Example one
The invention realizes the intelligent energy-saving function of the network element in the communication network through different types of 5G network elements.
The intelligent energy-saving network of the different types of 5G communication network elements is applied to the architecture of the 5G core network shown in fig. 3, the composition schematic diagram of the intelligent energy-saving network is shown in fig. 4, the intelligent energy-saving network comprises two types of intelligent energy-saving groups, and a direct business relationship exists between the two types of intelligent energy-saving groups; each type of intelligent energy-saving group at least comprises one intelligent energy-saving network element, such as: the intelligent energy-saving network comprises an SMF intelligent energy-saving group and a UPF intelligent energy-saving group, wherein the SMF intelligent energy-saving group comprises at least one SMF intelligent energy-saving network element, and the UPF intelligent energy-saving group comprises at least one UPF intelligent energy-saving network element (when only one UPF intelligent energy-saving network element exists, at least one common UPF network element can be used for replacing work). The intelligent energy-saving network element is a network element capable of providing offline application according to the load condition of the intelligent energy-saving network element.
The SMF intelligent energy-saving group and the UPF intelligent energy-saving group can be replaced by other types of intelligent energy-saving groups as long as the two intelligent energy-saving groups have direct business relation, and the protection range of the invention is not influenced. The main functions of the intelligent energy-saving network comprise an offline application function, an offline approval function, an offline network element starting function, an awakened automatic operation function and the like.
The specific functions of the functions are described by taking an intelligent energy-saving network consisting of a UPF intelligent energy-saving group and an SMF intelligent energy-saving group as an example:
applying for a offline function: the UPF intelligent energy-saving network element automatically judges the self load condition, and applies for offline to the SMF intelligent energy-saving network element when the load is low (the high-low value of the load can be set); the SMF intelligent energy-saving network element can also apply for offline to the UPF intelligent energy-saving network element. The energy-saving interface protocol is applied for offline.
And (4) agreeing to the offline function: and when the SMF intelligent energy-saving network element receives the UPF intelligent energy-saving network element offline application information, making a judgment reply of whether to agree with the application of offline, and recording the address of the offline equipment.
And awakening the offline intelligent energy-saving network element starting function by the SMF intelligent energy-saving network element through an energy-saving interface protocol according to the address of the offline UPF intelligent energy-saving network element.
Awakened autorun function: and the UPF intelligent energy-saving network element receives the awakening of the SMF intelligent energy-saving network element, automatically operates, registers the service and provides the service.
The working principle of the intelligent energy-saving network is as follows:
the intelligent energy-saving network composed of the UPF intelligent energy-saving group and the SMF intelligent energy-saving group is also taken as an example for explanation:
the UPF intelligent energy-saving network element works and is distributed with services by the SMF intelligent energy-saving network element, and when the UPF intelligent energy-saving network element judges that the self load is less than a set value at night idle time and long time (which can be set for a long time) is not distributed with services or the service operation is less, the UPF intelligent energy-saving network element can give a request for getting off the line to the SMF intelligent energy-saving network element. A service quantity threshold may be set. And after the SMF intelligent energy-saving network element agrees, transferring the service of the UPF intelligent energy-saving network element to other UPF for processing. And after the awakening rule is met, the SMF intelligent energy-saving network element awakens the offline UPF intelligent energy-saving network element. The other UPF comprises other UPF intelligent energy-saving network elements or common UPF network elements.
Example two
The intelligent energy-saving method for the different types of 5G communication network elements is realized based on the intelligent energy-saving network of the first embodiment, the working process of the intelligent energy-saving method is shown as figure 6, and the method comprises the following steps:
step S1, a certain intelligent energy-saving network element (hereinafter referred to as a first intelligent energy-saving network element for convenience of description) in the intelligent energy-saving network applies for offline to different types of target intelligent energy-saving network elements having a direct business relationship with the certain intelligent energy-saving network element, and receives energy-saving application response information of the target intelligent energy-saving network element, and the first intelligent energy-saving network element selects the target intelligent energy-saving network element having the highest busy degree as a wake-up network element from among the energy-saving application response information, wherein the type of the response is that the target intelligent energy-saving network element agrees to offline.
