Method and terminal for cell measurement reselection

This application is submitted to the Chinese Patent Office on February 20, 2012, and the application number is

201210038349.5, the entire disclosure of which is incorporated herein by reference in its entirety in its entirety in its entirety in the the the the the the the the the the the Technical field

The present invention relates to the field of communications technologies, and in particular, to a method and a terminal for cell measurement reselection. Background technique

Due to the needs of network deployment and business operations, cells supporting multiple multi-radio access technologies (multi-RAT, multi-radio access technology) will be deployed in the same or adjacent areas. At the same time, a lot of support has emerged in the market. Two or more radio access technology terminals, such as GU (GSM-UMTS, Global System for Mobile communications-Universal Mobile Telecommunications System) dual-mode terminal, GL (GSM-LTE, GSM-Long Term Enhanced) dual-mode terminal, etc. . In order to perform measurement, selection/reselection on a cell supporting the same or different access technologies (inter-RAT), the multi-RAT terminal is required to acquire information of the inter-RAT cell adjacent to the current camping/serving cell, In order to obtain information about these inter-RAT neighbors, zones, and measurement reselection, the multi-RAT-enabled terminal needs to read the system messages of the camped/serving cells because these system messages contain relevant parameters for measurement reselection. . However, these system messages are often sent in multiple messages and are not synchronized. In some cases, the reselection fails because the measurement reselection information is incomplete.

For example, in the prior art, the measurement reselection related information of the global terrestrial radio access network (UTRAN) is not only sent in the system message SI2quater message, but also in the system message SI2ter message. The frequency information of the UTRAN is composed of the UTRAN frequency information carried in the SI2quater message and the SI2ter message, and the UTRAN frequency point information corresponds to the measurement reselection parameter of the UTRAN.

However, since the SI2quater message and the SI2ter message are sent periodically, and there may be multiple instances (ie, message segmentation) in the SI2quater message and the SI2ter message, they are not delivered at the same time. Therefore, in some scenarios, the measurement reselection parameter and the frequency point information reception are not synchronized, and the terminal cannot find the corresponding UTRAN frequency point information through the access network measurement reselection parameter. Cell measurement and reselection are performed on these UTRAN frequencies. Summary of the invention

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. The details are described below separately.

Referring to FIG. 1 , FIG. 1 is a flowchart of a method for cell measurement reselection according to an embodiment of the present invention, where the method includes:

511. Receive a first system message, where the number of the first system message includes one or more;

It can be understood that the executive body can be a terminal, specifically a terminal supporting a Universal Mobile Telecommunications System (UMTS).

A first system message is a message segment (instance).

512. Store an access network measurement reselection parameter in the first system message.

Taking the access network as the global terrestrial radio access network UTRAN network as an example, the method for cell measurement reselection provided by the embodiment of the present invention can be applied to measurement reselection in a UTRAN macro cell, and can also be applied to a closed user group CSG in UTRAN ( Closed Subscriber Group) The measurement reselection of the cell; correspondingly, the access network measurement reselection parameter may be a measurement reselection parameter of the UTRAN macro cell, including: a UTRAN frequency index value, a priority information of the UTRAN cell, and a UTRAN cell The reselection threshold parameter; the access network measurement reselection parameter may also be a measurement reselection parameter of the CSG cell in the UTRAN, including: a CSG cell frequency point index value and a CSG cell physical scrambling code (PSC).

The UTRAN cell mentioned in the embodiment of the present invention refers to a UTRAN macro cell.

Further, the priority information of the UTRAN cell includes a default UTRAN cell priority and a priority of the UTRAN cell frequency point; the reselection threshold parameter of the UTRAN cell includes a default UTRAN 'J, a region threshold, a default UTRAN cell minimum reception level, and a UTRAN The cell frequency high threshold, the UTRAN cell frequency low threshold, and the UTRAN cell minimum reception level.

Taking the access network as the UTRAN as an example, the access network frequency point information mentioned in the embodiment of the present invention is UTRAN frequency point information, specifically referring to the frequency of the UTRAN frequency point.

If the access network measurement reselection parameter is a measurement reselection parameter of the UTRAN cell, the UTRAN frequency point index value in the measurement reselection parameter of the UTRAN cell and the UTRAN frequency point information correspond to each other, and when the specific UTRAN frequency point information is learned, Other UTRAN related information (such as priority information of the UTRAN cell and reselection threshold parameter of the UTRAN cell) may be obtained according to the corresponding UTRAN frequency point index value.

514. Perform cell measurement and reselection according to the access network frequency point information and the saved access network measurement reselection parameters. According to the above, a method for cell reselection according to an embodiment of the present invention is provided. The method receives a first system message, and performs an action of saving an access network measurement reselection parameter in the first system message; When the access network measures the frequency information of the access network corresponding to the reselection parameter, the access network frequency point information can be found according to the saved access network measurement reselection parameter, so that the cell measurement reselection can be performed normally.

