Description

Method and device for establishing bearing and readable storage medium

The present application is a divisional application, the original application having application number 201910117763.7, the original application date being 2019, 2 and 15, the entire content of the original application being incorporated by reference in the present application.

Technical Field

Background

With the popularization of terminals, the types of applications (applications) installed in terminals (such as mobile phones) are increasing, and various services are provided for terminal users. In order to enable the user to obtain better service experience, a dedicated bearer is sometimes established to carry service data between the terminal application and the server.

In the related art, a Policy and Charging Rules Function (PCRF) notifies a Public Data Network (PDN) gateway (PGW) of information required for creating a dedicated bearer for an application of an end user, where the information mainly includes (quality of service, QoS) information and flow information. When a user starts to transmit data between a User Equipment (UE) application and a server, a PGW detects an Internet Protocol (IP) packet and matches the packet filter in flow information. After matching a certain packet filter, the PGW initiates a dedicated bearer establishment procedure according to the dedicated bearer information corresponding to the packet filter, from the PGW to a Serving Gateway (SGW) to an evolved node B (eNB), and finally to the UE to establish a dedicated bearer. The IP flow will then use the dedicated bearer transport to guarantee QoS.

Detailed Description

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

With the popularization of terminals, the types of applications (applications) installed in terminals (e.g., mobile phones) are increasing, and as shown in fig. 1, these applications communicate with corresponding Internet (Internet) servers through a mobile network, so as to provide various services (services) to terminal users.

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

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

The 3GPP protocol defines a proprietary bearer for the corresponding QoS information and flow information. The QoS information includes transmission quality that needs to be guaranteed end to end by this dedicated bearer, including but not limited to delay (packet delay), packet error rate (packet error rate), bandwidth (bitrate), and the like. The flow information is used to define which applications' communication data between the UE and the server are transmitted using the dedicated bearer. The stream information includes at least one packet filter (packet filter). The main information for each packet filter includes the IP address of the Internet server, the subnet mask, the protocol number (e.g., TCP, UDP), the port range, and the UE-side port range.

After one or more special bearers are established, when UE or PDN GW transmits data to the other side, the information of the IP message head is matched with the information of each packet filter of all special bearers, if a certain packet filter is matched, the IP message is put on the corresponding special bearer for transmission. If no packet filter is matched, the IP message is put on the default bearer for transmission. Since the dedicated bearer defines QoS, service data is transmitted in the dedicated bearer to obtain better service experience than in the default bearer. To expand revenue, operators wish to sell network acceleration packages to end users. For the user who purchases the acceleration package, when the specific application/service is used, a special bearer is created to transmit data, and better service experience is provided.

In the related art, the message flows and information elements defined by 3GPP protocols 23.203, 23.041, 29.212 and 29.274 are basically adopted. In a network deployed with dynamic Policy Control and Charging (PCC), as shown in fig. 2, after an end user purchases a network acceleration packet, the PCRF notifies the PGW of information needed to create a dedicated bearer for an application of the end user. These information mainly include QoS information and flow information. After a user starts to transmit data between the UE application and the server, the PGW detects an IP message and matches the IP message with a packet filter. After matching a certain packet filter, the PGW initiates a dedicated bearer establishment procedure according to the dedicated bearer information corresponding to the packet filter, and establishes a dedicated bearer from the PGW to the SGW to the eNB and finally to the UE. The IP flow will then use the dedicated bearer transport to guarantee QoS.

That is, in the related art, the network side specifies QoS information and flow information of the dedicated bearer, triggers creation of the dedicated bearer, and the UE passively participates in creation of the dedicated bearer.

However, the UE may use a limited number of proprietary bearers and packet filters (e.g., the UE may create up to 10 proprietary bearers and up to 16 packet filters per proprietary bearer). There are thousands of UE applications, each with the IP addresses of many servers. Thus, the operator cannot provide proprietary bearers for all applications and risks packet filter starvation even when only one application is provided. In this case, the operator sells network acceleration packets to the end user, only part of the hot applications can be selected to use the proprietary bearer, and the number of server IP addresses corresponding to these applications does not exceed the number of packet filters. However, this external condition is not necessarily true. Even if the method is established, the application range capable of accelerating is limited, and the sales volume of the network acceleration package is seriously influenced under the actual conditions that the number of UE applications is large and the terminal user is personalized.

