Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of 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, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a schematic diagram of a communication system according to an embodiment of the present invention. As shown in fig. 1, the communication system provided in this embodiment includes a User Equipment (UE) 101 and a network device 102.
Where UE101 refers to a device that can access network device 102 through a wireless communication network, including a mobile terminal, tablet, wearable device, etc. In addition, the UE101 may also be a device dedicated to unlicensed frequency measurements.
The network device 102, i.e. public mobile communication network device, is an interface device for the UE101 to access the internet, and is also a form of a radio station, which refers to a radio transceiver station that performs information transfer with the UE101 in a certain radio coverage area.
In the embodiment of the present invention, the UE101 is communicatively connected to the network device 102 through a wireless communication network, and the method for measuring the unlicensed frequency in the embodiment of the present invention may be performed by the UE101, or may be performed by the network device 102, or may be performed by both the UE101 and the network device 102. For example, in some embodiments, the UE101 sends an early measurement report to the network device 102; upon receiving the early measurement report, the network device 102 generates a task item corresponding to the early measurement report. The following will explain in detail the embodiments.
Referring to fig. 2, fig. 2 is a flowchart of a method for measuring an unlicensed frequency according to an embodiment of the present invention, where an execution subject of the embodiment is UE101 in the embodiment shown in fig. 1, and the method includes:
s201, early measurement is carried out on unlicensed frequencies to obtain early measurement reports, and the early measurement reports comprise received signal strength indication and channel occupancy rate of the unlicensed frequencies.
In the embodiment of the invention, when the service is needed, the network equipment needs to configure CA and/or MR-DC for the UE. When the UE enters an IDLE state (i.e., rrc_idle state) or a connection INACTIVE state (i.e., rrc_inactive state), the network device may issue a measurement configuration to the UE to measure neighboring frequencies, which may be unlicensed frequencies.
For example, the network device sends an early measurement configuration to the UE through radio resource control (Radio Resource Control, RRC) signaling, causing the UE to measure the unlicensed frequency F1. After receiving the early measurement configuration sent by the network device, the UE enters an rrc_idle state or an rrc_inactive state, camps in a cell with a frequency of Fs, and then performs early measurement on the unlicensed frequency F1 to obtain an early measurement report, where the early measurement report includes a received signal strength indication (Received Signal Strength Indicator, abbreviated as RSSI) and a channel occupancy of the unlicensed frequency F1.
S202, reporting the early measurement report to network equipment.
In the embodiment of the invention, after receiving an early measurement report reported by the UE, the network equipment configures CA and/or MR-DC for the UE based on the early measurement report.
Specifically, in the embodiment of the present invention, CA configuration and/or MR-DC configuration may be performed on the UE only when the RSSI is lower than the preset strength threshold and the channel occupancy is lower than the preset occupancy threshold.
Wherein the RSSI and channel occupancy facilitate the network device to discover hidden nodes and make channel selections. If the RSSI and channel occupancy are high, this indicates that the interference experienced on that frequency is large and that it is not appropriate to conduct traffic on that frequency.
According to the measuring method of the unlicensed frequency, provided by the embodiment of the invention, the UE performs early measurement on the unlicensed frequency to obtain an early measurement report, and reports the early measurement report to the network equipment, wherein the early measurement report comprises the received signal strength indication and the channel occupancy rate of the unlicensed frequency; the network device performs CA configuration and/or MR-DC configuration on the UE according to the early measurement report. Compared with the prior art, the early measurement report reported by the UE to the network device in the embodiment of the present invention further includes RSSI and channel occupancy, and besides satisfying the existing reference signal received power and reference signal received quality conditions, the network device needs to perform CA configuration and/or MR-DC configuration on the UE only when the RSSI and channel occupancy satisfy certain conditions, thereby configuring appropriate CA and/or MR-DC for the user device.
Further, based on the description of the foregoing embodiment, in the embodiment of the present invention, the early measurement report further includes an independent/non-independent networking (SA/NSA) identifier of the neighboring cell on the unlicensed frequency, a public land mobile network identifier (Public Land Mobile Network ID, PLMN ID) and a global cell identifier (Cell Global Identifier, CGI).
Specifically, before generating the early measurement report, the UE also measures the SA/NSA identifier, the PLMN ID and the CGI of the neighboring cell on the unlicensed frequency, and then generates the early measurement report based on the RSSI, the channel occupancy SA/NSA identifier, the PLMN ID and the CGI, and uploads the early measurement report to the network device. The network device can sense the existence of the neighboring cells based on the SA/NSA identifier, PLMN ID and CGI, and can decide whether to perform CA configuration and/or MR-DC configuration on the UE based on the RSSI and the channel occupancy.
