  • the present invention relates to call technology in communication technology, and more particularly, to an incoming call access method. Background of the invention
  • terminal equipment such as fixed phones and mobile phones
  • terminal equipment has brought great convenience to people's work and life. People can use these terminal equipment to communicate with the outside world at any time. However, these terminal devices will also cause users some trouble. For example, users hope that they will not be disturbed by unimportant calls at night or during other breaks, but at the same time they will not lose important calls. In fact, during this time, there are often some irrelevant calls, some even harassing calls.
  • the user can turn off the terminal device and turn it on again when needed.
  • the terminal device since the terminal device includes a fixed terminal and a mobile terminal, the mobile terminal is relatively easy to shut down, and for a fixed phone, if the user wants to shut down, he can only cut off the telephone line. It is very inconvenient. Regardless of whether it is a mobile terminal or a fixed terminal, shutting down the terminal device will bring other problems: Once the terminal device is turned off, the user cannot receive any calls. In this way, even if someone has very important things, they cannot contact the user through the terminal device. In addition, this solution requires the user to turn on the terminal device again when it is needed.
  • a mobile terminal For a mobile terminal that is carried around, it is very convenient to switch on and off, and for a fixed terminal, the user often forgets to turn on the device. If the user forgets to turn on the device after the terminal device is turned off, the user cannot receive calls from other users through the terminal device. Users can also use the secretary desk service provided by current mobile communication systems, but this service is currently limited to mobile terminals. For a user using a mobile terminal, it can be set through the secretary desk. For example, if the user does not want to be disturbed by the phone at present, the secretary desk can be requested to leave a message to the calling user who is currently calling and send the message to himself.
  • the secretary desk when the secretary desk receives an incoming call for the user, it asks the calling user to leave a message, and then informs the user through a short message or the like.
  • the user learns the calling party's message by dialing the secretary desk phone. The user can decide whether to call back according to the message of the calling user, which ensures that the user can not be disturbed by the incoming call.
  • the secretary desk service is a paid service, users who use the service need to pay some fees.
  • the secretary desk changed the caller's incoming call to a short message or other methods to notify the called user. Although the user will not receive the incoming call, they will still receive the short message or other information. Basically solve the problem of users being disturbed.
  • the short message sent by the secretary desk to the called user may be delayed or lost, or the user does not read the short message in time, for example, due to the non-timeliness of short message communication, and the general user sets the short message prompt tone. It is soft, weak, and even does not set a prompt tone, which makes users often unable to process short messages in a timely manner, and therefore cannot handle some urgent matters in a timely manner.
  • the white list scheme is to set in advance a calling number that can access the called terminal in the white list.
  • the white list function When the called terminal starts the white list function, only these calling numbers in the white list can be accessed by the called party. Call the terminal.
  • this solution limits the calling numbers that can be accessed. If a user A has an urgent need to talk to user C, but it cannot use the whitelisted The number is used as the calling number to call the called user C.
  • the blacklist scheme is to set a calling number that denies access to the called terminal in advance in the blacklist.
  • the called terminal activates the blacklist function and the called terminal connects the call, it is determined that the calling number is in the blacklist and the call is rejected.
  • This solution cannot prevent others from dialing the called user by using a telephone other than the blacklist. For example, a situation where a harassing user uses a public telephone to harass a called user cannot be avoided through a blacklist.