Under the condition that the number of the special bearers and the number of the packet filters are limited, in order to face the reality that the UE applies thousands of applications and the terminal user is personalized, how to use the special bearers to realize network acceleration for various applications of the UE becomes a problem to be solved urgently. In view of this, the embodiments of the present application provide a method for establishing a bearer, where the UE directly or indirectly provides information required for creating a dedicated bearer, so that the UE creates the dedicated bearer on a network side. The information required by the establishment of the special bearer does not need to be determined in advance, the problem of insufficient packet filters is effectively solved, and therefore under the condition that the special bearer and the number of the packet filters are limited, the network acceleration can be realized for various applications of the UE by using the special bearer in the face of the reality that thousands of UE applications and terminal users are personalized.

Next, before describing the method provided by the embodiment of the present application, a description will be given of an implementation scenario of the method provided by the embodiment of the present application. Optionally, the method provided in the embodiment of the present application includes, but is not limited to, being applied to the following two scenarios:

scene one: and the UE calls the network capability, informs the acceleration application type and the IP layer information of the server end and triggers the establishment of the special bearer.

As shown in fig. 3, the system shown in the scenario one includes devices such as a UE, an eNodeB, an SGW, a PGW, a UE server, an SCEF, a PCRF, and an Internet server.

Wherein the UE comprises a kernel system and an installed application. The kernel system provides an interface supporting the end user to select the application needing acceleration, i.e. to determine the target application needing acceleration. When an application communicates with an application server on the Internet, the kernel system needs to detect the type of application (including but not limited to video, games, web pages, instant messaging) and the IP address of the application server. The kernel system participates in the special bearer creation, completes the matching of the IP message of the application and the packet filter, and transmits the IP message of the application by using the corresponding bearer.

The eNodeB and the SGW are 3GPP standard network elements and participate in establishing and using the special bearer.

The PGW is a 3GPP standard network element, and provides functions of session management and bearer control, data forwarding, IP address allocation, non-3 GPP user access, and the like for a user.

The SCEF is a network element opened for the network capability defined by 3GPP, receives the application information transmitted by the UE server, and forwards the application information to the PCRF.

The PCRF is a network element defined by the 3GPP and used for executing the PCC policy issuing. In scenario one, application information forwarded by the SCEF is received, QoS information is generated according to the type of the acceleration 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 a UE manufacturer and serves as an Internet server for the UE kernel system. In a scenario one that the UE invokes the network capability, the UE kernel system notifies the UE cloud of the acceleration application type and the server IP layer information. The UE cloud passes these application information to the SCEF.

Scene two: the UE directly interacts with the network to inform the acceleration application server end of IP layer information and trigger the establishment of the special bearer.

As shown in fig. 4, the system shown in the scenario two includes a UE, an eNodeB, an SGW, a PGW, a PCRF, and an Internet server.

And the PCRF informs the PGW of QoS information of various applications in a second scene.

The PGW detects application server IP layer information of the UE in scenario two, 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 the PGW in scenario two are different from those in scenario one, the functions of other devices in scenario two may refer to the description in scenario one, and are not described herein again.

In addition, the foregoing scenario and the method provided in the embodiment of the present application mainly describe an implementation process in an LTE mobile network, and related network elements include an SGW, a PGW, an eNodeB, and a UE, and the network elements have defined subsequent form and function evolution in a 3GPP protocol. For example, the SGW may subsequently evolve into two network elements, SGW-C and SGW-U. The method provided by the embodiment of the application is also applicable to the network element equipment after subsequent evolution. The method provided by the embodiment of the application is not only suitable for applying network acceleration in the 4G network, but also suitable for a network acceleration solution selected by a user in a mobile network (such as 4.5G and 5G) in subsequent evolution.

Based on the first scenario, the present application provides a method for establishing a bearer, as shown in fig. 5, the method provided by the present application is cooperatively completed by each device in the first scenario, and includes the following steps.

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

The UE is a terminal which purchases a network acceleration packet, and the UE sets which applications need network acceleration by using a target application setting interface provided by a kernel system, so that the target applications are determined by setting information on the setting interface. Because the user can set the target application needing network acceleration through the setting interface, the personalized requirements of the user can be further met.

It should be understood that this step 501 is performed without setting a target application or setting a new target application, and is an optional step in the method for establishing a bearer provided in the embodiment of the present application. If the target application has already been set and a new target application does not need to be set, step 502 may be performed directly without performing step 501.

In step 502, when the target application is running, the UE acquires application information of the target application, the application information including an application type and application server IP layer information.

