Description

Method, equipment and system that bandwidth is adjusted

Technical field

The present invention relates to communication technical field, relate in particular to method, equipment and system that a kind of bandwidth is adjusted.

Background technology

In mobile bearer network, base station and base station controller use low speed chain circuit to be linked in the bearer network, communicate by bearer network.At present, low speed chain circuit is mainly the E1 link of E1 link or link channel (Channelizing POS (Packet Over SDH/Sonet) is called for short CPOS).In order to increase effective bandwidth, generally many E1 multilink bundlings can be pooled point-to-point protocol binding group (Multilink Point to Point Protocol, be called for short MLPPP) or ATM (synchronous Transfer Mode, asynchronous transfer mode) inverse multiplexing technology binding group (Inver se Multiplexing ATM is called for short IMA) is in order to increase access bandwidth.Usually, base station and MLPPP or IMA binding group that base station controller uses the E1 link aggregation to become are linked in the bearer network, communicate by bearer network.From networking, base station side normal operation E1 link bundlees and converges, and the side of base station controller then E1 link of normal operation CPOS bundlees and converges.

In the communication process between base station and base station controller, the bandwidth of local access loading network should be consistent with the bandwidth of opposite end access loading network, and namely the E1 number of links in the local binding group should equate with the E1 number of links in the opposite end binding group.If the E1 link occurs fault in this locality or the opposite end binding group causes the access bandwidth at two ends inconsistent, then can make online user's circuit domain business Quality Down, reduce the service quality (Quality of Service is called for short QoS) of customer service.Therefore, when the E1 of this locality number of links changes, need a kind of bandwidth adjusting mechanism notice opposite end to adjust the E1 number of links, so that the bandwidth that the communication two ends are linked in the bearer network is consistent.

Present bandwidth adjusting mechanism mainly is that when the E1 number of links in this locality binding group changed, local device to the upper wire tube apparatus, was then adjusted the E1 number of links of opposite end by alarm report manually.Although this bandwidth adjusting mechanism can be consistent with the E1 number of links adjustment at communication two ends, the adjustment time is longer, and for the circuit domain business for delay sensitive, this adjustment cycle is larger on the communication quality impact of carrier class business.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.

For ease of follow-up inventive embodiments is described, at first to the embodiment of the invention based on the network architecture simply introduce.As shown in Figure 1, in the framework that base station and base station controller communicate, the base station is connected in the bearer network by router one by binding group 1, base station controller is connected in the bearer network by router two by binding group 2, and base station and base station controller are by bearer network and binding group separately and router realization data interaction.Usually, comprise multilink in the binding group, every link provides certain bandwidth, multilink is bundled to converge form the binding group, can improve the communication bandwidth between base station and the base station controller.

Based on the network architecture shown in Figure 1, the method that the embodiment of the invention provides a kind of bandwidth to adjust, as shown in Figure 2, described method comprises:

201, when detecting the first binding group link quantity and change, the first equipment obtains the current number of links of the first binding group.

Described the first equipment can be the router one among Fig. 1, and corresponding the first binding group is the binding group 1 among Fig. 1.In addition, described the first equipment also can be the router two among Fig. 1, and corresponding the first binding group is the binding group 2 among Fig. 1.Router one take the first equipment as access base station in the embodiment of the invention describes as example, and corresponding the second equipment is the router two of access base station controller.Should be clear and definite, equipment is carried out the one the second differentiation only for ease of describing, as the restriction to the embodiment of the invention.

The first binding group and the first equipment connection are used for the base station is connected to the first equipment.Usually, the first binding group can be converged by 16 to 32 multilink bundlings and form, in the embodiment of the invention not the concrete number of links to the first binding group limit.

When the first equipment Inspection changes to the first binding group link quantity, obtain the current number of links of the first binding group, described current number of links is the number of links that the first binding group comprised after the first binding group link quantity changed.The first binding group link quantity changes and specifically comprises: because some link occurs fault can't use the number of links that causes to reduce, perhaps, increase because faulty link recovers the available number of links that causes.Described in the embodiment of the invention or the current number of links of similar described the first binding group refer to the available and current number of links of using in the first binding group, the link total quantity in no more than the first binding group of this number of links.Link in the binding group is according to the use state link that can be divided three classes: 1) the unavailable link of fault, 2) the available and current link that is using, 3) available but current untapped link.Current number of links described in the embodiment of the invention is the available and current link that is using.

