Description
Technical field
The present invention relates to the mobile communication technology field, be particularly related to TD SDMA (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) technology, relate in particular to a kind of in base station the method and system of allocating cell frequency.
Background technology
The TD-SCDMA standard that China proposes formally becomes one of global 3G standard.Communications network system based on this standard carries out commercial stage at home at present.
When the TD-SCDMA standard is formulated at first, only consider in a residential quarter to support a frequency.Under this scheme, the user capacity of residential quarter is very limited, and therefore follow-up introducing multi-frequency-point community, namely support a plurality of frequencies in a residential quarter, to enlarge residence user content.
For configuration and the report method of multi-frequency-point community logical resource in base station (Node B), " 2GHzTD-SCDMA digital mobile cellular telecommunication net height speed upstream packet access Iub interface specification requirement the 4th part: NBAP signaling message part " the 10th chapter provides as follows:
Processing resource to multi-frequency-point community in Node B (being logical resource) continues to continue to use the definition in base station application part agreement (NBAP, NodeB Application Part) agreement, and this definition comprises following content:
1, by the processing resources definition of a multi-frequency-point community in Node B, be a home cell (Local Cell), home cell has local district identification (Local Cel lID);
2, the processing resource (being logical resource) in Node B is defined as a frequency processing unit (Frequency Process Module) to a frequency, and the frequency processing unit has frequency processing unit sign (Frequency Process Module ID).
Each frequency processing unit belongs to and only belongs to a home cell, and it should be unique that the frequency processing unit is identified in the home cell under it, but between different home cell, can have identical frequency processing unit.
The foundation of existing residential quarter and reconfiguration course as shown in Figure 1, comprise the steps:
Step S101:NodeB is to radio network controller (RNC, Radio Network Controller) send checking response message or resource status indication (RSI) message, in this resource status Indication message or checking response message, carry the frequency processing unit sign that NodeB supports.
Step S102:RNC issues residential quarter to described NodeB and sets up request message (Cell SetupRequest), and described residential quarter is set up in request message and carried all configurable frequency point information.
Step S103:NodeB, from the configurable frequency point information of receiving, selects a frequency point information as main frequency point information, and to RNC, sends the residential quarter carry described main frequency point information and set up response message (Cell Setup Response).
Step S104:NodeB sends the resource status Indication message to RNC, in this resource status Indication message, carries other frequency point information except main frequency point information in described configurable frequency point information.
So far completed the process of setting up of single-frequency point residential quarter.Wherein in step S102, residential quarter is set up in request message also can only carry a main frequency point information, and step S103 NodeB sends after response message is set up in residential quarter and no longer performs step S104.
After the single-frequency point residential quarter is set up, if in this residential quarter, increase new frequency, further carry out following steps:
Step S105:NodeB sends resource status Indication message or checking response message to RNC, in this resource status Indication message or checking response message, carries newly-increased frequency processing unit.
Step S106:RNC receives this resource status Indication message or checking response message, obtains the not yet frequency point information of configuration, supposes to get altogether three frequency point information, is called frequency point information A, frequency point information B and frequency point information C; Then RNC sends to NodeB the cell re-configuration that carries frequency point information A and puts request message (Cell Reconfig Request).
Step S107:NodeB is according to frequency point information A allocating cell frequency, and to RNC, returns to cell re-configuration and put response message.
Step S108:RNC sends to NodeB the cell re-configuration that carries frequency point information B and puts request message.
Step S109:NodeB is according to frequency point information B allocating cell frequency, and to RNC, returns to cell re-configuration and put response message.
Step S110:RNC sends to NodeB the cell re-configuration that carries frequency point information C and puts request message.
Step S111:NodeB is according to frequency point information C allocating cell frequency, and to RNC, returns to cell re-configuration and put response message.
Can find out that from above flow process the foundation of residential quarter and reconfiguration course are exactly in fact the process that the frequency point information to residential quarter is configured.In residential quarter, set up during response message, cell re-configuration put response message, checking response message and state resource indicator message, all need to carry frequency point information.
Subdistrict frequency point allocation plan of the prior art has following shortcoming:
One, a piece of news can only carry a frequency point information.In a checking response message or cell re-configuration are put request message, can only carry a frequency processing unit sign, according to the definition of frequency processing unit sign, can only in residential quarter, set up a frequency.Under this restriction, by residential quarter, set up process and can only set up the single-frequency point residential quarter.If need to set up multi-frequency-point community, need single-frequency point residential quarter of model, then RNC puts the mode of message and indicates NodeB to set up each newly-increased frequency by repeating to send many cell re-configurations.
Two, in message, can not carry the band limits that frequency is supported.
The domestic frequency range of distributing at present TD-SCDMA is divided into three sections: A frequency range, B frequency range, F-band require Node B can realize supporting simultaneously the ability of multifrequency point.In present audit and resource status Indication message, only support to report frequency processing unit sign, and do not support the band information that reports the frequency processing unit corresponding.Can cause like this RNC on processing, to have some efficiency.For example, after the Node B that supports multiband reported idle frequency unit, RNC did not know which frequency range it supports, while therefore processing, need in each frequency range, choose a frequency point information and attempt, and according to present case, needed at most to repeat 3 ability successes.
Above shortcoming has caused the configuration flow of existing multi-frequency-point community more loaded down with trivial details jointly, and holding time is longer, and efficiency is not high.