In an embodiment of the present invention, the terminal receives the first system message, and the number of received first system messages includes one or more. After receiving the first system message, the second system message may also be received, and the received second system is received. The number of messages includes more than one; at this time, the access network measurement reselection parameter in the first system message is saved until at least all the second system messages are received, that is, before the second system message is received, it needs to be saved all the time. The access network in the first system message measures the reselection parameter; and receives the access network frequency point information corresponding to the access network measurement reselection parameter. It can be understood that the access network frequency point information may be the first system. The message is delivered, or may be sent by the second system message. Finally, the cell measurement and reselection are performed according to the access network frequency point information and the saved access network measurement reselection parameter.

The process of receiving the frequency information of the access network corresponding to the measurement reselection parameter of the access network, and triggering the process of cell measurement and reselection, specifically performing the following two application scenarios for analysis and analysis:

In an application scenario, the receiving access network frequency information corresponding to the access network measurement reselection parameter may be specifically: receiving the access network frequency corresponding to the access network measurement reselection parameter carried in the first system message Point information, and access network frequency point information corresponding to the access network measurement reselection parameter carried in the second system message; thereafter, performing cell according to the access network frequency point information and the saved access network measurement reselection parameter The measurement and reselection may be specifically: determining, when receiving the access network frequency point information corresponding to the access network measurement reselection parameter carried in the first system message and the second system message, according to the first system message and the The measurement and reselection of the cell is performed by the access network frequency point information corresponding to the access network measurement reselection parameter and the saved access network measurement reselection parameter carried in the second system message.

It can be understood that the application scenario indicates that the terminal needs to receive the first system message and the second system; the access network frequency point information corresponding to the access network measurement reselection parameter is received, and the priority-based implementation is performed. Cell measurement and reselection actions.

In another application scenario, the receiving the access network frequency point information corresponding to the access network measurement reselection parameter may be specifically: receiving the access network corresponding to the access network measurement reselection parameter carried in the first system message Frequency point information; thereafter, the cell measurement and reselection according to the access network frequency point information and the saved access network measurement reselection parameter may be specifically: determining and carrying the received and received in the first system message When the access network measures the access network frequency point information corresponding to the reselection parameter, the reselection parameter is measured according to the frequency of the access network frequency point corresponding to the access network measurement reselection parameter carried in the first system message and the saved access network. Perform cell measurement and reselection.

It can be understood that the application scenario indicates that the terminal performs the measurement based on the priority-based cell only after determining that the access network frequency point information corresponding to the access network measurement reselection parameter carried in the first system message has been received. The action of reselection, at this time, may not have received the second system message, or has not received all the second system messages.

In some implementation manners of the application scenario, the first system message received by the terminal carries the access network frequency point information corresponding to all the measurement reselection parameters.

When the cell measurement reselection method provided by the embodiment of the present invention can be applied to the measurement reselection of the UTRAN macro cell of the global terrestrial radio access network, the terminal determines, after receiving the first system message, corresponding to the access network measurement reselection parameter. The step of accessing the network frequency point information may be specifically: the terminal determines, according to the UTRAN measurement reselection parameter start and/or end indication bit in the first system message, the reselection of the measurement and the access network carried in the first system message. The access network UTRAN frequency point information corresponding to the parameter; after the terminal receives the complete second system message, determining, by the terminal, the access network frequency point information corresponding to the access network measurement reselection parameter carried in the second system message.

It should be noted that the UTRAN measurement reselection parameter start and/or end indication bit is used to indicate whether the UTRAN measurement reselection parameter in the first system message is received. In practice, the UTRAN measurement reselection parameter receives the UTRAN frequency point information. The reception is also completed. Therefore, after the UTRAN measurement reselection parameter start and/or end indication bit is determined to be received according to the UTRAN measurement reselection parameter start and/or end indication bits, the UTRAN frequency point information reception may be considered complete.

In another embodiment of the present invention, the method for providing cell measurement reselection may be used for measurement reselection of a CSG cell in UTRAN, and the access network measurement reselection parameter in the first system message may be a measurement of a CSG cell. Reselection parameters, including CSG cell frequency point index value and CSG cell physical scrambling code information;

After receiving the first system message, the terminal determines to receive the access network frequency information corresponding to the access network measurement reselection parameter carried in the first system message.

It can be understood that, in the foregoing embodiment, the first system message may be an SI2quater message or other system message that carries an access network measurement reselection parameter, and the second system message may be an SI2ter message or other access network frequency point information. Other system messages.

