The small packet type service mainly includes small packet service of machine type communication (MTC), and some small data packet services (such as QQ service, WeChat service, etc.) on the mobile terminal. Small packet type service requires a lot of air interface signaling to transmit a data packet due to the small size of the transmitted data packet, which causes excessive signaling overhead. In addition, frequent transmission of small packet-type services can also cause excessive power consumption of mobile terminals. In response to the above two issues, the 3rd Generation Partnership Project (3GPP) provides a variety of solutions during the research phase, but the final solution to the standardization phase only includes the introduction of energy-saving sub-states (for MTC ultra-low power requirements). The long-term standby mode is realized by the energy-saving sub-state, and the long-term connection mode scheme in which the core network provides auxiliary information (the service auxiliary information is provided through the terminal or the network to reasonably configure the network parameters to achieve energy saving and save signaling overhead).

Currently, for a terminal that enters the connected state, the base station has no relevant information to help it configure the network parameters (including the DRX parameter and the connection release timer), so that the base station can only configure the same network parameter for the entire cell instead of According to the specific service characteristics of the terminal, it is difficult to achieve the purpose of saving signaling overhead and reducing terminal power consumption.

The inventor found in the invention that one possible solution to the above technical problem is that the base station counts the service characteristics of each terminal, and then configures the network parameters accordingly. However, the terminal related information is released when the terminal enters the idle state, so that the base station does not have relevant information to configure after the next time the terminal enters the connected state, and only blind configuration can be performed. At the same time, since most of the connection establishment is from the background service or heartbeat packet or service update, the terminal enters the idle state after a short interaction, and the base station can count little information during this time, and cannot count the last connection. The packet delay information established to the next connection is established, so it is difficult to efficiently configure the network parameters according to it.

In view of this, the embodiment of the present invention provides a network parameter acquisition method, which collects service-related auxiliary information by using a UE (terminal) or a base station, and uploads to the MME (Mobile Management Entity) when the connection is released, and the MME itself can also collect certain services.

The arrival time of the packet with the previous packet arrival time interval falling within the range (for example: 15:30:20). In the specific implementation, it is also possible to record the arrival time of all the data packets without dividing the interval until the upper limit of the record is reached.

Preferably, the statistics can be performed in the form shown in Table 2:

Table 2

数据包到达时间间隔区间(s或ms)Packet arrival interval interval (s or ms)	数据包到达时间列表(列表大小N)Packet arrival time list (list size N)

The sixth type information includes: frequency information about occurrence of the adjacent data packet arrival time interval belonging to the data packet arrival time interval interval and time information for updating the occurrence frequency information last time for the data packet arrival time interval interval.

In the specific implementation, the packet arrival time interval may be divided into certain intervals (for example, the standard defines the possible value of the packet arrival interval interval, or the implementation determines how to divide the interval), and records for each interval for a period of time. The frequency at which the packet arrival interval falls within the interval and when the value was last updated. Preferably, the statistics can be performed in the form shown in Table 3:

table 3

数据包到达时间间隔区间(s或ms)Packet arrival interval interval (s or ms)	发生频率(如次数/小时)Frequency of occurrence (eg number of times / hour)	上次更新时间Last update time
数据包到达时间间隔区间(s或ms)Packet arrival interval interval (s or ms)		上次更新时间Last update time	A1～B1A1～B1
A2～B2A2~B2			A1～B1A1～B1
A2～B2A2~B2			…...

