上行数据压缩的配置方法及设备
相关申请的交叉引用
本申请主张在2018年2月2日在中国提交的中国专利申请No.201810107370.3的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及移动通信技术领域,具体涉及一种上行数据压缩的配置方法及设备。
背景技术
上行数据压缩(UDC,Uplink Data Compression)技术是用户设备(UE,User Equipment)针对上行应用层数据或者信令进行压缩后发送,在基站侧对压缩后的数据进行解压,以节省空口传输的数据量,节约上行资源。
在上行数据压缩中,保持终端和基站能够正确的压缩/解压缩的解决方案可能有两种,一种是终端在发送上行数据的过程中建立压缩缓存中的数据内容,基站侧保留。之后以相应的规则进行解压。另外一种是终端和基站提前下载预定义或者保存一些用于解压的配置(profile)信息,可以通过一些信令交互确定启动哪个profile,一旦达成一致,终端和基站就可以保证正确压缩和解压。其中profile信息可以包括压缩方法,以及解压的buffer的信息或者解压的mapping映射表。
目前的LTE系统中,用于UDC的预置字典包括两种,一种是已经标准化的RFC 3485中定义的用于会话初始协议(SIP,Session Initiation Protocol)信令压缩的字典,另一种是运营商自行定义的字典(本文中简称为运营商定义字典)。用户设备通常只存储一个运营商定义字典。
在长期演进(LTE,Long Term Evolution)系统的UDC技术的标准化中,考虑支持运营商定义的字典。即用户设备使用运营商定义字典进行上行数据压缩,基站则使用该运营商定义字典进行数据解压。当用户设备存储了运营商定义字典时,可以上报用户设备存储有运营商定义字典的信息。并且用户 设备通常只需要支持一个运营商定义字典,即可以不存储多个运营商定义字典。
用户设备通常会发生地理位置上的移动。相关技术中的UDC的运营商定义字典的方案中,对于漫游场景,用户设备可以不上报支持了运营商定义字典。但这样就导致无法应用运营商定义字典进行上行数据压缩处理。对于切换的场景,如果用户设备当前的公共陆地移动网络(PLMN,Public Land Mobile Network)发生了更新,那么新的PLMN(目标PLMN)会从旧的PLMN(源PLMN)中获取了用户设备的设备能力信息,其中包含UDC的能力,而如果新旧PLMN的运营商定义字典不同,将因为新的PLMN使用了错误的运营商定义字典从而引起数据压缩/解压缩失败的问题,导致通讯出现故障。
发明内容

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。在下面的描述中,提供诸如具体的配置和组件的特定细节仅仅是为了帮助全面理解本公开的实施例。因此,本领域技术人员应该清楚,可以对这里描述的实施例进行各种改变和修改而不脱离本公开的范围和精神。另外,为了清楚和简洁,省略了对已知功能和构造的描述。
应理解,说明书通篇中提到的“一个实施例”或“一实施例”意味着与实施例有关的特定特征、结构或特性包括在本公开的至少一个实施例中。因 此,在整个说明书各处出现的“在一个实施例中”或“在一实施例中”未必一定指相同的实施例。此外,这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
在本公开的各种实施例中,应理解,下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,而不应对本公开实施例的实施过程构成任何限定。
