Description

Method and terminal for performing neighbor cell measurement by the terminal The application is submitted to the Chinese Patent Office on August 15, 2006, and the application number is 200610111215.6, and the invention name is "the method and terminal for the terminal to perform adjacent d and area measurement in the long term evolution system". Priority of Chinese Patent Application, the entire contents of which is incorporated herein by reference. Technical field

The present invention relates to the field of communications, and in particular, to a technology for a terminal to perform neighbor cell measurement. Background technique

In the Wideband Code Division Multiple Access (WCDMA) communication system, the same-frequency neighboring cell means that the carrier frequency of the neighboring cell is the same as the carrier frequency of the serving cell, and the terminal (UE) can receive the target cell without adjusting the receiver frequency. Common channel information, the inter-frequency neighboring cell means that the carrier frequency of the neighboring cell is different from the carrier frequency of the serving cell.

In the WCDMA communication system, the method for the terminal UE to measure the neighboring cell is: al: the network side sends the system message or the dedicated measurement control message, and the sent message includes the intra-frequency neighbor cell or the inter-frequency neighbor cell information; a2: The terminal performs corresponding intra-frequency neighbor cell measurement or inter-frequency neighbor cell measurement according to the intra-frequency neighbor cell information or the inter-frequency neighbor cell information delivered by the network side, so that the cell reselection can be determined according to the neighbor cell information measured by the terminal UE. Cell handover.

With the continued development of 3G (third generation) mobile communication systems, Long Term Evolution (LTE) systems have been proposed and deployed in 3GPP. LTE has developed rapidly due to its advantages of higher user data rates, increased system capacity and coverage, and reasonable and flexible 3G spectrum allocation. In the LTE system, the neighboring cells are classified into two types: one neighboring cell with the same frequency as the serving cell is a neighboring cell in the same layer. For the sake of specification, it is called the same-frequency neighboring cell, and the other is the neighboring frequency of the serving cell. A cell is a heterogeneous neighboring cell, which is called an inter-frequency neighboring cell.

Currently, in the LTE system, the terminal UE does not have a neighbor cell measurement scheme related to the intra-frequency neighboring cell and the inter-frequency neighboring cell, thereby causing no neighbor cell measurement for the LTE system, which is disadvantageous for the long-term development of the entire LTE system.

The present invention will be described in detail below with reference to the accompanying drawings.

The method provided by the embodiment of the present invention is based on the LTE broadband wireless mobile communication system as shown in FIG. 1. In Figure 1, an Access Service Gateway (ASGW) indicates an access service gateway entity of a broadband wireless mobile communication system, which is used to complete the access of users in the system and the routing and forwarding of signaling and services within the system. The eNodeB represents a new type of Node B logical node, which is used to complete the air interface physical layer and some high-level protocols, and is the node that the mobile terminal accesses for the first time when accessing the system. The RRM Server (Radio Resource Management Server) in the figure is an optional functional entity, which is mainly used to assist in the process of radio resource management between cells in a broadband wireless mobile communication system. It may also be a multi-cell mobility management. The process provides a data source. The XI interface indicates the connection relationship between the eNodeBs in the broadband wireless mobile communication system, and is the channel for controlling the plane signaling transmission between the eNodeBs, and is the internal interface in the radio access network. The S1 interface is an interface between the radio access network and its superior node in the broadband wireless mobile communication system, and is used to provide a transmission link between the control plane and the user plane. The 01 interface shown in the figure is an optional interface. When E-UTRAN deploys the optional functional entity of RRM Server, the eNodeB needs to connect to the RRM Server by installing the 01 interface. Generally, the UE sends the UE message to the UE in the LTE system, and the ASGW and the eNodeB send the message to the UE.

Please refer to FIG. 2, which is a flowchart of a method for a neighbor to perform neighbor cell measurement in an LTE system according to the present invention. The method includes:

S110: The terminal receives the measurement control message sent by the network side.