Description

一种来话接入方法 技术领域
本发明涉及通信技术中的呼叫技术, 更确切地说是涉及一种来话接 入方法。 发明背景
随着诸如固定电话、 手机等终端设备的普及, 终端设备给人们的工 作和生活带来了极大的方便, 人们可以随时使用这些终端设备与外界通 信。 但是, 这些终端设备也会为用户带来一定的麻烦。 比如, 用户希望 在夜间或其他的休息时间内不会被不重要的来电打扰, 但同时又不会丟 失重要来电。 可实际上, 在这段时间内往往会有一些无关紧要的电话, 有些甚至是骚扰电话。
为了避免被来电打扰, 用户可以关掉终端设备, 并在需要使用时再 重新开启终端设备。 对于这种关闭终端设备的方案来说, 由于终端设备 包括固定终端和移动终端, 移动终端比较容易关机, 而对于固定电话来 说, 如果要想关机, 目前只能是切断电话线, 这对于用户来说非常不方 便。 而不管是移动终端还是固定终端, 关闭终端设备都会带来另一些问 题: 一旦终端设备关机, 用户就无法接听到任何电话。 这样, 别人即使 有非常重要的事情也无法通过该终端设备与用户取得联系。 还有, 该方 案需要用户在需要使用时重新开启终端设备, 对于随身携带的移动终端 来说, 开关机非常方便, 而对于固定终端来说, 用户往往会忘记开机。 而如果用户在关闭终端设备后忘记开机, 则用户就无法通过该终端设备 接听到其他用户的电话。 用户也可以使用目前的移动通信系统所提供的秘书台业务, 但是这 种业务目前仅局限于移动终端。 对于使用移动终端的用户来说, 可以通 过秘书台进行设置, 比如, 用户当前不希望被电话打扰, 则可以要求秘 书台对当前来话的主叫用户进行留言, 并将该留言发送给自己。 这样, 秘书台在接到针对该用户的来话时, 即要求主叫用户留言, 然后通过短 消息等方式通知该用户, 该用户通过拨打秘书台电话得知主叫用户的留 言。 该用户则可以根据主叫用户的留言来决定是否回电话, 这就保证了 该用户可以不会被来电打扰。
但是, 由于秘书台业务是付费业务, 因此使用该业务的用户需要支 付一些费用。 而秘书台是将主叫的来电改为短消息或其他的方式通知被 叫用户的, 虽然用户不会接到来电, 但是还是会接到短消息或其他的信 息, 因此这种方案并没有从根本上解决用户被打扰的问题。 而且秘书台 发送给被叫用户的短消息等可能会出现延迟甚至丢失 , 或者用户没有及 时阅读短消息, 比如, 由于短消息通信的非及时性, 以及一般用户将短 消息的提示音设置得很柔和、 也很弱, 甚至不设置提示音等原因, 使得 用户往往不能及时处理短消息, 因此而不能及时处理一些紧急事务。
还有一种来话筛选方案, 比如主叫黑名单和白名单的方案可以用于 解决用户希望不会被不重要的来电打扰, 但同时又不会丢失重要来电的 问题。 具体来说, 白名单方案是在白名单中预先设置能够接入被叫终端 的主叫号码, 在被叫终端启动白名单功能时, 只有白名单中的这些主叫 号码才能被接入到被叫终端。 该方案虽然可以在很大程度上解决上述问 题, 但是, 该方案限定了能够接入的主叫号码, 如果某个用户 A有急事 需要与用户 C通话,但又无法采用设置在白名单中的号码作为主叫号码 呼叫被叫用户 C, 比如, 白名单中有用户 A手机号码, 而此时, 用户 A 因手机没电而想通过用户 B的手机联系被叫用户 C时, 却因为用户 B 的手机号码不在白名单中而无法与该被叫用户 C联系。黑名单方案是在 黑名单中预先设置拒绝接入被叫终端的主叫号码, 在被叫终端启动黑名 单功能并且被叫终端接续呼叫时, 判断主叫号码在黑名单中, 拒绝接续 呼叫。 该方案无法防止别人用黑名单以外的电'话拨打被叫用户。 比如, —个騒扰用户使用一个公共电话騒扰某被叫用户等情况就不能通过黑 名单方式来避免。 另外, 黑白名单的维护都比较繁琐。 发明内容

