Translated fromChinese技术领域technical field
本发明涉及无线技术领域，尤其是指一种小区接入方法、装置及终端。The present invention relates to the field of wireless technology, in particular to a cell access method, device and terminal.
背景技术Background technique
5G现网应用中需要5G小区支持非独立组网(Non－Stand Alone，NSA)和独立组网(Stand Alone，SA)组网双模终端同时接入并发起数据业务，其中NSA终端通过搜索长期演进(Long Term Evolution，LTE)系统消息、公共陆地移动网络(Public Land MobileNetwork，PLMN)选择、小区选择实现驻留到NSA锚点LTE小区，SA终端通过搜索NSA的新空口(New Radio，NR)系统小区、PLMN选择、小区选择实现驻留到NR小区。In 5G current network applications, 5G cells are required to support non-standalone (Non-Stand Alone, NSA) and stand-alone (Stand Alone, SA) dual-mode terminals to simultaneously access and initiate data services. Evolution (Long Term Evolution, LTE) system messages, public land mobile network (Public Land Mobile Network, PLMN) selection, cell selection to achieve camping in the NSA anchor LTE cell, the SA terminal searches for the new air interface (New Radio, NR) of the NSA The system cell, PLMN selection, and cell selection realize camping in the NR cell.
现有通信协议中，系统消息的主信息块(Master Information Block，MIB)消息中小区禁止cellBarred字段代表小区禁止参数，若终端读取为禁止barred，则表示该终端禁止驻留在该小区，反之则允许驻留。In the existing communication protocol, the cell barred field in the master information block (Master Information Block, MIB) message of the system message represents the cell barred parameter. If the terminal reads barred as barred, it means that the terminal is forbidden to camp in the cell, otherwise is allowed to reside.
假设NR侧系统消息MIB配置cellBarred为非禁止notBarred，对于5G小区存在NSA/SA双模终端来说，若SA终端在接入过程中接收cellBarred为notBarred则表示网络侧允许SA终端实现驻留，同时此时NSA终端在LTE侧实现驻留后，在添加NR辅载波前需要读取NR侧MIB消息以确定是否允许接入，但此时由于cellBarred已设置为notBarred，NSA终端若读取了notBarred，会继续在NR侧读取系统信息块(system information Block，SIB)类型1，并驻留在NR小区，这与NSA小区需要驻留在LTE锚点的初衷不符合，无法发挥LTE锚点更优覆盖性能的优势。Assume that the system message MIB on the NR side configures cellBarred as non-forbidden notBarred. For NSA/SA dual-mode terminals in the 5G cell, if the SA terminal receives cellBarred as notBarred during the access process, it means that the network side allows the SA terminal to camp. At this time, after the NSA terminal camps on the LTE side, it needs to read the MIB message on the NR side to determine whether to allow access before adding the NR secondary carrier. However, since cellBarred has been set to notBarred, if the NSA terminal reads notBarred, It will continue to read the system information block (system information block, SIB) type 1 on the NR side and reside in the NR cell, which is not in line with the original intention of the NSA cell to reside in the LTE anchor point, and cannot take advantage of the LTE anchor point. advantage of overlay performance.
因此，在目前协议中，在系统消息cellBarred配置下，无法实现NSA终端和SA终端同时接入相同5G小区，且实现NSA驻留在锚点LTE小区，SA驻留在NR小区的场景。Therefore, in the current protocol, under the configuration of the system message cellBarred, the NSA terminal and the SA terminal cannot access the same 5G cell at the same time, and realize the scenario where the NSA resides in the anchor LTE cell and the SA resides in the NR cell.

