Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a pilot frequency measurement method and apparatus.
Background
The development of wireless cellular technology has been progressing from The first Generation mobile communication (The 1st Generation, 1G) to The 2nd Generation mobile communication (The 2nd Generation, 2G), The 3rd-Generation mobile communication (3G), and The 4th Generation (4G) based on The Long Term Evolution (LTE) technology, which is The latest development, in order. Generally, a 3G-capable ue supports 2G simultaneously, and a 4G-capable ue supports 2G and 3G simultaneously. The user terminal simultaneously supporting multiple network systems is also called a multimode terminal, wherein the user terminal simultaneously supporting 2G, 3G and 4G is called an LTE multimode terminal.
The multimode terminal needs to support neighboring cell interoperation under different network systems, including inter-cell reselection of inter-system in an idle state, inter-cell redirection of inter-system in a connected state, and inter-cell handover of inter-frequency in a system, and the premise of realizing the neighboring cell interoperation is that a user terminal needs to perform inter-frequency neighboring cell measurement. Limited by the rf parameters, the inter-frequency measurement capability of the ue is usually limited, for example, some ues have the following maximum measurement capability: the pilot Frequency points that can be measured simultaneously are at most 3 Frequency Division Duplex (FDD) LTE Frequency points, 3 Time Division Long Term Evolution (Time Division Long Term Evolution, TD-LTE) Frequency points, 3 Wideband Code Division Multiple Access (WCDMA) Frequency points, and3 Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) Frequency points.
At present, under the network architecture of the inter-frequency networking, a network side is configured with a large number of inter-frequency neighboring frequency points, including inter-system frequency points. For example, the number of TD-SCDMA pilot frequency neighboring frequency points configured for a certain cell is not less than 9, and the number of configured TD-LTE pilot frequency neighboring frequency points is not less than 6, which greatly exceeds the maximum number of TD-SCDMA pilot frequency neighboring frequency points and TD-LTE pilot frequency neighboring frequency points that can be measured by a general user terminal, resulting in a situation that the number of pilot frequency neighboring frequency points configured on the network side is not matched with the measurement capability of the user terminal.
When the number of pilot frequency adjacent frequency points of a certain network system issued by the network side exceeds the maximum pilot frequency adjacent frequency point number of the network system supported by the user terminal, the user terminal can only take the first several frequency points within the maximum measuring capability range of the user terminal according to the measuring sequence issued by the network side to measure, and discard the frequency points exceeding the maximum measuring capability range. In this case, when the neighboring frequency points meeting the interoperability condition are arranged in the sequence, the neighboring frequency points are likely to be discarded by the user terminal, and the user terminal fails to perform the interoperability because the neighboring frequency points meeting the interoperability condition are not measured.

Detailed Description
In order to make the objects, 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 drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The following embodiments may be cited with each other without contradiction.
The embodiment of the invention can be used for pilot frequency adjacent cell measurement in communication systems of various network standards and pilot frequency adjacent cell measurement among different communication systems. Here, the communication systems of different network systems include: the 2nd Generation Mobile communication (2G) System based on The Global System for Mobile communications (GSM) and Code Division Multiple Access (CDMA), The 3rd Generation (3G) System based on Wideband Code Division Multiple Access (WCDMA), CDMA2000 and Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), and The 4th Generation (4G) System based on Long Term Evolution (LTE) technology, which are newly developed, and The like.
The basic idea of the embodiment of the invention is as follows: when the number of pilot frequency adjacent frequency points under a set network system, which is received by a user terminal and transmitted by a network side device, exceeds the maximum number of pilot frequency adjacent frequency points under the set network system, which is supported and measured by the user terminal, the pilot frequency adjacent frequency points under the set network system, which are transmitted by the network side device, are grouped, so that the number of the pilot frequency adjacent frequency points of each group is less than or equal to the maximum number of the pilot frequency adjacent frequency points under the set network system, which is supported and measured by the user terminal, and then the user terminal respectively measures the pilot frequency adjacent frequency points of each group.
In the embodiment of the invention, the user terminal can respectively measure each group of pilot frequency adjacent frequency points under the set network system, so that the user terminal does not need to discard pilot frequency adjacent frequency points exceeding the self measuring capability range, and the occurrence of the condition of interoperation failure caused by discarding pilot frequency adjacent frequency points meeting the interoperation condition is avoided.
