具体实施方式
使用LTE eNB与NR gNB以紧耦合互操作的方式来为用户设备(User Equipment，UE)提供通信服务的系统架构参见图1，两个网元在无线接口上同时为所述UE提供通信服务，下文中，将为UE建立与核心网间唯一的控制面接口的服务网元称为第一网元，为UE提供额外的无线资源的服务网元称为第二网元，第一网元还为UE建立与核心网间的用户面(User Plane，UP)接口，第二网元与核心网间的UP接口是可选的。
在无线接口方面，第一网元使用第一RAT如LTE RAT、第二网元使用第二 RAT如NR RAT。一些示例中，第一网元、第二网元与UE间都会进行UP的数据传输；第一网元与UE间还建立第一RAT的信令无线承载(Signalling Radio Bearer，SRB)以传输控制面信令，如传输无线资源控制(Radio Resource Control，RRC)信令，而第二网元与UE间建立第二RAT的SRB是可选的。下文中，也将第一RAT的SRB称之为第一SRB，第二RAT的SRB称之为第二SRB。
从无线资源管理(Radio Resource Management，RRM)的角度来讲，第一网元负责为UE作出对第一RAT无线资源的配置，称之为第一配置，第二网元负责为UE作出对第二RAT无线资源的配置，称之为第二配置。所述两个配置彼此独立、又同时满足一定的范围(如两个配置之和不能超过UE的无线能力)。
在相关技术中，当处于RRC连接态(RRC_Connected)的UE无法接受服务网元所下达的无线资源配置时(即出现配置失败的情况)，UE会触发一个恢复的程序如RRC连接重建立(RRC Connection Re-establishment)程序。但是，这会造成用户面的数据传输中断，增加UE执行程序的复杂度和控制面的信令传输负荷。即使所述恢复程序成功执行，也需要一定的时间恢复无线接口上的数据传输。因此，图1所示的系统中，如紧耦合互操作的系统中，如何处理无线资源配置失败，从而提高UE的用户体验，是一个问题。
一些实施例涉及UE侧的无线资源配置。
所基于的系统架构参见图1及其说明，一些实施例中，第一网元和第二网元在无线接口上同时为所述UE提供通信服务，采用紧耦合互操作的方式，第一网元为所述UE建立与核心网间唯一的控制面接口。第一网元与UE间建立第一RAT的SRB，第二网元与UE间没有建立第二RAT的SRB。一些实施例中，第一网元使用的第一RAT是LTE RAT和NR RAT中的一种，第二网元使用的第二RAT是LTE RAT和NR RAT中的另一种，第一RAT不同于第二RAT即可。一些实施例中，第一网元和第二网元分别是eNB和gNB。
一实施例提供了无线资源配置方法，如图2所示，该方法包括以下步骤。
步骤110中，UE从第一无线接入技术RAT的信令无线承载SRB接收无线资源配置的第一消息，其中，所述第一消息携带第二配置的信息，以及所述第二配置是对第二RAT无线资源的配置。
一些实施例中，所述无线资源配置的第一消息是用于进行无线资源配置的任何消息，如RRC连接重配置(RRC Connection Reconfiguration)消息。
该方法实施例中，所述第一RAT的SRB是使用第一RAT的第一网元与所述UE间建立的SRB，所述第二配置是使用第二RAT的第二网元为所述UE所作的配置。
一些实施例中，所述无线资源配置的第一消息还携带第一配置的信息，所述第一配置是所述第一网元为所述UE作出的对第一RAT无线资源的配置。
一些实施例中，所述无线资源配置方法还包括：所述UE根据所述第一配置的信息配置第一RAT无线资源成功时，在发送的所述无线资源配置的响应消息中携带第一RAT无线资源配置成功的指示信息。一些实施例中，指示第一RAT无线资源配置成功的信息与第二RAT无线资源配置失败的上报信息携带在一条RRC信令中。一些实施例中，指示第一RAT无线资源配置成功的信息与第二RAT无线资源配置失败的上报信息携带在不同的RRC信令中。
步骤120中，所述UE根据所述第二配置的信息配置第二RAT无线资源失败时，发送无线资源配置的响应消息以指示第二RAT无线资源配置失败。