具体实施方式Detailed ways
为使本发明要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
为解决常规技术在系统消息cellBarred配置下，无法实现NSA终端和SA终端同时接入相同5G小区，且实现NSA终端驻留在锚点LTE小区，SA驻留在NR小区的问题，本发明实施例提供一种小区接入方法，当系统消息cellBarred参数被指示为非禁止时，不同模式终端对于该cellBarred参数的判定不同，以能够保证NSA终端和SA终端能够同时接入相同5G小区，实现NSA终端驻留在锚点LTE小区，SA驻留在NR小区。In order to solve the problem that the conventional technology cannot realize that the NSA terminal and the SA terminal can access the same 5G cell at the same time under the configuration of the system message cellBarred, and realize that the NSA terminal resides in the anchor LTE cell and the SA resides in the NR cell, the embodiment of the present invention Provide a cell access method. When the system message cellBarred parameter is indicated as non-prohibited, terminals in different modes make different judgments on the cellBarred parameter, so as to ensure that NSA terminals and SA terminals can access the same 5G cell at the same time, and realize NSA terminal The SA resides in the anchor LTE cell, and the SA resides in the NR cell.
具体地，本发明实施例提供一种小区接入方法，应用于终端，如图1所示，所述方法包括：Specifically, an embodiment of the present invention provides a cell access method, which is applied to a terminal. As shown in FIG. 1, the method includes:
S110，获取新空口NR系统的目标小区发送的主信息块MIB消息；S110, acquiring a master information block MIB message sent by a target cell of a new air interface NR system;
S120，所述终端为独立组网SA终端时，若所述MIB消息中的小区禁止参数记录为非禁止指示信息，则判定所述目标小区为非禁止接入；所述终端为非独立组网NSA终端时，若所述MIB消息中的小区禁止参数记录为非禁止指示信息，则判定所述目标小区为禁止接入。S120. When the terminal is an SA terminal in an independent networking, if the cell barring parameter record in the MIB message is non-barring indication information, determine that the target cell is not barring access; the terminal is in a non-independent networking In the case of an NSA terminal, if the cell barring parameter record in the MIB message is non-barring indication information, it is determined that the target cell is barred from access.
通过上述实施例的小区接入方法，当目标小区将MIB消息中的小区禁止(cellBarred)参数设置为非禁止(notBarred)指示信息，允许目标小区内终端接入并实现驻留时，对于接收该MIB消息的SA终端，根据该cellBarred参数，判定目标小区为非禁止接入，以能够将该目标小区作为小区选择的候选小区，进一步驻留在该目标小区；对于接收该MIB消息的NSA终端，根据该cellBarred参数，则判定目标小区为禁止接入，以能够保持LTE小区驻留，并继续完成辅载波添加和随机接入过程。Through the cell access method of the above embodiment, when the target cell sets the cell barred (cellBarred) parameter in the MIB message to non-barred (notBarred) indication information, allowing the terminal in the target cell to access and implement camping, for receiving the The SA terminal of the MIB message, according to the cellBarred parameter, determines that the target cell is not prohibited from accessing, so that the target cell can be used as a candidate cell for cell selection, and further resides in the target cell; for the NSA terminal receiving the MIB message, According to the cellBarred parameter, it is determined that the target cell is prohibited from being accessed, so as to keep the LTE cell camped on, and continue to complete the secondary carrier addition and random access process.
因此，采用本发明实施例所述小区接入方法，当系统消息cellBarred参数被指示为非禁止时，不同模式终端对于该cellBarred参数的判定不同，以能够保证NSA终端和SA终端能够同时接入相同5G小区，实现NSA终端驻留在锚点LTE小区，SA驻留在NR小区。Therefore, using the cell access method described in the embodiment of the present invention, when the system message cellBarred parameter is indicated as non-prohibited, terminals in different modes make different judgments on the cellBarred parameter, so as to ensure that NSA terminals and SA terminals can access the same cell at the same time. In the 5G cell, the NSA terminal resides in the anchor LTE cell, and the SA resides in the NR cell.
