Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.

Embodiment one

As in figure 2 it is shown, the cut-in method flow chart provided for the embodiment of the present invention one, comprise the following steps:

S201: primary nodal point sends access request message at least one secondary nodal point selected, and is used for asking Secondary nodal point, as alms giver (Donor) node of described primary nodal point, provides backhaul for described primary nodal point Service.

S202: secondary nodal point is based on the access request message received, it is judged that whether self can be as described the The Donor node of one node, and based on judged result, send to described primary nodal point and access response message.

S203: primary nodal point according to the access response message of secondary nodal point received, determine described at least one Can be as the node of the Donor node of described primary nodal point in secondary nodal point.

In S201, primary nodal point can select the secondary nodal point taking the frequency oneself supported to send access Request message, asking secondary nodal point in this access request message is oneself to carry as the Donor node of oneself For backhaul service.Primary nodal point selects the mode of secondary nodal point can have following several:

Mode one: select secondary nodal point according to nearby region measurement result;

Specifically, primary nodal point carries out nearby region measurement;According to nearby region measurement result select described at least one the Two nodes.

In specific implementation process, primary nodal point can carry out adjacent area after powering on the frequency oneself supported (here, each node can send the reference signal finding oneself for other node to signal search, such as sends out Referring now to signal), and the adjacent area searching signal is measured, determine and take the frequency oneself supported The signal measurement result of adjacent area.Such as, the frequency of primary nodal point support include 2.0GHz, 2.6GHz, 3.4GHz-3.6GHz, adjacent macro base station is operated in 2.0GHz, and adjacent small base station is (the least Stand) be operated in 3.5GHz, then primary nodal point measures these macro base stations and small station, it is thus achieved that its reference signal connects Receive power (Reference Signal Receiving Power, RSRP), reference signal quality (Reference Signal Receiving Quality, RSRQ) and Signal to Interference plus Noise Ratio (Signal to Interference plus Noise Ratio, SINR) etc. one or more in measurement result.

In being embodied as, primary nodal point can select best to measurement result based on nearby region measurement result One secondary nodal point sends access request message, or selects to send to the preferable several secondary nodal points of measurement result Access request message.Such as, the secondary nodal point that RSRP measured value is maximum can be selected, or select RSRP Measured value is more than the secondary nodal point of the RSRP threshold value preset.

Mode two, select secondary nodal point according to the backhaul information of adjacent area node.

Specifically, the backhaul information that at least one adjacent area node sends is received;According to the backhaul information received, Select at least one secondary nodal point described.

In specific implementation process, each node can broadcast the backhaul information of oneself, in order to save to other The backhaul ability of some instruction self.This backhaul information can include one or more in following information:

The backhaul hierarchical information of the jumping figure of the back haul link that the data that instruction sends through this node are experienced;

The backhaul grade of the overall characteristic of one or more in instruction back haul link attribute, time delay, handling capacity Information;Wherein, back haul link attribute includes wired backhaul, wireless backhaul link and has special microwave Back haul link;

Delay;

Throughput information.

In above-mentioned backhaul information, backhaul hierarchical information is used for instruction through returning that the data that this node sends are experienced The jumping figure of journey link, can use jumping figure the fewest, and the mode that level is the lowest indicates.Here, send out through this node The jumping figure of the back haul link that the data sent are experienced namely data arrive from this node and have wired backhaul Node or arrive have the node of special microwave back haul link or returning of arriving that IP network etc. experienced Journey number of links.Such as, for macro base station, owing to macro base station is owned by wired backhaul, therefore, grand The backhaul level of base station is 0;For having the small station of wired backhaul, its backhaul level is 0;For Having the small station of special microwave back haul link, its backhaul level is also 0;For having wireless backhaul link Small station, its backhaul level is the level after the backhaul level of its upper hop node adds 1.

Backhaul class information for indicate in back haul link attribute, time delay, handling capacity one or more combine Closing characteristic, the back haul link that handling capacity such as that time delay is less, back haul link is bigger is referred to as preferable backhaul chain Road, time delay is relatively big, that the handling capacity of back haul link is less back haul link is referred to as nonideal back haul link; By having wired preferable back haul link or can there is the returning of node of preferable back haul link of private radio microwave Journey tier definition is A level, will have wired non-ideal back haul link or has non-ideal time of private radio microwave The backhaul tier definition of the node of journey link is B level, will have the backhaul grade of the node of wireless backhaul link Being defined as C level etc., backhaul grade is followed successively by A, B, C level from high to low.

