下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案 进行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施 例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员 在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保 护的范围。
下面结合附图对本发明实施例数据传输的方法、 装置、 系统进行详 细描述。
本发明实施例提供了一种数据传输的方法, 如图 1所示, 包括: 1 01、 第一基站接收第一设备发送的请求消息。
其中, 所述请求消息中携带有请求数据的标识信息和所述第一设备 的标识信息。 所述第一设备包括 UE ( Us e r Equ i pmen t , 用户设备) 或第 二基站。
具体的, 当 UE需要获取数据时, 将请求消息发送至 UE的第一基站, 此时, 第一基站可以接收 UE发送的请求消息, 此处, 第一设备为 UE。
第一基站中存储数据, 若存储的数据中有 UE需获取的请求数据, 但 第二基站并没有存储的此请求数据时,第二基站可以向第一基站发送请求 消息, 此时, 第二基站为第一基站的请求基站, 此处, 第一设备为第二基 站。
需要说明的是, 所述第一基站与所述第一设备在一个簇中。
需要说明的是, 只有在同一个簇中的第一设备可以访问所述第一基 站存储的数据。
需要说明的是, 在本发明实例中, 簇由至少一个存储数据的基站, 及其服务的 UE组成。
1 02、 所述第一基站在已存储的数据中根据所述请求数据的标识信息 进行检索。
具体的, 第一基站中存储了数据。 在接收到请求消息后, 由于请求 消息中携带有请求数据的标识信息,所以第一基站根据请求消息中的请求 数据的标识信息检索已存储的数据, 也就是说, 第一基站根据请求数据的 标识信息, 查看已存储的数据的标识信息是否与请求数据的标识信息相 同, 若相同, 则说明第一基站中存储有相应的数据, 若不相同, 则说明第 一基站中没有存储相应的数据。
其中, 第一基站存储数据的可以使用以下方法: 在第一基站接收到 一个请求消息后, 第一基站先确定接收到此请求消息的次数, 也就是说, 第一基站统计共接收到此请求; %息的次数。所述第一基站确定获取的接收 到此请求消息的次数是否大于第一门限值。所述第一基站在确定所述接收 到此请求消息的次数大于第一门限值时,获取簇内允许拷贝所述匹配数据 的最大拷贝数, 及簇内已经存储所述匹配数据的次数; 所述第一基站在簇 内已经存储所述匹配数据的次数小于簇内允许拷贝所述匹配数据的最大 拷贝数时,存储所述匹配数据,并更新簇内已经存储所述匹配数据的次数。 需要说明的是, 第一基站中存储的数据可以是存储了完整的数据内 容, 也可是存储了部分数据内容, 本发明对此不做限制。
示例性的, 假如 UE向第一基站请求消息, 且发送的请求消息为视频 请求消息, 此时视频请求消息中携带了请求视频的标识信息, 例如视频的 I D ( I dent i ty , 身份标识号码)。 第一基站在接收到视频请求消息后, 根 据视频请求消息中的请求视频的标识信息查找已存储的视频信息。
1 03、 所述第一基站在检索出匹配数据时, 根据所述第一设备的标识 信息发送所述匹配数据至所述第一设备。
其中, 所述匹配数据是指与所述请求数据的标识信息相匹配的数据。 具体的, 第一基站根据请求消息中的请求数据的标识信息检索已存 储的数据, 若检索出匹配数据, 则将此匹配数据发送至第一设备。 也就是 说, 在步骤 101 中, 若第一基站接收到 UE发送的请求消息, 则将匹配数 据发送至 UE。 若第一基站接收到第二基站发送的请求消息, 则将匹配数 据发送至第二基站。
