For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present invention, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.
The first embodiment of the invention relates to a policy and charging control method, which is applied to a policy and charging rule function network element PCRF, and in the embodiment, a request message of an application function network element AF is received, wherein the request message comprises media stream information and N request bandwidths; wherein, the N request bandwidths respectively correspond to different radio access technologies RAT, and N is a natural number greater than 1; generating policy and charging control PCC rules according to the request message, wherein the generated PCC rules comprise: PCC rules corresponding to the RAT currently employed by the user terminal. The embodiment can reduce signaling overhead. Implementation details of the policy and charging control method of the present embodiment are specifically described below, and the following is merely provided for convenience of understanding, and is not necessary to implement the present embodiment.
The policy and charging control method in this embodiment is as shown in fig. 1:
step 101: receiving a request message of an application function network element AF, wherein the request message comprises media stream information and N request bandwidths; the N request bandwidths respectively correspond to different Radio Access Technologies (RATs), and N is a natural number greater than 1.
Specifically, the PCRF receives a request message sent by the AF, where the request message is used to request the PCRF to provide network resource guarantee for AF media streaming, and the request message carries media streaming information and N request bandwidths. Each request bandwidth contains an uplink bandwidth parameter value and a downlink bandwidth parameter value, and one request bandwidth is applicable to one RAT, for example, an uplink request bandwidth=1 Mbps of request bandwidth 1, a downlink request bandwidth=1 Mbps, and the corresponding RAT is UTRAN (3G); the uplink request bandwidth=10 Mbps and the downlink request bandwidth=10 Mbps of the request bandwidth 2, and the corresponding RAT is E-UTRAN (4G).
Step 102: generating policy and charging control PCC rules according to the request message, wherein the generated PCC rules comprise: PCC rules corresponding to the RAT currently employed by the user terminal.
Specifically, the PCRF generates at least PCC rules corresponding to the current RAT employed by the user terminal according to the bandwidth parameter values of the N requested bandwidths corresponding to the different RATs in the request message. The generated PCC rule may be sent to the PCEF for execution, where the PCEF establishes a dedicated bearer with the user terminal according to the PCC rule, and is configured to transmit the AF media stream of the sending request message, thereby ensuring transmission of the AF media stream.
It should be noted that this embodiment is applicable to PCC architectures of EPC (Evolved Packet Core Network ) and 5GC (5G Core Network, 5 th generation mobile communication Core Network) defined by the third generation partnership project.
Compared with the prior art, in the embodiment of the invention, the policy and charging rule function network element PCRF receives the request message of the application function network element AF, the request message comprises media stream information and N request bandwidths, the N request bandwidths respectively correspond to different radio access technologies RATs, and then policy and charging control PCC rules are generated according to the request message. By receiving a request message carrying a plurality of bandwidth requests corresponding to different RATs, when a subsequent user terminal adopts a changed RAT and a PCRF is required to generate a new PCC rule according to the changed RAT, the PCRF does not need to perform signaling interaction with an AF to obtain the request bandwidth corresponding to the changed RAT, but can acquire the request bandwidth corresponding to the changed RAT from the request message received before and generate the new PCC rule, so that the signaling interaction times between the PCRF and the AF are reduced, the signaling cost of the PCC architecture is reduced, and network resources are saved.
A second embodiment of the present invention relates to a policy and charging control method. The second embodiment is further refined based on the first embodiment, in the step of generating policy and charging control PCC rules according to the request message, N PCC rules are respectively generated according to N request bandwidths in the request message, where the N PCC rules are in one-to-one correspondence with the N request bandwidths; the second embodiment further includes, after the step of generating the policy and charging control PCC rules according to the request message, sending N PCC rules to the PCEF, where the PCEF executes the PCC rules corresponding to the RAT currently adopted by the user terminal.
As shown in fig. 2, the policy and charging control method in this embodiment specifically includes:
step 201: receiving a request message of an application function network element AF, wherein the request message comprises media stream information and N request bandwidths; wherein the N request bandwidths respectively correspond to different radio access technologies RATs, and N is a natural number greater than 1.
Step 201 is substantially the same as step 101 in the first embodiment, and is not repeated here.
Step 202: generating N PCC rules according to N request bandwidths in the request message, wherein the N PCC rules are in one-to-one correspondence with the N request bandwidths, and the generated PCC rules comprise: PCC rules corresponding to the RAT currently employed by the user terminal.
