Description
Technical field
The present invention relates to the communications field, in particular to a kind of access service switching method and system.
Background technology
Micro-wave access to global intercommunication technology (Worldwide Interoperability forMicrowave Access abbreviates WiMAX as) is a kind of broadband wireless access standard, and this standard provides towards the high speed of the Internet to connect based on 802.16 agreements.
The WiMAX system for example can carry: multiple business such as voice, video, HTTP and E-mail since each business to service quality require differently, carry different business datums so the different Business Stream of WiMAX network using is same portable terminal.Wherein, Business Stream is divided according to grouping information such as source address, destination address, port numbers and protocol numbers, and be that each Business Stream specifies a service quality (Quality of Service abbreviates QoS as) parameter, so that provide corresponding service quality for different business.In addition, system also sets a traffic stream identifier (Service Flow Identification abbreviates SFID as) for each Business Stream, is used to indicate this Business Stream and corresponding qos parameter.
In actual applications, can carry out operations such as establishment, approval, activation, modification, deletion at Business Stream.In current Business Stream constructive process, if the access control of service flow management module is not passed through, that is, current interface-free resources situation can not satisfy creates the traffic request resource, then has two kinds of response results:
(1) if comprises resource degradation sign indicating number (Reduced Resource Code in the Business Stream request to create (resource reservation request), abbreviate RRC as) parameter, Business Stream is normally created and the service flow management module will comprise the QoS Parameters attribute that the current Radio Resource situation that can provide is provided to Business Stream request to create entity (being the service flow authorization service point herein) response.
(2) if do not comprise this attribute in the Business Stream request to create, this request will be rejected, and Business Stream is created failure.
By this mode that the RRC attribute is provided in request, under the rare situation of Radio Resource, for the user provides a kind of possible resource negotiation processing mode.
The WiMAX network is supported for its user provides complete access business network to switch.Fig. 1 is the flow chart of access business network hand-off process of the prior art.As shown in Figure 1, this flow process may further comprise the steps:
Step 1, the handoff functionality of WiMAX service network switches affairs by sending handoff request message (HO_Req) initial network;
Step 2 is to 3, and WiMAX junction network handoff functionality is according to the handoff request message that receives from the WiMAX service network, and to this handoff request of target WiMAX network trunk, this handoff request may mail to one or more objective networks; In this flow process 2 objective networks, that is, and WiMAX objective network 1 and WiMAX objective network 2;
Step 4 is to 5, and WiMAX objective network 1 and WiMAX objective network 2 switch this handoff request of corresponding (HO_Rsp) message response by sending;
Step 6, the WiMAX junction network is merged into a HO_Rsp message with all HO_Rsp message that receive, and responds the service network to WiMAX;
Step 7, WiMAX service network select unique objective network (WiMAX objective network 2) to confirm this time resource response, send switch acknowledgment message to junction network;
Step 8, junction network is to this switch acknowledgment message of unique selected objective network (WiMAX objective network 2) relaying.
In above-mentioned access business network switching flow, if the QoS demand in this handoff request can not be met at least one objective network in all possible WiMAX objective network, then this handoff request can be directly by all objective network refusals, cause the user can't land objective network, reduced user experience.

In actual applications, the handoff request message that this handoff functionality sent can be carried RRC according to user's needs, if carry RRC then represent that the user allows can not satisfy under the situation of handoff request in the objective network interface-free resources in handoff procedure, to the processing of demoting of user applies resource;
Step S304 to S306, WiMAX junction network handoff functionality is according to the handoff request message that receives from service network, to target WiMAX network 1 and target WiMAX network 2 these handoff request of difference relaying, this handoff request may mail to one or more objective networks; In the present embodiment, the quantity of objective network is exemplary illustration, and the quantity of objective network is not limited only to this in actual applications;
Step S308 to S310, the access service network of WiMAX objective network 1 and WiMAX objective network 2 (Access Service Network abbreviates ASN as) send switching response message (HO_Rsp) to the WiMAX junction network respectively and respond this handoff request;
Particularly, target ASN network receives handoff request message, if wherein comprise resource degradation sign indicating number information, then this target ASN network should comprise resource degradation sign indicating number in the Business Stream request to create of follow-up initiation, so that at service flow management module (Service FlowManagement, abbreviate SFM as) admit control not by (promptly, current interface-free resources situation can not satisfy creates the traffic request resource) time can be to the Business Stream processing of demoting, rather than directly refuse this Business Stream request to create;
The resource degradation has taken place in the process if pre-create at the Business Stream of target ASN network, relaying ASN network/service ASN network then requires to comprise in the switching response message (HO_Rsp) in its transmission the attribute of this resource degradation incident of a sign, so that can be known this incident; In addition, can also carry actual in this switching response message is the resource of the traffic flow assignment of these degradations, and attributes of these sign actual allocated resources are optionally to realize parameter (step S304 to S310 is corresponding to the step S204 among Fig. 2);
Step S312, the WiMAX junction network is merged into a HO_Rsp message response to the WiMAX service network with all HO_Rsp message that receive, and the WiMAX service network receives this response message.These HO_Rsp message are the response message described in step S308 and the S310, wherein may comprise resource degradation event identifier and description;
Step S314, WiMAX service network select unique objective network to confirm this time resource response, send switch acknowledgment message to junction network.When carrying out the objective network selection, should preferentially select those objective networks that resource degradation does not take place (that is the objective network that, does not comprise resource degradation event identifier in the HO_Rsp message of transmission) as switching target; Under the situation that does not have the objective network that the resource degradation does not take place, then select to take place the objective network of resource degradation as switching target;
Step S316, WiMAX junction network are to unique selected objective network (for example: this switch acknowledgment message of relaying (step S312 to S316 is corresponding to the step S206 among Fig. 2) objective network 2).
The foregoing description has provided the preferred process flow process according to the embodiment of the invention, by this embodiment, can not satisfy under the situation of creating the traffic request resource in current interface-free resources situation,, rather than refuse this Business Stream request to create the Business Stream processing of demoting; Can not produce the QoS that all objective networks all can not satisfy this handoff request and cause refusing this time handoff request business, thereby can satisfy user's handoff request demand.
