Description

The application subclass machinery of consultation that accesses terminal and initiate
Technical field
The present invention relates to field of wireless communication, specifically, relate to banising of initiation of a kind of accessing terminal (Access Terminal is called for short AT) and put machinery of consultation.
Background technology
CDMA2000 1xEVDO system as the evolution of 3G (Third Generation) Moblie technology CDMA2000, is mainly used to provide high-speed data transmission service.In CDMA2000 1xEVDO system, AT and Access Network (Access Network, be called for short AN) connect set up before, need negotiate a cover and banish and put, to support the upper-layer packet application service.
The negotiation of stream is divided into the stream that stream is consulted and AN initiates two stages of negotiation that AT initiates.In the stream negotiation request message that AT initiates, carrying the grouping application service type that AT supports and wishes to use.The stream that AN initiates is consulted then according to the ability of AT, determines the grouping application service type that AN wants to use and AT can support.
Fig. 1 is the stream negotiations process signal that AT initiates in the prior art, includes following steps:
Step 101, AN sends a session configuration protocol (Session Control Protocol is called for short SCP) to AT and starts (SCPConfigStart) message, and expression AT can begin to initiate negotiation phase;
Step 102, AT sends SCP request (SCPConfigRequest) message to AN, after AT receives that SCP starts (SCPConfigStart) message, can be to AN feedback SCP request (SCPConfigRequest) message, in this SCP request message, AT carries the application subclass attribute (ATSupportedApplicationSubType Attribute) that oneself can support, by this complex properties, AN can have one clearly to understand the ability of AT, so that correctly constructing to banish in the back, AN puts request message, application subclass attribute wherein, its content comprise the sign (ID) of respectively using subclass;
Step 103, AN makes judgement according to the tenability of self to the application subclass that AT provides, and sees whether AN itself supports, and send SCP response (SCPConfigResponse) message to AT according to judged result, wherein carry the application subclass attribute that both sides support;
Step 104, AT according to the application subclass that both sides support, banishs the request of putting (StreamConfigRequest) message to the AN transmission after consulting to finish at the application subclass with AN, be illustrated between AT and the AN, consult to be tied to the application subclass on each stream; It is follow-up to using the first step that subclass is consulted, have only consult to determine application subclass that each stream bound by stream after, just know follow-uply on each stream, use which application subclass, and need use subclass to which and carry out attribute negotiation;
Step 105, AN sends to banish to AT and puts response (StreamConfigResponse) message, the response of putting request message recipient convection current configuration request message is banishd in expression, banishs to put the request message recipient and can represent to receive certain cover and banish and put, and perhaps refuses all and banishs and put; Afterwards, carry out the process that AT initiates other protocol negotiations of negotiation phase;
Step 106, after all protocol negotiation processes that AT initiates to consult were finished, AT sent a SCP to AN and finishes (SCPConfigComplete) message, and expression AT initiates negotiation phase and finishes, and enters AN and initiates negotiation phase.
AT and AN can consult many covers and consult attribute, are referred to as the negotiation of many cover Personality.In the negotiation of every cover Personality, all need independent convection current configuration to hold consultation again.Put in the negotiation request message banising of AT initiation, will carry the value of a cover stream attribute at least, carry out selective reception for AN, every cover is banishd and is put the application subclass that attribute can be filled in 4 streams, the following example that is:
attribute_id＝0 (0 x 0) (StreamConfiguration)
num_recs＝2 (0 x 2)
stream_config[0]
value_id＝0 (0 x 0)
stream0_app＝0 (0 x 0) (Default Signaling Application)
stream1_app＝65535 (0 x ffff) (Stream not used)
stream2_app＝5 (0 x 5) (Multiflow Packet Application for Service
Network)
stream3_app＝65535 (0 x ffff) (Stream not used)
stream_config[1]
value_id＝1 (0 x 1)
stream0_app＝0 (0 x 0) (Default Signaling Application)
stream1_app＝65535 (0 x ffff) (Stream not used)
stream2_app＝2 (0 x 2)(Default Pkt App Bound to Service Network)
stream3_app＝65535 (0 x ffff) (Stream not used)
Wherein num_recs is illustrated in banising of carrying in the message and puts tricks, and expression carries the negotiation of 2 cover Personality in this example; And ValueID equal 0 banish that to put attribute be that AT recommend to use banising of (being that aforesaid hope is used) to put attribute.