Specifically, the PCRF generates PCC rules according to the bandwidth parameter values contained in each requested bandwidth contained in the received request message, respectively. Since each requested bandwidth corresponds to one RAT, each PCC rule also corresponds to one RAT. The generated PCC rules comprise PCC rules corresponding to the RAT adopted by the user terminal currently.
Step 203: and sending the N PCC rules to a PCEF, and executing the PCC rules corresponding to the RAT adopted by the user terminal by the PCEF.
Specifically, the PCRF sends all the N PCC rules generated in the previous step to the PCEF, and the PCEF determines, according to the RAT currently adopted by the user terminal, the PCC rule corresponding to the adopted RAT among the N PCC rules and executes the PCC rules, and establishes a dedicated bearer with the user terminal, for transmitting the AF media stream of the sending request message, so as to ensure the transmission of the AF media stream.
Further, when the PCEF subsequently receives the RAT change event of the user terminal, one PCC rule corresponding to the RAT currently adopted by the user terminal is selected and executed from the N previously received PCC rules, and the new PCC rule can be executed by using the changed RAT without reporting the RAT change event of the user terminal to the PCRF or waiting for the PCRF to issue the new PCC rule.
In an actual application scenario, the interaction flow of the PCRF, the AF, and the PCEF, which execute the policy and charging control method in this embodiment, is shown in fig. 3, and includes:
step 1: the AF requests the PCRF to provide network resource guarantee for media stream transmission, and the AF sends a request message to the PCRF, wherein the request message comprises media stream information and N request bandwidths corresponding to different RATs. For example, N is equal to 2, and the request bandwidths are respectively:
request bandwidth 1: the corresponding RAT is UTRAN (3G), uplink request bandwidth=1 Mbps, downlink request bandwidth=1 Mbps;
request bandwidth 2: the corresponding RAT is E-UTRAN (4G), upstream requested bandwidth=10 Mbps, downstream requested bandwidth=10 Mbps.
Step 2: the PCRF receives the request message sent by the AF and generates N PCC rules corresponding to different RATs according to N request bandwidths corresponding to different RATs in the request message. For example, the PCRE receives the request message including 2 request bandwidths in step 1, and in this step, generates two PCC rules according to the request message, where the two PCC rules are respectively:
PCC rule 1: the corresponding RAT is UTRAN (3G), uplink request bandwidth=1 Mbps, downlink request bandwidth=1 Mbps;
PCC rule 2: the corresponding RAT is E-UTRAN (4G), upstream requested bandwidth=10 Mbps, downstream requested bandwidth=10 Mbps.
Step 3: the PCRF issues a plurality of PCC rules corresponding to different RATs to the PCEF. For example, in step 2, the PCRF generates 2 PCC rules, and correspondingly, in this step, the PCRF issues all of the generated 2 PCC rules to the PCEF.
Step 4: the PCEF selects one PCC rule corresponding to the current RAT of the user terminal from the received N PCC rules to execute. For example, the PCEF receives the PCC rules 1 and the PCC rules 2 sent by the PCRF in step 3, in this step, it is determined that the current RAT of the user terminal is E-UTRAN (4G), and the PCEF selects to execute the PCC rules 2 corresponding to the RAT, and establishes a dedicated bearer with an uplink guaranteed bandwidth of 10Mbps and a downlink guaranteed bandwidth of 10Mbps between the user terminal, so as to transmit the media stream of the AF.
Step 5: the user terminal movement causes a RAT change and the PCEF receives a RAT change event. For example, the user terminal moves, causing the RAT of the user terminal to change from E-UTRAN (4G) to UTRAN (3G), at which point the PCEF receives the information of the RAT transmission change.
Step 6: and the PCEF selects one PCC rule corresponding to the current RAT of the user terminal from N PCC rules received before to execute according to the latest RAT. For example, according to the foregoing steps, the RAT of the user terminal is changed from E-UTRAN (4G) to UTRAN (3G), and the PCEF selects PCC rule 1 from the 2 PCC rules received before to execute, and adjusts the uplink guaranteed bandwidth of the AF media stream dedicated bearer to 1Mbps according to PCC rule 1, and adjusts the downlink guaranteed bandwidth to 1Mbps.
