Abstract
Description
Technical Field
[0001] This application relates to the field of packet data service technology, and more specifically, to a PDP bearer activation method and apparatus. Background Technology
[0002] In mobile communication networks, QoS cells are the basic units used to negotiate Quality of Service parameters between the network and terminals. The structure of a QoS cell includes multiple parameters, such as Delay class, Reliability class, Peak throughput, Precedence class, and Mean throughput, which specifically describe the latency, reliability, peak and average throughput, and priority requirements of data services. These parameters have different encoding rules and interpretations depending on the data transmission direction (from terminal to network or from network to terminal) and the supported protocol version (such as R97 / 98 or R99). QoS attributes have different definitions and expressions in different protocol versions. Specifically, there is a mapping relationship between QoS parameters in R97 / 98 and those in R99. For example, the Delay class and Reliability class parameters in R97 / 98 map to Traffic class and SDU error ratio in R99. This mapping ensures interoperability between different network versions, but it also introduces additional parameter negotiation and conversion logic, increasing signaling overhead and processing complexity.

[0033] In the above operating environment, this application provides an embodiment of a PDP bearer activation method. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0034] Figure 2 This is a flowchart of a PDP bearer activation method according to an embodiment of this application, such as... Figure 2As shown, the method includes the following steps:
[0035] Step S202: Obtain a service quality information element with a preset structure, wherein the service quality information element with the preset structure is an information element from the service quality information element standard template with at least one of the following fields deleted: latency level field, reliability level field, peak throughput field, priority level field, and average throughput field;
[0036] Step S204: Construct a Packet Data Protocol (PDP) activation request message based on the Quality of Service (QoS) information element;
[0037] Step S206: Send the PDP activation request message to the network side to complete the activation of the PDP bearer.
[0038] Through steps S202 to S206 above, a service quality element with a preset structure is obtained. This preset structure is a service quality element derived from a standard service quality element template by removing at least one of the following fields: latency level, reliability level, peak throughput, priority level, and average throughput. A Packet Data Protocol (PDP) activation request message is constructed based on the service quality element. The PDP activation request message is then sent to the network side to activate the PDP bearer. By removing redundant information from the service quality element, the operation related to service quality element parameters is simplified, thereby saving valuable air interface resources and solving the technical problem of low air interface resource utilization caused by sending excessive redundant information in related technologies. This will be explained in detail below.
[0039] In the technical solution provided by step S202 of the above-mentioned PDP bearer activation method, the specific steps for obtaining a service quality information element with a preset structure, wherein the service quality information element with the preset structure is an information element from the service quality information element standard template with at least one of the following fields deleted: latency level field, reliability level field, peak throughput field, priority level field, and average throughput field, are as follows: obtaining a construction method, wherein the construction method includes: a first method of construction by deleting redundant fields in the service quality information element standard template and a second method of construction by setting the redundant fields in the service quality information element standard template to zero; constructing a service quality information element template with a preset structure according to the construction method; filling the preset structure with the pre-obtained service quality information element parameters to obtain the service quality information element with the preset structure. By constructing the service quality information element with the preset structure, redundant information in the service quality information element is deleted or set to zero, avoiding excessive redundant information in the information to be sent, thereby improving the utilization rate of air interface resources.
[0040] It should be noted that the QoS information element definition (service quality information element standard template) in the relevant technologies is shown in Table 1, and Table 2 is the Chinese translation of Table 1.
[0041] Table 1
[0042]
[0043] Table 2
[0044]
[0045] It should be noted that among the various parameters in the QoS cell, some are attributes only for the R97 / 98 version, while others are attributes only for the R99 version. There is a mapping relationship between the R97 / 98 and R99 attribute parameters. For example, the Delayclass parameter is only an R97 / 98 attribute and can be mapped to the Traffic class and Traffic handling priority parameters in the R99 version. Similarly, the Reliability class parameter is only an R97 / 98 attribute and can be mapped to the SDU error ratio, Residual BER (bit error ratio), and Delivery of erroneous SDUs parameters in the R99 version. Finally, the Peak throughput parameter is only an R97 / 98 attribute and can be mapped to the Maximum bitrate parameter in the R99 version. The Precedence class parameter is only an attribute of the R97 / 98 version and can be mapped to the Allocation / Retention priority parameter and Priority Level of Evolved Allocation / Retention priority parameter of the R99 version. Note that these two parameters are not present in the QoS structure of the R99 version, and they are not negotiated directly between the terminal and the network.
