Abstract
The invention provides a method for allocating resources in a state switching process. The method comprises the following steps that: a radio network controller (RNC) sends a radio link deleting request message to a node B when switching the cell dedicated channel (CELL DCH) state into the target state for a user, and the message carries indication information used for notifying the node B of releasing, keeping or allocating radio network temporary identity (RNTI) resources; and after receiving the radio link deleting request message, the node B determines to release, keep or allocate the RNTI resources according to the indication information carried by the message. The invention also provides a system for allocating the resources in the state switching process. By the system, the node B and the user can obtain and maintain the dedicated RNTI resources in the state switching process so as to provide support for the user to normally work at the target state.
Description
Technical field
The present invention relates to mobile communication system, relate in particular to resource allocation methods and system in a kind of state conversion process.
Background technology
3G (Third Generation) Moblie partnership (3GPP) has been finished the standardization effort that cell forward access channel (CELL_FACH) state strengthens in Wideband Code Division Multiple Access (WCDMA) access (WCDMA) system at present.The CELL_FACH state strengthens by introducing high speed descending sharing channel (HS-DSCH at the CELL_FACH state, High Speed Downlink Shared Channel) and strengthen special uplink channel (E-DCH, Enhanced uplink DCH) strengthens packet data transmission performance under the CELL_FACH state, to obtain less packet transfer delay and higher transmission rate.
After introducing enhancing CELL_FACH function, under the CELL_FACH state, data and control messages can be mapped to HS-DSCH and E-DCH goes up transmission.In order to support this transmission, HS-DSCH and the E-DCH resource information used under the pre-configured CELL_FACH state of Iub interface needs comprise the transmission bearer of Iub mouth and the resource that HS-DSCH, E-DCH are correlated with; And need distribute special-purpose HS-DSCH Radio Network Temporary Identifier (H-RNTI for each is in the user who strengthens under the CELL_FACH state, HS-DSCH Radio Network Temporary Identity) and special-purpose E-DCH Radio Network Temporary Identifier (E-RNTI, E-DCH Radio Network Temporary Identity), Node B (NodeB) and user will safeguard this two Radio Network Temporary Identifiers, are used for HS-DSCH and E-DCH transmission.
In the existing system, when the user uses HS-DSCH channel and E-DCH channel under cell private channel (CELL_DCH) state, dedicated H-RNTI is distributed by radio network controller (RNC) and sets up request message or wireless link reconfigured preparation message or wireless link reconfigured request message notice Node B by Radio Link, special E-RNTI is distributed by NodeB and is set up response message or wireless link reconfigured preparation response message or wireless link reconfigured response message notice RNC by Radio Link, and RNC notifies the user by idle message with dedicated H-RNTI and special E-RNTI subsequently again.When the RNC decision is moved out the CELL_DCH state with the user, can send the Radio Link deletion request message to NodeB, NodeB receives that the Radio Link deletion request message can discharge the special E-RNTI of having distributed and no longer safeguard the dedicated H-RNTI and the special E-RNTI of having distributed for this user.
Simultaneously, in the existing system, strengthening under the CELL_FACH state, owing to there is not Radio Link, the distribution mechanism of dedicated H-RNTI and special E-RNTI is different.When NodeB receives up CCCH (Common Control Channel, Common Control Channel) (uses public E-RNTI) after the message, use the common E-DCH Frame with Radio Resource control (RRC, Radio Resource Control) connection request message or cell update message send to RNC, carry the NodeB special E-RNTI of user's distribution for this reason in the E-DCH Frame; After RNC receives RRC connection request or cell update message, extract the special E-RNTI that NodeB distributes, and the user distributes dedicated H-RNTI for this reason, by HS-DSCH data frame type 2 E-RNTI of NodeB distribution and the H-RNTI of RNC distribution are carried to NodeB then,, connect by RRC simultaneously and set up message and notify the user at the corresponding relation that strengthens E-RNTI and H-RNTI under the CELL_FACH state for the NodeB maintenance customer E-RNTI and H-RNTI.Strengthening under the CELL_FACH state, because there is not Radio Link, the Iub mouth is introduced new signaling process: the User Status update command, be used for to discharge user's RNTI (when user's cell update arrives other sub-districts when the RNC decision, or RNC initiates RRC release), RNC uses this message informing NodeB to discharge user RNTI resource, and this message can once discharge a plurality of RNTI in the NodeB.
Distribution mechanism by existing system special E-RNTI and H-RNTI under the top two states, we can be very easy to find a problem, when RNC decision is moved into the user when strengthening the CELL_FACH state from the CELL_DCH state, this moment, RNC can send the Radio Link deletion request message to NodeB, distribution mechanism according to RNTI under the CELL_DCH state, if distributed RNTI before, this moment, NodeB received that the Radio Link deletion request message can discharge the RNTI that has distributed, and no longer safeguarded the corresponding relation of E-RNTI and H-RNTI; If do not distribute RNTI before, change enhancing CELL_FACH state over to from the CELL_DCH state after,, also have no idea at present to distribute the RNTI resource for the user of this moment according to above-described two kinds of RNTI resource allocation mechanisms.No matter which kind of situation takes place, and the result is when the user changes enhancing CELL_FACH state over to from the CELL_DCH state after, does not have available RNTI resource, also just can't carry out regular traffic.Also may there be this problem when in addition, the user is from the CELL_DCH state exchange to enhancing CELL_PCH state.
Summary of the invention
The technical problem to be solved in the present invention provides resource allocation methods and the system in a kind of state conversion process, be used for being in the user who strengthens CELL_FACH or CELL_PCH (cell paging channel) state behind the state exchange, can get access to special-purpose RNTI resource, thereby normally carry out transfer of data.
