Abstract
A method, apparatus, and system for negotiating a session between an access terminal (AT) and an access network (AN) that can simplify a repeated negotiation procedure when the session is configured/updated/deleted between the AT and the AN. The AN performs protocol-by-protocol negotiations with the AT for a session configuration. The AN sends, to the AT, a soft configuration complete message including a continue bit indicating if another session configuration is added. When all session configurations have been completed, the AN and the AT determine if a session configuration currently in use has been changed. If the session configuration in use has not been changed, the AT and the AN maintain a physical channel. Moreover, the AN sends information indicating if a specific session configuration is applied after session configuration negotiation is completed.
Description
Technical field
The present invention relates generally to be used for mobile communication system access terminal and access network between negotiation method, equipment and system.More specifically, the present invention relates to be used for access terminal and access network between the method, apparatus and system of consulting session, its can be reduced at access terminal and access network between the negotiations process of repetition during configuration/renewal/deletion session.
Background technology
Along with the fast development of the communication technology, mobile communications network provides the high data rate service of the multimedia service that is used to allow to be used for Email, static and mobile image etc. and traditional voice service.Be used to support that traditional mobile communication system of high data rate service comprises CDMA 2000 1x (CDMA2000 1x), 1x Evolution Data Only (1xEV-DO), 1x Evolution for Data﹠amp; Voice (1xEV-DV), async-generic mobile communication system (UMTS) etc.These mobile communication system have the channel architecture that is used for the high data rate transmission.
Among these mobile communication system, the High Rate Packet Data system of the data communication enhancing of IS-2000 system is advised, is used for by the 1xEV-DO system by third generation collaborative project 2 (3GPP2) by the 1xEV-DO system.At first, will the channel architecture of 1xEV-DO system be described briefly.
In the 1xEV-DO system, the positive physical channel that is sent to access terminal (AT) from access network (AN) comprises pilot channel, forward medium access control (MAC) channel, forward traffic channel and forward control Traffic Channel.With time division multiplexing (TDM) scheme, the positive physical channel is sent to AT.Forward traffic channel carries user data packets by the positive physical channel.By transmitting the user data packets of control messages and encapsulation with the corresponding forward control channel of common signal channel.Use forward MAC channel to transmit reverse rate control information, power control information etc.
In the 1xEV-DO system, be sent to the reverse physical channels of AN and the difference of positive physical channel is from AT, reverse physical channels has different identification codes based on AT one by one.The backward channel of AT is pilot channel, reverse traffic channel, reverse data rate control (DRC) channel, reverse rate indicator (RRI) channel, access channel etc. one by one.By the reverse traffic channel carries user data packets.Before connecting Traffic Channel, when being sent to AN with message or flow, uses AT access channel.The DRC channel is used for notifying AT can receive the highest transfer rate of data to AN.The RRI channel is used for providing the notice that transmits the transfer rate of data by reverse traffic channel.
On the other hand, in traditional IS-2000 system, use Electronic Serial Number (ESN) to identify AT.Yet the 1xEV-DO system distributes unicast access terminal identifier symbol (UATI) rather than ESN to each AT, and uses UATI to identify each AT.Overlay area (that is to say each subnet) definition UATI to same controller (Packet Control Function (PCF) entity or radio network controller (RNC)).Dispose UATI by subnet identifier part and AT identifier portion.When the 1xEV-DO terminal when a subnet moves to another, distribute the new UATI that disposes by new subnet identifier.
Thereby the 1xEV-DO terminal must at first be assigned with and the corresponding UATI of AT identifier, with the systems exchange data.Be used for by physical layer channel to AN transmit data and from AN receive data method, be used for the MAC layer be provided with transport-type with data format in case transmit data method, be used for articulamentum keep the calling of foundation or under idle condition, transmit and receive data method, be used to separate, recombinate (rearrange) and the method that for example transmits the higher-layer data that control protocol/Internet Protocol (TCP/IP) divides into groups of retransferring etc., the AT that receives UATI carries out the processing of the parameter of protocol system one by one that is used to consult every layer, with the AN swap data.
In the processing of the negotiation that is used for system parameters, AT and AN exchange predefined message, and set up the dedicated channel that is used for exchanging this message.Because before exchange transmits required parameter, set up this dedicated channel, so AT and AN use predetermined default parameter to set up Dedicated Traffic Channel, and execution parameter is consulted.Hereinafter, be the session configuration with system parameters and system variable sets definition through consulting.The processing that is used to consult this session configuration is called the session layoutprocedure.During a session, (that is to say, can between AT and AN, carry out the time period of data communication) and keep and more new session configuration.
Session layoutprocedure between AT and the AN is divided into AT and initiates (initiated) state and AN initiation state, described AT starting state is used for and will sends request for the expectation parameter to AN from AT, and described AN initiation state is used for providing the AN parameter that expectation is used to AT.AT or AN send the tabulation of the parameter value that will be used for a system parameters by ConfigurationRequest (configuring request) message.Be present in the parameter value tabulation if be used for receiving the desired value of a side of ConfigurationRequest message, then recipient's ConfigurationResponse (configuration response) message that will comprise desired value sends to the sender.
