Description

Secondary activating flow path processing method and device that network side is initiated
Technical field
The present invention relates to wireless communication field, particularly the secondary activating flow path processing method and the device of network side initiation.
Background technology
(Universal Mobile Telecommunications System UMTS) is the 3-G (Generation Three mobile communication system) that adopts the WCDMA air interface technologies to universal mobile telecommunications system.The UMTS system comprise Radio Access Network (Radio Access Network, RAN) and core network (Core Network, CN).Wherein Radio Access Network is used to handle all and wireless access function associated, and core network handles that all voice calls are connected with data in the UMTS system, and the exchange of realization and external network and routing function.
(Radio Network Controller RNC) forms with base station node B RAN by radio network controller.Interface between RNC and the CN is the Iu interface, and NodeB is connected by Iub interface with RNC.Interconnected by Iur between the RNC, Iur can connect or connect by transmission network by the direct physical between the RNC.RNC is used for distributing and is attached thereto with control or the Radio Resource of relevant NodeB.NodeB then finishes the conversion of the data flow between Iub interface and the Uu interface, also participates in a part of RRM simultaneously.RNC is used to control the Radio Resource of RAN, mainly finishes functions such as connection foundation and disconnection, switching, the merging of grand diversity, RRM control.
In the UMTS system, core network comprise Serving GPRS Support Node (Serving GPRSSupport Node, SGSN) and Gateway GPRS Support Node (Gateway GPRS Support Node, GGSN) two entities.
SGSN is as a basic composition network element, and its significant feature is exactly to be the subscriber equipment of this SGSN coverage (User Equipment, UE) the IP grouping of forwarding I/O.The function that SGSN provides comprises: the route and the forwarding capability of the packet data package in this SGSN area, for all packet domain users in this SGSN area service, encryption and authentication functions, conversation management functional, mobile management function are provided, with UMTS Radio Access Network (UMTS Territorial Radio Access Network, UTRAN), GGSN, attaching position register (Home Location Register, interface function such as HLR).
GGSN is as a basic Network Element Function entity, provides packet with route between the external data network and encapsulation.Which GGSN the user selects as gateway, be in pdp context activation according to the Access Point Name of user's CAMEL-Subscription-Information and user's request (Access Point Name, APN) definite.The function that GGSN provides comprises: with the critical point function of extenal grouped network, conversation management functional etc.
The secondary activating PDP Context is based on existing PDP Context, therefore there are not IP address negotiation, APN selection etc., secondary activating is exactly on the basis of existing carrying (corresponding to existing PDP Context), increases the carrying (corresponding to the PDP Context that secondary activating produced) with different QoS value.The PDP Context that carries out secondary activating and produce has identical pdp address and APN with the corresponding PDP Context of former carrying.
As shown in Figure 1, the secondary activating PDP Context flow process of existing network side initiation comprises:
Step 101: initiate PDP context activation.When the GGSN decision is set up new carrying on the basis of existing carrying, inform SGSN, carried in this message and set up the necessary parameter of new bearer (as: QoS) by initiating PDP context activation message.
Step 102: request secondary activating PDP Context.After SGSN receives the initiation PDP context activation message that GGSN sends, send request secondary activating PDP Context message, also carried in this message and set up the necessary parameter of new bearer (as: QoS) to subscriber equipment.Qos parameter in this message is consistent with the QoS in initiating PDP context activation message.
Step 103: secondary activating PDP Context process.After subscriber equipment is received and set up the necessary parameter of new bearer, send the request of secondary activating PDP Context.Carry demand in this request to QoS.After SGSN receives this request, can come the QoS of restricting user equipment request according at least one item in the ability of SGSN self, SGSN present load, user signing contract information, operator pre-configured;
Step 104: create the PDP Context request.Carry demand in this request to QoS, this demand may with the request of secondary activating PDP Context in consistent, also may be through the QoS demand after the SGSN restriction.After GGSN receives this request, can limit or increase the QoS of SGSN request;
Step 105: create the PDP Context response.Carry requirement in this response to QoS, this requirement may be in the step 102 GGSN restriction or increase after qos requirement.After SGSN receives this response, can limit QoS with reference to the method described in the step 103.
Step 106:SGSN sets up RAN side resource according to the QoS in the step 105.In this step, the actual pairing QoS of RAN side resource that sets up is lower than the initial QoS that wishes foundation of step 105 possibly.
Step 107: upgrade the PDP Context request.After having set up RAN side resource, SGSN informs GGSN by this message with the pairing QoS of RAN side resource that sets up, and allows GGSN accept this QoS and no longer hold consultation by " do not consult QoS indication " parameter.
Step 108: upgrade the PDP Context response.This message is the response after GGSN receives renewal PDP Context request message.QoS information may be comprised in this message, also this information may be do not comprised.