Step S1 specifically includes:
step S101, the first intelligent energy-saving network element judges the self load condition, if the self load is less than the set standard, the energy-saving interface protocol is used for sending energy-saving off-line application information to different types of target intelligent energy-saving network elements which have direct business relation with the first intelligent energy-saving network element.
The intelligent energy-saving network composed of the UPF intelligent energy-saving group and the SMF intelligent energy-saving group shown in fig. 5 is taken as an example to illustrate that:
when the UPF intelligent energy-saving network element judges that the load of the UPF intelligent energy-saving network element is less than the reference (for example, the reference is set to be that the busy degree is less than 10% and lasts for 1 hour, or the busy degree is less than 10% and lasts for 0.5 hour, or the time exceeds 0 point at night, the reference of the load can be set according to the requirement, but not limited to the mode), the UPF intelligent energy-saving network element starts to take off the line, and sends energy-saving off-line application information to the SMF intelligent energy-saving network element which has a direct business relationship with the UPF intelligent energy-saving network element.
The energy-saving offline application information is provided with a wakeup rule. At present, the 5G interface and protocol of 3GPP do not have the protocol related to energy saving, and the invention defines the own energy saving interface protocol.
The customized energy-saving interface protocol is shown in the following table 1:
TABLE 1
Device type flag: defining the type of equipment, and if the equipment is a UPF intelligent energy-saving network element, defining the equipment as UPF; if the equipment is an SMF intelligent energy-saving network element, the equipment is defined as SMF; if the device is an AMF intelligent power saving network element, it is defined as AMF and so on. The user can define according to the network element types participating in intelligent energy saving.
Energy-saving group number: because different network elements are deployed at different positions, in different areas, and in different managed users, the same type of network elements in different areas may not be able to work in place of each other, so it is necessary to identify the network elements by numbers.
The energy-saving protocol content is as follows: including but not limited to energy saving offline application information, energy saving application response information, selected information, energy saving application re-service information, etc.
The energy saving interface protocol is sent by using UPD, and the hierarchical structure of the protocol is shown in FIG. 7.
In this step, the protocol type is energy-saving application offline, the energy-saving protocol content is the content of energy-saving offline application information, and the energy-saving offline application information includes the content in the following table 2:
TABLE 2
In this step, the first intelligent energy-saving network element sends the energy-saving application offline information for the first time, and the application flag is 0 for the reservation application (the first time).
The awakening rule carried in the energy-saving application offline information is described as follows:
the "condition control flag" is 1 byte (8 bits, from low bit1 to high bit8) and takes the following values:
bit1 and bit2 are all 0: the busy levels 1 and 2 determine the wake-up, regardless of the wake-up time.
bit1 ═ 1: and the busy degree 1 judges awakening, and simultaneously meets the requirement of conditional awakening time.
bit2 ═ 1: and the busy degree 2 judges awakening, and simultaneously meets the requirement of conditional awakening time.
bit3 ═ 1: and awakening when the condition awakening time requirement is met.
bit4 ═ 1: a wakeup party default rule is used.
bit5-bit 8: and (5) standby.
The default rule is a default value for setting a network element, and the default value setting is exemplified by: the busy level is greater than 50% and lasts for 1 hour or the busy level is greater than 80% and lasts for 0.5 hour, or the time exceeds 7 am, the default value can be set according to actual conditions, and is not limited to one setting.
In general, the busy level 2 is higher than the busy level 1, and the condition 2 duration is shorter than the condition 1 duration. Busy level 2 belongs to the emergency wake-up function and busy level 1 belongs to the general wake-up function.
The busy degree of the network element is calculated by the following formula:
the busy level is (the current traffic of the network element/the maximum supported traffic of the network element) X100%.