202, the first equipment generates the indication message, adds the current number of links that number of links changes indication and the first binding group in this indication message.

This indication message is used to indicate the second equipment is adjusted the second binding group according to the current number of links of the first binding group number of links.The number of links of described adjustment the second binding group increases and decreases for the current number of links to the second binding group, so that the current number of links of the second binding group equates with the current number of links of the first binding group.

Described indication message can be the exclusive message that privately owned message also can be based on the bearer network transmission means, and the present invention does not do restriction to type of message and message format.

203, the first equipment indication message that will generate sends to the second equipment.

The indication message that the first equipment will generate sends to the second equipment, so that the second equipment is adjusted number of links in the second binding group according to this indication message.Described the second binding group and the second equipment connection.In Fig. 1, the second equipment is router two, and corresponding the second binding group is binding group 2.

The second equipment at first changes indication according to the number of links of carrying in the indication message indication message is identified after receiving the indication message, and identifying this indication message is link change notice message.Then the second equipment obtains the current number of links of the first binding group that indication carries in the message, and compares with the current number of links of the second binding group.If the current number of links of the first binding group and the second binding group is equal, then the second equipment is not adjusted the current number of links of the second binding group; If the current number of links of the first binding group is greater than the current number of links of the second binding group, then the second equipment is many link activations to be activated, thereby the current number of links of the second binding group is increased to the quantity that equates with the current number of links of the first binding group; If the current number of links of the first binding group is less than the current number of links of the second binding group, then the second equipment is removed the link that has more than the first binding group in the second binding group.Thus that the first binding group is consistent with the number of links adjustment of the second binding group.

In the prior art, when the number of links in the binding group 1 changes, the current number of links of binding group 1 reported the upper strata gateway device after router one will change, then current number of links after the network manager obtains and changes in the binding group 1 manually adjusts current number of links in the binding group 2 according to tying up current number of links in the group 1.Because artificial reaction can not reach other reaction speed of communication stage, and Network Management Equipment to the base station or the physical distance of base station controller far away, so the time cycle that bandwidth is adjusted is longer.

The method that the bandwidth of the embodiment of the invention is adjusted, send the indication message by the first equipment to the second equipment in the time of can changing in the current number of links of the first binding group, in this indication message, carry the number of links that changes for the sign number of links and change the current number of links of indicating and changing rear the first binding group, so that the second equipment according to this indication message with the current number of links of the second binding group be adjusted into change after the identical quantity of the current number of links of the first binding group, thereby the first equipment is consistent with the bandwidth adjustment at the second equipment two ends.Because the first binding is organized notification message that current number of links changes and is sent to the second equipment by the first equipment with the form of message, so compare with the artificial current number of links of adjusting the second binding group in the prior art, second equipment of can saving is adjusted the time of bandwidth, eliminates bandwidth and adjusts overlong time to the impact of carrier class quality of service.

The method that the embodiment of the invention also provides another kind of bandwidth to adjust, as shown in Figure 3, described method comprises:

301, the second equipment receives indication message and/or the confirmation message that the first equipment sends.

When the first equipment can be for the router one among Fig. 1, described the second equipment was the router two among Fig. 2, and corresponding, the second binding group is binding group 2.Router one take the first equipment as access base station in the embodiment of the invention, the second equipment describe as the router two of access base station controller as example.Should be clear and definite, equipment is carried out the one the second differentiation only for ease of describing, as the restriction to the embodiment of the invention.

The second binding group and the second equipment connection are used for base station controller is connected to the second equipment.Usually, the second binding group can be converged by 16 to 32 multilink bundlings and form, in the embodiment of the invention not the concrete number of links to the second binding group limit.

