Description

Method and system for monitoring link quality between HNB (home node B) and HNB GW (home node B gateway)

Technical Field

The invention relates to a link quality monitoring technology in the communication field, in particular to a monitoring technology of link quality between HNB (home base station) and HNB GW (home base station gateway).

Background

The 3G (third generation mobile communication) system can provide high-speed data service for users, but the 3G system works in the 2GHz frequency band, the wireless signal attenuation is fast, and the building penetration characteristic is poor. Statistically, 70% of data traffic occurs indoors, and thus solving the indoor coverage problem is an important part of completing the construction of 3G networks. The HNB solution is the better solution to the indoor coverage problem. An HNB (Home NodeB, Home base station) is designed for Home communication characteristics, and is an indoor-oriented communication base station with extremely low transmission power, and a user can purchase and install the HNB at will, and generally places the HNB in a Home or an office of the user to provide a wireless access service for the user. The HNB extends the indoor coverage of wireless signals at a lower cost, meets the requirement of users for high-speed data services indoors, and can comprehensively provide various traditional fixed network services (such as broadband internet access services and fixed voice services).

The HNB solution may transmit voice and data calls made by a UE (User Equipment) to a 3G core network; meanwhile, the HNB can be connected to any existing IP (Internet protocol) based transmission network, and the convergence of a fixed network and a mobile network is promoted. As shown in fig. 1, the system architecture of a typical home base station is schematically illustrated, and the system architecture is composed of a UE, a HNB GW (home nodeb Gateway), and a 3G core network. The HNB provides wireless access service for subordinate UE, so that the UE can realize functions of voice call, Internet access and the like; HNB and HNB GW are connected through IP transmission network; the 3G core network is based on a standard interface, and the HNB GW is connected with the 3G core network through the standard interface.

The HNB needs to connect to the HNB GW through the IP transport network and then to the 3G core network. The IP transmission network and the HNB and HNB GW belong to different operators, generally, the IP transmission network belongs to a fixed network operator, and the HNB and HNB GW belong to a mobile network operator, so when data is transmitted and received between the HNB and HNB GW across operator domains, the link quality between the HNB and HNB GW needs to be monitored, so that when network problems such as poor communication or communication quality degradation occur, whether the cause of the network problem is a link failure is located.

The prior art discloses a method for monitoring adjacent Access networks and links between the adjacent Access networks, wherein, a current AN (Access Network ) sends a session information request of UATI (Access terminal identification) to the adjacent AN, and starts a waiting timer; if the current AN does not receive the response message of the adjacent AN within the fixed time of the waiting timer, reporting the hardware fault or the link fault of the adjacent AN, and ending the process; if the current AN receives the response message of the adjacent AN within the fixed time of the waiting timer, the waiting timer is stopped, further if the message type of the response message of the adjacent AN is the session information response, the process is ended, if the message type of the response message of the adjacent AN is the session information rejection, and the rejection reason is determined to be that the requested session is not found according to the rejection reason value, the software fault of the adjacent AN is reported, and the process is ended. The scheme adopts an active detection mechanism, namely, one end of the network actively sends a detection data packet to the opposite end, and the running state of the network is judged according to a detection result returned by the detection data packet. The scheme can not effectively monitor the link quality and then can not accurately position whether the cause of the network problem is the link fault, and when the network flow is larger or a large amount of burst data exists, network congestion is aggravated, so that the link quality is further reduced.

In the prior art, a method for monitoring network performance between network elements is disclosed, wherein network management equipment issues a corresponding relation between an opposite terminal network element and a plurality of IP addresses of the opposite terminal network element to a local terminal network element; according to the corresponding relation, the local terminal network element respectively calculates performance parameters between the local terminal IP address and a plurality of IP addresses of the opposite terminal; the local terminal network element counts a plurality of calculated performance parameters; the local network element reports the statistical performance parameters to the network management equipment; and the network management equipment monitors whether a network problem exists according to the performance parameters obtained from the local network element. The scheme can only monitor whether the network problem exists or not, but can not monitor the link quality and further can not locate whether the generation reason of the network problem is the link fault or not. In addition, in the scheme, the performance parameters between the local terminal IP address and the multiple IP addresses of the opposite terminal are calculated by using the local terminal Network element, and then the statistical performance parameters are reported to the Network management system, which requires that the Network element can calculate and count a large number of performance parameters, and is not suitable for monitoring the link quality between the HNB and the HNB GW.