Compared with the first embodiment, in the present embodiment, the PCRF generates a plurality of PCC rules corresponding to different RATs according to the received request message, and sends all the generated PCC rules to the PCEF, so that when the subsequent RATs adopted by the user terminal change and the PCEF is required to execute the new PCC rules, the PCEF does not need to perform signaling interaction with the PCRF to acquire the new PCC rules, and can acquire and execute the PCC rules corresponding to the changed RATs from the plurality of previously received PCC rules, thereby reducing the signaling interaction times between the PCRF and the PCEF, and further reducing signaling overhead of the PCC architecture and saving network resources.
The third embodiment of the invention relates to a policy and charging control method. The third embodiment is substantially the same as the second embodiment, and is different in that in the step of generating policy and charging control PCC rules according to the request message, the present embodiment obtains a RAT currently adopted by the user terminal, determines a request bandwidth corresponding to the RAT currently adopted by the user terminal from N request bandwidths, and generates a PCC rule corresponding to the RAT currently adopted by the user terminal according to the determined request bandwidth; the third embodiment further includes, after the step of generating the policy and charging control PCC rule according to the request message, sending the generated PCC rule corresponding to the RAT currently adopted by the user terminal to the PCEF for implementation.
As shown in fig. 4, the policy and charging control method in this embodiment specifically includes:
step 301: receiving a request message of an application function network element AF, wherein the request message comprises media stream information and N request bandwidths; wherein, the N request bandwidths respectively correspond to different radio access technologies RATs.
Step 301 is substantially the same as step 101 in the first embodiment, and is not repeated here.
Step 302: acquiring the RAT currently adopted by the user terminal; and determining the request bandwidth corresponding to the RAT currently adopted by the user terminal from the N request bandwidths.
Specifically, the acquiring the RAT currently adopted by the user terminal includes: receiving the RAT currently adopted by the user terminal reported by the PCEF; or determining the RAT currently adopted by the user terminal according to the RAT change event reported by the PCEF. After receiving the request message, the PCRF determines a request bandwidth corresponding to the RAT adopted by the user terminal from N request bandwidths of the request message by receiving the RAT currently adopted by the user terminal reported by the PCEF; in addition, when the RAT adopted by the user terminal is changed, the PCRF acquires the RAT currently adopted by the user terminal by receiving the RAT change event of the user terminal reported by the PCEF, and determines a request bandwidth corresponding to the RAT adopted by the changed user terminal from the N request bandwidths of the request message.
Step 303: generating PCC rules corresponding to the RAT currently adopted by the user terminal according to the determined request bandwidth
Specifically, the PCRF generates the PCC rule by using the bandwidth parameter value in the requested bandwidth corresponding to the RAT currently employed by the user terminal as the bandwidth parameter value of the PCC rule, so that the generated PCC rule is applicable to the RAT currently employed by the user terminal.
Step 304: and sending the generated PCC rule corresponding to the RAT adopted by the user terminal to the PCEF for execution.
Specifically, the PCRF sends the PCC rule corresponding to the RAT currently adopted by the user terminal to the PCEF, and the PCEF receives and executes the PCC rule, and establishes a dedicated bearer with the user terminal, so as to be used for transmitting the AF media stream of the sending request message, thereby ensuring the transmission of the AF media stream.
In an actual application scenario, the interaction flow of the PCRF, the AF, and the PCEF, which execute the policy and charging control method in this embodiment, is shown in fig. 5, and includes:
step 1: the AF requests the PCRF to provide network resource guarantee for media stream transmission, and the AF sends a request message to the PCRF, wherein the request message comprises media stream information and N request bandwidths corresponding to different RATs. For example, N is equal to 2, and the request bandwidths are respectively:
request bandwidth 1: the corresponding RAT is UTRAN (3G), uplink request bandwidth=1 Mbps, downlink request bandwidth=1 Mbps;
request bandwidth 2: the corresponding RAT is E-UTRAN (4G), upstream requested bandwidth=10 Mbps, downstream requested bandwidth=10 Mbps.
Step 2: the PCRF acquires the current RAT of the user terminal according to the user terminal access information reported by the PCEF, and after receiving the AF request message, the PCRF determines the bandwidth parameter value of the PCC rule according to the current RAT of the user terminal, and generates the PCC rule for the AF media stream. For example, the PCRF knows that the current RAT of the user terminal is E-UTRAN (4G), uses the broadband parameter value in the request broadband 2 as the bandwidth parameter value of the PCC rule, determines the uplink guaranteed bandwidth of the PCC rule to be 10Mbps, and determines the downlink guaranteed bandwidth to be 10Mbps.
