本发明涉及无线接入技术领域，尤其涉及用户设备无线接入能力更新的方法、系统及装置。The present invention relates to the field of wireless access technology, in particular to a method, system and device for updating wireless access capabilities of user equipment.
背景技术Background technique
目前3GPP标准中对用户设备无线接入能力(UE radio access capabilities)做了明确的规定，用户设备无线接入能力是采用一套参数集来定义的。对于每一个无线接入能力参数，协议规定了它的取值范围；同时，为了满足不同的用户设备的实现，协议规定了一些不同的无线接入能力参数组合，每个用户设备会取其中的一套无线接入能力参数集来定义自己的无线接入能力。用户设备无线接入能力(UE radio access capabilities)的参数主要有以下几项：Currently, the 3GPP standard clearly defines UE radio access capabilities (UE radio access capabilities), which are defined by a set of parameter sets. For each wireless access capability parameter, the protocol specifies its value range; at the same time, in order to meet the realization of different user equipment, the protocol specifies some different combinations of wireless access capability parameters, and each user equipment will take one of them A set of wireless access capability parameter sets is used to define its own wireless access capability. The parameters of UE radio access capabilities mainly include the following items:
接入层版本指示(Access stratum release indicator)，下行是否具有与HS-DSCH配置并存的能力(DL capability with simultaneous HS-DSCHconfiguration)，PDCP能力，RLC能力，传输信道能力(Transport channelcapability)，RF能力FDD，RF能力TDD，RF能力TDD 1.28Mcps(RF capabilityTDD 1.28Mcps)，物理信道能力(Physical channel capability)，用户设备多模式多无线系统能力(UE multi-mode/multi-RAT capability)，安全能力(Securitycapability)，用户设备定位能力(UE positioning capability)，测量能力(Measurement capability)，分集类型(Device type)和是否支持系统消息类型11bis(Support for System Information Block type 11bis)。Access stratum release indicator, whether the downlink has the ability to coexist with HS-DSCH configuration (DL capability with simultaneous HS-DSCH configuration), PDCP capability, RLC capability, transport channel capability (Transport channel capability), RF capability FDD , RF capability TDD, RF capability TDD 1.28Mcps (RF capabilityTDD 1.28Mcps), physical channel capability (Physical channel capability), user equipment multi-mode multi-radio system capability (UE multi-mode/multi-RAT capability), security capability (Securitycapability ), user equipment positioning capability (UE positioning capability), measurement capability (Measurement capability), diversity type (Device type) and whether to support system information type 11bis (Support for System Information Block type 11bis).
网络侧在为用户设备分配需要的资源时，不能超逾了该用户设备的无线接入能力。When the network side allocates required resources to the user equipment, it cannot exceed the wireless access capability of the user equipment.
现有的用户设备无线接入能力更新功能主要用于处于连接态的用户设备发起无线接入能力的改变。用户设备在处于连接态时，某些无线接入能力参数可以发生变化，见下表1。The existing user equipment wireless access capability updating function is mainly used for the user equipment in the connected state to initiate a change of the wireless access capability. When the user equipment is in the connected state, some wireless access capability parameters may change, as shown in Table 1 below.
表1Table 1
用户设备在连接态时，可能在某些场景下希望改变无线接入能力参数，比如：初始时用户设备同时接收普通业务和MBMS业务，MBMS业务接收结束后，用户设备希望提高最大下行速率(maximum permitted downlink data rate)、或者希望提高它的HSDPA等级(HSDPA category)，此时就可以触发用户设备无线接入能力更新过程。具体过程参见图1，图1为现有技术中用户设备无线接入能力更新实现流程图。用户设备首先发起一个用户设备能力信息(UE CapabilityInformation)消息来通知UTRAN中的RNC，该消息中包含用户设备所请求的无线接入能力参数。如果RNC支持用户设备无线接入能力参数的修改的话，会根据UE需要改变的参数来做对应修改，并通过用户设备能力信息确认(UE CapabilityInformation Confirm)消息来通知用户设备；对于某些参数的改变，还需要发起无线承载重配(Radio Bearer Reconfiguration)过程，由RNC向UE发送无线承载重配(Radio Bearer Reconfiguration)消息，携带重新配置的无线承载参数；当无线承载重配完成之后，UE向RNC返回无线承载重配完成(Radio BearerReconfiguration Complete)消息。相反，如果RNC不支持用户设备无线接入能力参数的修改，就会直接拒绝用户设备的请求。由于网络的无线资源是实时变化的，尤其是在热点地区，网络不支持用户设备无线接入能力更新的情况时有发生，在不支持时仅仅简单地拒绝用户设备的请求的方式不能够满足用户的需求，并且会降低用户的使用体验。