Backhaul information can also include concrete time delay and/or throughput information;Specifically, can use point The form of level indicates time delay and throughput information, such as, when time delay (referring here to one way time delay) simultaneously During<2.5us, handling capacity>10Gbps, corresponding L1 rank, when time delay is 2-5ms, and handling capacity is During 50M-10Gbps, corresponding L2 rank;When time delay is 10-30ms, and handling capacity is 10M-10Gbps, Or, time delay is 15-60ms, when handling capacity is 10M-100Mbps, and corresponding L3 rank;The above Time delay, throughout characteristic are the corresponding time delay of wired backhaul, throughout characteristic, for wireless backhaul chain Road, also corresponding L3 rank, its time delay is typically at 5-35ms, and handling capacity is typically at 10M-100Mbps, also It is likely to be breached Gbps rank.

Based on above-mentioned backhaul information, primary nodal point can select that backhaul level is relatively low, backhaul is higher ranked, time Extend to the secondary nodal point that handling capacity meets the backhaul requirements of primary nodal point, and connect to the secondary nodal point transmission selected Enter to ask message.In being embodied as, primary nodal point can determine oneself based on the business demand estimated Backhaul requirements.Such as, according to self coverage and flux density demand, determine to handling capacity Big requirements;According to service delay requirement, determine the higher limit of time delay;According to the business in coverage Required bandwidth and spectrum efficiency determine the requirements to handling capacity;The embodiment of the present invention selects secondary nodal point Process be semi-static, carry out Real-time and Dynamic with business datum based on dynamically change and determine the side of secondary nodal point Formula is compared, and signaling consumption is less.

In specific implementation process, primary nodal point can send to the one or more secondary nodal points selected and access Request message.When selecting multiple secondary nodal point, each secondary nodal point can be to meet returning of primary nodal point The node of journey demand;Or, in these multiple secondary nodal points, any node self all cannot meet primary nodal point Backhaul requirements, but multiple secondary nodal point disclosure satisfy that the backhaul requirements of primary nodal point as entirety, that is, institute State primary nodal point and send access request message to the multiple secondary nodal points selected;Wherein, described primary nodal point to The summation of the handling capacity of the back haul link of each secondary nodal point request disclosure satisfy that described primary nodal point is to backhaul The throughput demand of link.In being embodied as, primary nodal point can by adjacent area node according to backhaul characteristic by Excellent to bad descending, according to putting in order, select to set the secondary nodal point of quantity, and to this setting quantity Secondary nodal point send access request message.

Alternatively, in mode two, primary nodal point can receive arbitrary adjacent area node according in the following manner and send Backhaul information:

Primary nodal point is after accessing this adjacent area node, by this adjacent area of radio resource control RRC message sink The backhaul information that node sends;Or,

Primary nodal point receives the broadcast carrying backhaul information that this adjacent area node sends.

In specific implementation process, primary nodal point can with the identity Stochastic accessing adjacent area node of user terminal, And set up wireless heterogeneous networks (Radio Resource Control, RRC) between the node of adjacent area to connect, adjacent The backhaul information of oneself is notified to this primary nodal point by district's node by RRC information;Or, primary nodal point Reading the backhaul information that adjacent area node is notified by broadcast, here, this broadcast is to return for needs Journey link sen small station broadcast rather than for UE broadcast.

Mode three: the combination of mode one and two.

In specific implementation process, aforesaid way one and mode two can be combined and select secondary nodal point.Also That is, carry out nearby region measurement, and receive the backhaul information that at least one adjacent area node sends;According to nearby region measurement Result and the backhaul information of reception, select at least one secondary nodal point.

Such as, secondary nodal point can be selected based on RSRP measured value and backhaul level: specifically, first select Select the node that RSRP measured value is minimum more than predetermined threshold value and backhaul level, if the node selected is deposited Multiple, the secondary nodal point that RSRP measured value is maximum, Xiang Qifa can be selected again in the node selected Send access request message.

For another example, the can be selected based on RSRP measured value, backhaul level and time delay, throughput information Two nodes;Specifically, first select RSRP measured value less than predetermined threshold value and time delay, handling capacity spy The node of the backhaul requirements of sexual satisfaction primary nodal point, then select backhaul level minimum in the node selected Node, if the minimum node of the backhaul level selected exists multiple, selects in the node selected the most again The secondary nodal point that RSRP measured value is maximum, is sent to access request message.

