Description
技术领域 technical field
本发明涉及无线通信技术领域,特别涉及终端状态迁移的判别方法及设备。The invention relates to the technical field of wireless communication, in particular to a method and equipment for judging terminal state transition.
背景技术 Background technique
在无线通信系统中,UE(User Equipment,终端设备)的状态迁移由RAN(Radio AccessNetwork,无线接入网络)设备根据UE的流量和迟滞(未传输数据)时长进行判决,上述流量和迟滞时长采用统一设置的经验值。其中,UE迁移的状态包括IDLE(空闲)状态、DCH(Dedi cated Channel,专用信道)状态和HSPA(Hi gh Speed Packet Access,高速数据接入)状态。In a wireless communication system, the UE (User Equipment, terminal equipment) state transition is judged by the RAN (Radio Access Network, wireless access network) device according to the UE's traffic and hysteresis (data not transmitted) duration. The experience value of the unified setting. Among them, the state of UE migration includes IDLE (idle) state, DCH (Dedicated Channel, dedicated channel) state and HSPA (High Speed Packet Access, high-speed data access) state.
现有技术中采用流量和迟滞时长对UE的状态迁移进行监控,但是,当UE实现支持分段的流传输业务时,例如,UE通过网页浏览网站视频时,会通过HTTP(HypertextTransfer Protocol,超文本传输协议)STREAM(流传输)协议,采用高速速率进行视频数据的无线传输,并对视频数据进行缓存,在缓存了一定量视频数据后,UE会关闭无线传输功能,以便节约UE的电能,待缓存的视频数据将播放完时,再启动无线传输功能,以便继续进行视频数据的无线传输,重复上述过程,直至浏览完所有视频数据。In the prior art, traffic and lag time are used to monitor the state transition of the UE. However, when the UE implements a segmented stream transmission service, for example, when the UE browses a website video through a web page, it will pass HTTP (HypertextTransfer Protocol, hypertext Transmission protocol) STREAM (stream transmission) protocol, which uses high-speed wireless transmission of video data and caches the video data. After a certain amount of video data is cached, the UE will turn off the wireless transmission function in order to save the power of the UE. When the buffered video data is finished playing, the wireless transmission function is started again, so as to continue the wireless transmission of the video data, and the above process is repeated until all the video data are browsed.
发明人在对现有技术的研究过程中发现,UE在实现支持分段的流传输业务的过程中,由于数据传输量的变化,会自动进行状态迁移,上述自动状态迁移的时间往往小于RAN设备监测的迟滞时间,因此UE从原状态迁移到下一状态时,RAN设备难以检测到UE实际的状态,且由于RAN设备仍然会为监测UE状态迁移分配码资源和功率资源,由此浪费了网络监控资源。In the process of researching the prior art, the inventor found that in the process of realizing the stream transmission service that supports segments, due to the change of the data transmission volume, the UE will automatically perform the state transition, and the time of the above-mentioned automatic state transition is often shorter than that of the RAN equipment The monitoring lag time, so when the UE transitions from the original state to the next state, it is difficult for the RAN device to detect the actual state of the UE, and because the RAN device will still allocate code resources and power resources for monitoring the UE state transition, thus wasting the network Monitor resources.

具体实施方式 Detailed ways
本发明如下实施例提供了终端状态迁移的判别方法及设备。The following embodiments of the present invention provide a method and equipment for judging terminal state transition.
为了使本技术领域的人员更好地理解本发明实施例中的技术方案,并使本发明实施例的上述目的、特征和优点能够更加明显易懂,下面结合附图对本发明实施例中技术方案作进一步详细的说明。In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings For further detailed explanation.