Preferably, Table 3 can be updated as follows:

For any packet arrival interval interval, the following method is used to determine the frequency at which the adjacent packet arrival interval in the specified time range belongs to the packet arrival interval interval:

Step 1: For any packet arrival time interval interval, if the arrival time interval of the current data packet and the previous data packet belongs to the data packet arrival time interval interval, determine the arrival time of the current data packet;

Step 2: determining a time when the frequency information corresponding to the interval of the arrival time interval of the data packet is last updated;

Step 3: According to the following formula, the frequency of the arrival time interval of the data packet belongs to the interval of the arrival time interval of the data packet:

The number of times/hour; and determine the frequency of the arrival time interval of adjacent packets within the specified time range belonging to the interval of the packet arrival interval according to the following formula: α*f ₁ +(1 - α)*f ₁ ', where: T The statistical period of the frequency is; t ₁ is the arrival time of the current data packet; t ₂ is the time of updating the frequency information corresponding to the interval of the arrival time interval of the data packet; α is the preset arrival time interval of the current data packet The weight corresponding to the frequency of the packet arrival interval interval; f _{1 is} the frequency at which the packet arrival time interval belongs to the packet arrival interval interval; f ₁ 'is the current recorded packet arrival interval interval The corresponding frequency of occurrence.

For example, taking the statistical period of 1 hour as an example, when the time A (accurate to the second) of a data packet (the packet arrival time interval falls within the interval (A1, B1)) arrives, look at the (A1, B1) interval. The secondary update time is B (accurate to the second), and the packet arrival time interval of this sampling falls within the interval (A1, B1) is 3600/(AB) times/hour; assuming that the weight of this sampling is 0.1, the frequency of occurrence of the packet arrival time interval in the interval (A1, B1) = 0.9 * the frequency of occurrence of the last record + 0.1 * the frequency of occurrence of this calculation.

The seventh type of information includes: a statistical result of the previous statistical period and a statistical data of the current statistical period, wherein the statistical result of the previous statistical period includes the adjacent data recorded in the previous statistical period for the interval of the data packet arrival interval interval. The packet arrival time interval belongs to the frequency of occurrence of the packet arrival interval interval, and the statistics of the current statistical period include records for the packet arrival interval interval, and the adjacent packet arrival time interval belongs to the data packet in the current statistical period. The number of occurrences of the arrival time interval and the start time of the current statistical period.

During the specific implementation, the statistics of the current statistics period may also include the current statistics period information. If not, the statistics are performed according to the default period.

In the specific implementation, statistics can be performed according to the form shown in Table 4. The “Statistic Results of the Last Statistical Period” section on the left side represents the packets that have been counted according to the results of the previous statistical period and fall within the interval of each packet arrival interval. The occurrence frequency of the current statistical period of the current statistical period indicates the cumulative number of occurrences of each packet arrival interval, the current statistical period information, and the current statistical start time.

Table 4

Preferably, the seventh type information can be updated as follows:

After the current statistical period ends, for each preset packet arrival interval interval, the frequency information corresponding to the packet arrival interval interval is updated according to the following formula: β*f ₂ +(1-β)*f ₂ ', where: β is the weight corresponding to the number of occurrences of the adjacent packet arrival time interval in the current statistical period belongs to the packet arrival interval interval; f ₂ is the adjacent packet arrival time interval in the current statistical period belongs to the data packet The number of occurrences of the arrival interval interval; f ₂ 'is the frequency of occurrence of the adjacent packet arrival time interval in the previous statistical period belonging to the arrival interval of the data packet.

Specifically, for any packet arrival time interval interval, the number of occurrences is counted in the current statistical period, and after the current period statistics are completed, the frequency of occurrence in the "statistical result of the previous statistical period" is updated, and the current period is set. The weight of a is the number of occurrences in the frequency = (1-a) * occurrence frequency + a * "statistics of the current statistical period". (It should be noted that if the statistical period does not match the statistical time of the occurrence frequency, a certain conversion is required). Then, the current statistical start time of the "statistics of the current statistical period" is set to the current time, and the number of occurrences is set to zero.

For example, if the set statistics period is 10s, and the terminal and the base station have 5 connection release operations within 10s, the current statistics period data is collected according to Table 4 for each connection release, wherein the number of occurrences is based on each statistics. The cumulative number of occurrences of the results.

S102. The base station configures network parameters for the terminal according to the obtained service-related auxiliary information.

