图 1示出了根据本发明实施例的控制 PDP上下文下发的方法 100的示 意性流程图。 如图 1所示, 该方法 100包括:
S110, 接收 SGSN发送的用户的 GPRS位置更新请求;
S120, 根据该 GPRS位置更新请求, 获取该用户签约的 PDP上下文的 下发控制条件;
S130, 根据该下发控制条件, 确定是否向该 SGSN发送该 PDP上下文; 控制 PDP上下文下发的装置在接收到 SGSN发送的用户的 GPRS位置 更新请求之后, 可以根据该 GPRS位置更新请求, 获取该用户签约的 PDP 上下文的下发控制条件,并根据该下发控制条件确定是否向该 SGSN发送该 PDP上下文。
因此, 本发明实施例的控制 PDP上下文下发的方法, 通过基于 PDP上 下文的下发控制条件, 控制 PDP上下文的下发, 能够避免产生不必要的业 务流量, 提升用户的业务感受, 并能减少运营商的客服工作量, 从而能够降 低运营商的运营成本。
应理解, 在本发明实施例中, 用户签约的 PDP上下文可以为用户签约 的全部 PDP上下文中的一个或一类 PDP上下文, 也可以为用户签约的部分 PDP上下文或全部 PDP上下文, 应根据具体情况而定, 本发明实施例并不 对此进行限定。
还应理解, 在本发明实施例中, 下发控制条件可以是基于具体用户的具 体 PDP上下文配置的, 例如, 可以为每一个用户的每一个 PDP上下文配置 一个下发控制条件, 例如, 为每一个用户的每一个 PDP上下文配置用于指 示下发网络范围的下发控制条件; 在本发明实施例中, 下发控制条件也可以 不^ ϋ于具体 PDP上下文配置的, 例如, 可以基于网络, 配置各个网络支 持的 PDP上下文; 因此, 在本发明实施例中, 只要是能够控制该 PDP上下 文的下发的条件, 都可以称之为该 PDP上下文的下发控制条件。
在本发明实施例中, 下发控制条件可以是人为配置的, 例如, 可以根据 用户对某 PDP上下文对应的 GPRS业务的网络需求和 /或各个网络为该 GPRS 业务提供的无线带宽, 人为配置用于指示该 PDP上下文的下发网络范围的 下发控制条件; 在本发明实施例中, 下发控制条件也可以是控制 PDP上下 文下发的装置自动设置的, 例如, 当在某网络下应用某 PDP上下文对应的 GPRS业务的用户达到饱和时, 可以自动设置下发控制条件, 用于指示暂停 向该网络下的 SGSN下发该 PDP上下文, 直到在该网络下应用该 PDP上下 文对应的 GPRS业务的用户低于饱和值, 取消该下发控制条件。
在本发明实施例中, 控制 PDP上下文下发的装置可以直接根据下发控 制条件确定是否向 SGSN发送该用户签约的 PDP上下文, 例如, 运营商需 要暂停或取消某 GPRS 业务, 可以人为配置用于指示在所有网络不下发该 GPRS业务对应的 PDP上下文的下发控制条件,在接收到签约该 GPRS业务 对应的 PDP上下文的用户的 GPRS位置更新请求之后, 控制 PDP上下文下 发的装置可以直接根据该下发控制条件确定不向 SGSN发送该 GPRS业务对 应的 PDP上下文; 控制 PDP上下文下发的装置也可以根据下发控制条件并 结合其他参数确定是否向 SGSN发送该用户签约的 PDP上下文, 例如, 在 下发控制条件指示该用户签约的 PDP上下文的下发网络范围或下发时间范 围时, 控制 PDP上下文下发的装置可以根据该下发控制条件并结合用户当 前接入的网络或用户当前接入的时间确定是否向 SGSN发送该 PDP上下文。
在本发明实施例中, 当在下发控制条件指示该 PDP上下文的下发网络 范围时, 如图 2所示, 方法 100还可以包括: S140, 根据该 GPRS位置更新请求中携带的 SGSN的标识(Identity, 筒 称 "ID" )确定该用户当前接入的网络;
其中, S130中确定是否向该 SGSN发送该 PDP上下文, 包括:
S135 ,根据该用户当前接入的网络和该下发控制条件指示的下发网络范 围, 确定是否向该 SGSN发送该 PDP上下文; 当该用户当前接入的网络属 于该下发网络范围时, 确定向该 SGSN发送该 PDP上下文; 当该用户当前 接入的网络不属于该下发网络范围时, 确定不向该 SGSN发送该 PDP上下 文。
应理解, 在本发明实施例中, 也可以根据该 GPRS位置更新请求中携带 的其他信息确定用户当前接入的网络, 本发明实施例并不对此进行限定。