本发明实施例涉及终端状态迁移的判别,参见图1A,为UE的状态迁移示意图:The embodiment of the present invention relates to the discrimination of terminal state transition, see FIG. 1A, which is a schematic diagram of UE state transition:
本发明实施例中UE的状态包括IDLE状态、DCH状态和HSPA状态。现有技术中在对UE的状态迁移进行判别时,采用统一的迟滞时长判别条件和流量变化判别条件,具体的判别过程包括:当UE处于IDLE状态时,UE与RAN设备之间没有业务流量,当RAN设备监测到出现业务流量时,判别UE迁入DCH状态;当UE处于DCH状态时,RAN设备监测到网络侧对UE的缓存数据超过预设数量(上行256Byte,下行512Byte)时,判别UE迁入HSPA状态;当UE处于HAPA状态时,RAN设备监测到UE在20秒内没有数据传输时,判别UE迁入DCH状态;当UE处于DCH状态时,RAN设备监测到UE在30分钟内没有数据传输时,判别UE迁入IDLE状态。The state of the UE in the embodiment of the present invention includes an IDLE state, a DCH state and an HSPA state. In the prior art, when judging the state transition of the UE, a unified hysteresis time length judging condition and a traffic change judging condition are adopted. The specific judging process includes: when the UE is in the IDLE state, there is no traffic between the UE and the RAN device, When the RAN device detects service traffic, it will determine that the UE has moved into the DCH state; when the UE is in the DCH state, the RAN device will detect that the buffer data of the UE on the network side exceeds the preset amount (uplink 256Byte, downlink 512Byte), and determine the UE Move into the HSPA state; when the UE is in the HAPA state, the RAN device detects that the UE has no data transmission within 20 seconds, and judges that the UE has moved into the DCH state; when the UE is in the DCH state, the RAN device detects that the UE has not transmitted data within 30 minutes During data transmission, it is determined that the UE moves into the IDLE state.
上述在从HSPA状态向IDLE状态迁移的过程中,RAN设备采用迟滞时长判别条件对UE的状态迁移进行判别,但是UE在实现支持分段的流传输业务的过程中,由于数据传输量的变化,会自动进行状态迁移,如图1A中所示,UE会自动从HSPA状态迁移到IDLE状态,或者从DCH状态迁移到IDLE状态,上述UE进行自动状态迁移的时间往往小于RAN设备监测的迟滞时间,导致RAN设备难以判别出UE的真实状态。因此,本发明实施例通过预先为支持分段的流传输业务设置状态迁移判别条件,以实现对访问的业务为支持分段的流传输业务的UE的状态迁移进行准确判别。In the process of transitioning from the HSPA state to the IDLE state above, the RAN device uses the hysteresis duration judgment condition to judge the state transition of the UE. The state transition will be performed automatically. As shown in FIG. 1A, the UE will automatically transition from the HSPA state to the IDLE state, or from the DCH state to the IDLE state. The time for the above-mentioned UE to perform automatic state transition is often less than the lag time monitored by the RAN equipment. As a result, it is difficult for the RAN device to determine the real state of the UE. Therefore, the embodiments of the present invention set the state transition judgment condition for the stream transmission service supporting the segment in advance, so as to realize the accurate judgment of the state transition of the UE whose accessed service supports the stream transmission service of the segment.
参见图1B,为本发明终端状态迁移的判别方法的第一实施例流程图,该实施例流程可以由无线网络中的RAN设备执行:Referring to FIG. 1B, it is a flow chart of the first embodiment of the method for discriminating the terminal state transition of the present invention, and the flow of this embodiment can be executed by the RAN device in the wireless network:
步骤101:识别UE访问的业务为支持分段的流传输业务。Step 101: Identify that the service accessed by the UE is a segmented stream transmission service.
本实施例中支持分段的流传输业务通常属于PS(Packet Switch,数据交换)业务,PS业务包括流媒体业务、VOIP(Voice over Internet Protocol,语音网络协议传输)业务等等。In this embodiment, the segmented stream transmission service generally belongs to PS (Packet Switch, data switching) service, and PS service includes streaming media service, VOIP (Voice over Internet Protocol, voice network protocol transmission) service and the like.
在识别UE访问的业务时,获取UE所访问的业务的业务识别信息,判断UE所访问的业务的业务识别信息与预先保存的支持分段的流传输业务的业务识别信息是否匹配,当判断结果为匹配时,确定UE访问的业务为支持分段的流传输业务。When identifying the service accessed by the UE, obtain the service identification information of the service accessed by the UE, and judge whether the service identification information of the service accessed by the UE matches the service identification information of the pre-saved stream transmission service that supports segmentation, and when the judgment result When no match, determine that the service accessed by the UE is a stream transmission service that supports segmentation.
