本发明涉及无线通信技术领域，尤其涉及一种终端接入方法、系统及装置。The present invention relates to the technical field of wireless communication, in particular to a terminal access method, system and device.
背景技术Background technique
3GPP的标准中定义了LTE的工作频段。在R8、R9和R10版本阶段支持的工作频段数目为64个，其中，第1个到第32个工作频段为FDD频段，第33个到第64个工作频段为TDD频段。在LTE的系统信息中定义了网络侧的工作频段指示信息，指示的网络工作在频段列表中的某一频段。然而随着LTE在全球市场的迅速发展，频段列表资源已经接近枯竭，尤其是FDD的频段资源，需要扩展频段列表的最大承载能力。The working frequency band of LTE is defined in the standard of 3GPP. The number of working frequency bands supported in the R8, R9 and R10 versions is 64, of which the 1st to 32nd working frequency bands are FDD frequency bands, and the 33rd to 64th working frequency bands are TDD frequency bands. The working frequency band indication information on the network side is defined in the LTE system information, and the indicated network works in a certain frequency band in the frequency band list. However, with the rapid development of LTE in the global market, frequency band list resources are almost exhausted, especially for FDD frequency band resources, and the maximum carrying capacity of the frequency band list needs to be expanded.
为了满足LTE快速发展的需求，需要扩展频段列表的最大承载能力，并更新相应的工作频段指示信息，一种简单的方法是在R11版本规范中扩展现有的工作频段指示信息参数的位数，但这将造成后向兼容性问题，即R8、R9和R10版本终端无法接入R11版本基站。例如，在R11版本的基站中，将现有的工作频段指示信息，从原来的6个比特（bits）指示第1个到第64个工作频段，改为采用7个bits指示第1个到第128个工作频段。这样会使得原有的R8、R9和R10版本的终端无法识别该工作频段指示信息，从而导致无法接入R11版本的网络，造成后向兼容性的问题。In order to meet the needs of the rapid development of LTE, it is necessary to expand the maximum carrying capacity of the frequency band list and update the corresponding working frequency band indication information. A simple method is to expand the number of digits of the existing working frequency band indication information parameters in the R11 version specification. However, this will cause backward compatibility issues, that is, R8, R9 and R10 version terminals cannot access R11 version base stations. For example, in the base station of the R11 version, the existing working frequency band indication information is changed from the original 6 bits (bits) indicating the 1st to the 64th working frequency bands to 7 bits indicating the 1st to the 64th working frequency bands. 128 working frequency bands. This will make the terminals of the original R8, R9 and R10 versions unable to recognize the indication information of the working frequency band, thus making it impossible to access the network of the R11 version, resulting in a problem of backward compatibility.

具体实施方式detailed description
下面结合附图，具体描述本发明的具体实施方式：Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:
由于频段列表资源日渐枯竭，需要对原有的工作频段进行扩展，本发明的技术方案就是解决在对原有工作频段进行扩展后，终端如何接入的问题。为了能够清楚的描述本发明技术方案，下面将以3GPP的R8、R9、R10版本的协议中支持的工作频段数目最大为64，在R11版本的协议中工作频段数目扩大为128，作为实施例进行说明，其中前面64个工作频段保持不变，后面64个工作频段是扩展的工作频段。Since the resources of the frequency band list are exhausted day by day, the original working frequency band needs to be extended. The technical solution of the present invention is to solve the problem of how the terminal accesses after the original working frequency band is extended. In order to clearly describe the technical solution of the present invention, the maximum number of operating frequency bands supported in the protocols of the R8, R9, and R10 versions of 3GPP is 64, and the number of operating frequency bands is expanded to 128 in the protocol of the R11 version, as an embodiment. Note that the first 64 working frequency bands remain unchanged, and the latter 64 working frequency bands are extended working frequency bands.
图1是本发明终端接入实施方式一的流程图。如图1所示，该终端接入流程包括以下步骤：FIG. 1 is a flowchart of Embodiment 1 of terminal access in the present invention. As shown in Figure 1, the terminal access process includes the following steps:
步骤101、网络侧在系统信息中向终端下发工作频段指示信息和辅助工作频段指示信息，用于指示工作频段。Step 101 , the network side issues working frequency band indication information and auxiliary working frequency band indication information to the terminal in the system information for indicating the working frequency band.
其中工作频段指示信息和辅助工作频段指示信息结合使用，用来指示扩展后的工作频段。The working frequency band indication information and the auxiliary working frequency band indication information are used in combination to indicate the extended working frequency band.