The application subclass attribute (ATSupportedApplicationSubtypes Attribute) that AT supports is a complex properties, can not selection portion divides for its AN to receive.If the AT of certain cover Personality initiates negotiation phase, emerging AT proposed an early version AN the new application subclass that can not receive, AN this cover that can only refuse to contain this new application subclass is banishd and is put so, and can not partly receive all the other this early version AN of banising in putting the application subclass that can receive, AT can not just banish the application subclass that other AN in putting can receive further and hold consultation.
After entering the negotiation phase of AN initiation, though can negotiate AN and the common application subclass of supporting of AT both sides, AN does not know AT wishes what the application subclass of using is most, and can only initiate the negotiation of stream attribute by the configuration of oneself.Therefore, AT wishes that the application subclass of using may all have no chance to consult forever, also just has no idea to use.
Summary of the invention

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Consider AT why can not be exactly to AN initiate own wish banish the agreement of putting request message and obtaining AN, be to come from AT not know which application subclass AN supports, always according to oneself ability and wish, the application subclass that selection will be consulted.Therefore, can not know under the situation of AN ability to avoid AT, initiate to have the request of putting of banising that AN does not support to use subclass rashly at there not being suitable mechanism to allow AT know that the flow process of the application subclass that AN supports improves at present.For this problem, can before initiate to banish the request of putting, AT allow it know the tenability of AN, and reintroduce the request of putting of banising according to both sides' tenability.
In addition, consider that AN only contains unsupported some or several application subclass because banish in putting, just refused this cover banish put in the negotiation of all the other application subclasses that can receive, also can not selectivity receive this defective of application subclass of banising in putting at this AN, the application subclass that AN can be received in can the convection current configuration is carried out selectivity and is received.
Before initiating to banish the request of putting, AT allow it know the tenability of AN for above-mentioned, in one embodiment of the present of invention, be which a kind of AN of expression of structure supports use the ANSupportedApplicationSubtype Attribute of subclass (the application subclass attribute that AN supports), come tenability to AT notice AN.Table 1 shows the definition of the application subclass attribute of AN support, represent its byte length (Length) with 8 bits (bits), its attribute-bit of 16 byte representations (AttributeID), the default value of configuration attribute (Default) is N/A, the function of the application subclass attribute that this AN supports is similar to the application subclass attribute that AT supports to the AT of the tenability of AN notice own.
The application subclass attribute definition that table 1, AN support
Field Length(bits) Default
Length 8 N/A
AttributeID 16 N/A
ValueID 8 N/A
NumAppSubType 8 0
ApplicationSubtype 16 N/A
Length wherein represents byte length, AttributeID representation attribute ID wherein.
ValueID wherein represents the value sign of complex properties., when selecting the value of certain complex properties, must in response message, carry the sign of selected complex properties value, just the ValueID here.The value sign of complex properties is unique in a negotiation message.
NumAppSubType wherein, the quantity of application subclass in the identity property tabulation is to make things convenient for encoding and decoding.
ApplicationSubtype wherein represents to use the sign of subclass in agreement.
The AttributeID that defines ANSupportedApplicationSubType Attribute simultaneously is still untapped attribute-bit in the current sessions configuration protocol, for example 0 x 1002.
Present embodiment is finished AN by session configuration protocol response message itself tenability is notified to AT.Behind the application subclass attribute that has increased the AN support, session configuration protocol response message is defined as follows:
Session configuration protocol response message behind the application subclass attribute that table 2, increase AN support
Field Length(bits)
MessageID 8
TransactionID 8
AttributeRecord Attribute dependent
ANSupportedApplicationSubtype Attribute Attribute dependent
MessageID wherein represents message id, and TransactionID wherein represents to handle ID.
AttributeRecord wherein is in the session configuration protocol response message, the attribute record field that should fill in according to current agreement.