其中,UE所访问的业务的业务识别信息包括至少一种下述信息:用于标识UE所访问的业务的网络地址的URL(Uniform Resource Locator,统一资源定位符信息);用于标识UE所访问的业务的业务类型的DPI(Deep Packet Inspection,深度包识别)信息。相应的,在获取所述UE所访问的业务的业务识别信息时,可以从所述UE向所访问的业务所在服务器发送的HTTP请求中获取UE所访问的业务的URL信息,也可以从所述UE与所访问的业务所在服务器之间传输的流协议协商消息中获取所述UE所访问的业务的DPI信息。Wherein, the service identification information of the service accessed by the UE includes at least one of the following information: a URL (Uniform Resource Locator, uniform resource locator information) used to identify the network address of the service accessed by the UE; DPI (Deep Packet Inspection, deep packet identification) information of the business type of the business. Correspondingly, when obtaining the service identification information of the service accessed by the UE, the URL information of the service accessed by the UE may be obtained from the HTTP request sent by the UE to the server where the service is accessed, or from the The DPI information of the service accessed by the UE is acquired from a stream protocol negotiation message transmitted between the UE and the server where the accessed service resides.
步骤102:采用预先为支持分段的流传输业务设置的状态迁移判别条件对UE的状态迁移进行判别。Step 102: Discriminate the state transition of the UE by using the state transition discrimination condition set in advance for the stream transmission service supporting segmentation.
本实施例中,优选的预先为支持分段的流传输业务设置的状态迁移判别条件为预先为时间判别条件,该时间判别条件中设置的时间值小于现有时间判别条件中设置的时间值,该时间值即为现有技术中在判别UE状态迁移时的迟滞时间。例如,现有设置UE在30分钟内没有数据传输时,判别UE迁入IDLE状态,本实施例中可以设置UE在5分钟内没有数据传输时,判别UE迁入IDLE状态,以适应支持分段的流传输业务的数据传输特点,准确判别UE的状态迁移。In this embodiment, preferably, the pre-set state transition judgment condition for the stream transmission service that supports segmentation is a time judgment condition in advance, and the time value set in the time judgment condition is less than the time value set in the existing time judgment condition, This time value is the lag time when judging UE state transition in the prior art. For example, it is currently set that when the UE has no data transmission within 30 minutes, it is determined that the UE moves into the IDLE state. In this embodiment, it can be set that when the UE has no data transmission within 5 minutes, it is determined that the UE moves into the IDLE state, so as to adapt to support segmentation The data transmission characteristics of the stream transmission service can accurately judge the state transition of the UE.
具体的,判断UE在DCH状态或者HSPA状态时流传输业务的变化是否满足预设的状态迁移判别条件,当满足状态迁移判别条件时,确定UE从DCH状态或者HSPA状态迁移到空闲状态,当不满足状态迁移判别条件时,确定UE保持在DCH状态或者HSPA状态。Specifically, it is judged whether the change of the streaming service when the UE is in the DCH state or the HSPA state satisfies the preset state transition judgment condition. When the state transition judgment condition is satisfied, it is determined that the UE transitions from the DCH state or the HSPA state to the idle state. When the state transition judging condition is met, it is determined that the UE remains in the DCH state or the HSPA state.
由上述实施例可见,该实施例通过识别UE访问的业务为支持分段的流传输业务,然后采用为支持分段的流传输业务专门设置的状态迁移条件对UE的状态迁移进行判别,而不是采用现有状态迁移条件进行判别,因此可以检测到UE的实际迁移状态,避免了对网络监控资源的浪费。It can be seen from the above-mentioned embodiment that in this embodiment, by identifying that the service accessed by the UE is a stream transmission service that supports segmentation, and then using the state transition conditions specially set for the stream transmission service that supports segmentation, the state transition of the UE is judged instead of The existing state transition conditions are used for discrimination, so the actual transition state of the UE can be detected, and the waste of network monitoring resources is avoided.
