具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明提供一种小区接入方法。
参照图1，图1为本发明小区接入方法第一实施例的流程示意图。
本实施例提出一种小区接入方法，所述小区接入方法包括：
步骤S10，在接收到终端发送的小区接入请求时，基站确定所述终端对应的服务配置文件标识符SPID；
在本实施例中，优选根据终端对应的用户标识信息对终端进行分组以配置不同的SPID(Service Profile Identifier，服务配置文件标识符)，所述配置SPID的方式包括以下几种：a、根据终端对应的运营商标识信息进行配置，即先通过终端用户身份识别卡中预设的MNC(Mobile Network Code，移动网络号码)确定所述终端所归属的移动网络，如当所述MNC值为00或02时，确定所述终端用户属于中国移动的用户，则对中国移动的终端用户配置一个SPID。b、根据终端的唯一标识符，如IMEI(International Mobile Equipment Identity，移动设备国际身份码)或IMSI(Iinternational Mobile Subscriber Identity，国际移动用户识别码)对应的范围值进行分组，例如，将终端对应的IMEI号为1-1000的终端划分为一组，IMEI号为1001-2000的终端划分为另一组，并对每组终端用户配置一个SPID。例如，将移动用户的SPID值设置为1，联通用户的SPID值设置为2，电信用户的SPID值设置为3；或者将IMEI号为1-1000的终端用户对应的SPID值设置为4，1001-2000的终端用户对应的SPID值设置为5等等，则在获取到SPID值时，即可确定终端用户归属的类型。
在本实施例中，在接收到终端发送的小区接入请求时，核心网上报终端的SPID信息，然后基站获取所述终端对应的SPID，并根据获取的所述SPID识别出终端所归属的运营商类型或用户所属小组。
步骤S20，根据预设的SPID与小区标识的映射关系，所述基站获取确定的SPID对应的小区标识；
在本实施例中，优选为预设每个SPID值配置不同的小区标识，如SPID值为1的终端对应的小区标识包括5个，所述预设每个SPID值对应不同的小区标识的优选方案如下：基站在预设的后台数据库中配置各个SPID值对应的小区标识，也就是将各个SPID值的含义赋值为单个或多个小区标识信息或小区频点信息，例如将各个SPID值对应的小区设置为小区ID号或者小区频点信息等，当终端的SPID值对应的小区标识配置完成后，基站即可根据所述SPID值确定对应的小区ID或小区频点信息。本实施例具体过程如下：当基站接收到终端发送的小区接入请求时，基站获取终端的SPID值，先根据终端的SPID值来判断获取到的SPID值是否与基站预设的SPID值匹配，若不匹配，则基站不响应所述 小区接入请求，如果匹配则基站获取所述SPID对应的小区标识，并将所述SPID值对应的小区标识对应的小区作为待接入小区。
进一步地，为提高小区接入的准确性，所述SPID信息对应的小区标识信息优选包括小区的频段信息+频点信息，可以理解的是，网络频谱中包括多个频段的信息，各个频段对应的频点可能会重复，因此，本实施例中，可在后台数据库中配置SPID值对应各个小区标识信息时，所述小区标识信息包括频段信息+频点信息。如SPID值为84对应的小区包括有：频段band 38+频点2570的小区Q1、频段band 38+频点2600的小区Q2或频段band 41+频点2552的小区Q3，则所述用户类型信息SPID为84映射的小区包含3个小区，分别是Q1、Q2和Q3。
步骤S30，所述基站将所述终端接入到获取的所述小区标识对应的小区。