Yet, be not present in the parameter value tabulation if be used for receiving the desired value of a side of ConfigurationRequest message, then the recipient carries out the tabulation that is used for expectation parameter value that can the side of being received support sends to the sender by ConfigurationResponse message processing.Subsequently, can be with the parameter value of system parameter setting between AT and AN, supporting of association.By above processing, AT and AN carry out the parameter negotiation that is used for all agreements that will use.A side who is used for the required parameter configuration sends to the recipient with ConfigurationComplete (configuration is finished) message, and stops the session configuration process.Completed AT is disposed in session therebetween and AN discharges the Traffic Channel of setting up by predetermined default parameter, and uses new negotiation parameter.
Traditional session layoutprocedure just is recycled and reused for the processing that discharges and reconfigure Traffic Channel when having disposed new session.When using special session to dispose at AT and AN to carry out data communication, having added the parameter value that is used for the session configuration except the session configuration of current application, carry out the aforesaid processing that is used to discharge Traffic Channel equally.Yet, when the parameter of the session of in next session configuration process, also using previous configuration (promptly, the parameter constant that uses) time, the aforesaid repetitive operation that is used to discharge and reconfigures the processing of Traffic Channel causes unnecessary service delay, and has reduced customers' satisfaction level.
Traditional session layoutprocedure can not be deleted the session configuration of being stored after the negotiation of finishing between AT and the AN.For deleting default special session, AT and AN wait for another session configuration that will consult, and, must be used on the session that will delete is disposed, overriding the method that the session of new negotiation is disposed.When not when the unnecessary session of reasonable time deletion is disposed, AT and AN must unnecessarily carry out the operation that is used to continue to manage untapped session configuration.
For example, this moves to another subnet, and carry out to switch the situation of (handoff) corresponding to AT.In the case, AN must be received in the session Configuration Values that uses in the previous subnet.Because in legacy system, be not provided for deleting the process of unnecessary session configuration, so the switching target AN that is used for AT receives and is equivalent to (up to) unnecessary session configuration, and, therefore, aspect time and the memory expense is appearring.
After the negotiation of finishing between AT and the AN, traditional session layoutprocedure can not partly be upgraded the session parameter value of being stored.Thereby AT and AN must carry out the whole session configuration process that are used for upgrading special session once more, thereby cause unnecessary messages to transmit and reception and unnecessary time waste.

Embodiment
Below, will describe specific example embodiment of the present invention in detail at this by the reference accompanying drawing.In the following description, for clarity and conciseness for the purpose of, those skilled in the art is known with omitting, the function that is incorporated in this and the detailed description of configuration.
In order more preferably to understand example embodiment of the present invention, will be described in traditional session configuration process of carrying out in the High Rate Packet Data system of 1xEvolution Data Only (1xEV-DO) system for example by reference Fig. 1.That is to say that Fig. 1 illustrates the processing that is used in the consulting session configuration between (AT) 10 and access network (AN) 20 that accesses terminal of traditional High Rate Packet Data system.
In Fig. 1, step 101 to 105 in, new unicast access terminal identifier symbol (UATI) is assigned to AT 10 from AN 20, and, in step 107, use default parameter value to set up Traffic Channel.In step 109, AN 20 sends to AT 10 by Traffic Channel with ConfigurationStart (configuration beginning) message.Beginning AT initiates the session layoutprocedure of state.
Initiate in the state (AT initiated state) at AT, in step 111 and 113, AT 10 and AN 20 exchange ConfigurationRequest message and ConfigurationResponse message, and are provided for the expectation parameter value of special parameter.When fully being provided with the expectation parameter value, in step 115, AT 10 sends to AN 20 with ConfigurationComplete message, to stop the session configuration that AT initiates state.Beginning AN initiates the session layoutprocedure of state.
In AN initiation state, in step 117, AN 20 is assigned to AT 10 with the predetermined encryption key value.Subsequently, in step 119 and 121, exchange ConfigurationRequest message and ConfigurationResponse message, and be provided for the expectation parameter value of special parameter.When fully being provided with the expectation parameter value, in step 123, AN 20 will indicate the ConfigurationComplete message of having finished whole session configuration process to send to AT 10.
When consulting to be used for the parameter of session configuration, the High Rate Packet Data system uses the data structure based on the configuration attribute form.Parameter identifier and parameter value are configured configuration attribute.When execution parameter was consulted, AT and AN used related configuration attribute and parameter value are provided, and, with the result of the form storage negotiation of the configuration attribute of association.
When as shown in Figure 1 High Rate Packet Data system is using a plurality of sessions more during new session, between same parameter, also can use different parameter values based on subnet one by one based on same agreement.When moving to the subnet of another AN, to the new UATI of AT allocation map to this subnet, and execution is used for by new session layoutprocedure the more operation of new session configuration.Because when consulting session disposes, repeat request and response at the parameter that will be used for institute's protocols having, so, need the long time period.When changing subnet, the user can experience the service disruption of a very long time.