Step 109: the secondary activating PDP Context is accepted.SGSN finishes with the whole secondary activating PDP Context of this message informing subscriber equipment flow process.In this message, SGSN informs subscriber equipment with the QoS that consults to finish, if subscriber equipment can't be accepted this QoS, holds consultation together with application layer, if still can't accept then to initiate the deexcitation flow process.
In the secondary activating process that network side is initiated, may there be difference in the QoS (as: the secondary activating PDP Context is accepted the entrained QoS of message) that QoS that GGSN asked (as: initiate PDP context activation message entrained QoS) and subscriber equipment are received, this be because of:
1, after SGSN received the request of secondary activating PDP Context, SGSN may limit QoS.
2, after GGSN received to create the PDP Context request, GGSN may limit or promote QoS.
3, after SGSN received to create the PDP Context response, SGSN may limit QoS.
4, when setting up RAN side resource, might be limited by QoS.
When the QoS that QoS and subscriber equipment received that GGSN asked was inequality, the QoS that newly-built carrying just might occur can't satisfy the situation of actual requirement.According to existing process, the originating end of this process is GGSN, and initial QoS also comes from GGSN, and subscriber equipment does not also know whether last received QoS can meet the demands.In the secondary activating that network side is initiated, when the QoS of newly-built carrying can't satisfy under the situation of actual requirement the rational processing procedure of neither one in the prior art owing to be restricted during the course.
Summary of the invention

Embodiment
As shown in Figure 2, the secondary activating flow path processing method that one embodiment of the present of invention provide a kind of network side to initiate, this method comprises:
Step 201: obtain the condition whether judgement QoS meets the demands;
Step 202: in the secondary activating flow process, whether meet the demands according to described condition criterion QoS;
Step 203:, carry out respective handling according to the result of described judgement.
In the foregoing description, by in the secondary activating flow process that network side is initiated, introducing the condition of judging whether QoS meets the demands, and have increased access to the step of the condition of judging whether QoS meets the demands, make follow-up can whether meeting the demands according to condition criterion QoS.In the secondary activating flow process that network side is initiated, check in time whether the QoS after consulting can satisfy business need, thereby in the secondary activating flow process that network side is initiated, realize guarantee like this QoS.
Need to prove that the condition that whether said judgement QoS meets the demands among the foregoing description and following all embodiment includes but not limited to the requirement of QoS lower limit, or the requirement of QoS excursion, or does not consult indication, or the QoS tabulation.
The requirement of QoS lower limit is meant and satisfies the actual needed minimum QoS that requires.For example: if with the QoS of 0～5 integer representation different stage, 0 is minimum, and 5 for the highest.In the secondary activating PDP Context process that network side is initiated, it is 5 that network side can require the QoS rank, is 3 but require the decision condition of QoS lower limit.Promptly when QoS in secondary activating PDP Context process by when degradation, it is minimum can not to be lower than 3.If follow-up judgement QoS is lower than 3, then will be regarded as to satisfy actual requirement.
The requirement of QoS excursion is meant to satisfying the maximum mobility scale of QoS that actual requirement can allow.For example: network side can require QoS to be not less than 50% of initial requirement.When QoS is demoted, and be lower than at 50% o'clock of initial requirement in secondary activating PDP Context process, will be regarded as to satisfy actual requirement.
Do not consult indication and can regard a kind of decision condition as yet.Do not consult to indicate requirement that the initial QoS that requires of network side is not done change,, just will be regarded as to satisfy actual requirement in case QoS is demoted in secondary activating PDP Context process.
The QoS tabulation also is a kind of decision condition.Comprise at least one QoS in the QoS tabulation.QoS in this tabulation represents the QoS that can choose in the secondary activating PDP Context process.The QoS in this tabulation scope is not the QoS that discontented full border requires.Therefore, just can judge according to this tabulation whether the QoS in the secondary activating PDP Context process that network side initiates meets the demands.
Below introduce other embodiment of the present invention.In following examples, may refer to some content among Fig. 1.Of particular note, only be in order to be illustrated more clearly in embodiments of the invention to quoting of these contents, and can not prove that the other guide except that the content that is cited belongs to prior art.
The secondary activating flow path processing method that another embodiment of the present invention provides a kind of network side to initiate obtain the condition whether judgement QoS meets the demands in this method, and the entity that whether meets the demands according to described condition criterion QoS is a subscriber equipment.
In the present embodiment, subscriber equipment obtains to judge that the condition whether QoS meets the demands has two kinds of approach.A kind of is to obtain decision condition from the message of network side transmitted, and another kind is by pre-configured acquisition decision condition.