图 1为本发明方案一种实施例的实现流程图;
图 2为本发明方案另一种实施例的实现流程图。 实施本发明的方式
本发明方案主要是在被叫终端设置接入呼叫标记, 被叫终端在收到 主叫发起的呼叫时, 判断该呼叫中是否包含自身的接入 叫标记, 如果 是, 则按照该呼叫的正常流程处理; 否则, 对该呼叫作中止处理。 本发 明所述按照该呼叫的正常流程处理就是采用现有技术接续该呼叫 , 通知 使用被叫终端的用户接收该呼叫, 如用振铃通知。
本发明方案具体来说, 设置接入呼叫标记有两种方式, 相应地, 被 叫终端有两种处理方式。 一种方式为: 将主叫号码作为接入呼叫标记; 另一种方式为: 设置接入码, 并将该接入码作为接入呼叫标记。 对于第 一种处理方式来说, 该方式主要是通过在被叫终端中设置识别登记请求 的功能、 接入码及主叫号码登记表, 使得主叫用户可以通过带有接入码 的登记请求将自身的主叫号码存入主叫号码登记表, 以此将该主叫号码 作为接入呼叫标记,之后,主叫用户在通过该主叫号码呼叫被叫终端时, 被叫终端可以通过判断主叫号码登记表中是否存有该主叫号码, 也即接 入呼叫标记来确定是否按正常流程处理当前呼叫。 对于第二种处理方式 来说, 该方式主要是在被叫终端中设置接入码, 并将该接入码作为接入 呼叫标记, 主叫用户在呼叫被叫终端时, 被叫终端可以通过判断该呼叫 是否存储有该接入码来确定是否按照正常流程进行处理。
下面结合附图对这两种方式分别进行说明。
对于第一种方式来说, 设置接入呼叫标记主要是通过设置识别登记 请求的功能, 并由被叫用户在被叫终端中设置接入码及主叫号码登记 表, 被叫终端在收到主叫发起的呼叫时, 如果该呼叫为登记请求, 则从 该呼叫中获取需要登记的主叫号码, 并将该主叫号码保存在设置的主叫 号码登记表中, 从而在被叫终端中保存了被叫用户允许接入的主叫号 码, 也即, 在被叫终端中保存了接入呼叫标记。 通过这样的设置, 如果 该呼叫不是登记请求, 则被叫终端在确定自身的主叫号码登记表中含有 该呼叫对应的主叫号码, 也即含有相 的接入呼叫标记时, 按该呼叫的 正常流程处理该呼叫。
第一种方式的实现过程参见图 1 , 具体可以通过以下步驟实现: 步骤 101、 预先在被叫终端设置识别用于登记主叫号码的登记请求 的功能。
该登记请求可以设置为短消息、 多媒体短消息、 用户到用户信令
( UUS, User-to-User Signaling )或语音呼叫。
识别登记请求的功能可以设置为: 被叫终端接收到的呼叫为短消息 或者多媒体短消息, 则识别该呼叫为登记请求; 或者被叫终端接收到的 呼叫携带登记请求标识, 则识别该呼叫为登记请求。
步驟 102、 在被叫终端中设置接入码及主叫号码登记表。
通常, 接入码由被叫用户设置。 被叫用户在设置接入码之后, 即可 将该接入码告诉自己的亲朋好友等, 以便这些人能够根据该接入码随时 与自己联系。 所设置的主叫号码登记表用于保存主叫号码。
步骤 103、 主叫用户向被叫终端发起呼叫。
步骤 104、 被叫终端在收到呼叫时, 首先判断该呼叫是否为登记请 求, 如果是, 则进入步骤 105; 否则, 进入步骤 108。
由于本发明在步骤 101中设置了识别登记请求的功能, 所以就可以 根据接收到的呼叫类型判定该呼叫是否为登记请求。
步骤 105、 被叫终端判断该登记奇求中是否包含了被叫终端设置的 接入码, 如果是, 转入步骤 106; 否则, 转入步骤 107。 拒绝登记, 并 结束本处理流程。