[0046] The protocol clarifies that the UE is unaware of the allocation / retention priority parameters, so the UE can simply set the precedence class parameter in R97 / 98 to "subscribed," i.e., all zeros. The mean throughput parameter is only an attribute of R97 / 98, always taking the value 31, and there is no corresponding parameter attribute in R99. Based on the above analysis results, this application proposes a service quality information cell template with a preset structure.
[0047] In some embodiments of this application, constructing the preset structure according to the construction method includes: when the construction method is the first method, deleting the latency level field, reliability level field, peak throughput field, priority level field, and average throughput field from the service quality element standard template, and deleting a specified byte from the service quality element standard template to obtain the preset structure. By deleting the fields, the service quality element is simplified, avoiding excessive redundant information in the information to be sent and improving the utilization rate of air interface resources.
[0048] According to some optional embodiments of this application, redundant fields are trimmed. In some embodiments of this application, five parameters—Delay class, Reliability class, Peak throughput, Precedence class, and Mean throughput—are deleted from the QoS information element definition. At the same time, the original 3rd, 4th, and 5th bytes are deleted, as shown in Table 3. Table 4 is a Chinese translation of Table 3. The overall QoS information element is reduced by 3 bytes.
[0049] Table 3
[0050]
[0051] Table 4
[0052]
[0053]
[0054] In some communication systems, such as satellite systems, network devices do not support the QoS parameters in R97 / 98 versions, but instead directly negotiate services based on the R99 protocol version. In this scenario, parameters specific to R97 / 98 versions (such as Delayclass and Reliability class) become redundant information in air interface signaling, not only having no practical use but also occupying valuable channel resources.
[0055] In different satellite communication systems, the final 4-byte extended-2 definition is not present in the QoS cell definition, and the cell structure differs slightly from the diagram above; however, the method of this embodiment can be used uniformly. When the terminal constructs uplink messages such as PDP activation requests, it encodes them according to the new QoS cell structure, no longer encoding the five parameters such as Delay class; the first byte of the value field contains the three parameters such as Traffic Class. When the terminal receives downlink messages such as PDP activation acceptance, it decodes them according to the new QoS cell structure, no longer decoding the five parameters such as Delay class; the first byte of the value field contains the three parameters such as Traffic Class. After the terminal's internal NAS layer obtains the QoS parameters, when configuring the QoS parameters to the lower layer, the relevant configuration operations for the five parameters such as Delay class are deleted. When the network receives uplink messages such as PDP activation requests, it decodes them according to the new QoS cell structure, no longer decoding the five parameters such as Delay class; the first byte of the value field contains the three parameters such as Traffic Class. When the network constructs downlink messages such as PDP activation acceptance, it encodes them according to the new QoS cell structure, no longer encoding the five parameters such as Delay class; the first byte of the value field contains the three parameters such as Traffic Class. The R99 version SGSN network element on the network side no longer interacts with the R97 / 98 version SGSN network element for parameter mapping.
[0056] In some embodiments of this application, constructing the service quality element with the preset structure according to the construction method includes: when the construction method is the second method, deleting the latency level field, reliability level field, peak throughput field, priority level field, and average throughput field from the service quality element standard template, and setting a specified byte in the service quality element standard template as a reserved item to obtain the preset structure. By deleting the fields and setting the bytes to zero, the service quality element is simplified, avoiding excessive redundant information in the information to be sent and improving the utilization rate of air interface resources.
[0057] According to some alternative embodiments of this application, the redundancy parameter is set to zero. In some embodiments of this application, five parameters—Delay class, Reliability class, Peak throughput, Precedence class, and Mean throughput—are deleted from the QoS cell definition, while the original 3rd, 4th, and 5th bytes are retained and set as the spare item, and the overall byte count of the QoS cell remains unchanged. As shown in Table 5, Table 6 is the Chinese translation of Table 5.