在本实施例中，获取的小区标识为多个小区标识时，则基站通过预设的方式选择其中一个小区标识对应的小区作为待接入小区，所述预设方式可根据终端发送的小区接入请求进行确定，如根据小区接入请求中对应的待接入小区标识信息进行确定，此时在下文实施例中进行详述。
本实施例提出的小区接入方法，基站根据终端对应的SPID，确定所述SPID对应的待接入小区，并根据终端的具体请求将其接入到确定的小区中，实现了根据不同SPID的终端确定不同的待接入小区，并根据终端的具体接入请求将其接入到对应的小区中，而不是在接收到各种不同类型终端的小区切入请求时，将不同类型的终端都接入到终端请求的小区中，使得小区的接入方式更加灵活。
进一步地，为提高小区接入的灵活性，基于第一实施例提出本发明小区接入方法的第二实施例，在本实施例中，参照图2，所述步骤S30包括：
步骤S31，基站确定所述小区接入请求中对应的待接入小区标识；
步骤S32，所述基站将所述待接入小区标识与获取的小区标识进行比对；
步骤S33，在所述待接入小区标识与获取的所述小区标识匹配时，所述基站将所述终端接入到获取的所述小区标识对应的小区。
在本实施例中，在接收到终端发送的小区接入请求时，先确定所述小区接入请求中对应的待接入小区标识(如待接入的小区ID或小区频点)，基站获取所述待接入小区标识，并将所述待接入小区标识与获取的小区对应的小区标识进行比对，在检测到所述小区标识与所述待接入小区标识相匹配时，基站即可将相匹配的小区作为目标小区，并将所述终端接入到所述目标小区中。进一步地，当所述小区接入请求中不包括待接入小区标识，此时，基站可按照预设的方式(如将默认的小区)选择待接入小区，或者，基站识别当前可作为待接入小区的负荷情况或网络制式优先级，将负荷较小的小区或制式优先级较高的小区作为待接入小区。
进一步地，为提高小区接入的灵活性，在本实施例中，参照图3，所述步骤S32之后， 所述步骤S30还包括：
步骤S34，在所述待接入小区标识与获取的所述小区标识不匹配时，基站发送获取的小区标识对应的小区频点给终端，以供终端根据获取的小区频点选择小区频点对应的小区中信号强度满足预设条件的小区并反馈小区接入请求；
在本实施例中，当终端发送的待接入小区标识与获取的所述小区标识不匹配时，说明此时终端要接入的小区不在基站预设的小区中，本实施例优选基站释放空口资源，并向终端发送重定向频点，也就是将基站预设的小区中对应的小区频点发送给终端，以供终端在基站发送的这些小区频点中选择一个小区频点作为待接入的小区频点。
步骤S35，在接收到终端反馈的小区接入请求时，所述基站将所述终端接入到信号强度满足预设条件的小区中。
在本实施例中，当基站接收到终端反馈的小区接入请求时，即可将所述信号强度满足预设条件的小区作为目标小区，并将所述终端接入到所述目标小区中。
进一步地，为提高小区接入的灵活性，基于第一实施例提出本发明小区接入方法的第三实施例，在本实施例中，参照图4，所述步骤S30之后，所述小区接入方法包括：
步骤S40，若终端接入成功，所述基站发送所述SPID对应的小区频点给终端，以供终端根据接收到的小区频点反馈接收到小区频点中信号强度大于预设阈值的小区对应的小区频点；
步骤S50，在接收到终端反馈的小区频点时，所述基站基于接收到的小区频点确定待切换小区；
在本实施例中，所述小区切换请求的触发方式为基站检测到终端接入后下发测量频点，并在终端发生移动时，所述终端检测频点下小区的信号是否满足预设阈值，若满足，终端将测量信息上报给基站，以发起小区切换请求。进一步地，终端上报的测量报告中携带的小区信号强度满足预设阈值，基站在接收到的小区中确定待切换小区，所述基站确定待切换小区的方式优选根据终端上报的小区，按照各个小区的制式优先级、信号强度、网络资源负荷量等因素进行排序，根据排序结果优选将第一个小区作为目标小区，并给所述目标小区发起切换请求，将终端的信息告诉目标小区，目标小区判断可以让终端切入后通知源基站，基站再给终端发送切换命令(协议中是一条重配消息)，通知终端切换到目标小区。当切换请求失败时，还可尝试向第二个小区发起切换请求，若失败，可依次类推向其它小区发起切换请求。