Detailed Description

The embodiment of the invention provides a monitoring scheme of link quality between HNB and HNB GW, which comprises the steps of respectively carrying out simultaneous statistics and report on parameter values of the same link quality information of two sides of a link, namely an HNB side and an HNB GW side, by introducing a network Management device HMS (Home node B Management System) of the HNB and a network Management device HGWMS (Home node B Gateway Management System) of the HNB, comparing the parameter values reported by the HMS and the HNB GW, and determining the link quality between the HNB and the HNB GW according to the comparison result.

Since the data for monitoring the link quality in the embodiment of the present invention is derived from two network management devices, an HMS and an HGWMS, the structures of the HMS and the HGWMS are briefly described first. As shown in fig. 2, the HMS and the HGWMS may both adopt a hierarchical structure of an existing network management device, and sequentially include, from bottom to top, a data acquisition layer, a management application layer, and a presentation layer. The data acquisition layer is responsible for acquiring data of network element equipment in a managed network, and the data acquisition is generally realized by an adapter; the management application layer is responsible for realizing various management functions, such as configuration management, resource management, performance management, fault management, safety management, topology management, system management and other management functions; the presentation layer is responsible for implementing a human-computer interaction interface. In the embodiment of the invention, the difference between the HMS and the HGWMS is only that the network element device managed by the HMS is HNB and the network element device managed by the HGWMS is HNB GW.

The following describes in detail a scheme for monitoring link quality between the HNB and the HNB GW with reference to the drawings in the specification.

The embodiment of the invention provides a method for monitoring the link quality between HNB and HNB GW, as shown in figure 3, comprising the following steps:

s301, HMS counts and reports a first parameter value of the link quality information on the HNB side of the link to be monitored, and HGWMS counts and reports a second parameter value of the same link quality information on the HNB GW side of the link to be monitored;

s302, the link quality monitoring equipment compares a first parameter value and a second parameter value of the received link quality information, and determines the link quality between HNB and HNB GW according to the comparison result.

It should be noted that the parameter values of the same link quality information reported by the HMS and the HGWMS are counted with the granularity of the Iuh interface established when the HNB and the HNB GW communicate. The Iuh interface is established when HNB communicates with HNB GW, one HNB can establish a plurality of Iuh interfaces with a plurality of HNB GW, and one HNB GW can also establish a plurality of Iuh interfaces with a plurality of HNB GW. Therefore, the HMS and the HGWMS need to count and report parameter values of the same link quality information on both sides (HNB side and HNB GW side) of the link to be monitored with the Iuh interface as the granularity.

The HMS and the HGWMS respectively count a large amount of link quality information on the HNB side and the HNB GW side, and the modes for reporting the link quality information by the HMS and the HGWMS include, but are not limited to, the following:

the method comprises the steps that a same statistical period is configured for an HMS and an HGWMS in advance, the HMS and the HGWMS report a first parameter value and a second parameter value of the statistical link quality information periodically, and the statistical period can be configured flexibly, for example, 15 minutes, 1 hour, 1 day and the like;

in the second mode, the link quality monitoring equipment simultaneously sends an extraction request of the link quality information to the HMS and the HGWMS, and the HMS and the HGWMS report a first parameter value and a second parameter value of the link quality information which are counted according to the received extraction request;

and thirdly, introducing a first parameter value and a second parameter value of the link quality information counted by the HMS and the HGWMS into the link quality monitoring equipment in a manual mode.