Be head it off, proposed a kind of method.In the method that is proposed, AT and AN consult when initial session disposes each other, and store the information of relevant a plurality of different sessions configuration based on subnet one by one.In the case, when in fact changing subnet, call and use in advance the session configuration information of subnet of the association of storage, so that can reduce session setup time significantly.As mentioned above, the method that is used for storing in advance the information of relevant a plurality of sessions is called many sessions layoutprocedure.
As the session layoutprocedure of Fig. 1, many sessions layoutprocedure be divided into be used for from AT for the request of the expectation parameter AT that sends to AN initiate state and be used for providing the AN of the AN parameter that expectation is used to initiate state to AT.AT or AN send the tabulation of the parameter value that will be used for a system parameters by ConfigurationRequest message.Be present in the parameter value tabulation if be used for receiving the desired value of a side of ConfigurationRequest message, then recipient's ConfigurationResponse message that will comprise desired value sends to the sender.
Yet, be not present in the parameter value tabulation if be used for receiving the desired value of recipient of ConfigurationRequest message, then the recipient is following handles: the tabulation that promptly is used for expectation parameter value that can the side of being received support sends to the sender by ConfigurationResponse message.Subsequently, can be with the parameter value of system parameter setting between AT and AN, supporting of association.
When having finished the parameter negotiation that is used for institute's protocols having in AN initiation state, AN sends to AT with predetermined SoftConfigurationComplete (soft configuration is finished) message, and notice AT: finished the negotiation of a session configuration.Individual character index (personality index) together with being used to discern related session configuration sends to AT with SoftConfigurationComplete message.AT and AN with the session configuration store finished in the value of the individual character index that is mapped to this session configuration.
After having finished a session configuration, for example, expect that predetermined session configuration continuation (the Session Configuration Continue) position of AN that starts another session configuration is set to " 1 ".When sending SoftConfigurationComplete message, the session configuration continues the position and is comprised in the SoftConfigurationComplete message.When reception session configuration continuation position was set to the SoftConfigurationComplete message of " 1 ", AT proceeded to the conversion that AT initiates state, initiates new session and disposes, and repeat above-mentioned processing.
When having finished all session configurations according to above-mentioned processing, AN sends SoftConfigurationComplete message to AT, and wherein session configuration continuation position is set to " 0 ", has finished all session configurations with indication.Among a plurality of session Configuration Values of SoftConfigurationComplete message, send predetermined session configuration token (token), the individual character index that this predetermined session configuration token indication will be used after stopping the session configuration.AT and AN discharge the Traffic Channel of setting up by default default parameter, and the parameter that will be mapped to session configuration token is applied to each agreement.
When as mentioned above, in traditional High Rate Packet Data system negotiates during one or more session, Traffic Channel that must release is set up by default parameter after having finished the session configuration.Thereby, the problem that exists the session configuration to be delayed.
Opposite with traditional method, example embodiment of the present invention provides the method that can add the new session configuration under the situation that does not discharge Traffic Channel.According to example implementation mode of the present invention, after determining to have finished all session configurations, when not changing the session configuration of using, AT and AN finish the session configuring negotiation under the situation that does not discharge Traffic Channel.
At first, with the specific example primary condition of describing according to example embodiment of the present invention that is used for AT and AN.
In can using the High Rate Packet Data system of example implementation mode of the present invention, when having stopped the session configuration, AT receives SoftConfigurationComplete message from AN, and wherein session configuration continuation position is set to " 0 ".In the case, if the session of the individual character index of the current session configuration of using indication is with identical by the session of SessionConfigurationToken (the session configuration token) indication of SoftConfigurationComplete message and dispose not overriding another session in the current session configuration of using under the second condition under first condition, then can (that is to say in release physical channels not, Traffic Channel) stops the session configuring negotiation under the situation, this is because determine not change the current session configuration of using.If under the 3rd condition except first and second conditions, between AT and AN, disagree with the recovery of previous session, then making, can under the situation of release physical channels not, stop the session configuring negotiation about after whether having changed the determining of session configuration.
In can using the High Rate Packet Data system of example implementation of the present invention, AN has the condition identical with AT.When having finished the session configuration, AN sends SoftConfigurationComplete message to AT, and wherein session configuration continuation position is set to " 0 ".In the case, if the session of the individual character index of the current session configuration of using indication then can stop the session configuring negotiation with identical by the indicated session of the SessionConfigurationToken of SoftConfigurationComplete message and dispose not overriding another session in the current session configuration of using under the second condition under the situation that does not discharge Traffic Channel under first condition.If except first and second conditions in the recovery of disagreeing with previous session under the 3rd condition, between AT and AN, then, can under the situation that does not discharge Traffic Channel, stop the session configuring negotiation having made about after whether having changed the determining of session configuration.