本发明实施例中，优选为基站根据对应的SPID值指定的小区ID或小区频点下发测量信息，使终端只能切换到预设小区中，所述测量信息携带终端待切换小区的频点，当终端接收到所述小区频点时，优选通过预设的应用(如信号测量仪)测量小区频点对应的小区信号，并计算测量的信号的强度，当终端计算出小区频点对应的信号强度大于预设阈值(如-80DB)，则将所述小区对应的小区频点发送给基站。进一步地，终端每次给基站上 报的测量报告中只能包含一个频点下的多个小区，如果终端测量出多个频点下的小区都满足预设阀值，则上报多个测量报告，这种情况下基站一般先收到哪个测量报告，就在哪个测量报告中的小区中选择切换的目标小区。
步骤S60，所述基站将所述终端切换到确定的所述小区。
在本实施例中，基站在接收到终端反馈的小区频点时，确定待切换的小区是否只包含一个小区，若是，则所述基站将所述终端切换到所述小区中，若不是，要根据各个小区对应的小区优先级，确定终端待切换的小区。本实施例中，所述切换场景包括S1切换(即基站与基站之间通过核心网进行切换)和X2切换(基站与基站之间的切换)。
进一步地，为提高小区接入的灵活性，基于第二实施例提出本发明小区接入方法的第三实施例，在本实施例中，若终端反馈的小区频点包括多个小区标识时，参照图5，所述步骤S50包括：
步骤S51，所述基站对接收到的各个小区标识对应的小区进行优先级排序；
步骤S52，所述基站将优先级高的小区作为待切换小区。
在本实施例中，所述基站可先在后台数据库中配置各个小区的优选级，所述配置优选级的方式包括：
1)方式一、定义所述SPID信息的参数，本领域技术人员可以理解的是，协议定义SPID有两组取值范围，一组取值范围是129～256，为协议定义的值，用于小区重选和切换，一组取值范围是1～128，由于SPID只能带一个值，无法同时使用两个SPID的功能，故此时可将预设的SPID的含义扩充，使得自定义协议SPID可包含协议定义SPID的功能。例如，协议定义SPID值为254时表示E-UTRAN制式优先级为低，UTRAN制式优先级为中，GERAN制式优先级为高，在本实施例中，优选在预设的SPID的后台配置表中增加参数，例如：将小区Q1的制式优选级设置为高、小区Q2的制式优选级设置为中，小区Q3的制式优选级设置为低，当终端发送的待切换小区标识信息对应的小区包括多个小区时，此时，基站根据各个小区预设的制式优先级，即可将优先级高的小区作为目标小区，并将所述终端切换至所述目标小区中。
进一步地，所述小区优选级还可根据小区当前的网络负载情况进行判断，如基站检测当前各个待切换小区的网络负荷情况，并将负荷情况较小的小区作为目标小区，将所述终端切换至所述目标小区中。
本发明进一步提供一种小区接入装置。
参照图6，图6为本发明小区接入装置第一实施例的功能模块示意图。
需要强调的是，对本领域的技术人员来说，图6所示功能模块图仅仅是一个较佳实施例的示例图，本领域的技术人员围绕图6所示的小区接入装置的功能模块，可轻易进行新的功能模块的补充；各功能模块的名称是自定义名称，仅用于辅助理解该小区接入装置的 各个程序功能块，不用于限定本发明的技术方案，本发明技术方案的核心是，各自定义名称的功能模块所要达成的功能。
本实施例提出一种小区接入装置，所述小区接入装置包括：
确定模块10，用于在接收到终端发送的小区接入请求时，确定所述终端对应的服务配置文件标识符SPID；