本发明实施例提供了一种数据传输的方法, 第一基站在接收到第一 设备发送的请求消息后,根据请求消息中的请求数据的标识信息检索已存 储的数据, 若第一基站中有匹配数据, 则基站直接将此匹配数据发送至第 一设备。 这样, 在基站侧存储数据, 可以使得基站服务的不同用户设备在 请求相同的数据时, 基站可以将匹配数据发送至不同的用户设备, 而无需 向网络侧发送请求消息,无需使网络侧建立多条相同的链路发送相同的数 据信息至不同的用户设备,从而能够减小数据传输对核心网带宽资源的占 用, 并且从基站侧直接发送至用户设备, 减少了用户设备的等待时间, 从 而提高了用户的体验。
本发明实施例提供了一种数据传输的方法, 如图 2所示, 包括:
201、 用户设备向第一基站发送请求消息。
其中, 所述请求消息中携带有请求数据的标识信息和所述用户设备 的标识信息,以使得在所述第一基站根据所述请求数据的标识信息检索所 述第一基站已存储的数据, 若检索出所述第一基站存储有匹配数据, 则所 述第一基站直接将所述匹配数据发送至所述用户设备。 其中, 所述匹配数据是指与所述请求数据的标识信息相匹配的数据。 具体的, 用户设备向第一基站发送请求消息时, 将需获取的数据信 息的标识信息添加至请求消息中, 发送至第一基站。
2 02、 所述用户设备接收所述第一基站发送的所述请求消息的响应消 息, 并 居所述响应消息^相应的处理。
具体的, 所述第一基站发送的所述响应消息包含所述匹配数据, 此 时用户设备接收所述第一基站发送的匹配数据,则并根据所述匹配数据进 行相应的处理。
所述请求消息的响应消息包含存储有所述匹配数据的第三存储设备 的标识信息。 此时, 用户设备接收所述第一基站发送的存储有所述匹配数 据的所述第三存储设备的标识信息。所述用户设备根据所述第三存储设备 的标识信息, 从所述第三存储设备获取所述匹配数据。
本发明实施例提供了一种数据传输的方法, 用户设备向第一基站发 送请求消息, 以使得第一基站在接收到用户设备发送的请求消息后, 根据 请求消息中的请求数据的标识信息检索第一基站中已存储的数据,若第一 基站中存储有匹配数据, 则第一基站直接此匹配数据发送至用户设备。 这 样, 在基站侧存储数据信息, 可以使得基站服务的不同用户设备在请求相 同的数据时, 基站可以将匹配数据发送至不同的用户设备, 而无需向网络 侧发送请求消息,无需使网络侧建立多条相同的链路发送相同的数据信息 至不同的用户设备, 从而能够减小数据传输对核心网带宽资源的占用, 并 且从基站侧直接发送至用户设备, 减少了用户设备的等待时间, 从而提高 了用户的体验。

具体的, 作为簇头的第三基站接收到请求消息后, 根据请求消息中 的请求数据的标识信息查找存储的簇中各个设备存储的数据的标识信息。 查找出存储的数据的标识信息与请求消息中的请求数据的标识信息相匹 配的第一存储设备。 并将第一存储设备的标识信息发送至第一基站。
其中, 作为簇头的第三基站在接收到请求消息后, 可以先根据请求 消息中的请求数据的标识信息查找自己存储的数据, 若查找到匹配数据, 则直接将匹配数据发送至第一基站。 若没有查找到匹配数据, 则说明第三 基站中没有存储第一基站要求的数据,则继续查找存储的簇中各个设备存 储的数据的标识信息。并将根据所述请求消息中的请求数据的标识信息确 定出存储有匹配数据的第一存储设备,并将所述第一存储设备的标识信息 发送至所述第一基站。 此时, 第一存储设备不包括第三基站。
当然, 第三基站也可以在接收到请求消息后, 直接根据请求消息中 的请求数据的标识信息查找存储的簇中各个设备存储的数据的标识信息。 并将根据所述请求消息中的请求数据的标识信息确定出存储有匹配数据 的第一存储设备, 并将所述第一存储设备的标识信息发送至所述第一基 站。 此时, 第一存储设备可以为第三基站。
