particular order.

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

It should be noted that, the above-mentioned quality threshold of the signal received by the second cell may be obtained from broadcast information sent by the second cell.

In another manner, the UE relay device determines to camp in the second cell according to the received signal quality value of the first cell and the received signal quality value of the second cell, specifically: the received signal quality value of the first cell is greater than If the received signal quality threshold of the first cell is higher, and the received signal quality value of the second cell is greater than the received signal quality threshold of the second cell, it is determined to camp in the second cell according to a preset criterion.

There may be various manners for the foregoing preset criteria, which are not limited in this embodiment of the present invention. For example, the above-mentioned determination of camping in the above-mentioned second cell according to the preset criteria may be judging that the absolute value of the difference between the received signal quality value of the first cell and the above-mentioned second cell's received signal quality value is less than or equal to the first absolute threshold value. , the UE relay device resides in the second cell. The first absolute threshold may include: a first RSRQ absolute threshold and a first RSRP absolute threshold.

Further, on the basis of the above-mentioned embodiment, the above-mentioned first received signal quality value includes: a first reference signal receiving power (Reference Signal Receiving Power, RSRP for short) value (referred to as RSRP ₁ ) and the first reference signal received quality value (Reference Signal Received Quality, RSRQ for short) value (referred to as RSRQ ₁ ), or the above-mentioned first received signal quality value includes: first RSRP ₁ . Correspondingly, the first cell received 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 received signal quality value of the second cell includes: a second RSRP value (referred to as RSRP ₂ ) and a second RSRQ value (referred to as RSRQ ₂ ); or, the received signal quality of the second cell includes: a second RSRP value. Correspondingly, the above-mentioned second cell received signal quality threshold includes: a second RSRP threshold and a second RSRQ threshold, or the above-mentioned second cell received signal quality threshold includes: a second RSRP threshold.

It should be noted that the above-mentioned RSRP threshold and RSRQ threshold may be obtained from broadcast information of the corresponding cell. There is no restriction here.

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

Correspondingly, the above-mentioned second cell received signal quality value is greater than the second cell received signal quality threshold, which may be specifically: the second RSRP is greater than the second RSRP threshold, and the second RSRQ is greater than the second RSRQ threshold. If the RSRQ threshold is not obtained, the determination is made only according to the RSRP, that is, the above-mentioned second cell received signal quality value is greater than the second cell received signal quality threshold, which may be specifically: the second RSRP is greater than the second RSRP threshold.

Correspondingly, the above-mentioned UE relay device determines to camp in the second cell according to the received signal quality value of the first cell and the received signal quality value of the second cell, specifically: if RSRP ₂ is greater than the second RSRP threshold, and RSRQ ₂ If the value is greater than the second RSRQ threshold, the UE relay device further determines to camp in the above-mentioned second cell according to the preset criterion.

For example, the UE relay device determines to camp in the second cell according to a preset criterion, which may be: judging whether the absolute value of the difference between the RSRP ₁ and RSRP ₂ (referred to as |RSRP ₁ -RSRP ₂ |) is not Less than or equal to the first RSRP absolute threshold, whether the absolute value of the difference between RSRQ ₁ and RSRQ ₂ (denoted as |RSRQ ₁ -RSRQ ₂ |) is less than or equal to the first RSRQ absolute threshold. If |RSRP ₁ -RSRP ₂ | is less than or equal to the first RSRP absolute threshold, and |RSRQ ₁ -RSRQ ₂ | is less than or equal to the first RSRQ absolute threshold, the UE relay device camps in the second cell. Similarly, in the case where the RSRQ threshold is not obtained, the judgment may be made only according to the RSRP, that is, the UE relay device determines to camp in the second cell according to the preset criterion, which may be: judging the difference between the RSRP ₁ and the RSRP ₂ Whether the absolute value of the difference (denoted as |RSRP ₁ -RSRP ₂ |) is less than or equal to the first RSRP absolute threshold, if |RSRP ₁ -RSRP ₂ | is less than or equal to the first RSRP absolute threshold, the UE relay device camps on in the above-mentioned second cell.

The first RSRP absolute threshold and the first RSRQ absolute threshold may also be obtained from broadcast information of the corresponding cell, but are not limited thereto.

In the embodiment of the present invention, if the UE wants to notify to camp on two cells, it selects two cells whose RSRP values and RSRQ values are close enough as possible.
