Description

Method, device and user equipment for selecting scalable bandwidth cell

The present invention relates to the field of communications, and in particular, to a method, a device, and a user equipment for a scalable bandwidth cell.

Background technique

At present, the bandwidth of the Universal Mobile Telecommunications System (UMTS) is fixed. In order to make UMTS applicable to different frequency bandwidths, a scalable Universal Mobile Telecommunications System (S-UMTS) cell technology is introduced. The S-UMTS may also be referred to as a Fractional-Universal Mobile Telecommunications System (F-UMTS).

The S-UMTS cell technology is still considered to be a UMTS cell technology, except that its bandwidth is lower or higher than the UMTS cell bandwidth (5 MHz or 4.2 MHz). In the prior art, the bandwidth of the S-UMTS cell is usually set to UMTS. One-ninth of the bandwidth of the cell, and the power of the S-UMTS cell is one-N of the UMTS cell, and N is a scaling factor. For example, the value of N may be 2, 4, 0.5, 0.25, and the like.

When the user equipment UE (User Equipment) is connected to the network, the bandwidth of the S-UMTS cell is an indeterminate value, regardless of whether the network side delivers the frequency range of the S-UMTS cell to the UE. The UE needs to measure the bandwidth of the target S-UMTS cell multiple times to determine the frequency range of the target S-UMTS cell. It is possible that after the measurement, the frequency range of the S-UMTS cell cannot be selected, thus causing the UE to measure and When the S-UMTS cell is selected, the measurement time is long, or the UE does not know the frequency range of the S-UMTS cell after the UE passes the measurement, so that the UE selects the S-UMTS cell to have a certain delay, or the UE cannot measure and select the S- UMTS cell.

detailed description

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. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all 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.

Embodiment 1

An embodiment of the present invention provides a method for selecting a scalable bandwidth cell. The method is performed by a user equipment. As shown in FIG. 1, the method includes:

101. The user equipment selects a universal mobile communication system. The UMTS cell is a serving cell of the user equipment.

When the UE is connected to the network by the non-access network, for example, when the UE is from the power-on state to the access network, the UE searches for any current frequency point with 5M bandwidth. And determining, by the UMTS cell, the signal quality value of the UMTS cell, and when the signal quality value of the searched UMTS cell meets a preset signal quality threshold, the UE selects the UMTS cell as The serving cell of the UE.

102. The UE acquires scalable bandwidth S-UMTS cell information in the neighbor cell information that is sent by the network, where the S-UMTS cell information includes frequency range information of the S-UMTS cell.

After the UE selects the UMTS cell as the serving cell of the UE, the UE can obtain the neighbor cell information of the current serving cell of the UE by using the system information delivered by the network side. The neighbor cell information includes at least one of UMTS cell information and S-UMTS cell information.

Specifically, the S-UMTS area information may be sent in system information such as a system information block (SIB), or a SIB lbis, or SIB 12.

When there is an S-UMTS cell in the neighboring cell of the current serving cell of the UE, the neighboring cell information sent by the network side includes the S-UMTS cell information.

The network side may allocate a separate cell to the S-UMTS cell in the measurement control system message in the system information block to deliver the S-UMTS cell information, or may be a measurement control system in the system information block. The cell allocated for the UMTS cell in the message is used to deliver the S-UMTS cell information.

Specifically, the frequency range information of the S-UMTS cell may be a frequency range; and may also be frequency point information and a scaling factor N.

The frequency range refers to the frequency range in which the S-UMTS cell operates at a certain frequency point. The frequency point information includes: a starting frequency point, a center frequency point, and an ending frequency point. The scaling factor N indicates that the bandwidth of the S-UMTS cell is one-Nth of the bandwidth of the UMTS cell, and the N is any real number greater than 0, and the bandwidth of the UMTS cell is 5M or 4.2M.

Optionally, the S-UMTS cell information may further include a cell scrambling code. The cell scrambling code is used to distinguish different cells and channels, so that the UE can quickly acquire downlink pilot signals and complete the cell search process.

The frequency point information and the scaling factor N can be used to obtain a certain frequency point S-UMTS cell Frequency Range.

For example, if the frequency range information is the scaling factor N and the center frequency point, the bandwidth of the S-UMTS cell may be determined according to the scaling factor N, and then according to the center frequency point and the bandwidth. The frequency range of the S-UMTS cell can be obtained.

For example, when the N value in the S-UMTS cell information in the neighbor cell information is 2, the bandwidth of the S-UMTS cell is 2.5 MHz; when the S-UMTS cell is sent by the network side When the center frequency is 2000 MHz, the frequency range of the S-UMTS cell can be determined to be 1998.75 MHz to 2001.25 MHz.

It should be noted that the method for obtaining the frequency range of the S-UMTS cell by the UE according to the scaling factor N, the starting frequency point, the ending frequency point, and the center frequency point is known to those skilled in the art. The technical solutions of the present invention are not described herein again.

Optionally, when there is only one bandwidth of the S-UMTS cell in the neighboring cell, that is, the N value is known, the network side does not need to send an N value, and the neighbor cell information may only carry the frequency of the S-UMTS cell. The information is such that the UE can obtain the frequency range of the S-UMTS cell by using frequency point information, and then measure the S-UMTS cell according to the frequency range of the S-UMTS cell.

103. The UE performs measurement on the S-UMTS cell in the neighbor cell information according to the frequency range information of the S-UMTS cell included in the neighbor cell information, and obtains a measurement result of the S-UMTS cell.

After the UE receives the S-UMTS cell information in the system information, or receives an indication of selecting the S-UMTS cell in the system information, the UE according to the S-UMTS cell obtained from the neighbor cell information a frequency range, the S-UMTS cell in the neighboring cell is measured, and the measurement result of the S-UMTS cell is obtained.