In a specific implementation, the foregoing network parameter may include, but is not limited to, including a DRX (discontinuous reception) parameter. And the connection release timer (the timer), wherein the DRX (discontinuous reception) parameters include drx-InactivityTimer, onDurationTimer, longDRX-Cycle, shortDRX-Cycle, drxShortCycleTimer.

In the specific implementation, for the longDRX-Cycle parameter, the longDRX-Cycle setting should normally meet the longDRX-Cycle<service delay requirement (if there are multiple services, the service delay requirement should take the time delay to require the most demanding service delay requirement. ). However, exceptions can be made for the third type information and the fourth type information.

Preferably, the longDRX-Cycle parameter may be configured in the following manner: the longDRX-Cycle parameter is configured to be smaller than the service delay requirement according to the service delay requirement information; and when the multiple service delay request information is included, The longDRX-Cycle parameter is less than the minimum service delay requirement; or the longDRX-Cycle parameter is configured to be smaller than the minimum value of the arrival time interval of two adjacent data packets according to the third type information; or if the fourth type information is determined to be non-existent according to the fourth type information There is no indication of uplink packet transmission before the downlink data packet is sent, and the time interval between two consecutive downlink data packet transmissions and the time interval between one uplink data packet transmission and the last downlink data packet transmission are smaller than the service delay requirement (or Although greater than the service delay requirement, but much smaller than the connection release timer, the longDRX-Cycle parameter can be configured according to the maximum DRX cycle supported by the standard.

In the specific implementation, the drx-inactivityTimer parameter or the onDurationTimer parameter may be configured according to the burst attribute of the service, and preferably, may be configured according to the burst attribute of the downlink service.

In a specific implementation, the drx-InactivityTimer parameter or the onDurationTimer parameter may be configured in the following manner: according to the first type information, the drx-InactivityTimer parameter or the onDurationTimer parameter is configured to be greater than a maximum value of the arrival time interval of two adjacent data packets. Preferably, Setting onDurationTimer and drx-InactivityTimer is slightly larger than the maximum value of the packet arrival interval in a burst; or

According to the third type information, the drx-InactivityTimer parameter or the onDurationTimer parameter is configured to be larger than the fluctuation range of the arrival time interval of two adjacent data packets. Preferably, the onDurationTimer and the drx-InactivityTimer are slightly larger than the fluctuation range of the packet arrival time interval. Yes; or

According to the fourth type of information, configuring the drx-InactivityTimer parameter or the onDurationTimer parameter is greater than a time interval between one uplink data packet and the last downlink data packet transmission and a maximum time interval between two consecutive downlink data packet transmissions, preferably The onDurationTimer and drx-InactivityTimer can be configured to be slightly larger than the maximum time interval between the transmission of the last uplink data packet and the last downlink data packet transmission and the transmission time interval of the two consecutive downlink data packet transmissions; or

According to the second type information or the fifth type information or the sixth type information or the seventh type information, the drx-InactivityTimer parameter or the onDurationTimer parameter is configured to be greater than a preset data packet arrival time interval, wherein the preset data packet arrival time interval is smaller than longDRX-Cycle. Preferably, the data packet within a certain data packet arrival time interval t (t<longDRX-Cycle) can be classified into a burst, and the onDurationTimer and drx-InactivityTimer parameters are set to be slightly larger than t.

In the specific implementation, the drxShortCycleTimer parameter may be configured according to the first type information, and the drxShortCycleTimer parameter is configured as an average value of the interval between two adjacent bursts in a burst group; or according to the second type information or the fifth type information or For the sixth type information or the seventh type information, the drxShortCycleTimer parameter is configured according to the following method: setting a first burst arrival time interval, the first burst arrival time interval is greater than a preset data packet arrival time interval is less than longDRX-Cycle; determining data The packet arrival interval is the probability between the preset packet arrival interval and the first burst arrival interval; the number of bursts occurring within a longDRX-Cycle is determined according to the following formula:

If n>1, configure the drxShortCycleTimer parameter to be n, where: n indicates the number of bursts occurring within a longDRX-Cycle; p indicates that the packet arrival interval belongs to a preset packet arrival interval and the first burst arrival interval. The probability between times; t ₁ represents the first burst arrival time interval. Among them, the selection of t1 should cover most of the values in the range of [t, longDRX-Cycle], but it should not be too large, so as not to affect the packet transmission delay, where t represents the preset packet arrival time interval.