进一步的, 第三基站可以以列表的形式存储簇中各个设备存储的数 据的标识信息。
需要说明的是, 第三基站可以以其他形式存储簇中各个设备存储的 数据的标识信息, 例如映射表形式, 本发明对此不做限制。
更进一步的, 若作为簇头的第三基站确定出簇中只有一个存储有匹 配数据的第一存储设备, 则将第一存储设备的标识信息发送至第一基站。 若作为簇头的第三基站确定出簇中有至少两个存储有匹配数据的第一存 储设备,则第三基站可以在至少两个存储有匹配数据的第一存储设备中任 选一个, 将选中的第一存储设备的标识信息发送至第一基站。 第三基站可 以根据预设算法选择出最优的存储有匹配数据的第一存储设备,并将此第 一存储设备的标识信息发送值第一基站。
需要说明的是, 若第一基站不是簇头, 则第一基站所在的簇是由第 一基站、 他邻基站及其服务的 UE组成的, 此时, 第一存储设备可以为其 他相邻基站。
31 01 c , 所述第一基站接收所述第二存储设备发送的匹配数据; 并发 送所述匹配数据至第一设备。
具体的, 若第一基站接收的请求消息是 UE发送的, 则将第一基站将 获取的匹配数据发送至 UE, 若第一基站接收的请求消息是第二基站发送 的, 则将第一基站获取的匹配数据发送至第二基站, 如图 8所示。
31 1 b , 所述第一基站根据所述第一存储设备的标识信息向所述第一 存储设备发送所述请求消息,以便所述第一存储设备接收到所述请求消息 后,将存储的与所述请求消息中的所述请求数据的标识信息相匹配的所述 匹配数据发送至所述第一基站。 第一存储设备接收请求消息。
具体的, 第一基站在接收到第一存储设备的标识信息后, 根据第一 存储设备的标识信息向第一存储设备发送请求消息, 可参考步骤 3081 c, 在此不再赘述。
31 1 1 c ,第一设备接收第一基站发送的匹配数据, 并进行相应的处理。 具体的, 若第一设备为第二基站, 则第二基站可以将接收到的匹配 数据发送至其服务的请求此匹配数据的 UE, 并判断是否需要存储此匹配 数据, 若需要存储此匹配数据, 将第二基站存储此匹配数据, 具体的判断 是否需要存储此匹配数据可参考步骤 31 9- 322, 在此不再赘述。
若第一设备为 UE,则 UE可以根据接收到的匹配数据进行相应的处理, 并且 UE继续执行步骤 31 5- 31 6。
31 2 b , 所述第一存储设备根据所述请求消息中携带的请求数据的标 识信息检索已存储的数据,并将检索出的存储的与所述请求消息中的所述 请求数据的标识信息相匹配的所述匹配数据发送至所述第一基站。
具体的, 第一存储设备在已存储的数据中根据请求消息中携带的请 求数据的标识信息进行检索,与第一基站在已存储的数据中根据请求消息 中携带的请求数据的标识信息进行检索相同, 可参考步骤 1 02, 在此不再 赘述。
31 3b , 所述第一基站接收所述第一存储设备发送的匹配数据; 并发 送所述匹配数据至第一设备。
具体的, 第一基站接收的请求消息是第一设备发送的, 则将第一基 站将获取的匹配数据发送至第一设备, 可参考步骤 31 01 c。 当第一设备为 UE时, 可以参考图 8所示。
31 4b , 第一设备接收匹配数据, 并进行相应的处理。
具体的, 第一设备为 UE, UE接收所述第一基站发送的匹配数据, 并 根据所述匹配数据进行相应的处理。