一些实施例中，上述无线资源配置的响应消息是任何用于对接收到的无线资源配置的消息做出响应的消息，如RRC连接重配置完成(RRC Connection Reconfiguration Complete)消息、辅小区组失败信息(Secondary Cell Group(SCG)Failure Information)消息或者其他RRC消息。一些实施例中，其他RRC消息为UE发送给基站的RRC消息，如第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)技术规范(Technical Specification，TS)38.331 V15.0.0(2017-12)中UE发送给基站的RRC消息(如RRC连接恢复(connection resume)消息)。
一些实施例中，所述无线资源配置的响应消息携带第二RAT无线资源配置失败的上报信息，所述上报信息包括以下至少一种信息：

一些实施例中，UE对第二RAT无线资源配置失败的指示是显性指示。一些实施例中，UE对第二RAT无线资源配置失败的指示是隐性指示。当UE对第二RAT无线资源配置失败的指示是显性指示时，响应消息中包含第二RAT无线资源配置失败的指示信息。当UE对第二RAT无线资源配置失败的指示是隐性指示时，响应消息中不包含第二RAT无线资源配置失败的指示信息，网络侧网元根据辅助信息(如失败原因和所述第二配置中无法运用的配置部分中至少之一)确定UE配置第二RAT无线资源失败，或者约定在没有收到第二RAT无线资源配置成功的指示信息时，即认为是第二RAT无线资源配置失败。
一些实施例中，所述第二RAT无线资源配置失败的所述上报信息采用第一RAT对应的抽象语法标记(Abstract Syntax Notation.one，ASN.1)进行编码，所述UE通过第一RAT的SRB发送所述无线资源配置的响应消息，将所述上报信息上报给所述第一网元处理。但在另一些实施例中，所述第二RAT无线资源配置失败的所述上报信息采用第二RAT对应的抽象语法标记ASN.1进行编码，所述UE通过第一RAT的SRB发送所述无线资源配置的响应消息，将所述上报信息携带在所述响应消息的容器中，通过所述第一网元转发给所述第二网元处理。一些实施例中，第一RAT对应的ASN.1和第二RAT对应的ASN.1是不同的，当第二RAT无线资源配置失败后由第一网元进行无线资源管理决策时，使用第一RAT对应的ASN.1对上报信息编码；当第二无线资源配置失败后由第二网元进行无线资源管理决策时，使用第二RAT对应的ASN.1对上报信息编码，编码后的上报信息携带在容器中，第一网元不对容器做处理直接转发给第二网元。

下面几个实施例对无线资源配置的信令流程进行说明。
一些实施例中，在无线接口上使用第一RAT的第一网元和使用第二RAT的第二网元以紧耦合互操作的方式为UE提供通信服务，其中，第一网元为UE建立与核心网间的控制面接口。在无线接口上，UE与第一网元间建立信令无线承载(第一SRB)以进行控制面信令的传输。一些实施例中，UE与第一网元间还进行用户面的数据传输，UE与第二网元间仅进行用户面的数据传输。
一些实施例中的无线资源配置方法的流程如图9所示，所述方法包括以下步骤。
步骤101中，根据无线资源的配置需求，当第二网元对UE所使用的第二RAT无线资源作出第二配置时，第二网元将所述第二配置通过网元间接口发送 给第一网元。其中，所述第二配置以第二RAT对应的ASN.1进行编码，可携带在网元间接口消息的一个容器(container)中。一些实施例中，所述无线资源的配置需求是第二网元根据其自身的无线资源管理决策而作出的。一些实施例中，所述无线资源的配置需求是根据接收到的来自第一网元的请求消息而作出的。
