Problems solved by technology

[0006] However, in the above three grouping application protocols, the AttributeUpdateRequest (attribute update request) message, AttributeUpdateAccept (attribute update acceptance) message and AttributeUpdateReject (attribute update rejection) message corresponding to the GAUP process are currently defined as only on the front and reverse traffic channels Send, and can not meet the realization of the above functions
The reason is that the terminal listens to broadcast and multicast services under the sector and does not establish a service channel with the base station. Therefore, the terminal cannot use the above message to complete the broadcast and multicast service flow related to the Reservation association attribute and / or the flow carrying the upper layer application. After the negotiation of attributes, the follow-up can only wait for the terminal to move out of the broadcast and multicast coverage area, and then create a new connection with other sectors, negotiate the above parameters, and then open the corresponding application streaming to continue broadcast and multicast services. Brings transmission delay of broadcast and multicast services, affecting user experience

Embodiment Construction

[0041] The present invention proposes to allow the terminal to complete the negotiation process of broadcast multicast service flow and Reservation association relationship attributes and / or flow-related attributes carrying upper-layer applications with the base station through the access channel and control channel in advance without establishing a service channel. When the subsequent terminal moves to an area where broadcast and multicast services cannot be provided, it can directly open the stream carrying broadcast and multicast services while establishing service channels with other sectors, which can reduce service interruption time and improve user experience.

[0042]The attribute negotiation method provided by the invention includes: the terminal and the base station perform attribute negotiation of the application layer protocol through a common channel.

[0043] Wherein, the common channel includes an access channel (AC) and a control channel (CC).

[0044] Wherein,...

Abstract

The invention provides an attribute negotiation method, which includes: the terminal and the base station perform attribute negotiation of the application layer protocol through a common channel. The invention also provides an attribute negotiation system. The present invention can perform attribute negotiation through public channels, reduce service interruption time, and improve user experience.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for attribute negotiation when switching between broadcast multicast and unicast modes in a High Rate Packet Data (HRPD) network. Background technique [0002] The subsequent evolution of the Code Division Multiple Access (CDMA for short) network includes two parts, one is the enhancement of the cdma20001x network, and the other is the enhancement of the HRPD network. HRPD network enhancement introduces multiple enhancement technology points for the bottom layer protocol and upper layer protocol, and the switch between broadcast multicast and unicast mode is one of the upper layer enhancement technology points. [0003] Switching between broadcast-multicast and unicast modes can ensure that users can still use the unicast service channel to listen to broadcast-multicast services after moving out of the broadcast-multicast coverage area in a limited broadcast-...
