detailed description

The terminology used in the implementation mode of this application is only used to explain the specific embodiments of this application, and is not intended to limit this application.

With the popularization of terminals, there are more and more types of applications (Application) installed on terminals (such as mobile phones). As shown in Figure 1, these applications and corresponding Internet servers communicate through mobile networks to provide terminal users with A variety of services (service).

The main 4G network elements responsible for the communication data transmission between the UE and the Internet server include eNB, SGW and PGW. After the UE is connected to the 4G network, a default bearer will be established end-to-end between the UE, eNodeB, SGW, and PGW.

In order to better guarantee the QoS of various applications on the UE, when the UE uses various applications, the 4G network can create a dedicated bearer to transmit communication data between the UE application and the server.

The 3GPP protocol defines a dedicated bearer with corresponding QoS information and flow information. Among them, the QoS information includes the transmission quality that the dedicated bearer needs to ensure end-to-end, including but not limited to packet delay, packet error loss rate, bandwidth (bitrate), and so on. The flow information is used to define which application communication data between the UE and the server uses this dedicated bearer to transmit. The flow information includes at least one packet filter. The main information of each packet filter includes the IP address of the Internet server, subnet mask, protocol number (such as TCP, UDP), port range, and UE side port range.

After one or more dedicated bearers are established, when the UE or PDN GW transmits data to the other party, the information in the IP packet header is matched with the information of each packet filter of all dedicated bearers. If a certain packet filter is matched The IP packet is put on the corresponding dedicated bearer for transmission. If no packet filter is matched, the IP packet is put on the default bearer for transmission. Since the dedicated bearer defines QoS, compared to the default bearer, service data transmission in the dedicated bearer will have a better service experience. In order to expand revenue, operators hope to sell network acceleration packages to end users. For users who have purchased an acceleration package, when using specific applications/services, create a dedicated bearer to transmit data to provide a better service experience.

In related technologies, message flows and information elements defined in 3GPP protocols 23.203, 23.041, 29.212, and 29.274 are basically used. In a network where dynamic policy control and charging (PCC) is deployed, as shown in Figure 2, after the end user has purchased the network acceleration package, the PCRF notifies the PGW to create a specific application for this end user Carry the required information. This information mainly includes QoS information and flow information. When the user starts to transmit data between the UE application and the server, the PGW will detect the IP packet and match the packet filter. When a certain packet filter is matched, the PGW will initiate a dedicated bearer establishment process according to the dedicated bearer information corresponding to the packet filter, from the PGW to the SGW to the eNB, and finally to the UE to establish a dedicated bearer. After that, this IP flow will use this dedicated bearer to transmit to ensure QoS.

In other words, the related technology is that the network side specifies the QoS information and flow information of the dedicated bearer to trigger the creation of the dedicated bearer, and the UE passively participates in the creation of the dedicated bearer.

However, the number of dedicated bearers and packet filters that the UE can use is limited (for example, the UE can create up to 10 dedicated bearers, and each dedicated bearer can have up to 16 packet filters). There are thousands of UE applications, and each application has many server IP addresses. Therefore, operators cannot provide dedicated bearers for all applications, and even face the risk of insufficient packet filters when providing dedicated bearers for only one application. In this case, when operators sell network acceleration packages to end users, they can only select some popular applications to use proprietary bearers, and the number of server IP addresses corresponding to these applications does not exceed the number of packet filters. However, this external condition does not necessarily hold. Even if it is established, it will limit the scope of applications that can be accelerated. In the reality of a large number of UE applications and personalized end users, it will seriously affect the sales of network acceleration packages.

With the limited number of dedicated bearers and packet filters, facing the reality of thousands of UE applications and personalized end users, how to use dedicated bearers to achieve network acceleration for various UE applications has become an urgent solution The problem. In this regard, the embodiments of the present application provide a method for establishing a bearer. In this method, the UE directly or indirectly provides information required for creating a dedicated bearer for the network side to create the dedicated bearer. The information required to create a dedicated bearer does not need to be determined in advance, which effectively solves the problem of insufficient packet filters, so that when the number of dedicated bearers and packet filters is limited, thousands and thousands of UE applications can be faced. The reality of personalization of end users, using dedicated bearers to achieve network acceleration for various applications of the UE.

Next, before introducing the method provided by the embodiment of the present application, first introduce the implementation scenario of the method provided by the embodiment of the present application. Optionally, the methods provided in the embodiments of this application include but are not limited to being applied to the following two scenarios:

Scenario 1: The UE invokes the network capabilities, notifies the acceleration application type and server-side IP layer information, and triggers the creation of a dedicated bearer.

As shown in Figure 3, the system shown in this scenario one includes equipment such as UE, eNodeB, SGW, PGW, UE server, SCEF, PCRF, and Internet server.

