Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to an apparatus, method, and system for transmitting an upstream data stream. Background technique

Based on the development needs of the evolution network, the 3rd Generation Partnership Project ("3GPP") defines the Policy and Charging Control (PCC) architecture. Based on the PCC architecture, the evolved network can formulate a corresponding Quality of Service (QoS) for the detected different service data flows to ensure the QoS of the user service.

Generally, in the PCC architecture, a Policy and Charging Rules Function ("PCRF") is mainly based on an operator policy, restrictions on user access to the network, user subscription data, and services currently being performed by the user. The business information of the data stream and other factors are formulated into corresponding strategies. This strategy is called PCC rule. The Policy and Charging Enforcement Function (PCEF) is mainly used to enforce PCC rules to guarantee the QoS of user services.

Specifically, in order to ensure the QoS of the user service, the service data stream received by the user equipment needs to pass through the PCEF, and the PCEF binds the service data stream to the corresponding bearer according to the QoS of the service data flow. For example, the PCEF can bind the service data flow with the same QoS to the same bearer to ensure that the service data flow can enjoy the service quality corresponding to the Qo S of the service data flow.

When the PCRF sends a PCC rule to the PCEF, the rule includes information about the descriptor of the service data stream in addition to the QoS. The descriptor information may include quintuple information, such as a source IP address, a destination IP address, a source port number, a destination port number, and a protocol number. After the bearer binding is completed, the PCEF establishes a corresponding service data flow template for each bearer, where the service data flow template includes descriptor information of all service data flows corresponding to the bearer. In this way, when receiving the downlink service data flow, the PCEF can The descriptor information of the downlink service data stream is matched with the data flow template to find a corresponding bearer, and the service data flow is sent on the bearer. The service data flow may be an uplink service data flow or a downlink service data flow.

The current implementation scheme can implement the binding of the uplink service data flow to the bearer for the uplink service data flow, but in this implementation scheme, the UE cannot determine the corresponding uplink service data flow without using the quintuple. Carry and carry the transmission of the uplink service data stream.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without making creative labor are within the scope of the present invention.

It should be understood that the technical solution of the embodiments of the present invention can be applied to various communication systems, for example, a Global System of Mobile communication ("GSM") system, Code Division Multiple Access (CDMA). ") System, Wideband Code Division Multiple Access ("WCDMA") system, General Packet Radio Service ("GPRS"), Long Term Evolution (LTE) System, LTE Frequency Division Duplex ("FDD") system, LTE Time Division Duplex ("TDD"), Universal Mobile Telecommunication System (UMTS) , Worldwide Interoperability for Microwave Access ("WiMAX") communication system.

FIG. 1 is a schematic diagram of a network architecture based on an embodiment of the present invention. It should be understood that the embodiments of the present invention may also be based on other network architectures, which are not limited by the embodiments of the present invention.

As shown in FIG. 1, the UE, the Mobility Management Entity ("B"), the Serving Gateway (SGW), and the Packet Data Network Gateway (referred to as "PGW"), Policy and Charging Enforcement Fucntion (PCEF), Policy and Charging Rules Function ("PCRF"), access network In the network architecture consisting of the Access Network Discovery Support Functions (ANDSF), the PCRF is mainly used to formulate policies. The policy usually includes how to select the corresponding bearer for the service data flow. PCEF is mainly used to implement the policy formulated by the PCRF to detect the service data flow and ensure the service quality of the service data flow. Generally, The PCEF binds the service data flow to the corresponding bearer of the QoS according to the QoS of the service data flow. Normally, PCEF is combined with a network management device, such as a PGW.

In the prior art, in the downlink direction of data transmission, corresponding load binding and matching can also be performed according to the application type of the service data flow.

For example, the current PGW, the gateway containing PCEF, can integrate traffic detection ( Traffic

The detection function (referred to as "TDF") entity, through which the TDF entity can detect the application type of the service data flow. Therefore, the descriptor information of the service data flow does not include a quintuple, but may be an application type including the service data flow. . Correspondingly, the application type can be included in the established service data flow template. Therefore, when receiving the downlink service data flow, the PCEF can determine the corresponding bearer according to the application type corresponding to the downlink data flow, so as to ensure that the service data flow enjoys the service quality corresponding to the QoS of the service data flow.

For the above described processing scheme for the application type, the scheme is for the processing of the downlink traffic data stream. In the uplink direction, if the UE cannot know the application type of the uplink service data flow, the corresponding bearer selection cannot be performed based on the application type, and only the selection of the five-tuple in the prior art can be used.

To this end, the following embodiments are provided in the embodiment of the present invention, so that the UE can still determine the bearer corresponding to the uplink service data flow and perform the transmission of the upper service data stream without using the quintuple.

Example 1

1. The PCEF notifies the UE of the reflective indication.

The transparent indication is used to notify the UE to use the bearer to transmit the uplink data stream corresponding to the bearer downlink data stream.

Specifically, after receiving the IP-CAN session modification request message of the PCRF, the PCEF sends a create bearer request message including the reflective indication to the SGW; the SGW sends a create bearer request message including the reflective indication to the MME; The UE sends a session management request message containing the reflective indication. The embodiment of the present invention does not limit the specific manner in which the reflective indication is sent. For example, the reflective indication may be included in the PCO cell.

In addition, the step may further include: in the process of establishing the bearer, including the transparent indication in the uplink service data flow template established for the uplink direction.

2. The UE acquires the transparent indication.

Specifically, the UE receives the session management request message sent by the MME, and obtains the transparent indication from the message.