When the user equipment is in the connected state, it may wish to change the radio access capability parameters in some scenarios. For example, the user equipment initially receives ordinary services and MBMS services at the same time. After receiving the MBMS services, the user equipment wishes to increase the maximum downlink rate (maximum permitted downlink data rate), or wish to improve its HSDPA level (HSDPA category), at this time, the process of updating the wireless access capability of the user equipment can be triggered. Refer to FIG. 1 for the specific process. FIG. 1 is a flow chart of updating the wireless access capability of the user equipment in the prior art. The user equipment first initiates a user equipment capability information (UE CapabilityInformation) message to notify the RNC in the UTRAN, and the message includes the radio access capability parameter requested by the user equipment. If the RNC supports the modification of the wireless access capability parameters of the user equipment, it will make corresponding modifications according to the parameters that the UE needs to change, and notify the user equipment through the UE Capability Information Confirm (UE CapabilityInformation Confirm) message; for some parameter changes , it is also necessary to initiate the Radio Bearer Reconfiguration (Radio Bearer Reconfiguration) process, and the RNC sends a Radio Bearer Reconfiguration (Radio Bearer Reconfiguration) message to the UE, carrying the reconfigured Radio Bearer parameters; Return a Radio BearerReconfiguration Complete message. On the contrary, if the RNC does not support the modification of the radio access capability parameter of the user equipment, it will directly reject the request of the user equipment. Since the wireless resources of the network change in real time, especially in hotspot areas, it happens from time to time that the network does not support the update of the wireless access capability of the user equipment, and the method of simply rejecting the request of the user equipment cannot satisfy the user. requirements, and will degrade the user experience.

具体实施方式Detailed ways
本发明实施例提出一种用户设备无线接入能力更新的方法，参见图2，图2为本发明实施例用户设备无线接入能力更新的方法流程图。包括：An embodiment of the present invention proposes a method for updating a wireless access capability of a user equipment, see FIG. 2 , which is a flowchart of a method for updating a wireless access capability of a user equipment according to an embodiment of the present invention. include:
步骤210：接收用户设备发送的请求更新的无线接入能力参数；Step 210: Receive the radio access capability parameter requesting update sent by the user equipment;
步骤220：RNC判断用户设备所在区域是否能够满足用户设备所请求的无线接入能力，如果不能，则根据网络能力及资源状态修改所述请求更新的无线接入能力参数；Step 220: The RNC judges whether the area where the user equipment is located can meet the wireless access capability requested by the user equipment, and if not, modifies the requested wireless access capability parameter according to the network capability and resource status;
步骤230：RNC将修改后的无线接入能力参数发送至用户设备。Step 230: RNC sends the modified radio access capability parameter to the user equipment.
步骤230中，RNC将修改后的无线接入能力参数发送至用户设备的具体方式可以为：将修改后的无线接入能力参数包含在“用户设备无线接入能力(UERadio Access Capability)”消息元素(IE，Information Element)中，利用现有技术中已有的用户设备能力消息确认(UE Capability Information Confirm)消息，将所述“用户设备无线接入能力”IE承载在用户设备能力信息确认消息中，发送至用户设备。详见表2，表2为本发明实施例携带修改后的无线接入能力参数的用户设备能力消息确认消息的各项IE说明。In step 230, the specific manner in which the RNC sends the modified radio access capability parameter to the user equipment may be: include the modified radio access capability parameter in the "UERadio Access Capability (UERadio Access Capability)" message element (IE, Information Element), using the existing UE Capability Information Confirm (UE Capability Information Confirm) message in the prior art, the "User Equipment Wireless Access Capability" IE is carried in the UE Capability Information Confirm message , sent to the user device. See Table 2 for details. Table 2 is the description of each IE of the user equipment capability confirmation message carrying the modified wireless access capability parameter according to the embodiment of the present invention.
对于有些无线接入能力参数的更新，RNC还需要发起无线承载重配过程，即在步骤220和步骤230之间，可以进一步包括：RNC根据修改后的无线接入能力参数，发起无线承载重配过程。For the update of some radio access capability parameters, the RNC also needs to initiate a radio bearer reconfiguration process, that is, between steps 220 and 230, it may further include: RNC initiates radio bearer reconfiguration according to the modified radio access capability parameters process.
具体可以为：Specifically, it can be:
步骤221：RNC向用户设备发送无线承载重配(Radio BearerReconfiguration)消息，该消息中携带重新配置的无线承载参数。Step 221: RNC sends a radio bearer reconfiguration (Radio BearerReconfiguration) message to the user equipment, and the message carries reconfigured radio bearer parameters.