本公开实施例中,网络侧设备通常是指基站。在本公开的实施例中,所述基站的形式不限,可以是宏基站(Macro Base Station)、微基站(Pico Base Station)、Node B(3G移动基站的称呼)、增强型基站(eNB)、家庭增强型基站(Femto eNB或Home eNode B或Home eNB或HeNB)、中继站、接入点、远端射频模块(Remote Radio Unit,RRU)、射频拉远头(Remote Radio Head,RRH)、5G移动通信系统中的网络侧节点,如gNB、中央单元(CU,Central Unit)和分布式单元(DU,Distributed Unit)等。所述用户设备可以是移动电话(或手机),或者其他能够发送或接收无线信号的设备,包括智能手机、个人数字助理(PDA)、无线调制解调器、无线通信装置、手持装置、膝上型计算机、无绳电话、无线本地回路(WLL)站、能够将移动信号转换为WiFi信号的客户终端(Customer Premise Equipment,CPE)或移动智能热点、智能家电、或其他不通过人的操作就能自发与移动通信网络通信的设备等。
如前文所述的,相关技术中的UDC的运营商定义字典的方案不适用于漫游场景和换PLMN的切换场景。例如,在用户设备漫游的时候,不管新接入的PLMN使用的运营商定义字典是不是跟该用户设备的运营商定义字典是否相同,用户设备都不能使用自己的运营商定义的字典,这可能会导致有些初始数据包的压缩率比较低,压缩效果比较差。而对于切换PLMN的切换场景,也可能存在新的PLMN下误使用了不同的运营商定义字典导致压缩和解压缩失败。
针对以上问题,本公开实施例给出了一种上行数据压缩的配置方法,来解决以上所述的部分或全部问题。请参照图1,本公开实施例提供了一种上行数据压缩的配置方法,该配置方法应用于用户设备侧,如图1所示,包括:
步骤101,用户设备在接收到目标基站发送的第一UDC配置信息时,根 据所述第一UDC配置信息,配置所述用户设备保存的运营商定义字典,用于上行数据的压缩处理;
其中,所述第一UDC配置信息包括使用所述用户设备保存的运营商定义字典的指示信息,所述目标基站所属的目标公共陆地移动网络PLMN不同于所述用户设备的源基站所属的源PLMN。
这里,目标基站是用户设备新接入的PLMN。用户设备在发生PLMN更新时,从旧PLMN(即源PLMN)接入了新PLMN(目标PLMN),具体地,用户设备可能是漫游到或者切换到目标PLMN。
由于源PLMN和目标PLMN的运营商定义字典可能并不相同,因此用户设备需要在接收到目标基站发送的所述第一UDC配置信息时,才去配置使用用户设备保存的运营商定义字典进行上行数据压缩处理。通过以上步骤,本公开实施例使得目标PLMN可以控制用户设备是否采用该用户设备保存的运营商定义字典,从而在目标PLMN的运营商定义字典和用户设备保存的运营商定义字典相同时,可以启用运营商定义字典进行上行数据压缩/解压缩,从而可以提高上行数据的压缩率,节省空口传输的数据量和上行资源。
在本公开实施例中,目标基站可以在确定用户设备保存的运营商定义字典能在目标PLMN使用时,向用户设备发送所述第一UDC配置信息。相反的,目标基站可以在确定所述用户设备的运营商定义字典不能在所述目标PLMN使用时,向用户设备发送第二UDC配置信息,所述第二UDC配置信息包括使用所述预定标准字典(如RFC 3485中定义的用于SIP信令压缩的字典)或内容为空的空字典(此时不使用字典进行压缩/解压缩)的指示信息。因此,本公开实施例的上述方法,还可以包括以下步骤:
步骤102,所述用户设备在接收到所述目标基站发送的第二UDC配置信息时,根据所述第二UDC配置信息,配置预定标准字典用于上行数据的压缩处理,或者配置取消上行数据的压缩处理。
通过以上步骤,本公开实施例可以在目标PLMN的运营商定义字典和用户设备保存的运营商定义字典不同时,控制用户设备和网络侧采用标准字典或不使用字典进行上行数据压缩/解压缩,从而可以减少或避免因运营商定义字典的不同所导致的通讯故障。
对于用户设备漫游到目标PLMN的场景,用户设备可以通过去附着/附着过程中的信令消息,接收目标基站发送的所述第一UDC配置信息或第二UDC配置信息。对于用户设备切换到目标PLMN的场景,用户设备可以通过无线资源控制(RRC)重配置新消息,接收目标基站发送的所述第一UDC配置信息或第二UDC配置信息。