如果登记请求是一个短消息, 则接入码和主叫号码可以包含在短消 息内容中。 当然, 如果要登记的主叫号码为当前呼叫的主叫号码, 则该 主叫号码也可以通过主叫号码识别方式传送到被叫终端, 此时, 登记请 求的短消息中仅仅需要包含接入码。
步骤 106、 被叫终端从呼叫中提取主叫号码, 并将该主叫号码保存 在主叫号码登记表中。
步骤 107、 被叫终端拒绝登记, 并结束本处理流程。
步驟 108、 被叫终端判断该呼叫对应的主叫号码是否保存在自身的 主叫号码登记表中, 如果是, 转入步骤 109; 否则, 转入步骤 110。
步骤 109、 被叫终端按该呼叫的正常流程进行处理。
步骤 110、 被叫终端对该呼叫作中止处理, 并结束本处理流程。 由于主叫发起的呼叫可能是短消息、 多媒体短消息、 UUS或语音呼 叫, 因此, 被叫终端在对当前呼叫作中止处理时, 对于短消息、 多媒体 短消息以及 UUS来说, 为删除当前接收到的信息; 对于语音呼叫来说, 则为拒绝接续当前呼叫。
另外, 对于登记请求为短消息的情况来说, 具体可以是在短消息中 设置特殊的标识, 将该标识称为登记请求标识。 这样, 被叫终端在收到 呼叫时, 首先判断该呼叫是否为短消息, 如果为短消息, 则进一步判断 该短消息中是否有该登记请求标识, 如果有, 则确定该短消息为登记请 求, 否则, 确定该短消息不是登记请求。 当然, 针对登记请求为短消息 的情况, 也可以将被叫终端设置为: 在确定当前呼叫为短消息后, 即认 为该呼叫为登记请求。 这样, 在执行上述步驟 105的判断时, 如果该登 记请求中没有被叫设置的接入码, 则被叫终端可以在拒绝登记后, 按照 步骤 108 ~步骤 110所述的方法进行处理。
如果登记请求为语音呼叫, 则其可以通过将双音多频信号转换为数 字信号来实现登记消息的传送。
不管采用的是哪种登记请求方式, 如果要登记的主叫号码为当前主 叫的号码, 都可以将该需要登记的主叫号码通过主叫号码识别方式传送 到被叫终端。 对于那些要登记的主叫号码不是当前呼叫的主叫号码的情 况来说, 如果登记请求为短消息, 而一个固定终端无法发送短消息, 此 时, 主叫可以使用一个能够发送短消息的移动终端将固定终端的号码登 记到被叫终端的主叫号码簦记表中, 从而使得由该固定终端发起的呼叫 可以接入到被叫终端。
通过上述步骤, 即可实现本发明的目的。
在本发明方案中, 还可以进一步设置用于保存能够向本被叫终端发 起呼叫的主叫号码信息的白名单, 也就是说, 被叫用户可以在自身的终 端中设置白名单, 其他用户使用该白名单中的号码作为主叫号码发起的 呼叫能够被接入到该被叫终端。 通过这样的设置, 上述步骤 104中, 被 叫终端在判断该呼叫是否为登记请求之前, 可以先判 #该呼叫对应的主 叫号码是否已经保存在白名单中了, 如果已经保存了, 则被叫终端可以 通过查询白名单来确定可以接续当前呼叫, 也就是说, 没有必要将该主 叫号码再保存在主叫号码登记表中, 因此,在确定该呼叫为登记请求时, 可以拒绝将该主叫号码保存在主叫号码登记表中, 比如可以直接中止对 该呼叫的处理。 当然,也可以在被叫终端确定当前呼叫为登记请求之后, 且在判断该登记请求中是否包含了被叫设置的接入码之前, 也即在步驟 104和 105之间, 判断白名单中是否保存了当前呼叫对应的主叫号码, 如果保存了, 则直接拒绝登记, 并结束当前的处理流程。
