Description

A kind of Activiation method of backhaul link configuration and equipment

Technical field

The present invention relates to communication technical field, particularly relate to a kind of Activiation method and equipment of backhaul link configuration.

Background technology

LTE (Long Term Evolution, Long Term Evolution) is 3G (3rd Generation, 3-G (Generation Three mobile communication system)) evolution, LTE improves and has strengthened the aerial access technology of 3G, adopt OFDM (Orthogonal Frequency Division Multiplexing, OFDM) and MIMO (Multiple Input Multiple Output, multiple-input and multiple-output) as the sole criterion of wireless network evolution.LTE can provide the peak rate of descending 100Mbit/s and up 50Mbit/s under the 20MHz spectral bandwidth, improved the performance of Cell Edge User, has improved cell capacity, and has reduced system delay.Wherein, the technical characterictic of LTE comprises that high data rate, grouping transmit, hang down delay, wide area covering and backward compatible.Along with increasing rapidly of number of users of mobile terminal amount, terminal use's volume of business is exponential increase, in order to satisfy the terminal use's who continues to increase business demand, the business and the needed more peak value speed of application that need provide bigger bandwidth to satisfy the terminal use.

In the mobile communication system in future, for example among the B3G (Beyond three Generation, back three generations) or in LTE-A (LTE-Advanced, the senior LTE) system, system will provide higher peak data rate and cell throughout, also need bigger bandwidth simultaneously.Unassigned bandwidth below the 2GHz seldom at present, the part or all of bandwidth that B3G system or LTE-A system need can only be on higher frequency range, for example on the frequency range more than the 3GHz, seek, and in the application of reality, frequency range is high more, it is fast more that radio wave propagation is decayed, and transmission range is short more; Therefore, under same overlay area, guarantee continuous covering, then need more base station.

Because the base station has higher cost, when a lot of base station of needs, will increase the cost of creating network.In order to address the above problem, each manufacturer and standardization body are incorporated into relaying (relay) in the cellular system, thereby increase the zone that covers.

As shown in Figure 1, for introducing the network architecture behind the RN (Relay Node, via node) in the LTE-A system.Wherein, RN is linked into core net by the donor cell (alms giver sub-district) under the eNB (Evolved Node B, base station), does not have direct wireline interface between this RN and the core net, and each RN can control one or more sub-districts.Under this network architecture, the interface between UE (User Equipment, subscriber equipment) and the RN is called Uu, and the interface between RN and the DeNB (Donor Evolved Node B, donor base station) is called Un.

In the network architecture shown in Figure 1, RN has dual identity: (1) RN has the identity of UE, and wherein, this RN is similar to the start attaching process of UE when starting.(2) for the UE that inserts RN, RN has the identity of eNB, at this moment, the downlink data of UE need be from the SGW (ServingGateway of UE, gateway)/PGW (Packet Data DomainGateway, the packet data domain gateway) send to the serving BS of UE, i.e. RN, RN sends to UE on the Uu mouth then.

Concrete, in the RN start-up course, may further comprise the steps: set up RRC (Radio Resource Control, Radio Resource control) between (1) RN and the DeNB and connect; (2) RN sends to MME (MobilityManagement Entity, Mobility Management Entity) and adheres to request; (3) MME authenticates RN from the authorization data that HSS (HomeSubscriber Server, home subscriber server) locates to obtain RN; (4) if authentication is passed through, MME for RN sets up default bearing, and sends the initial UE context to DeNB and sets up request message in the DeNB with packet data gateway function, sets up the context of RN in DeNB; (5) DeNB sends RRC to RN and connects reconfiguration message, and this RRC connects and carries MME in reconfiguration message and issue adhering to of RN and accept message; (6) RN returns RRC and connects to reshuffle to finish and confirm.Through above-mentioned steps, RN has then set up basic IP and has connected.Further, (7) O﹠amp; M (Operation and Maintenance, operation and maintenance system) downloads to RN with node configuration information, and RN is configured; (8) RN sets up necessary S1 interface and X2 interface, and at this moment, RN promptly can carry out work to the base station is equally normal; Wherein, the Un mouth becomes one section wireless Backhaullink (back haul link).