工作频段从64个（26个，即N=6）扩展到128个（27个=26+1，即N=6，M=1）时，工作频段指示信息为6bits，指示了前面64个工作频段，辅助工作频段指示信息为1bit，与工作频段指示信息结合在一起，指示所有的128个工作频段。When the working frequency band is expanded from 64 (26 , ie N=6) to 128 (27 = 26+1 , ie N=6, M=1), the working frequency band indication information is 6bits, indicating the previous There are 64 working frequency bands, and the auxiliary working frequency band indication information is 1 bit, which is combined with the working frequency band indication information to indicate all 128 working frequency bands.
当辅助工作频段指示信息为0时，工作频段指示信息和辅助工作频段指示信息结合起来指示第1个工作频段到第64个工作频段，当辅助工作频段指示信息为1时，工作频段指示信息和辅助工作频段指示信息结合起来指示第65个工作频段到第128个工作频段。When the auxiliary working frequency band indication information is 0, the working frequency band indication information and the auxiliary working frequency band indication information are combined to indicate the first working frequency band to the 64th working frequency band; when the auxiliary working frequency band indication information is 1, the working frequency band indication information and The auxiliary working frequency band indication information is combined to indicate the 65th working frequency band to the 128th working frequency band.
如工作频段指示信息为000 000，辅助工作频段指示信息为0，两者的结合指示的是第1个工作频段；如工作频段指示信息为000 000，辅助工作频段指示信息为1，两者的结合指示的是第65个工作频段。If the indication information of the working frequency band is 000 000 and the indication information of the auxiliary working frequency band is 0, the combination of the two indicates the first working frequency band; if the indication information of the working frequency band is 000 000 and the indication information of the auxiliary working frequency band is 1, the Combined indication is the 65th working frequency band.
步骤102、终端接收到网络侧下发的工作频段指示信息和辅助工作频段指示信息，判断根据工作频段指示信息和辅助工作频段指示信息结合起来确定的工作频段是否为终端支持的工作频段的一部分，如果支持，则转至步骤103，如果不支持，则转至步骤104。Step 102, the terminal receives the working frequency band indication information and the auxiliary working frequency band indication information issued by the network side, and judges whether the working frequency band determined according to the combination of the working frequency band indication information and the auxiliary working frequency band indication information is a part of the working frequency band supported by the terminal, If yes, go to step 103, if not, go to step 104.
由于终端类型不同，具体判断过程也有所不同。Due to different terminal types, the specific judgment process is also different.
对于只支持接收工作频段指示信息的R8、R9和R10版本的终端，辅助工作频段指示信息对其是不可见的，这些版本的终端只根据6bits的工作频段指示信息，判断工作频段指示信息所确定的工作频段是否在自己支持的工作频段中，如果在，则判断支持工作频段，如果不在，则判断不支持工作频段。For R8, R9, and R10 versions of terminals that only support receiving working frequency band indication information, the auxiliary working frequency band indication information is invisible to them. Terminals of these versions only judge the working frequency band indication information according to the 6bits working frequency band indication information. Whether the working frequency band of the user is in the working frequency band supported by itself, if it is, it is judged that the working frequency band is supported, and if it is not, it is judged that the working frequency band is not supported.
对于支持同时接收工作频段指示信息和辅助工作频段指示信息的R11版本的终端，终端根据工作频段指示信息和辅助工作频段指示信息，判断工作频段指示信息和辅助工作频段指示信息结合起来确定的工作频段是否为终端支持的工作频段的一部分，如果在，则判断支持工作频段，如果不在，则判断不支持工作频段。For a terminal of the R11 version that supports simultaneous reception of the working frequency band indication information and the auxiliary working frequency band indication information, the terminal judges the working frequency band determined by combining the working frequency band indication information and the auxiliary working frequency band indication information according to the working frequency band indication information and the auxiliary working frequency band indication information Whether it is a part of the working frequency band supported by the terminal, if it is, it is judged that the working frequency band is supported, and if it is not, it is judged that the working frequency band is not supported.
步骤103、终端向高层发送小区标识CellIdentity和跟踪区编码TrackingAreaCode。Step 103, the terminal sends the cell identity CellIdentity and the tracking area code TrackingAreaCode to the upper layer.
步骤104、终端将小区标识为禁止的。Step 104, the terminal marks the cell as forbidden.
对于从64个工作频段扩展到256个工作频段的情况，工作频段指示信息仍为6bits，辅助工作频段指示信息改为2bits，其他处理方式类似。For the case of expanding from 64 working frequency bands to 256 working frequency bands, the indication information of the working frequency band is still 6 bits, and the indication information of the auxiliary working frequency band is changed to 2 bits, and other processing methods are similar.