To wherein use method by describing with reference to Fig. 2 and Fig. 3 according to exemplary aspect AT of the present invention and exemplary operations AN based on the basic example condition.
Fig. 2 is be used for the flow chart in the method for the AN of High Rate Packet Data system consulting session configuration of diagram according to example embodiment of the present invention.
In step 201, AN carries out the protocol negotiation one by one that is used for a session configuration.After the negotiation of having finished a session configuration, in step 203, AN need to determine whether additional session configuration.When the additional session negotiation of needs, for example, in step 205, AN sends SoftConfigurationComplete message to AT, and wherein the session configuration continues the position and is set to " 1 ".Subsequently, in step 207, the session configuration store that AN will formerly consult just is in the individual character index of describing in SoftConfigurationComplete message.Subsequently, AN advances to step 201, is used for the negotiation of next session configuration with execution.
Yet, if in step 203, since all sessions configuration all finish, so AN do not need to determine the session negotiation that adds, so, for example, in step 209, AN sends SoftConfigurationComplete message to AT, and wherein session configuration continuation position is set to " 0 ".Subsequently, in step 211, the session configuration store that AN will formerly consult just is in the individual character index of describing in SoftConfigurationComplete message.Subsequently, in step 213, AN uses above-mentioned condition, and determines whether to have changed the current session configuration of using.
AN considers aforesaid three conditions in step 213.If the session of the individual character index of the current session configuration of using indication with do not upgrade the individual character index of the current session configuration of using and the not recovery of the previous session of negotiation between AT and AN as yet as yet during session negotiation identical by the indicated session of the SessionConfigurationToken of SoftConfigurationComplete message, formerly is handled, then AN determines that the current session configuration of using does not change as yet, and stops the session configuration process subsequently.
Yet if do not satisfy in described three conditions any in step 213, AN determines to have changed the current session configuration of using.Subsequently, in step 215, AN is released in the Traffic Channel of setting up in the current session configuration of using, and stops the connection to AT.In step 217, AN uses the new session configuration that changes, and, is mapped to the session configuration of the SessionConfigurationToken that describes in SoftConfigurationComplete message that is.
Fig. 3 is be used for the flow chart in the method for the AT of High Rate Packet Data system consulting session configuration of diagram according to example embodiment of the present invention.
In step 301, AT carries out the protocol negotiation one by one that is used for a session configuration.The session configuring negotiation of AT execution in step 301 is till receiving SoftConfigurationComplete message in step 303.When in step 303, receiving SoftConfigurationComplete message, in step 305, AT determines that the session configuration of SoftConfigurationComplete message continues the position and whether is set to " 0 ", and determines whether to have finished all session configurations.
If continuing the position, the session configuration is set to " 1 ", that is, do not finish all session configurations as yet, so, as the result who determines, the session configuration store that AT will formerly consult just is in the individual character index of describing in SoftConfigurationComplete message.Subsequently, AT advances to step 301, is used for the negotiation of next session configuration with execution.Yet, when receiving session configuration, AT in step 303 continues the position when being set to the SoftConfigurationComplete message of " 0 ", then in step 309, the session configuration store that AT will formerly consult just is in the individual character index of describing in SoftConfigurationComplete message.Subsequently, in step 311, AN determines whether to have changed the current session configuration of using.
In step 311, AT considers aforesaid three conditions.If the session of the individual character index of the current session configuration of using indication with do not upgrade the individual character index of the current session configuration of using and the not recovery of the previous session of negotiation between AT and AN as yet as yet during session negotiation identical by the indicated session of the SessionConfigurationToken of SoftConfigurationComplete message, formerly is handled, then AT determines that the current session configuration of using does not change as yet, and stops the session configuration process subsequently.
Yet if do not satisfy in described three conditions any in step 311, AT determines to have changed the current session configuration of using.Subsequently, in step 313, AT is released in the Traffic Channel of setting up in the current session configuration of using, and stops the connection to AN.In step 315, AT uses the new session configuration that changes, and, is mapped to the session configuration of the SessionConfigurationToken that describes in SoftConfigurationComplete message that is.
With the session collocation method of describing according to another example embodiment of the present invention.
In this example embodiment, AT does not determine whether the current session configuration of using changes, and still, AN has indicated whether to use the information of session configuration.In this exemplary method, AN can indicate: whether use specific session configuration after having finished the session configuring negotiation.When specific session configuration is used in the AN indication, the AT release physical channels, and use the specified session configuration of AN.Yet when AN does not indicate when using specific session configuration, AT finishes the session configuring negotiation under the situation of release physical channels not.