The link quality information of the HNB side and the HNB GW side may be functionally divided into control plane information and user plane information, where the control plane information specifically may include:

HNB registration request times, HNB registration success times, HNB registration failure times, UE registration request times, UE registration success times, UE registration failure times, circuit domain RAB (Radio access bearer) assignment request times, circuit domain RAB assignment response times, packet domain RAB assignment request times, packet domain RAB assignment response times, circuit domain RAB connection average establishment time, circuit domain RAB connection maximum establishment time, packet domain RAB connection average establishment time, packet domain RAB connection maximum establishment time, uplink RUA (Remote User Agent) signaling packet numbers, downlink RUA signaling packet numbers, and the like.

The user plane information may specifically include:

the number of circuit domain user plane uplink data packets, the number of circuit domain user plane downlink data packets, the number of packet domain user plane uplink data packets, the number of packet domain user plane downlink data packets, and the like.

The following describes the scheme provided by the embodiment of the present invention in detail, respectively, with respect to various specific link quality information.

Example one

In this embodiment, for link quality information sent from the HNB to the HNB GW, if a link fails (for example, a data packet is intercepted by an IP transport network), the HMS and the HGWMS respectively count that parameter values on the HNB side and the HNB GW side have a larger difference for the same link quality information, and on the premise that no statistical error occurs, the parameter value on the HNB side is larger than the parameter value on the HNB GW side, and the specific link quality information includes one of the following contents: HNB registration request times, UE registration request times, uplink RUA signaling packet number, circuit domain RAB assignment response times, packet domain RAB assignment response times, circuit domain user plane uplink data packet number and packet domain user plane uplink data packet number. Assuming that the same statistical period is configured for the HMS and the HGWMS in advance, the method for monitoring the link quality between the HMS and the HGWMS, as shown in fig. 4, includes the following steps:

s401, at the end time of the statistical period, reporting a first parameter value of link quality information on the HNB side of the link to be monitored by the HMS, and reporting a second parameter value of the same link quality information on the HNB GW side of the link to be monitored by the HGWMS;

s402, the link quality monitoring equipment determines the difference value of the first parameter value minus the second parameter value of the link quality information;

s403, judging whether the difference value obtained by subtracting the second parameter value from the first parameter value is greater than or equal to zero, if so, confirming that no statistical error occurs in the comparison result, and continuing to execute S404, otherwise, confirming that the statistical error occurs in the comparison result, and ending the process;

s404, judging whether the comparison result meets a preset link fault judgment condition, namely whether the difference is larger than the product of the first parameter value and a set first threshold value, if so, executing S405, and if not, executing S406, wherein the first threshold value is larger than 0 and smaller than 1 and is generally expressed in a percentage form;

s405, determining a link fault between the HNB and the HNB GW;

the fault reason can be analyzed and stored as the data packet from HNB to HNB GW is intercepted, and the fault reason is displayed to the user;

s406, determining that the link between the HNB and the HNB GW is normal.

Of course, in this embodiment, S404 may also determine whether the comparison result meets a preset link normality determination condition, that is, whether the difference is smaller than or equal to the product of the first parameter value and the set first threshold, if yes, it is determined that the link between the HNB and the HNB GW is normal, otherwise, it is determined that the link between the HNB and the HNB GW is failed.

For example, assuming that the HMS uses the Iuh interface as a granularity to count the registration request times sent by a certain HNB in a period of time as R1, and the HGWMS uses the Iuh interface as a granularity to count the registration request times received by the HNB GW in the same period of time as R2, and the difference between the registration request times of the HNBs on both sides of the link is Rd ═ R1-R2, and the first threshold is set to be 10%, the following determination may be made according to Rd:

when Rd < 0, a statistical error (HMS or HGWMS statistical error) occurred;

when Rd is more than or equal to 0 and less than or equal to R1 x 10%, determining that a link between HNB and HNB GW is normal;

and when the Rd is more than R1 by 10%, determining that the link between the HNB and the HNB GW fails, and considering that the situation that data packets from the HNB to the HNB GW are intercepted possibly exists in the link.