如果网络侧支持多个工作频段，网络侧将下发多个工作频段对应的多工作频段指示信息和辅助多工作频段指示信息给终端，其中多工作频段指示信息包括多个工作频段指示信息的序列，辅助多工作频段指示信息包括多个辅助工作频段指示信息的序列，如当基站支持两个工作频段时，对应的多工作频段指示信息为（000 000，000 001），辅助多工作频段指示信息为（0，1），则表示工作频段为第1个频段和第66个频段。If the network side supports multiple working frequency bands, the network side will send multiple working frequency band indication information and auxiliary multi-working frequency band indication information corresponding to the multiple working frequency bands to the terminal, wherein the multi-working frequency band indication information includes a sequence of multiple working frequency band indication information , the auxiliary multiple working frequency band indication information includes a sequence of multiple auxiliary working frequency band indication information. If it is (0, 1), it means that the working frequency bands are the 1st frequency band and the 66th frequency band.
终端只要根据上述的方法判断确定出网络侧下发的多工作频段指示信息和辅助多工作频段指示信息确定的工作频段中的一个或多个工作频段是否为终端支持的工作频段的一部分，如果是，终端向高层发送小区标识CellIdentity和跟踪区编码TrackingAreaCode，如果不是终端将小区标识为禁止的。The terminal only needs to judge and determine whether one or more working frequency bands in the working frequency bands determined by the multi-working frequency band indication information issued by the network side and the auxiliary multi-working frequency band indication information are part of the working frequency bands supported by the terminal according to the above method. , the terminal sends the cell identity CellIdentity and the tracking area code TrackingAreaCode to the upper layer, if not the terminal identifies the cell as prohibited.

对于只支持接收扩展前6bits工作频段指示信息的R8、R9和R10版本的终端，判断模块用于根据工作频段指示信息判断终端是否支持工作频段指示信息确定的工作频段。For terminals of R8, R9 and R10 versions that only support receiving the working frequency band indication information of 6 bits before the expansion, the judging module is used to judge whether the terminal supports the working frequency band determined by the working frequency band indication information according to the working frequency band indication information.
对于支持同时接收N+M比特的工作频段指示信息和辅助工作频段指示信息的R11版本的终端，判断模块用于根据工作频段指示信息和辅助工作频段指示信息判断终端是否支持工作频段指示信息和辅助工作频段指示信息结合起来确定的工作频段。For terminals of the R11 version that support simultaneous reception of N+M bits of working frequency band indication information and auxiliary working frequency band indication information, the judging module is used to judge whether the terminal supports the working frequency band indication information and auxiliary working frequency band indication information according to the working frequency band indication information and auxiliary working frequency band indication information. The working frequency band indication information is combined to determine the working frequency band.

The working frequency band indication information module is a 6-bit storage unit, and the auxiliary working frequency band indication information module is a 1-bit storage unit.
如果网络侧支持多个工作频段，用于存储多工作频段指示信息的工作频段指示信息模块的容积则相应加倍，用于辅助多工作频段指示信息的辅助工作频段指示信息模块的容积也相应加倍。If the network side supports multiple working frequency bands, the volume of the working frequency band indication information module for storing the multi-working frequency band indication information is correspondingly doubled, and the volume of the auxiliary working frequency band indication information module for assisting the multi-working frequency band indication information is also correspondingly doubled.
工作频段指示信息模块用于指示扩展前的工作频段。The working frequency band indication information module is used to indicate the working frequency band before expansion.

接收模块用于接收工作频段对应的工作频段指示信息和辅助工作频段指示信息。The receiving module is used for receiving the working frequency band indication information and the auxiliary working frequency band indication information corresponding to the working frequency band.
对于只支持接收工作频段指示信息的R8、R9和R10版本的终端，判断模块用于根据工作频段指示信息判断终端是否支持工作频段指示信息和辅助工作频段指示信息结合起来确定的工作频段。For terminals of R8, R9 and R10 versions that only support receiving the working frequency band indication information, the judging module is used to judge whether the terminal supports the working frequency band determined by combining the working frequency band indication information and the auxiliary working frequency band indication information according to the working frequency band indication information.
对于支持同时接收工作频段指示信息和辅助工作频段指示信息的R11版本的终端，判断模块用于根据工作频段指示信息和辅助工作频段指示信息判断终端是否支持工作频段指示信息和辅助工作频段指示信息结合起来确定的工作频段。For a terminal of the R11 version that supports simultaneous reception of the working frequency band indication information and the auxiliary working frequency band indication information, the judging module is used to judge whether the terminal supports the combination of the working frequency band indication information and the auxiliary working frequency band indication information according to the working frequency band indication information and the auxiliary working frequency band indication information Get up to determine the working frequency band.

