[0050] The first way is that the network instructs the terminal to save the dedicated identifier.

[0051] Specifically, the process includes: the RNC uses dedicated signaling to notify the terminal to enter the CELL_PCH state, and the above-mentioned signaling does not carry the terminal-specific identifier in the CELL_PCH state; then, the terminal receives the control signaling, and according to the system broadcast or in the dedicated signaling The dedicated identifier storage indicates to save the terminal identifier. Thereafter, if the terminal receives network downlink data or has uplink data transmission, it transfers to the CELL_FACH state, and uses the saved dedicated identifier to send E-RUCCH, etc.

[0052] Note that the above control signaling is RRC (Radio Resource Control) signaling, including system broadcast messages or dedicated signaling. That is to say, the instruction of saving the terminal identity is carried in the system broadcast or in the dedicated co...

[0067] The second way is that the terminal saves the dedicated identifier when certain conditions are met.

[0068] Specifically, different from the first method, the terminal does not need to wait for an instruction from the network, but judges whether it should save the terminal-specific identifier according to specific conditions.

[0069] Among them, specific conditions include:

[0070] 1) Both the terminal and the network support enhanced CELL_FACH and enhanced CELL_PCH. The specific process is: the terminal carries the enhanced CELL_FACH and enhanced CELL_PCH capability indications of the terminal through RRC signaling (RRC connection establishment request or RRC connection establishment completion or cell update), and notifies the RNC; the network carries the enhanced CELL_FACH and enhanced CELL_PCH through the system broadcast message block 5 Notify the terminal of configuration parameters (such as "HS-DSCH common system information", "Common E-DCH system info", "HS-...

Abstract

The invention discloses a method and system for storing a special identification of a terminal. The method comprises the following steps: step S102, a network sends a special control signaling to the terminal and notifies the terminal of entering a cell paging channel state; and step S104, when a preset condition is met, the terminal stores the special identification of the terminal under the original state. In the technical scheme disclosed by the invention, the time delay of state transferring can be reduced, the signaling overhead is saved and the method is simple and feasible.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for storing terminal-specific identifiers. Background technique [0002] According to the current agreement, there are four states in the terminal connection mode: cell dedicated channel (CELL Dedicated Channel, referred to as CELL_DCH) state, cell forward access channel (CELL Forward Access Channel, referred to as CELL_FACH) state, cell paging Channel (CELL Paging Channel, CELL_PCH for short) state and UTRAN-Registration-Area Paging Channel (UTRAN-Registration-Area Paging Channel, URA_PCH for short) state. [0003] In the CELL_DCH state, the terminal is assigned a dedicated channel or uses related channels and transmission mechanisms of High Speed ​​Downlink Packet Access (HSDPA) and High Speed ​​Uplink Packet Access (HSUPA) to transmit data. In this state, it can quickly Transfer large amounts of data. [0004] When the amount of data transmitted by the termina...
