Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for processing user data.
Background
In a wireless evolution network, mobile phones are more and more widely used, and various applications occupying high bandwidth, such as videos and online games, are more and more used, and the applications occupy a large amount of bandwidth resources of the network. For access network devices, due to limited access network device resources, when these applications use network resources in large quantities, the access network devices may be congested. For the above situation, in the prior art, a gateway device or a TDF (Traffic Detection Function, data Detection Function entity) on a network side differentiates all downlink data packets according to some conditions, for example, a processing identifier is added to the data packet, and the downlink data packets are classified into different types, so that an access network device can perform differentiation processing on the downlink data packets according to the different types of the downlink data packets. For example, the network side generates the priority of a data packet according to the information such as the type of the user, the application type of the data packet, and the like, so that the data stream can divide the data packet into several types according to different priorities, and after the access network device receives the downlink data packet, differentiation processing is performed according to the priority of the data packet, such as priority processing with high priority, and later processing or even dropping is possible when the priority is low.
The prior art has at least the following problems: the processing identifier in the data flow is generated by each operator according to the customized condition, and how the access network equipment processes the data packets is also customized by each operator. When the user equipment roams, if the user equipment establishes PDN (Packet Data Network) connection or performs Data transmission with a gateway of a Home Public Land Mobile Network (HPLMN) operator through a Virtual Public Land Mobile Network (VPLMN) access Network, a downlink Data stream of the user passes through the gateway device of the HPLMN of the user, and the gateway device of the HPLMN adds a Packet processing identifier defined and generated by the Home operator in the downlink Data stream. In this way, after the downlink data packet arrives at the access network of the roaming-place operator, the roaming-place operator defines that the meaning of the data packet processing identifier may be different from the home location, and when the roaming-place access network processes the data packet from the home-place gateway device, the data packet is processed according to the processing rule of the roaming-place processing identifier according to the processing identifier of the data packet, so that the data packet cannot be processed normally.

When the processing identifier is a priority identifier, the processing mode is to process the downlink data packet according to different priority levels in a grading manner; when the processing identifier is a service type identifier, the processing mode is to process the downlink data packet in a grading way according to different service type grades; and when the processing identifier is the data stream identifier, the processing mode is to process the downlink data packet in a grading way according to different data stream grades.
It should be noted that the embodiment of the present invention may also be used in a scenario where the user equipment is in a roaming state, but a PLMN to which the PGW gateway device belongs is the same as a VPLMN in which the user equipment is located.
In the prior art, after a downlink data packet arrives at an access network of a roaming operator, the roaming operator defines that a generated data packet processing identifier may be different from an attribution, and when the roaming access network processes the downlink data packet from an attribution gateway device, the data packet is processed according to the processing rule of the roaming processing identifier and the processing identifier of the downlink data packet, so that the data packet cannot be processed normally. Compared with the prior art, after receiving a downlink data packet which is sent by a packet data network gateway (PGW) and contains a processing identifier, the access network equipment of the VPLMN in the embodiment of the invention determines that the PGW is a gateway of a Home Public Land Mobile Network (HPLMN) according to indication information, wherein the indication information is used for indicating that the PGW is the gateway of the HPLMN; and the access equipment determines the processing mode of the downlink data packet according to the processing identifier and the gateway with the PGW as the HPLMN. Thus, the access network equipment of the VPLMN determines that the PGW sending the data packet is the gateway of the HPLMN according to the indication information of the downlink data packet, and determines the processing mode of the downlink data packet according to the processing identifier of the HPLMN, so that the access network equipment of the VPLMN can correctly determine the processing mode of the downlink data packet sent by the gateway of the HPLMN and correctly process the downlink data packet.
A further embodiment of the present invention provides a method for processing user data, which is used for an access network device, and taking an attach process of a UE in a roaming network as an example, the access network device configures a corresponding relationship between a processing identifier of an HPLMN and a processing identifier of a VPLMN, where a PGW (PDN Gateway) is a Gateway device of the HPLMN, and an SGW (Serving Gateway) is a Gateway device of the VPLMN, as shown in fig. 3, and the method includes:
201. the user equipment sends an attach request to the mobility management entity.
The user equipment initiates an attachment request to the mobility management entity through the access network equipment. The mobility management entity mainly completes functions of mobility management, session management, encryption and integrity protection of NAS layer signaling, PGW or SGW selection and the like of UE under the Access of E-UTRAN (Evolved Universal Mobile telecommunication System terrestrial Radio Access Network). The MME may save the bearer context information when the UE is in an idle state. When the user equipment is attached to the roaming network, an attachment request is initiated to the mobility management entity through the access network equipment.
