综上所述, 本申请实施例中, 在 UE从 3GPP 网络切换到非 3GPP 网络时, 基站设备会维护 UE在非 3GPP网络中的上下文信息, 使得基 站设备能够利用 UE在非 3GPP网络中的上下文信息进行相关处理(如: 基站设备利用 UE在非 3GPP网络中的上下文信息确定是否进行测量配 置和 /或是否进行业务切换等处理;), 从而可以解决切换过程中如何使用 UE在非 3GPP 网络中的上下文信息的问题, 并可以使系统能够正常工 作。 In summary, in the embodiment of the present application, when the UE switches from the 3GPP network to the non-3GPP network, the base station device maintains the context information of the UE in the non-3GPP network, so that the base station device can utilize the context of the UE in the non-3GPP network. The information is processed in a related manner (for example, the base station device determines whether to perform measurement configuration and/or whether to perform service switching, etc. by using context information of the UE in the non-3GPP network), so as to solve how the UE is used in the non-3GPP network during the handover process. The problem of contextual information and can make the system work properly.
以下结合具体的网络场景对本申请实施例进行进一步的说明。 The embodiments of the present application are further described below in conjunction with specific network scenarios.
本实施例中, 基站设备利用 WLAN context (即 UE在 WLAN中的 上下文信息)进行测量配置和业务切换, 具体的网络场景如图 3所示, 基站设备可以是 UMTS的 RNC,也可以是 LTE的 eNB,接入点为 WLAN 的 AP。 In this embodiment, the base station device uses the WLAN context (that is, the context information of the UE in the WLAN) to perform measurement configuration and service switching. The specific network scenario is shown in FIG. 3, and the base station device may be an RN of the UMTS or an LTE. eNB, the access point is an AP of the WLAN.
本应用场景下, UE 只和基站设备有连接, 并有三个业务在传输, 分别承载在 DRB1、 DRB 2和 DRB3上。 随着 UE移动到接入点 1的覆 盖范围, 基站设备判决将业务 1 ( DRB1上承载)切换到 WLAN上进行 传输, 并向 UE发送承载切换命令。 UE收到命令后, 将业务 1切换到接 入点 1, 并进一步保存业务 1和 DRB1的对应关系。 当 UE成功完成业 务 1的切换后,核心网会向基站设备发送释放该 UE的业务 1对应的 EPS 承载的命令, 基站设备收到该命令后, 释放相应承载对应的资源, 但是 仍保存 UE当前的 WLAN context,即 UE的业务 1在 WLAN,进一步的, 该业务切换前对应的承载是 DRB 1。
由于基站设备知道目前 UE有业务在 WLAN传输, 因此基站设备为 UE配置对 WLAN的测量(如信道质量或者负载信息的测量), 在本实 施例中配置的测量事件为" WLAN的信道质量低于门限"。 后续过程中, UE需要按照测量配置信息对 WLAN进行监测, 当 UE朝接入点 1覆盖 范围外移动时,且该 UE测量到的 WLAN信道质量低于基站设备配置的 门限后, 会触发 UE进行测量上报, 即将该信息上报给基站设备。 基站 设备在收到测量上报之后, 结合 UE当前的 WLAN context信息( UE的 业务 1在 WLAN ), 基站设备会向 UE发送承载切换命令, 以将业务 1 从 WLAN切换回基站设备。进一步的, 该基站设备还可以重新为 UE配 置 DRB1用于传输该业务 1。 In this application scenario, the UE is only connected to the base station device, and three services are transmitted, and are respectively carried on DRB1, DRB 2, and DRB3. As the UE moves to the coverage of the access point 1, the base station device decides to switch the service 1 (the bearer on the DRB1) to the WLAN for transmission, and sends a bearer handover command to the UE. After receiving the command, the UE switches the service 1 to the access point 1, and further stores the correspondence between the service 1 and the DRB1. After the UE successfully completes the handover of the service 1, the core network sends a command to the base station device to release the EPS bearer corresponding to the service 1 of the UE. After receiving the command, the base station device releases the resource corresponding to the bearer, but still saves the current UE. The WLAN context, that is, the service 1 of the UE is in the WLAN, and further, the corresponding bearer before the service handover is DRB 1. Since the base station device knows that the UE currently has a service in the WLAN, the base station device configures the measurement of the WLAN (such as the measurement of the channel quality or the load information) for the UE. The measurement event configured in this embodiment is “the channel quality of the WLAN is lower than Threshold". In the subsequent process, the UE needs to monitor the WLAN according to the measurement configuration information. When the UE moves outside the coverage of the access point 1 and the WLAN channel quality measured by the UE is lower than the threshold configured by the base station, the UE is triggered. The measurement is reported, that is, the information is reported to the base station device. After receiving the measurement report, the base station device combines the current WLAN context information of the UE (the service 1 of the UE is in the WLAN), and the base station device sends a bearer handover command to the UE to switch the service 1 from the WLAN back to the base station device. Further, the base station device may further configure the DRB1 for the UE to transmit the service 1.
