Description
Technical Field
The present invention relates to the field of communications, and in particular, to a network acceleration method and apparatus based on a wireless cell.
Background
With the development of the smart terminal market represented by smart phones and tablet computers, the load of the existing 2G wireless cellular packet network exceeds 70%, and the requirement of accessing the internet by the smart terminal used by a user cannot be met. In order to increase the speed of a user using an intelligent terminal to surf the internet, the following two common solutions are provided: the first is to accelerate the wireless carrier frequency expansion of the busy hour cell of the existing 2G network, wherein the wireless carrier frequency expansion comprises a newly added carrier frequency, a newly added base station (namely cell splitting) and the like; and the second method is to shunt through a 3G/WLAN network, so that the load of a 2G network is relieved, and the internet access rate of the user intelligent terminal is improved.
The first method for expanding the wireless carrier frequency of the cell in busy time of the 2G network has the following problems that along with the development of the technology, the large-scale 3G/4G network construction is already deployed, and the 2G network belongs to a technology elimination product and is not suitable for expanding the large-scale 2G wireless carrier frequency; moreover, due to the limited radio carrier frequency resources, the single-cell carrier frequency of data hot spots of a part of large cities reaches the limit, and the capacity expansion of the 2G radio carrier frequency cannot be continuously carried out; the data hot spot of the office place and residential area of urban area has the "tide" effect of large-scale flow, the "tide" effect is that the wireless flow of the super busy district of urban area is in idle state to night in daytime, and the residential area becomes super busy district at night, its wireless flow is in idle state too to the daytime, even can arrange the wireless dilatation of 2G district, also there is the problem that the whole utilization ratio of network is not enough, causes the wasting of resources.
In the second method for shunting through the 3G/WLAN network, because the coverage area of the existing 3G/WLAN network still cannot be compared with that of the 2G network, the WLAN network only covers a small number of hot spot areas, a real shunting effect cannot be achieved, and the rigid requirement of surfing the Internet of a large number of 2G terminal users cannot be met in a short period.
Both of the above two acceleration methods cannot adaptively adjust the network acceleration policy according to the real-time network usage status of the user. If a strong network acceleration adjustment is used in some areas, users using the network in the areas are also in a change all the time, and if the number of users in the network is not large, a Packet Data Channel (PDCH) is idle, which results in a decrease in the utilization rate of PDCH resources; if a network with weak strength is used for accelerating adjustment in some areas, when the number of users who surf the internet is increased, part of the users may drop off the internet, and the use of the users is affected.

Detailed Description
In order to provide an implementation scheme that an effective network acceleration strategy can be allocated according to the current network use situation of the area where the user is located, so as to accelerate the speed of the user to surf the internet, embodiments of the present invention provide a network acceleration method and apparatus based on a wireless cell, which can adaptively accelerate according to the actual situation that the area where the user is located uses the network by using different network acceleration strategies, not only improve the internet speed of the user, but also avoid the problem of the reduction of the PDCH resource utilization, and the following description will refer to the preferred embodiment of the present invention in combination with the accompanying drawings of the description.
Referring to fig. 1, the network acceleration method based on the wireless cell specifically includes the following steps:
step 100: an Acceleration Service Node (ASN) network element receives a serving cell identifier of a terminal sent by a Gateway GPRS Support Node (GGSN).
Specifically, the ASN network element in the present invention may appear as an independent network element, or may be installed in other existing network elements, such as a Wireless Access Protocol (WAP) gateway and a CACHE (CACHE) system, to be directly upgraded in function.
The method for receiving the service cell identifier of the terminal sent by the GGSN includes: receiving and responding to a ranging request initiated by the GGSN; and acquiring the service cell identification of the terminal from the ranging request.
A RADIUS protocol interface needs to be configured on the GGSN, and a 2G/3G Mobile phone number (MSISDN) and a serving Cell identifier [ Location Area Code (LAC) + Cell Identifier (CI) ] are newly added to the RADIUS access start message. Enabling the ASN network element to identify the serving cell identity (LAC + CI) of the terminal using the network.