Among them, UE includes the kernel system and installed applications. The kernel system provides an interface to support end users to select applications that need to be accelerated, that is, to determine target applications that need to be accelerated. When an application communicates with an application server on the Internet, the kernel system needs to detect the type of application (the application type includes but not limited to video, game, web page, instant messaging) and the IP address of the application server. The kernel system participates in the creation of a proprietary bearer, completes the matching of the applied IP message and packet filter, and uses the corresponding bearer to transmit the application's IP message.

eNodeB and SGW are 3GPP standard network elements that participate in the establishment and use of dedicated bearers.

PGW is a 3GPP standard network element that provides functions such as user session management and bearer control, data forwarding, IP address allocation, and non-3GPP user access.

SCEF is a network element defined by 3GPP for network capability opening, which receives application information from the UE server and forwards it to PCRF.

PCRF is a network element defined by 3GPP that executes the PCC policy issued. In scenario 1, the application information forwarded by SCEF is received, QoS information is generated according to the type of accelerated application, flow information is generated according to the server-side IP layer information, and the PGW is notified to create a dedicated bearer.

The UE server is provided by the UE manufacturer and serves as an Internet server for the UE core system. In the first scenario where the UE invokes the network capability, the UE core system notifies the UE cloud of the accelerated application type and server-side IP layer information. The UE cloud transfers these application information to SCEF.

Scenario 2: The UE directly interacts with the network, notifies the accelerated application server of IP layer information, and triggers the creation of a dedicated bearer.

As shown in Figure 4, the system shown in the second scenario includes UE, eNodeB, SGW, PGW, PCRF, and Internet server.

Among them, the PCRF notifies the PGW of the QoS information of various applications in the second scenario.

The PGW detects the IP layer information of the UE's application server in the second scenario, and generates flow information accordingly. In addition, the PGW also detects the application type of the UE, and creates a dedicated bearer according to the QoS information corresponding to the application type notified by the PCRF.

Except that the functions of the PCRF and PGW in the scenario 2 are different from those in the scenario 1, the functions of other devices in the scenario 2 can refer to the introduction in the foregoing scenario 1, which will not be repeated here.

In addition, the above scenarios and the methods provided in the embodiments of this application mainly describe the implementation process in the LTE mobile network. The network elements involved include SGW, PGW, eNodeB, and UE. These network elements have defined subsequent forms and functions in the 3GPP protocol. Evolution. For example, the SGW may subsequently evolve into two network elements, SGW-C and SGW-U. For the subsequent evolved network element equipment, the method provided in the embodiment of this application is also applicable. Moreover, the method provided by the embodiments of the present application is not only suitable for application network acceleration in 4G networks, but also suitable for user-selected network acceleration solutions in subsequent evolved mobile networks (for example, 4.5G and 5G).

Based on the above scenario one, an embodiment of the present application provides a method for establishing a bearer. As shown in FIG. 5, the method provided in the embodiment of the present application is completed by various devices in scenario one, and includes the following steps.

In step 501, the UE displays a target application setting interface, and determines the target application through the setting interface.

Among them, the UE is a terminal that has purchased a network acceleration package. The target application setting interface provided by the kernel system is used on the UE to set which applications require network acceleration, and the target application is determined through the setting information on the setting interface. Since the user can set the target application that requires network acceleration through the setting interface, it can further meet the user's personalized needs.

It should be understood that this step 501 is executed when the target application is not set or a new target application is set, and is an optional step in the bearer establishment method provided in the embodiment of the present application. If the target application has been set and there is no need to set a new target application, step 501 may not be executed, and step 502 may be executed directly.

In step 502, when the target application is running, the UE obtains application information of the target application. The application information includes application type and application server IP layer information.

When a user runs a target application that requires network acceleration on the UE, the kernel system of the UE determines the application type (video, game, webpage, instant messaging, etc.) of the target application according to the application ID of the target application. In addition, the UE's core system also obtains IP layer information such as the application server IP address, port number, and protocol type of the target application. After that, the UE obtains the application information of the target application according to the application type of the target application and the IP layer information of the application server.

In step 503, the UE notifies the UE server of the application information of the target application.

The core system of the UE sends the application information of the target application, namely the application type and application server IP layer information (including server IP address, port number, protocol type, etc.) to the network side to trigger the network side device based on the application server IP of the target application The layer information establishes the dedicated bearer of the target application. For example, the UE server is notified, and step 504 is executed.

Optionally, the notification protocol used by the UE to notify the UE server of the application information of the target application may be HTTP or other mature protocols, which is not limited in this application.

In step 504, the UE server forwards the application information of the target application to the SCEF.

For this step, when the UE server forwards the application information of the target application to the SCEF, it can be forwarded using the HTTP Restful interface according to the existing 3GPP protocol definition. Among them, the HTTP Restful interface can provide services for the Web, iOS and Android through a unified interface.