For specific implementation, the configuration of the shortDRX-Cycle parameter can be divided into the following cases:

For the first type of information, you can configure the shortDRX-Cycle parameter to be the average of the arrival times of two adjacent bursts in a burst group.

For the third type information or the fourth type information, it is not necessary to configure the shortDRX-Cycle parameter;

For the second type information or the fifth type information or the sixth type information or the seventh type information, reference may be made to the manner of configuring the drxShortCycleTime parameter. If n>1, the shortDRX-Cycle is configured, and the shortDRX-Cycle parameter is configured as t ₁ .

In the embodiment of the present invention, the connection release timer is mainly determined according to the third type information/the fifth type information/the sixth type information/the seventh type information. Specifically, the connection may be classified into the following situations:

When it is determined that the terminal is in the connected state, according to the third type information, the configuration connection release timer is greater than the adjacent two data packet arrival time interval information. Preferably, for the third type of information, according to the packet arrival delay and the terminal moving rate, it is determined whether the terminal is in the connected state or the released connection. If the connected state is maintained, the connection release timer should be slightly larger than the maximum packet arrival interval. value.

In a specific implementation, the connection release timer may also be configured according to the fifth type information or the sixth type information or the seventh type information. Preferably, for the sixth type information or the seventh type information, after determining the frequency of occurrence of each arrival time interval interval, it can be known that if the RRC connection release timer is set smaller than the idle state, the idle state is connected to the connection state. The frequency of occurrence (adding all the frequencies of the packet arrival time interval larger than the connection release timer), that is, the length of time that the terminal remains connected, and then knowing the signaling overhead of the handover and the connection state transition of the idle state. The signaling overhead is used to select the appropriate RRC connection to release the timer. For the fifth type information, after the frequency of occurrence of the sixth type information is obtained, the connection release timer can be selected as described in the sixth type information.

In a specific implementation, the service related auxiliary information may be collected by the terminal, or the base station or the MME. The terminal may report and report the service-related auxiliary information except the sixth type information and the seventh type information according to a preset statistical period. If the terminal performs statistics, it can perform statistics when the terminal is in the connected state, or when the terminal is in the idle state. Preferably, the terminal performs statistics on the uplink service and the downlink service separately when performing service related auxiliary information statistics. It is also possible to perform statistics without making a distinction.

Preferably, for the first type of information, the terminal performs the statistics according to the division criterion of the burst and the burst group sent by the MME or according to the division criterion of the burst and the burst group broadcasted by the base station, and the division criterion of the burst and burst groups that may be delivered may be The extent to which the packet arrival interval belongs to a burst, and the burst in which the burst interval is within a large delay range belongs to a burst group, and can also be implemented by the terminal. The allocation criterion of the burst and burst groups is carried in an attach request response message or a TAU (Tracking Area Update) message sent by the MME to the terminal.

In the specific implementation, the service related auxiliary information may be collected by the base station. If the base station performs statistics, the base station can only perform statistics when the terminal is in the connected state, and report the related information to the MME when the connection is released. Specifically, the base station may collect the service-related auxiliary information when the terminal is in the connected state according to the pre-configured statistical period for each terminal, and report the statistical service-related auxiliary to the MME when the connection is released. More preferably, when the connection is released, the base station may also report the connection release timer to the MME.

During the specific implementation, when performing statistics on the service-related auxiliary information, the base station may separately perform statistics on the uplink service and the downlink service, or may perform statistics on the uplink and the downlink.

