technical field

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

In order to make UMTS applicable to different frequency bandwidths, a scalable universal mobile telecommunications system S-UMTS (Scalable Universal Mobile Telecommunications System) cell technology is introduced. S-UMTS may also be referred to as a fractional-universal mobile telecommunications system F-UMTS (Fractional-Universal Mobile Telecommunications System).

S-UMTS cell technology is still considered as a UMTS cell technology, but its bandwidth is lower or higher than UMTS cell bandwidth (5MHz or 4.2MHz). In the prior art, the bandwidth of S-UMTS cell is usually set as UMTS One-Nth of the cell bandwidth, and the power of the S-UMTS cell is one-Nth of that of the UMTS cell, where N is a scaling factor, for example, the value of N can be 2, 4, 0.5, 0.25, etc.

When the user equipment UE (User Equipment) accesses the network from an unconnected network state, since the bandwidth of the S-UMTS cell is an uncertain value, no matter whether the network side issues 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, which causes the UE to measure and The measurement time when selecting an S-UMTS cell is long, or the UE cannot know the frequency range of the S-UMTS cell after the measurement, so that there is a certain time delay for the UE to select the S-UMTS cell, or the UE cannot measure and select the S-UMTS cell.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Embodiment one,

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

101. The user equipment selects a Universal Mobile Telecommunications System UMTS cell as a serving cell of the user equipment.

When the UE changes from a non-access network to an access network, for example, when the UE switches from a power-on state to an access network, the UE searches for UMTS cells on any current frequency point with a 5M bandwidth, and searches for The UMTS cell is measured to obtain a 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 a serving cell of the UE.

102. The UE acquires scalable bandwidth S-UMTS cell information in neighboring cell information delivered by the network side, 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 information of neighboring cells of the current serving cell of the UE through the system information delivered by the network side. The neighboring cell information includes at least one of UMTS cell information and S-UMTS cell information.

Specifically, the S-UMTS cell information may be delivered in system information such as a system information block (SIB) 11, or SIB11bis, or SIB12.

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

The network side may allocate a separate information element for the S-UMTS cell in the measurement control system message in the system information block to deliver the S-UMTS cell information, or may assign a separate information element to the S-UMTS cell in the measurement control system message in the system information block. The information element 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; it may also be frequency point information and a scaling factor N.

Wherein, the frequency range refers to the frequency range in which the S-UMTS cell at a certain frequency point works. The frequency point information includes: a start frequency point, a center frequency point and an end frequency point. The scaling factor N indicates that the bandwidth of the S-UMTS cell is N/N of the bandwidth of the UMTS cell, where 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 also 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 range of the S-UMTS cell at a certain frequency point can be obtained through the frequency point information and the scaling factor N.

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 Then 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, it can be known that the bandwidth of the S-UMTS cell is 2.5MHz; When the center frequency point is 2000MHz, it can be determined that the frequency range of the S-UMTS cell is 1998.75MHz-2001.25MHz.

Of course, it should be noted that the method for the UE to obtain the frequency range of the S-UMTS cell according to any two items of the scaling factor N, the start frequency point, the end frequency point and the center frequency point is understood by those skilled in the art. technical solution, the embodiments of the present invention will not be repeated here.

Optionally, when there is only an S-UMTS cell with one bandwidth in the adjacent cell, that is, the N value is known, the network side does not need to send the N value, and the adjacent cell information may only carry the frequency point of the S-UMTS cell Information, so that the UE can obtain the frequency range of the S-UMTS cell through the frequency point information, and then measure the S-UMTS cell according to the frequency range of the S-UMTS cell.

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

When the UE receives S-UMTS cell information in the system information, or receives an indication to select an S-UMTS cell in the system information, the UE In the 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 the 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, and the like.

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

If the neighboring cell information includes the S-UMTS cell, the UE may select the S-UMTS cell as the serving cell without considering whether the signal quality of the S-UMTS cell is higher than the signal quality of the UE's current serving cell.

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

Optionally, on the basis of satisfying the first condition, in order to make the signal of the S-UMTS cell selected by the UE better, the UE judges the signal quality value in the measurement result of the S-UMTS cell that meets the first condition Whether it is greater than the first preset signal quality threshold. If there is an S-UMTS cell with a signal quality value greater than the first preset signal quality threshold, the UE selects any S-UMTS cell greater than the first preset signal quality threshold as the UE's serving cell. The first preset signal quality threshold is greater than the preset threshold in the first condition.

Optionally, in order to make it easier for the UE to select an S-UMTS cell, the preset threshold in the first condition may be made smaller; or the preset threshold in the first condition may not be set limit, so that the UE can select the S-UMTS cell as the serving cell of the UE if it detects the S-UMTS cell.

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

201. The network side delivers neighboring cell information to the UE, and the S-UMTS cell information in the neighboring cell information includes the frequency range information of the S-UMTS cell, so that after the UE selects the UMTS cell as the serving cell, it can Acquiring the frequency range information of the S-UMTS cell, measuring the S-UMTS cell according to the frequency range information of the S-UMTS cell, and selecting the 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 area through system information. When there is an S-UMTS cell in the neighboring cell of the currently serving cell of the user equipment, 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 above S-UMTS cell. After receiving the neighboring cell information, the UE obtains the frequency range information of the S-UMTS cell in the neighboring cell information.