In step 505, the SCEF forwards the application information of the target application to the PCRF.

For this step, when SCEF forwards the application information of the target application to PCRF, it can use the HTTP Restful interface according to the existing 3GPP protocol definition.

In step 506, PCRF parses the application information of the target application to obtain the application type and application server IP layer information, and generates the flow information required to create a dedicated bearer according to the application server IP layer information of the target application, and generates it according to the application type of the target application QoS information required to create a dedicated bearer.

PCRF analyzes the application information of the target application and obtains the application type, and then searches the pre-configured QoS parameters (such as delay, packet error rate, bandwidth, etc.) corresponding to various application types according to the application type, and according to the QoS parameters corresponding to various application types Generate the QoS information required to create a dedicated bearer. In addition, PCRF parses the application information of the target application, and obtains the application server IP layer information of the target application, and generates the flow information required to create a dedicated bearer according to the IP layer information such as the application server IP address, port number, and protocol type.

In step 507, the PCRF notifies the QoS information and flow information to the PGW, and notifies the PGW to create a dedicated bearer.

For this step, the PCRF can notify the PGW of QoS information and flow information through the 3GPP Gx interface protocol specification, and notify the PGW to create a dedicated bearer. Among them, the Gx interface is the interface between the PCEF device and the PCRF device. The Gx interface is located between the PCEF functional entity and the PCRF functional entity, and is used for charging control and policy control. The Gx interface is used to provide or delete the PCC rules of the PCRF to the PCEF, and to transmit related events from the PCEF to the PCRF. In the embodiment of this application, the PCRF can notify the PGW of QoS information and flow information through the 3GPP Gx interface protocol specification, so that the PGW creates a dedicated bearer based on the QoS information and flow information. For example, continue to perform step 508 as follows.

In step 508, the PGW interacts with the SGW, eNodeB, and UE to create a dedicated bearer.

After the PGW interacts with the SGW, eNodeB, and UE to create a dedicated bearer, the communication data between the target application and the server can be transmitted using the dedicated bearer. Since the dedicated bearer defines QoS, the service data is Transmission on the bearer can obtain a better service experience.

It should be noted that the above only takes the target application running on the UE that requires network acceleration as an example. If the user runs an application that does not require network acceleration on the UE, the kernel system can perceive that the application does not require network acceleration. , So there is no need to perform the above-mentioned dedicated bearer establishment steps. In addition, in order to improve performance, the kernel system can directly transmit this non-accelerated application packet on the default bearer.

Compared with related technologies, the method provided in the embodiments of this application provides information (mainly packet filters) required to create a dedicated bearer, which is notified to the PCRF by the UE through the network capability opening network element when the target application needs to be accelerated. , No need to set on PCRF in advance.

For ease of understanding, referring to Figure 6, taking the application 1, application 2, and application 3 installed on the UE, corresponding to the application 1 server, application 2 server, and application 3 server as an example, through the above process of establishing a dedicated bearer, the application is targeted at application 1. Establish dedicated bearer 1, dedicated bearer 2 for application 2, and dedicated bearer 3 for application 3. Taking the establishment of the dedicated bearer 1 of application 1 as an example, the UE notifies the UE server of the application information of application 1, and the UE server notifies the application information to the SCEF, and then the SCEF notifies the PCRF of the application information of application 1. The PCRF obtains the proprietary bearer information according to the application information, that is, the flow information and QoS information required to create the dedicated bearer. Further, the PCRF notifies the PGW of the dedicated bearer information, and the PGW interacts with the SGW, eNodeB, and UE to create a dedicated bearer 1, and then the dedicated bearer 1 can be used to transmit application 1 data.

The method provided in the embodiments of the present application sends the application server IP layer of the target application to the network side when the target application is running, thereby triggering the network side device to establish a dedicated bearer for the target application, so that the creation of a dedicated bearer is required The information does not need to be determined in advance, which effectively solves the problem of insufficient packet filters, so that in the case of a limited number of dedicated bearers and packet filters, it can face the reality of thousands of UE applications and personalized end users. Use dedicated bearers to achieve network acceleration for various UE applications.

Based on the above scenario two, an embodiment of the present application provides a method for establishing a bearer. As shown in FIG. 7, the method provided in the embodiment of the present application is completed by the various devices in the scenario two, including the following steps.

In step 701, the UE displays a target application setting interface, and determines the target application through the setting interface.

It should be understood that this step 701 is executed when the target application is not set or a new target application is set, and is an optional step in the bearer establishment method provided in the embodiment of the present application. If the target application has already been set and there is no need to set a new target application, step 701 may not be executed, and step 702 may be executed directly.

In step 702, after the default bearer is established, the PCRF notifies the PGW to create a general dedicated bearer.