图3是本发明终端接入实施方式二的流程图。如图3所示，该终端接入流程包括以下步骤：FIG. 3 is a flow chart of the second embodiment of terminal access in the present invention. As shown in Figure 3, the terminal access process includes the following steps:
步骤301、网络侧在系统信息中向终端下发工作频段指示信息和扩展工作频段指示信息，用于指示工作频段。Step 301 , the network side sends the working frequency band indication information and the extended working frequency band indication information to the terminal in the system information, which are used to indicate the working frequency band.
其中工作频段指示信息用来指示扩展前的工作频段，扩展工作频段指示信息用来指示扩展后的工作频段。The working frequency band indication information is used to indicate the working frequency band before extension, and the extended working frequency band indication information is used to indicate the expanded working frequency band.
工作频段从64个（26个，即N=6）扩展到128个（27个=26+1，即N=6，M=1）时，工作频段指示信息为6bits，指示了前面64个工作频段，扩展工作频段指示信息为7bits，能够独立指示所有的128个工作频段。When the working frequency band is expanded from 64 (26 , ie N=6) to 128 (27 = 26+1 , ie N=6, M=1), the working frequency band indication information is 6bits, indicating the previous There are 64 working frequency bands, and the indication information of the extended working frequency band is 7bits, which can independently indicate all 128 working frequency bands.
如工作频段指示信息为000 000，指示的是第1个工作频段；如扩展工作频段指示信息为1 000 000，指示的是第65个工作频段。If the indication information of the working frequency band is 000 000, it indicates the first working frequency band; if the indication information of the extended working frequency band is 1 000 000, it indicates the 65th working frequency band.
步骤302、终端接收到网络侧下发的工作频段指示信息和扩展工作频段指示信息，判断根据工作频段指示信息或扩展工作频段指示信息确定的工作频段是否为终端支持的工作频段的一部分，如果支持，则转至步骤303，如果不支持，则转至步骤304。Step 302, the terminal receives the working frequency band indication information and the extended working frequency band indication information issued by the network side, and judges whether the working frequency band determined according to the working frequency band indication information or the extended working frequency band indication information is a part of the working frequency band supported by the terminal, if supported , then go to step 303, if not, go to step 304.
由于终端类型不同，具体判断过程也有所不同。Due to different terminal types, the specific judgment process is also different.
对于只支持接收工作频段指示信息的R8、R9和R10版本的终端，扩展工作频段指示信息对其是无法接收的，这些版本的终端只根据6bits的工作频段指示信息，判断工作频段指示信息所确定的工作频段是否在自己支持的工作频段中，如果在，则判断支持工作频段，如果不在，则判断不支持工作频段。For terminals of R8, R9 and R10 versions that only support receiving working frequency band indication information, the extended working frequency band indication information cannot be received by them. Terminals of these versions only judge the working frequency band indication information according to the 6bits working frequency band indication information. Whether the working frequency band of the user is in the working frequency band supported by itself, if it is, it is judged that the working frequency band is supported, and if it is not, it is judged that the working frequency band is not supported.
对于支持接收工作频段指示信息的R11版本的终端，终端根据扩展工作频段指示信息，判断扩展工作频段指示信息所确定的工作频段是否在自己支持的工作频段中，如果在，则判断支持工作频段，如果不在，则判断不支持工作频段。For a terminal of the R11 version that supports receiving the working frequency band indication information, the terminal judges whether the working frequency band determined by the extended working frequency band indication information is in the working frequency band supported by itself according to the extended working frequency band indication information, and if so, then judges to support the working frequency band, If not, it is judged that the working frequency band is not supported.
步骤303、终端向高层发送小区标识CellIdentity和跟踪区编码TrackingAreaCode。Step 303, the terminal sends the cell identity CellIdentity and the tracking area code TrackingAreaCode to the upper layer.
步骤304、终端将小区标识为禁止的。Step 304, the terminal marks the cell as forbidden.
对于从64个工作频段扩展到256个工作频段的情况，工作频段指示信息仍为6bits，扩展工作频段指示信息改为8bits，其他处理方式类似。For the case of expanding from 64 working frequency bands to 256 working frequency bands, the indication information of the working frequency bands is still 6 bits, and the indication information of the extended working frequency bands is changed to 8 bits, and other processing methods are similar.