为了确认用户设备保存的运营商定义字典是否可以在目标PLMN使用,本公开实施例可以通过运营商定义字典对应的可用PLMN列表来进行指示,这里,所述可用PLMN列表包括有可以使用所述运营商定义字典的PLMN的标识。在本公开实施例中,在接收上述第一、第二UDC配置信息之前,用户设备可以预先获取运营商定义字典及其对应的可用PLMN列表,并保存在用户设备的本地,具体的获取方式可以是:1)预先在用户设备中配置上述运营商定义字典及其对应的可用PLMN列表,例如在设备出厂设置中进行配置;2)由核心网下发,例如通过空中下载技术(OTA,Over-the-Air Technology)或者类似于接入网发现和选择功能(ANDSF,Access Network Discovery and Selection Function)下发给用户设备。
作为第一种实现方式,本公开实施例可以由用户设备来确定用户设备保存的运营商定义字典能否在目标PLMN使用。此时,所述用户设备在接入至所述目标PLMN时,可以根据本地保存的运营商定义字典及其对应的可用PLMN列表,确定所述目标PLMN是否存在于所述可用PLMN列表中:
1)在所述目标PLMN存在于所述可用PLMN列表时,用户设备可以向所述目标基站发送一表示所述用户设备支持运营商定义字典的第一指示信息;目标基站接收到该第一指示信息后,可以确定用户设备保存的运营商定义字典能在本目标PLMN使用,此时目标基站直接向用户设备发送所述第一UDC配置信息,以配置用户设备启用运营商定义字典;后续,用户设备和目标基站可以基于同一运营商定义字典进行上行数据压缩/解压缩。
2)在所述目标PLMN不存在于所述可用PLMN列表时,所述用户设备可以向所述目标基站发送一表示所述用户设备不支持运营商定义字典的第二指示信息;目标基站接收到该第二指示信息后,可以确定用户设备保存的运营商定义字典不能在本目标PLMN使用,此时目标基站直接向用户设备发送 所述第二UDC配置信息,以配置用户设备不启用运营商定义字典或使用标准字典。
作为第二种实现方式,本公开实施例可以由目标基站来确定用户设备保存的运营商定义字典能否在目标PLMN使用。此时,所述用户设备在获取所述运营商定义字典和可用PLMN列表并保存在本地之后,可以将所述可用PLMN列表发送至所述源PLMN,具体地,用户设备可以在向源PLMN上报用户设备的UDC能力时,上报所述可用PLMN列表。例如,通过UE-EUTRA-Capability消息,将所述可用PLMN列表发送至所述源PLMN。下面提供了一个具体示例,可以在UE-EUTRA-Capability消息中增加以下的信息以发送所述可用PLMN列表,其中,availablePLMN-List表示运营商定义字典(operator defined dictionary)可以在哪些PLMN下使用。
Figure PCTCN2019072792-appb-000001
源PLMN接收到用户设备上报的所述可用PLMN列表后,可以保存在源PLMN中,例如保存在移动性管理实体(MME)中。在终端接入到目标PLMN时,目标基站(即用户设备当前接入的目标PLMN下的基站)可以从所述用户设备的源PLMN处,获取所述可用PLMN列表,具体地,目标基站可以在获取用户设备的能力信息时,获取所述可用PLMN列表。然后,目标基站可以根据所述目标PLMN是否存在于所述可用PLMN列表中,确定所述用户设备的运营商定义字典是否能在目标PLMN使用。在用户设备的运营商定义字典能在目标PLMN使用时,目标基站发送所述第一UDC配置信息;在用户设备的运营商定义字典不能在目标PLMN使用时,目标基站发送所述第二 UDC配置信息。
更进一步地,考虑到运营商定义字典可能包括有版本号,本公开实施例所述用户设备在获取所述运营商定义字典时,还获取所述运营商定义字典的版本号;进而所述用户设备还将所述运营商定义字典的版本号发送至所述源PLMN。源PLMN接收到用户设备上报的所述可用PLMN列表及所述版本号后,可以保存在源PLMN中,例如保存在移动性管理实体(MME)中。此时,所述目标PLMN从所述用户设备的源PLMN处,获取所述可用PLMN列表以及所述用户设备保存的运营商定义字典的版本号。具体地,目标基站可以在获取用户设备的能力信息时,获取所述可用PLMN列表及所述版本号。在进行判断时,仅在所述目标PLMN存在于所述可用PLMN列表中,且所述目标PLMN保存的运营商定义字典的版本号,与所述用户设备保存的运营商定义字典的版本号相同时,确定所述用户设备保存的运营商定义字典能在目标PLMN使用,否则,确定所述用户设备保存的运营商定义字典不能在目标PLMN使用。