For example, now, with the AT that describes based on 1xEV-DO.Continue the position when being set to the SoftConfigurationComplete message of " 0 " when having finished the session configuring negotiation and having received session configuration, AT reads the predetermined session of submission (Commit) field and submits (Session Commit) position to, described session is submitted to the position to continue the position together with the session configuration and is sent, and determines whether to use specific session.When session submits to position (commit bit) when being set to " 1 ", AT uses the session configuration with the corresponding individual character index of SessionConfigurationToken, described SessionConfigurationToken sends together with SoftConfigurationComplete message.In managing herein, but release physical channels.Yet when receiving session when submitting to the position to be set to the SoftConfigurationComplete message of " 0 ", AT continues to keep the current session configuration of using under the situation of release physical channels not.
For example, now, with the AN that describes based on 1xEV-DO.When having finished the session configuring negotiation, send the session configuration and continue the SoftConfigurationComplete message that the position is set to " 0 ".When after being desirably in the session configuring negotiation, using the session configuration that is mapped to specific individual character index, the session of SoftConfigurationComplete message submits to the position to be set to " 1 ", and together with sending SoftConfigurationComplete message with the corresponding SessionConfigurationToken of individual character index that will use.Subsequently, the session configuration of the corresponding individual character index of SessionConfigurationToken of using and being sent.In managing herein, but release physical channels.Yet when continuing to use current session configuration after being desirably in the session configuring negotiation, AN sends session and submits to the position to be set to the SoftConfigurationComplete message of " 0 ", and continues to keep the current session configuration of using.
Table 1 shows the field that is used for indicating whether to use at AN the SoftConfigurationComplete message of specific session configuration that is proposed.
Table 1
| Field | Length (position) |
| MessageID | 8 |
| TransactionID | 8 |
| PersonalityIndexStore | 4 |
| Field | Length (position) |
| Continue (Continue) | 1 |
| Submit to (Commit) | 0 or 1 |
| SessionConfigurationToken | 0 or 16 |
| Keep (Reserved) | 0-7 (as required) |
In table 1, the MessageID field is used for distinguishing between different message, and is set to be used to indicate the message identifier of SoftConfigurationComplete message.The TransactionID field is to be used for the identifier distinguished between different SoftConfigurationComplete message.When having disposed new SoftConfigurationComplete message, just in the TransactionID field, specify concurrent sending by being incremented 1 value divided by 256 (2
8) (dividing a value incremented byone by 256) and the remainder that obtains.The individual character index of the session configuration of consulting has wherein been stored in the indication of PersonalityIndexStore field.
When the SoftConfigurationComplete message that is received was first SoftConfigurationComplete message after the initiation session configuring negotiation, AT stored in indicated individual character index: from moment of initiation session configuring negotiation till receiving SoftConfigurationComplete message during in the session Configuration Values consulted.When the SoftConfigurationComplete message that is received was not first SoftConfigurationComplete message, AT stored in indicated individual character index: from moment of receiving previous SoftConfigurationComplete message till receiving current SoftConfigurationComplete message during in the session Configuration Values consulted.
When the SoftConfigurationComplete message that is sent was first SoftConfigurationComplete message after the initiation session configuring negotiation, AN stored in indicated individual character index: from moment of initiation session configuring negotiation till sending SoftConfigurationComplete message during in the session Configuration Values of negotiation.When the SoftConfigurationComplete message that is sent was not first SoftConfigurationComplete message, AN stored in indicated individual character index: from moment of sending previous SoftConfigurationComplete message till sending current SoftConfigurationComplete message during in the session Configuration Values of negotiation.
In table 1, continue the session configuration that field indicates whether to continue to be mapped to new individual character index.When the continuation field has value " 1 ", continue to be mapped to the session configuration of new individual character index.When the continuation field has value " 0 ", stop the session configuration.In table 1, submit to field to indicate whether to submit to specific session configuration.Only when the continuation field had value " 0 ", this submitted to field just to be included in this message.
When submitting to field to have value " 1 ", AT and AN use the session configuration that is mapped to by the individual character index of SessionConfigurationToken field indication in the table 1.In the case, AT and AN release physical channels.The individual character index that the indication of SessionConfigurationToken field will be used, and only when submitting to field to have value " 1 ", just be included in this message.AT and AN use and are mapped to the session configuration with such individual character index, and this individual character index has the identical value of value with 4 high significance bits of SessionConfigurationToken field.In this example embodiment, preferably, the SessionConfigurationToken field is set to 16.The individual character index is set to 4, but the figure place of individual character index is variable.
Next, will be by with reference to Fig. 4 and Fig. 5 and describe session collocation method in more detail according to another example embodiment of the present invention.
Fig. 4 is the method flow diagram of diagram according to the session configuration process of carrying out of another example embodiment of the present invention in the AN of High Rate Packet Data system.Particularly, Fig. 4 illustrates the operation of the AN in the session layoutprocedure, wherein, and release physical channels unnecessarily not.
In step 401, AN carries out the protocol negotiation one by one that is used for a session configuration.After the negotiation of having finished a session configuration, in step 403, AN need to determine whether additional session configuration.Additional if desired session configuration, then in step 405, AN sends SoftConfigurationComplete message, wherein continues the position and is set to " 1 ".Here, when having disposed session, just SoftConfigurationComplete message is sent to AT.The session configuration store that the AN of transmission SoftConfigurationComplete message will formerly consult just is in the individual character index of describing in SoftConfigurationComplete message.Subsequently, AN advances to step 401, to carry out next session configuring negotiation.