如果基站支持多个工作频段，基站将下发多个工作频段对应的多工作频段指示信息和扩展多工作频段指示信息给终端，即下发多工作频段指示信息和扩展多工作频段指示信息，其中多工作频段指示信息包括多个工作频段指示信息的序列，扩展多工作频段指示信息包括多个扩展工作频段指示信息的序列，如多工作频段指示信息为（000 000，000 001），表示工作频段为第1个频段和第2个频段，扩展多工作频段指示信息为（0 000 000，1 000 001），则表示工作频段为第1个频段和第66个频段。If the base station supports multiple working frequency bands, the base station will send the multi-working frequency band indication information and the extended multi-working frequency band indication information corresponding to the multiple working frequency bands to the terminal, that is, send the multi-working frequency band indication information and the extended multi-working frequency band indication information, where The multi-working frequency band indication information includes a sequence of multiple working frequency band indication information, and the extended multi-working frequency band indication information includes a sequence of multiple extended working frequency band indication information. For example, the multi-working frequency band indication information is (000 000, 000 001), indicating the working frequency band It is the first frequency band and the second frequency band, and the indication information of the extended multi-working frequency band is (0 000 000, 1 000 001), which means that the working frequency band is the first frequency band and the 66th frequency band.
终端只要根据上述的方法判断确定出网络侧下发的多工作频段指示信息或者扩展多工作频段指示信息确定的一个或者多个工作频段是否为终端支持的工作频段的一部分，如果是，终端向高层发送小区标识CellIdentity和跟踪区编码TrackingAreaCode，如果不是终端将小区标识为禁止的。The terminal only needs to judge and determine whether one or more working frequency bands determined by the multi-working frequency band indication information issued by the network side or the extended multi-working frequency band indication information are part of the working frequency bands supported by the terminal according to the above method. Send the cell identity CellIdentity and tracking area code TrackingAreaCode, if not the terminal identifies the cell as prohibited.

本发明还提供了一种基站，包括工作频段指示信息模块、扩展工作频段指示信息模块和发送模块。工作频段指示信息模块是6比特存储单元，扩展工作频段指示信息模块是7比特存储单元。The present invention also provides a base station, which includes a working frequency band indicating information module, an extended working frequency band indicating information module and a sending module. The working frequency band indication information module is a 6-bit storage unit, and the extended working frequency band indication information module is a 7-bit storage unit.
如果网络侧支持多个工作频段，用于存储多工作频段指示信息的工作频段指示信息模块的容积则相应加倍，用于存储扩展多工作频段指示信息的扩展工作频段指示信息模块的容积也相应加倍。If the network side supports multiple working frequency bands, the volume of the working frequency band indication information module for storing multi-working frequency band indication information is correspondingly doubled, and the volume of the extended working frequency band indication information module for storing extended multi-working frequency band indication information is also doubled accordingly .

由于采用了工作频段指示信息和扩展工作频段指示信息指示工作频段，老版本的终端可以只根据原有的工作频段指示信息接入网络，新版本的终端可以根据扩展工作频段指示信息获取扩展后工作频段的指示信息，接入网络，从而达到既扩展了工作频段，又实现了后向兼容的目的。Due to the use of the working frequency band indication information and the extended working frequency band indication information to indicate the working frequency band, the terminal of the old version can only access the network according to the original working frequency band indication information, and the terminal of the new version can obtain the extended working frequency according to the extended working frequency band indication information. The instruction information of the frequency band is connected to the network, so as to not only expand the working frequency band, but also realize the purpose of backward compatibility.
下面描述本发明的第三个具体实施方式。A third specific embodiment of the present invention is described below.