It can be seen from the above that a method for cell measurement reselection provided by an embodiment of the present invention is provided. Receiving the first system message and saving the access network measurement reselection parameter in the first system message; receiving the access network frequency point information corresponding to the access network measurement reselection parameter, if the received access network frequency point is received When the information is sent by the second system message, the corresponding access network frequency point information can still be found according to the saved access network measurement reselection parameter, so that the cell measurement reselection can be performed normally.

For the sake of understanding, the following embodiments describe the method provided by the embodiment of the present invention in a specific application scenario. In this application scenario, the execution subject is a terminal, the first system message is an SI2quater message, and the second system message is SI2ter. The message, the access network is the global terrestrial radio access network UTRAN.

Referring to FIG. 2, FIG. 2 is a flowchart of a cell measurement reselection method according to an embodiment of the present invention, where the method includes:

521. The terminal receives the SI2quater message.

522. The terminal receives the SI2ter message.

It can be understood that the terminal supports a universal mobile communication system; wherein the number of SI2quater messages received by the terminal includes more than one, and the number of received SI2ter messages includes more than one.

S23. The terminal saves the global terrestrial radio access network in the SI2quater message. The UTRAN measurement reselection parameter is received at least until all SI2ter messages are received.

When the terminal receives the SI2quater message, it is also necessary to save the UTRAN measurement reselection parameter in the SI2quater message, so step S23 can also be performed before step S22 or simultaneously with step S22.

Preferably, in this embodiment, the UTRAN measurement reselection parameter included in the system message SI2quater may include the UTRAN measurement reselection parameter including the UTRAN frequency point index value, the priority information of the UTRAN cell, and the reselection threshold parameter of the UTRAN cell. .

The priority information of the UTRAN cell and the reselection threshold parameter of the UTRAN cell indicate specific UTRAN frequency point information according to the UTRAN frequency point index value.

It can be understood that, in some embodiments, the UTRAN measurement reselection parameter included in the SI2quater message may be a measurement reselection parameter of the closed subscriber group CSG cell, where the measurement reselection parameter of the CSG cell includes the CSG cell frequency index. Value and CSG cell physical scrambling code information.

The CSG cell refers to a CSG cell in a UTRAN cell, and the UTRAN cell refers to a UTRAN macro cell. The CSG cell is a micro cell, which can be set up in a small area such as a home or an office or a store. The CSG cell can also use the UTRAN access technology.

In the system message SI2ter, only the UTRAN frequency point information and the cell type based on the sorting method are included. For the reselection parameter, there is no corresponding priority parameter and a priority-based reselection threshold. For this embodiment, only UTRAN frequency information in the SI2ter message can be used for measurement and reselection of the priority-based cell.

It can be understood that the UTRAN frequency point information indicated by the UTRAN frequency index value in the UTRAN measurement reselection parameter in the SI2quater message may be the UTRAN frequency point information carried in the SI2quater message, or the UTRAN frequency point carried in the SI2ter message. information.

In step S23, the UTRAN measurement reselection parameter in the SI2quater message is saved, and the UTRAN measurement in the SI2quater message needs to be saved before all the SI2ter messages are received, that is, before the UTRAN frequency information in the complete SI2ter message is received. Reselect the parameters.

524. The terminal receives the UTRAN frequency point information corresponding to the UTRAN measurement reselection parameter carried in the SI2quater message, and the UTRAN frequency point information corresponding to the UTRAN measurement reselection parameter carried in the SI2ter message.

525. When determining, by the terminal, the UTRAN frequency point information corresponding to the UTRAN measurement reselection parameter in the SI2quater message and the SI2ter message, according to the UTRAN frequency point information and the saved UTRAN measurement corresponding to the UTRAN measurement reselection parameter in the SI2quater message and the SI2ter message. Reselecting parameters for cell measurement and reselection;

The system message SI2quater message and the SI2ter message are periodically delivered. There may be multiple instances in the SI2quater message and the SI2ter message, and the system message is not sent at the same time. An instance of the system message refers to a message segment of the system message. .

In this embodiment, the terminal receives the access network frequency point information corresponding to the access network measurement reselection parameter in the SI2quater message and the SI2ter message, and performs the measurement and reselection action of the priority based cell; When all the access network frequency point information terminals corresponding to the measurement reselection parameters have been received, the cell measurement reselection can be performed at more frequency points.

It can be understood that the terminal can also receive the UTRAN frequency point information corresponding to the UTRAN measurement reselection parameter carried in the SI2quater message, and determine that the UTRAN frequency point information corresponding to the UTRAN measurement reselection parameter carried in the SI2quater message is received, according to The frequency of the UTRAN frequency point corresponding to the UTRAN measurement reselection parameter carried in the first system message and the saved access network measurement reselection parameter perform cell measurement and reselection. In this case, the terminal may perform the measurement and reselection of the priority-based cell as long as it has determined that the UTRAN frequency point information corresponding to the UTRAN measurement reselection parameter carried in the SI2quater message has been received, and the action may be performed at this time. I have not received the SI2ter message yet, or have not received all the SI2ter messages. At this point, there may be a part of the test The access network frequency point information terminal corresponding to the quantity reselection parameter is not received. In one way, the frequency at which the terminal performs measurement reselection of the cell is less.