Referring to fig. 2, an ASN network element receives a ranging Request (Radius access start) sent by a GGSN, where the ranging Request is sent to the ASN network element by the GGSN after receiving a Create packet data protocol context Request (Create PDP context Request) sent by a Serving GPRS Support Node (SGSN).
When the position information of the terminal changes, receiving and responding to a ranging updating request initiated by GGSN; and acquiring the updated serving cell identifier of the terminal from the ranging updating request.
Referring to fig. 3, when the location information of the terminal changes, the GGSN sends a serving cell identifier (LAC + CI) after the location of the terminal changes through a ranging update request Radius accounting update message, where the ranging update request is sent to an ASN network element by the GGSN after receiving a packet data protocol context creation request sent by the SGSN. Therefore, when the terminal using the network is in a roaming state, the ASN can acquire the serving cell id of the terminal in real time.
Step 110: the ASN network element obtains the average PDCH multiplexing degree of the service cell in the current detection period from a Base Station Controller (BSC) through the service cell identification of the terminal, and judges the congestion level of the service cell according to the average PDCH multiplexing degree.
Specifically, a File Transfer Protocol (FTP) interface is newly added on the ASN network element, and the 2G cell identifier and the PDCH multiplexing level of the current detection period are transmitted through the FTP interface, where a statistical period is preset, and the current detection period is the statistical period before the current time, for example, after the ASN network element acquires the serving cell identifier of the terminal to be accelerated, the time when the PDCH multiplexing level is acquired from the BSC is 8:00, and the current detection period is 7:00 to 8: 00. Through the service cell identifier of the terminal obtained in step 100, the average PDCH reuse degree of the service cell of the terminal in one statistical period is correspondingly obtained from the BSC, where the average PDCH reuse degree N indicates that N users occupy the same PDCH channel on average in one statistical period.
After the ASN network element obtains the average PDCH reuse degree corresponding to the service cell of the terminal in the current detection period, if the PDCH reuse degree is determined to be greater than or equal to a first set threshold value, the congestion level of the service cell is judged to be serious congestion; or, if the PDCH reuse degree is determined to be less than or equal to a first set threshold and greater than or equal to a second set threshold, the congestion level of the serving cell is determined to be general congestion; or, if the PDCH reuse degree is determined to be smaller than a second set threshold, judging that the congestion level of the service cell is congestion-free; wherein the first set threshold is greater than the second set threshold.
By adopting the method, the average PDCH reuse degree of the service cell of the terminal using the network can be obtained in real time so as to know the current congestion degree of the terminal, and the shorter the preset statistical period is, the stronger the real-time property is.
Further, the BSC may count all 2G cells and corresponding congestion periods in advance, and calculate PDCH reuse degrees of the congestion periods. Generally, when the average PDCH reuse degree of a cell is greater than or equal to 6, the cell is defined as heavily congested; when the average PDCH reuse degree of a cell is less than 6 and greater than or equal to 4, the cell is defined as general congestion; and when the average PDCH reuse degree of the cell is less than 4, the cell is defined as no congestion.
For example, the 2G cell counted in advance and the corresponding congestion period are specifically in the following form.
And the wireless cell 1 (LAC 1+ CI 1) is in a severe congestion period of 10: 00-16: 00, is in a general congestion period of 16: 00-20: 00, and is free of congestion in other periods.
And the wireless cell 2 (LAC 2+ CI 2) is in a severe congestion period of 16: 00-22: 00, is in a general congestion period of 9: 00-16: 00, and is not congested in other periods.
Therefore, if all 2G cells and corresponding congestion periods are counted in advance, after the ASN network element obtains the serving cell identifier of the terminal, the PDCH reuse level of each period counted in advance may be directly obtained from the BSC, and the congestion level of the serving cell of the terminal is determined according to the congestion period at which the current time is located.
