Abstract
The invention discloses a network link selecting method distinguishing an upstream data stream from a downstream data stream, and belongs to the technical field of wireless communications. The network link selecting method includes that a network selecting server obtains various medium streams of the upstream and downstream data streams according to business requirements of users, and matches a device required by business with the best network link according to network environment parameters and quality of service (QoS) information of the various medium streams. By means of the network link selecting method, the business requirements are divided into a plurality of medium streams by aid of differences of transmission rates of the upstream and downstream data stream links, uploading of the various medium streams is finished by means of the upstream or downstream data stream link with the maximum rate, and therefore selecting efficiency of a converged network is improved.
Description
Technical field
The invention discloses a kind of network link system of selection of differentiating uplink and downlink data flow, belong to technical field of wireless communication.
Background technology
The network architecture system that merges of future generation be comprise the wireless network of 2G (GSM), 3G (UMTS), LTE, WLAN, WiMax etc. and comprise xDSL, Broadcasting Cable Network etc. cable network and deposit, overlapping covering and intercommunication.Collaborative single mode or the multi-mode terminal equipment that is utilization to heterogeneous networks in terminal, enabling is providing professional continuity and the professional whole perhaps concertedness between the different piece under the environment of the network integration.
Traditional network selecting mode is the quality good or not of the heterogeneous networks that can insert according to subscriber equipment, selects the Access Network of a network of optimal quality as this equipment.What this method was directed against is present situation separate between the existing network, yet in UNE of future generation, it is complicated that situation will become.
To occur cross interconnectedly between different Access Networks and the different core network, for the utilance that improves Access Network is avoided overlapping investment, different core net can shared a part of access network equipment.Each core network and access network have characteristics separately, like the difference of rate, network maximum throughput, uplink rate and downlink rate etc.The uplink downlink difference of Access Network particularly: the network that upstream rate is big is more suitable for transmitting the up Media Stream part in the session, and the network that downstream rate is big is more suitable for transmitting the part of downlink media stream.
The network-termination device that the user had will increase greatly, and on the one hand new network-termination device continues to bring out, and more original on the other hand equipment that can not access network also will possess the ability of access network.Distinct device advantageous feature separately is distinct more, and the capacity variance that represents of different medium compositions is increased, and becomes a kind of business realizing pattern for a plurality of equipment collaboration work of business experience that obtain the best like this.
The more and more development of abundant multimedia service; People are increased the demand of Rich Media greatly, yet only rely on network of an equipment, can not satisfy user's demand fully; In order to make business reach the best effect that appears; To use a plurality of equipment simultaneously, each equipment is responsible for the heterogeneity in the service conversation, and equipment room relies on synchronizing function to realize the collaborative of session.
Thereby propose a kind ofly to be applicable to that the multi-terminal equipment in UNE selects the method for access network that the service of higher user experience will be provided for the user fast.
Summary of the invention
Technical problem to be solved by this invention is to the deficiency of above-mentioned background technology, and a kind of network link system of selection of differentiating uplink and downlink data flow is provided.
The present invention adopts following technical scheme for realizing the foregoing invention purpose:

Step 2, user's container are sent the request of network selecting to the network selecting server;
Step 3, the network selecting server obtains the different medium compositions in the up or downstream data flow in the business according to the customer service demand;
Step 4, network selecting server are given professional equipment needed thereby configuration optimum network link;
Step 5, user's container is initiated service call request to application server, and said service requesting information comprises: professional equipment needed thereby information and optimum network link information;
Step 6, application server are replied acknowledge message and are given user's container satisfying the business of returning under the condition of service call request;
Step 7, user's container sends switching command to professional equipment needed thereby, and professional equipment needed thereby switches to best access network link;
Step 8, the best access network that application server access service equipment needed thereby is corresponding, professional equipment needed thereby pass through best access network to the application server media stream.
In the network link system of selection of said differentiating uplink and downlink data flow, step 4 specifically comprises the steps:
Step 4-1 divides required network QoS ability according to different medium compositions, but the QoS information, facility information, the network environment information that mate different medium compositions obtain the corresponding relation of professional equipment needed thereby and access network;
Step 4-2, but the corresponding relation of professional equipment needed thereby and access network is fed back to user's container, but user's container is controlled professional equipment needed thereby and is connected to access network;
Step 4-3 is satisfying under the situation of business demand, is that prerequisite is calculated from application server to the optimum network link the professional equipment needed thereby with the minimal network Resources Consumption, and then the selection result with the optimum network link feeds back to user's container.
The present invention adopts technique scheme; Have following beneficial effect: this method utilization difference of data flow link transmission speed up and down is divided into some medium compositions with business demand; Utilize the up of maximum rate or downstream data flow link to accomplish uploading of each medium composition respectively, improved the co-operating overall utility in a plurality of terminals of UNE and user side.