ANSupportedApplicationSubtype Attribute wherein is the newly-increased attribute of the inventive method.According to summary of the invention, this field is in session configuration protocol response message, and the number of times of appearance may be 0 time or 1 time.
As shown in Figure 2, the flow process for the embodiment of the invention comprises the steps:
Step 201, AT receives after SCPConfigStart (startup of the session configuration protocol) message, be defined in SCPConfigRequest (request of the session configuration protocol) message according to agreement, carry ATSupportedApplicationSubType Attribute, comprised the sign of the application subclass that all AT support;
Step 202, AN resolves also selective reception or does not receive the application subclass attribute that AT supports according to the tenability of oneself:
If AN finds the application subclass that AT supports, AN can both receive, and in giving SCPConfigResponse (response of the session configuration protocol) message of AT, just notifies AT to receive the application subclass attribute that AT supports so;
If AN finds in the application subclass attribute of AT support, have the unsupported application subclass of AN, AN is just in session configuration protocol response message so, the application subclass that refusal AT supports, and in this session configuration protocol response message, carry ANSupportedApplicationSubTypeAttribute (the application subclass attribute that AN supports);
The application subclass attribute that AN supports, the actual configuration form in message is exemplified below:
attribute_id＝4098 (0 x 1002) (ANSupportedApplicationSubtypes
Attribute)
num_recs＝1 (0 x 1)
at_supported_app_subtype_attrib[0]
value_id＝0 (0 x 0)
num_app_subtypes＝3 (0 x 3)
app_subtypes[0]＝1 (0x1) (Default Packet Application bound to the
radio network)
app_subtypes[1]＝2 (0x2) (Default Packet Application bound to the
service network)
app_subtypes[3]＝5 (0x5)(Multi-Flow Packet Application bound to the
service network)；
Step 203, after AT receives SCPConfigResponse message, just know whether AN receives the application subclass attribute of its proposition:
If AN receives the application subclass attribute that AT supports, the application subclass of then utilizing both sides wherein all to support is carried out follow-up flow process;
If AN does not receive the application subclass attribute that AT supports, AT parses the application subclass attribute that AN supports in session configuration protocol response message so, therefrom learns in follow-up stream is consulted, and which should have use subclass can participate in consulting.
If AT knows that AN does not receive the application subclass attribute that AT supports in the step 203, and can not parse the application subclass attribute that AN supports yet, an optional method is, AT sends session close message (SessionClose), in the cause field of this session close message, fill in the protocol configuration failure information, notice AN session configuration protocol configuration failure.
The value of the application subclass attribute that AN is supported, propose optional method a: AN and only fill in the application subclass that is included among the ATSupportedApplicationSubType Attribute in this attribute, the application subclass that will not exceed this scope is filled up among the ANSupportedApplicationSubTypeAttribute.As the another one optional method, AN here also can be with going up whole application subclasses of oneself supporting, and it is that part of to comprise that AT proposes.AT just can know the application subclass that oneself proposes like this, and which is that AN can support, which can not be supported.
Like this, AT just can not construct banising that AN can not support and put attribute when follow-up structure StreamConfigRequest message.Thereby avoided AN because do not support certain to use subclass, and refused the situation of whole stream attribute group.
In an alternative embodiment of the invention, construct a tenability and consult (capabilitynegotiation) reciprocal process, by this reciprocal process, AT and AN notify own to using the tenability of subclass mutually to the other side.This capability negotiation comprises but does not terminate in the application subclass that both sides support.Definition realizes that this reciprocal process handling capacity negotiation message realizes, and AT can hold consultation with regard to the ability of the two common support at least with AN both sides' handling capacity negotiation message.At least put before request message initiates banising the opportunity that capability negotiation message is initiated.Such as: the initiator carries all application subclasses in message for requesting capability negotiation, the recipient is known initiator's ability by it.If the recipient receives initiator's request fully, then in response message of capability negotiation, express the request that receives the initiator; If the recipient can only partly support the capability requests that the initiator proposes, then the recipient constructs the application subclass attribute that the initiator supports according to tenability of oneself and initiator's tenability, and handling capacity negotiate response message is issued the initiator.