The method can accelerate the ASN network element to judge the current congestion level of the service cell of the terminal so as to execute the operation of subsequently distributing the network acceleration strategy.
Step 120: and the ASN network element distributes a network acceleration strategy for the service cell of the terminal according to the congestion level of the service cell.
Specifically, if the congestion level of the serving cell is determined to be serious congestion, a network acceleration strategy with a number greater than or equal to a set number is allocated to the serving cell of the terminal; or, if the congestion level of the service cell is judged to be general congestion, allocating a network acceleration strategy with the number less than the set number to the service cell of the terminal; or, if the congestion level of the serving cell is judged to be congestion-free, allocating a network acceleration strategy with the number of zero for the serving cell of the terminal.
The network acceleration strategies of the ASN network elements adopted in the present invention include the following three types, but are not limited to these three types, and other network acceleration strategies and combinations thereof may also be used:
(1) data compression techniques. The wireless internet access takes the content of a certain website as an example: one common web site includes text, various format pictures, FLASH animation, JAVASCRIPT, etc. The method is characterized in that the website content is classified according to priority, a proper data compression algorithm is selected, for example, picture files are compressed in a certain loss mode, wireless transmission time and required bandwidth can be reduced, and therefore the internet speed is improved by about 20% -30%.
(2) Content caching techniques. The ASN network element caches the website content once accessed on the local server, and when a new user accesses the same content, the new user does not need to obtain the same content from the original website and directly obtains the same content from the website content cached on the local server by the ASN network element, so that the transmission delay of the wired core network side is reduced. The speed of the internet can be generally improved by about 5% -10%.
(3) Protocol optimization techniques. The TCP/IP technology used by common wireless internet access can improve the efficiency of wireless air interface transmission by simplifying signaling control and other modes, and generally can improve the internet access speed by about 5 percent.
The acceleration methods are independent of each other, and can be implemented individually or in combination for a single wireless internet user. The data compression technology solves the problem of prolonging during wireless air interface transmission, namely, in a severely congested cell, the time delay of a user for waiting for webpage loading is improved by reducing the wireless transmission flow of the user, the single user is accelerated best, but when the user is not used properly, the PDCH channel is idle possibly caused, and the resource utilization rate of the PDCH channel is reduced. The content caching technology solves the problem of repeated transmission of core network transmission, has better effect of improving the downloading speed of cross-operator content, and has better integral acceleration effect than the data compression technology because the wired transmission delay of the core network is far lower than the wireless air interface transmission delay, but has no influence on the wireless air interface transmission of a user, so the flow used by the user cannot be reduced, namely the idle of a PDCH channel cannot be caused. The Protocol optimization technology performs Protocol optimization for the transmission characteristics of the TCP/IP technology, reduces the transmission amount of a Transmission Control Protocol (TCP) signaling, can improve the wireless air interface transmission efficiency, but has the worst effect on network acceleration, reduces the traffic used by a user, namely, affects the utilization rate of a PDCH channel, but has very little effect.
Therefore, when the congestion level of the serving cell is determined to be severely congested, the serving cell of the terminal is allocated with the network acceleration strategies greater than or equal to the set number, for example, the set number is three, that is, three network acceleration strategies are used in combination, when the three network acceleration strategies are combined, the actually achievable network acceleration effect exceeds 30%, because the serving cell is a severely congested cell, when the three network acceleration strategies are used in combination, idle of the PDCH channel is still not caused, and because the PDCH channel is not idle, the utilization rate of the PDCH resource is not actually reduced.
If the congestion level of the service cell is judged to be general congestion, allocating a network acceleration strategy with the number less than the set number for the service cell of the terminal; for example, the set number is three, that is, one or two network acceleration policies may be allocated to the serving cell of the terminal, and the two network acceleration policies may be used in combination by arbitrarily selecting two network acceleration policies from the alternative network acceleration policies.