31 5、 所述 UE确定接收的请求消息对应的匹配数据是否需要存储。 具体的, 所述 UE确定向所述第一基站发送的所述请求消息的次数。 并检测所述向所述第一基站发送的所述请求消息的次数是否大于第一门 限值。 所述 UE在确定所述向所述第一基站发送的所述请求消息的次数大 于第一门限值时, 从簇头中获取簇内允许拷贝所述匹配数据的最大拷贝 数, 及簇内已经存储所述匹配数据的次数。 若簇内已经存储所述匹配数据 的次数小于簇内允许拷贝所述匹配数据的最大拷贝数, 则所述 UE确定出 需要存储所述匹配数据。
进一步的, 由于簇头为所述第一基站, 则所述 UE在确定向所述第一 基站发送的所述请求消息的次数大于第一门限值时,从簇头中获取簇内允 许拷贝所述匹配数据的最大拷贝数,及簇内已经存储所述匹配数据的次数 包括:
所述 UE在所述向所述第一基站发送的所述请求消息的次数大于第一 门限值时,从所述第一基站中获取簇内允许拷贝所述匹配数据的最大拷贝 数, 及簇内已经存储所述匹配数据的次数。
具体的, UE接收到请求消息对应的匹配数据后, UE统计向第一基站 发送此请求消息的次数,并将统计的向第一基站发送此请求消息的次数与 第一门限值进行比对,若统计的向第一基站发送此请求消息的次数比第一 门限值大, 则说明 UE经常需要获取此匹配数据, 则 UE需要存储接收到的 请求消息对应的匹配数据。 此时, UE 从第一基站中获取簇内允许拷贝所 述匹配数据的最大拷贝数, 及簇内已经存储所述匹配数据的次数。 UE 比 较簇内允许拷贝所述匹配数据的最大拷贝数,及簇内已经存储所述匹配数 据的次数,若比较出簇内允许拷贝所述匹配数据的最大拷贝数大于簇内已 经存储所述匹配数据的次数, 则 UE确定可以存储请求消息对应的匹配数 据。若比较出簇内允许拷贝所述匹配数据的最大拷贝数不大于簇内已经存 储所述匹配数据的次数,则说明簇内存储的请求消息对应的匹配数据已达 到最大值, 此时, UE不能存储请求消息对应的匹配数据, 如图 9所示。
31 6、 若 UE 确定需要存储接收的请求消息对应的匹配数据, 则存储 接收的请求消息对应的匹配数据。
具体的, UE 在确定了需要存储请求消息对应的匹配数据时, 将请求 消息对应的匹配数据存储至 UE的空闲存储空间中。 UE存储匹配数据受, 并更新簇内已经存储所述匹配数据的次数。
进一步的, 所述 UE将更新的簇内已经存储所述匹配数据的次数发送 至簇头, 以使得簇头更新簇内已经存储所述匹配数据的次数。
具体的, 由于第一基站是簇头, 所以 UE可以将更新的簇内已经存储 所述匹配数据的次数发送至第一基站,以使得所述第一基站更新簇内已经 存储所述匹配数据的次数。
31 7、 第一基站确定 UE 发送的请求消息对应的匹配信息是否需要存 储。
具体的, 所述第一基站确定接收到所述请求消息的次数。 在确定所 述接收到所述请求消息的次数大于第一门限值时,获取簇内允许拷贝所述 匹配数据的最大拷贝数, 及簇内已经存储所述匹配数据的次数。 第一基站 在簇内已经存储所述匹配数据的次数小于簇内允许拷贝所述匹配数据的 最大拷贝数时, 存储所述匹配数据。 即为, 在簇内已经存储所述匹配数据 的次数小于簇内允许拷贝所述匹配数据的最大拷贝数时,第一基站确定要 存储匹配数据。
其中, 第一基站需要统计接收到此请求消息的次数, 并将统计的接 收的到的请求消息的次数与第一门限值进行比对,若统计的接收的到的请 求消息的次数比第一门限值大, 则说明第一基站服务的 UE经常需要获取 此匹配数据, 则第一基站需要存储此请求消息对应的匹配数据。 此时, 第 一基站获取簇内允许拷贝所述匹配数据的最大拷贝数,及簇内已经存储所 述匹配数据的次数。第一基站比较簇内允许拷贝所述匹配数据的最大拷贝 数, 及簇内已经存储所述匹配数据的次数, 若比较出簇内允许拷贝所述匹 配数据的最大拷贝数大于簇内已经存储所述匹配数据的次数,则第一基站 确定可以存储请求消息对应的匹配数据。若比较出簇内允许拷贝所述匹配 数据的最大拷贝数不大于簇内已经存储所述匹配数据的次数,则说明簇内 存储的请求消息对应的匹配数据已达到最大值, 此时, 第一基站不能存储 请求消息对应的匹配数据, 如图 1 0所示。
