Problems solved by technology
The existing GPRS industry applications are mainly uplink data services. However, since the GPRS terminals commonly used in the current GPRS industry applications are in the 3+1 mode, it is necessary to allocate 3 uplink channels to users while allocating 1 uplink channel to users. The absolute number of downlink channels is relatively large, and it is easy to cause a lot of wireless channel resources to be wasted by users with uplink data traffic and high frequency of use. At the same time, their own data transmission rate will also decrease.

Embodiment Construction
[0027] In order to solve the problem that the existing data channel allocation method does not match the application of a large number of uplink data services, resulting in the waste of network resources, it is possible to replace or change the GPRS terminal of the 3+1 mode commonly used in the prior art or in the core Set relevant parameters on the network side, apply patches, etc. to realize the control of data channel allocation for specific GPRS users. But the inventor considers that the user group of the current GPRS industry is very large, and the number of mobile terminals used is huge. If starting from changing or changing the GPRS terminal, it needs to consume a lot of time, energy and material resources. Therefore, from changing or changing the GPRS Terminal approach is obviously not the best solution. Therefore, the inventor considers to solve the above-mentioned problems by setting relevant parameters on the core network side, applying patches, etc. to control the ...

The invention discloses a service processing method for a general packet radio service (GPRS) network. The method comprises the following steps: after receiving a packet data protocol (PDP) activation request sent by a mobile terminal, comparing the number of maximum uplink channels supported by the mobile terminal in multi-slot ability parameters of the mobile terminal with a maximum bit rate (MBR) parameter value of the mobile terminal; according to the comparison result, utilizing a smaller value of the number of the maximum uplink channels and the maximum bit rate MBR parameter value to update an MBR parameter value carried in the PDP activation request; and determining a data channel allocation mode according to the updated MBR parameter value, and allocating the data channels for the mobile terminal according to the determined data channel allocation mode. The invention also discloses a service GPRS support node SGSN, a packet control unit PCU and a GPRS network. The adoption ofthe invention can save the GPRS network resource.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a general packet radio service GPRS network and a data channel allocation method and device thereof. Background technique [0002] GPRS (General Packet Radio Service) technology is designed and developed for asymmetric uplink and downlink data services. Its main purpose is to increase the rate of downlink data services, and it has obvious advantages in downlink data services. [0003] In the GPRS industry, the PCU (Packet Control Unit, packet control unit) directly allocates PDCH (Packet Data Channel, packet data channel) resources according to the multi-slot capability attribute of the terminal. At present, GPRS industry applications generally use GPRS terminals set to 3+1 mode. The 3+1 mode means that GPRS terminals support 3 downlink time slots and 1 uplink time slot when performing data services. [0004] The application range of GPRS wireless data industry is becoming...