For another example, if node cannot meet the throughput demand of primary nodal point, multiple second can be selected Node meets the backhaul requirements of primary nodal point jointly.Specifically, can first select RSRP measured value little In multiple nodes of predetermined threshold value, by these multiple nodes according to backhaul characteristic by excellent to bad descending, press According to putting in order, select multiple secondary nodal points of the backhaul requirements that can jointly meet primary nodal point;At this During, if there is the node that multiple backhaul characteristic is identical, and have only to select this multiple backhaul characteristic phases With node in part of nodes time, the node that wherein backhaul level is minimum can be selected, if backhaul level is The number of low node is still beyond demand, then during reselection goes out the node that these backhaul levels are minimum, RSRP surveys The secondary nodal point that value is maximum, is sent to access request message.

Aforesaid way one and mode two combine the embodiment of the mode three obtained to be had multiple, the embodiment of the present invention In only make above illustration, any specific embodiment party that mode one and mode two are combined the mode three obtained Formula is all in scope.

In S201, the secondary nodal point that primary nodal point selects can be macro base station (DeNB), it is also possible to be Small station;Wherein, the back haul link of macro base station is wire-line back haul, and corresponding backhaul level is 0, macro base station work Making at 2.0GHz, system bandwidth may be less, so, and the wireless link between macro base station and primary nodal point Bandwidth less, possibly cannot meet the backhaul requirements of primary nodal point.The secondary nodal point that primary nodal point selects can To be small station, being such as AP, if the backhaul level of AP is 0, then AP has wire-line back haul, or has specially By microwave backhaul, the bandwidth of the wireless link between AP and this primary nodal point may be less, works as primary nodal point Backhaul requirements bigger time, possibly cannot meet the demand of primary nodal point;If the backhaul level of AP is more than 0, Then the back haul link of AP is wireless backhaul link, and when the backhaul requirements of primary nodal point is bigger, possibly cannot Meet the demand of primary nodal point.In these cases, if node cannot meet the backhaul need of primary nodal point Ask, then multiple node can be selected to provide backhaul service for primary nodal point together, to meet returning of primary nodal point Journey demand.

In S202, secondary nodal point based on receive access request message, it is judged that self whether have the ability be Primary nodal point provides backhaul service, and based on judged result, sends to primary nodal point and accept or refusal conduct The access response message of Donor node.

Alternatively, can include in following information during primary nodal point is sent to the access request message of secondary nodal point One or more:

The frequency of described primary nodal point support and bandwidth;

The backhaul requirements information of described primary nodal point;Described backhaul requirements information includes time delay and/or handling capacity Demand information;

The nearby region measurement result of described primary nodal point.

Alternatively, secondary nodal point access request based on primary nodal point message, and the one in following information Or multiple, it is judged that whether self can be as the Donor node of described primary nodal point:

The frequency of described secondary nodal point support and bandwidth;

Indicate the information of the access link characteristic of described secondary nodal point;

Indicate the information of the back haul link characteristic of described secondary nodal point.

Here, the information of the access link characteristic of described secondary nodal point, the access under such as secondary nodal point are indicated The information such as the bandwidth of link, load;The back haul link of secondary nodal point namely secondary nodal point and its upper hop node Between back haul link, the information of back haul link characteristic of instruction secondary nodal point can include the backhaul of secondary nodal point The information such as the time delay of link, handling capacity, load.

In specific implementation process, secondary nodal point can consider frequency and the bandwidth self supported, this second section The existing time delay of back haul link of point, handling capacity and load, the information such as the bandwidth of responsible access link and load In one or more, and the information in access request message that combines judges whether to carry for primary nodal point For backhaul service, if disclosure satisfy that the backhaul requirements of primary nodal point.Alternatively, secondary nodal point is determining certainly During the backhaul requirements of the primary nodal point that body can be supported, can be own reservation part surplus, to prevent business The impact of fluctuation, such as, if the handling capacity of primary nodal point request is Xbps, if this secondary nodal point can The handling capacity size provided is not less than (X+delta1) bps, then secondary nodal point confirms to disclosure satisfy that first segment The point demand to handling capacity, delta1 is the handling capacity surplus that secondary nodal point is reserved.In like manner, if first The time delay of node request is Y ms, if the time delay size that this secondary nodal point can provide is not more than (Y-delta2) Ms, then secondary nodal point confirms to disclosure satisfy that the primary nodal point demand to time delay, and it is pre-that delta2 is secondary nodal point The time delay surplus stayed.

Such as, the access request message that primary nodal point sends comprises the frequency that primary nodal point is supported, then second The frequency comprised in the frequency that node is supported based on self, and the access request message of primary nodal point, it is judged that be No can be as the Donor node of primary nodal point.Such as, the frequency that secondary nodal point self is supported is f1, In the access request message of primary nodal point, the frequency of the primary nodal point support of instruction is f1 and f2, then second Node represents the acceptance access response message as Donor node to what primary nodal point sent, wherein comprises back The frequency f1 that journey link uses.