Fig. 3 shows the step of present embodiment, comprising:
Step 301, AN sends SCPConfigStart (startup of session configuration protocol) message to AT, and expression AT can begin to initiate negotiation phase;
Step 302, AT initiates a Capabilitynegotiation Request (capability negotiation request) message to AN, carry ATSupportedAppSubType Attribute (the application subclass attribute that AT supports) in this message for requesting capability negotiation, the application subclass of itself supporting is notified to AN;
Step 303, after AN receives message for requesting capability negotiation, tenability according to self is judged the application subclass that AT proposes, if the application subclass that AT proposes is all within the support scope of AN, then receive the application subclass attribute that AT supports, otherwise the application subclass attribute that structure AN supports is according to a judged result feedback Capabilitynegotiation Response (capability negotiation response) message; If also promptly AN receives the application subclass attribute that AT supports, then comprise the application subclass that AN receives in this response message of capability negotiation, expression receives the application subclass attribute that AT supports, otherwise, contain the application subclass attribute that AN that AN constructs supports in this response message of capability negotiation, so that AT puts in the request message banising of follow-up initiation, use correct application subclass;
Step 304, AT receives after the response message of capability negotiation, according to the tenability of and AN own, sends session configuration protocol request message to AN, wherein carries the application subclass attribute that both sides support.
The 3rd embodiment of the present invention is that AN informs the application subclass that oneself is supported to AT on one's own initiative.When initiating to consult, AN initiatively carries all application subclasses of being supported on a certain the message of consulting, and allows AT have an approach to know which AN can support use subclass, can not support which to use subclass.Adopt the application subclass attribute of the AN support that proposes in the above-mentioned first method for this reason.Like this, before AT initiated to banish the request of putting, just having ready conditions allowed AT know how to construct banising that AN can support to put attribute.
Carry the opportunity of the application subclass attribute of AN support, can be in article one SCPConfigStart message that AN initiates to consult, perhaps in article one SCPConfigResponse message that AN participates in consulting to AT.These message are sending and receive on the sequential, all before AT initiates the StreamConfigRequest message of negotiation phase.Which AT supports use subclass with regard to known road AN when initiating StreamConfigRequest message like this, thereby guaranteed to put in the request message banising of sending of AT, and it is banishd to put and can not contain the application subclass that AN can not handle.Table 3 shows in SCPConfigStart message increases the application subclass attribute that AN supports:
Table 3, increase the application subclass attribute that AN supports in SCPConfigStart message
Field Length(bits)
MessageID 8
ANSupportedApplicationSubtype Attribute Attribute dependent
MessageID wherein represents message id.
The thinking of this method is to allow AN inform the application subclass that AT oneself supports on one's own initiative, does not need AT that it is responded.Therefore, regulation AT puts in the request message banising of follow-up AT initiation after handling this attribute, support to use the ability of subclass according to AN, and structure is banishd and put attribute.
More than these three embodiment all be according to prior art, before AT initiates to banish the request of putting, allow it know the tenability of AN, and reintroduce according to both sides' tenability and to banish the request of putting this carries out improved on the one hand.In fact, AT also can consider to revise the organizational form of Stream configuration request message, the negotiation mode of convection current in the existing protocol is banishd and put group from consulting one, be revised as the application subclass of single stream is held consultation, facilitate judgement and the selection of recipient AN like this.And each stream is all used a simple attributes to tabulate to organize, and as shown in table 4 such as all adopting independent attribute list to represent, AN just can carry out independent negotiation like this.In agreement, need all to distribute a untapped attribute-bit (Attribute ID) for each stream.
Table 4, each stream attribute adopt the mode of simple attributes tabulation to list
Field Length(bits) Default
Length 8 N/A
AttributeID 16 N/A
ApplicationSubtype 16 N/A
Length wherein represents length, AttributeID representation attribute sign.
ApplicationSubtype wherein is the codomain of a simple attributes, and its value is to use the sign of subclass in agreement.
For in the easy configuration attribute list of session configuration protocol, increase the stream definition, need to revise existing protocol.Existing protocol is consulted need make an amendment agreement not at the row of session protocol negotiation about the application subclass of 4 stream protocols.