When the first equipment Inspection changes to the first binding group link quantity, can send indication message or confirmation message to the second equipment, in this indication message or confirmation message, carry the current number of links of the first binding group after changing.Described indication message or described confirmation message are used to indicate the second equipment and adjust number of links in the second binding group according to the current number of links of the first binding group after changing.In the embodiment of the invention, the number of links of described adjustment the second binding group increases and decreases for the current number of links to the second binding group, so that the current number of links of the second binding group equates with the current number of links that changes rear the first binding group.

In the embodiment of the invention, described indication message or described confirmation message can be the exclusive messages that privately owned message also can be based on the bearer network transmission means, and the present invention does not do restriction to type of message and message format.

302, the second equipment obtains the current number of links of the first binding group in indication message or the confirmation message.

Receive indication message that the first equipment sends as example take the second equipment: the second equipment changes indication according to the number of links in the indication message and identifies the number of links that this indication message is used to indicate the first binding group variation has occured behind the indication message that first equipment that receives sends.The second equipment obtains the current number of links of the first binding group of carrying in the indication message.

After the second equipment received the affirmation message that the first equipment sends, the second equipment confirmed that according to the number of links in the confirmation message indication identifies the number of links that this confirmation message is used to indicate the first binding group variation has occured.The second equipment obtains the current number of links of the first binding group of carrying in the confirmation message.

303, the second equipment determines whether the current number of links of the first binding group equates with the current number of links of the second binding group.

Wherein the current number of links of the first binding group is the current number of links of the first binding group after changing, i.e. the current number of links of the first binding group of obtaining from indication message or confirmation message of the second equipment.The second equipment compares the current number of links of the first binding group and the current number of links of the second binding group, draw thus the former greater than, equal or less than the latter, with this as 304 adjustment foundation.

304, the second equipment equates the current number of links in the second binding group and described the first binding group according to determining that the result adjusts the current number of links of the second binding group.

Concrete, when the current number of links of the first binding group equaled the current number of links of the second binding group after changing, the second equipment abandoned indication message or confirmation message, then carries out proper communication with the first equipment.When the current number of links of the first binding group is less than the current number of links of the second binding group after changing, the link that the second equipment Removal the second binding group has more than the first binding group.For example, if the current number of links of the first binding group is 12 after changing, the current number of links of the second binding group is 16, then 4 links in the second equipment Removal the second binding group.When the current number of links of the first binding group is greater than the current number of links of the second binding group after changing, the difference that current number of links is organized in current number of links and the second binding was organized in the first binding after the second equipment calculate to change, and activated the link to be activated of difference quantity in the second binding group.For example, if the current number of links of the first binding group is 16 after changing, the current number of links of the second binding group is 12, and then to calculate both differences be 4 links of 4, the second device activations to the second equipment, so that the current number of links of the second binding group becomes 16.Thus that the first binding group is consistent with the number of links adjustment of the second binding group.

Need to prove, the link in the binding group is according to the use state link that can be divided three classes: 1) the unavailable link of fault, 2) the available and current link that is using, 3) available but current untapped link.Current number of links described in the embodiment of the invention is the available and current link that is using, and the link of the second device activation is available but current untapped link.The second equipment with available but current untapped link activation after, this link becomes the available and current link that is using.

The method that the bandwidth of the embodiment of the invention is adjusted, the second equipment can be behind indication message or confirmation message that first equipment that receives sends, change indication or number of links according to the number of links of carrying in this indication message or the confirmation message and confirm that indication recognizes the first binding and organizes current number of links and change, then obtain the current number of links of the first binding group after the variation of carrying in indication message or the confirmation message, according to this indication message with the current number of links of the second binding group be adjusted into change after the quantity that equates of the current number of links of the first binding group, thereby the first equipment is consistent with the bandwidth adjustment at the second equipment two ends.Because the second equipment receives the notification message that current number of links variation is organized in the first binding with the form of message, and automatically adjust the current number of links of the second binding group according to this notification message, so compare with the artificial current number of links of adjusting the second binding group in the prior art, second equipment of can saving is adjusted the time of bandwidth, eliminates bandwidth and adjusts overlong time to the impact of carrier class quality of service.

