Abstract

A method and system for determining a QoS of a WLAN service in a backhaul network are disclosed. The method includes: distinguishing whether a WLAN service or a WLAN instruction is to be returned, if the WLAN service is to be returned, recording a QoS of the WLAN service in a WLAN; and according to a preset mapping relation between the QoS of the WLAN service in the WLAN and a QoS of an ordinary service in the backhaul network, obtaining a QoS corresponding to a WLAN backhaul service in the backhaul network.

Claims

1. A method for determining a Quality of Service (QoS) of a Wireless Local Area Network (WLAN) service in a wireless backhaul network, comprising:

receiving, by the wireless backhaul network which is a mobile network, WLAN data sent from a WLAN used as terminal data of the wireless backhaul network;

determining, by the wireless backhaul network, whether the WLAN data needed to be returned is a WLAN service needed to be returned or a WLAN instruction needed to be returned;

if the WLAN data needed to be returned is the WLAN service, defining QoS property of the WLAN service, wherein the QoS property of the WLAN service comprises a subscription priority of a WLAN user and/or a WLAN service type, and determining a QoS of the WLAN service in the WLAN according to the QoS property of the WLAN service; and

according to a preset mapping relation between the QoS of the WLAN service in the WLAN and a QoS of an ordinary service in the wireless backhaul network, converting the QoS of the WLAN service in the WLAN into a QoS of the WLAN service in the wireless backhaul network;

wherein, the mobile network comprises a 3G mobile communication network or a Long Term Evolution (LTE) network.

2. The method according to claim 1, wherein

if multiple kinds of WLAN services needed to be returned exist, determining the QoS of the WLAN service in the WLAN comprises:

acquiring QoSs of all WLAN services needed to be returned in the WLAN;

performing a comprehensive assessment on all the acquired QoSs, wherein the comprehensive assessment includes;

summing, averaging or seeking an extreme value; and

recording a comprehensive assessment result as a final QoS of the WLAN services in the WLAN.

3. The method according to claim 2, wherein

if multiple kinds of QoS properties of the WLAN service needed to be returned exist, determining the QoS of the WLAN service in the WLAN comprises:

recording all the QoSs properties of the WLAN service;

comparing all the QoS properties, and performing negotiation, to obtain a negotiated QoS; and

recording the negotiated QoS as a QoS of the WLAN service in the WLAN.

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

if the WLAN data needed to be returned is the WLAN instruction, directly defining, by the wireless backhaul network, a QoS corresponding to the WLAN instruction in the wireless backhaul network.

5. The method according to claim 1, wherein

if multiple kinds of QoS properties of the WLAN service needed to be returned exist, determining the QoS of the WLAN service in the WLAN comprises:

recording all the QoSs properties of the WLAN service;

comparing all the QoS properties, and performing negotiation, to obtain a negotiated QoS; and

recording the negotiated QoS as a QoS of the WLAN service in the WLAN.

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

if the WLAN data needed to be returned is the WLAN instruction, directly defining, by the wireless backhaul network, a QoS corresponding to the WLAN instruction in the wireless backhaul network.

7. A system for determining a Quality of Service (QoS) of a Wireless Local Area Network (WLAN) service in a backhaul network, comprising:

an apparatus in a core network in a wireless backhaul network which is a mobile network, which comprises a processor and a memory, the memory having instructions executable by the processor to;

receive WLAN data sent from a WLAN used as terminal data of the wireless backhaul network;

determine whether the WLAN data needed to be returned is a WLAN service needed to be returned or a WLAN instruction is-needed to be returned;

if the WLAN data needed to be returned is the WLAN service, define QoS property of the WLAN service, wherein the QoS property of the WLAN service comprises a subscription priority of a WLAN user and/or a WLAN service type, and determine a QoS of the WLAN service in the WLAN according to the QoS property of the WLAN service; and

according to a preset mapping relation between the QoS of the WLAN service in the WLAN and a QoS of an ordinary service in the wireless backhaul network, convert the received QoS of the WLAN service in the WLAN into a QoS of the WLAN service in the wireless backhaul network;

wherein, the mobile network comprises a 3G mobile communication network or a Long Term Evolution (LTE) network.

8. The system according to claim 7, wherein

the QoS of the WLAN service in the WLAN is determined in a following way:

when multiple kinds of WLAN services needed to be returned exist, acquiring QoSs of all WLAN services needed to be returned in the WLAN;

performing a comprehensive assessment on all the acquired QoSs, wherein the comprehensive assessment includes;

summing, averaging or seeking an extreme value; and

recording a comprehensive assessment result as a final QoS of the WLAN services in the WLAN.

9. The system according to claim 8, wherein

the QoS of the WLAN service in the WLAN is determined in a following way:

when multiple kinds of QoS properties of the WLAN service needed to be returned exist, recording all the QoSs properties of the WLAN service;

comparing all the QoS properties, and performing negotiation, to obtain a negotiated QoS; and

recording the negotiated QoS as a QoS of the WLAN service in the WLAN.

10. The system according to claim 8, the processor of the apparatus is further configured to:

directly define a QoS corresponding to the WLAN instruction in the wireless backhaul network when the WLAN data needed to be returned is the WLAN instruction.

11. The system according to claim 7, wherein

the QoS of the WLAN service in the WLAN is determined in a following way:

when multiple kinds of QoS properties of the WLAN service needed to be returned exist, recording all the QoS properties of the WLAN service;

comparing all the QoS properties, and performing negotiation, to obtain a negotiated QoS; and

recording the negotiated QoS as a QoS of the WLAN service in the WLAN.

12. The system according to claim 7, the processor of the apparatus is further configured to:

directly define a QoS corresponding to the WLAN instruction in the wireless backhaul network when the WLAN data needed to be returned is the WLAN instruction.
