Problems solved by technology

[0035] In the non-QoS update process of the bearer initiated by the PDN GW, the MME notifies the eNodeB to modify the UE-AMBR to go through the subsequent independent UE context modification process, which increases the probability of network signaling interaction and bearer modification failure.

Embodiment 1

[0089] In this embodiment, the PDN GW initiates the non-QoS update of the bearer, and the MME takes the minimum value of the sum of the APN-AMBRs of all activated APNs and the subscribed UE-AMBR as the newly set UE-AMBR according to the modified APN-AMBR; When the newly configured UE-AMBR is inconsistent with the previously configured UE-AMBR, the MME sends the newly configured UE-AMBR in the downlink NAS transmission message to the eNodeB; AMBR modifies UE-AMBR. The method for bearing modification provided by this embodiment, such as Figure 5 shown, including the following steps:

[0090]Step 500, the PDN GW sends an update bearer request message to the S-GW, which carries the modified APN-AMBR;

[0091] Step 501, the S-GW sends an update bearer request message to the MME, which carries the modified APN-AMBR;

[0092] Step 502, after the MME receives the modified APN-AMBR carried in the update bearer request message, take the minimum value of the sum of the APN-AMBRs of a...

Embodiment 2

[0100] In this embodiment, the HSS initiates the subscription QoS update, and the MME takes the minimum value of the sum of the APN-AMBRs of all activated APNs and the subscribed UE-AMBR as the newly set UE-AMBR according to the modified APN-AMBR; When the UE-AMBR is inconsistent with the previously set UE-AMBR, the MME carries the newly set UE-AMBR in the downlink NAS transmission message sent to the eNodeB; the eNodeB modifies the UE-AMBR according to the newly set UE-AMBR in the downlink NAS transmission message. -AMBR. The method for bearing modification provided by this embodiment, such as Image 6 shown, including the following steps:

[0101] Step 600, the HSS sends an insert user data request to the MME, and the insert user data request carries a modified APN-AMBR;

[0102] Step 601, the MME sends an insert user data response to the HSS;

[0103] Step 602, the MME sends a modify bearer command to the S-GW, and the modify bearer command carries the modified APN-AMBR;...

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 [0001] The invention relates to the update technology of the packet domain and the evolution domain in the mobile communication system, in particular to a system and method for bearer modification. Background technique [0002] The project of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) for the next generation mobile wireless network is called System Architecture Evolution (SAE, System Architecture Evolution). The structure of SAE is as figure 1 As shown, it contains the following network elements: [0003] Evolved radio access network (E-RAN, Evolved RAN): It can provide higher uplink and downlink rates, lower transmission delay and more reliable wireless transmission; the network elements included in E-RAN are evolved base stations (eNodeB, Evolved NodeB), providing wireless resources for terminal access; [0004] Home Subscriber Server (HSS, Home Subscriber Server): permanently store user subscription data; [0005]...