需要说明的是，终端从开机到驻留小区涉及的主要流程包括：频点扫描和下行同步、系统信息读取、PLMN选择、小区选择及重选、位置区注册等。其中，频点扫描和下行同步主要涉及的是物理层流程，与高层相关的流程主要包括：系统信息读取、PLMN选择、小区选择及重选和位置区注册。其中，系统信息主要是为终端提供小区级的配置信息，让终端能够执行小区选择、小区重选等操作，系统信息(System Information，SI)分为最小系统信息(Minimum SI)和其他系统信息(Other SI)两部分，最小系统信息使用两个不同的消息(主信息块：MIB和系统信息块类型1：SIB1)。It should be noted that the main process involved in the terminal from starting up to camping on the cell includes: frequency point scanning and downlink synchronization, system information reading, PLMN selection, cell selection and reselection, location area registration, etc. Among them, frequency point scanning and downlink synchronization mainly involve the physical layer process, and high-level related processes mainly include: system information reading, PLMN selection, cell selection and reselection, and location area registration. Among them, the system information is mainly to provide cell-level configuration information for the terminal, so that the terminal can perform operations such as cell selection and cell reselection. The system information (System Information, SI) is divided into minimum system information (Minimum SI) and other system information ( Other SI) two parts, the minimum system information uses two different messages (Master Information Block: MIB and System Information Block Type 1: SIB1).
具体地，每个终端UE可以驻留的小区至少要广播一部分最小系统信息。对于终端UE可以驻留的小区/载频，UE不会被要求从其他小区/载频获取当前小区/载频的最小系统信息。如果UE不能获得某一小区的所有最小系统信息(包括从小区接收的，或者之前存储的有关该小区的有效系统信息)，则UE可以判定为该小区被禁止了。Specifically, at least a part of the minimum system information is broadcast in a cell where each terminal UE can camp. For the cell/carrier frequency where the terminal UE can camp, the UE is not required to obtain the minimum system information of the current cell/carrier frequency from other cells/carrier frequencies. If the UE cannot obtain all minimum system information of a certain cell (including valid system information received from the cell or previously stored on the cell), the UE may determine that the cell is barred.
当目标小区发送的主信息块MIB消息的cellBarred参数为非禁止指示信息时，表示目标小区允许驻留。When the cellBarred parameter of the MIB message sent by the target cell is non-barred indication information, it means that the target cell is allowed to camp.
采用本发明实施例所述小区接入方法，对于SA终端，当SA终端开机后，在接入小区的过程中，依次执行扫描频点和进行小区搜索和下行同步，其中包括读取目标小区发送的主信息块MIB消息的过程，当所获取的主信息块MIB消息中，小区禁止cellBarred参数为非禁止指示信息时，则SA终端判定目标小区为非禁止接入，则确定该目标小区为能够用于驻留的侯选小区，也即执行上述的步骤S110和S120。Using the cell access method described in the embodiment of the present invention, for the SA terminal, when the SA terminal is turned on, in the process of accessing the cell, it sequentially performs frequency scanning, cell search and downlink synchronization, including reading the target cell to send In the process of the master information block MIB message, when the obtained master information block MIB message shows that the cell barred parameter of cell Barred is non-barred indication information, the SA terminal determines that the target cell is not barred from access, and then determines that the target cell is usable In the candidate cell where the cell resides, that is, the above steps S110 and S120 are performed.
进一步地，进行小区搜索和下行同步的过程还包括：Further, the process of cell search and downlink synchronization also includes:
读取系统信息块SIB类型1、进行PLMN选择和小区选择，以接入并驻留在目标小区。Read system information block SIB type 1, perform PLMN selection and cell selection to access and camp on the target cell.
通过上述的过程，在NA系统的目标小区发送的主信息块MIB消息中，小区禁止cellBarred参数为非禁止指示信息的情况下，SA终端能够驻留在NR小区。Through the above process, in the master information block MIB message sent by the target cell of the NA system, the cell barred parameter is the non-barred indication information, and the SA terminal can camp on the NR cell.
