Embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
As shown in Figure 1, in the embodiment of the invention, the multi-link management system of mobile communication multi-service comprises: trigger module 20, administration module 40 and Executive Module 60.
In the multi-link application of heterogeneous network, the terminal has the K class professional, and every type of traffic table is shown S
k, professional S
kThe QoS demand in, the service rate demand schedule is shown R
k, k=1,2 ... K, then professional total transmission demand does
Minimum tolerance time delay is expressed as d
kBe connected with N the network that the terminal communicates this moment, and each connection is expressed as N
i, i=1,2 ... N, each network capacity is BW

The network average delay is used D
iExpression.Still have other M available network that does not connect in the network environment of living in of terminal this moment, each net list is shown N
j, j=1,2 ... M.The candidate network set is expressed as N
Candidate
One, multi-link transmittability changes; Comprise that the user moves the link-quality variation that causes; Network context information changes; The pairing offered load of a certain connection increases the weight of, the pairing network security risk increasing of a certain connection etc., and these factors all can cause multi-link transmittability to change;
Two, multi-service transmission demand changes, and comprises QoS of survice change, user preferences change, a service conversation end, a new business initiation etc.These factors all can cause multiple services transmission demand to change.
The result that these two types of triggering factors cause makes between total transmission demand of original business and the total transmittability of network unmatched situation to have taken place, thereby triggers multi-link management.When multiservice requirement increase or the reduction of multi-link ability, multi-link ability can not satisfy multiple services demand, needs to increase new network connection resource, guarantees the QoS of survice requirement; When multiservice requirement reduction or the increase of multi-link ability, can distribute better connection resource for multi-service, improve service feature and experience.
As shown in Figure 2, administration module 40 comprises that network determination module 41, priority determination module 42, weight are provided with module 43, sorting calculation module 44, algorithm data-base 45, matching module 46, Internet resources update module 47 and first judge module 48.Administration module 40 carries out network allocation according to network capacity information 90a and professional transmission demand information 90b to each business under the triggering of triggering signal 80.
Wherein, network determination module 41 is confirmed the candidate network set according to the total transmittability of network
and professional total transmission demand
.When
The time, existing multi-link transmittability satisfies total multi-service transmission demand, can utilize the current Internet resources that connected to be terminal multi-service service, current existing connection network N
Current={ N
i, i=1,2 ..., N} is the candidate network set, can be expressed as N
Candidate=N
Current, be each traffic assignments suitable network resource through the multi-link management of multi-service then.The existing user's bearer service that is connected to of preferential use this moment to avoid carrying out the process of new network discovery and register and authentication, is simplified multi-link operation, saves power consumption of terminal.When
The time, the existing total transmittability of network can not satisfy professional total transmission demand, then inquires about the available network situation that other do not connect, and (1≤m≤M) individual new network joins the candidate network set, thereby the candidate network set is expressed as N to select suitable m
Candidate={ N
l| N
l∈ N
Current∪ N
New, l=1,2 ..., N, N+1 ..., N+m}, wherein not connect collection of network be N to m
New={ N
j, j=1,2 ..., m, m≤M}.
New network selection is the needs that carry a business, and this business can be the new business that initiate at the terminal, can be one change owing to QoS or current quality of connection under the degradation reason new business that need shift.New network selection standard is at first to satisfy this professional qos requirement, because this business matches the possibility maximum of new network.For example, if this business is a real-time service, the network of then selecting not connect network average delay minimum in the available network joins the candidate network set; If this business is the business that a two-forty requires, the network of then selecting not connect transmission bandwidth maximum in the available network joins the candidate network set.
After selecting what a new network to add the candidate network set; Recomputate the professional transmittability of candidate network set, if satisfy
this moment then the candidate network set is confirmed; If do not satisfy; Then the standard according to the new network of above-mentioned selection continues to select a network to join the candidate network set, till satisfying
.But, be not that all not connection available networks are all joined the candidate network set, otherwise when the network ordering is shifted with business, can cause very macroreticular expense, destroy the availability of original connection.
Weight is provided with module 43 and stipulates each business setting weight with professional service quality according to the type of business.For real time business, because real time business has very strict requirement to time delay, parameters such as reply time delay and delay variation are provided with higher weight when weight is provided with, and other parameters are according to business need and user preferences relative set.For non-real-time service; Then more factors of considering price or bandwidth more; If professional higher to rate requirement, then for bandwidth parameter would be provided with higher weight, if the user hopes to obtain lower price; Then for price parameter is provided with higher weight, other parameters are according to business need and user preferences relative set.
Being provided with of weight can have multiple mode, should select suitable manner and calculate respective value with requiring according to actual conditions.Can weight be set by the user, promptly rule of thumb be one group of weight of each traffic assignments artificially; Also can be by the network settings weight, promptly according to the weight that is provided with of network statistics value for each business; Can also utilize AHP method (Analytic Hierarchy Process, analytic hierarchy process (AHP)), generate the relative importance matrix, draw one group of weight with EM (Eigenvector Method, characteristic vector method).
Present embodiment is that multi-service is provided with different weights, can seek the most suitable their network connection resource for multi-service.Because in multi-link applied environment, each network connection all has characteristic separately, is embodied on the static parameter of network carrying professional ability, like minimal time delay, maximum bandwidth, price for traffic etc.Meanwhile, the s own situation of network and service bearer situation change at any time, and causing the current business support ability of network is dynamic change, is embodied in such as parameters such as remaining bandwidths.After knowing these information of multiconnection network, each business need that is reflected in being provided with according to weight can correspondingly connect for each business finds the network that satisfies business need, thereby distributes multiconnection network resource better for multi-service.
