Description

Method and system for issuing network configuration parameters

technical field

The invention relates to the field of wireless technology in the communication industry, in particular to a method and system for sending network configuration parameters.

Background technique

According to the existing 3GPP standards, the procedure for a terminal to boot up and reside on the network is as follows: when the terminal is powered on, select the PLMN first, and after selecting the PLMN, the terminal searches for a cell. After successfully searching for a cell, the terminal reads the system information and confirms the main information block (Main Whether the PLMN ID in the Info Block (MIB for short) is the same as the selected PLMN, after confirming that it is correct, the terminal starts to receive other System Info Blocks (SIB for short), such as SIB1, SIB3, SIB5, SIB11, etc. So far, Terminal initialization is complete. FIG. 1 is a flowchart of a terminal reading a BCCH broadcast channel message in the prior art. As shown in Figure 1, including:

Step S002: start the terminal, search the network, and start reading system messages;

Step S004: Whether the PLMN ID in the MIB information block is the same as the selected PLMN, if identical, perform step S006, otherwise, perform step S020;

Step S006: Whether the reading of SIB3 is successful, if successful, execute step S008, otherwise, execute step S020;

Step S008: finding a suitable cell;

Step S010: Whether the reading of SIB5 and SIB11 is successful, if successful, execute step S012, otherwise, execute step S020;

Step S012: read SIB5, obtain common channel parameters, and configure it to the bottom layer, read SIB11, and obtain measurement control information;

Step S014: Whether the reading of SIB1 is successful, if successful, execute step S016, otherwise, execute step S020;

Step S016: Read SIB1, obtain CN system information required by NAS, and report to the network;

Step S018: The terminal successfully camps in the cell, and the process ends;

Step S020: The terminal cannot reside in the network, and ends abnormally.

After the terminal searches for a suitable cell, it needs to read the SIB5 message to obtain the common channel parameters and configure them to the bottom layer of the terminal. If the reading of SIB5 fails or the reading information is wrong, the terminal cannot successfully camp on the cell. The SIB5 is carried by the BCCH (broadcast channel) channel of the cell, and is a system message body that the terminal must read. SIB5 mainly contains the configuration parameter information of the public physical channel, which includes the relevant IE (Information Element) field information related to both MBMS and HSUPA in the 3GPP mechanism, and the MBMS and HSUPA related function fields are included in the same IE, and are used together by the network sent to the terminal.

During the evolution of the TD-MBMS standard, there was a compatibility problem between the V3 version and the V2+MBMS0711 version of ASN.1, that is, there was a compatibility problem between the versions before and after the SIB5 message, and the terminal could not receive the SIB5 message normally, causing the terminal to fail to work normally. reside on the network. In order to solve the problem that the problem terminal cannot reside on the network, we must close the delivery of the relevant IE in the SIB5 message. However, since this IE also contains HSUPA field information, the HSUPA terminal cannot receive the HSUPA message. can not work normally.

In the process of realizing the present invention, the inventor found that the prior art network configuration parameter distribution method has the following defects: for multiple network configuration parameters with high coupling in the same information block, once any problem occurs, it will cause the terminal The network parameters cannot be read correctly and cannot work normally.

The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

Detailed ways

Embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

Embodiment one

This embodiment proposes a method for delivering network configuration parameters, in which coupled network configuration parameters are delivered to terminals in SIB information blocks and RRC messages respectively. The network configuration parameters may be system configuration parameters carried in the public physical channel, and the SIB information block is the SIB5 information block.

Coupling network configuration parameters, that is, multiple system parameters are included in the same system information block, and each parameter is a mandatory parameter in this system information block. The configuration of all parameters is only related to the system information block to which If the system information block is closed, all parameters are not configured; if the system information block is enabled, all parameters are configured. Therefore, there is a high coupling among the parameters, for example, system parameters such as MBMS, HSUPA, HSPA+, and PRACH included in SIB5.

Taking the MBMS system information and HSUPA system information in the SIB5 information block as an example: the MBMS system information is delivered to the terminal through the SIB5 information block, and the HSUPA system information is delivered to the terminal through the extension field of the RRC message. Specifically, the extended field of the RRC message is SYNC-UL-InfoForE-RUCCH of RRCConnectionSetup-r7-IEs in the RRC message.