Example two

In this embodiment, for link quality information sent from the HNB GW to the HNB, if a link fails (for example, a data packet is intercepted by an IP transport network), the HMS and the HGWMS respectively count that parameter values on the HNB side and the HNB GW side have a larger difference for the same link quality information, and on the premise that no statistical error occurs, the parameter value on the HNB side is smaller than the parameter value on the HNB GW side, and the specific link quality information includes one of the following contents: the downlink RUA signaling packet number, the circuit domain RAB assignment request times, the packet domain RAB assignment request times, the circuit domain user plane downlink data packet number and the packet domain user plane downlink data packet number. The method for monitoring the link quality between the HMS and the HGWMS, as shown in fig. 5, includes the following steps:

s501, the link quality monitoring equipment simultaneously sends a link quality information extraction request to the HMS and the HGWMS;

s502, according to the received extraction request, the HMS reports a first parameter value of the side link quality information of the HNB of the link to be monitored, and the HGWMS reports a second parameter value of the side link quality information of the HNB GW of the link to be monitored;

s503, the link quality monitoring equipment determines the difference value of the first parameter value minus the second parameter value of the link quality information;

s504, judging whether the difference value of the first parameter value minus the second parameter value is less than or equal to zero, if so, confirming that no statistical error occurs in the comparison result, and continuing to execute S505, otherwise, confirming that the statistical error occurs in the comparison result, and ending the process;

s505, judging whether the comparison result meets a preset link fault judgment condition, namely whether the absolute value of the difference is larger than the product of a second parameter value and a set second threshold value, if so, executing S506, and if not, executing S507, wherein the second threshold value is larger than 0 and smaller than 1 and is generally expressed in a percentage form;

s506, determining the link fault between the HNB and the HNB GW;

the fault reason can be analyzed because the data packet from HNB GW to HNB is intercepted, and the fault reason is shown to the user;

s507, determining that the link between the HNB and the HNB GW is normal.

Of course, in this embodiment, S505 may also determine whether the comparison result meets a preset link normality determination condition, that is, whether the absolute value of the difference is smaller than or equal to the product of the second parameter value and the set second threshold, if yes, it is determined that the link between the HNB and the HNB GW is normal, otherwise, it is determined that the link between the HNB and the HNB GW is failed.

For example, suppose that the HMS counts the number of downlink packets of the user plane of the circuit domain in a period of time to be R1, and the HGWMS counts the number of downlink packets of the user plane of the circuit domain in the same period of time to be R2. The difference between the numbers of the downlink data packets of the circuit switched domain user plane on both sides of the link is Rd ═ R1-R2, the second threshold is set to be 10%, and the Rd can be determined as follows:

when Rd > 0, a statistical error (HMS or HGWMS statistical error) occurred;

when the absolute value of the Rd is more than or equal to 0 and less than or equal to R2 by 10%, determining that the link between the HNB and the HNB GW is normal, wherein the absolute value of the Rd is represented by the absolute value of the Rd;

when | Rd | > R2 × 10%, determining that the link between the HNB and the HNB GW fails, and considering that a situation that data packets from the HNB GW to the HNB are intercepted possibly exists in the link.

It should be noted that the present embodiment is also applicable to the average establishment time of the RAB connection in the circuit domain/packet domain counted by the HMS and the HGWMS respectively. If the link fails (for example, the data packet is abnormally delayed), the parameter values of the HNB side and the HNB GW side respectively counted by the HMS and the HGWMS for the same link quality information have a larger difference, and the parameter value of the HNB side is larger than the parameter value of the HNB GW side on the premise that no statistical error occurs.