若扩展频段编号后的新版本基站（如基于Rel-11版本）的实际工作频段为65，网络侧在工作频段信息中若配置为1~64编号的任一频段（基站广播虚假频段，如频段45），并在扩展工作频段指示编号65的话，若在扩展频段编号之前的老版本终端（如基于Rel-11之前的版本）在射频上可以接收广播信息所在载频（即终端射频硬件能力能够支持频段65中基站目前所使用的载波），则有较小的概率，恰好网络侧在工作频段信息中配置的虚假频段编号（如频段45）是终端所有支持频段能力的一部分，匹配成功，终端将认为可以在网络侧播放的频率45上工作，终端向高层发送小区标识CellIdentity和跟踪区编码TrackingAreaCode，并可能在频段45的该载频上发起上行接入请求，此时，网络侧将可能无法接收到终端的请求接入信号（例如，网络侧是FDD制式，实际工作频段65的上下行频率间隔和虚假播报的频段45的上下行频率间隔不同，即两个频段相同的下行载波对应的上行载波不同），终端可能将重复发起接入请求而无法接入，或者即使网络侧接收到终端的接入请求（例如，网络侧是TDD制式，上下行载频相同），但网络侧发现终端的频段支持能力45与网络侧的工作频段65不同，将拒绝接入，但网络侧将不会告知终端为何拒绝，终端可能将重复发起接入请求而无法接入，上述问题都将导致终端的异常行为。因此，可以采用在规范中使用一个定义扩展工作频段前尚未被使用的频段编号作为特定值（例如，频段64），当终端接收到工作频段指示信息并检测到规范中约定的特定值后，如果终端不支持接收扩展工作频段信息，终端将认为网络侧的工作频段是其不支持的；如果终端支持接收扩展工作频段信息，终端将接收扩展工作频段信息，并判断是否支持根据扩展工作频段确定的频段，解决上述终端小概率下的异常行为的问题。具体实施方式如下所示。If the actual working frequency band of the new version base station after the extended frequency band number (for example, based on Rel-11 version) is 65, if the network side configures any frequency band numbered from 1 to 64 in the working frequency band information (the base station broadcasts false frequency bands, such as frequency band 45), and indicate the number 65 in the extended working frequency band, if the terminal of the old version before the extended frequency band number (for example, based on the version before Rel-11) can receive the carrier frequency of the broadcast information on the radio frequency (that is, the terminal radio frequency hardware capability can Supporting the carrier currently used by the base station in frequency band 65), there is a small probability. It happens that the false frequency band number (such as frequency band 45) configured in the working frequency band information on the network side is part of all supported frequency band capabilities of the terminal. If the matching is successful, the terminal It will be considered that it can work on the frequency 45 played by the network side. The terminal sends the cell identity CellIdentity and the tracking area code TrackingAreaCode to the upper layer, and may initiate an uplink access request on the carrier frequency of the frequency band 45. At this time, the network side may not be able to Receive the request access signal from the terminal (for example, the network side is FDD system, the uplink and downlink frequency interval of the actual working frequency band 65 is different from the uplink and downlink frequency interval of the falsely broadcast frequency band 45, that is, the uplink and downlink carriers corresponding to the two frequency bands are the same Carriers are different), the terminal may repeatedly initiate access requests and cannot access, or even if the network side receives the terminal's access request (for example, the network side is TDD mode, the uplink and downlink carrier frequencies are the same), but the network side finds that the terminal's The frequency band support capability 45 is different from the working frequency band 65 on the network side, and the access will be rejected, but the network side will not inform the terminal why it refuses, and the terminal may repeatedly initiate access requests and fail to access. The above problems will lead to abnormalities in the terminal Behavior. Therefore, a frequency band number that has not been used before defining the extended working frequency band can be used as a specific value in the specification (for example, frequency band 64). When the terminal receives the working frequency band indication information and detects the specific value agreed in the specification, if If the terminal does not support receiving extended working frequency band information, the terminal will consider the working frequency band on the network side to be unsupported; if the terminal supports receiving extended working frequency band information, the terminal will receive the extended working frequency band information and determine whether it supports the extended working frequency band. Frequency band, to solve the problem of abnormal behavior of the above-mentioned terminal with a small probability. A specific embodiment is as follows.
图5是本发明终端接入实施方式三的流程图。如图5所示，该终端接入流程包括以下步骤：FIG. 5 is a flow chart of the third embodiment of terminal access in the present invention. As shown in Figure 5, the terminal access process includes the following steps:
步骤501、网络侧在系统信息中向终端下发工作频段指示信息和扩展工作频段指示信息，用于指示工作频段。Step 501 , the network side sends the working frequency band indication information and the extended working frequency band indication information to the terminal in the system information, which are used to indicate the working frequency band.
其中工作频段指示信息用来指示扩展前的工作频段，扩展工作频段指示信息用来指示扩展后的工作频段。The working frequency band indication information is used to indicate the working frequency band before extension, and the extended working frequency band indication information is used to indicate the expanded working frequency band.
工作频段从64个（26个，即N=6）扩展到128个（27个=26+26，即N=6，M=6）时，工作频段指示信息为6bits，指示了前面64个工作频段。When the working frequency band is expanded from 64 (26 , that is, N=6) to 128 (27 =26 +26 , that is, N=6, M=6), the working frequency band indication information is 6 bits, indicating The front 64 working frequency bands.
