Description
Technical field
The present invention relates to wireless access system, relate in particular to the processing method of terminal deviated from network in a kind of WiMAX system.
Background technology
WiMax is the standard of broadband wireless access, be a kind of based on 802.16 standards the technology of wireless MAN, it can provide towards the high speed of the Internet and connect.Different with current 2G, 3G technology, WiMax is a kind of completely based on the network of IP packet-switch technology, and the circuit-switched technology towards voice is not provided, therefore, to must adopt form in the enterprising lang sound communication of WiMax network based on the voice service on the IP (VoIP).802.16e be 802.16 standards under the mobile environment.
Owing to need in the WiMax network, carry multiple business, as voice, video, HTTP, Email or the like, and miscellaneous service is to the requirement difference of service quality (QoS), therefore in the WIMAX system, need the support of realization to QOS, promptly to the different business data of same portable terminal (MS), different service flow (service flow) is provided, as the service flow of a VOIP, the stream of a HTTP, and different service flow is specified different QOS parameters, thereby guarantee for different business provides different service quality.In WiMax, a SFID (service flow ID) is used to identify a service flow and all QOS parameters of service flow.
In current network working group (NWG) draft, the Wimax network architecture and Wimax QoS framework are respectively as shown in Figure 1 and Figure 2.In Wimax QoS framework, comprise with the closely-related entity of the present invention:
Management service flow device (SFM:Service Flow Management), situation according to local wireless sources and local other resource, service flow is carried out access control, it can carry out service quality (QoS) strategy that Internet Service Provider (NSP) issues such as flowing how many bandwidth etc. in advance for certain user (MS), and this functional entity is present in the base station (BS) in the access service network (ASN).
Service flow authorized person (SFA:Service Flow Authorization) comprises current service SFA and anchor point SFA, is responsible for giving corresponding service flow mandate, can approve service flow according to local policy.In real network, its corresponding physical entity can be Access Network gateway, base station controller, and it can carry out qos policy that NSP issues such as flowing how many bandwidth etc. in advance for certain user, and this strategy is handed down to SFM again, and this functional entity is present among the ASN.
Policy functional entity (PF:policy function), for grasping user profile and providing the entity of qos policy to it, it formulates various detailed qos policys, and this functional entity is present in the connectivity serving network (CSN:Connectivity Service Network).
The 3A server (AAA:Authentication, Authorization Accounting), are arranged in the server of CSN, be used to provide to the user authenticate, the function of authentication, charging.
Fig. 2 is the QoS frame diagram of portable terminal under roam mode, when portable terminal under non-roaming pattern, ASN will directly be connected with home network services provider (H-NSP:Home NSP), and without access network services provider (V-NSP:Visited NSP).
Shown in the QoS framework, aaa server in H-NSP deposit the user's " user QoS disposes (Subscriber QoS Profile) ", this configuration definition certain user's the qos parameter of various types of business, maximum as certain type of service allows bandwidth etc., is used to identify that the user uses the resulting QoS index of network.
Two kinds of feasible user QoS configuration process modes have been defined in the NWG draft standard at present, a kind of mode is, policing feature cognition obtains this configuration from AAA, according to this configuration user's service flow is carried out strategy decision and resource reservation by ownership policing feature body (H-PF); Another kind of mode is, in user authentication phase, this configuration can download among the service flow authorized person (SFA) among the ASN, according to this configuration user's service flow carried out that strategy determines and resource reservation judgement etc. by SFA.
Current NWG draft standard has defined user's free time (IDLE) pattern and to user's paging, idle pulley is a kind of low-power consumption mode of MS, and this pattern can reduce the energy consumption of MS.Comprise with IDLE pattern, the closely-related functional entity of paging in the current WiMax NWG draft standard:
Paging controller (PC:Paging Controller) is used for activity and the paging of the MS under the supervising the network IDLE pattern.PC is arranged in ASN, for the MS under each IDLE pattern, only there is a PC to manage its activity, be called anchor point PC (anchor PC), and might there be one or more PC to be used for relaying MS, be called relay PC (Relay PC) to the message between the anchor PC.