If the definite result who has finished in all session configurations and the step 403 is that the session that does not need to add is disposed, then AN determines whether to use again special session.If use special session again, then in step 411, AN sends SoftConfigurationComplete message to AT, wherein continues the position and is set to " 0 " and submits to field to be set to " 1 ".Subsequently, in step 413, the session configuration store that AN will formerly consult just is in the individual character index of describing in SoftConfigurationComplete message.Subsequently, in step 415, AN is released in the physical channel of setting up in the current session configuration of using.Subsequently, in step 417, AN uses the new session configuration that changes, and, is mapped to the session configuration of the SessionConfigurationToken that describes in SoftConfigurationComplete message that is, and end session configuration process subsequently.
Yet if the definite result in the step 409 does not need to use new session, so, in step 419, AN sends SoftConfigurationComplete message to AT, wherein continues the position and submits to field to be set to " 0 " respectively.Subsequently, in step 421, the session configuration store that AN will just formerly consult in the individual character index of in SoftConfigurationComplete message, describing, and, subsequently, end session configuration process under the situation of release physical channels not.According to above-mentioned example embodiment, AN can send information to AT, indicates whether to use after having finished the session configuring negotiation specific session configuration, and can keep existing physical channel when not changing previous session configuration.
Fig. 5 is among the ATs of High Rate Packet Data system the flow chart of session configuration process of diagram according to another example embodiment of the present invention.Particularly, Fig. 5 illustrates the operation of the AT in the session layoutprocedure, wherein, and release physical channels unnecessarily not.
In step 501, AT carries out the protocol negotiation one by one that is used for a session configuration.After the negotiation of having finished a session configuration, in step 503, AT receives SoftConfigurationComplete message.When receiving SoftConfigurationComplete message in step 503, in step 505, AT determines whether the continuation position of SoftConfigurationComplete message is set to " 0 ".When the continuation position was set to " 1 ", in step 507, the session configuration store that AT will formerly consult just was in the individual character index of describing in SoftConfigurationComplete message.Subsequently, AT advances to step 501, is used for the negotiations process of new session configuration with execution.
When in step 505, receive and continue the position when being set to the SoftConfigurationComplete message of " 0 ", AT determines to have finished all sessions configurations.Subsequently, in step 509, the session configuration store that AT will formerly consult just is in the individual character index of describing in SoftConfigurationComplete message.Subsequently, in step 511, AT checks the value of submitting the position to, and determines whether to use new session configuration.If in step 511, to submit place value to be " 1 ", then in step 513, AT is released in the physical channel that the current session of using is set up in disposing, and stops the connection to AN.In step 515, AT uses the new session configuration that changes, and, is mapped to the session configuration of the SessionConfigurationToken that describes in SoftConfigurationComplete message that is.
If in step 511, to submit place value to be " 0 ", AT end session configuration process immediately under the situation that is not released in the physical channel that the current session of using sets up in disposing then.According to the foregoing description, AT can based on receive from AN information and use specific session configuration, this information to indicate whether to use specific session configuration, and can when not changing previous session configuration, keep existing physical channel.
Next, with the method for describing according to example embodiment of the present invention of the session of between AT and AN, consulting configuration that is used to delete pre-stored.
In the method that in example embodiment of the present invention, proposes, AN need not to begin the session configuration process, and send the deletion conversation message, and removing the session configuration of pre-stored, described deletion conversation message comprises individual character ID or the index and affairs (transaction) ID of the session that will delete.When receiving the deletion conversation message, AT deletes the session information that is mapped to indicated individual character index from memory.In example implementation, during the session configuring negotiation, do not transmit and receive the deletion conversation message.
Table 2 shows the example according to deletion conversation message of the present invention, and this deletion conversation message is used to remove the session configuration of pre-stored.
Table 2
| Field | Length (position) |
| MessageID | 8 |
| TransactionID | 8 |
| PersonalityCount | 4 |
PersonalityCount+1 example of following record
| PersonalityIndex | 0 or 4 |
| Keep (Reserved) | 0 or 4 |
In table 2, the indication of MessageID field is used to discern the value of the message identifier of deleting conversation message.The TransactionID field is used to distinguish owing to network condition causes the order that is repeated the deletion conversation message that transmits or be delayed.When transmitting the deletion conversation message, for example, AN increases progressively 1 with the value of TransactionID field.
In table 2, the number (for example, the number of individual character index-1) of the individual character index that will delete in the PersonalityCount field indication deletion conversation message.PersonalityIndex field indication map is to the individual character index of the session configuration that will delete.When receiving the deletion conversation message from AN, the AT deletion is mapped at least one session configuration of the individual character index that comprises in this message.