步骤222：用户设备向RNC返回无线承载重配完成(Radio BearerReconfiguration Complete)消息。Step 222: The user equipment returns a radio bearer reconfiguration complete (Radio BearerReconfiguration Complete) message to the RNC.

当用户设备当前所在区域无法满足其无线接入能力请求(如提高最大速率或支持HSDPA、HSUPA等)时，RNC可以选择能够满足用户设备所请求的无线接入能力的区域，将用户设备转移至该区域，具体可以通过现有技术中硬切换、软切换、重定向或小区更新等方式实现转移。用户设备的转移本身就是一种无线承载重配过程。When the current area where the user equipment is located cannot meet its wireless access capability request (such as increasing the maximum rate or supporting HSDPA, HSUPA, etc.), the RNC can select an area that can meet the wireless access capability requested by the user equipment, and transfer the user equipment to Specifically, this area can be transferred through methods such as hard handover, soft handover, redirection, or cell update in the prior art. The transfer of the user equipment itself is a radio bearer reconfiguration process.
以下举具体的实施例，详细介绍本发明用户设备无线接入能力更新的应用场景及实现方法。Specific embodiments are given below to introduce in detail the application scenario and implementation method of updating the wireless access capability of the user equipment according to the present invention.
实施例一：Embodiment one:
在本实施例中，初始状态下用户设备正在接收一个MBMS业务，并同时进行一个64kbps的普通业务。当MBMS业务终止时，用户设备向网络侧发送请求，请求将自己的普通业务能力提高至256kbps。此时网络侧的容量较低、或者由于接入的用户过多、负荷较重，无法满足用户256kbps的请求。RNC根据网络目前的资源状况，判断出可以将无线接入能力中的速率项提高至128kbps，即将该修改后的无线接入能力参数(128kbps的速率)发送至用户设备，然后发起无线承载重配过程，无线承载重配过程结束后，RNC通过用户设备能力信息确认(UE Capability Information Confirm)消息将修改后的无线接入能力参数通知用户设备。In this embodiment, in the initial state, the user equipment is receiving an MBMS service and simultaneously performing a 64kbps common service. When the MBMS service is terminated, the user equipment sends a request to the network side, requesting to increase its normal service capability to 256kbps. At this time, the capacity of the network side is low, or the user's request of 256 kbps cannot be satisfied due to too many connected users and a heavy load. According to the current resource status of the network, the RNC judges that the rate item in the wireless access capability can be increased to 128kbps, that is, it sends the modified wireless access capability parameter (128kbps rate) to the user equipment, and then initiates wireless bearer reconfiguration process, after the radio bearer reconfiguration process ends, the RNC notifies the user equipment of the modified radio access capability parameters through a UE Capability Information Confirm (UE Capability Information Confirm) message.
具体过程参见图3，图3为本发明实施例一用户设备无线接入能力更新的实现流程图。Refer to FIG. 3 for a specific process. FIG. 3 is a flow chart of implementing wireless access capability update of a user equipment according to Embodiment 1 of the present invention.
步骤301：用户设备原先的普通业务速率为64kbps，向RNC发送用户设备能力信息(UE Capability Information)消息，所请求的速率项为256kbps。Step 301: The original normal service rate of the user equipment is 64kbps, and the user equipment capability information (UE Capability Information) message is sent to the RNC, and the requested rate item is 256kbps.
步骤302：RNC判断出此时能够为用户提供128kbps的速率。Step 302: The RNC judges that the rate of 128 kbps can be provided for the user at this time.
步骤303～步骤304：RNC向用户设备发送无线承载重配(Radio BearerReconfiguration)消息，携带为提供128kbps的速率而重新配置的无线承载参数；重配完成后，UE向RNC返回无线承载重配完成(Radio Bearer ReconfigurationComplete)消息。Steps 303 to 304: RNC sends a radio bearer reconfiguration (Radio BearerReconfiguration) message to the user equipment, carrying the radio bearer parameters reconfigured to provide a rate of 128kbps; after the reconfiguration is completed, the UE returns to the RNC that the radio bearer reconfiguration is completed ( Radio Bearer ReconfigurationComplete) message.
步骤305：RNC向用户设备发送用户设备能力信息确认(UE CapabilityInformation Confirm)消息。Step 305: RNC sends a user equipment capability information confirmation (UE CapabilityInformation Confirm) message to the user equipment.
可见，在本实施例中，当网络暂时不能支持用户设备请求的256kbps的速率时，并不是直接拒绝用户设备的请求，而是根据网络的资源情况为用户设备提供128kbps的速率，通过这种方式最大限度地满足用户的需求。It can be seen that in this embodiment, when the network temporarily cannot support the rate of 256 kbps requested by the user equipment, it does not directly reject the request of the user equipment, but provides the user equipment with a rate of 128 kbps according to the resource conditions of the network. In this way To meet the needs of users to the greatest extent.