参见图2,为本发明终端状态迁移的判别方法的第二实施例流程图,该实施例流程可以由无线网络中的RAN设备执行,该实施例详细示出了RAN设备根据URL信息进行支持分段的流传输业务的识别,并根据预设的时间判别条件对终端的状态迁移进行判别的过程:Referring to FIG. 2 , it is a flow chart of the second embodiment of the method for discriminating terminal state transition in the present invention. The flow of this embodiment can be executed by the RAN device in the wireless network. This embodiment shows in detail that the RAN device performs support analysis according to the URL information. The process of identifying the stream transmission service of a segment, and judging the state transition of the terminal according to the preset time judging conditions:
步骤201:预先保存支持分段的流传输业务的URL信息。Step 201: pre-store URL information of a streaming service that supports segmentation.
本实施例中,支持分段的流传输业务主要指基于HTTP STREAM协议的视频流传输业务,例如,现有常见的视频浏览网站所提供的视频在线观看就属于支持分段的流传输业务,对于网站所提供的每个视频都具有相应的URL地址,该URL地址标识了每个流传输业务的网络地址,因此RAN设备可以预先保存网络中所有支持分段的流传输业务的URL信息。In this embodiment, the stream transmission service that supports segmentation mainly refers to the video stream transmission service based on the HTTP STREAM protocol. For example, the online viewing of videos provided by existing common video browsing websites belongs to the stream transmission service that supports segmentation. Each video provided by the website has a corresponding URL address, and the URL address identifies the network address of each streaming service, so the RAN device can pre-store URL information of all segmented streaming services in the network.
步骤202:按照预设的时间周期更新保存的支持分段的流传输业务的URL信息。Step 202: Update the saved URL information of the stream transmission service supporting segments according to a preset time period.
由于无线网络中支持分段的流传输业务是不断变化的,因此可以按照预设的时间周期更新保存的支持分段的流传输业务的URL信息,例如,每周更新一次,或者每两周更新一次,以确保RAN设备可以根据URL信息准确识别UE所访问的业务是否为支持分段的流传输业务。Since the segmented streaming service in the wireless network is constantly changing, the saved URL information of the segmented streaming service may be updated according to a preset time period, for example, once a week or every two weeks Once, to ensure that the RAN device can accurately identify whether the service accessed by the UE is a segmented streaming service according to the URL information.
步骤203:从UE向所访问业务所在服务器发送的HTTP请求中获取UE所访问业务的URL信息。Step 203: Obtain the URL information of the service accessed by the UE from the HTTP request sent by the UE to the server where the service is accessed.
当UE通过访问视频网站想要对其中浏览的某个在线视频进行观看时,UE会向该视频所在的服务器发送HTTP请求,该HTTP请求中包含了待访问视频的URL地址,当该HTTP请求通过RAN设备传输时,RAN设备可以从中获取到该视频的URL地址。When the UE wants to watch an online video browsed by visiting a video website, the UE will send an HTTP request to the server where the video is located. The HTTP request contains the URL address of the video to be accessed. When the HTTP request passes When the RAN device transmits, the RAN device can obtain the URL address of the video from it.
步骤204:判断UE所访问业务的URL信息与预先保存的URL信息是否匹配,若匹配,则执行步骤205;否则,执行步骤209。Step 204: Judging whether the URL information of the service accessed by the UE matches the pre-stored URL information, and if they match, perform step 205; otherwise, perform step 209.
步骤205:确定UE访问的业务为支持分段的流传输业务。Step 205: Determine that the service accessed by the UE is a segmented stream transmission service.
RAN设备将获取到的URL信息与预先保存的URL信息进行匹配,当获取到的URL信息与预先保存的URL信息中的一个一致时,则说明UE访问的业务为支持分段的流传输业务。The RAN device matches the acquired URL information with the pre-stored URL information, and when the acquired URL information is consistent with one of the pre-stored URL information, it indicates that the service accessed by the UE is a streaming service that supports segmentation.