When receiving the deletion conversation message, the indicated session of AT deletion is disposed, and response message is sent to AN.AN can pass through to receive response message, and determines whether AT has deleted this session configuration, deletes so that can stably carry out the session configuration.In the case, AN receives response message, and subsequently, when definite AT has deleted this session configuration, deletes the session configuration of himself.
Next, be used for upgrading the method that the session of consulting of (correction) pre-stored is disposed with describing according to example embodiment of the present invention between AT and AN.
In the prior art, the method for the special session configuration among the session configuration of a plurality of storages is handled and upgraded to undefined being used for carrying out session negotiation between AT and the AN.Even when some parameter value that comprises is proofreaied and correct in AT and AN expectation in the special session configuration, also must intactly carry out session negotiation and handle.For example, when AT and AN have stored session configuration 1,2 and 3 and when expecting the special parameter A of more new session configuration 2, in the prior art, must dispose all parameters of 2 to session and re-execute session negotiation and handle.
Example implementation of the present invention provides and can carry out under the situation that traditional AT and the session negotiation between the AN handle imperfectly, upgrade the method for the special parameter of special session configuration.In exemplary method proposed by the invention, the AN (or AT) of the renewal of request special parameter generates or activates the agreement of using the parameter that will proofread and correct in the session configuration of association, to proofread and correct the session Configuration Values of being stored.Subsequently, target AT (or AN) sends the InConfiguration example that will be described below and activates message, and generates or activate the agreement of the relevant parameter that uses the correlating sessions configuration.
Subsequently, AN of the renewal of required parameter (or AT) and the AT (or AN) that receives this request use and knownly to be used for the message of parameter negotiation and to upgrade the parameter value of related agreement, the protocol definition that the described known message that is used for parameter negotiation generates or activates by institute.For example, known message is AttributeUpdateRequest message, AttributeUpdateAccept message, AttributeUpdateReject message, ConfigurationRequest message and ConfigurationResponse message.In each agreement, define these and be used for the message of parameter negotiation.After having finished the renewal processing, other parameter that AN (or AT) that request is upgraded and target AT (or AN) dispose the updated parameters and the related session of the agreement of association is stored in the individual character index, and finishes the session config update.
In can using the High Rate Packet Data system of example embodiment of the present invention, AN (or AT) generates or activates the protocol of I nConfiguration example of the relevant parameter that uses session information, the parameter (or configuration attribute) that disposes with the special session that upgrades the pre-stored by the session configuring negotiation.In example embodiment, protocol of I nConfiguration example is an independently performance element, by parameter value and the protocol operation configuration that defines in agreement.The InConfiguration example that generates or activate is used for consulting the parameter used in the agreement of association, and only definition is used for the minimum operation of parameter negotiation.
When AN begins the renewal of parameter (or configuration attribute) of special session configuration, its InConfiguration example that will define in example implementation of the present invention activates message and sends to AT, so that generate and activate the protocol of I nConfiguration example that uses related parameter.When successfully having sent InConfiguration example activation message, the message that AN and AT operation parameter are consulted is held consultation, and with correction parameter values, the message of described parameter negotiation is defined relatively by the InConfiguration example with associated protocol.After having consulted parameter value fully, AN disposes the session of association that updated parameters value and other parameter are stored in the individual character index of this session configuration.
Receive InConfiguration example activation message from AN after, AT generates or activates the InConfiguration example of specific protocol, and this specific protocol is associated with the individual character index of describing in InConfiguration example activation message.Subsequently, AT is used for the message of the parameter negotiation that defines in associated protocol, and consults the parameter value that will proofread and correct.After fully having consulted parameter value, AT disposes the session of association that updated parameters value and other parameter are stored in the individual character index of this session configuration.
In can using the High Rate Packet Data system of example implementation of the present invention, when AT begins the renewal of parameter (or configuration attribute) of special session configuration, the InConfiguration example of its generation or activated protocol, parameter (or configuration attribute) with the special session configuration of upgrading pre-stored, this agreement is used the relevant parameter of correlating sessions configuration.AT is sent in the InConfiguration example that defines in the example implementation of the present invention to AN and activates message, so that generate the also InConfiguration example of activated protocol, in this agreement, has used the parameter of the association of related session configuration in AT.When successfully having sent the InConfiguration example and activate message, AT holds consultation with the message of AN operation parameter negotiation, comes correction parameter values, and the message definition of described parameter negotiation is with relevant with the InConfiguration example of associated protocol.After the negotiation of having finished parameter value, AT is stored in updated parameters value and other parameter of the session configuration of association in the individual character index of this session configuration.
Receive InConfiguration example activation message from AT after, AN generates or activates the InConfiguration example of specific protocol, and described specific protocol is associated with the individual character index of describing in InConfiguration example activation message.Subsequently, AN is used for the message of the parameter negotiation that the agreement in association defines, and consults the parameter value that will proofread and correct.After the negotiation of having finished parameter value, AN disposes the session of association that updated parameters value and other parameter are stored in the individual character index of this session configuration.