For example, suppose that the HMS counts the average establishment time of the RAB connection in the circuit domain within a period of time to be R1, and the HNB GW counts the average establishment time of the RAB connection in the circuit domain within the same period of time to be R2. The difference between the average setup times of RAB connections in circuit domains on both sides of the link is Rd R1-R2, where R2R 1+ the bidirectional delay of the IP transport network, the second threshold is set to 20%, and Rd may be determined as follows:

when Rd > 0, a statistical error (HMS or HGWMS statistical error) occurred;

when the absolute Rd absolute is more than or equal to 0 and less than or equal to R2 by 20%, determining that the link between the HNB and the HNB GW is normal;

when | Rd | > R2 × 20%, determining that the link between the HNB and the HNB GW is failed, and considering that there may be a case where a packet between the HNB and the HNB GW is abnormally delayed in the link.

It should be noted that, in both the first embodiment and the second embodiment, the difference between the first parameter value at the HNB side and the second parameter value at the HNB GW side is determined first, and then the link quality between the HNB and the HNBGW is determined according to the difference, which is easy for a person skilled in the art to know how to determine the link quality between the HNB and the HNB GW according to the difference between the second parameter value at the HNB GW side and the first parameter value at the HNB side, and details are not described in the embodiment of the present invention again.

EXAMPLE III

In this embodiment, the link quality monitoring device first determines success rates of corresponding link quality indexes at the HNB side and the HNB GW side, respectively, according to parameter values of the HNB side and the HNB GW side, which are respectively counted by the HMS and the HGWMS for the same link quality information, and then determines a difference between the success rates at the HNB side and the HNB GW side. Specifically, the method comprises the following steps:

the link quality information comprises HNB registration success frequency Rs and HNB registration request frequency Rt, and the corresponding link quality index is HNB registration success rate

Or, the link quality information includes UE registration success frequency Rs and UE registration request frequency Rt, and the corresponding link quality index is the UE registration success rate

If the link fails (for example, a data packet is intercepted by an IP transmission network), the success rates of the corresponding link quality indexes respectively determined by the HMS and the HGWMS for the same link quality information at the HNB side and the HNBGW side have a larger difference, and the success rate at the HNB side is smaller than the success rate at the HNB GW side on the premise that no statistical error occurs. Assuming that the same statistical period is configured for the HMS and the HGWMS in advance, the method for monitoring the link quality between the HMS and the HGWMS, as shown in fig. 6, includes the following steps:

s601, at the end time of the statistical period, reporting a first parameter value of link quality information on the HNB side of the link to be monitored by the HMS, and reporting a second parameter value of the same link quality information on the HNB GW side of the link to be monitored by the HGWMS;

s602, the link quality monitoring equipment determines a first power forming rate of a link quality index corresponding to the HNB side according to a first parameter value of the link quality information, and determines a second power forming rate of the same link quality index on the HNB GW side according to a second parameter value of the link quality information;

s603, determining a difference value of the first power forming rate minus the second power forming rate of the link quality index;

s604, judging whether the difference value of the first power forming power minus the second power forming power is less than or equal to zero, if so, confirming that no statistical error occurs in the comparison result, and continuing to execute S605, otherwise, confirming that the statistical error occurs in the comparison result, and ending the process;

s605, judging whether the comparison result meets a preset link fault judgment condition, namely whether the absolute value of the difference is greater than a third threshold value, if so, executing S606, otherwise, executing S607, wherein the third threshold value is greater than 0 and less than 1 and is generally expressed in percentage;

s606, determining a link fault between the HNB and the HNB GW;

s607, determining that the link between the HNB and the HNB GW is normal.

Of course, in this embodiment, S605 may also determine whether the comparison result meets a preset link normality determination condition, that is, whether the absolute value of the difference is smaller than or equal to a set third threshold, if yes, it is determined that the link between the HNB and the HNB GW is normal, otherwise, it is determined that the link between the HNB and the HNB GW is failed.