And if the congestion level of the service cell is judged to be congestion-free, distributing a network acceleration strategy with the number of zero for the service cell of the terminal. Namely, the service cell is not accelerated any more, so that the resources of the ASN network element equipment can be saved.
The following illustrates a method and effect of distributing network acceleration policies.
The average PDCH reuse degree of the cell is more than 6, namely at least 6 users occupy the same PDCH channel. The bandwidth of a single PDCH channel is about 42Kbps, the average single channel of 6 users is 7Kbps, and the internet access rate of the single user is obviously reduced. After three network acceleration strategies of data compression, content caching and protocol compression are used, the requirement of single-user data transmission bandwidth is reduced by about 30%, which is equivalent to saving 1.8 user bandwidths, namely 12.6 Kbps. If the number of the PDCH channel access users keeps unchanged at this moment, the bandwidth occupied by the PDCH channel users is the same as the bandwidth occupied by 4.2 users, namely, the speed of a single user is increased to about 10Kbps, and the users can be maintained not to drop in a severely congested cell.
Similarly, for the average PDCH reuse degree of 4, that is, 4 users occupy the same PDCH channel, since the decrease range of the single-user internet rate is not large, the acceleration strategy method may be adjusted, for example, only the content caching and protocol optimization techniques are used, the acceleration effect is about 15% to 20%, the speed of the cell user to access the internet may be further increased, and meanwhile, the PDCH channel is not idle.
The method and effect of distributing the network acceleration strategy in the present invention will be further explained in different specific scenes when the terminal accesses the internet.
User terminal internet scene 1: the cell 1 in the period A is defined as serious congestion, the internet speed of the user is reduced most, at the moment, the network acceleration strategy is a combination form of data compression, data caching and protocol optimization technologies, although the picture quality reduction influence caused by content compression exists, the internet speed of the user is improved best, and the risk of disconnection when the user accesses the internet is reduced;
the purpose of the implementation of scenario 1 is that a wireless cell has severe congestion, which may cause a problem of a drop of a user terminal during internet access. At this time, a network acceleration strategy with the highest compression ratio is adopted, although the traffic used by a single user is reduced, the PDCH can bear more internet access terminals, and the PDCH is still in an idle-free state, so that the utilization rate of the whole resources is not reduced.
User terminal internet scene 2: and the cell 1 in the time interval B is defined as general congestion, and at the moment, the network acceleration strategy can only adopt data caching and protocol optimization, and does not adopt a data compression technology, so that the internet speed of a user is improved by 10-15%.
The implementation of the scenario 2 aims at general congestion of a wireless cell, the user internet access perception is slightly reduced, but the user cannot be interrupted to access the internet, and at the moment, a content caching strategy is adopted, so that the idle of a PDCH channel cannot be caused while the internet access speed is increased by 10% -15% because the wireless air interface flow of the user is not actually reduced. If only protocol optimization is adopted, the single-user flow can be reduced by 5%, the common congestion condition can be properly relieved, and the PDCH reuse degree is not obviously changed.
User terminal internet scene 3: and the cell 1 in the period C is defined as no congestion, and the acceleration service network element adopts a route bypass and does not adopt any network acceleration strategy.
The purpose of the implementation of the scenario 3 is that there is no cell congestion in wireless internet access, the resource load of the ASN network element does not need to be occupied continuously, and the network investment cost of the ASN network element is reduced.
User terminal internet scene 4: and D, when the cell 1 roams to the cell 2, the ASN network element synchronously switches the network acceleration strategy, namely the network acceleration strategy corresponding to the cell 1 is adjusted to the network acceleration strategy corresponding to the cell 2.
The purpose of the implementation of the scenario 4 is to ensure that when a user surfs the internet and roams in different cells, the obvious change of the user internet surfing rate perception is reduced as much as possible.
The above scenarios can be further refined, such as adjustment of the congestion level of the cell in holidays, various combinations of network acceleration strategies, and the like.