In step S25, the terminal determines to receive the UTRAN frequency point information corresponding to the UTRAN measurement reselection parameter carried in the SI2quater message, which may be based on the UTRAN measurement reselection parameter start and/or end indication bit in the SI2quater message "UTRAN_Start" /Stop" determines the UTRAN frequency point information corresponding to the UTRAN measurement reselection parameter carried in the SI2quater message; and the terminal determines to receive the UTRAN frequency point information corresponding to the UTRAN measurement reselection parameter carried in the SI2ter message, and needs to receive The full SI2ter message, because there is no indication in the SI2ter message that the UTRAN measurement reselection parameter starts and/or ends in the SI2quater message.

The terminal determines the UTRAN frequency point information corresponding to the UTRAN measurement reselection parameter carried in the SI2quater message, and determines whether it has been collected according to "UTRAN_Start/Stop".

The UTRAN measurement reselection parameters in the SI2quater message, including the UTRAN frequency point index value, the priority information of the UTRAN cell, and the reselection threshold parameter of the UTRAN cell, can be expressed as follows:

< 3G Priority Parameters Description struct > ::=

< UTRAN— Start: bit >

< UTRAN— Stop: bit >

{ 0 I 1 < I5EFAULT — UTRAN — PRIORITY: bit(3) >

< DEFAULT THRESH UTRAN: bit(5) >

< DEFAULT UTRAN QRXLEVMIN: bit(5) > }

Priority Parameters: < Repeated UTRAN Priority

< Repeated UTRAN Priority Parameters struct > ::=

{ 1 < UTRAN— FREQUENCY— INDEX: bit (5) > } ** 0

{ 0 I 1 < UTRAN PRIORITY: bit(3) > }

< THRESH UTRAN high: bit(5) >

{ 0 I 1 < THRESH UTRAN low: bit(5) > }

{ 0 I 1 < UTRAN QRXLEVMIN: bit(5) > };

It can be known from the above language that the UTRAN frequency index value is expressed as "UTRAN_FREQUENCY_INDEX", and the priority information of the UTRAN cell includes the default UTRAN cell priority (DEFAULT UTRAN PRIORITY) and the priority of the UTRAN cell frequency point (UTRAN- PRIORITY); The reselection threshold parameters of the UTRAN cell include: default UTRAN cell threshold (DEFAULT - THRESH - UTRAN), default UTRAN cell minimum reception level (DEFAULT - UTRAN - QRXLEVMIN), UTRAN cell frequency priority, UTRAN cell frequency point high threshold (THRESH_UTRAN_high), UTRAN cell frequency point threshold (THRESH_UTRAN_low) and UTRAN cell minimum reception level (UTRAN QRXLEVMIN)

It should be noted that, in fact, "UTRAN_Start/Stop" is used to indicate whether the UTRAN measurement reselection parameter in the SI2quater message is received, but because the UTRAN frequency information is small, it is generally issued earlier, and is not clear. The information indicating that the UTRAN frequency information has been transmitted is actually transmitted, and the frequency point information is also transmitted when the UTRAN frequency information is transmitted. Therefore, after the UTRAN measurement reselection parameter is determined according to "UTRAN_Start/Stop", the UTRAN frequency information can also be considered to have been received.

It can be understood that, in some embodiments, when the access network measurement reselection parameter in the SI2quater message can be specifically the measurement reselection parameter of the closed subscriber group CSG cell, the terminal receives the reselection with the UTRAN measurement carried in the SI2quater message. The UTRAN frequency point information corresponding to the parameter, after the terminal receives the full SI2quater message, determines that the UTRAN frequency point information corresponding to the UTRAN measurement reselection parameter carried in the SI2quater message is received.

The measurement reselection parameters of the CSG cell can be expressed as follows:

< 3G CSG Description struct > ::=

{ 1< CSG — PSC — SPLIT: < PSC Group IE »

{ 1< UTRAN FREQUENCY INDEX: bit (5) > } ** 0 } ** 0 { 1 { 0 < CSG_FDD_UARFCN: bit (14) > | 1 < CSG — TDD — UARFCN: bit (14) > } } ** 0 ;

The UTRAN CSG Dedicated Frequencies have the above-mentioned representation voice. The measurement reselection parameters of the CSG cell include the CSG cell frequency point index value and the CSG cell physical scrambling code information, wherein the CSG cell frequency point index value is expressed as CSG_FDD_UARFCN, The CSG cell physical scrambling code information is represented as CSG-PSC-SPLIT.