The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
As shown in fig. 1, a flowchart of an inter-frequency measurement method according to an embodiment of the present invention includes the following steps:
s101: and the user terminal receives the pilot frequency adjacent frequency point under the set network system sent by the network side equipment.
Here, different network systems correspond to different Radio Access Technologies (RATs).
In this step, the network equipment configures and issues measurable pilot frequency neighboring frequency points for the user terminal, and the pilot frequency neighboring frequency points can be specifically issued in the measurement configuration information configured by the network side equipment. The network side device may specifically be a Base Station, which may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, or an evolved Node B (eNB) in LTE, and is not limited in the embodiment of the present invention.
S102: when the number of the pilot frequency adjacent frequency points issued by the network side equipment exceeds the maximum number of the pilot frequency adjacent frequency points under the set network system which is supported and measured by the user terminal, the user terminal groups the pilot frequency adjacent frequency points issued by the network side equipment; and the number of the pilot frequency adjacent cell frequency points in each group is less than or equal to the maximum number of the pilot frequency adjacent cell frequency points in the set network system supported and measured by the user terminal.
In this step, the user terminal compares the number of pilot frequency adjacent frequency points in a set network system issued by the network side device with the maximum number of pilot frequency adjacent frequency points in the set network system that can be supported by the user terminal, and if the number of pilot frequency adjacent frequency points in the set network system issued by the network side device is greater than the maximum number of pilot frequency adjacent frequency points in the set network system that can be supported by the user terminal, the pilot frequency adjacent frequency points issued by the network side device are divided into multiple groups, so that the number of pilot frequency adjacent frequency points in each group does not exceed the maximum number of pilot frequency adjacent frequency points in the set network system that the user terminal supports to measure. For example, the number of TD-SCDMA pilot frequency neighboring frequency points issued by the network side device is 9, and the maximum number of TD-SCDMA pilot frequency neighboring frequency points supported and measured by the user terminal is 3, then the user terminal can divide the TD-SCDMA pilot frequency neighboring frequency points issued by the network side device into three groups, where each group includes 3 TD-SCDMA pilot frequency neighboring frequency points.
In the specific implementation process, when the pilot frequency adjacent cell frequency points issued by the network side equipment are grouped, the grouping number can be determinedA group of one or more of the group, wherein,meaning rounded up, i.e. the smallest integer greater than or equal to W/P; w is the number of pilot frequency adjacent frequency points issued by the network side equipment, and P is the maximum number of pilot frequency adjacent frequency points under the set network system which is supported and measured by the user terminal.
In practical implementation, the network side device issuesThe number of adjacent frequency points in the set network system is not necessarily integral multiple of the maximum number of pilot frequency adjacent frequency points in the set network system which is supported and measured by the user terminal. For example, in the above formula for determining the number of packets, when W is 17 and P is 8, the number of packets is determinedBased on this, in a specific implementation, the number of the frequency points of each group of the different-frequency neighboring cells can be determined in the following two ways.
Firstly, the number S of the frequency points of each group of different-frequency adjacent regions in the M-1 group before and after groupingM-1P, the number S of pilot frequency adjacent frequency points in the Mth groupM＝W-SM-1(M-1)。
In this way, for the set network system, after the pilot frequency neighboring frequency points issued by the network side device are grouped according to the above formula, except for the last group, the number of the pilot frequency neighboring frequency points in each group is the maximum number of the pilot frequency neighboring frequency points under the set network system supported by the user terminal, and the number of the pilot frequency neighboring frequency points in the last group is the number remaining after subtracting the number of the pilot frequency neighboring frequency points in the previous groups from the number of the pilot frequency neighboring frequency points issued by the network side device. For example, when W is 17, P is 8, and the number of packets M is 3, the number of inter-frequency neighboring frequency points in each group after grouping in this way is sequentially 8, and 1.