The network side sends a measurement control message, and the measurement control message may be a system message or a dedicated measurement control message. Here, the dedicated measurement control message refers to a measurement control message sent by the network side to the terminal when the terminal is in the connected state. The measurement control message includes a measurement manner indicated by the network side to the neighboring cell, and may also carry neighbor cell information. The measurement method of the neighboring cell is the same frequency measurement or the inter-frequency measurement. The neighbor cell information may include the type of the neighboring cell, that is, the neighboring cell is a terminal service. The same-frequency neighboring cell or inter-frequency neighboring cell of the cell; or/and information required to receive a message of a common channel (such as a BCH channel) of the neighboring cell, such as frequency point information. When the specified measurement mode is inter-frequency measurement, the measurement control message may further include information of a measurement gap for the measurement gap that the terminal can specify to perform inter-frequency neighboring d-area measurement.

S120: The terminal performs co-frequency measurement or inter-frequency measurement on the neighboring cell according to the measurement mode specified in the measurement control message.

If the type of the neighboring cell in the received measurement control message is not distinguished, that is, the neighboring cell is not classified into the same-frequency neighboring cell or the inter-frequency neighboring cell or performs other classification, the terminal determines that the neighboring cell belongs to the terminal. The co-frequency neighboring cell of the serving cell is also an inter-frequency neighbor cell.

The terminal performs measurement on the neighboring cell according to the measurement mode specified in the measurement control message. The specific measurement process is described below.

A. The measurement of the same-frequency neighboring cell by the terminal is the same-frequency measurement, and the measurement of the inter-frequency neighboring cell may be the same-frequency measurement or the inter-frequency measurement.

When the measurement mode indicated by the network side is the same frequency measurement, the terminal measures the same frequency neighboring cell as the same frequency measurement, and if the terminal can receive the inter-frequency neighboring cell common channel message without adjusting the frequency, the terminal The inter-frequency neighboring cell also performs the same frequency measurement.

When receiving the measurement mode indicated by the network side as the inter-frequency measurement, the terminal performs the inter-frequency measurement on the inter-frequency neighboring cell.

The measurement of the same-frequency neighboring cell by the terminal is the same-frequency measurement; the terminal determines to perform the same-frequency measurement or the inter-frequency measurement on the inter-frequency neighboring cell according to the situation of the inter-frequency neighboring cell. As shown in FIG. 3 and FIG. 4, Cell2 is a co-frequency cell of Celll, and UE1 and UE2 measure Cell2 as an intra-frequency measurement. Cell3 is an inter-frequency cell of Celll. The frequency band in which the cell 3 of the neighboring cell is located falls within the range of the frequency band in which the UE1 is located. In other words, the center frequency of the cell 3 of the neighboring cell falls within the frequency range of the UE1, which means that the UE1 does not need to adjust the locality. The terminal receiver frequency can receive the _ce 113 common channel (such as BCH channel) message, and the UE1 measurement of Cell3 is the same frequency measurement. If the UE needs to adjust the local receiver frequency to receive the common channel message of the neighboring cell, the terminal performs the inter-frequency measurement on the inter-frequency neighboring cell. For example, UE2's measurement of Cell3 is an inter-frequency measurement. In Figure 3, the bandwidth of UE1 and UE2 is 10.625MHz, and the SCH channel is located in the middle of the transmission bandwidth, and there is only one. In this case, it can be judged whether the terminal can perform the same-frequency measurement on the inter-frequency neighboring cell. In Figure 4, the bandwidth of UE1 and UE2 is 10MHz. When the cell transmission bandwidth is 20 MHz, one cell has two SCH channels. In the case of FIG. 4, it can be determined whether the terminal can perform the same-frequency measurement on the inter-frequency neighboring cell according to whether the frequency band in which the neighboring cell is located falls within the range of the frequency band in which the terminal is located.

Referring to FIG. 5, Cell2 and Cell4 are the same-frequency cells of Cell1, and UE1 and UE2 measure the same frequency for Cell2 and Cell4; Cell3 is an inter-frequency cell of Celll. The frequency band in which the cell 3 of the neighboring cell is located falls within the range of the frequency band in which the UE1 is located. In other words, the center frequency of the cell 3 of the neighboring cell falls within the frequency range of the UE1, which means that the UE1 can receive the cell3 without adjusting the frequency of the local receiver. Common channel (such as BCH channel) message, UE1's measurement of Cell3 is the same frequency measurement. If the UE needs to adjust the local receiver frequency to receive the common channel message of the neighboring cell, the UE performs the inter-frequency measurement on the inter-frequency neighboring cell. For example, UE2's measurement of Cell3 is an inter-frequency measurement.