综上所述, 基站设备通过保存 UE的 WLAN context, 实现了合理的 测量配置和切换决策, 保证了 UE业务的连续性, 保障了用户体验。 In summary, the base station device implements a reasonable measurement configuration and handover decision by preserving the WLAN context of the UE, ensuring the continuity of the UE service and ensuring the user experience.
本实施例中, 基站设备利用 WLAN context (即 UE在 WLAN中的 上下文信息)在切换过程中进行 WLAN context的传递, 具体的网络场 景如图 4所示, 基站设备可以是 UMTS的 RNC或是 LTE的 eNB, 接入 点为 WLAN的 AP。 In this embodiment, the base station device uses the WLAN context (that is, the context information of the UE in the WLAN) to perform the WLAN context transmission in the handover process. The specific network scenario is shown in FIG. 4, and the base station device may be the UMTS RNC or the LTE. The eNB, the access point is the AP of the WLAN.
UE最初在基站设备 1和接入点 1的覆盖范围之内, 同时与基站设 备 1和接入点 1保持了连接。 其中, UE上具有三个业务, 业务 1在基 站设备 1传输, 且业务 2和业务 3在 WLAN传输; 进一步的, 基站设 备 1和 UE均需要保留 UE的 WLAN context信息, 即业务 2和业务 3 在 WLAN传输。 The UE is initially within the coverage of base station device 1 and access point 1 while maintaining a connection with base station device 1 and access point 1. The UE has three services, the service 1 is transmitted on the base station device 1, and the service 2 and the service 3 are transmitted on the WLAN. Further, the base station device 1 and the UE need to retain the WLAN context information of the UE, that is, the service 2 and the service 3 Transmission on WLAN.
随着 UE的移动, UE从基站设备 1 的覆盖范围进入到基站设备 2 的覆盖范围, 此时基站设备 1基于判决 UE从基站设备 1向基站设备 2 进行切换, 然后基站设备 1向基站设备 2发送切换请求消息, 且在该切 换请求消息中,基站设备 1携带 UE当前的 WLAN context (业务 2和业
务 3在 WLAN传输), 以及 UE的 3GPP业务 context (业务 1在基站设 备 1传输)。 As the UE moves, the UE enters the coverage of the base station device 2 from the coverage of the base station device 1, and the base station device 1 switches from the base station device 1 to the base station device 2 based on the decision UE, and then the base station device 1 moves to the base station device 2 Sending a handover request message, and in the handover request message, the base station device 1 carries the current WLAN context of the UE (service 2 and industry) Traffic 3 is transmitted over the WLAN, and the 3GPP service context of the UE (Service 1 is transmitted at the base station device 1).
基站设备 2收到切换请求消息后, 如果判决切换业务 1, 则在切换 命令中携带将业务 1切换到基站设备 2的信息, 由基站设备 1将切换命 令透传给 UE。 UE收到切换命令后, 基于其中携带的将业务 1切换到基 站设备 2的信息, UE将业务 1切换到基站设备 2, 并且仍然保持业务 2 和业务 3在 AP传输。 After receiving the handover request message, the base station device 2 carries the information for switching the service 1 to the base station device 2 in the handover command, and the base station device 1 transparently transmits the handover command to the UE. After receiving the handover command, the UE switches the service 1 to the base station device 2 based on the information carried in the handover of the service 1 to the base station device 2, and still keeps the service 2 and the service 3 transmitted at the AP.