Specifically, the UE measures the signal quality of the S-UMTS cell in the neighboring cell according to the frequency range information of the S-UMTS cell, and obtains a signal quality value of the S-UMTS cell.

The signal quality value may specifically be: pilot reference signal received power RSRP (Reference Signal Receiving Power), path loss value, pilot signal to noise ratio Ec/N0, etc.

104. The UE selects, according to the measurement result of the S-UMTS cell, an S-UMTS cell as a serving cell of the UE.

If the neighboring cell information includes the S-UMTS cell, the UE may select the S-UMTS cell as the serving cell, and may not consider whether the signal quality of the S-UMTS cell is higher than the signal quality of the current serving cell of the UE.

Specifically, the UE selects whether the measurement result of the S-UMTS cell meets the first condition, where the first condition is specifically: the S-UMTS cell RSRP is greater than a preset threshold, for example, the threshold value is -95 dBm. The S-UMTS cell is not a cell that is prohibited from accessing. If yes, the UE selects the S-UMTS cell as the serving cell of the UE.

Optionally, on the basis that the first condition is met, in order to make the signal of the S-UMTS cell selected by the UE better, the UE determines a signal quality value in the measurement result of the S-UMTS cell that satisfies the first condition. Whether it is greater than the first preset signal quality threshold. If there is an S-UMTS cell whose signal quality value is greater than the first preset signal quality threshold, the UE selects any S-UMTS cell that is greater than the first preset signal quality threshold as described above. The serving cell of the UE. The first preset signal quality threshold is greater than a preset threshold in the first condition.

Optionally, in order to enable the UE to select the S-UMTS cell more easily, the preset threshold value in the first condition may be made smaller; or the preset gate in the first condition may not be set. The limit value is such that the UE can select the S-UMTS cell as the serving cell of the UE as long as the S-UMTS cell is detected.

The embodiment of the present invention provides a method for selecting a scalable bandwidth cell. As shown in FIG. 2, the execution body of the method is a network side, for example, a Radio Network Controller (RNC).

The network side sends the neighboring cell information to the UE, where the S-UMTS cell information in the neighbor cell information includes the frequency range information of the S-UMTS cell, so that the UE selects the UMTS cell as the serving cell, and can Obtaining frequency range information of the S-UMTS cell, according to the frequency range information of the S-UMTS cell The S-UMTS cell performs measurement, and selects an S-UMTS cell as the serving cell of the UE according to the measurement result.

The network side sends neighbor cell information to UEs within its coverage by using system information. When the user equipment has an S-UMTS cell in the neighboring cell of the current serving cell, the neighboring cell information includes S-UMTS cell information, and the S-UMTS cell information includes the S-UMTS cell information including the The frequency range information of the S-UMTS cell. After receiving the neighbor cell information, the UE acquires frequency range information of the S-UMTS cell in the neighbor cell information.

The frequency range information of the S-UMTS cell includes: a frequency range, or frequency point information, and a scaling factor N, where the scaling factor N indicates that the bandwidth of the S-UMTS cell is N of the bandwidth of the UMTS cell of the universal mobile communication system. one.

Optionally, when there is only one bandwidth of the S-UMTS cell in the neighboring cell, that is, the N value is known, the network side does not need to send an N value, and the neighbor cell information may only carry the frequency of the S-UMTS cell. Information, such that the UE can measure the S-UMTS cell by using frequency point information.

After acquiring the frequency range information of the S-UMTS cell in the neighbor cell information, the UE measures the S-UMTS cell according to the frequency range information of the S-UMTS cell, obtains a measurement result, and according to the measurement result The S-UMTS cell in the neighbor cell information is selected as the serving cell of the UE.

Optionally, the network side may further send the selected camping policy information to the UE, where the selecting the camping policy information includes: selecting a threshold value and/or a second signal quality threshold. So that the UE selects according to the selected camping policy information and the measurement result. The S-UMTS cell in the neighbor cell information is selected as the serving cell of the UE.

The technical solution for obtaining the measurement result by the UE in the S-UMTS cell by measuring the downlink signal is described above. The following describes the problem of the UE side detecting the UE uplink signal of the S-UMTS cell.

The uplink and downlink frequency intervals of the UMTS cell are fixed. Therefore, the uplink and downlink frequency interval information of the S-UMTS cell is not determined. Therefore, the network side needs to configure the uplink and downlink frequency interval information, or the UE uplink transmission frequency band information, so that when the uplink and downlink frequency intervals of the S-UMTS cell are different, the network side can learn the uplink and downlink of the S-UMTS cell. Frequency Range.

Specifically, the uplink and downlink frequency interval information or the UE uplink transmission frequency band information may be included in a cell establishment request, a cell reconfiguration request, a public measurement start request, and a dedicated measurement start request message.

In addition to the UMTS network introduced in the scheme, the present invention is equally applicable to Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), and Code Division Multiple Access (2000). , Time Division Synchronous Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), and the world. The microwave interconnects wireless networks such as WiMAX (Worldwide Interoperability for Microwave Access). In particular, these wireless systems are distributed with scenes of microcell base stations.

An embodiment of the present invention provides a method for selecting a scalable bandwidth cell, where the UE first selects a UMTS cell as a serving cell of the UE; and then acquires an S-UMTS cell in the neighbor cell information that is sent by the network side. The information is measured by the S-UMTS cell to obtain a measurement result. Then, according to the obtained measurement result, the S-UMTS cell is selected as the serving cell of the user equipment. After the UE selects the UMTS cell as the serving cell of the UE, it can pass the neighbor cell information of the UMTS cell. The S-UMTS cell information is obtained, and the bandwidth of the S-UMTS cell does not need to be measured, so that the UE can quickly measure and select the S-UMTS cell as the serving cell of the UE.
