Description
Technical field
The present invention relates to wireless communication technology field more particularly to a kind of sides of WAVE communication device service communication coordinated
Method, relevant device and system.
Background technique
WAVE (Wireless Access in Vehicle Environment) technology is that the dedicated short distance of a new generation is logical
Believe (DSRC, Dedicated Short Range Communications) technology, is capable of providing the Che Chetong of high speed, low latency
Believe that (V2V, Vechicle to Vechicle), bus or train route communicate (V2I, Vechicle to Infrastructure), equipment room
D2D and building intelligent transportation system (ITS, Intelligent Transportation System) are communicated, to be applied to vehicle
Collaboration touch keep away, sleet section remind etc. traffic safety application and expressway tol lcollection (EFC, Electronic Fee
Collection), the technologies such as vehicle linking Internet.WAVE technical standard includes IEEE std 802.11p and IEEE std
1609 protocol suites, wherein IEEE std 1609.3 defines the transport services of WAVE technology, it is specified that media access control sublayer management
Entity (MLME, MAC subLayer Management Entity) and WAVE management entity (WME, WAVE Management
Entity function and corresponding service primitive), with the interaction for supporting upper layer network to apply.
ISP (Service Provider) and service user are introduced in IEEE std 1609.3
The concept of (Service User), is logical concept, it will be appreciated that is upper level applications.Play the part of the equipment of different role according to
The offer or use of the completion special services of operating process specified in agreement.
In the prior art, the WME-Notification.Indication primitive that Current standards define makes without normal direction service
The channel number of ISP, the 6th generation internet address (I Pv6, Internet is explicitly indicated in the upper layer application of user
Protocol Version 6), port numbers or physical address change, ISP turns after changing its information on services
And enter wait state, the data message for waiting service user to be received to send over, but at this point, service user can not define
The change information for getting information on services, still interacts according to former information on services, and so as to cause service disruption, interaction is limited,
Cause certain time delay.
Summary of the invention
The present invention provides method, relevant device and the system of a kind of WAVE communication device service communication coordinated, is able to solve
The service parameter of change can not be informed service user in real time when service parameter changes by ISP in the prior art,

Number variation, and determine that is, determination meets preset transmission there are when at least one destination service parameter in the service parameter changed
Notification condition then sends instruction service primitive to upper application entity, so that the upper application entity is receiving the finger
It after showing service primitive, according to the instruction service primitive, is sent to MIB and obtains service primitive, to obtain at least one described mesh
The corresponding destination service information of service parameter, and the confirmation service primitive returned according to the MIB received are marked, is updated corresponding
Information object service parameter, to complete the interaction of information, the confirmation service primitive carries the destination service information.
In the embodiment of the present invention, processing module 201 is sent after the WSA parsing that WME sends the 2nd WAVE communication equipment
Module 202 determines that is, determination meets preset hair there are when at least one destination service parameter in the service parameter changed in WSA
Notification condition is sent, Xiang Suoshu upper application entity sends the instruction service primitive for carrying at least one destination service parameter,
Realize and the service parameter of change informed into service user in real time, effectively reduce service user's aware service parameter change when
Reduction signaling overheads is extended to, for the upper application entity according to the instruction service primitive, it is former that Xiang Suoshu MIB sends the service of acquisition
Language to obtain the corresponding destination service information of at least one described destination service parameter, and is returned according to the MIB received
Confirmation service primitive, update the local service parameter set saved, to complete the interaction of information, effectively reduce because of clothes
Communication delay caused by business is interrupted improves the stability of user experience and service.
In fact, the preset transmission notification condition includes:
The service parameter of the variation includes the object of address, port numbers, channel number and the 2nd WAVE communication equipment
Manage at least one of address；