In Fig. 2 and embodiment shown in Figure 3; it is the E1 link of E1 link or CPOS channelizing that link in the binding group includes but are not limited to; usually pool the binding group by the E1 multilink bundling between base station and the router, the E1 multilink bundling by the CPOS channelizing between base station controller and the router pools the binding group.To include but are not limited to be MLPPP binding group or IMA binding group to the binding group in the embodiment of the invention.

In Fig. 2 and embodiment shown in Figure 3, base station and base station controller can access in the multiple bearer network, pseudo wire emulation (the Pseudo-Wire Emulation Edge to Edge of the follow-up edge-to-edge with L2VPN of the present invention, abbreviation PWE3) network is that example describes as the bearer network of base station and base station controller access, and the step in the embodiment of the invention and parameter are expanded and described in detail in conjunction with the characteristics of PWE3 network, will be clear that, take the PWE3 network as bearer network only as the embodiment of the invention a kind of one of may implementation, in the practical application, bearer network for other kinds, those skilled in the art can in conjunction with the PWE3 network as the implementation of bearer network and in conjunction with the species characteristics of other kind bearer networks, under the prerequisite of not paying creative work, realize the bandwidth adjustment.The embodiment of the invention is not enumerated one by one to the bandwidth adjustment mode based on other kind bearer networks.

At first, as further expanding the present invention embodiment shown in Figure 2, before step 201, when the first equipment is being connected in the PWE3 network, the first equipment generates confirmation message, the current number of links of the first binding group when this confirmation message adds number of links affirmation indication and initialization.Then the first equipment sends to the second equipment with confirmation message.

Alternatively, unstable second equipment that causes of Internet Transmission is missed confirmation message when avoiding initialization, the first equipment can repeatedly send confirmation message to the second equipment according to predetermined period, and for example the first equipment sends continuous the transmission 3 times of confirmation message every 3ms (millisecond) one time to the second equipment.

Similarly, the second equipment also can generate confirmation message, and the current number of links of the first binding group sends to the first equipment during with initialization, the number of links that the first binding group and the second binding group are used when consulting to determine initialization with the first equipment.

Alternatively, unstable first equipment that causes of Internet Transmission is missed confirmation message when avoiding initialization, the second equipment also can repeatedly send confirmation message to the first equipment according to predetermined period, and for example the second equipment sends continuous the transmission 3 times of confirmation message every 3ms (millisecond) one time to the first equipment.

The first equipment and the second equipment consult to determine a smallest link coupling numerical value, the less number of links of current number of links in the first binding group and the second binding group when this numerical value is initialization.For example, the current number of links of the first binding group is 12 during initialization, the current number of links of the second binding group is 16, then to consult to draw a smallest link coupling numerical value be 12 for the first equipment and the second equipment, binding is organized the more side of current number of links (the second equipment) and is removed 4 links, make the current number of links of front the second binding group become 12, finish thus the initialization of number of links.

After finishing the number of links initialization, the first equipment quilt and the second equipment carry out proper communication.When the first device link quantity changed, step 201 was notified the number of links of the first binding group after changing to the second equipment to step 203 in the first equipment order execution graph 2.Further, as further expanding the embodiment of the invention, for avoiding the Internet Transmission conditional instability to cause the second equipment not receive the indication message, the first equipment can also be after sending the indication message, generate confirmation message, number of links is confirmed the number of links of indication and rear the first binding group of variation is added in the confirmation message.The first equipment repeatedly sends confirmation message according to predetermined period to the second equipment, for example the first equipment sends continuous the transmission 3 times of confirmation message every 3ms (millisecond) one time to the second equipment, can receive the number of links that changes rear the first binding group to guarantee the second equipment.

After the variation of adding in the confirmation message after the number of links of the first binding group and the variation that indication is added in the message number of links of the first binding group identical, and the priority of confirmation message is lower than the priority of indication message.If the second equipment has received the indication message, then when receiving the confirmation message, the second equipment is not processed confirmation message, can directly it be abandoned.

Further, as the response to indication message or confirmation message, the second equipment can also generate a response message and feed back to the first equipment according to after indicating message or confirmation message to adjust the second binding group number of links.Concrete, the second equipment is confirmed to indicate by number of links and the current number of links of rear the second binding group of adjustment is added in this response message, and response message is sent to the first equipment.