在本实施例中，优选根据终端对应的用户标识信息对终端进行分组以配置不同的服务配置文件标识符SPID，所述配置SPID的方式包括以下几种：a、根据终端对应的运营商标识信息进行配置，即所述确定模块10先通过终端用户身份识别卡中预设的MNC(Mobile Network Code，移动网络号码)确定所述终端所归属的移动网络，如当所述MNC值为00或02时，确定所述终端用户属于中国移动的用户，则对中国移动的终端用户配置一个SPID。b、根据终端的唯一标识符，如IMEI(International Mobile Equipment Identity，移动设备国际身份码)或IMSI(Iinternafional Mobile Subscriber Identity，国际移动用户识别码)对应的范围值进行分组，例如，将终端对应的IMEI号为1-1000的终端划分为一组，IMEI号为1001-2000的终端划分为另一组，并对每组终端用户配置一个SPID。例如，将移动用户的SPID值设置为1，联通用户的SPID值设置为2，电信用户的SPID值设置为3；或者将IMEI号为1-1000的终端用户对应的SPID值设置为4，1001-2000的终端用户对应的SPID值设置为5等等，则在获取到SPID值时，所述确定模块10即可确定终端用户归属的类型。
在本实施例中，在接收到终端发送的小区接入请求时，核心网上报终端的SPID信息，然后所述确定模块10获取所述终端对应的SPID，并根据获取的所述SPID识别出终端所归属的运营商类型或用户所属小组。
获取模块20，用于根据预设的SPID与小区标识的映射关系，获取确定的SPID对应的小区标识；
在本实施例中，优选为预设每个SPID值配置不同的小区标识，如SPID值为1的终端对应的小区标识包括5个，所述预设每个SPID值对应不同的小区标识的优选方案如下：基站在预设的后台数据库中配置各个SPID值对应的小区标识，也就是将各个SPID值的含义赋值为单个或多个小区标识信息或小区频点信息，例如将各个SPID值对应的小区设置为小区ID号或者小区频点信息等，当终端的SPID值对应的小区标识配置完成后，所述确定模块10即可根据所述SPID值确定对应的小区ID或小区频点信息。本实施例具体过程如下：当基站接收到终端发送的小区接入请求时，所述获取模块20获取终端的SPID值，先根据终端的SPID值来判断获取到的SPID值是否与基站预设的SPID值匹配，若不匹配，则基站不响应所述小区接入请求，如果匹配则基站获取所述SPID对应的小区标识，并将所述SPID值对应的小区标识对应的小区作为待接入小区。
进一步地，为提高小区接入的准确性，所述SPID信息对应的小区标识信息优选包括小区的频段信息+频点信息，可以理解的是，网络频谱中包括多个频段的信息，各个频段 对应的频点可能会重复，因此，本实施例中，可在后台数据库中配置SPID值对应各个小区标识信息时，所述小区标识信息包括频段信息+频点信息。如SPID值为84对应的小区包括有：频段band 38+频点2570的小区Q1、频段band 38+频点2600的小区Q2或频段band 41+频点2552的小区Q3，则所述用户类型信息SPID为84映射的小区包含3个小区，分别是Q1、Q2和Q3。
接入模块30，用于将所述终端接入到获取的所述小区标识对应的小区。
在本实施例中，获取的小区标识为多个小区标识时，则所述接入模块30通过预设的方式选择其中一个小区标识对应的小区作为待接入小区，所述预设方式可根据终端发送的小区接入请求进行确定，如根据小区接入请求中对应的待接入小区标识信息进行确定，此时在下文实施例中进行详述。
本实施例提出的小区接入装置，基站根据终端对应的SPID，确定所述SPID对应的待接入小区，并根据终端的具体请求将其接入到确定的小区中，实现了根据不同SPID的终端确定不同的待接入小区，并根据终端的具体接入请求将其接入到对应的小区中，而不是在接收到各种不同类型终端的小区切入请求时，将不同类型的终端都接入到终端请求的小区中，使得小区的接入方式更加灵活。
进一步地，为提高小区接入的灵活性，基于第一实施例提出本发明小区接入装置的第二实施例，在本实施例中，参照图7，所述接入模块30包括：