When a user runs a target Application needing network acceleration on UE, a kernel system of the UE judges the Application type (videos, games, web pages, instant messaging and the like) of the target Application according to an Application identifier (Application Id) of the target Application. In addition, the kernel system of the UE also acquires IP layer information such as an application server IP address, a port number, a protocol type and the like of the target application. And then, 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 kernel system of the UE sends the application information of the target application, i.e. the application type and the application server IP layer information (including the server IP address, the port number, the protocol type, etc.), to the network side, so as to trigger the network side device to establish the dedicated bearer of the target application based on the application server IP layer information of the target application. E.g., notified to the UE server, step 504 is performed.

Optionally, the notification protocol used when the UE notifies the UE server of the application information of the target application may be HTTP or other mature protocol, 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, the application information may be forwarded using an HTTP Restful interface according to the existing protocol definition of 3 GPP. The HTTP Restful interface can provide services for Web, iOS and Android through a set of uniform interfaces.

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

For this step, when the SCEF forwards the application information of the target application to the PCRF, the HTTP Restful interface may be used according to the protocol definition already existing in 3 GPP.

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

The PCRF analyzes the application information of the target application, searches QoS parameters (such as time delay, packet error rate, bandwidth and the like) corresponding to various pre-configured application types according to the application types after obtaining the application types, and generates QoS information required by creating the special bearer according to the QoS parameters corresponding to the various application types. In addition, the PCRF parses the application information of the target application to obtain the IP layer information of the application server of the target application, and then generates the flow information required for creating the dedicated bearer according to the IP layer information such as the IP address, the port number, the protocol type, and the like of the application server.

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

For the step, the PCRF may notify the PGW of the QoS information, the flow information, and the like through the 3GPP Gx interface protocol specification, and notify the PGW to create the dedicated bearer. Wherein, the Gx interface is an 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 remove PCC rules of the PCRF to or from the PCEF, and to communicate related events from the PCEF to the PCRF. In this embodiment of the present application, the PCRF may notify the PGW of the QoS information, the flow information, and the like through the 3GPP Gx interface protocol specification, so that the PGW creates a dedicated bearer based on the QoS information and the 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 proprietary bearer.

After the PGW interacts with the SGW, eNodeB, and UE and a dedicated bearer is created, communication data between the target application and the server can be transmitted using the dedicated bearer, and since the dedicated bearer defines QoS, better service experience can be obtained when service data is transmitted on the dedicated bearer.

It should be noted that, taking the UE running a target application that needs network acceleration as an example, if the user runs an application that is not set to need network acceleration on the UE, the kernel system may sense that the application does not need network acceleration, so that the dedicated bearer establishment step is not needed. In addition, in order to improve the performance, the kernel system can directly put the message of the non-acceleration application on the default bearer for transmission.

Compared with the related technology, the method provided by the embodiment of the application has the advantages that the information (mainly a packet filter) required by the special bearer is created and is notified to the PCRF through the network capability open network element when the target application needing acceleration runs, and the setting on the PCRF in advance is not needed.

For convenience of understanding, referring to fig. 6, taking the UE with the application 1, the application 2, and the application 3 installed thereon, and respectively corresponding to the application 1 server, the application 2 server, and the application 3 server as an example, through the above process of establishing the dedicated bearer, the dedicated bearer 1 is established for the application 1, the dedicated bearer 2 is established for the application 2, and the dedicated bearer 3 is established for the application 3. Taking the establishment of the dedicated bearer 1 of the application 1 as an example, the UE notifies the application information of the application 1 to the UE server, the UE server notifies the SCEF of the application information, and the SCEF notifies the PCRF of the application information of the application 1. And the PCRF acquires the special bearing information according to the application information, namely flow information and QoS information required by the establishment of the special bearing. Further, the PCRF notifies the dedicated bearer information to the PGW, and the PGW interacts with the SGW, the eNodeB, and the UE to create the dedicated bearer 1, and then the dedicated bearer 1 can be used to transmit the data of the application 1.

According to the method provided by the embodiment of the application, when the target application is operated, the IP layer of the application server of the target application is sent to the network side, so that the network side equipment is triggered to establish the special bearer of the target application, information required for establishing the special bearer does not need to be determined in advance, the problem of insufficient packet filters is effectively solved, and under the condition that the special bearer and the number of the packet filters are limited, the reality that thousands of UE applications and terminal users are personalized can be faced, and the special bearer is used for realizing network acceleration for various applications of the UE.

Based on the second scenario, the embodiment of the present application provides a method for establishing a bearer, as shown in fig. 7, the method provided by the embodiment of the present application is completed by cooperation of each device in the second scenario, and includes the following steps.