Further, after RN was as the base station operate as normal, DeNB may need according to the load condition of the throughput of RN or Un mouth the configuration of descending Backhaul link to be upgraded in subsequent process, promptly Un Backhaul subframe is carried out reprovision; Wherein, this reprovision may be used for the sub-frame number of Backhaul link for change, or the position of subframe.And after Un Backhaul sub-frame configuration changes, RN also needs correspondingly to change the system information of Uu mouth, wherein, if revise MBSFN (Multimedia Broadcast multicast service Single FrequencyNetwork, the multimedia broadcast multi-broadcasting business Single Frequency Network) sub-frame configuration of Uu port system information spinner change Uu mouth.

It should be noted that the base station needs periodic UE broadcast system information in its sub-district, some relevant common parameters of notice UE sub-district; And after introducing RN, RN also can be periodically in RN cell to the UE broadcast system information, some relevant common parameters of notice UE sub-district.

In actual applications, the base station can be changed system information as required; But, when revising system information, can only on specific radio frames, revise system information, promptly revise system information in the modification cycle (ModificationPeriod).

Concrete, in each modification cycle, system information is constant, and identical system information can be broadcasted repeatedly, and the modification cycle is made up of some radio frames, its length is disposed by system information.And when system information need be changed in the base station, at first in a modification cycle, soon change by Paging (paging) message informing UE system information, revise system information after periodic broadcasting upgrades at the next one then.After UE received update notification, the border (for example, the modification cycle is when being second frame and the 3rd frame, then this second frame border that is the modification cycle) of revising the cycle from the next one began to read new system information.

System information is as shown in Figure 2 upgraded schematic diagram, and before UE reads new system information, UE will continue to use original system information; After UE receives new system information, can use this new system information immediately, also can enable this new system information subsequently; Promptly in the regular hour, system information and network side that UE uses may be nonsynchronous.

In the prior art, when initial configuration RN, after RN receives Un backhaul sub-frame configuration, can activate the Un mouth immediately, UE connects or is resident and because RN this moment goes up not, when activate the Uu mouth to not influence of UE, therefore when activating the Uu mouth can depend on concrete realization, only need avoid the Uu mouth to activate before the Un mouth and get final product.

But, when DeNB carries out Un backhaul subframe reprovision by RRC message to RN, RN can just enable new Un backhaul sub-frame configuration after receiving the RRC reconfiguration message, and activation Un mouth, notify the change of UE system information then, UE revises cycle boundary at the next one and begins to read new system information.

In realizing process of the present invention, the inventor finds to exist at least in the prior art following problem:

DeNB can just enable new Un backhaul sub-frame configuration after sending the RRC reconfiguration message, but DeNB can't know that RN enables backhaul and newly disposes and revise the correct time of Uu mouth configuration, thereby following situation may occur:

(1) DeNB has enabled new Un mouth backhaul sub-frame configuration, this moment, RN need revise the system information (mainly being MBSFN sub-frame information wherein) of Uu mouth, and the UE RN under reads new MBSFN sub-frame configuration and needs a period of time interval from learning that system information is changed to.If RN enables after receiving new backhaul sub-frame configuration immediately, then RN has become unicast sub in the MBFSN of Uu mouth subframe, but UE does not still go it as multicast subframe to monitor, thereby makes UE lose some packets, further also can influence the measurement of UE to RN.

(2) if RN does not enable after receiving new backhaul sub-frame configuration immediately, if the RN of DeNB scheduling during this period of time then may the packet loss problem occur at the Un mouth.

Step 602, RN reshuffles to DeNB transmission RRC connection and finishes message, and this RRC connection is reshuffled to finish and is carried the absolute time information that begins to enable descending backhaul link sub-frame configuration in the message.Wherein, this absolute time information is for activating descending backhaul link sub-frame configuration time corresponding, and is same with the ensuing some initial borderline phases of modification cycle of the Uu mouth of RN.