在本发明实施例中, 下发网络范围可以是在给用户签约该 PDP上下文 时人为配置的,例如,根据用户的需求和 /或人为统计的网络带宽情况人为配 置该 PDP上下文的下发网络范围, 例如, 当用户只需要在国内应用该 PDP 上下文对应的 GPRS业务时, 则将该 PDP上下文的下发控制条件设置为在 国内下发, 再例如, 当用户需要在国内应用该 GPRS业务, 但是国内本网的 相关带宽资源不支持该 GPRS业务时, 则将该 PDP上下文的下发控制条件 设置为在国内他网下发。
在本发明实施例中, 用于指示下发网络范围的下发控制条件的控制选项 可以为不在任何网络下发、 只在国际他网下发、 只在国际本网下发、 只在国 际漫游时下发、 只在国内他网下发、 只在他网下发、 只在国内他网和国际本 网下发、 除了本国本网所有网络都下发、 只在本国本网下发、 只在本国本网 和国际他网下发、 只在本网下发、 除了国内他网都下发、 只在国内下发、 除 了国际本网都下发、 除了国际他网都下发、 所有网络都下发中的至少一种; 相应地, 用户当前接入的网络可以为国内本网、 国内他网、 国际本网或国际 他网。
应理解, 该下发网络范围不仅可以根据国内、 国际、 本网、 他网进行划 分, 也可以将国际和他网进行细分, 例如, ^ί 殳本网为移动, 则可以将他网 细分为电信和联通, 再例如, 假设国内为中国, 则可以将国际按国家细分, 分为美国、 日本、 英国等, 应根据具体情况而定, 本发明实施例并不对此进 行限定。
在本发明实施例中, 如图 3所示, 方法 100的 S120中, 获取该用户签 约的 PDP上下文的下发控制条件, 还可以包括:
S124, 根据该 GPRS位置更新请求中携带的 SGSN的 ID确定该用户当 前接入的网络;
S128, 根据该用户当前接入的网络, 获取下发控制条件, 该下发控制条 件用于指示该用户当前接入的网络支持的 PDP上下文;
其中, S130中确定是否向该 SGSN发送该 PDP上下文, 还可以包括: S138, 根据该用户当前接入的网络支持的 PDP上下文, 确定是否向该 SGSN发送该 PDP上下文。
其中, 当该 PDP上下文属于该用户当前接入的网络支持的 PDP上下文 时, 可以确定向该 SGSN发送该 PDP上下文; 当该 PDP上下文不属于该用 户当前接入的网络支持的 PDP上下文时,可以确定不向该 SGSN发送该 PDP 上下文。
在本发明实施例中, 确定用户当前接入的网络支持的 PDP上下文可以 为确定该用户当前接入的网络支持的 PDP上下文的类别, 名称等, 也可以 为别的信息, 本发明实施例并不对此进行限定。
应理解, 在本发明实施例中, 可以人为配置各个网络支持的 PDP上下 文, 例如, 基于各个 PDP上下文对应的 GPRS业务带宽需求和各个网络可 以为各个 PDP上下文对应的 GPRS业务提供的带宽, 人为配置各个网络支 持的 PDP上下文; 在本发明实施例中, 控制 PDP上下文下发的装置也可以 根据检测到的各个 PDP上下文对应的 GPRS业务带宽需求和各个网络为各 个 PDP上下文对应的 GPRS业务提供的带宽, 自动配置并随时更新各个网 络支持的 PDP上下文。
在本发明实施例中, 如果某 PDP上下文的下发控制条件包括两种或两 种以上的条件时, 可以设置下发规则, 例如, 可以设置为只有满足所有条件 时, 才下发该 PDP上下文, 或者只要满足一个条件就可以下发该 PDP上下 文, 或者为所有条件设置优先级, 只有满足优先级高的条件时, 才下发该 PDP上下文; 例如, 当下发控制条件指示该 PDP上下文的下发网络范围和 该用户当前接入的网络支持的 PDP上下文时, 可以依据设置的下发规则, 确定是否下发该 PDP上下文, 例如, 下发规则用于指示只有满足所有条件 才确定下发该 PDP上下文时, 则只有当该用户当前接入的网络属于该 PDP 上下文的下发网络范围且该 PDP上下文属于该用户当前接入的网络支持的 PDP上下文时, 才确定向该 SGSN发送该 PDP上下文; 或者, 下发规则用 于指示只要满足一个条件就可以下发该 PDP上下文时, 则只要该用户当前 接入的网络属于该 PDP上下文的下发网络范围或该 PDP上下文属于该用户 当前接入的网络支持的 PDP上下文时, 就可以确定向该 SGSN发送该 PDP 上下文, 或者为两者设置优先级, 并且只有满足优先级高的条件时, 才确定 下发该 PDP上下文, 例如, 用户当前接入的网络支持的 PDP上下文的优先 级较高时, 则只有该 PDP上下文属于用户当前接入的网络支持的 PDP上下 文时, 才确定下发该 PDP上下文。