It should be appreciated that there may be different cells of the public land mobile network on the same unlicensed frequency and there may be a lack of coordination between the different operators, thereby causing PCI collisions or confusion. In the prior art, network equipment generally obtains PCIs of neighboring cells of a serving cell where the UE is currently located in a scanning manner, and selects different PCIs for the serving cell where the UE is currently located to avoid collision; alternatively, automatic neighbor relation (Automatic Neighbor Relation, ANR for short) is employed to detect and resolve PCI conflict and confusion problems. In the two modes, the network device can obtain the PCI, but the network device is required to actively acquire or configure the ANR for the UE, so that additional expense is inevitably brought to the network device.
In the embodiment of the invention, the UE can report the SA/NSA identifier, the PLMN ID and the CGI of the adjacent cell of the service cell where the UE is currently positioned to the network equipment through the early measurement report, so that the network equipment does not need to actively acquire or configure an automatic neighbor relation for the UE, and the cost of the network equipment can be effectively reduced.
Further, based on the description of the foregoing embodiments, in the embodiments of the present invention, the UE may be further configured, so that the network device may better perceive the existence of the neighboring cell. Specific configurations may include the following:
in the first mode, the UE is configured to perform early measurement on an unlicensed frequency to obtain an early measurement report even when the UE does not support CA and MR-DC between the unlicensed frequency and a serving frequency, where the serving frequency is a frequency of a serving cell where the UE is currently located.
In the prior art, when the UE does not support CA and MR-DC between the unlicensed frequency and the service frequency, the UE does not report the measurement result of the neighboring cell of the currently located service cell, which may cause that the network device cannot know the existence of the neighboring cell.
Through the first configuration, even when the UE does not support CA and MR-DC between the unlicensed frequency and the service frequency, the UE still performs early measurement on the unlicensed frequency to obtain an early measurement report and reports the early measurement report to the network equipment, so that the network equipment senses the existence of the adjacent cells, and the network equipment is beneficial to solving the PCI conflict and confusion problems.
For example, the network device broadcasts early measured unlicensed frequencies F1 and F2 in the system information, where the UE does not support CA between the serving frequency of the current serving cell and frequency F1, nor MR-DC, and the UE supports CA between the serving frequency of the current serving cell and frequency F2. After the network equipment triggers the UE to perform early measurement through the RRC release message, the UE still performs measurement on the frequency F1 to obtain and report an early measurement report, so that the network equipment can sense the existence of the adjacent cell on the frequency F1.
And secondly, configuring the UE in a second mode, and when the early measurement availability timer of the UE is overtime or the current service cell of the UE changes, the UE still keeps the measurement result corresponding to the adjacent cell on the detected unlicensed frequency.
In the prior art, when an early measurement validity timer (validity timer) expires or a serving cell in which the UE is currently located changes, the UE clears the obtained measurement result.
Through the second configuration, even if the measurement validity timer is overtime or the service cell where the UE is currently located changes, the UE still keeps the detected measurement result and reports the measurement result to the network equipment in good time, so that the network equipment is beneficial to solving the PCI conflict and confusion problems.
And thirdly, carrying out third configuration on the UE, and when the cell quality of any adjacent cell does not meet the preset quality threshold condition, reporting the measurement result of the adjacent cell to the network equipment by the UE still including the early measurement report.
In the prior art, the UE may report the measurement result of the neighboring cell only when the cell quality of the neighboring cell meets a preset quality threshold condition, and may not report the measurement result of the neighboring cell when the cell quality of the neighboring cell does not meet the preset quality threshold condition.
Through the third configuration, when the cell quality of any adjacent cell does not meet the preset quality threshold condition, the UE still reports the measurement result of the adjacent cell, namely the preset quality threshold condition is ignored in the measurement process, so that the problem of PCI conflict and confusion of network equipment is solved.
Further, based on the description of the foregoing embodiment, in the embodiment of the present invention, when early measurement is performed, a global cell identifier of a serving cell in which the UE is located is also obtained, and an association relationship between the global cell identifier and a measurement result of a neighboring cell of the serving cell is established; and then reporting the acquired global cell identification code of each service cell, the measurement result of the adjacent cell of each service cell and the correlation relationship to network equipment.
For example, when the UE measures the neighboring cells a1 and a2 in the serving cell a and then measures the neighboring cells B1 and B2 in the serving cell B, the UE reports the measurement results corresponding to the neighboring cells a1, a2, B1 and B2 and the global cell identification code of the cell A, B, correlates the measurement results of the neighboring cells a1 and a2 with the global cell identification code of the cell a, and reports the obtained correlation together after correlating the measurement results of the cells B1 and B2 with the global cell identification code of the cell B.
In the embodiment of the invention, when the UE reports the early measurement report, the UE can report the measurement results of the adjacent cells measured by the UE under a plurality of service cells and the global cell identification code of the service cell where the UE is positioned when measuring, thereby being convenient for the network equipment to identify the service cell corresponding to the received measurement results of the adjacent cells.