For another example, the access request message that primary nodal point sends comprises the demand of the handling capacity to backhaul service Information, then secondary nodal point handling capacity based on self existing back haul link, it may be judged whether can be as first The Donor node of node.Such as, the handling capacity of the existing back haul link of secondary nodal point is 100Mbps;First In the access request message of node, the handling capacity of request is 60Mbps, and secondary nodal point determines existing backhaul chain Handling capacity 100Mbps on road > 60Mbps+delta1 (delta1=10Mbps), it is possible to meet primary nodal point Demand, then represent the acceptance access response message as Donor node to what primary nodal point sent, wherein wrap Handling capacity 60Mbps containing the backhaul service that can provide.Here, secondary nodal point is receiving primary nodal point Access request message after, can give tacit consent to and the frequency self taken comprises the frequency that primary nodal point is supported.

For another example, the access request message that primary nodal point sends comprises nearby region measurement result, then secondary nodal point Each frequency supported based on self, and each frequency of correspondence comprised in the access request message of primary nodal point Nearby region measurement result, it may be judged whether can be as the Donor node of primary nodal point.Such as, primary nodal point Access request message in comprise measurement frequency f1, f2 and f3, and each frequency indicated by nearby region measurement result On disturbed condition: interference suffered on f1 frequency > interference suffered on f2 frequency > suffered on f3 frequency Interference, the frequency of secondary nodal point support is f1 and f2, then interference corresponding during secondary nodal point selects f1 and f2 Less frequency f2 provides backhaul service for primary nodal point, and secondary nodal point sends to primary nodal point and represents acceptance As the access response message of Donor node, wherein comprise the frequency f2 that back haul link uses.

For another example, the access request message that primary nodal point sends comprises the frequency of support, primary nodal point to gulping down The demand information of the amount of telling and nearby region measurement result, then secondary nodal point is based on self existing back haul link Handling capacity, the information such as the frequency of responsible access link, load, it may be judged whether can be as primary nodal point Donor node.Such as, the frequency of secondary nodal point support is f1, f2, and the frequency of responsible access link is F1, load is 40%, and the handling capacity of existing back haul link is 100Mbps;The access request of primary nodal point disappears In breath, the support frequency of instruction is f1, f2 and f3, and the handling capacity of request is 60Mbps, and nearby region measurement is tied The disturbed condition on each frequency indicated by Guo is: interference suffered on f1 frequency > suffered dry on f2 frequency Disturb interference suffered on f3 frequency;Secondary nodal point determines the handling capacity of existing back haul link 100Mbps > 60Mbps+delta1 (delta1=10Mbps), owing to f1 frequency is the frequency that access link uses Point, load is higher and interference is relatively big, and therefore, selecting the frequency f2 of load relatively low (use) is the One node provides backhaul service, then send to primary nodal point and represent that acceptance responds as the access of Donor node Message, wherein comprises the handling capacity of back haul link the frequency f2 used and the backhaul service that can provide 60Mbps。

Alternatively, in S202, can only provide in the handling capacity that primary nodal point is asked if secondary nodal point determines Part handling capacity, then accessing in response message of sending can include the part that this secondary nodal point can provide The information of handling capacity.

Such as, the frequency of secondary nodal point support is f1, f2, and the frequency of responsible access link is f1, bandwidth For 20MHz, load is 40%, and the handling capacity of existing back haul link is 50Mbps;The access of primary nodal point In request message, the frequency of support is f1, f2 and f3, and the handling capacity of request is 60Mbps, nearby region measurement The disturbed condition on each frequency indicated by result is: interference suffered on f1 frequency > suffered on f2 frequency Interference > interference suffered on f3 frequency;Secondary nodal point determines the handling capacity of existing back haul link 50Mbps < 60Mbps+delta1 (delta 1=10Mbps), only meets part backhaul requirements, due to f1 frequency The frequency that point uses for access link, load is higher and interference is relatively big, therefore, selects load relatively low (not Use) frequency f2 provide backhaul service for primary nodal point, then to primary nodal point send expression accept conduct The access response message of Donor node, the frequency f2 wherein comprising support and the backhaul service that can provide Handling capacity 50Mbps-delta1=40Mbps.