应理解,在本发明实施例中,该下发控制条件还可以用于指示别的信息, 例如, 该用户签约的 PDP上下文对应的 GPRS业务的带宽需求, 控制 PDP 上下文下发的装置则可以根据用户当前接入的网络为该 PDP上下文对应的 GPRS业务提供的带宽是否满足该 GPRS业务的带宽需求, 而确定是否向该 SGSN发送该 PDP上下文。 其中, 可以人为配置 PDP上下文对应的 GPRS 业务的带宽需求信息和网络为 PDP上下文对应的 GPRS业务提供的带宽信 息,也可以根据检测到的网络状态自动设置并随时更新各个 GPRS业务的带 宽需求信息和各个网络为各个 GPRS业务提供的带宽信息。
在本发明实施例中, 当确定用户签约的全部 PDP上下文中需要下发的 PDP的上下文后, 可以向 SGSN发送确定的需要下发的 PDP上下文, 当确 定不向 SGSN发送该用户签约的任何 PDP上下文时, 则向该 SGSN发送 GPRS未签约的错误响应。
在本发明的实施例中, 控制 PDP上下文下发的装置可以为 HLR, 也可 以为别的装置, 为了便于理解, 下面将结合图 2并以 HLR为例详细描述根 据本发明实施例的控制 PDP上下文下发的方法。
在本发明的实施例中, PDP上下文对应的 GPRS业务可以为手机对讲机 业务( High Performance Push to Talk, 筒称 'ΉΡΡΤΤ" ), 也可以为无线应用 协议(Wireless Application Protocol, 筒称 "WAP" )业务, 也可以别的业务。 为了便于理解, 以下将以 HPPTT业务和 WAP业务为例进行说明。
图 4是根据本发明实施例的控制 PDP上下文下发的方法 200的示意性 流程图。 如图 4所示, 方法 200包括:
S201 , 当切换网络时, 用户向 SGSN发送注册请求。
S202, SGSN接收到用户发送的注册请求后, 向 HLR发送 GPRS位置 更新请求( GPRS_Update_location_Req )。
其中, 该 GPRS_Update_location_Req携带该用户信息和 SGSN的 ID。
5203 , 当接收到 SGSN发送的 GPRS_Update_location_Req后, HLR确 定用户当前接入的网络和各个 PDP上下文的下发控制条件。
具体的, HLR根据 SGSN的 ID确定用户当前接入的网络, 并根据用户 信息获取自身存储的该用户签约的各个 PDP上下文的下发控制条件, 例如, 根据 SGSN的 ID确定用户当前接入的网络为国内他网, HPPTT业务对应的 PDP上下文的下发网络范围为国内, WAP业务对应的 PDP上下文的下发网 络范围为本网, 且国内他网支持的 PDP上下文包括 HPPTT和 WAP对应的 PDP上下文。
5204, HLR根据用户当前接入的网络和用户签约的各个 PDP上下文的 下发控制条件, 分别确定各个 PDP上下文是否需要下发。
例如,对 HPPTT业务而言, HPPTT业务对应的 PDP上下文的下发网络 范围为国内, 用户当前接入的网络国内他网属于下发网络范围且该 PDP上 下文属于国内他网支持的 PDP上下文, 则可以确定向 SGSN发送该 PDP上 下文; 对于 WAP业务而言, WAP业务对应的 PDP上下文的下发网络范围 为本网,用户当前接入的网络国内他网不属于下发网络范围,确定不向 SGSN 下发 WAP业务对应的 PDP上下文。
当在 S204中 HLR确定有需要下发的 PDP上下文时,执行 S205、 S206、 和 S207; 当在 S205中 HLR确定不发送用户签约的任何 PDP上下文时, 则 执行 S208。
S205 , 当确定需要向 SGSN发送用户签约的 PDP上下文时, HLR根据 确定的需要下发的 PDP 上下文, 向 SGSN 发送插入用户数据请求 ( Insert_Subscriber_Date_Req ), 用于向 SGSN发送确定的需要下发的 PDP 上下文。 例如, 向 SGSN发送 HPPTT业务对应的 PDP上下文。
5206, HLR接收 SGSN根据 Insert_Subscriber_Date_Req发送的插入用 户数据响应 (Insert_Subsciber_Date_Rsp)。
5207, HLR更新该用户的位置信息, 并向 SGSN发送 GPRS位置更新 响应 ( GPRS_Update_location_Rsp )。
S208, 当确定不需要发送用户签约的任何 PDP上下文时, HLR向 SGSN 发送 GPRS未签约的错误响应。 应理解, 在本发明的各种实施例中, 上述各过程的序号的大小并不意味 着执行顺序的先后, 各过程的执行顺序应以其功能和内在逻辑确定, 而不应 对本发明实施例的实施过程构成任何限定。