Among them, the PCRF can notify the PGW to create a general dedicated bearer through a Gx interface message, and the information element carried in this message is extended and defined on the basis of the protocol. Further, this message application informs various applications of the corresponding QoS parameters and the server-side IP address value of the packet filter. The server-side IP address in the flow information is set to a special value that is not used by the existing network, such as all 0 or Full F.

The function of the universal dedicated bearer is to use the universal dedicated bearer to transmit the target application when the IP message (IP layer information) sent by the target application that needs network acceleration to the server cannot match any proprietary bearer packet filter. The IP packet is used by the PGW for SA detection, which triggers the creation of a dedicated bearer for the data of the target application.

In step 703, after the PGW receives the message to create a universal dedicated bearer, it interacts with the SGW, eNodeB, and UE to create a universal dedicated bearer.

After the PGW receives the message of creating a general dedicated bearer, that is, it receives the notification of creating a general dedicated bearer, the PGW creates a general dedicated bearer based on the QoS parameters and the server-side IP address value of the packet filter. For example, it can interact with SGW, eNodeB, and UE in accordance with the standard process defined by 3GPP to create a general dedicated bearer. Among them, the QoS information corresponding to the general-purpose proprietary bearer uses the QoS information of the web type application, and the server-side IP address of the packet filter in the flow information uses the special value received on the Gx interface.

In step 704, when the target application is running, the UE obtains the IP packet of the target application. If the IP packet of the target application does not match the packet filter of any dedicated bearer, the general dedicated bearer is used to transmit the IP packet of the target application .

When a user runs a target application that requires network acceleration on the UE, the kernel system matches the information in the header of the IP packet sent to the application server with the information in each packet filter of all proprietary bearers. Since there is only a general-purpose dedicated bearer at this time, and the server-side IP address in its packet filter is a special value that is not used on the live network, it cannot match any packet filter.

After that, unlike related technologies, the core system of the UE does not put the data of this application on the default bearer for transmission, but puts the data of this application on the general dedicated bearer for transmission.

It should be understood that the UE obtains the IP packet of the target application, and in the case that the IP packet of the target application does not match the packet filter of any dedicated bearer, the general dedicated bearer is used to transmit the IP packet of the target application to pass The IP message sends the application server IP layer information of the target application to the network side.

In step 705, the PGW receives the IP packet of the target application transmitted on the general dedicated bearer, detects the application type of the target application according to the IP packet, and determines the QoS information required to create the dedicated bearer based on the application type of the target application , Obtain the application server IP layer information of the target application, and generate the flow information needed to create a dedicated bearer based on the application server IP layer information.

When the IP packet data of the target application arrives at the PGW, the PGW can detect the application type of the target application (such as video, game, web, instant messaging, etc.) through the SA technology, and find the QoS corresponding to the various application types configured in advance Parameters (such as delay, packet error rate, bandwidth), based on the application type of the target application, search for the QoS parameters corresponding to the target application from the QoS parameters corresponding to various applications, and obtain the QoS information required to create a dedicated bearer, that is, generate QoS information required to create a dedicated bearer.

In addition, the PGW obtains the application server IP layer information of the target application based on the IP message of the target application, and generates the flow information required to create a dedicated bearer according to the application server IP layer information (IP address, port number, protocol type, etc.).

In step 706, the PGW interacts with the SGW, eNodeB, and UE to create a dedicated bearer.

Compared with related technologies, the method provided in the embodiments of this application, except for the information required to create a dedicated bearer (mainly packet filters), is notified to the PCRF by the UE through the network capability opening network element when the target application needs to be accelerated. Yes, it does not need to be set on the PCRF in advance, this method also creates a universal dedicated bearer. When the IP packet sent by the target application to the server that needs to be accelerated cannot match any proprietary bearer packet filter, the UE core system uses the general dedicated bearer to transmit the IP packet of the target application for the PGW to do SA detection and trigger the creation of transmission Dedicated bearer of target application data.

For ease of understanding, refer to Figure 8. Taking the application 1 and application 2 installed on the UE, and the application 1 server and application 2 server on the Internet side as an example, PCRF will set the QoS parameters and flow of various applications after the default bearer is established. The value of the special meaning set to the server IP address in the information is notified to the PGW, and the PGW is notified to establish a general dedicated bearer. When the IP packet sent by the target application to the server cannot match any proprietary bearer packet filter, the UE core system uses the general dedicated bearer to transmit the IP packet of the target application. After the IP message is transmitted to the PGW, the PGW uses SA technology to detect the IP message on the general dedicated bearer, senses the application type, maps out QoS information, generates flow information based on the IP message, and triggers the establishment of the dedicated bearer. Take the establishment of dedicated bearer 1 for application 1 as an example, create dedicated bearer 1 and then use the dedicated bearer 1 to transmit data of application 1.