If the available link quantity in the second binding group (the available and current number of links of using and available but current untapped number of links sum) is less than the number of links of the first binding group after changing, in any case then the second equipment adjustment number of links all can not be adjusted to the number of links of the second binding group the quantity that equates with the number of links of the first binding group.This moment the second equipment with all available but current untapped link activation, and after the current number of links of the second binding group adjusted to maximum, the current number of links of the second binding group after adjusting added to sending to the first equipment in the response message, so that the first equipment reduces current number of links in the first binding group according to the current number of links of the second binding group after adjusting.

The first equipment is after receiving response message, and whether the current number of links of the second binding group equates with the current number of links that changes rear the first binding group after determining to adjust.Determine that result and processing mode have following three kinds of situations:

1) if the current number of links of the first binding group equates with the current number of links of adjusting rear the second binding group after changing, then the first equipment and the second equipment carry out proper communication.

2) if the current number of links of the first binding group is greater than the current number of links of the second binding group after adjusting after changing, the link that has more than the second binding group of the first equipment Removal the first binding group then.For example, the current number of links of the first binding group is 16 after changing, and the current number of links of the second binding group is 12 after adjusting, then receive response message after, the first equipment removes 4 links from the link of the current use link of the first binding group.

3) if the current number of links of the second binding group less than the current number of links of the first binding group after adjusting, then the first equipment sends the indication message to the second equipment again, it specifically can be to resend the indication message that generates among Fig. 2 that the first equipment sends this indication message again, also can be to step 202 the indication message that regenerates to be sent to the second equipment according to step 201 in the current number of links of the first binding group again precedence diagram 2.

Further, for situation 2), when the first equipment removes 4 links from the link of the current use link of the first binding group after, the first equipment also needs to generate a response message, the current number of links (12) of the first binding group behind the dismounting link is added to sending to the second equipment in this response message.The implementation that the first equipment generates response message is identical with the implementation of aforementioned the second equipment generation response message to be repeated no more herein.

In addition, when the second equipment the current number of links of the second binding group is adjusted to maximum after (12) during still less than the current number of links (16) of the first binding group, the second equipment is after the first equipment sends response message, sequentially step 201 is carried the indication message that current number of links (12) organized in rear the second binding of adjustment to step 203 to the transmission of the first equipment in the execution graph 2.Current number of links (16) was organized in the first binding after the second binding was organized current number of links (12) adjustment and changed after the adjustment that the first equipment carries in can be not according to response message behind the response message that second equipment that receives sends.The first equipment is follow-up receive the indication message that the second equipment sends after, according to the indication message current number of links is organized in the first binding again and is reduced to 12, and send response message to the second equipment.

This shows, it is disposable adjustment that the process of bandwidth adjustment is not limited to, and also can be the process of repeatedly consulting between the first equipment and the second equipment, and the embodiment of the invention does not limit the number of times of bandwidth adjustment.

In embodiments of the present invention, only for ease of the usefulness of description, in fact the first equipment can also have the correlation function of the second equipment in the differentiation of the first equipment and the second equipment, i.e. the correlation step of the first equipment in can execution graph 3; Equally, the second equipment also can have the correlation function of the first equipment, i.e. the correlation step of the second equipment in can execution graph 2.

Indication message, confirmation message and response message in the embodiment of the invention can be the exclusive message based on bearer network, also can be privately owned message.Below, the message format of the embodiment of the invention is elaborated, the message in the following declarative procedure comprises indication message, confirmation message and response message, follow-uply simply describes it with message.

1) exclusive CSF message.When bearer network is the PWE3 network, message is MPLS transmission characteristic assembly (MPLS Transport Profile Operations, Administration and Maintenance, abbreviation MPLS-TPOAM) acts on behalf of faulty indication (Client Failure Indication in, abbreviation CFI) the proxy signal reduction in the assembly (Client Signal Failure is called for short CSF) message.Wherein MPLS is multiprotocol label switching (Multi-Protocol Label Switching).Because the CSF message can be disposed based on the pseudo-line (PW) of PWE3 network, and support two-way detection and dynamic PW and static PW, therefore can under the existing transmission architecture of PWE3 network, realize transmitting, can well carry out combination with the PWE3 network.The first equipment transmits mutually the CSF message by PW and the second equipment.