步骤206:判断UE处于DCH状态或者HSPA状态时流传输业务的变化是否满足预先设置的时间判别条件,若满足,则执行步骤207;否则,执行步骤208。Step 206: Judging whether the change of the streaming service when the UE is in the DCH state or the HSPA state satisfies the preset time discrimination condition, if so, execute step 207; otherwise, execute step 208.
结合图1A可知,UE在访问支持分段的流传输业务时可能进行自动状态迁移,该自动状态迁移包括从DCH状态迁移到IDLE状态,或者从HSPA状态迁移到IDLE状态,因此本实施例中判别UE处于DCH状态或者HSPA状态时流传输业务的变化是否满足预先设置的时间判别条件。It can be seen from FIG. 1A that UE may perform automatic state transition when accessing a streaming service that supports segmentation. The automatic state transition includes transition from DCH state to IDLE state, or transition from HSPA state to IDLE state. Therefore, in this embodiment, it is determined that When the UE is in the DCH state or the HSPA state, whether the change of the streaming service satisfies the preset time judgment condition.
其中,时间判别条件可以根据支持分段的流传输业务的特点进行设置,例如,设置时间判别条件为5分钟,即判断UE处于DCH状态或者HSPA状态时,在5分钟内如果没有数据传输,则说明UE处于DCH状态或者HSPA状态时流传输业务的变化满足预先设置的时间判别条件。Among them, the time discrimination condition can be set according to the characteristics of the stream transmission service that supports segments. For example, the time discrimination condition is set to 5 minutes, that is, when it is judged that the UE is in the DCH state or the HSPA state, if there is no data transmission within 5 minutes, then It shows that when the UE is in the DCH state or the HSPA state, the change of the streaming service satisfies the preset time discrimination condition.
步骤207:确定UE从DCH状态或者HSPA状态移到空闲状态,结束当前流程。Step 207: Determine that the UE moves from the DCH state or the HSPA state to the idle state, and end the current procedure.
流传输业务的变化满足预先设置的时间判别条件,则确定UE从DCH状态或者HSPA状态移到空闲状态。If the change of the stream transmission service satisfies the preset time discrimination condition, it is determined that the UE moves from the DCH state or the HSPA state to the idle state.
步骤208:确定UE保持在DCH状态或者HSPA状态,结束当前流程。Step 208: Determine that the UE remains in the DCH state or the HSPA state, and end the current process.
流传输业务的变化不满足预先设置的时间判别条件,则确定UE保持在DCH状态或者HSPA状态。If the change of the stream transmission service does not meet the preset time discrimination condition, it is determined that the UE remains in the DCH state or the HSPA state.
步骤209:采用现有状态迁移判别条件对UE的状态迁移进行确定,结束当前流程。Step 209: Determine the state transition of the UE by using the existing state transition judgment condition, and end the current process.
UE所访问业务的URL信息与预先保存的URL信息不匹配,说明UE访问的业务不是支持分段的流传输业务,因此RAN设备可以采用现有状态迁移判别条件对UE的状态迁移进行判别。If the URL information of the service accessed by the UE does not match the pre-saved URL information, it means that the service accessed by the UE is not a streaming service that supports segmentation. Therefore, the RAN device can use the existing state transition judgment conditions to judge the state transition of the UE.
由上述实施例可见,该实施例通过URL信息识别UE访问的业务为支持分段的流传输业务,然后采用为支持分段的流传输业务专门设置的时间判别条件对UE的状态迁移进行判别,而不是采用现有状态迁移条件进行判别,因此可以检测到UE在访问支持分段的流传输业务时的实际迁移状态,避免了对网络监控资源的浪费。It can be seen from the above embodiment that in this embodiment, the URL information is used to identify that the service accessed by the UE is a stream transmission service that supports segmentation, and then the state transition of the UE is judged by using the time discrimination condition specially set for the stream transmission service that supports segmentation. Instead of using the existing state transition conditions for discrimination, it is possible to detect the actual transition state of the UE when accessing the segmented stream transmission service, avoiding the waste of network monitoring resources.