If from the message of network side transmitted, obtain decision condition, because when network side is initiated the secondary activating PDP Context, it is that GGSN provides that initial Q oS requires, so the condition whether this judgement QoS meets the demands is carried at and information can be delivered to the message of subscriber equipment from GGSN.Specifically, GGSN can be carried at this condition and initiate in the PDP context activation message, after SGSN receives this message, this condition is carried in the request secondary activating PDP Context message sends to subscriber equipment.Ask secondary activating PDP Context message to be considered to information to be delivered to from GGSN the message of subscriber equipment this moment.GGSN also can send a specific messages and come notifying user equipment to judge the condition whether QoS meets the demands, and this condition is not carried in other existing message.
GGSN will judge that the condition whether QoS meets the demands sends to after the subscriber equipment, can preserve, or the part preservation, or do not preserve described condition.
Subscriber equipment also can be by pre-configured acquisition decision condition.For example, can set QoS and be not less than 30% of initial requirement, or set and do not consult QoS.Certainly, also can be at the pre-configured different decision condition of different types of service.
After the condition whether subscriber equipment acquisition judgement QoS meets the demands, just can judge in the flow process of secondary activating PDP Context whether the pairing QoS of newly-built carrying meets the demands.Can have multiple choices the opportunity of judging, below explanation respectively.
First kind: shown in Fig. 1 step 106, initiate to need to set up RAN side resource in the secondary activating PDP Context process at network side.If this moment, subscriber equipment obtained the condition of judging whether QoS meets the demands, then can whether meet the demands at the QoS that RAN side resource is set up RAN side resource that in the process judgement will be set up and provided.When judgement can meet the demands, continue secondary activating PDP Context flow process; When judging that QoS that RAN side resource provides does not meet the demands, stop the secondary activating flow process, and the processing of failing.It can be to remove the RAN side resource that has taken that described failure is handled, and sends a notification message to SGSN and GGSN, and informs failure cause; Also can be to initiate the deexcitation flow process.
Second kind: shown in Fig. 1 step 109, SGSN can send the secondary activating PDP Context to subscriber equipment and accept message in network side initiation secondary activating PDP Context process, carries the pairing QoS information of newly-built carrying in this message.If this moment, subscriber equipment obtained to judge the condition whether QoS meets the demands, can judge after receiving this message then whether the pairing QoS of newly-built carrying meets the demands.When judgement can meet the demands, this secondary activating PDP Context flow process was finished; When judging that the pairing QoS of newly-built carrying does not meet the demands, the subscriber equipment processing of failing.It can be to initiate the deexcitation flow process that described failure is handled, with this deleting load-bearing that can not meet the demands; Also can be to send a notification message, and inform failure cause to SGSN and GGSN.
Need to prove, more than only be in order to be illustrated more clearly in present embodiment to quoting of Fig. 1, and can not prove that the other guide except that the content that is cited belongs to prior art.
The secondary activating flow path processing method that another embodiment of the present invention provides a kind of network side to initiate obtain the condition whether judgement QoS meets the demands in this method, and the entity that whether meets the demands according to described condition criterion QoS is SGSN.
In the present embodiment, SGSN obtains to judge that the condition whether QoS meets the demands has two kinds of approach.A kind of is from information can being obtained decision condition from GGSN is delivered to the message of SGSN, and another kind is by pre-configured acquisition decision condition.
If from the message that GGSN sends, obtain decision condition, because when network side is initiated the secondary activating PDP Context, it is that GGSN provides that initial Q oS requires, so the condition whether this judgement QoS meets the demands is carried at and information can be delivered to the message of SGSN from GGSN.Specifically, GGSN can be carried at this condition and initiate to send to SGSN in the PDP context activation message; GGSN also can be carried at this condition to create in the PDP Context response message and send to SGSN; GGSN can also be carried at this condition to upgrade in the PDP Context response message and send to SGSN.GGSN can also notify SGSN to judge the condition whether QoS meets the demands by sending a specific messages, and this condition is not carried in other existing message.
In addition, in initiating PDP context activation message and request secondary activating PDP Context message, GGSN can will judge that the condition whether QoS meets the demands sends to subscriber equipment.Subscriber equipment can be transmitted to SGSN with this condition in secondary activating PDP Context request message.In this case, secondary activating PDP Context request message can be considered to information can be delivered to from GGSN the message of SGSN.
GGSN will judge that the condition whether QoS meets the demands sends to after the SGSN, can preserve, or the part preservation, or do not preserve described condition.
SGSN also can be by pre-configured acquisition decision condition.For example, can set QoS and be not less than 30% of initial requirement, or set and do not consult QoS.Certainly, also can be at the pre-configured different decision condition of different types of service.
After the condition whether SGSN acquisition judgement QoS meets the demands, just can judge in the flow process of secondary activating PDP Context whether the pairing QoS of newly-built carrying meets the demands.Can have multiple choices the opportunity of judging, below explanation respectively.
