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.

First claim

What is claimed is:

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.