For the actual use of the network element calculation, the maximum traffic average value of several days can be taken to replace the "maximum supported traffic of the network element" to participate in the calculation. Therefore, different core services of each network element can be converted into busy degrees, and the energy-saving protocol can be used for various network elements.
For UPF, its busyness calculation is:
the UPF busy level is (number of sessions present/maximum supported session capacity) x 100%.
The "maximum supported session capacity" of the UPF may be set at factory deployment.
For SMF, SMF records the maximum number of established sessions per unit time (5 minutes) per day, saves 5 maximum data for 5 days, and effectively calculates the denominator of "busyness" with the average of these 5 data.
Adopting the average denominator of the maximum number of established sessions in unit time of 5 days, wherein the number of established sessions in unit time and the ratio thereof at present are 'busy';
SMF busy level (average of current number of established sessions per 5 days per maximum number of established sessions) x 100%.
Step S102, after receiving the energy-saving application offline information, the target intelligent energy-saving network element sends energy-saving application response information (with the current busy degree of the target intelligent energy-saving network element) to the first intelligent energy-saving network element.
The energy saving application response information includes the following contents:
TABLE 3
And for the first appointment, the target network element judges whether other existing network elements of the same type as the first intelligent energy-saving network element can replace the first intelligent energy-saving network element, if so, the first intelligent energy-saving network element is allowed to be offline, and if not, the corresponding response type is replied according to the judged actual result.
Step S103, the first intelligent energy-saving network element selects the target intelligent energy-saving network element with the highest busy degree as the awakening network element and the unselected target intelligent energy-saving network element as the alternative network element from the target intelligent energy-saving network elements with the response type of agreeing to go off-line in the energy-saving application response information.
When more than one target intelligent energy-saving network element with the highest busy degree is available, the network elements which are selected by other offline network elements are preferentially selected.
Step S104, the first intelligent energy-saving network element sends energy-saving off-line application information to the awakening network element and requests the awakening network element to store an awakening rule; and simultaneously, the first intelligent energy-saving network element sends the selected information to the alternative network element.
In this step, the first intelligent energy-saving network element sends the energy-saving offline application information for the second time, and this time is a formal application (the second time), and the application flag is 1.
The selected information includes the following (when applying for reference 3):
| number of bytes | Description of the invention | Value and remark |
| 1 | Application mark | 3: has selected other hosts |
| 6 | MAC address | Selected host MAC address |
| 4 | IP address | Selected host IP address |
TABLE 4
Step S105, the awakening network element sends energy-saving application response information to the first intelligent energy-saving network element, and the awakening information is successfully replied and stored.
And step S2, the first intelligent energy-saving network element logs out of service to the NRF.
The first intelligent energy saving network element deregisters the service to the NRF, here using the 5G standard protocol, see 3GPP TS 23.502 V15.6.0(2019-06), section 4.17.3. The specific process of logout is shown in fig. 8, and this process belongs to the prior art and is not described again. Nrf (network redundancy function) is a network registration function, and is a network element of 5 GC.
Other network elements with direct service relationship can be replaced by other network elements of the same type as the first intelligent energy-saving network element, and 3GPP TS 23.502 V15.6.0(2019-06), section 4.17.4 and section 4.17.5 find out the replaced network elements to contact and work.
And the first intelligent energy-saving network element stores the contacted network element information, stores the offline time and finishes the offline.
And step S3, the awakening network element starts to detect the awakening rule, and awakens the offline first intelligent energy-saving network element when the awakening condition is met.
The wake-up network element wakes up the intelligently closed UPFs in the order or rule (by default every 5 minutes of start-up) according to the stored wake-up rules. Wakeup rule as default rule: and the busy degree is more than 50% and lasts for 1 hour or the busy degree is more than 80% and lasts for 0.5 hour, or the time exceeds 7 am, or the requirement of the stored awakening rule is met, and three times of awakening are started.