步骤102中，第一网元接收到所述第二配置后，生成相应的RRC信令，如RRC连接重配置(RRC Connection Reconfiguration)消息。一些实施例中，所述RRC连接重配置消息中包括第一网元对UE所使用的第一RAT无线资源所作出第一配置。一些实施例中，以第一RAT对应的ASN.1进行编码的第一配置与第二配置相对独立。一些实施例中，以第一RAT对应的ASN.1进行编码的第一配置与第二配置具有相关性。第一网元通过第一SRB将所述RRC Connection Reconfiguration消息发送给UE。
步骤103中，UE接收到所述RRC连接重配置消息后，根据消息中携带的第一配置、第二配置分别进行第一RAT无线资源、第二RAT无线资源配置。如果UE对第一RAT无线资源配置成功、而第二RAT无线资源配置失败，那么，UE在向第一网元回复的RRC信令(如RRC连接重配置完成(RRC Connection Reconfiguration Complete)消息)中至少指示UE对第一RAT无线资源配置成功的信息，所述信息以第一ASN.1进行编码。
一些实施例中，所述RRC连接重配置完成消息中还携带指示UE对第二RAT无线资源配置失败的信息。
一些实施例中，所述RRC连接重配置完成消息中还携带辅助信息，所述辅助信息中包括以下至少之一：

哪个无线资源无法配置；以及
哪些无线资源无法配置。
一些实施例中，所述辅助信息中还包括UE根据第一网元对第二RAT的测量配置执行测量而获得的结果。
所述UE对第二RAT无线资源配置失败的指示信息和所述辅助信息以第一ASN.1进行编码。
一些实施例中，所述UE对第二RAT无线资源配置失败的指示信息和所述辅助信息仅被携带在SCG失败信息(Failure Information)消息中。一些实施例 中，所述指示信息和所述辅助信息仅被携带在UE发送给基站的RRC消息，如3GPP TS 38.331 V15.0.0(2017-12)中UE发送给基站的RRC消息(如RRC连接恢复(connection resume)消息)中。
步骤104中，第一网元接收到所述UE对第二RAT无线资源配置失败的指示信息后进行无线资源管理决策，所述决策的结果是释放第二网元、或将第二网元由源第二RAT节点切换至目标节点、或通知第二网元进行第二RAT的无线资源重配置。一些实施例中，释放第二网元或切换第二网元的程序参考标准3GPP TS37.340。
一些实施例中，在UE回复的RRC信令中含有所述辅助信息时，第一网元参考所述辅助信息进行决策；如果所述辅助信息中没有包括测量结果，那么第一网元参考最近一次从UE接收到的测量结果进行决策。一些实施例中，所述第一网元通知第二网元进行第二RAT无线资源重配置的程序中，第一网元将所述辅助信息发送给第二网元。
一些实施例所依据的系统架构同图9所在的实施例的系统架构相同，该实施例中的无线资源配置方法如图10所示，该方法包括以下步骤。
步骤201-202，同上述实施例中的步骤101-102，第一网元对RRC信令的发送、UE接收与配置的情况均图9所在实施例的阐述。
步骤203中，UE在响应消息中对第二RAT无线资源配置失败的指示信息和所述辅助信息的编码以第二ASN.1进行编码。一些实施例中，以第二ASN.1进行编码的所述UE对第二RAT无线资源配置失败的指示信息和所述辅助信息携带在UE向第一网元回复的RRC信令内的容器(container)中。
一些实施例中，如果所述辅助信息中包含测量结果，那么所述测量结果是UE根据第二网元的测量配置执行测量而获得的结果。
步骤204中，第一网元接收到来自UE的RRC信令后，对所述信令中携带的与第二RAT相关的容器(container)不做解读及相应的判决，而是将所述容器(container)通过网元间接口传输给第二网元。
步骤205中，第二网元接收到所述容器(container)后，根据其中指示的信息进行第二RAT相关的无线资源管理决策。一些实施例中，所述无线资源管理决策是释放第二网元。一些实施例中，所述无线资源管理决策为切换至目标第二RAT节点。一些实施例中，无线资源管理决策为重配置第二RAT无线资源。 一些实施例中，第二网元触发的释放第二网元或切换第二网元的程序参考标准3GPP TS37.340。