Next, will be by in detail describing session updates method according to example embodiment of the present invention with reference to Fig. 6 and Fig. 7.
Fig. 6 is the flow chart of the side's that diagram is used for according to an embodiment of the invention when more new session disposes in the High Rate Packet Data system, transmission InConfiguration example activates message operation.
At first, in step 601, when AT (or AN) upgrades the parameter of special session configuration of pre-stored in expectation, generate or activate the protocol of I nConfiguration example of the parameter of the association of using the special session configuration that to proofread and correct.In step 603, the InConfiguration example that the AT that begins to upgrade (or AN) will define in the present invention activates message and sends to target AN (or AT), InConfiguration example with generation or activated protocol, in this agreement, in target AN (or AT), used the parameter of the association of special session configuration.
When successfully having sent InConfiguration example activation message, in step 605, AT (or AN) and target AN (or AT) hold consultation at being used for the parameter value that the message of the parameter negotiation that defines relatively with related protocol of I nConfiguration example proofreaies and correct by use.If finished the negotiation of parameter value in step 607, then in step 609, AT (or AN) is stored in updated parameters value and other parameter of the session configuration of association in the individual character index of this session configuration.
Fig. 7 for diagram according to example embodiment of the present invention be used for when the High Rate Packet Data system more new session when configuration, receive a side's of InConfiguration example activation message the flow chart of operation.
When the AT (or AN) from the renewal of the special parameter of queued session configuration receives the InConfiguration example when activating message, in step 701, target AN (or AT) generates or activates the InConfiguration example of the renewal target protocol of the special session configuration that is associated with individual character index that comprises and protocol type in the InConfiguration example activation message that is received.
In step 703, at the parameter value that will proofread and correct, target AN (or AT) is used for the message of the parameter negotiation that the agreement in association defines, and holds consultation with AT (or AN) that request is upgraded.In step 705, finished after the negotiation of parameter value, in step 707, target AN (or AT) is stored in updated parameters value and other parameter of the session of association configuration in the individual character index of this session configuration.
Next, with the method for describing according to another example embodiment of the present invention, this method is used for the session configuration of renewal (correction) pre-stored by the negotiation between AT and the AN.
In another example embodiment of the present invention, the request (hereinafter, being called PersonalityUpdateRequest (individual character update request) message) that AT (or AN) will be used to upgrade specific configuration attribute sends to target AN (or AT).In example implementation, configuration attribute is specified the protocol type of the indicated special session configuration of individual character index.
When target AN (or AT) determines whether to use related configuration attribute value, and expectation when using the configuration attribute value of being asked, its AT (or AN) that upgrades to request sends expression and accepts the response of update request (hereinafter, being called PersonalityUpdateAccept (individual character is upgraded and accepted) message).Yet if use the configuration attribute of being asked, the response (hereinafter, being called PersonalityUpdateReject (individual character is upgraded refusal) message) that will represent to refuse update request sends to the AT (or AN) of request renewal.Thereby AT or AN can pass through to repeat aforesaid operations, and upgrade the configuration attribute value of pre-stored.
Table 3 shows being suggested among the present invention and is used for the example of field of PersonalityUpdateRequest message of the configuration of new session more.
Table 3
In table 3, MessageID field Indication message type, and be set to be mapped to the identifier of PersonalityUpdateRequest message.The TransactionID field is used for distinguishing a pair of PersonalityUpdateRequest message and response message thereof.When receiving (promptly to the response message of update request, PersonalityUpdateAccept/Reject message) time, AN or AT identification is included in the TransactionID in the response message, and response message is defined as response to the PersonalityUpdateRequest message with same TransactionID.
In table 3, the PersonalityIndex field is used to refer to the individual character index that is used for the configuration attribute that is associated with update request.The type of the agreement under the configuration attribute that protocol type field is used to refer to update request is associated.AN or AT that request is upgraded describe at least one configuration attribute that will upgrade in the protocol type of individual character index in the AttributeRecord of table 3 (attribute record) field, and transmit this message.
When having disposed the AttributeRecord field according to example embodiment, can limit like this, that is: AN or AT only are that a configuration attribute proposes a value.The AN or the AT that send PersonalityUpdateRequest message can be limited like this, that is: the session configuration of the current individual character index that is using of this information updating can not be used.Replacedly, in PersonalityUpdateRequest message, can not comprise and transmit at least two configuration attributes.
When receiving PersonalityUpdateRequest message, the configuration attribute value that AT (or AN) determines whether to use the other side's AN (or AT) to be provided, and send PersonalityUpdateAccept or PersonalityUpdateReject message message in response.Table 4 and table 5 show respectively with to the field structure of corresponding PersonalityUpdateAccept message of the response message of PersonalityUpdateRequest message and PersonalityUpdateReject message.
Table 4
| Field | Length (position) |
| MessageID | 8 |
| TransactionID | 8 |
Table 5
| Field | Length (position) |