In summary, when the terminal UE receives the message:

If the network side indicates that the intra-frequency measurement is performed and the intra-frequency neighbor cell information or/and the inter-frequency neighbor cell information is delivered, the terminal UE performs the same-frequency measurement on the same-frequency neighboring cell; the terminal UE receives the inter-frequency according to whether the frequency needs to be adjusted. The common channel message of the neighboring cell determines whether the measurement mode of the inter-frequency neighboring cell can be the same-frequency measurement. If the frequency is not required to be adjusted, the same-frequency measurement can be performed.

If the network side indicates that the inter-frequency measurement is performed and the inter-frequency neighbor cell information is delivered, the terminal UE performs the inter-frequency measurement.

The terminal performs inter-frequency measurement in the indicated measurement gap, where the measurement gap is indicated in the measurement control message, or the network side indicates in the scheduling information of the time domain and/or the frequency domain resource allocated to the terminal.

In addition, the terminal can perform inter-frequency measurement at a predetermined inter-frequency measurement time. The terminal may also perform the inter-frequency measurement when detecting that the current idle resource satisfies the condition for performing the inter-frequency measurement. The minimum conditions that can be used for inter-frequency measurements include the minimum time/time domain resources required for inter-frequency measurements.

As can be seen from the above, the timing of the inter-frequency measurement by the terminal may be set by the network side, may be preset, or may be determined according to the specific resources of the terminal.

B. Perform intra-frequency measurement on the same-frequency neighboring cell, and perform inter-frequency measurement on the inter-frequency neighboring cell. If the network side indication is received to perform the same-frequency measurement and the intra-frequency neighbor cell information, the terminal performs the same-frequency measurement on the same-frequency neighboring cell; if the network-side indication is received to perform the inter-frequency measurement and the inter-frequency neighbor cell information, the terminal is The inter-frequency neighboring cell performs inter-frequency measurement.

If the network side indicates that the inter-frequency measurement is performed and the inter-frequency neighbor cell information is delivered, the UE performs the inter-frequency measurement.

In addition, the terminal performs inter-frequency measurement at a preset inter-frequency measurement time. The terminal may also perform the inter-frequency measurement when detecting that the current idle resource satisfies the condition for performing the inter-frequency measurement. The conditions for performing the inter-frequency measurement include the minimum time/time domain resources required for the inter-frequency measurement.

As shown in Figure 6, Cell2 is the same-frequency cell of Cell1, UE1 and UE2 measure the same frequency for Cell2; Cell3 is the inter-frequency cell of Celll, and UE1 and UE2 measure the inter-frequency of Cell3.

Please refer to FIG. 7, which is a schematic structural diagram of a terminal according to the present invention. It includes: the same frequency measurement unit: When the measurement mode of the indication received by the network side is the same frequency measurement, the measurement of the same frequency neighboring cell is the same frequency measurement, and if the terminal does not adjust the frequency of the local receiver, it can receive the inter-frequency neighboring cell.

In the foregoing embodiment, the terminal performs on-frequency measurement or inter-frequency measurement on the neighboring cell according to a measurement manner specified by the network side. In addition, the terminal may also decide to use the same frequency for the neighboring cell. The measurement is also an inter-frequency measurement.

Please refer to FIG. 8, which is another method for a terminal to perform neighbor cell measurement in a long term evolution system according to the present invention. it includes:

S210: The terminal receives the measurement control message sent by the network side. The neighboring cell information may be included in the measurement control message. However, the measurement control message may not include the measurement mode specified for the neighboring cell.