一些实施例中，如果所述容器(container)中含有所述辅助信息，那么第二网元参考所述辅助信息进行决策；如果所述辅助信息中没有包括测量结果，那么，第二网元参考最近一次获取到的测量结果进行决策。
一些实施例中，当第二网元的无线资源管理决策结果是进行第二RAT无线资源的重配置时，第二网元将对UE所使用的第二RAT无线资源作出的重配置(称为第二重配置)通过网元间接口发送给第一网元，第一网元生成相应的RRC信令通过第一SRB发送给UE。一些实施例中，如果第一SRB配置为MCG分离(split)的承载类型，那么所述RRC信令承载在MCG分离(split SRB)上发送给UE。
一些实施例中，在无线接口上使用第一RAT的第一网元和使用第二RAT的第二网元以紧耦合互操作的方式为UE提供通信服务，其中，第一网元为UE建立与核心网间的控制面接口。在无线接口上，UE与第一网元、第二网元间分别建立信令无线承载(第一、第二SRB)以进行控制面信令的传输，同时，UE与第一网元、第二网元间进行用户面的数据传输。
一些实施例中的无线资源配置方法的流程如图11所示，该方法包括以下步骤。
步骤301中，根据无线资源的配置需求，当第二网元对UE所使用的第二RAT无线资源作出第二配置时，第二网元对所述第二配置生成相应的RRC信令(如RRC连接重配置(Connection Reconfiguration)消息)、并通过第二SRB发送给UE。其中，所述第二配置以第二ASN.1进行编码，对UE所使用的第一RAT无线资源没有即时的影响。
步骤302中，UE接收到所述RRC连接重配置(Connection Reconfiguration)消息后，根据消息中携带的第二配置对第二RAT无线资源进行配置。如果UE对所述配置执行失败，那么，UE向第二网元回复控制面消息，所述控制面消息中携带指示UE执行第二配置失败的信息。
一些实施例中，所述控制面消息中还携带辅助信息，所述辅助信息中包括以下至少之一：
UE执行第二配置失败的原因、哪个第二配置无法执行、以及；哪部分第二 配置无法执行。一些实施例中，所述辅助信息中还包括UE根据第二网元的测量配置执行测量而获得的结果。
所述UE执行第二配置失败的指示信息和所述辅助信息以第二ASN.1进行编码。
一些实施例中，所述控制面消息是RRC连接重配置(Connection Reconfiguration Complete)消息、或SCG失败信息(Failure Information)消息、或其他RRC信令。一些实施例中，其他RRC信令为UE发送给基站的RRC信令，如3GPP TS 38.331 V15.0.0(2017-12)中UE发送给基站的RRC信令(如RRC连接恢复(connection resume)信令)中。
所述控制面消息通过第二RAT的CCCH上报给第二网元。
一些实施例中，所述控制面消息通过第一SRB上报给第一网元、再由第一网元通过网元间接口消息转发给第二网元。在这种传输路径下，所述指示UE执行第二配置失败的信息和所述辅助信息携带在所述控制面消息和所述网元间接口消息的容器(container)中。
步骤303中，接收到所述UE执行第二配置失败的指示信息后，第二网元进行第二RAT相关的无线资源管理决策。所述决策结果与依据同上述步骤203所述。
一些实施例所依据的系统架构同图11所在实施例的系统架构，这些实施例中的方法的流程如图12所示，所述方法包括以下步骤。
步骤401同步骤301。
步骤402中，UE执行第二配置失败的指示信息和所述辅助信息的编码形式，其中，所述UE执行第二配置失败的指示信息和所述辅助信息以第一ASN.1进行编码。UE将所述控制面消息通过第一SRB上报给第一网元。
步骤403中，第一网元接收到所述控制面消息后的无线资源管理决策同步骤104。
在上述实施例的所述系统架构中，当UE无法接受对应第二网元的第二无线资源配置时，通过上述方案，避免了对对应第一网元的第一无线资源配置的影响、以及无线接口的重建立等程序，从而避免了用户面的数据传输中断、减轻了UE执行程序的复杂度、也减少了控制面的信令传输负荷，提高了系统性能。