网络侧预设一个特定值，该特定值为1~64中一个，例如为64。当工作频段指示信息为该特定值时，是用来指示不支持读取扩展工作频段信息的终端，网络侧发来的工作频段不可用，指示支持读取扩展工作频段信息的终端读取扩展工作频段指示信息对应的工作频段。为了防止工作频段指示信息为特定值时发生终端不能获得对应的工作频段，所以该特定值对应的工作频段是扩展工作频段指示信息或扩展多工作频段指示信息定义规范版本之前没有使用的空闲频段。A specific value is preset on the network side, and the specific value is one of 1-64, for example, 64. When the working frequency band indication information is the specific value, it is used to indicate that the terminal that does not support reading the extended working frequency band information, the working frequency band sent by the network side is unavailable, and indicates that the terminal that supports reading the extended working frequency band information reads the extended work The frequency band indicates the working frequency band corresponding to the information. In order to prevent the terminal from being unable to obtain the corresponding working frequency band when the working frequency band indication information is a specific value, the working frequency band corresponding to the specific value is an idle frequency band that has not been used before the definition specification version of the extended working frequency band indication information or the extended multi-working frequency band indication information.
扩展工作频段指示信息为6bits，当工作频段指示信息为该特定值时，扩展工作频段指示信息指示第65个频段到第128个频段。The extended working frequency band indication information is 6 bits, and when the working frequency band indication information is the specific value, the extended working frequency band indication information indicates the 65th frequency band to the 128th frequency band.
如工作频段指示信息为000 000，指示的是第1个工作频段；如工作频段指示信息为111 111，扩展工作频段指示信息为000 000，则指示的是第65个工作频段。If the indication information of the working frequency band is 000 000, it indicates the first working frequency band; if the indication information of the working frequency band is 111 111, and the indication information of the extended working frequency band is 000 000, it indicates the 65th working frequency band.
另外，扩展工作频段指示信息也可以是7bits，指示扩展后的第1个工作频段到第128个工作频段。In addition, the indication information of the extended working frequency band may also be 7 bits, indicating the first working frequency band to the 128th working frequency band after the expansion.
如工作频段指示信息为000 000，指示的是第1个工作频段；如工作频段指示信息为111 111，扩展工作频段指示信息为0 000 000，则指示的是第1个工作频段。If the indication information of the working frequency band is 000 000, it indicates the first working frequency band; if the indication information of the working frequency band is 111 111, and the indication information of the extended working frequency band is 0 000 000, it indicates the first working frequency band.
步骤502、当终端接收到网络侧下发的工作频段指示信息和扩展工作频段指示信息，判断该工作频段指示信息是否为预设的特定值，如果不是，则转至步骤503；如果是，则转至步骤504。Step 502, when the terminal receives the working frequency band indication information and the extended working frequency band indication information issued by the network side, judge whether the working frequency band indication information is a preset specific value, if not, go to step 503; if yes, then Go to step 504.
步骤503、该终端根据工作频段指示信息，判断是否支持工作频段指示信息确定的工作频段，如果支持，则转至步骤507，如果不支持，则转至步骤508。Step 503 , the terminal judges whether the working frequency band determined by the working frequency band indication information is supported according to the working frequency band indication information, if yes, go to step 507 , if not, go to step 508 .
步骤504、判断该终端是否支持接收扩展工作频段指示信息，如果不支持，则转至步骤505；如果支持，则转至步骤506。Step 504, judging whether the terminal supports receiving extended working frequency band indication information, if not, go to step 505; if yes, go to step 506.
步骤505、终端判断不支持工作频段指示信息确定的工作频段，并转至步骤508。Step 505, the terminal judges that the working frequency band determined by the working frequency band indication information is not supported, and proceeds to step 508.
步骤506、终端则根据扩展工作频段指示信息，判断是否支持扩展工作频段指示信息确定的工作频段，如果支持，则转至步骤507；如果不支持，则转至步骤507。Step 506 , the terminal judges whether the working frequency band determined by the extended working frequency band indication information is supported according to the extended working frequency band indication information, and if yes, proceeds to step 507 ; if not, proceeds to step 507 .
步骤507、终端向高层发送小区标识CellIdentity和跟踪区编码TrackingAreaCode。Step 507, the terminal sends the cell identity CellIdentity and the tracking area code TrackingAreaCode to the upper layer.
步骤508、终端将小区标识为禁止的。Step 508, the terminal identifies the cell as forbidden.
对于从64个工作频段扩展到256个工作频段的情况，工作频段指示信息仍为6bits，则增加第二扩展工作频段指示信息，第一扩展工作频段指示信息为6bits，指示第65个频段到第128个频段，第二扩展工作频段指示信息为6bits，指示第129个频段到第192个频段，第三扩展工作频段指示信息为6bits，指示第193个频段到第256个频段，如此类推，其他处理方式类似。For the case of extending from 64 working frequency bands to 256 working frequency bands, the working frequency band indication information is still 6bits, then the second extended working frequency band indication information is added, the first extended working frequency band indication information is 6bits, indicating the 65th frequency band to the 6th 128 frequency bands, the indication information of the second extended working frequency band is 6bits, indicating the 129th frequency band to the 192nd frequency band, the indication information of the third extended working frequency band is 6bits, indicating the 193rd frequency band to the 256th frequency band, and so on, others It is handled similarly.
