Embodiment Construction

[0025] In the embodiment of the present invention, after the terminal initiates enhanced access, the MAC layer selects an unallocated dedicated E-RNTI from the uplink enhanced dedicated channel radio network temporary identifier dedicated E-RNTI maintained by the MAC layer as the dedicated E-RNTI allocated to the terminal. RNTI, sending the context information including the dedicated E-RNTI allocated to the terminal to the RNC device. Since the MAC layer can select an unallocated dedicated E-RNTI from the dedicated E-RNTIs managed by the MAC layer as the dedicated E-RNTI allocated for the terminal, it can immediately send a message to the RNC device after the terminal initiates enhanced access. The context information of the selected dedicated E-RNTI reduces the access delay of the terminal.

[0026] Wherein, the solution of the embodiment of the present invention can be applied to HSPA+, and can also be applied to a system that needs to allocate a dedicated E-RNTI,

Abstract

The embodiment of the invention relates to the wireless communication technology field, especially to a method and equipment for sending context information. In the prior art, the context information can not be sent to RNC equipment by an MAC layer until the MAC layer has received a special-purpose E-RNTI distributed by an NBAP layer, so that time delay of access of a terminal is increased and an influence on business processing is exerted. However, the above-mentioned problem can be solved according to the invention. The method provided in the embodiment of the invention comprises the following steps that: after an MAC layer initiates reinforced access at a terminal, an undistributed E-RNTI for a special purpose is selected from special-purpose E-RNTIs maintained by the MAC layer and is used as a special-purpose E-RNTI distributed to the terminal; the MAC layer sends context information to RNC equipment, wherein the context information contains the special-purpose E-RNTI distributed to the terminal. According to the method provided in the embodiment of the invention, access delay of the terminal can be reduced, so that an affect of the access delay on business processing can be avoided, wherein the access delay is caused by distribution of special-purpose E-RNTIs.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for sending context information. Background technique [0002] After HSPA (High Speed ​​Packet Access, high-speed packet access) evolves to HSPA+, for eFACH (Enhance Cell_FACH, cell forward access channel status enhancement) dedicated E-RNTI (Ehanced Uplink Dedicated CHannel Radio Network Temporary Identifier, uplink enhanced Dedicated channel wireless network temporary identifier), NB (Node B, Node B) is responsible for the allocation of terminal dedicated E-RNTI, the 25.331 agreement stipulates that dedicated E-RNTI is unique in the entire NB, so the allocation of dedicated E-RNTI must be based on NB Assign to units. From the perspective of service QoS (Quality of Service, quality of service), it is necessary to quickly allocate dedicated E-RNTIs to minimize the time delay of dedicated E-RNTI allocations. [0003] The current scheme ...