所以说, 在设置有白名单的情况下, 白名单中的主叫号码都不会保 存在主叫号码登记表中。 而上述步驟 108中, 被叫终端在对主叫号码登 记表进行查询后, 如果该登记表中没有当前呼叫对应的主叫号码, 则对 该呼叫作中止处理。 因此, 在设置了白名单后, 被叫终端不但需要查询 主叫号码登记表中是否存有当前呼叫对应的主叫号码, 还应查询白名单 中是否存有该主叫号码, 只要主叫号码登记表和白名单中任意一个存有 该主叫号码, 就可以接续该主叫号码所对应的呼叫。 当然, 实际当中, 也可以将白名羊和主叫号码登记表合并为一个表使用。
在本发明方案中 , 还可以进一步设置用于保存不能向本被叫终端发 起呼叫的主叫号码信息的黑名单, 也就是说, 被叫用户可以在自身的终 端中设置黑名单, 这样, 其他用户在以该黑名单中的号码作为主叫号码 向该被叫终端发起呼叫时, 被叫终端会拒绝接入该呼叫。 通过这样的设 置, 被叫终端在收到呼叫时, 可以首先判断该呼叫所对应的主叫号码是 否保存在黑名单中, 如果是, 则不用再故后续的处理了, 可以直接结束 当前的处理流程。 也就是说, 上迷步骤 104中, 被叫终端在判断该呼叫 是否为登记请求之前, 应先判断该呼叫所对应的主叫号码是否保存在黑 名单中了,如果已经保存了,则直接执行对当前呼叫作中止处理的步骤; 如果没有保存, 则执行判断等后续步骤。
针对设置黑名单的情况来说, 还有一种处理方法是: 被叫终端在判 断该登记请求中是否包含了预先设置的接入码之前,也即步骤 105之前, 先判断该呼叫所对应的主叫号码是否保存在黑名单中, 如果是, 则不将 该主叫号码存入主叫号码登记表; 否则, 再执行后续处理。
事实上,本发明方案还可以在被叫终端中同时设置白名单和黑名单, 这样, 如果白名单中已经存有某个主叫号码, 则被叫终端可以直接接续 该主叫号码对应的呼叫; 如果黑名单中已经存有某个主叫号码, 则被叫 终端就不能将该主叫号码保存在自身的主叫号码登记表中。
如上所述, 在执行上述步骤时, 还应根据黑名单和白名单作相应的 判断。具体可以是先对黑名单进行判断,也可以是先对白名单进行判断。 下面以先对黑名单进行判断为例进行说明。
在设有黑名单的情况下,可以在被叫终端收到呼叫后,也即步骤 104 之前, 判断该呼叫对应的主叫号码是否保存在黑名单中, 如果保存在黑 名单中, 则直接结束当前处理流程; 如果没有保存在黑名单中, 则进一 步判断是否保存在白名单中。 在根据白名单进行判断时, 可以是在被叫 终端判断该呼叫是否为登记请求之前, 判断该呼叫对应的主叫号码是否 已经保存在白名单中了, 如果已经保存了, 则在确定该呼叫为登记请求 时, 拒绝将该主叫号码保存在主叫号码登记表中; 如果没有保存, 则按 照图 1所示的流程执行后续处理。 当然, 在根据白名单进行判断时, 也 可以在被叫终端确定当前呼叫为登记请求之后, 且在判断该登记请求中 是否包含了被叫设置的接入码之前, 也即在步骤 104和 105之间, 判断 白名单中是否保存了当前呼叫对应的主叫号码, 如果保存了, 则直接拒 绝登记, 并结束当前的处理流程; 如果没有保存, 则同样按照图 4所示 的流程执行后续处理。 '
当然, 也可以在被叫终端确定当前呼叫为登记请求之后, 且在判断 登记请求中是否包含被叫设置的接入码之前, 也即在步骤 104和 105之 间, 进一步判断该呼叫所对应的主叫号码是否已经保存在白名单或黑名 单中了, 如果已经保存了, 则可以直接结束当前处理流程; 如果被叫终 端确定白名单和黑名单中都没有该接入码, 则继续执行后续的处理。