The following is an example in which the base station determines the time interval between the last data packet establishment and the next data packet connection. Preferably, the base station can determine the last connection establishment in one of the following two manners. The time interval between the packet and the next packet connected:

method one

The base station according to the last arrival of the last connection (uplink/downlink, if the uplink/downlink statistics), and the arrival of the first (uplink/downlink, if the uplink/downlink statistics) packet arrives this time. Time (if the downlink data packet is the time when the base station receives the MME paging time; if it is the uplink data packet, the base station receives the random access preamble time of the UE), to calculate the arrival time interval of the two data packets.

Way two

The base station forms a complete packet arrival time interval information of the terminal service according to the time interval information of the connection release to the connection establishment and the connection release timer value (the last one in the connection establishment) The time interval between the packet and the first packet in the next connection establishment = the time interval at which the connection is released and the connection is released until the connection is established. It should be noted that, if the statistics are performed in the second mode, the time interval between the last data packet in the connection establishment and the first data packet in the next connection establishment can only obtain the mixed service characteristics of the uplink and downlink, and cannot distinguish the uplink and downlink. .

Specifically, for different statistical modes, the base station may determine, according to the following method, a time interval between the last data packet establishment and the next data packet connection: 1) for the uplink service, determine the last uplink of the last connection. The time interval between the arrival time of the data packet and the arrival time of the first uplink data packet of the current connection is the time interval between the last data packet and the first data packet connected for the next connection; 2) for the downlink Service, determining the time interval between the arrival time of the last downlink packet connected last time and the arrival time of the first downlink packet of the current connection is between the last packet establishment and the next data packet connection Time interval; 3) For the uplink and downlink hybrid service, determine the time interval between the arrival time of the last data packet last connection and the arrival time of the first data packet of the current connection, and establish the last data packet and the next connection for one connection. The time interval between the first connection of the first packet.

For the uplink and downlink hybrid service, the base station can also determine the sum of the time interval between the last connection release timer and the last connection release to the current connection establishment. The last data packet is established for one connection and the first data packet is established with the next connection. The time interval between.

It should be noted that, if it is an uplink data packet, the last data packet is a random access preamble moment of the terminal received by the base station, and if it is a downlink data packet, the last data packet is the MME paging time received by the base station.

In a specific implementation, the service-related auxiliary information may also be obtained by the MME, where the MME may automatically calculate the time interval information of the connection release and the next connection establishment, and the remaining information MME may be obtained from the SGW (gateway). Preferably, the MME may perform statistics on the uplink service and the downlink service separately when the time interval information of the connection release and the next connection establishment is calculated, or may perform statistics without distinguishing; the SGW collects statistics in addition to one connection release. When the information other than the time interval information of the connection establishment is used, statistics may be performed separately for the uplink service and the downlink service, or may be performed without distinction.

For a better understanding of the embodiments of the present invention, the following describes the implementation process of the network parameter obtaining method provided by the embodiment of the present invention in conjunction with the process of establishing an RRC connection between the terminal and the base station. As shown in FIG. 2, the terminal establishes an RRC connection with the base station, which may include The following steps:

S201. The terminal establishes an RRC connection with the base station.

The terminal may also provide service related auxiliary information, speed related information (such as cell reselection history information, speed information obtained from a speed measuring module such as GPS, or a rough moving speed estimation of the terminal idle state) when the connection is established.

The service related auxiliary information may be provided by the application layer to the NAS (non-access stratum) layer, or may be self-stated by the NAS layer or the AS (access stratum) layer. If it is counted by the NAS or AS layer, it needs to be counted and updated regardless of whether the terminal is in the idle state or the connected state. Statistics can be counted by business or QCI, or all businesses can be counted together. The uplink or downlink can be divided into statistics, and statistics can also be performed together. In the statistics, after obtaining a certain number of sampling points, the CDF of the delay may be obtained, or the burst and the burst group may be divided according to a certain criterion, and the division criterion may be that the MME allocates the broadcast to the terminal or the base station when the attachment or the TAU is broadcasted (configuration) The content may be a burst in the extent to which the packet arrival interval belongs, and the burst in which the burst interval is within a range of delays belongs to a burst group, or a terminal implementation. After the terminal acquires a certain sampling point again, the statistics can be updated. The update method can be a consolidation by CDF, or a weighted average of new statistics versus old statistics.