参见图3,为本发明终端状态迁移的判别方法的第三实施例流程图,该实施例流程可以由无线网络中的RAN设备执行,该实施例详细示出了RAN设备根据DPI信息进行支持分段的流传输业务的识别,并根据预设的时间判别条件对终端状态迁移进行确定的过程:Referring to FIG. 3 , it is a flow chart of the third embodiment of the method for discriminating terminal state transition in the present invention. The flow of this embodiment can be executed by the RAN device in the wireless network. This embodiment shows in detail that the RAN device performs support analysis according to the DPI information. The process of identifying the stream transmission service of a segment, and determining the transition of the terminal state according to the preset time discrimination conditions:
步骤301:预先保存支持分段的流传输业务的DPI信息。Step 301: Pre-save the DPI information of the stream transmission service that supports segmentation.
本实施例中,支持分段的流传输业务主要指基于HTTP STREAM协议的视频流传输业务,例如,现有常见的视频浏览的网站所提供的视频在线观看就属于支持分段的流传输业务,当UE要访问某个视频时,会向提供该视频的服务器发送流协议协商消息,该流协议协商消息中携带DPI信息,DPI信息用于标识UE所访问业务的业务类型,因此RAN设备可以预先保存网络中所有支持分段的流传输业务的DPI信息。In this embodiment, the stream transmission service that supports segmentation mainly refers to the video stream transmission service based on the HTTP STREAM protocol. For example, the online viewing of videos provided by existing common video browsing websites belongs to the stream transmission service that supports segmentation. When the UE wants to access a video, it will send a stream protocol negotiation message to the server that provides the video. The stream protocol negotiation message carries DPI information. The DPI information is used to identify the service type of the service accessed by the UE. Therefore, the RAN device can pre- Save the DPI information of all streaming services that support segmentation in the network.
步骤302:按照预设的时间周期更新保存的支持分段的流传输业务的DPI信息。Step 302: Updating the stored DPI information of the segmented streaming service according to a preset time period.
由于无线网络中支持分段的流传输业务是不断变化的,因此可以按照预设的时间周期更新保存的支持分段的流传输业务的DPI信息,例如,每周更新一次,或者每两周更新一次,以确保RAN设备可以根据DPI信息准确识别UE所访问业务是否为支持分段的流传输业务。Since the segmented streaming service in the wireless network is constantly changing, the saved DPI information of the segmented streaming service may be updated according to a preset time period, for example, once a week or every two weeks Once, to ensure that the RAN device can accurately identify whether the service accessed by the UE is a streaming service that supports segmentation according to the DPI information.
步骤303:从UE与所访问业务所在服务器之间传输的流协议协商消息中获取UE所访问业务的DPI信息。Step 303: Obtain the DPI information of the service accessed by the UE from the stream protocol negotiation message transmitted between the UE and the server where the service is accessed.
当UE通过访问视频网站想要对其中浏览的某个在线视频进行观看时,UE会向该视频所在的服务器发送流协议协商消息,该流协议协商消息中携带了视频的DPI信息,当该流协议协商消息通过RAN设备传输时,RAN设备可以从中获取到该视频的DPI信息。When the UE wants to watch an online video browsed by visiting a video website, the UE will send a stream protocol negotiation message to the server where the video is located. The stream protocol negotiation message carries the DPI information of the video. When the stream When the protocol negotiation message is transmitted through the RAN device, the RAN device can obtain the DPI information of the video from it.
步骤304:判断UE所访问业务的DPI信息与预先保存的DPI信息是否匹配,若匹配,则执行步骤305;否则,执行步骤309。Step 304: Judging whether the DPI information of the service accessed by the UE matches the pre-saved DPI information, and if they match, execute step 305; otherwise, execute step 309.
步骤305:确定UE访问的业务为支持分段的流传输业务。Step 305: Determine that the service accessed by the UE is a segmented stream transmission service.
RAN设备将获取到的DPI信息与预先保存的DPI信息进行匹配,当获取到的DPI信息与预先保存的URL信息中的一个一致时,则说明UE访问的业务为支持分段的流传输业务。The RAN device matches the obtained DPI information with the pre-stored DPI information. When the obtained DPI information is consistent with one of the pre-stored URL information, it means that the service accessed by the UE is a segmented streaming service.