对于同时设置了白名单和黑名单的情况来说, 如果当前呼叫不是登 记请求, 则上述步骤 110中, 在对当前呼叫作中止处理之前, 被叫终端 还应该判断该呼叫对应的主叫号码是否保存在白名单中, 如果是, 则按 该呼叫的正常流程进行处理; 否则, 对当前呼叫做中止处理。
本发明方案中, 可以是将主叫号码信息只保存在被叫终端的主叫号 码登记表、 白名单或黑名单中的任意一个表中。 具体来说, 如果被叫终 端中设置了白名单和 /或黑名单, 在这种情况下,被叫用户在将某个主叫 号码设置在被叫终端的白名单或黑名单中后, 被叫终端应该判断该主叫 号码登记表中是否保存了该主叫号码, 如果保存了, 则从该主叫号码登 记表中删除该主叫号码。 如果被叫用户在黑名单中设置了一个主叫号 码, 则被叫终端应检查白名单中是否存有该主叫号码, 如果是, 则删除 在白名单中的该主叫号码。 如果被叫用户在白名单中设置了一个主叫号 码, 则被叫终端应检查黑名单中是否存有该主叫号码, 如果是, 则删除 在黑名单的该主叫号码。
以上所述为针对第一种方式, 即设置主叫号码作为接入呼叫标记的 情况, 下面对第二种方式进行详细说明。
第二种方式的实现过程参见图 2, 具体通过以下步骤实现: 步骤 201、 预先在被叫终端中设置接入码。
实际当中, 接入码由被叫用户设置。 被叫用户在设置接入码之后, 即可将该接入码告诉自己的亲朋好友等, 以便这些人能够根据该接入码 随时与自己联系。
步骤 202、 主叫用户向被叫终端发起呼叫。
主叫发起的呼叫可能是短消息、多媒体短消息、 UUS或语音呼叫等。 如果主叫发起的呼叫为短消息、 多媒体短消息或 UUS, 则可以在这些信 息的内容中写入接入码, 比如, 设置" ,,作为接入码的开始标识, 其后 的信息为接入码。
步驟 203 ~ 205、 被叫终端在收到呼叫时, 判断该呼叫是否包含了自 身的接入码, 如果是, 则按照该呼叫的正常流程进行处理; 否则, 对该 呼叫作中止处理, 并结束本处理流程。
由于主叫发起的呼叫可能是短消息、 多媒体短消息、 UUS或语音呼 叫, 因此, 被叫终端在对当前呼叫作中止处理时, 与上述第一种方式相 同, 也就是说, 对于短消息、 多媒体短消息以及 UUS 来说, 为删除当 前接收到的信息; 对于语音呼叫来说, 则为拒绝接续或终止当前呼叫。
如果该呼叫是短消息、 多媒体短消息或 UUS, 则被叫终端可以根据 前面设置的标识" *# "来判断当前呼叫是否有接入码。
如果该呼叫是语音呼叫, 则被叫终端可以在收到该呼叫后, 首先接 续或接通该呼叫, 并自动播放提示主叫输入接入码的提示音, 当然, 这 里需要在被叫终端中预先设置播放音, 如果被叫在设定的时间内没有接 收到主叫输入的接入码, 则认为该次呼叫没有包含接入码; 否则, 确定 该次呼叫包含了接入码。 这里, 按照该呼叫的正常流程进行处理是指被 叫终端提示被叫有一个来话, 具体可以通过简单的振铃等进行提示。 对 该呼叫作中止处理则是指直接终止该次呼叫或通话。 如果接入码是通过其它的呼叫信息传送, 则被叫终端可以直接通过 呼叫携带的信息来判断是否包含了自身的接入码, 并根据判断结果来决 定是否接续呼叫或拒绝接续呼叫。 相应地, 按照该呼叫的正常流程进行 处理是指被叫终端接续呼叫, 并提示被叫有一个来话, 具体同样可以是 通过简单的振铃来提示。 对该呼叫作中止处理是指直接拒绝接续该次呼 叫。
实际当中, 在该呼叫是语音呼叫的情况下, 被叫终端提示主叫输入 接入码时,主叫可以通过双音多频信号( DTMF )、频移键控信号( FSK )、 信令或语音将接入码发送到通信网络。 被叫终端也可以通过上述四种方 式从通信网络接收接入码。 如果被叫终端具有接收主叫所发送的语音呼 叫的功能, 则被叫终端可以直接接收, 否则, 需要通信网络将该主叫发 送的语音呼叫转换为被叫终端可以接收的模式, 再将转换后的呼叫信息 发送给被叫终端。
