Problems solved by technology

[0005] Currently, only load factors such as the number of users and occupied bandwidth are considered when allocating DSPs. However, when UE (User Equipment, user equipment) establishes a signaling link, a protocol processing entity needs to be established. At this time, the service requirements of the UE are not known. However, the complexity of protocol entity processing and processing capability requirements vary with different UE services, resulting in different loads such as "CPU load and memory occupancy rate" of DSP.

Embodiment 1

[0050] Embodiment 1 of the present invention provides a DSP allocation method. The DSP is located on the service board of the RNC device, and there are multiple DSPs on the service board. Due to the variety of UE service types and different requirements for DSP processing capabilities, in order to avoid UE Unbalanced access leads to problems such as DSP stability and processing capacity reduction. The embodiment of the present invention needs to reasonably allocate a DSP (that is, one DSP among multiple DSPs) to the UE to balance the DSP load.

[0051] Such as figure 1 As shown, the DSP allocation method provided by the embodiment of the present invention includes the following steps:

[0052] Step 101, the RNC device receives an RRC (Radio Resource Control, radio resource control) establishment request message from a UE.

[0053] Wherein, when the UE needs to establish a signaling link, it will send an RRC establishment request message to the RNC device, and then the RNC dev...

Embodiment 2

[0078] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a distribution device for digital signal processing DSP, such as figure 2 As shown, the equipment includes:

[0079] A receiving module 11, configured to receive a radio resource control RRC establishment request message from a user equipment;

[0080] Determining module 12, is used for using described RRC establishment request message to determine RRC establishment reason;

[0081] An allocation module 13, configured to allocate a DSP to the user equipment according to the RRC establishment reason.

[0082] The RRC establishment reasons include: signaling type, circuit switching CS type, and packet switching PS type.

[0083] The determining module 12 is specifically configured to determine that the RRC establishment reason is CS when the RRC establishment request message carries emergency call information, or session-type called information, or session-type...

Abstract

The invention discloses a distribution method and equipment for DSP (digital signal processing), and the method has the following steps that: an RNC (radio network controller) receives an RRC (radio resource control) establishment request message from UE (user equipment), and determines an RRC establishment reason based on the RRC establishment request message; and the RNC distributes DSP for the UE based on the RRC establishment reason. In the embodiment of the invention, by determining the RRC establishment reason in a signaling link establishment process and distributing DSP for the UE according to the RRC establishment reason, load balance of the DSP on a service board can be realized and the operation stability of the service board can be improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a DSP (Digital Signal Processing, digital signal processing) distribution method and device. Background technique [0002] In the RNC (Radio Network Controller, radio network controller), the DSP on the service board is a local resource, which is the physical carrier for carrying user voice and packet data, that is, the protocol processing entity for processing voice and data in the RNC, which needs to be distributed On the DSP of the service board; therefore, the quality of the control and management of the DSP on the service board directly affects the utilization rate of the local resources of the RNC. It should be noted that there are multiple DSPs on each service board. [0003] In order to ensure that the protocol processing entities are evenly distributed on the DSPs of the service boards, in the prior art, the protocol processing entities are allocate...