The form of existing CSF message comprises CSF header fields (MPLS-TP CSF field), reserved field 1 (Reserved 1 field), attribute field (Flags field) and reserved field 2 (Reserved 2 fields) in the CSF message shown in Fig. 4 (a).Wherein, shown in Fig. 4 (b), attribute field (Flags) comprises again the reserved field (Res field) of 2bit, the type field (the type field) of 3bit and the period field (Period field) of 3bit.

In a possibility of the embodiment of the invention, when the first equipment generates the indication message, the first equipment the type field is set to binary one 10, change indication with 110 as number of links, the current number of links of the first binding group after changing is added in Reserved 1 field with binary form, for example, when the first equipment when Reserved 1 field arranges 1100, the current number of links of the first binding group was 12 after expression changed; When the first equipment generated confirmation message, the first equipment the type field was set to 101, confirmed indication with 101 as number of links, and the current number of links of the first binding group after changing is added in Reserved 1 field with binary form; When the second equipment generated response message, the second equipment the type field was set to binary one 01, confirmed indication with 101 as number of links, and the current number of links of the second binding group after adjusting is added in Reserved 1 field with binary form.

2) privately owned PW message.To PW message encapsulation PW control word and PW label, then by PWE3 Internet Transmission PW message.For the PW control word of MLPPP, the 4bit to 7bit that takies the PW message fills special field, is special control message with this PW message identification.Encapsulate current number of links with binary form in the PW label.The receiving terminal end receives that identifying it by the PW control word behind the PW message is special control message, obtains the number of links of carrying in the PW label.

3) private network protocol IP (Internet Protocol is called for short IP) message.Setting up transmission control protocol (Transmission Control Protocol is called for short TCP) between the first equipment and the second equipment connects.The first equipment and the second equipment are by the transmission of route implementing IP message.Existence by the regular notification device of keepalive message (being equivalent to confirmation message).When the number of links of the binding group of certain equipment connection changed, this equipment sent the private ip message to another equipment, carries current number of links in this IP message.The private ip message is applicable to the scene of disposing IP network in the bearer network.

Need to prove, the type of message of indication message, confirmation message and the response message described in the embodiment of the invention can be in above-mentioned three kinds of type of messages any one, but indicates the type of message of message, confirmation message and response message must be simultaneously a certain type in above-mentioned three kinds of type of messages.Logical which kind of transmission means between the first equipment and the second equipment (PW transmission or IP route transmission) is carried out message transmissions, and the type of message of indication message, confirmation message and response message is type of message corresponding to which kind of transmission means just.

The below is take the CSF message as example, and an application scenarios of the embodiment of the invention is described.In scene shown in Figure 5, the base station is connected to router one by the MLPPP binding group 1 that 8 E1 multilink bundlings converge formation, the MLPPP binding group 2 that the E1 multilink bundling of base station controller by 8 CPOS channelizings converges formation is connected to router two, and router one and router two are connected in the PWE3 network.During initialization, the number of links that router one gets access to the current use of base station is 8, this number of links is announced oam state machine to this router, generate the CSF confirmation message, Reserved 1 field of CSF confirmation message is set to 1000 (number of links is 8), and the type field is set to 101 (number of links is confirmed indication).Then router one periodically sends to router two by PW with the CSF confirmation message; Meanwhile, the number of links that router two gets access to the current use of base station controller is 8, this number of links is announced OAM (Operations to this router, Administration and Maintenance, operation management maintain is called for short OAM) state machine, generate and confirm the CSF message, Reserved 1 field of CSF confirmation message is set to 1000 (number of links is 8), and the type field is set to 101 (number of links is confirmed indication).Then router two periodically sends to router one by PW with the CSF confirmation message.In this application scene, the initialization link quantity of MLPPP binding group 1 and MLPPP binding group 2 is 8, need not adjust, so after receiving the CSF confirmation message, router one and router two send a CSF response message to the other side respectively, Reserved 1 field is set to 1000 in the CSF response message, and the type field is set to 101.Then router one and router two carry out proper communication by PWE 3 networks.