If objective network is bigger for the lifting of service feature, cost that can the compensating network expense is then transferred to business on the objective network; If but objective network is less for the lifting of service feature, caused bigger network overhead on the contrary, think that then this professional the transfer there is no need.Because the selection of objective network is not necessarily optimum, but optimal, need to consider the compromise of service feature and network overhead, can not cause the very big network overhead and the wasting of resources because of excessively pursuing the optimum of performance.Therefore, a threshold value ζ can be set, when
The time, do not carry out business and shift; And work as
The time, business is transferred to the first ranking score S
T arg etCorresponding objective network.
Internet resources update module 47, after matching module 46 was the traffic assignments network, Internet resources update module 47 was calculated as the transmittability of the residue candidate network set behind the traffic assignments network.Promptly from the network capacity of existing connection, deducting is the transfer resource of traffic assignments.Network connects N
iOriginal transmittability be BW
i, distributing to transmission demand is R
kProfessional S
kAfter, network connects N
iThe renewal transmittability be BW '
i=BW
i-R
kThe renewal that network connects transmittability can guarantee that network connects the accuracy of situation, thereby carries out next round network sequencer procedure smoothly.
As shown in Figure 3, Executive Module 60 is transferred to the corresponding network that distributes according to allocation result 70 with each business, and it comprises second judge module 61, professional shift module 62, switches AM access module 63 and resource release module 64.
Switch AM access module 63, receive allocation result 70, according to the Internet resources that objective network is reserved in traffic assignments, switch and prepare and access authentication, carry out handoff procedure this moment, and setting up that new connection carries should business.
As shown in Figure 4, the multi-link management method of mobile communication multi-service of the embodiment of the invention may further comprise the steps:
Step 1 triggers multi-link management;
Step 3 is given each traffic assignments network;
Wherein, step 1 is specially the multi-link management of change triggers according to the total transmittability of network
and professional total transmission demand
.
As shown in Figure 5, confirm in the step 2 that the candidate network set specifically comprises:
Step 2c inquires about the available network that other do not connect, and selects m new network N at least
jJoin the candidate network set, form new candidate network set N
Candidate={ N

New, l=1,2 ..., N, N+1 ..., N+m};
Step 2e, new candidate network set is confirmed.
Preferably, according to the transmittability of each network, with disabled network or the little network of transmittability in the set of new network replacement candidate network.When the network capacity of new selection is fine,, can considers to remove in original connection disabled network and connect or replace the relatively poor network of transmittability in original connection because new network confirmed and must add the candidate network set.But still the transmittability that need satisfy all-network in the candidate network set can satisfy the multi-service transmission demand, i.e.
Comprised before in the step 3 and confirm each professional priority, be specially: type and professional service quality regulation according to business are confirmed each professional priority.
As shown in Figure 6, step 3 specifically comprises:
Step 3c gives each traffic assignments network according to ranking results;
Whether all step 3e judges each business distribution network, if then execution in step 4; If, then do not return step 3b.
Wherein, among the step 3a, can be each business setting weight according to user's needs or network statistics value; Or utilize analytic hierarchy process (AHP) to generate the relative importance matrix, draw each professional weight with the characteristic vector method.
Carry out in the sequencer procedure for each professional candidate network among the step 3b, real-time or type real time business for all preferentially select for use an existing network to connect transport service, and network performance should satisfy D
i≤d
k, D
iBe the minimal time delay of network, it is responsive to delay requirement that its reason is this type of business, handles and want fast, and therefore not considering multi-linkly provides service manner for single business.And for non-real-time service (priority of network ordering is minimum); Then possibly exist many networks to be connected to the situation of a business service; Its core concept is to utilize remaining bandwidth to be business service; It is for example professional for ftp that network performance should satisfy
; Can be only with the bandwidth of candidate network from big to small (or on cost from low to high) sort; Use corresponding network to connect if maximum bandwidth can satisfy, if can not just add time greatly, the rest may be inferred finds can provide a plurality of networks of this business to connect.
Among the step 3b; Can also be according to the actual conditions of network and user's business need; With simple weighted and method (Simple Additive Weighting is called for short SAW), approach ideal solution ranking method, cost function method or weighting Markov Chain Method each business carried out the candidate network ordering.
Step 3c can comprise: establish ranking score the highest be the first ranking score S
T arg et, its corresponding candidate network is an objective network, the ranking score of professional current network is the second ranking score S
Current, work as S
T arg et=S
CurrentThe time, the first ranking score S
T arg etCorresponding objective network is professional current network, does not carry out business and shifts; Work as S
T arg et＞S
CurrentThe time, i.e. the first ranking score S
T arg etThe service feature of corresponding objective network is superior to the service feature of professional current network, and business is transferred to the first ranking score S
T arg etCorresponding objective network.
If objective network is bigger for the lifting of service feature, cost that can the compensating network expense is then transferred to business on the objective network; If but objective network is less for the lifting of service feature, caused bigger network overhead on the contrary, think that then this professional the transfer there is no need.Because the selection of objective network is not necessarily optimum, but optimal, need to consider the compromise of service feature and network overhead, can not cause the very big network overhead and the wasting of resources because of excessively pursuing the optimum of performance.Therefore; More excellent; Step 3c can also comprise: a threshold value ζ is set; During as
