The PGW performs IP policy and 55 charging enforcement on packet flows to and from mobile 56 devices. 57 58 The SGW is a local mobility anchor for E-UTRAN mobility, 59 switching packets between the S5 interface and the GTP 60 based S1-U interface for mobiles in connected mode. 61 62 +------------------------------------------------+ 63 | | 64 | | 65 | +=======+__________ | 66 | | UTRAN | |S12 | 67 | | +======+ | | 68 | +======| | | | 69 | +======| SGSN |___ | | 70 | | +======+ || | 71 | | GERAN | | S4|| | 72 | +=======+ |(GTP-C|| | 73 | S3| VO,V1|| | 74 | | GTPU|| | 75 | |VO,V1)|| | 76 | +======+ || | 77 | ____| MME |__ || | 78 | | +======+ ||| | 79 | S1-MME| S11 ||| | 80 | | GTP-C ||| | 81 | | (V0,V1,V2) ||| | 82 |+====+ +========+ +======+ +======+ | +===+ 83 || UE |-|E-Utran | | SGW | | PGW |-SGi-|PDN| 84 || | |(EnodeB)| | | | | | | | 85 |+====+ +========+ +======+ +======+ | +===+ 86 | | | | GTP-C | | 87 | | | |(vo,v1,v2)| | 88 | | | |GTP-C | | 89 | | | | (vo,v1) | | 90 | | GTP v2-u | | | | 91 | ------------ ----------- | 92 | (S1-U) S5 | 93 | | 94 +------------------------------------------------+ 95 96 This architecture supports the non-roaming and roaming 97 architectures using GTP based protocol on the PGW and SGW 98 with a number of functions. It support high number of 99 subscribers with their associated control messages and 100 data traffic. Each of this association forms an entry in 101 PGW and SGW and is commonly know as bearers. 102 103 The various features used by this architecture and their 104 attributes are captured in this MIB: 105 106 1. Overload protection, handles congestion control, SGW and 107 PGW represent congestion as a DFP metric considering the 108 current CPU, memory usage and number of bearers open. On 109 reaching the low congestion threshold, based on the ARP, high 110 priority calls are accepted and those with a lower priority 111 are rejected. Once the high threshold is reached all new 112 calls are rejected. 113 114 2. Buffering agent, the SGW buffers the data packets in the 115 downlink direction till the downlink path/peer information is 116 ready. It buffers all packets coming from any gateway based 117 on the default/configured values of the buffer size, discard 118 period and number of packets. Packets will be buffered on a 119 per bearer basis and retrieved in the order it was buffered 120 using the handle given by the buffering agent initially. If 121 the buffer is full then no more bearers will be accepted. 122 123 Acronyms and terms: 124 125 3GPP 3rd Generation Partnership Project 126 DFP Dynamic Feedback Protocol 127 EDGE Enhanced Data
