Abstract

Embodiments of the present invention disclose a wireless service access method and apparatus. In the method, a group policy of a wireless access point AP and a group priority of a virtual access point VAP are configured, an access priority of a service access request of a user is determined according to the group policy of the AP and the group priority of the VAP, and a service access operation is executed according to the access priority. In the embodiments of the present invention, a differential QoS guarantee based on a user priority is provided, and QOS of a high priority user and a high priority service in a situation that wireless resources are constrained or environment is severe can be ensured.

the group-only refers to priority scheduling according to a group, and user services in a same group are scheduled in an FIFO (first-in-first-out) manner;

the group-wrr refers to priority scheduling according to a sending weight allocated to each group, and the group policy further carries a balance coefficient of each group, VAPs of each group obtain air interface wireless resources of the AP according to the balance coefficient of the each group, and service access requests in different groups of a same priority are scheduled in the FIFO manner;

the Service-first refers to scheduling where not only a service priority needs to be judged but also a same service is scheduled according to a group priority;

the group-first refers to that all data of a user in a high priority group enjoys a high priority, that is, user data in a low priority group can be sent or received only after data of the high priority user in the high priority group is completely sent or received, and users in groups of a same priority receive services in a round-robin.

2. The method according to claim 1, wherein the group policy of the AP is group-first;

the determining the access priority of the service access request and executing the service access operation according to the access priority comprises;

when wireless resources of the AP cannot satisfy the service access request of the user, and the user in a high priority group, discarding a service of a low priority group currently using the wireless resources of the AP, so as to release the wireless resources of the AP.

3. An access method of a wireless access point (AP), comprising:

receiving a packet sent by a user, wherein the user belongs to a virtual access point (VAP), the VAP joins a group, and the group comprises multiple VAPs;

obtaining a priority corresponding to the packet, wherein the priority corresponding to the packet is a priority of the group that the VAP joins;

sending the packet into a corresponding priority queue; and

sending packets in different priority queues corresponding to multiple groups according to a group policy of the AP;

wherein the group policy of the AP is any one of the following;

a group only scheduling policy (group-only), a group balance scheduling policy (group-wrr), a service-first scheduling policy (Service-first), and a group-first scheduling policy (group-first);

wherein,

the group-only refers to priority scheduling according to a group and user services in a same group are scheduled in an FIFO (first-in-first-out) manner;

the group-wrr refers to priority scheduling according to a sending weight allocated to each group, and the group policy further carries a balance coefficient of each group, VAPs of each group obtain air interface wireless resources of the AP according to the balance coefficient of the each group, and service access requests in different groups of a same priority are scheduled in the FIFO manner;

the Service-first refers to scheduling where not only a service priority needs to be judged but also a same service is scheduled according to a group priority;

the group-first refers to that all data of a user in a high priority group enjoys a high priority, that is, user data in a low priority group can be sent or received only after data of the high priority user in the high priority group is completely sent or received, and users in groups of a same priority receive services in a round-robin.

4. The method according to claim 3, wherein the group policy is group-first;

the determining the access priority of the service access request and executing the service access operation according to the access priority comprises;

when wireless resources of the AP cannot satisfy the service access request of the user, and the user in a high priority group, discarding a service of a low priority group currently using the wireless resources of the AP, so as to release the wireless resources of the AP.

5. The method according to claim 3, wherein the obtaining the priority corresponding to the packet further comprises:

obtaining a service type corresponding to the packet, to satisfy a requirement of the group policy of the AP that service scheduling according to the service type is involved.

6. The method according to claim 5, wherein the priority queues further comprises priority sub-queues corresponding to different service es.
