technical field

The invention relates to the technical field of wireless communication, in particular to a method and equipment for judging terminal state transition.

Background technique

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.

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.

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.

Detailed ways

The following embodiments of the present invention provide a method and equipment for judging terminal state transition.

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.

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:

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.

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.

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:

Step 101: Identify that the service accessed by the UE is a segmented stream transmission service.

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.

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.

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.

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.

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.

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.

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.

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:

Step 201: pre-store URL information of a streaming service that supports segmentation.

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.

Step 202: Update the saved URL information of the stream transmission service supporting segments according to a preset time period.

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.

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.

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.

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.

Step 205: Determine that the service accessed by the UE is a segmented stream transmission service.

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.

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.

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.

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.

Step 207: Determine that the UE moves from the DCH state or the HSPA state to the idle state, and end the current procedure.

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.

Step 208: Determine that the UE remains in the DCH state or the HSPA state, and end the current process.

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.

Step 209: Determine the state transition of the UE by using the existing state transition judgment condition, and end the current process.

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.

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.

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:

Step 301: Pre-save the DPI information of the stream transmission service that supports segmentation.

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.

Step 302: Updating the stored DPI information of the segmented streaming service according to a preset time period.

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.

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.

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.

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.

Step 305: Determine that the service accessed by the UE is a segmented stream transmission service.

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.

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.

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.

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.

Step 307: Determine that the UE moves from the DCH state or the HSPA state to the idle state, and end the current procedure.

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.

Step 308: Determine that the UE remains in the DCH state or the HSPA state, and end the current procedure.

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.

Step 309: Determine the state transition of the UE by using the existing state transition judging conditions, and end the current process.

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.

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.