确定单元31，用于确定所述小区接入请求中对应的待接入小区标识；
比对单元32，用于将所述待接入小区标识与获取的小区标识进行比对；
第一接入单元33，用于在所述待接入小区标识与获取的所述小区标识匹配时，将所述终端接入到获取的所述小区标识对应的小区。
在本实施例中，在接收到终端发送的小区接入请求时，所述确定单元31先确定所述小区接入请求中对应的待接入小区标识(如待接入的小区ID或小区频点)，基站获取所述待接入小区标识，所述比对单元32将所述待接入小区标识与获取的小区对应的小区标识进行比对，在检测到所述小区标识与所述待接入小区标识相匹配时，所述第一接入单元33即可将相匹配的小区作为目标小区，并将所述终端接入到所述目标小区中。进一步地，当所述小区接入请求中不包括待接入小区标识，此时，可按照预设的方式(如将默认的小区)选择待接入小区，或者，先识别当前可作为待接入小区的负荷情况或网络制式优先级，将负荷较小的小区或制式优先级较高的小区作为待接入小区。
进一步地，为提高小区接入的灵活性，参照图8，在本实施例中，所述接入模块30还包括：
发送单元34，用于在所述待接入小区标识与获取的所述小区标识不匹配时，发送获取的小区标识对应的小区频点给终端，以供终端根据获取的小区频点选择小区频点对应的小区中信号强度满足预设条件的小区并反馈小区接入请求；
在本实施例中，当终端发送的待接入小区标识与获取的所述小区标识不匹配时，说明此时终端要接入的小区不在基站预设的小区中，本实施例优选所述发送单元34释放空口资源，并向终端发送重定向频点，也就是将预设的小区中对应的小区频点发送给终端，以供终端在所述发送单元34发送的这些小区频点中选择一个小区频点作为待接入的小区频点。
第二接入单元35，用于在接收到终端反馈的小区接入请求时，将所述终端接入到信号强度满足预设条件的小区中。
在本实施例中，当接收到终端反馈的小区接入请求时，所述第二接入单元35即可将所述信号强度满足预设条件的小区作为目标小区，并将所述终端接入到所述目标小区中。
进一步地，为提高小区接入的灵活性，基于第一实施例提出本发明小区接入装置的第二实施例，在本实施例中，参照图8，所述小区接入装置还包括：
发送模块40，用于若终端接入成功，发送所述SPID对应的小区频点给终端，以供终端根据接收到的小区频点反馈接收到小区频点中信号强度大于预设阈值的小区对应的小区频点；
所述确定模块10，还用于在接收到终端反馈的小区频点时，基于接收到的小区频点确定待切换小区；
在本实施例中，所述小区切换请求的触发方式为检测到终端接入后下发测量频点，并在终端发生移动时，所述终端检测频点下小区的信号是否满足预设阈值，若满足，终端将测量信息上报给基站，以发起小区切换请求。进一步地，终端上报的测量报告中携带的小区信号强度满足预设阈值，所述确定模块10在接收到的小区中确定待切换小区，所述确定模块10确定待切换小区的方式优选根据终端上报的小区，按照各个小区的制式优先级、信号强度、网络资源负荷量等因素进行排序，根据排序结果优选将第一个小区作为目标小区，并且发送模块40给所述给目标小区发起切换请求，将终端的信息告诉目标小区，目标小区判断可以让终端切入后通知源基站，所述发送模块40再给终端发送切换命令(协议中是一条重配消息)，通知终端切换到目标小区。当切换请求失败时，还可尝试向第二个小区发起切换请求，若失败，可依次类推向其它小区发起切换请求。
本发明实施例中，优选为所述发送模块40根据对应的SPID值指定的小区ID或小区频点下发测量信息，使终端只能切换到预设小区中，所述测量信息携带终端待切换小区的频点，当终端接收到所述小区频点时，优选通过预设的应用(如信号测量仪)测量小区频点对应的小区信号，并计算测量的信号的强度，当终端计算出小区频点对应的信号强度大于预设阈值(如-80DB)，则将所述小区对应的小区频点发送给所述确定模块10。终端每次给所述确定模块10上报的测量报告中只能包含一个频点下的多个小区，如果终端测量出多个频点下的小区都满足预设阀值，则上报多个测量报告，这种情况下所述确定模块10一般先收到哪个测量报告，就在哪个测量报告中的小区中选择切换的目标小区。