[0058] Table 5
[0059]
[0060] Table 6
[0061]
[0062]
[0063] It should be noted that in different communication systems, the final 4-byte extended-2 definition is not present in the QoS cell definition, and the cell structure is slightly different from the above diagram; however, the method of this embodiment can be used uniformly. When the terminal constructs uplink messages such as PDP activation requests, it encodes according to the new QoS cell structure, no longer encoding the 5 parameters such as Delay class, but instead filling the 3-byte spare field with 0; when the terminal receives downlink messages such as PDP activation acceptance, it decodes according to the new QoS cell structure, no longer decoding the 5 parameters such as Delay class, but instead carrying the 3-byte spare field with 0; after the terminal's internal NAS layer obtains the QoS parameters, when configuring the QoS parameters to the lower layer, it deletes the relevant configuration operations for the 5 parameters such as Delay class. When the network receives uplink messages such as PDP activation requests, it decodes them according to the new QoS cell structure, no longer decoding the five parameters such as Delay class, but instead using a fixed 3-byte spare field carrying 0; when the network constructs downlink messages such as PDP activation acceptance, it encodes them according to the new QoS cell structure, no longer encoding the five parameters such as Delay class, but instead using a fixed 3-byte spare field filled with 0; the R99 version SGSN network element on the network side no longer interacts with the R97 / 98 version SGSN network element for parameter mapping.
[0064] In some embodiments of this application, constructing a Packet Data Protocol (PDP) activation request message based on the aforementioned Quality of Service (QoS) elements includes: filling pre-acquired QoS element parameters into the preset structure to obtain QoS elements of the preset structure, wherein the first byte of the value field of the QoS element in the preset structure is a target parameter, and the target parameter includes: service type, sequential transmission, and error SDU transmission handling; inserting the QoS elements of the preset structure into the template of the PDP activation request message to obtain the PDP activation request message.
[0065] In some embodiments of this application, constructing a Packet Data Protocol (PDP) activation request message based on the service quality information element of the preset structure includes: filling the preset structure with pre-acquired service quality information element parameters to obtain the service quality information element of the preset structure, wherein the reserved bit in the specified byte of the service quality information element of the preset structure is fixedly set to zero; inserting the service quality information element of the preset structure into the template of the PDP activation request message to obtain the PDP activation request message.
[0066] In some embodiments of this application, after sending the PDP activation request message to the network side, the method further includes: receiving a PDP activation acceptance message sent by the network side, wherein the PDP activation acceptance message is obtained according to the service quality information element encoding of the preset structure. By constructing the service quality information element of the preset structure, excessive redundant information in the information to be sent is avoided, thereby improving the utilization rate of air interface resources.
[0067] For example, if an IoT terminal wants to transmit real-time monitoring data through the Tiantong satellite network, it first acquires a specific set of Quality of Service (QoS) cell parameters. These parameters may include service type (e.g., real-time monitoring), sequential transmission requirements (data packets must be received in order to avoid out-of-order delivery), and error SDU transmission handling (e.g., retransmission strategies or error detection methods). Next, the terminal fills these parameters into a preset QoS cell structure. The first byte of the structure's value field is assigned a target parameter, which integrates the service type, sequential transmission, and error SDU handling requirements. Then, this preset structure containing customized QoS parameters is inserted into a PDP activation request message, forming a complete message template. This PDP activation request message is sent to the network, which, based on the QoS cell requirements in the message, allocates appropriate resources to the terminal and establishes a data channel that meets specific performance standards.
[0068] As some optional embodiments of this application, a service quality information element with a preset structure is obtained, wherein the service quality information element with the preset structure is an information element from the service quality information element standard template with at least one of the following fields deleted: latency level field, reliability level field, peak throughput field, priority level field, and average throughput field; a Packet Data Protocol (PDP) activation accept message is constructed based on the service quality information element with the preset structure; after receiving the PDP activation request message sent by the terminal side, the PDP activation accept message is sent to the network side to complete the activation of the PDP bearer.