步骤306:判断UE处于DCH状态或者HSPA状态时流传输业务的变化是否满足预先设置的时间判别条件,若满足,则执行步骤307;否则,执行步骤308。Step 306: Judging whether the change of the streaming service when the UE is in the DCH state or the HSPA state satisfies the preset time judging condition, if so, execute step 307; otherwise, execute step 308.
结合图1A可知,UE在访问支持分段的流传输业务时可能进行自动状态迁移,该自动状态迁移包括从DCH状态迁移到IDLE状态,或者从HSPA状态迁移到IDLE状态,因此本实施例中判别UE处于DCH状态或者HSPA状态时流传输业务的变化是否满足预先设置的时间判别条件。It can be seen from FIG. 1A that UE may perform automatic state transition when accessing a streaming service that supports segmentation. The automatic state transition includes transition from DCH state to IDLE state, or transition from HSPA state to IDLE state. Therefore, in this embodiment, it is determined that When the UE is in the DCH state or the HSPA state, whether the change of the streaming service satisfies the preset time judgment condition.
其中,时间判别条件可以根据支持分段的流传输业务的特点进行设置,例如,设置时间判别条件为5分钟,即判断UE处于DCH状态或者HSPA状态时,在5分钟内如果没有数据传输,则说明UE处于DCH状态或者HSPA状态时流传输业务的变化满足预先设置的时间判别条件。Among them, the time discrimination condition can be set according to the characteristics of the stream transmission service that supports segments. For example, the time discrimination condition is set to 5 minutes, that is, when it is judged that the UE is in the DCH state or the HSPA state, if there is no data transmission within 5 minutes, then It shows that when the UE is in the DCH state or the HSPA state, the change of the streaming service satisfies the preset time discrimination condition.
步骤307:确定UE从DCH状态或者HSPA状态移到空闲状态,结束当前流程。Step 307: Determine that the UE moves from the DCH state or the HSPA state to the idle state, and end the current procedure.
流传输业务的变化满足预先设置的时间判别条件,则确定UE从DCH状态或者HSPA状态移到空闲状态。If the change of the stream transmission service satisfies the preset time discrimination condition, it is determined that the UE moves from the DCH state or the HSPA state to the idle state.
步骤308:确定UE保持在DCH状态或者HSPA状态,结束当前流程。Step 308: Determine that the UE remains in the DCH state or the HSPA state, and end the current procedure.
流传输业务的变化不满足预先设置的时间判别条件,则确定UE保持在DCH状态或者HSPA状态。If the change of the stream transmission service does not meet the preset time discrimination condition, it is determined that the UE remains in the DCH state or the HSPA state.
步骤309:采用现有状态迁移判别条件对UE的状态迁移进行确定,结束当前流程。Step 309: Determine the state transition of the UE by using the existing state transition judging conditions, and end the current process.
UE所访问业务的URL信息与预先保存的URL信息不匹配,说明UE访问的业务不是支持分段的流传输业务,因此RAN设备可以采用现有状态迁移判别条件对UE的状态迁移进行判别。If the URL information of the service accessed by the UE does not match the pre-saved URL information, it means that the service accessed by the UE is not a streaming service that supports segmentation. Therefore, the RAN device can use the existing state transition judgment conditions to judge the state transition of the UE.
由上述实施例可见,该实施例通过DPI信息识别UE访问的业务为支持分段的流传输业务,然后采用为支持分段的流传输业务专门设置的时间判别条件对UE的状态迁移进行判别,而不是采用现有状态迁移条件进行判别,因此可以检测到UE在访问支持分段的流传输业务时的实际迁移状态,避免了对网络监控资源的浪费。It can be seen from the above-mentioned embodiment that in this embodiment, the service accessed by the UE is identified as a stream transmission service that supports segmentation through DPI information, and then the state transition of the UE is judged by using the time discrimination condition specially set for the stream transmission service that supports segmentation. Instead of using the existing state transition conditions for discrimination, it is possible to detect the actual transition state of the UE when accessing the segmented stream transmission service, avoiding the waste of network monitoring resources.
