Description
Technical field
The present invention relates to wireless isomer communications net, specifically, it relates to for optimizing the method for wireless link bezel mouth parameter in cordless communication network.
Background technology
Heterogeneous network (HeterogeneousNetwork:HetNet) movability discussing LTE in 3GPP is improved. The handoff technique of the user equipment of high-speed mobile is the difficult point in HetNet technology. In RAN2 heterogeneous network movability is improved, the Radio Link Failure (RadioLinkFailure:RLF) caused by heterogeneous network movability is the important subject in RAN2. Can finding out from emulation, it is excessively little that the performance of handoffs of the user equipment of high-speed mobile worsens mainly coverage due to " low transmission power node ". The such handoff failure of major part finally causes Radio Link Failure. Due to the expense relatively big (even if may recover, big interruption of service will be caused) of Radio Link Failure, it is therefore desirable for reduce the probability that Radio Link Failure occurs further, total and in the interruption of service time occurring to reduce during Radio Link Failure.
The setting of wireless link bezel mouth parameter is depended in the RLF judgement of user equipment to a great extent. In traditional macrocell system, user equipment performs channel quality instruction (ChannelQualityIndicator:CQI) measurement and monitors for wireless link. If broadband CQI average for a long time is lower than predetermined threshold value, wireless link monitoring window (being presented as parameter T310 in current standard) will be triggered, and start timing, this represent radio link conditions poor. Therefore, the measurement report of user equipment and/or the transmission of switching order will be highly susceptible to failure and cause handoff failure. Before T310 expires, will again attempt measurement report and switching order. If the average broadband CQI measurement of wireless link monitoring is greater than another predetermined threshold before T310 expires, user equipment will stop the timing of T310, and by its set back to zero, thinks that wireless link recovers at this.If until T310 expires, the measuring result of wireless link monitoring does not exceed another predetermined threshold yet, then user equipment report Radio Link Failure.
The setting of T310 is in fact for determining the Radio Link Failure that wireless coverage blind spot causes. During traditional T310 is arranged, base station is only user equipment and is equipped with a T310 value. But, in heterogeneous network, owing to introducing small cell, such as Microcell (PicoCell) and home cell (FemtoCell) are to reduce the load of grand community, or strengthen the covering of grand community at the edge of grand community, the situation of network is more complicated.

Embodiment
In the specific descriptions of following preferred embodiment, with reference to forming the accompanying drawing appended by a part of the present invention. Appended accompanying drawing shows the specific embodiment that can realize the present invention by way of example. The embodiment of example is not intended to limit according to all embodiments of the present invention. It can be appreciated that under the prerequisite of scope not deviateing the present invention, it is possible to use other embodiments, it is also possible to carry out the amendment of structure or logicality. Therefore, following specific descriptions are not restrictive, and the scope of the present invention is limited by appended claim.
The network that Fig. 1 shows heterogeneous wireless communication net opens up benefit figure. In the embodiment shown in fig. 1, be implemented as Microcell with small cell, those skilled in the art it is understood that, small cell can also be home cell.
Heterogeneous wireless communication net 100 comprises grand community 110 and Microcell 120 and is connected to the user equipment 130 of grand community 110 as shown in Figure 1. Microcell 120 in different network forming for reducing the load of grand community 110, and it is possible that Microcell 120 to be arranged on the edge of grand community 110, to strengthen the covering of grand community 110. But, emulation result shows, the user equipment of high-speed motion is occurring the probability of Radio Link Failure higher through Microcell.
Such as, in the embodiment shown in fig. 1, user equipment 130 moves through Microcell 120 along dotted line with the direction from A to D. Wherein A point represents that user equipment 130 finds the position of Microcell, and B point represents the position in Microcell, and C point represents the edge of Microcell, and D point represents the position that user equipment is connected with grand cell recovery.
According to embodiments of the invention, in the different movability scenes in different network forming, user equipment adopts different wireless link bezel mouth parameters. In the following description, wireless link bezel mouth parametric representation is T310.
Below for such user equipment motion route, different movability scenes is introduced:
Scene 1: grand community to grand community
In normal scene, user equipment is connected with grand community, and predicts not switching or only predict grand in grand switching, adopts and traditional only comprises the normal T310 value in macrocell system.
Scene 2: grand community is to Microcell
(1) user equipment of high-speed motion is not allowed to switch to the situation of Microcell
The user equipment 130 being connected to grand community enters Microcell, and such as, at B point, if not switching to Microcell, it then will suffer the interference from Microcell, and user equipment 130 will suffer RLF and may trigger process of establishing again. First user equipment is selected carrying out to find suitable community community. In this case, because Microcell 120 signal is relatively strong likely selects Microcell 120. And owing to user equipment 130 moves just fast, during random access procedure, probably just move to the edge of Microcell 120, such as C point. User equipment 130 disconnects with the connection of grand community, and wireless heterogeneous networks (RRC) connection reconstruction process will failure.User equipment 130 reenters grand community subsequently, and reconnects in D Dian Yuhong community.
Therefore, according to one embodiment of the present of invention, for this kind of situation, wireless link bezel mouth parameter is expanded to bigger value, to ensure that user equipment 130 and grand community 110 keep being connected.
(2) user equipment of high-speed motion is allowed to switch to the situation of Microcell
(2.a) success of user equipment incision Microcell, cuts out failure
If user equipment can switch to Microcell, and has switched, user equipment is by the connection of release with grand community. Therefore do not re-use the T310 of grand community, and the T310 of Microcell configuration may be received. When user equipment cuts out to grand community from Microcell, know that the probability of handoff failure is very high based on emulation result. If handoff failure, unlikely recover the wireless connections with Microcell, then needs are accessed as early as possible again grand community. Therefore, in this case, after user equipment successfully switches to Microcell, T310 should be established back short value.
(2.b) failure of user equipment incision Microcell, leaves covering region, Microcell subsequently
In this case, user equipment 130 speed is higher, probably through Microcell 120 within the very short time. When user equipment 130 moves in Microcell 120, such as, at B point, it will suffer the interference from Microcell 120, and causes the failure of incision Microcell 120.
In this case, according to one embodiment of the present of invention, adopting longer T310 value as wireless link bezel mouth parameter, if user equipment attempts incision Microcell but failure, it may keep connecting in Reng Yuhong community. Even if owing to the interference of Microcell is very poor with the wireless connections of grand community, but RLF also can not be caused before T310 is expired. Before T310 is expired, if user equipment have passed through Microcell, then will recover the wireless connections with grand community, and T310 is set to normal value.
Sight 3 Microcell to grand community
For this kind of situation, according to embodiments of the invention, T310 is set to short value, because the quality of radio connection with Microcell is highly susceptible within the short period of time to be deteriorated, unlikely recover within the short period of time.
Sight 4 Microcell is to Microcell
For this kind of situation, according to embodiments of the invention, T310 is set to short value, because user equipment unlikely returns to the Microcell of original service within the short period of time. Setting should be identical with arranging of Microcell to grand community.