Concrete, after RN receives descending backhaul link sub-frame configuration, do not enable this descending backhaul link sub-frame configuration immediately, need return RRC to DeNB and connect to reshuffle and finish message and confirm, this RRC connects to reshuffle to finish and carries the absolute time information that begins to enable descending backhaul link sub-frame configuration in the message.

In addition, need to prove, be not limited in the embodiment of the invention connect to reshuffle by RRC finish message this absolute time information is sent to DeNB, this RN can also send to DeNB by other up RRC message with this absolute time information, explanation no longer in detail in the embodiment of the invention.

Step 603, DeNB activates this descending backhaul link sub-frame configuration according to this absolute time information.

According to this absolute time information, when arriving the activationary time of appointment, DeNB need activate new descending backhaul link sub-frame configuration at the Un mouth, and simultaneously, RN uses new system information at the Uu mouth.

Need to prove, before DeNB and RN activate this descending backhaul link sub-frame configuration according to this absolute time information, this RN also need be in the previous modification cycle of activationary time, and the UE in its sub-district sends the change of Paging message informing system information.At this moment, the UE under the RN begins to read new system information from this modification cycle boundary, thereby assurance Un and Uu mouth are enabled new sub-frame configuration simultaneously.

Be understandable that, when DeNB activates this descending backhaul link sub-frame configuration according to this absolute time information, can be with second next nearest system information modification cycle boundary as activationary time, also can will postpone the border in several system information modification cycle as activationary time, can select according to actual needs in the embodiment of the invention, give unnecessary details no longer in detail at this.

For technical scheme provided by the invention more clearly is described, the embodiment of the invention five proposes a kind of Activiation method of backhaul link configuration, in the present embodiment, at the Uu mouth, the system message modification cycle of RN and DcNB is consistent, and this system message is revised cycle boundary and alignd.Be that trunking is provided with identical system information modification cycle and boundary position with network equipment, and arrange coming into force constantly of descending backhaul link sub-frame configuration according to this system information modification cycle and boundary position.

As shown in Figure 7, the Activiation method of this backhaul link configuration may further comprise the steps:

Step 701, RN is with self Uu mouth and the alignment of Un mouth timing relationship.Wherein because RN can receive the downstream signal of DeNB by the Un mouth, then when RN with the Uu mouth of self with during the alignment of Un mouth timing relationship, can realize the modification cycle boundary of system message is alignd.

Specifically, RN can obtain the system message of DeNB by the system message of DeNB and revise cycle and boundary position, and at this moment, this RN only need get final product according to the system message modification cycle and the boundary position of the information configuration self that receives.

Step 702, when the descending backhaul link of DeNB reprovision sub-frame configuration, DeNB sends RRC to RN and connects reconfiguration message.Wherein, carried descending backhaul link sub-frame configuration in this RRC connection reconfiguration message, this descending backhaul link sub-frame configuration is the descending backhaul link sub-frame configuration after upgrading.

Step 703 is after RN receives descending backhaul link sub-frame configuration, from a nearest RN system information modification cycle notice UE changing system information.Wherein, this process of transmitting is specially RN from a nearest subsequently RN system information modification cycle transmission Paging notice UE changing system information.

Step 704, DeNB begins to activate this descending backhaul link sub-frame configuration at next system information modification cycle boundary.

Further need to prove, after RN receives descending backhaul link sub-frame configuration, can also notify the UE changing system information in (N-1) individual system information modification cycle subsequently, then in this step, RN and DeNB need begin to activate new Backhaul configuration at N system information modification cycle boundary.

As seen, the method that each embodiment of the application of the invention provides by arranging coming into force constantly of descending backhaul link sub-frame configuration, can realize that Un and Uu enable new sub-frame configuration simultaneously; UE uses old system information to cause packet loss at the Uu mouth after having avoided change backhaul sub-frame configuration; And avoided the generation of Un mouth packet drop after the change backhaul sub-frame configuration.
