lte - 成功完成ULA之后，为什么MME立即发送PUR(Why MME sends PUR right after successful ULA)

Question

We are working on an HSS project for a client, and are stuck on a strange issue.

(我们正在为一个客户进行HSS项目，但遇到了一个奇怪的问题。)

Right now we are in POC stage.

(目前我们正处于POC阶段。)

When we send ULA to MME, right after it, MME sends PUR to us for the same subscriber and the UE does not attach to 'network' (obviously).

(当我们向MME发送ULA时，紧随其后，MME向同一用户发送PUR给我们，而UE没有连接到“网络”（显然）。)

MME is not under our control (roaming partner), so we cannot get the logs from it.

(MME不受我们的控制（漫游伙伴），因此我们无法从中获取日志。)

We have tried to imitate ULA as per another working UE in the same roaming partner network (this connects to live HSS, not ours), and it did not work.

(我们试图模仿同一漫游伙伴网络中的另一个工作UE的ULA（这连接到实时HSS，而不是我们的HSS），但它不起作用。)

Can anyone please guide me what could be wrong?

(谁能指导我什么地方可能出问题了？)

Please let me know if you need more information.

(如果您需要更多信息，请告诉我。)

Answer 1

Take a good look at your ULA.

(好好看看您的ULA。)

Could be that you include in the ULA some unsupported data by MME

(可能是您在ULA中包含了MME不支持的数据)

I would suggest to check 3GPP TS 29.229 there is an AVP called Supported-Features which is included in the ULA and might be problematic to the MME.

(我建议检查3GPP TS 29.229，它有一个称为Supported-Features的AVP，它包含在ULA中，可能对MME造成问题。)