可选的, 若第一基站不是所在簇的簇头, 则第一基站可以通过簇头 获取簇内允许拷贝所述匹配数据的最大拷贝数,及簇内已经存储所述匹配 数据的次数。 若第一基站是所在簇的簇头, 则第一基站直接获取自身存储 的簇内允许拷贝所述匹配数据的最大拷贝数,及簇内已经存储所述匹配数 据的次数。
进一步的, 在第一基站确定接收的到的请求消息的次数不大于第一 门限值时, 说明第一基站服务的 UE不经常需要获取此匹配数据, 第一基 站无需存储此请求消息对应的匹配数据。
示例性的,假设 U E向第一基站发送的请求消息为一个视频请求消 , 。 此第一基站此时需要统计接收到此视频请求消息的次数为 7, 第一门限值 为 5, 则第一基站将统计的接收到的此视频请求消息的次数 7与第一门限 值 5进行比对,发现统计的接收到的此视频请求消息的次数大于第一门限 值 5, 说明第一基站服务的 UE经常请求此视频信息, 则此时, 若第一基 站是簇头,则第一基站直接获取自身存储的簇内允许拷贝所述匹配数据的 最大拷贝数为 8, 簇内已经存储所述匹配数据的次数 4。 若第一基站不是 簇头,则第一基站通过簇头获取簇内允许拷贝所述匹配数据的最大拷贝数 为 8, 簇内已经存储所述匹配数据的次数 4, 检测出簇内已经存储所述匹 配数据的次数 4小于簇内允许拷贝所述匹配数据的最大拷贝数为 8, 所以 第一基站确定可以存储此视频请求消息对应的匹配视频信息。
需要说明的是, 第一门限值是预设设置的。
31 8、 若第一基站确定需要存储请求消息对应的匹配数据, 则存储请 求消息对应的匹配数据。
具体的, 第一基站在确定了需要存储请求消息对应的匹配数据时, 将获取的请求消息对应的匹配数据存储至第一基站的空闲存储空间中。并 且所述第一基站更新簇内已经存储所述匹配数据的次数。
其中, 若所述第一基站是所在簇的簇头, 则第一基站直接更新自身 存储的簇内已经存储所述匹配数据的次数。
若所述第一基站不是所在簇的簇头, 则所述第一基站可以将更新的 簇内已经存储所述匹配数据的次数发送至所述簇头,以使得所述簇头更新 簇内已经存储所述匹配数据的次数。
如上例所述, 若第一基站是所在簇的簇头, 则第一基站直接将自身 存储的簇内已经存储所述匹配数据的次数由 4更新为 5。
若第一基站不是所在簇的簇头, 则第一基站在将匹配视频信息存储 至空闲的存储空间时,可以将簇内已经存储所述匹配数据的次数更新为 5, 将簇内已经存储所述匹配数据的次数 5发送至簇头,以使得簇头将簇内已 经存储所述匹配数据的次数由 4更新为 5。
进一步的, 所述第一基站存储所述匹配数据包括: 所述第一基站确 定空闲存储空间的大小是否大于所述匹配数据的大小。若所述空闲存储空 间的大小大于所述匹配数据的大小,则所述第一基站直接存储所述匹配数 据。 若所述空闲存储空间的大小不大于所述匹配数据的大小, 则所述第一 基站根据 LRU ( Lea s t Re cen t l y U s ed , 最近最少使用算法) 算法更新所 述空闲存储空间,以使得所述空闲存储空间的大小大于所述匹配数据的大 小, 并将所述匹配数据存储至更新后的所述空闲存储空间。 需要说明的是, 本发明实施例也可使用其他算法更新空闲存储空间, 例如先进先出算法, 本发明对此不做限制。
需要说明的是, 在第一基站不是簇头的情况下, 第一基站还可以将 请求消息直接发送至所在簇的簇头,以获取与所述请求消息相对应的匹配 数据。 具体的可参考第二基站向第一基站发送请求消息的过程, 在此不再 赘述。
31 9、 在所述第一基站为簇头的情况下, 所述第一基站监测簇中已存 储的所述匹配数据的服务状态。