Specifically, in method steps S203, user equipment 120 is by judging whether successfully to recognize Microcell and meets switching condition and judges whether close to described Microcell.
According in one embodiment of the present of invention, judge close to after Microcell 120 at user equipment 130, use the 2nd parameter as wireless link bezel mouth parameter, and in method steps S206, judge whether user equipment 130 has switched to Microcell 120 further. If it is determined that result is yes, then using the 3rd parameter obtained from the base station of described Microcell as wireless link bezel mouth parameter in method steps S209, wherein, described 3rd parameter is less than described first parameter. At this, those skilled in the art it is understood that, microcell base station configures the 3rd wireless link bezel mouth parameter for user equipment 130 in method steps S207, and the base station that the 3rd wireless link bezel mouth parameter is less than described grand community is the first wireless link bezel mouth parameter and the 2nd wireless link bezel mouth parameter of described user device configuration. In method steps S208, the 3rd wireless link bezel mouth parameter is sent to user equipment by microcell base station.
In foundation one embodiment of the present of invention, the 3rd parameter is relevant to the movement velocity of user equipment, and/or the time of recovery interrupting time and Radio Link Failure with the maximum traffic of described user equipment present type of service is relevant. Such as, the movement velocity of user equipment is more high, and the 3rd parameter is more little. Again such as, sum time of recovery of the 3rd parameter and Radio Link Failure is less than or equals the maximum traffic interruption time of permission.
If user equipment does not switch to Microcell 120, such as previously described do not allow the user equipment of high-speed motion from grand cell merge to Microcell, or user equipment is from grand cell merge to Microcell handoff failure, then judge whether described user equipment has left described Microcell at method steps S210 resume. If it is determined that result is yes, then return to method steps S203, continue to use described first parameter as wireless link bezel mouth parameter, and continue to perform step S204; If it is determined that result is no, then continue to use described 2nd parameter as Radio Link Detection window parameter.
Specifically, in method steps S210, judge that the channel quality of grand community indicates whether to be greater than predetermined threshold, if channel quality instruction is more than or equal to predetermined threshold, then determine that user equipment has left picocell coverage area; If channel quality instruction is less than predetermined threshold, then determine that user equipment not yet leaves picocell coverage area.
Fig. 3 shows according to another embodiment of the invention method stream figure. According to, in this embodiment of the present invention, microcell base station and macro cell base station are all above-mentioned three the wireless link bezel mouth parameters of user device configuration. Thus, it is not necessary to distinguish the configuration of wireless link bezel mouth parameter according to the size of community, system configuration is convenient, is easy to the realization of stdn.
Specifically, in method steps S301 and step S307, macro cell base station and microcell base station are above-mentioned three the wireless link bezel mouth parameters of user device configuration, and in step S302 and step S308, grand community and Microcell send above-mentioned three wireless link bezel mouth parameters respectively to user equipment.User equipment 130 is using minimum as the 3rd parameter in three parameters in method steps S303, and maximum one is as the 2nd parameter, and remaining one as the first parameter. The content that embodiment shown in all the other method stepss and composition graphs 2 describes is similar, does not repeat them here. Such as after switching to Microcell 120, user equipment 130 chooses the 3rd minimum parameter as wireless link bezel mouth parameter from three parameters.

Specifically, macro cell base station is only user equipment in method steps S401 and is equipped with the first parameter, and in method steps S402, the first parameter is sent to user equipment 130. If user equipment judges that in method steps S404 user equipment 130 is close to Microcell 120, then send the first request message to macro cell base station in method steps S405. Macro cell base station, after receiving the first request message, is user device configuration the 2nd parameter in method steps S406, and wherein the first parameter is less than described 2nd parameter. And in method steps S407, the 2nd parameter is sent to user equipment subsequently.
Those skilled in the art it is understood that, if user equipment 130 detects that in method steps S409 user equipment does not switch to Microcell, then with Fig. 2 similarly, user equipment 130 judges whether described user equipment has left Microcell further. If it is determined that result is yes, then send the 2nd request message to macro cell base station, to ask macro cell base station to reconfigure Radio Link Detection window parameter as user equipment 130. First parameter, after receiving the 2nd request message, is sent to user equipment 130 by macro cell base station. User equipment 130 returns to method steps S403, and continues to perform step S404. If it is determined that user equipment does not also leave Microcell, then continue to use described 2nd parameter as Radio Link Detection window parameter. Do not repeat them here with similar step in Fig. 2 in embodiment illustrated in fig. 3.