If the PCEF is to notify the UE of the reflective indication by using the uplink service data flow template, the UE may directly obtain the reflective indication from the uplink service data flow template, and determine, by the UE, the downlink service corresponding to the uplink service data flow to be sent. Data flow, and determining the bearer corresponding to the downlink service data flow.

Specifically, the bearer corresponding to the downlink service data flow is determined according to the descriptor information such as the IP address/port number of the downlink service data flow and the correspondence between the descriptor information and the bearer. For example, the service data flow template corresponding to each bearer may be searched according to the descriptor information of the downlink service data flow. If the descriptor information is found in a service data flow template, the service data flow template corresponds to The bearer is the bearer corresponding to the downlink service data flow.

4. The UE performs the transmission of the uplink service data stream by using the bearer determined in step 3. For the foregoing embodiment, the UE does not need to know the application type, and does not need to determine the bearer in the uplink direction according to the application type, and does not need to use the quintuple to search for the bearer, but directly uses the bearer of the downlink service data flow as the bearer. The carrying of the uplink service data stream corresponding to the downlink service data stream is obviously more convenient for the UE side processing.

Example 2

In the current communication system, there are two types of bearer control modes, one controlled by the network side and the other controlled by the UE side.

For the network side control mode, when the network side establishes a bearer, the network side can know the application type of the service data flow, so that the corresponding bearer can be specified for the service type. For the UE side control mode, in this mode, the operator usually cannot control, such as QQ service. In this way, only after the network resource is successfully established, after the service is running, the TDF function detects the application type of the service data flow, and then determines which bearer the service data flow of the application type should be placed on, if To use other bearers other than the bearers used when the network resources are established, the bearer modification process needs to be re-initiated, so that the UE can know which bearer the current service data stream of the UE should use. Obviously, this kind of processing is easy to increase the interaction of signaling.

In this embodiment, for the service controlled by the UE, when the UE initiates the resource application, the UE sends the application type information of the service data flow to the network side, so that the network side can perform the allocation according to the application type.

Specifically,

1. The UE sends a resource bearer application request message to the network side device, where the request message carries an application identifier (application id) of the service data stream.

The application identifier is specifically used to identify the application type of the service data flow. The message may also include the QCI of the traffic stream.

The UE may obtain the application identifier through the ANDSF. Specifically, the ANDSF can obtain an application identifier of the service data stream to be sent by the UE, and send the identifier to the UE.

2. The network side receives the resource bearer application request message, and obtains the application identifier in the request message.

Specifically, the MME may receive a bearer resource request request message initiated by the UE, and

The SGW sends a bearer resource command message; the SGW sends a bearer resource command message to the PCEF; and the PCEF sends an IP-CAN session modification indication to the PCRF.

If the resource bearer request message sent in step 1 above includes the service data stream

For the QCI, the QCI may also be included in each of the above messages transmitted by the network side.

3. The network side allocates corresponding QoS for the service data flow according to the application identifier, and according to the

QoS binds the service data flow to the corresponding bearer. Specifically, the PCRF of the network side may allocate corresponding QoS for the service data flow according to the application identifier, and send the allocated QoS to the PCEF through an IP-CAN session confirmation message; the PCEF performs the service according to the QoS. The data stream is bound to the corresponding bearer.

The PCEF may specifically bind the service data flow with the same QCI/ARP to the same bearer.

4. The UE transmits the uplink service data flow according to the bearer determined in step 3.

Specifically, if the corresponding bearer is directly determined for the uplink service data flow in step 3, in step 4, the UE may directly transmit the uplink service data stream on the bearer.

If the corresponding bearer is determined for the downlink service data flow in the step 3, the UE may use the implementation scheme of the foregoing Embodiment 1 to process the bearer of the uplink service data flow corresponding to the downlink service data flow, where Let me repeat.

In the above embodiment, the UE directly sends the application identifier of the service data flow to the network side, and the network side can directly allocate the corresponding QoS according to the application identifier, and bind the bearer to the service data flow based on the allocated QoS, so that When the bearer is bound to the service data flow, the application type of the service data flow is considered, so that the network side can quickly bind the service data flow to the bearer according to the application type without increasing the signaling overhead.

Example 3

1. The UE obtains the application identifier of the service data flow through the ANDSF.

Specifically, since the ANDSF can obtain the application identifier of the service data flow of the UE, the application identifier of the service data flow of the UE can be sent by the AND SF to the UE.

The application identifier may be an identifier, that is, corresponding to one service data flow, or may be a list, that is, corresponding to multiple service data flows.

2. The UE determines a correspondence between the application identifier and the QCI of the service data flow.

3. Before sending the uplink service data flow, the UE determines an application identifier corresponding to the uplink data flow.

The UE determines the QCI corresponding to the uplink service data flow according to the determined correspondence relationship and the determined application identifier, and determines the QCI according to the QCI and the corresponding relationship between the QCI and the bearer. The bearer used by the upstream service data stream.

The correspondence between the QCI and the bearer may be established by the PCEF and sent to the UE. Specifically, a correspondence between the bearer meeting the QCI requirement and the QCI may be established.

5. The UE sends the uplink service data flow according to the bearer determined in step 4.

For step 5, it is similar to the last step of the foregoing embodiment 2.

Specifically, if the corresponding bearer is directly determined for the uplink service data flow in the foregoing step 4, in the step 5, the UE may directly transmit the uplink service data stream on the bearer.

If the corresponding bearer is determined for the downlink service data flow in the step 4, the UE may perform the processing according to the implementation scheme of the foregoing Embodiment 1 when determining the bearer of the uplink service data flow corresponding to the downlink service data flow.

The above three implementation manners are specifically described below with reference to the accompanying drawings and specific embodiments.
