Embodiment 1

[0025] Such as figure 1 As shown in , it is a schematic diagram of time slot and channel configuration of R4 single carrier in the prior art. Among them, TS0-TS6 represent time slot 1 to time slot 6. Depend on figure 1 It can be seen that TS1 and TS2 are uplink time slots, and TS3-TS6 are downlink time slots. Since the uplink and downlink time slot ratio of R4 single carrier in the prior art is 2:4, it is easy to cause the two downlink time slots TS3 and TS4 to be in the long-term Idle or low utilization state, resulting in waste of resources. Therefore, this embodiment provides a method for optimizing network capacity, aiming at figure 1 In order to solve the problem of the utilization rate of the R4 carrier, the R4 carrier is configured as follows: the main carrier (ie R4) in the TD-SCDMA network is modulated into a carrier shared by data and voice services, and the channel of the downlink idle time slot is changed to shared channel. Specifically, as figure 2 As shown...

Embodiment 2

[0057] In order to facilitate the implementation of the method in Embodiment 1, this embodiment provides a device for optimizing network capacity, which can be installed on the RNC in Embodiment 1, or the device can also be a kind of RNC, such as Figure 5 As shown, it includes: a configuration unit 51 , a judging unit 52 , and a carrier allocation unit 53 .

[0058] The configuration unit 51 is used to receive the configuration of modulating the main carrier in the TD network into a mixed carrier shared by data and voice services, and changing the channel of the downlink idle time slot into a shared channel;

[0059] A judging unit 53, configured to judge the type of the access service according to the access request;

[0060] The carrier allocation unit 53 is used for judging by the judging unit that the data service access request is received, according to the data service request in the cell where the mixed carrier has accessed the data service and the number of users who ...

Abstract

The invention discloses a method and a device for optimizing network capacity, relates to the technical field of communication and solves the technical problem of the limited TD network capacity in the prior art. The method comprises that a radio network controller (RNC) determines types of access services according to access requirements after main carriers in the Time Division-Synchronization Code Division Multiple Access (TD-SCDMA) network are modulated into data and voice service shared mixed carriers and channels of downlink free time slots are changed into shared channels; accessed carriers of data service access requirements are determined according to the ratio of the number of mixed carrier data service accessed users to the number of High Speed Downlink Packet Access (HSDPA) carrier data service accessed users in the community to be accessed. The method and the device are mainly used for improving the network capacity.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for optimizing network capacity. Background technique [0002] Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network system, referred to as TD network system adopts time division duplex (TDD) duplex mode, by adjusting the ratio of uplink and downlink time slots, it can be compared Good support for asymmetric services. Currently, the ratio of uplink and downlink time slots of mainstream carriers in the network is 2:4, that is, if there are slots TS1-TS6, among which, TS1 and TS2 are uplink time slots, then TS3-TS6 are downlink time slots. According to the time slot ratio, those skilled in the art can theoretically calculate the TD network capacity as follows: R4 (a carrier name for voice services) single carrier can accommodate 16 users, HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access, High Speed ​​Do...