In this embodiment, a method and system for delivering network configuration parameters are proposed, which deliver multiple network configuration parameters with high coupling respectively to reduce the coupling between network configuration parameters.

Embodiment two

This embodiment will take the actual problem solving as an example to specifically illustrate the process of the method for delivering network configuration parameters. In the existing mechanism for sending MBMS and HSUPA system messages, the sending of MBMS and HSUPA system messages has a high degree of coupling. At the same time, the existing MBMS standard and HSUPA standard are both developing and changing. Due to the high coupling of MBMS and HSUPA system messages, once any problem occurs in either party, the terminal will not be able to receive the entire IE, resulting in the terminal not working normally.

In the process of solving the problem mentioned in the prior art, in the optional extension field of the RRC message structure RRCConnectionSetup-r7-IEs, add the HSUPA related message field, and no longer send it in the original SIB5 system information block SysInfoType5-v770ext-IEs HSUPA message field. In this way, MBMS and HSUPA message delivery paths can be separated, and when any problem occurs on one side, the normal work of the other side will not be affected. FIG. 2 is a signaling diagram of a method for sending network configuration parameters according to Embodiment 2 of the present invention. As shown in Figure 2, this embodiment includes:

Step S202, UE sends RRC CONNECTION REQUEST message to UTRAN;

Step S204, UTRAN sends a RRC CONNECTION SETUP message to UE, and adds HSUPA-related message fields in the optional extension field of RRCConnectionSetup-r7-IEs;

In step S206, the RRC connection is established successfully, and the UE sends an RRCCONNECTION SETUP COMPLETE message to the UTRAN.

In an actual scenario, when the HSUPA message needs to be delivered in information other than SIB5, the network side configures the e-RUCCH-Sync-UL-Codes- The Bitmap field is configured in the SYNC-UL-InfoForE-RUCCH of the RRC message structure RRCConnectionSetup-r7-IEs, which realizes the separate transmission of MBMS and HSUPA messages. At the same time, close the SIB5SysInfoType5-v770ext-IEs field in the system message. After the terminal is powered on, it does not receive HSUPA messages from system messages, but reads HSUPA-related messages during the RRC connection establishment process. This not only solves the problem that the problem terminal cannot reside in the network, but also ensures that the HSUPA terminal can receive all the information normally and work normally.

FIG. 3 is a flowchart of a method for issuing network configuration parameters according to Embodiment 2 of the present invention. As shown in Figure 3, this embodiment includes:

Step S252, network parameter configuration, that is, determine whether to configure the HSUPA system message in the RRC message structure according to needs;

Step S254, the terminal is turned on, searches for the PLMN, and finds a suitable cell;

Step S256, the terminal reads messages such as SIB1, SIB3, and SIB5;

Step S258, the terminal successfully camps on the network;

Step S260, the terminal performs services and initiates an RRC connection;

Step S262, whether the terminal has read the HSUPA message from SIB5, if it has read it, execute step S266; otherwise, execute step S264;

Step S264, read the HSUPA message from the RRC message structure;

Step S266, do not read the HSUPA message in the RRC message structure;

In step S268, the RRC establishment of the terminal is completed, and the terminal starts to work normally.

Under the existing message delivery mechanism, MBMS and HSUPA message delivery are highly coupled. When one party has a problem, such as version compatibility, it is not easy to solve the problem of one party without affecting the other party. The invention provides an effective solution, sends MBMS and HSUPA messages through different channels, eliminates the coupling between the two, and does not affect the work of the other party when solving the problem of one party. For example, when MBMS has a compatibility problem, after closing the SIB5-related problem field, the HSUPA message is sent through the RRC message, which will not affect the normal operation of the HSUPA terminal. The solution is simple to implement, effective in improvement, and strong in usability.

On the basis of the first embodiment, this embodiment solves the practical problems in the evolution process of the TD-MBMS standard by using the method of the present invention. In addition, the present invention can also be applied to various networks such as WCDMA and TD-SCDMA, and can solve related problems in the existing network by separately sending the affected tightly coupled signaling.