The measurement control message on the network side of the present invention does not include the measurement mode of the neighboring cell. In this case, the terminal needs to determine the measurement mode of the neighboring cell for the neighbor cell measurement. In addition, the measurement control message sent by the network side may include the type of the neighboring cell, or may not include the type of the neighboring cell. When the type of the neighboring cell is not included in the measurement control message, the terminal may determine the type of the neighboring cell to be measured, that is, if the neighboring cell in the received measurement control message is not distinguished, that is, the neighboring cell is not divided. The same-frequency neighboring cell or the inter-frequency neighboring cell or other classification, the terminal needs to determine whether the neighboring cell belongs to the same-frequency neighboring cell or the inter-frequency neighboring cell of the serving cell of the terminal. For example, when the neighboring cell information in the measurement control message includes the frequency band in which the neighboring cell is located, the terminal may compare the frequency band with the frequency band in which the serving cell of the terminal is located, or the center frequency of the neighboring cell and the serving cell of the local terminal. After comparing the center frequencies, it is determined whether the neighboring cell belongs to the same-frequency neighboring cell or the inter-frequency neighboring cell of the serving cell.

S220: The terminal measures the neighboring cell according to a self-determined measurement manner of the neighboring cell.

A. The measurement of the same-frequency neighboring cell by the terminal is the same-frequency measurement. If the common-channel neighboring cell common channel message can be received without adjusting the local-end receiver frequency, the terminal performs the same-frequency measurement on the inter-frequency neighboring cell. Otherwise, , Perform inter-frequency measurement.

The terminal performs an inter-frequency measurement in the indicated measurement gap, where the measurement gap is indicated by the measurement control message, or the network side allocates the scheduling information in the time domain and/or the frequency domain resource allocation scheduling information to the terminal. .

B. The measurement of the same-frequency neighboring cell by the terminal is the same-frequency measurement, and the inter-frequency neighboring cell is used for the inter-frequency measurement. Measurement.

In addition, the terminal performs inter-frequency measurement at a preset inter-frequency measurement time. The terminal may also perform the inter-frequency measurement when detecting that the current idle resource satisfies the condition for performing the inter-frequency measurement. The minimum conditions that can be used for inter-frequency measurements include the minimum time/time domain resources required for inter-frequency measurements.

C. If the terminal needs to adjust the frequency of the local receiver to receive the common channel neighboring cell common channel message, the terminal performs the inter-frequency measurement on the same-frequency neighboring cell, otherwise performs the same-frequency measurement on the same-frequency neighboring cell. The terminal can perform inter-frequency measurement on all inter-frequency neighboring cells.

D. If the terminal needs to adjust the frequency of the local receiver to receive the common channel neighboring cell common channel message, the terminal performs the inter-frequency measurement on the same-frequency neighboring cell, otherwise performs the same-frequency measurement on the same-frequency neighboring cell. The terminal can also perform the same-frequency/inter-frequency measurement on the inter-frequency neighboring cell. For example, if it is not necessary to adjust the local receiver frequency to receive the inter-frequency neighbor cell common channel message, the terminal performs the same-frequency measurement on the inter-frequency neighboring cell, and otherwise performs the inter-frequency measurement on the inter-frequency neighboring cell.

In the foregoing method, determining whether the frequency of the local terminal needs to be adjusted to receive the common channel neighboring cell common channel message according to whether the frequency band in which the neighboring cell is located falls within the range of the frequency band in which the terminal is located, and if the frequency band in which the neighboring cell is located falls in the terminal Within the range of the frequency band in which the terminal is located, the terminal may receive the inter-frequency neighbor cell common channel message without adjusting the frequency of the terminal.

S510: The terminal receives a measurement control message that is sent by the network side and includes the cell information. S520: If the terminal does not need to adjust the local receiver frequency to receive the neighbor cell common channel message, the terminal performs intra-frequency measurement on the neighboring cell (S530). Otherwise, the terminal performs inter-frequency measurement on the neighboring cell (S530).

In the above method, in the measurement process of the neighboring cell, the terminal does not need to determine whether the neighboring cell to be measured is a co-frequency neighboring cell or an inter-frequency neighboring cell. The terminal only needs to determine whether it needs to adjust the local receiver frequency to receive the neighbor cell common channel message, and if so, perform the inter-frequency measurement, otherwise perform the same-frequency measurement. The method is simple in design, and the terminal in the LTE system receives the neighbor cell information.

The present invention provides a solution for a terminal to receive a neighboring cell in an LTE system, and solves the problem that there is no relevant measurement method in LTE. Moreover, with the measurement method of the present invention, it is not possible to receive only partial neighbor cell information or to receive neighbor cell information, and the accuracy of reception is improved.