实施例二：Embodiment two:
在本实施例中，初始状态下用户设备正在接收一个MBMS业务，并同时进行一个普通业务。当MBMS业务终止时，用户设备向网络侧发送请求，请求将自己的普通业务更新为等级为12的HSDPA业务。此时网络侧的资源缺乏，无法满足用户设备的HSDPA业务等级为12的需求。RNC根据网络目前的资源状况，判断出可以为用户设备提供等级为10的HSDPA业务，即通过用户设备能力消息确认(UE Capability Information Confirm)消息通知用户设备修改后的无线接入能力参数。这种情况不需要进行无线承载重配过程。In this embodiment, in an initial state, the user equipment is receiving an MBMS service and simultaneously performing a common service. When the MBMS service is terminated, the user equipment sends a request to the network side, requesting to update its ordinary service to the HSDPA service of class 12. At this time, resources on the network side are insufficient, and cannot meet the requirement of the HSDPA service class 12 of the user equipment. According to the current resource status of the network, the RNC judges that the HSDPA service of level 10 can be provided for the UE, that is, the UE Capability Information Confirm (UE Capability Information Confirm) message is used to notify the UE of the modified radio access capability parameters. In this case, no radio bearer reconfiguration process is required.
具体过程参见图4，图4为本发明实施例二用户设备无线接入能力更新的实现流程图。Refer to FIG. 4 for a specific process. FIG. 4 is a flow chart of implementing wireless access capability update of user equipment according to Embodiment 2 of the present invention.
步骤401：用户设备原先使用普通业务，向RNC发送用户设备能力信息(UECapability Information)消息，请求提供等级为12的HSDPA业务。Step 401: The user equipment originally uses common services, and sends a user equipment capability information (UECapability Information) message to the RNC, requesting to provide HSDPA services with class 12.
步骤402：由于网络资源受限，RNC判断出此时能够为用户提供等级为10的HSDPA业务。Step 402: Due to limited network resources, the RNC judges that the HSDPA service of class 10 can be provided to the user at this time.
步骤403：RNC向用户设备发送用户设备能力信息确认(UE CapabilityInformation Confirm)消息，将HSDPA业务等级为10的参数包含在“用户设备无线接入能力(UE Radio Access Capability)”IE中，并将该IE携带与该消息中。Step 403: RNC sends user equipment capability information confirmation (UE CapabilityInformation Confirm) message to user equipment, and the parameter that HSDPA service level is 10 is included in " user equipment radio access capability (UE Radio Access Capability) " IE, and this IE is carried in this message.
实施例三：Embodiment three:

具体过程参见图5，图5为本发明实施例三用户设备无线接入能力更新的实现流程图。Refer to FIG. 5 for a specific process. FIG. 5 is a flow chart of implementing wireless access capability update of user equipment according to Embodiment 3 of the present invention.
步骤501：用户设备向RNC发送用户设备能力信息(UE CapabilityInformation)消息，请求新的无线接入能力。Step 501: The user equipment sends a UE Capability Information (UE CapabilityInformation) message to the RNC to request a new radio access capability.
步骤502：RNC判断出用户设备当前所在区域无法满足用户设备的请求，选择能够满足用户设备所请求的无线接入能力的区域。Step 502: The RNC determines that the current area where the user equipment is located cannot meet the request of the user equipment, and selects an area that can meet the wireless access capability requested by the user equipment.
步骤503：RNC向用户设备发送切换命令(Handover Command)，要求用户设备转移至步骤502所选出的区域。Step 503: RNC sends a handover command (Handover Command) to the user equipment, requiring the user equipment to transfer to the area selected in step 502.
步骤504：用户设备根据收到的切换命令(Handover Command)进行转移，并向RNC返回切换完成(Handover Complete)消息。Step 504: The user equipment performs handover according to the received handover command (Handover Command), and returns a handover complete (Handover Complete) message to the RNC.
步骤505：RNC向用户设备发送用户设备能力信息确认(UE CapabilityInformation Confirm)消息。Step 505: RNC sends a user equipment capability information confirmation (UE CapabilityInformation Confirm) message to the user equipment.
在本实施例中，通过将用户设备转移至其他区域，满足了用户设备的无线接入能力更新请求。步骤503和步骤504是实现转移的一种具体实现方式，本发明实施例还可以包括其他转移方式，如硬切换、软切换、重定向、重定位或小区更新等。In this embodiment, the wireless access capability update request of the user equipment is satisfied by transferring the user equipment to another area.