下面以主叫通过 DTMF信号发送接入码为例,对其传输过程进行详 细说明。具体来说, 主叫可以是通过 DTMF信号将接入码通过通信网络 传送出去, 通信网络中的被叫交换机在收到该 DTMF信号后, 判断该被 叫终端是否具有将 DTMF信号转换为数字信号的功能, 如果有, 则直接 将该 DTMF信号发送给被叫终端, 由被叫终端将收到的 DTMF信号转 换为数字信号的接入码。如果被叫终端没有将 DTMF信号转换为数字信 号的功能,则该被叫交换机将该 DTMF信号转换为被叫终端能够识别的 模式, 之后再将转换后的信息发送给被叫终端, 被叫终端再根据该模式 进行数字信号的转换。
实际当中, 这里由被叫交换机进行的将该 DTMF信号转换为被叫终 端能够识别的模式的处理, 也可以由主叫交换机来完成。 比如, 固定终 端通过 DTMF信号向移动终端发送的接入码,可以直接由主叫交换机转 换为数字信号, 之后, 通信网络即可通过该数字信号将接入码传送给被 叫终端。
对于通过语音方式传送接入码的情况来说, 如果被叫终端支持语音 识别功能, 则被叫终端可以提示主叫通过语音方式输入接入码, 被叫终 端在接收到语音信息后, 即可通过语音识别得到主叫输入的接入码。
对于其他几种方式来说, 其处理过程类似, 因此不再赘述。
当然, 在获取了接入码之后, 被叫终端还需要进一步判断该接入码 是否为自身的接入码。
与上述第一种方式类似,还可以在被叫终端中设置白名单或黑名单, 也可以同时设置白名单和黑名单。
对于设置白名单的情况来说, 被叫终端在收到主叫发起的呼叫时, 首先应判断与该呼叫对应的主叫号码是否保存在白名单中, 如果是, 则 直接按照正常流程处理该呼叫; 否则, 再执行上述步驟 203中的判断过 程。
对于设置黑名单的情况来说, 被叫终端在收到主叫发起的呼叫时, 首先应判断与该呼叫对应的主叫号码是否保存在黑名单中, 如果是, 则 直接对该呼叫作中止处理; 否则, 再执行上述步骤 203中的判断过程。
对于同时设置有白名单和黑名单的情况来说, 则被叫终端可以首先 判断该呼叫对应的主叫号码是否保存在黑名单中, 如果黑名单中存有该 主叫号码, 则直接对该呼叫作中止处理; 否则, 再判断该主叫号码是否 保存在白名单中, 如果白名单中存有该主叫号码, 则直接按照正常流程 处理该呼叫, 如果既没有保存在黑名单中, 也没有保存在白名单中, 则 再执行上述步骤 203中的判断过程。
当然, 对于同时设置了白名单和黑名单的情况来说, 也可以先才艮据 白名单进行判断, 如果白名单中存有该呼叫对应的主叫号码, 则直接按 照正常流程处理该呼叫; 否则, 再判断黑名单中是否存有该主叫号码, 如果黑名单中存有该主叫号码, 则直接对该呼叫作中止处理, 如果既没 有保存在白名单中, 也没有保存在黑名单中, 则再执行上述步骤 203中 的判断过程。
对于同时设置有白名单和黑名单的方案来说, 如果被叫用户在黑名 单中设置了一个主叫号码, 则被叫终端应检查白名单中是否存有该主叫 号码, 如果是, 则删除在白名单中的该主叫号码。 如果被叫用户在白名 单中设置了一个主叫号码, 则被叫终端应检查黑名单中是否存有该主叫 号码, 如果是, 则删除在黑名单中的该主叫号码。
显然,本发明所涉及的主叫及被叫终端可以是移动终端、 固定终端、 个人数字助理(PDA )及便携机, 还可以是其他具有通信功能的终端。
以上所述仅为本发明方案的较佳实施例, 并不用以限定本发明的保 护范围。