First kind: in secondary activating PDP Context flow process, SGSN changes QoS sometimes.For example, SGSN may limit QoS after receiving the request of secondary activating PDP Context; SGSN also may limit QoS after receiving that creating PDP Context responds.At this moment, if SGSN has obtained to judge the condition whether QoS meets the demands, then can whether meet the demands according to the QoS after this condition criterion change.When judgement can meet the demands, continue secondary activating PDP Context flow process; When the QoS after judging change does not meet the demands, stop the secondary activating flow process, and the processing of failing.It can be to send a notification message to subscriber equipment and GGSN that described failure is handled, and informs failure cause; Also can be to initiate the deexcitation flow process.
The basis of above-mentioned SGSN change QoS can be in the ability of described SGSN, described SGSN present load, user signing contract information, operator pre-configured at least one.
Second kind: shown in Fig. 1 step 103, subscriber equipment can send secondary activating PDP Context request message to SGSN in network side initiation secondary activating PDP Context process, carries the pairing QoS information of newly-built carrying in this message.If SGSN this moment has obtained to judge the condition whether QoS meets the demands, can judge after receiving this message then whether the QoS information that this message is carried meets the demands.When judgement can meet the demands, continue secondary activating PDP Context flow process; When judging that QoS information that this message is carried does not meet the demands, stop the secondary activating flow process, and the processing of failing.It can be to send a notification message to subscriber equipment and GGSN that described failure is handled, and informs failure cause; Also can be to initiate the deexcitation flow process.
The third: shown in Fig. 1 step 105, GGSN can send to SGSN and create the PDP Context response message in network side initiation secondary activating PDP Context process, carry the pairing QoS information of newly-built carrying in this message.If SGSN this moment has obtained to judge the condition whether QoS meets the demands, can judge after receiving this message then whether the QoS information that this message is carried meets the demands.When judgement can meet the demands, continue secondary activating PDP Context flow process; When judging that QoS information that this message is carried does not meet the demands, stop the secondary activating flow process, and the processing of failing.It can be to send a notification message to subscriber equipment and GGSN that described failure is handled, and informs failure cause; Also can be to initiate the deexcitation flow process.
The 4th kind: shown in Fig. 1 step 106, initiate to need to set up RAN side resource in the secondary activating PDP Context process at network side.If SGSN this moment has obtained the condition of judging whether QoS meets the demands, then can whether meet the demands at the QoS that RAN side resource is set up RAN side resource that in the process judgement will be set up and provided.When judgement can meet the demands, continue secondary activating PDP Context flow process; When judging that QoS that RAN side resource provides does not meet the demands, stop the secondary activating flow process, and the processing of failing.It can be to remove the RAN side resource that has taken that described failure is handled, and sends a notification message to subscriber equipment and GGSN, and informs failure cause; Also can be to initiate the deexcitation flow process.
The 5th kind: shown in Fig. 1 step 108, GGSN can send to SGSN and upgrade the PDP Context response message in network side initiation secondary activating PDP Context process, may carry the pairing QoS information of newly-built carrying in this message.If carry QoS information in this message, and this moment, SGSN obtained to judge the condition whether QoS meets the demands, and can judge after receiving this message then whether the QoS information that this message is carried meets the demands.When judgement can meet the demands, continue secondary activating PDP Context flow process; When judging that QoS information that this message is carried does not meet the demands, stop the secondary activating flow process, and the processing of failing.It can be to send a notification message to subscriber equipment and GGSN that described failure is handled, and informs failure cause; Also can be to initiate the deexcitation flow process.
Need to prove, more than only be in order to be illustrated more clearly in present embodiment to quoting of Figure 41, and can not prove that the other guide except that the content that is cited belongs to prior art.
The secondary activating flow path processing method that another embodiment of the present invention provides a kind of network side to initiate obtain the condition whether judgement QoS meets the demands in this method, and the entity that whether meets the demands according to described condition criterion QoS is GGSN.
In the present embodiment, GGSN obtains to judge that the condition whether QoS meets the demands has three kinds of approach.A kind of is to obtain decision condition from strategy and charging regulation function entity, and another kind is by pre-configured acquisition decision condition, also has a kind of GGSN of being oneself to generate decision condition.
GGSN can obtain decision condition from strategy and charging regulation function entity, and this condition can be carried at strategy and send in the message of GGSN with charging regulation function entity.
GGSN also can be by pre-configured acquisition decision condition.For example, can set QoS and be not less than 30% of initial requirement, or set and do not consult QoS.Certainly, also can be at the pre-configured different decision condition of different types of service.
GGSN can also oneself generate decision condition.GGSN can according in the ability of this GGSN, this GGSN present load, user signing contract information, operator pre-configured at least one generate the condition of judging whether QoS meets the demands.