其中, 所述服务状态包括: 服务成功状态及服务失败状态。 所述服 务成功状态是指将所述匹配数据发送至第一设备。所述服务失败状态是指 没有将所述匹配数据发送至第一设备。
具体的, 为了实现若数据在一个簇内的请求量变得非常大时, 簇内 设置的簇内允许拷贝所述匹配数据的最大拷贝数也随之进行相应的调整, 第一基站作为所在簇的簇头需要监测所述簇中已存储的匹配数据的服务 状态。
示例性的, 如数据信息为视频信息, 则为了实现随着簇内一个视频 信息的访问量变的非常大时, 例如此视频有 1百万访问量, 则此时簇内设 置的簇内允许拷贝所述视频信息的最大拷贝数也需随之进行相应的调整。 第一基站需要监测此视频信息的服务状态。
32 0、 所述第一基站根据所述匹配数据的所示服务状态统计所述匹配 数据的服务失败状态的个数, 及簇中接收到的全部所述请求 %息的个数。
需要说明的是, 匹配数据的服务失败状态可以是由于网络时延过长, 传输过程中拥堵等原因造成。 当一个数据信息被大量 UE获取时, 会造成 匹配数据呈服务失败状态, 所以, 在实现若数据信息在一个簇内的请求量 变得非常大,簇内设置的簇内允许拷贝所述匹配数据的最大拷贝数也随之 进行相应的调整时, 第一基站需统计匹配数据呈服务失败状态的个数。
需要说明的是, 统计簇中接收到的全部所述请求消息的个数是指统 计簇中接收到的所有请求消息,包括第一设备发送的请求消息也包括第一 基站接收的其他设备发送的请求 % , 。
32 1、 所述第一基站比较统计的所述匹配数据的服务失败状态的个数 及所述簇中接收到的全部所述请求消息的个数。
具体的, 第一基站统计出匹配数据的服务失败状态的个数, 及统计 出簇内接收到的全部请求消息的个数,比较统计出的匹配数据的服务失败 状态的个数, 及统计出的簇内接收到的全部请求消息的个数。 可以获取统 计出的匹配数据的服务失败状态的个数占统计出的簇内接收到的全部请 求消息的个数的百分比。
需要说明的是, 也可获取统计出的匹配数据的服务失败状态的个数 与统计出的簇内接收到的全部请求消息的个数间的差值,还可是其他的比 较方法, 本发明对此不做限制。
322、 所述第一基站根据比较结果, 更新所述允许拷贝所述匹配数据 的最大拷贝数。
具体的, 若所述比较结果大于第二门限值, 则所述第一基站增加所 述允许拷贝匹配数据的最大拷贝数。 若所述比较结果小于第三门限值, 则 所述第一基站减小允许拷贝所述匹配数据的最大拷贝数。
需要说明的是, 第二门限值及第三门限值是预先设置的。
示例性的, 假设第一基站在步骤 31 9 中计算出了统计出的匹配数据 的服务失败状态的个数占统计出的簇内接收到的全部请求消息的个数的 百分比。 若第二门限值为 1 0%, 第三门限值为 5%。 若计算出统计出的匹配 数据的服务失败状态的个数占统计出的簇内接收到的全部请求消息的个 数的百分比为 1 5%, 大于第二门限值, 则所述第一基站需要增加允许拷贝 所述匹配数据的最大拷贝数。
本发明实施例提供了一种数据传输的方法, 第一基站在接收到第一 设备发送的请求消息后,根据请求消息中的请求数据的标识信息检索已存 储的数据, 若第一基站中有匹配数据, 则基站直接将此匹配数据发送至第 一设备。 这样, 在基站侧存储数据, 可以使得基站服务的不同用户设备在 请求相同的数据时, 基站可以将匹配数据发送至不同的用户设备, 而无需 向网络侧发送请求消息,无需使网络侧建立多条相同的链路发送相同的数 据信息至不同的用户设备,从而能够减小数据传输对核心网带宽资源的占 用, 并且从基站侧直接发送至 UE, 减少了用户设备的等待时间, 从而提 高了用户的体验。根据用户设备对数据的需要动态的改变对数据信息在基 站侧的存储情况下, 进一步提高了系统存贮空间的有效性。