S202. The base station sends an initial UE message to the MME.

The MME collects statistics on the time interval of the terminal from the release of one connection to the establishment of the next connection (for example, in the form of a CDF of similar form 2, or recording the last few intervals). During the statistics interval, the MME can combine the reasons for the connection establishment, such as only the connection establishment initiated by the service request, and the connection establishment initiated by the TAU and the connection establishment initiated by the attachment. In addition, the MME may also request the SGW to perform service related auxiliary information statistics for the terminal. The SGW statistics may be configured before the MME, and the SGW performs statistics or obtains from the PGW. The MME may request information from the SGW after receiving the initial UE message of the base station, or after the base station specifically requests the service related auxiliary information from the MME, or the MME may periodically request the SGW, or the SGW periodically (or event triggered) The MME reports.

S203. The MME feeds back an initial context setup request to the base station.

In a specific implementation, the initial context setup request that the MME feeds back to the base station may include a time interval from the release of the primary connection to the establishment of the next connection (if the downlink service triggers the connection establishment, which may be the paging time). Statistics, connection release timer information, service related auxiliary information, user subscription information, and so on.

It should be noted that the connection release timer is maintained by the base station. When the terminal does not send data for a period of time, the timer will time out and the base station releases the UE connection.

S204. The base station appropriately configures network parameters according to the auxiliary information provided by the MME and the UE.

The network parameters include DRX parameters (drx-InactivityTimer, onDurationTimer, longDRX-Cycle, shortDRX-Cycle, drxShortCycleTimer), connection release timer, and the like.

Specifically, there are two statistical methods for the time interval between the last data packet in a connection establishment and the first data packet in the next connection:

1. According to the recorded last arrival (uplink/downlink, if the uplink and downlink statistics are included), the packet arrival time of the data packet, and the arrival of the first (uplink/downlink, incoming and downlink statistics) packets of this connection. Time (if the downlink packet is, the base station receives the MME paging time; if it is the uplink packet, the base station receives the random access preamble time of the UE), to calculate the arrival time interval of the two data packets.

2. According to the time interval statistics released by the connection to the connection establishment, and the connection release timer value, the packet arrival time interval information of a complete terminal service is formed (the last packet in the connection establishment and the first packet in the next connection establishment) Time interval = connection release timer + time interval for connection release to connection establishment). It should be noted that, by the statistic of the method, the time interval between the last packet in the connection establishment and the first packet in the next connection establishment can only obtain the mixed service characteristics of the uplink and downlink, and cannot distinguish between the uplink and the downlink.

If the service-related auxiliary information is directly counted by the UE side or the SGW, the complete packet arrival delay information can be obtained without being combined with the time interval statistics of the connection release to the connection establishment.

S205. After receiving the terminal configuration completion feedback, the base station sends the initial context establishment completion to the MME.

S206. For the connected state terminal, the updated auxiliary information may be provided to the base station at any time, and the base station is also the same The uplink and downlink service characteristics of the terminal during the current connection may be counted, and then the service related auxiliary information is updated.

The statistical method is similar to the statistics of the NAS or the AS in the step S201, and the information is reported to the MME when the connection is released, and the timer information can also be released by the connection. Specifically, it can be piggybacked by a UE CONTEXT RELEASE REQUEST message or a UE CONTEXT RELEASE COMPLETE message. If a handover occurs, the original base station transmits the information to the target base station through the handover request. If it is an S1 handover, it can be provided by the MME to the target base station.