Step 3: the PCRF issues the generated PCC rules to the PCEF, and the PCEF installs and executes the PCC rules. For example, the PCEF receives the PCC rule generated in step 2, and establishes a dedicated bearer with an uplink guaranteed bandwidth of 10Mbps and a downlink guaranteed bandwidth of 10Mbps between the PCEF and the user terminal, so as to transmit the AF media stream.
Step 4: the user terminal moves to cause the RAT to change, and the PCEF receives the RAT change event and reports the RAT change event to the PCRF. For example, the ue moves, resulting in the RAT of the ue changing from E-UTRAN (4G) to UTRAN (3G), at which time the PCEF receives the RAT change information and reports the RAT change information to the PCRF.
Step 5: and the PCRF determines the bandwidth parameter value of the PCC rule according to the RAT adopted by the current user terminal and generates a new PCC rule. For example, when the RAT of the user terminal is switched to UTRAN (3G), the PCRF will request the broadband parameter value in broadband 1 as the bandwidth parameter value of the PCC rule, determine the uplink guaranteed bandwidth of the PCC rule to be 1Mbps, and the downlink guaranteed bandwidth to be 1Mbps.
Step 6: the PCRF issues the regenerated PCC rules to the PCEF, and the PCEF installs and executes the PCC rules. For example, the PCEF issues the PCC rule generated in step 5 to the PCEF, and the PCEF adjusts the uplink guaranteed bandwidth of the dedicated bearer for the AF media flow to 1Mbps according to the PCC rule, and adjusts the downlink guaranteed bandwidth to 1Mbps.
Compared with the prior art, in the embodiment, the PCRF generates a plurality of PCC rules corresponding to different RATs according to the received request message, and sends the PCC rules corresponding to the RATs adopted by the user terminal to the PCEF, so that when the subsequent RATs adopted by the user terminal are changed, the PCRF is required to generate new PCC rules according to the changed RATs and send the new PCC rules to the PCEF for execution, the PCRF does not need to perform signaling interaction with the AF to obtain the request bandwidth corresponding to the changed RATs, but can acquire the request bandwidth corresponding to the changed RATs from the request message received before and generate the new PCC rules, thereby reducing signaling interaction times between the PCRF and the AF, reducing signaling overhead of the PCC architecture, and saving network resources.
The above steps of the methods are divided, for clarity of description, and may be combined into one step or split into multiple steps when implemented, so long as they include the same logic relationship, and they are all within the protection scope of this patent; it is within the scope of this patent to add insignificant modifications to the algorithm or flow or introduce insignificant designs, but not to alter the core design of its algorithm and flow.
The fourth embodiment of the invention relates to a policy and charging control method, which is applied to an application function network element AF and comprises the following steps: sending a request message to a Policy and Charging Rules Function (PCRF), wherein the request message comprises media stream information and N request bandwidths; the N request bandwidths respectively correspond to different radio access technologies RATs, where N is a natural number greater than 1, so that the PCRF generates policy and charging control PCC rules according to the request message, and the generated PCC rules include: PCC rules corresponding to the RAT currently employed by the user terminal.
The policy and charging control method in this embodiment is as shown in fig. 6:
step 401: constructing a request message, wherein the request message comprises media stream information and N request bandwidths; the N request bandwidths respectively correspond to different radio access technologies RATs, and N is a natural number greater than 1.
Specifically, the AF constructs a request message, where the request message is used to request the PCRF to provide network resource guarantee for AF media streaming, and the request message carries media streaming information and N request bandwidths. Each request bandwidth contains an uplink bandwidth parameter value and a downlink bandwidth parameter value, and one request bandwidth is applicable to one RAT, for example, an uplink request bandwidth=1 Mbps of request bandwidth 1, a downlink request bandwidth=1 Mbps, and the corresponding RAT is UTRAN (3G); the uplink request bandwidth=10 Mbps and the downlink request bandwidth=10 Mbps of the request bandwidth 2, and the corresponding RAT is E-UTRAN (4G).
Step 402: sending a request message to the PCRF to enable the PCRF to generate PCC rules according to the request message, wherein the generated PCC rules comprise: PCC rules corresponding to the RAT currently employed by the user terminal.
