Abstract

A method, system and related device for overriding low priority and/or Extended Access Bar (EAB) are disclosed. The method includes the following steps: an Open Mobile Alliance (OMA) Device Management (DM) server sends dual-priority User Equipment (UE) a low priority overriding indicator and/or an EAB overriding indicator; and the dual-priority UE determines whether to override low priority and/or EAB according to the low priority overriding indicator and/or the EAB overriding indicator. The disclosure determines an EAB processing manner of dual-priority UE, implements the NAS functional parameter management for the dual-priority UE, and facilitates the application and promotion of the dual-priority UE.

determining, by the dual-priority UE, whether to override low priority and/or EAB according to the low priority overriding indicator and/or the EAB overriding indicator.

2. The method according to claim 1, further comprising:

storing, by the dual-priority UE, the low priority overriding indicator and/or the EAB overriding indicator in a Universal Subscriber Identity Module (USIM) card.

3. The method according to claim 2, wherein determining, by the dual-priority UE, whether to override low priority and/or EAB according to the low priority overriding indicator and/or the EAB overriding indicator comprises that:

after the dual-priority UE initiates a low priority request to a 3rd Generation Partnership Project (3GPP) network side and under condition that the dual-priority UE has received an EAB rejection message from the 3GPP network side, if the dual-priority UE determines that the low priority overriding indicator and/or the EAB overriding indicator are/is in the USIM card, and the low priority overriding indicator and/or the EAB overriding indicator indicate/indicates permission to override the low priority and/or the EAB, then the dual-priority UE overrides the low priority and/or the EAB, and initiates a normal priority request to the 3GPP network side;

after the dual-priority UE initiates a low priority request to the 3GPP network side, and under condition that the dual-priority UE has received a rejection message carrying backoff time from the 3GPP network side, if the dual-priority UE determines that the low priority overriding indicator is in the USIM card, and the low priority overriding indicator indicates permission to override the low priority, then the dual-priority UE overrides the low priority, and initiates a normal priority request to the 3GPP network side;

or else, the dual-priority UE does not override the low priority, and fails to initiate a normal priority request to the 3GPP network side.

4. The method according to claim 3, before receiving, by the dual-priority UE, the EAB rejection message from the 3GPP network side, further comprising:

indicating, by a Mobility Management Entity (MME)/Serving GPRS Support Node (SGSN), an EAB parameter to an Evolved Node B (eNB) through Non Access Stratum (NAS) signalling; and

sending, by the eNB, an EAB rejection message to the dual-priority UE after receiving the indication, wherein the EAB rejection message indicates the EAB parameter.

5. The method according to claim 3, before receiving, by the dual-priority UE, the rejection message carrying backoff time from the 3GPP network side, further comprising:

determining, by the eNB or the MME/SGSN, backoff time, and sending a rejection message carrying the backoff time to the dual-priority UE.

6. The method according to claim 3, wherein the request that the dual-priority UE initiates to the 3GPP network side is a mobility management request or a session management request.

15. The method according to claim 4, wherein the request that the dual-priority UE initiates to the 3GPP network side is a mobility management request or a session management request.

16. The method according to claim 5, wherein the request that the dual-priority UE initiates to the 3GPP network side is a mobility management request or a session management request.

7. A system for overriding low priority and/or Extended Access Bar (EAB), comprising an Open Mobile Alliance (OMA) Device Management (DM) server, and dual-priority User Equipment (UE);

wherein

the OMA DM server is configured to send the dual-priority UE a low priority overriding indicator and/or an EAB overriding indicator; and

the dual-priority UE is configured to determine whether to override low priority and/or EAB according to the low priority overriding indicator and/or the EAB overriding indicator.

8. The system according to claim 7, wherein the dual-priority UE is further configured to store the low priority overriding indicator and/or the EAB overriding indicator in a Universal Subscriber Identity Module (USIM) card.

9. The system according to claim 8, further comprising a 3rd Generation Partnership Project (3GPP) network side;

wherein the dual-priority UE is specifically configured to, after initiating a low priority request to the 3GPP network side and under condition of receiving an EAB rejection message from the 3GPP network side, determine whether the low priority overriding indicator and/or the EAB overriding indicator are/is in the USIM card, and whether the low priority overriding indicator and/or the EAB overriding indicator indicate/indicates permission to override the low priority and/or the EAB;

if the dual-priority UE determines that the low priority overriding indicator and/or the EAB overriding indicator are/is in the USIM card, and the low priority overriding indicator and/or the EAB overriding indicator indicate/indicates permission to override the low priority and/or the EAB, then the dual-priority UE overrides the low priority and/or the EAB, and initiates a normal priority request to the 3GPP network side;

or else, the dual-priority UE does not override the low priority and/or the EAB, and fails to initiate a normal priority request to the 3GPP network side; and