如果基站设备 1没有在切换过程中将 UE的 WLAN context传递给目 标基站设备(即基站设备 2 ), 或者在基站设备 1发送切换命令后, UE 的 WLAN context发生改变了 (比如业务 2结束), 则当 UE成功接入到 目标基站设备(即基站设备 2 )之后,还需要将自身当前的 WLAN context 通知给基站设备 2。 If the base station device 1 does not transmit the WLAN context of the UE to the target base station device (ie, the base station device 2) during the handover process, or after the base station device 1 sends the handover command, the WLAN context of the UE changes (for example, the service 2 ends), Then, after the UE successfully accesses the target base station device (ie, the base station device 2), it also needs to notify the base station device 2 of its current WLAN context.
UE成功切换到基站设备 2之后,后续基站设备 2与 UE的处理方式 均与图 3所示实施例中的相关处理相同, 后续相关过程本实施例中不再 重复赘述。 After the UE successfully switches to the base station device 2, the processing manners of the subsequent base station device 2 and the UE are the same as those in the embodiment shown in FIG. 3, and the subsequent related processes are not repeatedly described in this embodiment.
本实施例中, UE上报当前的 WLAN context (即 UE在 WLAN中的 上下文信息),具体的网络场景可以如图 3所示,基站设备可以是 UMTS 的 RNC, 也可以是 LTE的 eNB, 接入点为 WLAN的 AP。 In this embodiment, the UE reports the current WLAN context (that is, the context information of the UE in the WLAN). The specific network scenario may be as shown in FIG. 3, and the base station device may be an RN of the UMTS or an eNB of the LTE. The point is the WLAN AP.
UE首先在 WLAN建立连接, 并且在 WLAN传输业务 1和业务 2。 后续 UE又与基站设备 1建立了连接,并传输业务 3。在 UE与基站设备 1建立连接之后, UE通过 RRC专用信令主动向基站设备 1上报当前的 WLAN context, 基站设备 1在收到 UE当前的 WLAN context后, 需要 保存该 WLAN context。或者,基站设备 1向 UE发送请求上报其 WLAN context的 RRC专用信令, UE在收到该 RRC专用信令后, 上报相关信 息 (即当前的 WLAN context ), 基站设备 1在收到 UE当前的 WLAN
context后, 需要保存该 WLAN context。 The UE first establishes a connection on the WLAN and transmits Service 1 and Service 2 on the WLAN. The subsequent UE establishes a connection with the base station device 1 and transmits the service 3. After the UE establishes a connection with the base station device 1, the UE actively reports the current WLAN context to the base station device 1 through the RRC dedicated signaling. After receiving the current WLAN context of the UE, the base station device 1 needs to save the WLAN context. Alternatively, the base station device 1 sends an RRC dedicated signaling requesting the WLAN context to the UE, and after receiving the RRC dedicated signaling, the UE reports the related information (ie, the current WLAN context), and the base station device 1 receives the current UE. WLAN After the context, you need to save the WLAN context.
其中, WLAN context可以包括是否有 WLAN业务(如 lbit表示是 否有 WLAN业务); 进一步的, 当有 WLAN业务时, 该 WLAN context 还可以包括具体的业务信息,该业务信息可以包括业务个数、业务标识、 QCI等 等。 The WLAN context may include whether there is a WLAN service (for example, lbit indicates whether there is a WLAN service). Further, when there is a WLAN service, the WLAN context may further include specific service information, where the service information may include the number of services and services. Logo, QCI, etc.
基站设备 1在收到上述 WLAN context之后的, 后续基站设备 1与 UE的处理方式与图 3所示实施例中的处理相同, 后续相关过程本实施 例中不再重复赘述。 After the WLAN context is received by the base station device 1, the processing manners of the subsequent base station device 1 and the UE are the same as those in the embodiment shown in FIG. 3, and the subsequent related processes are not repeatedly described in this embodiment.