Second, the number of the frequency points of each group of different-frequency adjacent regions in the M-1 group before and after groupingNumber S of pilot frequency adjacent frequency points in Mth groupM＝W-SM-1(M-1)。
This approach uses an averaging concept. Specifically, for a set network standard, after the pilot frequency neighboring frequency points issued by the network side device are grouped according to the above formula, except for the last group, the number of the pilot frequency neighboring frequency points in each group is an integer obtained by dividing the number of the pilot frequency neighboring frequency points issued by the network side device by the number of the groups, and the number of the pilot frequency neighboring frequency points in the last group is the number remaining after subtracting the number of the pilot frequency neighboring frequency points in the previous groups from the number of the pilot frequency neighboring frequency points issued by the network side device. For example, when W is 17, P is 8, and the number of groups M is 3, the number of inter-frequency neighboring frequency points in each group after grouping in this way is 6, and 5 in sequence.
S103: and the user terminal respectively measures each group of pilot frequency adjacent frequency points under the set network system.
In this step, after grouping the pilot frequency neighboring frequency points issued by the network side device according to the issued measurement sequence, the user terminal can simultaneously measure the pilot frequency neighboring frequency points in each group, and report the measurement result meeting the reporting condition (or called neighboring interoperation condition) after measurement to the network side device; here, the measurement result meeting the reporting condition may include signal quality information of an inter-frequency neighboring frequency point when the neighboring cell signal quality is greater than a set threshold, and may also include signal quality information of the cell when the cell signal quality is lower than the set threshold.
In a specific implementation process, after a group of pilot frequency adjacent frequency points are measured, the user terminal can report the measurement result meeting the reporting condition in the group of measurements to the network side equipment, and if the user terminal determines that no measurement result meeting the reporting condition in the group of measurements is obtained after the user terminal finishes measuring the group of pilot frequency adjacent frequency points, the measurement of the next group of frequency points is continued; the network side device may determine a target frequency point at which the user terminal performs neighbor cell interoperation when receiving a measurement report of a first group of pilot frequency neighbor cell frequency points reported by the user terminal, and trigger the user terminal to perform neighbor cell interoperation in a system or between systems, where the neighbor cell interoperation includes cell redirection, cell reselection, and cell handover, for example, trigger the user terminal to perform redirection from an LTE cell to a 3G cell. The network side equipment can also start a timer after receiving a first measurement report reported by the user terminal, and determine a target frequency point for the user terminal to execute the neighbor cell interoperation if the timer is overtime and the measurement report of the user terminal about other neighbor cell frequency points is not received; if the measurement reports of the user terminal about other adjacent frequency points are received before the timer is overtime, all the measurement reports reported by the user terminal before are merged, the optimal target frequency point is determined, and the user terminal is instructed to execute adjacent interoperation aiming at the target frequency point.
The user terminal can also report the measurement result meeting the reporting condition to the network side equipment after all the groups of pilot frequency adjacent frequency points are measured; after receiving the measurement report reported by the user terminal, the network side equipment selects the optimal target frequency point from the measurement report, and instructs the user terminal to execute the neighboring cell interoperation aiming at the target frequency point.
Preferably, in the above step, after receiving the pilot frequency neighboring cell frequency point in the set network format issued by the network side device, before grouping the pilot frequency neighboring cell frequency points issued by the network side device, the method further includes:
deleting frequency points which are not in the physical frequency point range corresponding to the frequency band supported by the user from the pilot frequency adjacent frequency points; and/or the presence of a gas in the gas,
and deleting the frequency points which can not search the signals from the pilot frequency adjacent frequency points.
In a specific implementation process, before performing neighbor cell measurement, a user terminal may perform preliminary screening on pilot frequency neighbor frequency points issued by a network side device, for example, delete a frequency point that is not supported by the user terminal (i.e., a frequency point that is not within a physical frequency point range corresponding to a frequency band supported by the user terminal) and/or a neighbor frequency point that cannot detect a signal from the pilot frequency neighbor frequency points, after performing the preliminary screening, compare the number of pilot frequency points in each remaining network system with the maximum number of pilot frequency points in the network system that supports measurement by the user terminal, and perform grouping processing if the number of pilot frequency points in the remaining network system is still greater than the maximum number of pilot frequency points in the network system that supports measurement by the user terminal.
