Embodiment 1

[0037] For the basic flow of the resource immediate assignment method in the first embodiment of the present invention, please refer to figure 1 , in this embodiment, a large number of terminals randomly initiate access requests, requesting the base station to allocate grouping resources for the terminals, and the base station receives the channel request messages sent by each terminal. The method for immediately assigning resources in this embodiment is:

[0038] Step 101: Construct an immediate assignment message according to channel request information of at least two terminals, the channel request information is used to instruct the terminal to request channel resources, and the immediate assignment message includes channel resources assigned to the at least two terminals respectively.

[0039] Specifically, the channel request information is a channel request message such as a channel request, a GPRS packet channel request, or an EGPRS channel request. The channel resourc...

Embodiment 2

[0049] see figure 2 , is a flow chart of the second embodiment of the resource immediate assignment method of the present invention. This embodiment describes the resource immediate assignment method in detail in conjunction with the terminal. After the terminal sends the channel request message, it starts to monitor the AGCH channel and obtains the resources allocated by the base station for itself. The grouping resources, the resource immediate assignment methods include:

[0050] In step 201, the terminal monitors an immediate assignment message allowing access to a channel, and the immediate assignment message includes resource parameters allocated to at least two terminals respectively.

[0051] In step 202, the terminal analyzes the offset value in the monitored immediate assignment message, and judges whether it has sent a channel request message on the frame number indicated by the offset value. If yes, it goes to step 203; if not, it goes to step 204.

[0052] Step ...

Embodiment 3

[0057] In this embodiment, the method for immediately assigning resources is described in detail in conjunction with the terminal, and the method for immediately assigning resources includes:

[0058] Each terminal sends channel request messages, for example, terminals A, B and C send channel request message 1, channel request message 2 and channel request message 3 on frame numbers 5, 6 and 7 respectively. After sending the channel request message, the terminal monitors the IA message for resource allocation on the AGCH channel.

[0059] See also figure 1 ,

[0060] Step 101, the base station calculates the offset value between the specified frame number of the downlink immediate assignment message and the frame number of the uplink request message of each terminal according to the frame number of the channel request message of each terminal.

[0061] Assuming that the specified frame number of the downlink immediate assignment message is 13, then the offset value from term...

Abstract

The embodiment of the invention discloses a method, device and system for assigning resource immediately. The method comprises the following steps of: building an immediate assignment message according to channel request information of at least two terminals, wherein the immediate assignment message assigns channel resource for the channel request message of the at least two terminals; and sending out the immediate assignment message. With application of the embodiment of the invention, one immediate assignment message can assign packet resources for at least two terminals under the condition that the effective bytes of the immediate assignment message are invariable, so that access requirements of more terminals are satisfied.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource immediate assignment method, device and system. Background technique [0002] When the terminal sends uplink data or initiates a circuit call, it needs to send a channel request message to the network on a random access channel (RACH, RandomAccess Channel), and the network assigns packet resources to the terminal. The method is specifically: the terminal sends a channel request message, and the channel The request message can be a channel request (Channel Request), a GPRS packet channel request (GPRS Packet Channel Request) or an enhanced data rate GSM evolution technology packet channel request (EGPRS Packet Channel request); the network receives the channel request message sent by the terminal, and The Immediate Assignment (IA, Immediate Assignment) message is fed back on the Access Granted Channel (AGCH, Access Granted Channel), so as to assign packet...