以上第二种实现方式中,目标基站需要从源PLMN处获取用户设备的运营商定义字典的可用PLMN列表。为了减少网络之间的交互数据量,本公开实施例提供了第三种实现方式。
在该第三实现方式中,基站可以维护PLMN和运营商定义字典之间的对应关系,所述对应关系中记录了PLMN可以使用的运营商定义字典。所述对应关系可以是预先配置在基站处,并可以通过网络间接口进行更新。这样,本公开实施例的用户设备在获取了运营商定义字典和可用PLMN列表并保存在本地之后,可以将所述用户设备的归属公共陆地移动网络(HPLMN)的标识发送至所述源PLMN。下面提供了一个具体示例,可以在UE-EUTRA-Capability消息或中增加以下的信息以发送所述HPLMN的标识(ID),其中,plmnIdentity-r15为HPLMN ID或者为与该运营商定义字典绑定的运营商的PLMN ID。
Figure PCTCN2019072792-appb-000002
Figure PCTCN2019072792-appb-000003
源PLMN接收到用户设备上报的所述HPLMN的标识后,可以保存在源PLMN中,例如保存在移动性管理实体(MME)中。后续,所述目标基站在需要确定用户设备保存的运营商定义字典能否在目标PLMN使用时,可以从所述用户设备的源PLMN处,获取所述用户设备的HPLMN的标识,进而根据目标基站本地维护的PLMN和运营商定义字典之间的对应关系,确定目标PLMN与归属HPLMN对应的运营商定义字典是否相同;以及,根据目标PLMN与归属HPLMN对应的运营商定义字典是否相同,确定所述用户设备的运营商定义字典是否能在目标PLMN使用。
更进一步地,考虑到字典版本号,在上述第三实现方式中,所述用户设备还可以将所述用户设备的HPLMN ID和所述运营商定义字典的版本号发送至所述源PLMN。下面提供了一个具体示例,可以在UE-EUTRA-Capability消息或中增加以下的信息以发送所述运营商定义字典的版本号,其中,supportedOperatorDic-r15表示所述版本号,(0..15)是版本号的取值范围;plmnIdentity-r15为HPLMN ID或者为与所述运营商定义字典绑定的运营商的PLMN ID。
Figure PCTCN2019072792-appb-000004
目标基站在确定用户设备保存的运营商定义字典能否在目标PLMN使用时,可以从所述用户设备的源PLMN处,获取所述用户设备的归属HPLMN的标识。然后,根据目标基站本地维护的PLMN和运营商定义字典及字典版本号之间的对应关系,确定目标PLMN与归属HPLMN对应的运营商定义字典以及字典版本号是否均相同,并根据目标PLMN与归属HPLMN对应的运营商定义字典以及字典版本号是否均相同,确定所述用户设备的运营商定义字典是否能在目标PLMN使用。具体的,只有在目标PLMN与归属HPLMN 对应的运营商定义字典相同,且字典版本号也相同时,才确定所述用户设备的运营商定义字典能在目标PLMN使用,否则,确定为不能使用。
以上主要从用户设备侧描述了本公开实施例的上行数据压缩的配置方法,并结合目标基站侧进行了相应介绍。下面请参照图2,给出了目标基站侧的方法流程,其中,目标基站为用户设备在目标PLMN下接入的基站。如图2所示,该方法包括:
步骤201,目标基站在确定用户设备保存的第一运营商定义字典能在目标公共陆地移动网络PLMN使用时,向用户设备发送第一UDC配置信息;
其中,目标PLMN为目标基站所属的PLMN,且不同于所述用户设备的源基站所属的源PLMN,所述第一UDC配置信息包括使用所述第一运营商定义字典的指示信息。
这里,在目标基站发送第一UDC配置信息后,可以针对所述用户设备后续发送的上行数据,利用所述第一运营商定义字典进行解压缩,从而可以提高上行数据的压缩率,节省空口传输的数据量和上行资源。