Alternatively, if described secondary nodal point can only provide the part in the handling capacity that described primary nodal point asks to gulp down The amount of telling, the most described method also includes:

Specifically, secondary nodal point sends backhaul dilatation request message at least one the 3rd node, including:

Secondary nodal point sends backhaul dilatation request to the 3rd node of the Donor node as secondary nodal point and disappears Breath;And/or,

Secondary nodal point sends access request message, for request selecting to the 3rd node not accessed selected 3rd node, as the Donor node of secondary nodal point, provides backhaul service for this secondary nodal point;This access please Message is asked to include the secondary nodal point demand information to the handling capacity of backhaul service.

In being embodied as, if secondary nodal point can only provide the part in the handling capacity that described primary nodal point is asked Handling capacity, then can be first at least one the 3rd node request dilatation backhaul service, after dilatation success, Send to primary nodal point again and access response message, access response message now can include this primary nodal point The information of whole handling capacities of request.

In S202, if secondary nodal point determines can not provide backhaul service for primary nodal point, can be to first Node sends the access response message representing refusal as Donor node.

Such as, the frequency of secondary nodal point support is f1, f2, and the frequency of responsible access link is f1, bandwidth For 20MHz, load is 80%, and the handling capacity of existing back haul link is 50Mbps;The access of primary nodal point In request message, the frequency of support is f1 and f3, and the handling capacity of the back haul link of request is 60Mbps, adjacent The disturbed condition on each frequency indicated by region measurement result is: interference suffered on f1 frequency > on f3 frequency Suffered interference;Secondary nodal point determines the handling capacity 50Mbps < 60Mbps+delta1 of existing back haul link (delta1=10Mbps), part backhaul requirements is met, but, secondary nodal point can be supported and first segment The identical f1 frequency of point is the frequency that access link uses, and load is higher and interference is bigger, it is impossible to provide back Journey services, and therefore, secondary nodal point sends the access response message representing refusal as Donor node.

In S203, primary nodal point according to the access response message of secondary nodal point received, determine described in extremely A few secondary nodal point as the node of alms giver's Donor node of described primary nodal point, and can access really Fixed node.Such as, if the instruction in response message that accesses of secondary nodal point accepts the alms giver as primary nodal point Donor node, then can select this secondary nodal point to access as Donor node.

Specifically, primary nodal point is according to the access response message of the secondary nodal point received, it may be judged whether have one Individual secondary nodal point disclosure satisfy that the backhaul requirements of described primary nodal point, and this backhaul requirements includes the need to handling capacity Ask;If existing, then select this secondary nodal point Donor node as described primary nodal point of existence;Otherwise, If there is multiple secondary nodal point do not refuse the alms giver's Donor node as primary nodal point, and the plurality of second The summation of the handling capacity of the back haul link that node can provide meets the backhaul requirements of described primary nodal point, then select Select the plurality of secondary nodal point Donor node as primary nodal point.

After S203, primary nodal point can send access confirmation message to the Donor node determined, uses Confirm to be provided backhaul service by this Donor node for primary nodal point in instruction.

Correspondingly, secondary nodal point, after receiving the access confirmation message that primary nodal point sends, confirms to need to make For the Donor node of described primary nodal point, provide backhaul service for described primary nodal point.

Here, secondary nodal point needs to provide after backhaul service for primary nodal point determining, can first carry out into Primary nodal point provides the preparation of backhaul service, is such as open at and accesses feed back in response message and primary nodal point Between the frequency that used of back haul link, carry out resource reservation for this backhaul service, such as reserving is One node provides the handling capacity etc. of backhaul service.

In S203, if primary nodal point is according to the access response message of the secondary nodal point received, determine transmission The secondary nodal point accessing response message all refuses the Donor node as primary nodal point, or does not refuse to make The handling capacity that can be provided by for the secondary nodal point of alms giver's Donor node of described primary nodal point is unsatisfactory for first segment The demand of point, then primary nodal point can reselect at least one second section after predetermined time period Point, and send access request message at least one secondary nodal point reselected.

Alternatively, after S203, primary nodal point based on a determination that the access response message of Donor node, Determine the backhaul information of self, in order to provide backhaul service for other node.

In specific implementation process, after primary nodal point is defined as the Donor node of oneself offer backhaul service, Characteristic based on the back haul link between self and this Donor node (can include what this back haul link used Frequency and bandwidth, the backhaul requirements etc. that Donor node is supported), determine the backhaul information of primary nodal point oneself, The information such as including backhaul level, backhaul grade, time delay, handling capacity, in order to whenever necessary, by broadcast Or RRC information form is sent to other node, provide backhaul service for other node.Here, for returning This backhaul information of journey level, if primary nodal point provides the backhaul layer of multiple Donor nodes of backhaul service Level is inconsistent, then after the level of the maximum node of backhaul level in multiple Donor node can be selected to add 1 It is worth the level as oneself.
