Abstract
The invention provides an attribute consultation method which comprises the step of carrying out attribute consultation of an application layer protocol by a terminal and a base station through a common signal channel. The invention also provides an attribute consultation system. In the invention, the attribute consultation is carried out through the common signal channel, and thus the service interruption time is shortened and the user experience is improved.
Description
Technical field
The present invention relates to the communications field, relate in particular to attribute negotiation method and system when switching between broadcast multi-broadcasting and unicast mode in HRPD (high rate packet data) (High Rate Packet Data the abbreviates HRPD as) network.
Background technology
The follow-up evolution of code division multiple access (Code Division Multiple Access abbreviates CDMA as) network comprises two parts, and one is the enhancing of cdma20001x network, and another is the enhancing of HRPD network.The HRPD network strengthens introduces a plurality of enhancement techniques points at underlying protocol and upper-layer protocol, and the switching of broadcast multi-broadcasting and unicast mode is one of upper strata enhancement techniques point.
The switching of broadcast multi-broadcasting and unicast mode can guarantee that the user after shifting out the broadcast multi-broadcasting area of coverage, still can utilize unicast service channel broadcast listening multicast service under limited broadcast multi-broadcasting covering scene, keep favorable user experience.
For supporting the handoff functionality of broadcast multi-broadcasting and unicast mode, require terminal to perceive after the sub-district that will go to can not provide BroadCast MultiCast Service by the broadcast multi-broadcasting Overhead Message, can be with base station negotiate stream binding relationship and the association attributes relevant with BroadCast MultiCast Service, promptly with consulting not the homogeneous turbulence application class under the clean culture scene seemingly, BroadCast MultiCast Service is considered as a higher layer applications, for it consults the stream binding relationship and the association attributes of bottom, on the unicast service channel, receive the upper strata BroadCast MultiCast Service then.
Use in existing multithread grouping, strengthen in multithread grouping application and the multilink Multi-Flow Packet Application, all introduced new negotiation attribute ReservationKKBCMCSFlowIDAssociation (Reservation and BCMCS (BroadCast MultiCast Service) stream ID incidence relation attribute) at this function, ReservationKKBCMCSProgramIDAssociation (Reservation and BCMCS program ID incidence relation attribute), the BroadCast MultiCast Service stream that is used for using different broadcast-multicast flow ID type identifications carries out related with corresponding Reservation or goes related.Agreement allows to use GAUP (Generic Attribute Update Protocol is called for short GAUP, General attribute update protocol) flow process to carry out dynamic negotiation to above-mentioned two attributes.After finishing the negotiation of above-mentioned incidence relation attribute, also need to finish the negotiation of the stream association attributes that carries this upper layer application.
But in above-mentioned three grouping application protocols, the AttributeUpdateRequest corresponding with the GAUP flow process (attribute update request) message, AttributeUpdateAccept (attribute upgrades and accepts) message and AttributeUpdateReject (attribute upgrades refusal) message are defined as at present and can only send on preceding, reverse traffic channel, can not satisfy the realization of above-mentioned functions.Reason is, terminal is the broadcast listening multicast service under the sector, do not set up Traffic Channel with the base station, therefore terminal can't with the base station utilize above-mentioned message finish BroadCast MultiCast Service stream and Reservation incidence relation attribute and/or carrying upper layer application the stream association attributes negotiation, follow-up can only wait until that terminal shifts out the broadcast multi-broadcasting area of coverage after, be connected with other sectors are newly-built again, and negotiation above-mentioned parameter, and then open the application corresponding flow transmission and continue BroadCast MultiCast Service, so operation must bring the transmission delay of BroadCast MultiCast Service, influences user experience.