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

It should be understood that this step 701 is performed without setting a target application or setting a new target application, and is an optional step in the method for establishing a bearer provided in this embodiment of the present application. If the target application is already set and a new target application is not required to be set, step 702 may be directly performed without performing step 701.

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

The PCRF can inform the PGW to create a general special bearing through a Gx interface message, and a cell carried by the message is defined by extension on the basis of a protocol. Further, the message application notifies various types of applications of corresponding QoS parameters and server-side IP address values of the packet filter, wherein 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 s or all F s.

The function of the general dedicated bearer is that when an IP packet (IP layer information) sent to a server by a target application requiring network acceleration cannot match any dedicated bearer packet filter, a UE kernel system transmits the IP packet of the target application using the general dedicated bearer, so that a PGW performs SA detection, thereby triggering creation of a dedicated bearer for transmitting data of the target application.

In step 703, after receiving the message for creating the generic dedicated bearer, the PGW interacts with the SGW, eNodeB, and UE to create the generic dedicated bearer.

After receiving the message for creating the generic dedicated bearer, i.e., receiving the notification for creating the generic dedicated bearer, the PGW creates the generic dedicated bearer based on the QoS parameter and the server-side IP address value of the packet filter. For example, a generic proprietary bearer may be created by interacting with the SGW, eNodeB, UE according to standard procedures defined by 3 GPP. The QoS information corresponding to the universal special load bearing uses the QoS information of the webpage type application, and the server-side IP address of the packet filter in the flow information uses a special value received at a Gx interface.

In step 704, when the target application is running, the UE obtains the IP packet of the target application, and if the IP packet of the target application does not match any packet filter of the dedicated bearer, transmits the IP packet of the target application using the general dedicated bearer.

When a user runs a target application requiring network acceleration on UE, the kernel system matches the information of the IP message header sent to the application server with the information of each packet filter of all proprietary bearers. Since only a generic, proprietary bearer exists at this time, and the server-side IP address in its packet filter is a special value that is not used by the current network, it cannot be matched to any packet filter.

Then, unlike the related art, the kernel system of the UE does not put the data of the application on the default bearer for transmission, but puts the data of the application on a generic dedicated bearer for transmission.

It should be understood that, the UE obtains the IP packet of the target application, and transmits the IP packet of the target application by using the generic dedicated bearer in the case that the IP packet of the target application does not match any packet filter of the dedicated bearer, so as to send the application server IP layer information of the target application to the network side by using the IP packet.

In step 705, the PGW receives an IP packet of the target application transmitted on the generic dedicated bearer, detects an application type of the target application according to the IP packet, determines QoS information required to create the dedicated bearer based on the application type of the target application, obtains application server IP layer information of the target application, and generates flow information required to create the dedicated bearer according to the application server IP layer information.

When the IP packet data of the target application reaches the PGW, the PGW may detect the application type (e.g., video, game, web page, instant messaging, etc.) of the target application through the SA technology, search QoS parameters (e.g., delay, packet error rate, bandwidth) corresponding to various pre-configured application types, and search QoS parameters corresponding to the target application from the QoS parameters corresponding to various applications based on the application type of the target application to obtain QoS information required to create a dedicated bearer, that is, to generate QoS information required to create the dedicated bearer.

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

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

Compared with the related art, the method provided by the embodiment of the application has the advantages that the information (mainly packet filters) required by the establishment of the special bearer is notified to the PCRF by the UE through the network capability open network element when the target application needing acceleration runs, and the method does not need to be set on the PCRF in advance. When the IP message sent to the server by the target application needing acceleration cannot match any special bearer packet filter, the UE kernel system transmits the IP message of the target application by using a general special bearer, so that the PGW performs SA detection, and triggers the creation of the special bearer for transmitting the data of the target application.

For convenience of understanding, referring to fig. 8, taking an example that an application 1 and an application 2 are installed on the UE and an application 1 server and an application 2 server are installed on the internet side, after the default bearer is established, the PCRF notifies the PGW of a special meaning value set by the QoS parameter of each application and the server IP address in the flow information, and notifies the PGW to establish a general dedicated bearer. And when the IP message sent to the server by the target application cannot be matched with any special bearer packet filter, the UE kernel system transmits the IP message of the target application by using the universal special bearer. After the IP message is transmitted to the PGW, the PGW detects the IP message on the universal special bearer by using the SA technology, senses the application type, maps out QoS information, generates flow information according to the IP message and triggers the establishment process of the special bearer. Taking the example of establishing the dedicated bearer 1 for the application 1 as an example, the dedicated bearer 1 is created, and then the data of the application 1 can be transmitted by using the dedicated bearer 1.