For example, since the IP transport network intercepts the HNB registration request message, so that the HNB registration request number received by the HNB GW is less than the registration request number sent by the HNB, the HMS may count a value lower than the HGWMS for the HNB registration success rate in the same time period. Assuming that the HNB registration success rate counted by the HMS is P1 and the HNB registration success rate counted by the HGWMS is P2, the difference Pd between the HNB registration success rates on both sides of the link is P1-P2, and the third threshold is set to 10%, Pd may be determined as follows:

when Pd > 0, a statistical error (HMS or HGWMS statistical error) has occurred;

when the | Rd | is more than or equal to 0 and less than or equal to 10 percent, determining that the link between the HNB and the HNB GW is normal;

and when the | Rd | is more than 10%, determining that the link between the HNB and the HNB GW fails, and considering that the data packet from the HNB to the HNB GW can be intercepted in the link.

Example four

the link quality information comprises circuit domain RAB assignment response times Rs and circuit domain RAB assignment request times Rt, and the corresponding link quality index is circuit domain RAB assignment response success rate

Alternatively, link quality packetsIncluding group domain RAB assignment response times Rs and group domain RAB assignment request times Rt, the corresponding link quality index is group domain RAB assignment response success rate

If the link fails (for example, a data packet is intercepted by an IP transmission network), the success rates of the corresponding link quality indexes respectively determined by the HMS and the HGWMS for the same link quality information at the HNB side and the HNBGW side have a larger difference, and the success rate at the HNB side is greater than the success rate at the HNB GW side on the premise that no statistical error occurs. As shown in fig. 7, the method comprises the following steps:

s701, the link quality monitoring equipment simultaneously sends a link quality information extraction request to the HMS and the HGWMS;

s702, according to the received extraction request, reporting a first parameter value of the side link quality information of the HNB of the link to be monitored by the HMS, and reporting a second parameter value of the side link quality information of the HNB GW of the link to be monitored by the HGWMS;

s703, the link quality monitoring equipment determines a first power forming rate of a link quality index corresponding to the HNB side according to a first parameter value of the link quality information, and determines a second power forming rate of the same link quality index at the HNB GW side according to a second parameter value of the link quality information;

s704, determining a difference value of the first power forming rate minus the second power forming rate of the link quality index;

s705, judging whether the difference value of the first power forming rate minus the second power forming rate is larger than or equal to zero, if so, confirming that no statistical error occurs in the comparison result, and continuing to execute S706, otherwise, confirming that the statistical error occurs in the comparison result, and ending the process;

s706, determining whether the comparison result meets a preset link failure determination condition, that is, whether the difference is greater than a set fourth threshold, if yes, executing S707, and if not, executing S708, wherein the fourth threshold is greater than 0 and less than 1, and is generally expressed in percentage;

s707, determining a link fault between the HNB and the HNB GW;

the fault reason can be analyzed because the data packet from HNB to HNB GW is intercepted, and the fault reason is shown to the user;

and S708, determining that the link between the HNB and the HNB GW is normal.

Of course, in this embodiment, S706 may also determine whether the comparison result meets a preset link normality determination condition, that is, whether the difference is smaller than or equal to a set fourth threshold, if yes, it is determined that the link between the HNB and the HNB GW is normal, otherwise, it is determined that the link between the HNB and the HNB GW is failed.

For example, since the IP transport network intercepts the circuit domain RAB assignment response message, so that the frequency of the circuit domain RAB assignment response received by the HNB GW is less than the frequency of the circuit domain RAB assignment response sent by the HNB, the calculated value of the HMS is higher than the calculated value of the HGWMS for the RAB assignment response success rate of the HNB in the same time period. Assuming that the RAB assignment response success rate counted by the HMS is P1 and the RAB assignment response success rate counted by the HGWMS is P2, the difference Pd between the RAB assignment response success rates on both sides of the link is P1-P2, and a fourth threshold is set to 10%, where Pd may be determined as follows:

when Pd < 0, a statistical error (HMS or HGWMS statistical error) occurred;

when Rd is more than or equal to 0 and less than or equal to 10 percent, determining that the link between HNB and HNB GW is normal;

and when the Rd is more than 10%, determining that the link between the HNB and the HNB GW fails, and considering that the data packet from the HNB to the HNB GW can be intercepted in the link.