Paging agent (PA:Paging Agent) is arranged in ASN, is used for handling the mutual of the PC function executing relevant with paging with BS.
Location register (LR:Location Register), LR are distributed databases, and each LR is corresponding to a PC.Wherein deposited the information of the MS under the IDLE pattern.
As required, NAP can be divided into network several paging groups (PG:Paging Group), and a PG is made of one or more PA (BS), and is managed by network operator.A PG must reside within the NAP.It should be noted that a BS and relevant PA can be the entities among a plurality of PG.
Fig. 3 is existing WiMAX paging network configuration diagram.Under idle pulley, some important informations of MS will be retained among the LR that is associated with anchor point PC, and then the data path between BS and FA is with deleted.MS under the IDLE pattern can do periodic position and upgrade, and when the MS under the IDLE pattern passed through current PG border, enforceable position was upgraded and will be taken place.When the MS occurrence positions upgraded, MS can send a distance measurement request message (RNG-REQ) to network, and this message can be announced the present position of this MS of PC/LR.Therefore one to be in MS under the IDLE pattern should be addressable for network when any paging and position are upgraded.
Because MS might carry out shutdown (Power Down) operation under the Idle pattern, when MS carries out power-off operation, part as shutdown process, MS can send a distance measurement request message to network equally and upgrade to carry out the position, can comprise the information word prime implicant of " MS shut down indication " this moment in this message, shut down to inform PC/LR MS.
(Idle Mode System Timer) is overtime for system's idle timer on PC/LR, but PC/LR means that then MS has lost when still not receiving the location updating message of MS.Another kind of situation is, when the external agent (FA:Foreign Agent) of this MS receives the forward data bag of this MS, FA can notify PC/LR to carry out paging, yet when PC/LR has attempted predefined maximum paging number of times but still do not received the distance measurement request message of MS, mean that equally MS loses.
When PC/LR learns that MS shutdown or MS lose, the idle pulley that PC/LR can delete all these MS keeps information, yet the QoS information (comprising Subscirber QoS Profile and corresponding strategies etc.) that still may keep this MS user on the anchor point SFA of this MS, because the anchor point SFA of this MS and do not know that this MS shuts down or loses.
MS shutdown and lose and all mean the MS deviated from network, for the MS of deviated from network, anchor point SFA goes up and keeps the waste that its QoS configuration and policy information are undoubtedly a kind of resource.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, specific embodiments of the invention are elaborated below in conjunction with accompanying drawing.
The present invention is directed to the shortcoming of prior art, when PC/LR finds that MS leaves, send the anchor point SFA of this MS of message informing; Anchor point SFA can carry out the user QoS information delete procedure of (comprising QoS configuration and corresponding strategies) after receiving message, thereby the system resource of release busy improves resource utilization ratio.
Network side is found to be in and is taked following steps when MS under the IDLE pattern leaves:
A. anchor point PC/LR sends message and has preserved the anchor point SFA of the user QoS information (comprising QoS configuration and corresponding strategies) of this MS to this, to notify this SFA user deviated from network.This step comprises that anchor point PC/LR directly sends the anchor point SFA that this message sends to message by one or more relayings MS to anchor point SFA and the anchor point PC/LR of MS;
B. anchor point SFA responds above message, and this user's that will download user QoS information (as comprising QoS configuration and qos policy) deletion, and sends response message to anchor point PC/LR; This step comprises direct transmission and the handling process that sends by other relaying equally.
Fig. 4 is anchor point PC/LR directly sends a flow chart from message to anchor point SFA.In the present embodiment, defined two message: the user leaves indication (MS_Exit_Indication) and the user leaves response (MS_Exit_Response), the user leaves indication and the user leaves the information element (IE) that comprises in the response message and comprises MS ID (as the MAC Address of MS), is used to identify the MS of deviated from network.Wherein MS_Exit_Indication is used for anchor point PC/LR notice anchor point SFA user deviated from network; And being used for anchor point SFA, MS_Exit_Response receives the response that sends to anchor point PC/LR behind the MS_Exit_Indication.
