Abstract
The invention discloses a modification undertaking system. After a mobile management entity (MME) receives the modified access point name- aggregate maximum bit rate (APN-AMBR), the sum of the APN-AMBR of all activated APNs and the minimum value of the signed user equipment-aggregate maximum bit rate (UE-AMBR) are adopted as the newly set UE-AMBR; when the newly set UE-AMBR is inconsistent with the originally set UE-AMBR, a downlink network attached storage (NAS) transmission message which is sent by the MME to an evolved Node B (eNodeB) carries the newly set UE-AMBR; and the eNodeB modifies the UE-AMBR according to the newly set UE-AMBR in the downlink NAS transmission message. The invention simultaneously discloses a modification undertaking method. Through the scheme of the invention, when the modification is undertaken, the independent modification to the context of the UE does not need to be carried out, so that the chance of network signaling interaction and failure in modification undertaking is reduced.
Description
Technical field
The present invention relates to the renewal technology of packet domain and evolution territory in the mobile communcations system, relate in particular to a kind of system and method for bearing modification.
Background technology
Third generation partner program (3GPP, 3rd Generation Partnership Project) to the project of mobile wireless network of future generation System Architecture Evolution (SAE, System Architecture Evolution).The framework of SAE is as shown in Figure 1, has wherein comprised following network element:
The wireless access network of evolution (E-RAN, Evolved RAN): higher up-downgoing speed can be provided, lower transmission delay and reliable more wireless transmission; The network element that comprises among the E-RAN is evolution base station (eNodeB, Evolved NodeB), for the access at terminal provides Radio Resource;
Home subscriber server (HSS, Home Subscriber Server): permanent storage user contracting data;
Packet Data Network (PDN, Packet Data Network): for the user provides professional network;
The Packet Based Network of evolution (E-Packet Core): lower delay is provided, and allows more wireless access system to insert, comprised following network element:
Mobile management entity (MME, Mobility Management Entity): be the chain of command functional entity, the UE context is in charge of and is stored to the server of interim storaging user data, like UE/ ID, mobility management states, user security parameters etc.; And, when UE quarters at this tracing area or this network, be responsible for this UE is carried out authentication for the user distributes temporary mark; Handle all non-access layer informations between MME and the UE; Triggering is in the paging of SAE;
Serving GPRS Support Node (SGSN, Serving GPRS Support Node): support the GPRS that Gb or Iu insert, GMM context and PDP Context are in charge of and are stored to the server of interim storaging user data; All non-access layer informations between treatment S GSN and the UE;
Gateway (S-GW, Serving Gateway): be a user entity, be responsible for the user face data route and handle that termination is in the downlink data of the UE of idle condition; The SAE of management and storage UE carries (bearer) context, such as IP bearer service parameter and network internal routing iinformation etc., is the anchor point of 3GPP internal system user plane, and a user can only have a S-GW a moment;
Packet data network gateway (PDN GW): be responsible for the gateway that UE inserts PDN, distributing user IP address is the mobility anchor point of 3GPP and non-3GPP connecting system simultaneously, and the user can insert a plurality of PDN GW at synchronization.
Strategy takes regulation function entity (PCRF with adding up to; Policy and Charging RuleFunctionality): the service quality (Qos that mainly produces the control user data delivery according to the configuration information of business information and user signing contract information and operator; Quality of Service) rule and charging regulation also can be controlled the foundation and the release of carrying in the Access Network.
Physically, above-mentioned S-GW and PDN GW possibly lump together.
In the SAE system, the EPS qos parameter comprises carrying level qos parameter and carries the set tier qos parameter; Wherein,
It is following to carry the level qos parameter:

Distribute and keep priority (ARP; Allocation and Retention Priority); Be used for making decision and accept the foundation that still refusal carries or revise request in the situation of resource limit; Be used for when special resource limit, which decision abandons and carries, and includes: priority (Priority Level), seize capability flags (Pre-emption Capability) and seized ability (Pre-emption Vulnerability);
Maximum Bit Rate (MBR, Maximum Bit Rate): guarantee the Maximum Bit Rate that bit rate (GBR, GuaranteedBit Rate) carries can be provided;
GBR:GBR carries the assurance bit rate that can provide.
It is following to carry the set tier qos parameter:
APN-converge Maximum Bit Rate (APN-AMBR, Access Point Name-AggregateMaximum Bit Rate): the maximum rate of the set of all Non-GBR Bearer that pairing all PDN of APN connect;
Subscriber equipment-converge Maximum Bit Rate (UE-AMBR, UE-Aggregate Maximum Bit Rate): the maximum rate that the set of all Non-GBR Bearer of UE is corresponding.
In the SAE system, the minimum value of the APN-AMBR sum that MME gets all activated APN and signatory UE-AMBR is as the UE-AMBR that is provided with, so if there is the APN-AMBR of activation to change, may make the UE-AMBR that is provided with change.
In the SAE system; UE connects (PDN Connectivity) process and sets up default bearing through initiating to adhere to (attach) or PDN, or PDN GW sets up process and set up dedicated bearing for the user through initiating dedicated bearing, when above-mentioned carrying is set up; PCRF or PDN GW can carry for the user and distribute QoS or APN-AMBR; The QoS that follow-up PDN GW can initiate to carry upgrades, or initiates the non-QoS renewal of carrying, as upgrading APN-AMBR.
PDN GW initiates the non-QoS renewal process of carrying, and is as shown in Figure 2, comprises following step:
Step 200, PDN GW sends to S-GW and upgrades bearing request message, wherein carries the APN-AMBR of modification;
Step 201, S-GW sends to MME and upgrades bearing request message, wherein carries the APN-AMBR of modification;
Step 202; MME receives after the APN-AMBR of modification; The minimum value of the UE-AMBR that gets the APN-AMBR sum of all activated APN and contract is as newly-installed UE-AMBR; And whether more newly-installed UE-AMBR is consistent with original UE-AMBR that is provided with, and when inconsistent, institute in steps below executing; When unanimity, after the execution of step 207, process ends;
Step 203; When MME confirms that the user is in connected state; MME constructs descending Non-Access Stratum (NAS, Non Access Stratum) message transfer, and sends said descending NAS message transfer and give eNodeB; Said descending NAS message transfer carries Non-Access Stratum protocol Data Unit (NAS-PDU) message, and said NAS-PDU message comprises the APN-AMBR of modification;
Step 204, eNodeB receives descending NAS message transfer, and the APN-AMBR that revises in the NAS-PDU message is sent to UE, and notice UE accomplishes the bearing modification process, promptly notifies UE to accomplish APN-AMBR and revises;
Step 205, eNodeB sends up NAS message transfer and gives MME, wherein comprises NAS-PDU message;
Step 206, MME sends to S-GW and upgrades bearing response message;
Step 207, S-GW sends to PDN GW and upgrades bearing response message;
Step 208, MME sends UE contextual modifications request message to eNodeB, wherein comprises newly-installed UE-AMBR;
Step 209 after eNodeB revises the UE-AMBR of self according to newly-installed UE-AMBR, is sent UE contextual modifications response message to MME.