如果基站支持多个工作频段，基站将下发多个工作频段对应的多工作频段指示信息和扩展多工作频段指示信息给终端，即下发多工作频段指示信息和扩展多工作频段指示信息，其中多工作频段指示信息包括多个工作频段指示信息的序列，扩展多工作频段指示信息包括多个扩展工作频段指示信息的序列，这时，需要为多工作频段指示信息中的一项或多项预设对应的特定值。为了方便终端实现起见，可以设置成同一个特定值。If the base station supports multiple working frequency bands, the base station will send the multi-working frequency band indication information and the extended multi-working frequency band indication information corresponding to the multiple working frequency bands to the terminal, that is, send the multi-working frequency band indication information and the extended multi-working frequency band indication information, where The multi-working frequency band indication information includes a sequence of multiple working frequency band indication information, and the extended multi-working frequency band indication information includes a plurality of sequences of extended working frequency band indication information. Set the corresponding specific value. For the convenience of terminal implementation, it can be set to the same specific value.
假设特定值为64，对应比特编码为111 111，则如多工作频段指示信息为（000 000，111 111），扩展多工作频段指示信息为（000 000，000 001），则表示工作频段为第1个、第65个和第66个工作频段。Assuming that the specific value is 64 and the corresponding bit code is 111 111, if the multi-working frequency band indication information is (000 000, 111 111), and the extended multi-working frequency band indication information is (000 000, 000 001), it means that the working frequency band is the first 1st, 65th and 66th working frequency bands.
对于基站将下发多个工作频段对应的多工作频段指示信息和扩展多工作频段指示信息给终端，终端将逐个按照上述的方法判断确定出网络侧下发的多工作频段指示信息或者扩展多工作频段指示信息确定的一个或者多个工作频段是否为终端支持的工作频段的一部分，如果是，终端向高层发送小区标识CellIdentity和跟踪区编码TrackingAreaCode，如果不是终端将小区标识为禁止的。The base station will send the multi-working frequency band indication information corresponding to multiple working frequency bands and the extended multi-working frequency band indication information to the terminal, and the terminal will judge and determine the multi-working frequency band indication information issued by the network side or the extended multi-working band indication information one by one according to the above method. Whether one or more operating frequency bands determined by the frequency band indication information is a part of the operating frequency band supported by the terminal, if yes, the terminal sends the cell identity CellIdentity and the tracking area code TrackingAreaCode to the upper layer, if not, the terminal identifies the cell as forbidden.

发送模块用于发送工作频段对应的工作频段指示信息和扩展工作频段指示信息给终端。The sending module is used to send the working frequency band indication information corresponding to the working frequency band and the extended working frequency band indication information to the terminal.
本发明还提供了一种终端，包括接收模块和判断模块。The present invention also provides a terminal, including a receiving module and a judging module.
接收模块用于接收工作频段对应的工作频段指示信息和扩展工作频段指示信息。The receiving module is used for receiving the working frequency band indication information corresponding to the working frequency band and the extended working frequency band indication information.
判断模块用于判断工作频段指示信息是否特定值，并根据工作频段指示信息和扩展工作频段指示信息判断终端是否支持工作频段指示信息或扩展工作频段指示信息确定的工作频段。The judging module is used to judge whether the working frequency band indication information is a specific value, and judge whether the terminal supports the working frequency band determined by the working frequency band indication information or the extended working frequency band indication information according to the working frequency band indication information and the extended working frequency band indication information.
由于采用了工作频段指示信息和扩展工作频段指示信息指示工作频段，老版本的终端可以只根据原有的工作频段指示信息接入网络，新版本的终端可以根据工作频段指示信息的指示，并根据扩展工作频段指示信息获取扩展后工作频段的指示信息，接入网络，从而达到既扩展了工作频段，又实现了后向兼容的目的。Since the working frequency band indication information and the extended working frequency band indication information are used to indicate the working frequency band, the terminal of the old version can only access the network according to the original working frequency band indication information, and the new version of the terminal can use the indication of the working frequency band indication information and The indication information of the extended working frequency band acquires the indication information of the expanded working frequency band, and accesses the network, so as to achieve the purpose of extending the working frequency band and realizing backward compatibility.