202. The mobility management entity sends a create session request to the serving gateway SGW.
The request message includes an address of a PGW or GGSN (Gateway Radio service support Node) Gateway device. The SGW may determine whether the PGW or GGSN gateway address included in the session creation request is located in the home network or the roaming network to which the ue belongs, according to the already configured address information of the PGW or GGSN gateway device belonging to the roaming network. The SGW is mainly responsible for relaying user traffic between the user equipment and the PGW, and serves as an anchor point when switching between access network devices.
Optionally, in order to avoid configuration workload of the SGW, the mobility management entity may also include a gateway location indication in a request message for sending a session creation request to the serving gateway SGW, and after receiving an attach request of the user equipment, the MME may select a corresponding gateway device for the user equipment. The MME can know whether the gateway device of the home PLMN to which the UE is currently attached is the gateway device of the roaming PLMN, so the location handled by the gateway device is included in the gateway location indication, and indicates to the SGW whether the PGW or GGSN gateway is located in the home network or the roaming network.
203. The SGW sends a create session request to the PGW.
The PGW is a gateway (which may be a packet network inside or outside an operator) connected to a PDN network providing services, and is responsible for forwarding and filtering user data streams.
204. The PGW sends a create session response to the SGW.
205. The SGW sends a create session response to the MME.
206. The MME sends an initial context request or an attach accept request to the access network device.
Wherein, the initial context request or the attachment acceptance request carries the home network identifier of the user equipment.
Optionally, the initial context request or the attach accept request carries the location information of the PGW.
207. And the access network equipment sends a radio resource control connection reconfiguration message to the UE.
208. And the access network equipment sends a radio resource control connection reconfiguration completion message to the UE.
209. The access network equipment sends an initial up-down setup response to the MME.
It should be noted that, after the above-mentioned process is executed, the access network device obtains the identifier of the home network of the UE, and the following processing manner may be used in the data transmission process.
210. And the PGW identifies the processing identification of the data packet in the downlink data packet.
The processing identifier of the PGW in the data packet identified by the downlink data packet is a processing identifier defined by a home network operator to which the user equipment belongs.
211. And the PGW sends a downlink data packet to the SGW.
212. And the SGW adds a flag bit for the downlink data packet.
After the downlink data packet reaches the SGW, the SGW adds a flag bit to the downlink data packet according to the position of the PGW that transmits the downlink data packet, indicating the network that transmits the downlink data packet. The type of representation is not limited, for example, "0" indicates that the packet is from the home network.
213. And the SGW sends a downlink data packet to the access network equipment.
214. The access network equipment determines the correct processing mode of the current processing identifier.
After receiving the downlink data packet, the access network device may obtain a network for sending the downlink data packet according to the identifier carried in the downlink data packet, and then determine a processing mode of the downlink data packet according to the configured corresponding relationship of the processing identifier and the processing identifier on the downlink data packet.
For example, when the processing identifier indicates the priority of each downlink data packet, the processing manner of the downlink data packet includes priority processing, later processing or dropping.
215. And the access network equipment processes the downlink data packet.
Optionally, in step 212, the SGW may add, after receiving the downlink data packet, the network identifier for sending the downlink data packet or the location information of the PGW for sending the downlink data packet in the data packet, without the MME carrying the location information of the home network identifier of the user equipment or the PGW when sending the initial context request or the attach accept request to the access network equipment in step 206. For example, as shown in the format of fig. 3, the location information of the user equipment home network identifier or the PGW is added to a GTP-U (General Packet Radio System tunneling protocol) Packet header.
It should be noted that the processing identifier may be a priority identifier or a service type identifier, etc. When the processing identifier is the priority identifier, the access network device may determine the processing mode of the downlink data packet according to the priority level corresponding to the processing identifier, for example, the downlink data packet with the higher priority level may be processed preferentially, and the downlink data packet with the lower priority level may be buffered or dropped. When the processing identifier is the service type identifier, the access network device may determine the processing mode of the downlink data packet according to the service type class corresponding to the processing identifier, for example, the downlink data packet with the higher service type class may be processed preferentially, and the downlink data packet with the lower service type class may be processed temporarily or dropped. When the processing identifier is the data stream identifier, the access network device may determine a processing mode of the downlink data packet according to the data stream type level corresponding to the processing identifier, for example, when the processing identifier is 1, the packet loss of the data stream is 15%; when the processing identifier is 2, the packet loss of the data stream is 30%. The priority level, the service type level and the data stream identification level are preset.