Table 5, easy configuration attribute list
Figure A200710163763D00141
As shown in table 5, Attribute wherein represents the hexadecimal span of NN among the AttributeID (not comprising 0 x, 14,0 x, 15,0 x 16, and 0 x 17); The value of 0 x, 0000 expression default protocol subclass wherein, 0 x fffe represents to connect firmly the value of agreement subclass, 0 x 0000-0 x fffd, the value of 0 x ffff presentation protocol subclass.At first, need " excluding values0 x 14,0 x 15,0 x 16, and 0 x 17. that describe in the Attribute item in the releasing table 5 26" the pairing function restriction of content; Secondly, increase description: for stream protocol, the default value of its configuration attribute is N/A, and is as shown in table 6.Its configuration attribute should be the application subclass agreement ID that is tied on the stream.
Easy configuration attribute list after table 6, the modification agreement
Figure A200710163763D00151
AN puies forward the application subclass of recommending to each stream selective reception AT after receiving that banising of AT initiation put request message individually.If AT has the unsupported application subclass of AN in the configuration request message of certain stream, AN just can only refuse the application subclass of this stream so, but other stream then still can selective reception.
Existing protocol is being consulted to banish when putting, and always puts structure and uses a subclass for banising, if AT supports multiple application subclass, AT must be combined into many groups voluntarily and use subclasses and select for AN.This method that the present invention proposes has then been broken to banish and has been put the restriction that must hold consultation by the mode of using the subclass group, supports each stream is judged separately, thereby has improved the stream configuration flexibility.
At AN initiation negotiation phase, according to both sides' ability, banish put negotiation again by the continuation initiation for AN, is that remaining stream consults to use subclass, and perhaps AN just in the application subclass of certain stream oneself hope use, consults with AT.
If AT propose certain flow it and use subclass and can not be received by AN, follow-up AN does not use subclass for this stream binding yet, this does not also mean that and will consult failure or negotiation does not reach best effects.Because the stream that does not have to bind may be not necessarily.Such as, in 4 streams of agreement regulation, stream 0 has been bound AT and AN respectively to stream 2 and has been wished the application subclass used most, and they comprise: default signaling application subclass, serve the application subclass of application subclass, service and the service network (Service Network) of wireless network (Radio Network).Even if flow 3 not bindings whatever so, also can normally not carry out by traffic affecting.
Below come to set forth more meticulously this method by an Application Example:
For example, corresponding stream 2, AT are sent following configuration attribute banising to put in the request message:
attribute_id＝22 (0 x 16) (Stream2 Attribute)
num_recs＝2 (0 x 2)
protocol_subtype[0]＝2 (0 x 2) (Default Pkt App Bound to Service
Network)
protocol_subtype[1]＝5 (0 x 5) (Multiflow Packet Applicationfor
Service Network)
In Stream2 Attribute, AT has proposed 2 selectable application subclasses.At this moment, AN can be according to the ability of self, and uses the selection principles of subclass down with realizing relevant many cover personality, selects certain application subclass bandage to Stream2.
Still with reference to figure 1, AN fills out the application subclass of Stream2 bandage banising to put and passes to AT in the response message in the step 105, and message format is exemplified below:
attribute_id＝22 (0x16) (Stream2Attribute)
protocol_subtype[0]＝2 (0x2) (Default PktApp Bound to Service
Network)
This expression AN is tied to Default Pkt App Bound to Service Network on the stream 2.
For the stream negotiations process of other Stream similarly.Initiate negotiation phase at AN, request message is put in banising that AN initiates, banising of AT response put response message, the also similar with it processing of their structure.
In sum, the present invention is by transforming prior art, allow AT before the configuring request of initiating concrete agreement, the protocol attribute of just knowing AN and being supported, perhaps can allow AN optionally receive the application subclass that it can be supported, AT just can constitute the protocol configuration property set that to be fit to AN so, and can not appear in the concrete protocol configuration request that AT initiates, contain AN the situation of supported protocol attribute not.AT and AN just are connected when setting up required some attribute and holding consultation, and just can avoid under existing protocol defines the indeterminate property that the negotiation message that is occurred is constructed according to the inventive method.