In the above embodiment, the frequency points in the physical frequency point range corresponding to the frequency Band (Band) supported by the user terminal include not only the frequency points whose frequency point numbers are in the frequency point number range of the frequency Band supported by the user terminal, but also the frequency points whose frequency point numbers are not in the frequency point number range of the frequency Band supported by the user terminal, but the physical frequency points corresponding to the frequency point numbers are in the physical frequency point range corresponding to the frequency Band supported by the user terminal. For example, there are two frequency bands, which are Band38 and Band41, respectively, where the frequency range of Band38 is 2570 MHz (abbreviated as MHz) to 2620MHz, corresponding to the frequency point numbers 37750 to 38249, the frequency range of Band41 is 2496MHz to 2690MHz, and corresponding to the frequency point numbers 39650 to 41589. It can be seen that frequency point numbers of Band38 and Band41 are different, but physical frequency point ranges of the two overlap. If the frequency Band supported by the user terminal is Band41 and does not support Band38, but the frequency point number of the neighboring cell sent by the network side equipment is frequency point number 37950 of Band38, the frequency point number is not in the frequency point number range of Band41 supported by the user terminal, but the physical frequency point 2590MHz corresponding to the frequency point number is in the physical frequency point range of 2496 MHz-2690 MHz supported by the user terminal, so the user terminal can measure the frequency point.
The invention is further illustrated by the following example.
As shown in fig. 2, a flowchart of an inter-frequency measurement method according to a second embodiment of the present invention includes the following steps:
s201: and the network side equipment transmits the pilot frequency adjacent frequency points to be measured under each network type to the user terminal.
In practical implementation, the pilot frequency adjacent frequency points issued by the network side equipment may be of multiple network systems; the user terminal needs to perform the following operations according to the maximum number of pilot frequency adjacent frequency points in each network system supporting measurement.
S202: after receiving pilot frequency adjacent frequency points in a set network system sent by network side equipment, a user terminal deletes frequency points which are not in a physical frequency point range corresponding to a frequency band supported by the user terminal from the pilot frequency adjacent frequency points and searches frequency points of signals which cannot be found by the user terminal.
S203: for any network system, the user terminal determines whether the number of pilot frequency neighboring cells in the network system remaining after S202 is greater than the maximum number of pilot frequency neighboring cells in the network system that the user terminal supports measurement, if so, the step S205 is performed, otherwise, the step S204 is performed.
S204: and the user terminal measures the pilot frequency adjacent frequency points under the rest network system.
S205: the user terminal groups the rest pilot frequency adjacent frequency points; wherein the number of packetsThe number of the groups is set to be,indicating to round up, wherein W is the number of the residual pilot frequency adjacent cell frequency points, and P is the maximum number of pilot frequency adjacent cell frequency points under the set network system which is supported and measured by the user terminal; wherein, the number S of the frequency points of each group of the different-frequency adjacent regions in the M-1 group before groupingM-1P orNumber S of pilot frequency adjacent frequency points in Mth groupM＝W-SM-1(M-1)。
S206: and the user terminal respectively measures each group of pilot frequency adjacent frequency points.
Here, when the pilot frequency neighboring frequency points issued by the network side device are in multiple network systems, after the pilot frequency neighboring frequency points in the multiple network systems are respectively grouped, each group of pilot frequency neighboring frequency points in different network systems can be measured in a combined manner. For example, if the pilot frequency neighboring frequency points in the network system 1 are divided into 3 groups, and the pilot frequency neighboring frequency points in the network system 2 are divided into 2 groups, the first group of pilot frequency neighboring frequency points in the network system 1 and the first group of pilot frequency neighboring frequency points in the network system 2 may be combined into one group for measurement, the second group of pilot frequency neighboring frequency points in the network system 1 and the second group of pilot frequency neighboring frequency points in the network system 2 may be combined into one group for measurement, and the third group of pilot frequency neighboring frequency points in the network system 1 may be measured separately.
S207: after the user terminal finishes measuring a group of pilot frequency adjacent frequency points, reporting the measurement result meeting the reporting condition to the network side equipment; or after all the groups of pilot frequency adjacent frequency points are measured, reporting the measurement result meeting the reporting condition to the network side equipment.
Based on the same inventive concept, the embodiment of the present invention further provides a pilot frequency measurement apparatus corresponding to the pilot frequency measurement method, and because the principle of the apparatus for solving the problem is similar to the pilot frequency measurement method in the embodiment of the present invention, the implementation of the apparatus can refer to the implementation of the method, and repeated details are not repeated.