The frequency range information of the S-UMTS cell includes: frequency range or frequency point information and a scaling factor N, the scaling factor N indicates that the bandwidth of the S-UMTS cell is N fractions of the bandwidth of the Universal Mobile Telecommunications System UMTS cell one.

Wherein, the frequency range refers to the frequency range in which the S-UMTS cell at a certain frequency point works. The frequency point information includes: a start frequency point, a center frequency point and an end frequency point. The scaling factor N indicates that the bandwidth of the S-UMTS cell is N/N of the bandwidth of the UMTS cell, where 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 also 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.

Optionally, when there is only an S-UMTS cell with one bandwidth in the adjacent cell, that is, the N value is known, the network side does not need to send the N value, and the adjacent cell information may only carry the frequency point of the S-UMTS cell Information, so that the UE can measure the S-UMTS cell through the 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 Selecting the S-UMTS cell in the neighboring cell information as the serving cell of the UE.

Optionally, the network side may also send selected camping policy information to the UE, where the selected camping policy information includes: a selection threshold and/or a second signal quality threshold. so that the UE selects the S-UMTS cell in the neighboring cell information as the serving cell of the UE according to the selected camping policy information and the measurement result.

The above describes the technical solution for the UE in the S-UMTS cell to obtain the measurement result by measuring the downlink signal. The problem of detecting the UE uplink signal in the S-UMTS cell by the network side is described in detail below.

The uplink and downlink frequency interval of the UMTS cell is fixed, so the network side does not need to configure the uplink and downlink frequency interval information, but in the S-UMTS cell, the uplink and downlink frequency interval of the S-UMTS cell has not yet been 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 know the uplink and downlink frequency interval of the S-UMTS cell. Frequency Range.

Specifically, the uplink and downlink frequency interval information or 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 (Global System for Mobile Communications), General Packet Radio Service GPRS (General Packet Radio Service), Code Division Multiple Access 2000CDMA2000 (Code Division Multiple Access 2000), time division Synchronous Code Division Multiple Access TD-SCDMA (Time Division Synchronous Code Division Multiple Access), Long Term Evolution (Long Term Evolution), Wireless Local Area Networks (WLANs), Wireless Fidelity WiFi (Wireless Fidelity) and Global Microwave Interconnection Access to wireless networks such as WiMAX (Worldwide Interoperability for Microwave Access). Especially in the scenario where these wireless systems are distributed with micro cell base stations.

The UE first selects a UMTS cell as the serving cell of the UE; then, obtains the S-UMTS cell in the neighboring cell information issued by the network side information, and measure the S-UMTS cell to obtain a measurement result; then, according to the obtained measurement result, select the S-UMTS cell as the serving cell of the user equipment. After the UE selects the UMTS cell as the serving cell of the UE, it can obtain the S-UMTS cell information through the neighboring cell information of the UMTS cell without measuring the bandwidth of the S-UMTS cell, so that the UE can quickly measure and select The S-UMTS cell is the serving cell of the UE.

305. The UE selects an S-UMTS cell as a serving cell of the UE according to the measurement result of the S-UMTS cell and the selected camping policy information.

If the neighboring cell information includes the S-UMTS cell, the UE may select the S-UMTS cell as the serving cell without considering whether the signal quality of the S-UMTS cell is higher than the signal quality of the UE's current serving cell.

If the random number is greater than the selection threshold, the UE selects the S-UMTS cell as a serving cell of the UE.

Optionally, in order to make the cell signal quality of the S-UMTS cell selected by the UE better, after the UE obtains the measurement result of the S-UMTS cell, the UE judges the signal quality in the measurement result Whether the value is greater than the second preset signal quality threshold. If the signal quality value of the S-UMTS cell is greater than the second preset signal quality threshold value, the UE selects the S-UMTS cell as the serving cell of the UE. The second signal quality threshold is greater than the first signal quality threshold.

Optionally, in order to prevent each S-UMTS cell from being overloaded and avoid ping-pong caused by poor signal quality, the user equipment randomly generates a random number. If the random number randomly generated by the user equipment is greater than the selection threshold, and the signal quality value in the measurement result is greater than the preset second signal quality threshold, the user equipment selects the S-UMTS cell as The serving cell of the user equipment.

If so, the processor 61 selects the S-UMTS cell as the serving cell of the UE.

In order to prevent each S-UMTS cell from being overloaded, the processor 61 judges whether the signal quality value in the measurement result is greater than a first preset signal quality threshold value; and in the measurement result of the S-UMTS cell After the signal quality value is greater than the first preset signal quality threshold value, the processor 61 generates a random number to determine whether the random number is greater than the selection threshold value. If the random number is greater than the selection threshold, the processor 61 selects the S-UMTS cell as the serving cell of the UE.

Therefore, the processor 61 is specifically configured to generate random numbers.

If the signal quality value of the S-UMTS cell is greater than the second preset signal quality threshold value, the processor 61 selects the S-UMTS cell as the serving cell of the UE. The second signal quality threshold is greater than the first signal quality threshold.

Therefore, the processor 61 is specifically configured to select the S-UMTS cell as the serving cell of the UE if the signal quality value in the S-UMTS cell measurement result is greater than the second signal quality threshold.

Optionally, in order to prevent each S-UMTS cell from being overloaded and avoid ping-pong caused by poor signal quality, after the measurement unit 43 obtains the measurement result of the S-UMTS cell, the user equipment randomly generates a random number.