在目标基站确定所述第一运营商定义字典不能在所述目标PLMN使用时,本公开实施例的上述方法,还可以包括以下步骤:
步骤202,目标基站在确定所述第一运营商定义字典不能在所述目标PLMN使用时,向用户设备发送第二UDC配置信息,所述第二UDC配置信息包括使用所述预定标准字典或内容为空的空字典的指示信息。
通过以上步骤,本公开实施例可以减少或避免因目标基站和用户设备处的运营商定义字典的不同所导致的通讯故障。
对应于上文的第一种实现方式,在步骤201中,目标基站可以在接收到所述用户设备发送的一表示所述用户设备支持第一运营商定义字典的指示信息时,直接确定用户设备保存的第一运营商定义字典能在目标公共陆地移动网络PLMN使用;而在步骤202中,目标基站可以在接收到所述用户设备发送的一表示所述用户设备不支持第一运营商定义字典的指示信息时,直接确定用户设备保存的第一运营商定义字典不能在目标公共陆地移动网络PLMN使用。可以看出,以上步骤201和202中,目标基站不需要进行运营商定义字典可用性的判断,而是直接根据接收到的不同指示信息直接下发不同的配 置信息。
对应于上文的第二种实现方式,目标基站需要进行运营商定义字典可用性的判断。此时,目标基站可以在用户设备接入(如用户设备漫游或切换到目标基站)时,从所述用户设备的源PLMN处,获取可用PLMN列表,所述可用PLMN列表包括有可以使用所述第一运营商定义字典的PLMN的标识;然后,根据所述目标PLMN是否存在于所述可用PLMN列表中,确定所述第一运营商定义字典是否能在目标PLMN使用。图3给出了第二种实现方式中相关设备之间的信息交互。
考虑到字典版本号,所述目标基站可以在用户设备接入时,从所述用户设备的源PLMN处,获取可用PLMN列表以及所述用户设备保存的所述第一运营商定义字典的版本号;然后,仅在所述目标PLMN存在于所述可用PLMN列表中,且所述目标PLMN保存的所述第一运营商定义字典的版本号,与所述用户设备保存的所述第一运营商定义字典的版本号相同时,确定所述第一运营商定义字典能在目标PLMN使用,否则,确定为不能在目标PLMN使用。
对应于上文的第三种实现方式,目标基站也需要进行运营商定义字典可用性的判断。此时,所述目标基站可以从所述用户设备的源PLMN处,获取所述用户设备的HPLMN的标识。然后,目标基站根据本地维护的PLMN和运营商定义字典之间的对应关系,确定目标PLMN与归属HPLMN对应的运营商定义字典是否相同;进而,根据目标PLMN与归属HPLMN对应的运营商定义字典是否相同,确定所述第一运营商定义字典是否能在目标PLMN使用。
考虑到字典版本号,所述目标基站可以从所述用户设备的源PLMN处,获取所述用户设备的归属HPLMN的标识。然后,根据本地维护的PLMN和运营商定义字典及字典版本号之间的对应关系,确定目标PLMN与归属HPLMN对应的运营商定义字典以及字典版本号是否均相同;进而,根据目标PLMN与归属HPLMN对应的运营商定义字典以及字典版本号是否均相同,确定所述第一运营商定义字典是否能在目标PLMN使用。
本公开实施例中,目标基站在上述第二实现方式中,需要从源PLMN获取用户设备的可用PLMN列表,在上述第三实现方式中,需要从源PLMN获 取用户设备的HPLMN的标识。由于通信故障或其他原因,可能导致上述信息的获取发生失败,为此,本公开实施例的目标基站,还可以在未能获取到所述可用PLMN列表(对应于第二种实现方式),或者,未能获取到所述用户设备的归属HPLMN的标识时(对应于第三种实现方式),向所述用户设备发送终端能力查询消息。用户设备收到上述查询消息后,按照前文的第一种实现方式进行判断,并发送对应的指示信息。后续,所述目标基站在接收所述用户设备发送的一表示所述用户设备支持第一运营商定义字典的指示信息时,可以确定所述第一运营商定义字典能在目标PLMN使用,以及,在接收到所述用户设备发送的一表示所述用户设备不支持第一运营商定义字典的指示信息,可以确定所述第一运营商定义字典不能在目标PLMN使用。
基于以上方法,本公开实施例还提供了实施上述方法的设备。