The wake-up flow is shown in fig. 10, and specifically includes the following steps:
step S301, the awakening network element detects whether absolute awakening time in the awakening rule is met, and if the absolute awakening time in the awakening rule is met, the step S303 is switched to; if not, go to step S302;
step S302, the awakening network element detects whether the condition in the awakening rule is met, and if so, the step S303 is executed; if not, go back to step S301;
step S303, waking up the network element to wake up three times.
By sending wake-up information to the network card that the network element supports wake-up on the network, network card wake-up software supported by the market, which generally continuously sends the MAC address of the network card. The third awakening is to point the network element to send the first awakening, check whether the awakened network element is started or not within a certain time (5-10 minutes), if the awakened network element is not started, send the second awakening again, check whether the awakened network element is started or not within a certain time (5-10 minutes), and if the awakened network element is not started, send the third awakening again.
The flow of conditional wake-up is shown in fig. 11, and specifically includes the following steps:
step S310, waking up the network element to start timing;
step S311, the network element is awakened to detect whether the busy degree of the network element is larger than a first set threshold value, if so, the process goes to step S312, and if not, the step S310 is restarted;
because the awakening network element has a direct service relationship with the first intelligent energy-saving network element, the busy degree of the awakening network element can basically represent the busy degree of the first intelligent energy-saving network element, for example, the service of the UPF is distributed by the SMF, and if the SMF is busy, the UPF receiving the task is busy.
Step S312, the network element is awakened to judge whether the busy degree of the network element is larger than a second set threshold, if so, the step S314 is carried out, otherwise, the step S313 is started;
step S313, the network element is awakened to judge whether the duration time with the busy degree larger than the first set threshold exceeds a first set time value, if so, the step S315 is carried out, otherwise, the step S311 is restarted;
step S314, awakening the network element to judge whether the duration time with the busy degree larger than a second set threshold exceeds a second set time value, if so, turning to step S315, otherwise, restarting step S312;
and S315, after the condition awakening is finished, awakening the network element to awaken the first intelligent energy-saving network element for three times.
The first setting threshold, the second setting threshold, the first setting time value, and the second setting time value in the present invention may be set or modified according to actual situations, for example, the first setting threshold is set to 50%, the second setting threshold is set to 80%, the first setting time value is set to 1 hour, and the second setting time value is set to 0.5 hour. Generally, the first set threshold is smaller than the second set threshold, and the first set time value is greater than the second set time value.

TABLE 5
The key point of the method is that a first intelligent energy-saving network element (UPF network element) judges the load condition to judge whether to close the first intelligent energy-saving network element, and the first intelligent energy-saving network element is awakened through other types of network element equipment (SMF) networks which have direct service relation with the first intelligent energy-saving network element.
The network element judges the load condition by itself, and because the network element can know the change of the real load more easily and does not need to collect the load conditions of other network elements in a complex way, the network element is easier to deploy and more easy to add or remove in a 5G distributed management environment, and the deployment influence on other network elements is reduced.
The difference between the awakening by other types of network element devices and the independent UPF intelligent energy-saving networking is that the SMF can sense the existence of other non-energy-saving UPFs, can close all the UPFs which support energy saving intelligently and save energy when in idle, and enables the non-energy-saving UPFs to continue working. Therefore, even if only one UPF intelligent energy-saving supporting energy-saving exists in one area, the energy can be automatically saved as long as the SMF intelligent energy-saving supporting energy-saving exists. Meanwhile, whether the UPF is started or not is judged by increasing the busy degree of the SMF on the assumption that the busy degree of the SMF and the change of the busy degree of the UPF are basically consistent in one day.
These all make in the heterogeneous environment of 5G decentralized management, make dynamic energy-conserving become possible, intelligent energy-conserving network element can convenient dynamic network deployment.
The invention is suitable for all network elements of 5G, and is also suitable for network elements of 4G and 3G.
The above description is for the purpose of illustrating embodiments of the invention and is not intended to limit the invention, and it will be apparent to those skilled in the art that any modification, equivalent replacement, or improvement made without departing from the spirit and principle of the invention shall fall within the protection scope of the invention.