Concrete flow process is as follows:
1) network be sure of to be in the MS deviated from network under the IDLE pattern, and its reason may be that MS loses (comprise paging failure or position upgrade overtime) or MS shutdown (Power down) etc.;
2) anchor point PC/LR sends MS_Exit_Indication message to the anchor point SFA of this MS, and notice anchor point SFA user is deviated from network;
3) anchor point SFA receives described MS_Exit_Indication message, and carries out the delete procedure of user QoS information;
4) anchor point SFA send MS_Exit_Response message to anchor point PC/LR with response as MS_Exit_Indication message;
About the message between anchor point PC/LR and the anchor point SFA, what more than adopt is MS_Exit_Indication and the MS_Exit_Response message that increases newly, this programme can also directly use existing message in the prior art in fact, can use the existing MS_Info_Request message of prior art to notify anchor point SFA as anchor point PC/LR, and anchor point SFA can use MS_Info_Response message to send response to anchor point PC/LR, optionally, can increase an IE in this message is used to indicate the user to exit network.
Anchor point PC/LR might not need directly to send this MS_Exit_Indication message to anchor point SFA, anchor point PC/LR can transmit this message by one or several relayings (as FA or other functional entity of this MS) and give anchor point SFA, and same MS_Exit_Response message also can send to anchor point PC/LR by one or more relayings.With FA as shown in Figure 5 as the handling process of relay function.
As the replacement scheme of the foregoing description, described anchor point PC/LR can directly not send message to the anchor point SFA of MS with notice anchor point SFA.But anchor point PC/LR sends message to certain functional entity among the NAP (may be FA or other entity of this MS), notifies this MS to lose; Notify the anchor point SFA of this MS again by this functional entity.Specifically comprise the steps:
When leaving (comprise MS lose and shut down) when anchor point PC/LR finds certain MS, the anchor point PC/LR of MS sends MS and leaves indication (MS_Exit_Indication) message to the functional entity (can be FA or other entity of this MS) among the NAP, announces this MS and loses; Anchor point PC/LR is sent to the MS_Exit_Indication message of the message of functional entity (as FA) for redetermination of the present invention in the present embodiment, also can come the instruct MS deviated from network in addition by adding an information element (IE) in the existing message in present draft, as MS_Info_Request message,, functional entity can be MS_Info_Response message and sending to the response message of anchor point PC/LR.
Transmission MS left response message to anchor point PC/LR after functional entity was received this message, and the message (MS_Exit_Indication) that the user of transmission indication simultaneously leaves is to anchor point SFA, to notify this anchor point SFA; The message that described functional entity (as FA) is sent to SFA also can as R3_Session Release Request message, optionally, can increase an information element (IE) for existing message in the present draft in the message, come the instruct MS deviated from network.Because anchor point SFA and the FA of MS may be on the same physical entity, then in this case, FA need not send the anchor point SFA of message informing MS.
Anchor point SFA receives and the described Indication message that leaves, and the user QoS information of deleting described MS, sends response message simultaneously to this functional entity, thereby realizes the deletion of MS user QoS information.
Need two groups of message to finish this handling process when carrying out this programme:
(1) anchor point PC/LR notifies that certain functional entity MS left leave Indication message with and response message, response message sends to anchor point PC/LR by functional entity;
(2) functional entity notify this MS anchor point SFA leave Indication message and response message thereof, response message sends to functional entity by anchor point SFA.
Wherein message (1) is used between anchor point PC/LR and the functional entity; Message (2) is used between functional entity and the anchor point SFA.And (1) by anchor point PC/LR be sent to functional entity leave the message that functional entity in Indication message and (2) is sent to anchor point SFA can be identical, also can be different.
In sum, anchor point PC/LR finds to be in the MS deviated from network under the IDLE pattern, send out message timely and give the anchor point SFA of the user QoS configuration of having preserved this user, so that anchor point SFA knows user's deviated from network, can delete the garbage on the SFA timely thus, as user QoS configuration and/or strategy, discharged system resource, improved usage factor of system resource.
The present invention is not only applicable to the WiMAX system, also is equally applicable to other wireless access system.
Above embodiment only is used to illustrate the present invention, but not is used to limit the present invention.Within the spirit and principles in the present invention all, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