采用本发明实施例所述小区接入方法，对于NSA终端，当在步骤S110，所获取的主信息块MIB消息中，小区禁止cellBarred参数为非禁止指示信息时，NSA终端判定目标小区为禁止接入；进一步地，所述方法还包括：Using the cell access method described in the embodiment of the present invention, for the NSA terminal, when in step S110, in the obtained master information block MIB message, the cell barred parameter of the cell Barred is non-barred indication information, the NSA terminal determines that the target cell is barred from accessing into; further, the method also includes:
若所述MIB消息中的小区禁止参数记录为非禁止指示信息，则放弃在所述NR系统读取系统信息块SIB类型1；以及If the cell prohibition parameter record in the MIB message is non-prohibition indication information, abandon reading the system information block SIB type 1 in the NR system; and
确定所述目标小区并非为能够用于驻留的侯选小区。It is determined that the target cell is not a candidate cell for camping on.
具体地，NSA终端开机以后，会从锚点LTE侧实现驻留，在添加NR副载波过程中，需要读取NR系统消息MIB，以确定目标小区是否允许接入。当MIB消息中的小区禁止cellBarred参数为非禁止指示信息时，若NSA终端将cellBarred参数读取为非禁止指示，会继续在NR系统侧读取SIB1，并驻留在NR小区，会与NSA终端需要驻留在LTE锚点的初衷不符合，无法发挥LTE锚点更优覆盖性能的优势，并无法实现NSA驻留在锚点LTE小区，SA驻留在NR小区的场景。而采用本发明实施例所述小区接入方法，当MIB消息中的小区禁止cellBarred参数为非禁止指示信息时，NSA终端将cellBarred参数读取为禁止指示，也即判定目标小区为禁止接入。Specifically, after the NSA terminal is powered on, it will camp on the anchor LTE side. During the process of adding NR subcarriers, it needs to read the NR system information MIB to determine whether the target cell is allowed to access. When the cell Barred parameter in the MIB message is non-barred indication information, if the NSA terminal reads the cellBarred parameter as a non-barred indication, it will continue to read SIB1 on the NR system side, and reside in the NR cell, and will communicate with the NSA terminal The original intention of camping on the LTE anchor point is not met, and the advantages of better coverage performance of the LTE anchor point cannot be used, and the scenario where the NSA resides in the anchor LTE cell and the SA resides in the NR cell cannot be realized. With the cell access method described in the embodiment of the present invention, when the cell barred parameter in the MIB message is non-barred indication information, the NSA terminal reads the cellBarred parameter as a barred indication, that is, determines that the target cell is barred from access.
在此基础上，NSA终端不会继续在NR侧读取SIB1消息，以保持LTE小区驻留，之后继续完成辅载波添加和随机接入流程，以能够接入5G小区。On this basis, the NSA terminal will not continue to read the SIB1 message on the NR side to keep the LTE cell camped, and then continue to complete the secondary carrier addition and random access procedures to be able to access the 5G cell.
因此，采用本发明实施例所述小区接入方法，当NSA终端驻留在锚点LTE小区后，在小区选择过程中，终端不会再将NR小区作为候选小区，而是驻留在锚点LTE小区。Therefore, using the cell access method described in the embodiment of the present invention, when the NSA terminal camps in the anchor LTE cell, the terminal will no longer use the NR cell as a candidate cell during the cell selection process, but will reside in the anchor cell LTE cells.
当目标小区的系统消息cellBarred参数被指示为非禁止时，NSA终端和SA终端对于该cellBarred参数的判定不同。通过该方式，能够实现NSA终端和SA终端同时接入相同5G小区，且实现NSA驻留在锚点LTE小区，SA驻留在NR小区的目的。When the cellBarred parameter of the system message of the target cell is indicated as non-barred, the determination of the cellBarred parameter by the NSA terminal and the SA terminal is different. In this way, the NSA terminal and the SA terminal can access the same 5G cell at the same time, and realize the purpose that the NSA resides in the anchor LTE cell and the SA resides in the NR cell.
本发明实施例还提供一种终端，如图2所示，该终端包括收发机210和处理器220，其中：The embodiment of the present invention also provides a terminal. As shown in FIG. 2, the terminal includes a