切换模块50，用于将所述终端切换到确定的所述小区。
在本实施例中，所述确定模块10在接收到终端反馈的小区频点时，确定待切换的小区是否只包含一个小区，若是，则所述切换模块50将所述终端切换到所述小区中，若不是，要根据各个小区对应的小区优先级，确定终端待切换的小区。本实施例中，所述切换场景包括S1切换(即基站与基站之间通过核心网进行切换)和X2切换(基站与基站之间的切换)。
进一步地，为提高小区接入的灵活性，基于第二实施例提出本发明小区接入装置的第三实施例，在本实施例中，参照图10，若终端反馈的小区频点包括多个小区标识时，所述确定模块10包括：
排序单元11，用于对接收到的各个小区标识对应的小区进行优先级排序；
处理单元12，用于将优先级高的小区作为待切换小区。
在本实施例中，所述基站可先在后台数据库中配置各个小区的优选级，所述配置优选级的方式包括：
1)方式一、定义所述SPID信息的参数，本领域技术人员可以理解的是，协议定义SPID有两组取值范围，一组取值范围是129～256，为协议定义的值，用于小区重选和切换，一组取值范围是1～128，由于SPID只能带一个值，无法同时使用两个SPID的功能，故此时可将预设的SPID的含义扩充，使得自定义协议SPID可包含协议定义SPID的功能。例如，协议定义SPID值为254时表示E-UTRAN制式优先级为低，UTRAN制式优先级为中，GERAN制式优先级为高，在本实施例中，优选在预设的SPID的后台配置表中增加参数，例如：将小区Q1的制式优选级设置为高、小区Q2的制式优选级设置为中，小区Q3的制式优选级设置为低，当终端发送的待切换小区标识信息对应的小区包括多个小区时，此时，所述判断单元11根据各个小区预设的制式优先级，所述处理单元12即可将优先级高的小区作为目标小区，并且所述切换模块50将所述终端切换至所述目标小区中。
进一步地，所述小区优选级还可根据小区当前的网络负载情况进行判断，如检测当前各个待切换小区的网络负荷情况，所述处理单元12将负荷情况较小的小区作为目标小区，所述切换模块50将所述终端切换至所述目标小区中。
为提高小区接入的灵活性，本发明的实施例还提出一种非易失性计算机可读存储介质，其中存储有指令，所述指令在由基站的处理器执行时使所述基站实施一种小区接入方法，所述小区接入方法包括以下步骤：
在接收到终端发送的小区接入请求时，基站确定所述终端对应的服务配置文件标识符SPID；
根据预设的SPID与小区标识的映射关系，所述基站获取确定的SPID对应的小区标识；
所述基站将所述终端接入到获取的所述小区标识对应的小区。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其它变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者系统不仅包括那些要素，而且还包括没有明确列出的其它要素，或者是还包括为这种过程、方法、物品或者系统所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者系统中还存在另外的相同要素。
上述本发明实施例序号仅仅为了描述，不代表实施例的优劣。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本发明各个实施例所述的方法。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其它相关的技术领域，均同理包括在本发明的专利保护范围内。