It should be noted that the embodiment of the present invention may also be used in a scenario where the user equipment is in a roaming state, but a PLMN to which the PGW gateway device belongs is the same as a VPLMN in which the user equipment is located.
In the prior art, after a downlink data packet arrives at an access network of a roaming operator, the roaming operator defines that a generated data packet processing identifier may be different from an attribution, and when the roaming access network processes the downlink data packet from an attribution gateway device, the data packet is processed according to the processing rule of the roaming processing identifier and the processing identifier of the downlink data packet, so that the data packet cannot be processed normally. Compared with the prior art, in the embodiment of the invention, in the process of attaching the user equipment to the roaming network, the access network equipment configures the corresponding relationship between the processing identifier of the home network and the processing identifier of the roaming network, the request sent to the access network equipment by the MME carries the identifier of the home network, when a downlink data packet is processed, the processing mode of the downlink data packet is determined according to the processing identifier of the downlink data packet and the configured corresponding relationship, and then the downlink data packet is processed. The access network equipment determines the network for sending the data packet according to the indication information of the downlink data packet, and further corresponds the processing identifier of the downlink data packet to the user-defined processing identifier of the roaming network operator according to the corresponding relation to determine the processing mode of the downlink data packet, so that the access network equipment can correctly process the downlink data packet.
Still another embodiment of the present invention provides a method for processing user data, as shown in fig. 4, where a user equipment is in a roaming network, and taking a process of establishing a dedicated bearer between the roaming network and a home network as an example, an access network device of the roaming network configures a corresponding relationship between a processing identifier of the roaming network for bearer connection and a processing identifier of the home network, and the method includes:
301. the PGW sends a create bearer request to the SGW.
302. The SGW sends a create bearer request to the MME.
303. The MME sends a bearer establishment request or a session management request to the access network equipment.
The MME sends a bearer establishment request or a session management request to the access network device, where the bearer establishment request or the session management request includes an identifier of a network to which a PGW to which the bearer is connected belongs and/or location information of the PGW to which the bearer is connected.
304. And the access network equipment sends a radio resource control connection reconfiguration message to the UE.
305. And the UE sends a radio resource control connection reconfiguration completion message to the access network equipment.
306. And the access network equipment sends a bearer establishment response to the MME.
It should be noted that, after the dedicated bearer is established, steps 307 to 312 are processing procedures for the downlink data packet, which are the same as the procedures described in steps 210 to 215, and are not described herein again.
307. And the PGW identifies the processing identification of the data packet in the downlink data packet.
308. And the PGW sends a downlink data packet to the SGW.
309. And the SGW adds a flag bit for the downlink data packet.
310. And the SGW sends a downlink data packet to the access network equipment.
311. The access network equipment determines the correct processing mode of the current processing identifier.
312. The access network equipment performs differentiated processing on the data packets.
Optionally, in step 309, after receiving the downlink data packet, the SGW may add, to the data packet, the network identifier for sending the downlink data packet or the location information of the PGW for sending the downlink data packet, without the MME carrying the home network identifier of the user equipment or the location information of the PGW when sending the initial context request or the attach accept request to the access network equipment in step 303. For example, an identifier of a network to which the PGW connected to the bearer belongs or location information of the PGW connected to the bearer is added to the GTP-U packet header.
It should be noted that the processing identifier may be a priority identifier or a service type identifier, etc. When the processing identifier is the priority identifier, the access network device may determine the processing mode of the downlink data packet according to the priority level corresponding to the processing identifier, for example, the downlink data packet with the higher priority level may be processed preferentially, and the downlink data packet with the lower priority level may be buffered or dropped. When the processing identifier is the service type identifier, the access network device may determine the processing mode of the downlink data packet according to the service type class corresponding to the processing identifier, for example, the downlink data packet with the higher service type class may be processed preferentially, and the downlink data packet with the lower service type class may be processed temporarily or dropped. When the processing identifier is the data stream identifier, the access network device may determine a processing mode of the downlink data packet according to the data stream type level corresponding to the processing identifier, for example, when the processing identifier is 1, the packet loss of the data stream is 15%; when the processing identifier is 2, the packet loss of the data stream is 30%. The priority level, the service type level and the data stream identification level are preset.
