Problems solved by technology

[0003] Through the above analysis, it can be seen that in the prior art, the base station allocates context resources for the terminal after receiving MSG1 sent by the terminal, and only after allocating context resources for the terminal, the base station can send MSG2 to the terminal; but in practical applications, Because the context resources in the base station are limited; and when the context resources of the base station have been allocated, the terminal cannot re-allocate context resources for the current terminal, and furthermore, the base station cannot send MSG2 to the current terminal; that is to say , when the context resources of the base station are all allocated, the base station cannot send MSG2 to the terminal
[0004] In the existing technology, after sending MSG1, the terminal will always wait to receive MSG2 sent by the base station; and if the terminal has not received MSG2 sent by the base station, the terminal will continue to send MSG1 messages periodically; it can be seen that using the existing technology In the method of allocating context resources, when the context resources of the base station are all allocated, the terminal will continuously send MSG1 to the base station, resulting in bursts of MSG1 and reducing the performance of the entire LTE system

Embodiment 1

[0055] The present invention provides a method for allocating context resources for a terminal, such as figure 2 As shown, the whole process is as follows:

[0056] Step S21: the terminal sends MSG1 (MESSAGE1, the first message) to the base station;

[0057] Step S22: the base station sends MSG2 (MESSAGE2, the second message) to the terminal;

[0058] In the embodiment of the present invention, when the base station receives the MSG1 sent by the terminal, it can specifically allocate an access identifier and air interface resources for the base station, and encapsulate the access identifier and air interface resources allocated for the terminal to generate a MSG2 message, And send the MSG2 message to the base station.

[0059] Step S23: the terminal sends MSG3 (MESSAGE3, the third message) to the base station;

[0060] In the embodiment of the present invention, when the terminal receives the MSG2 message sent by the base station, it can decapsulate the MSG2 message, and o...

Embodiment 2

[0073] In the LTE (Long Term Evolution, long-term evolution) system, the terminal and the base station can specifically use the Uu interface for communication, and in practical applications, such as image 3 As shown, the Uu interface protocol stack can be specifically divided into PHY layer (Physical Layer, physical layer), MAC layer (Medium Access Control Layer, medium access control layer), RLC layer (Radio LinkControl Layer, radio link control layer), PDCP layer (Packet Data Convergence Protocol Layer, packet data convergence protocol layer) and RRC layer (Radio Resource Control Layer, radio resource control protocol layer).

[0074] However, the method disclosed in Embodiment 1 can be specifically applied to the random access process of the terminal, such as Figure 4 As shown, the whole process is as follows:

[0075] Step S41: the terminal reports MSG1;

[0076] Step S42: After the MAC layer of the base station receives the above-mentioned MSG1, it allocates an access...

Embodiment 3

[0091] Corresponding to the above, the present invention also provides a device for allocating context resources for a terminal, such as Figure 5 As shown, the device includes:

[0092] The first sending unit 51 is configured to send a second message MSG2 to the terminal when receiving the first message MSG1 sent by the terminal;

[0093] The judging unit 52 is configured to, when receiving the third message MSG3 sent by the terminal, judge whether the number of terminals currently accessed by the base station reaches a maximum value; wherein, when the number of terminals accessed by the base station reaches a maximum value, the All context resources in the base station have been occupied, and the context resources are used to store information related to terminal communication;

[0094] The second sending unit 53 is configured to send an access rejection message to the current terminal when the number of the current access terminal reaches a maximum value.

[0095] Optiona...

Abstract

The invention discloses a method and a device for allocating context resources to a terminal. The method comprises steps: when a base station receives a first message MSG1 sent by the terminal, a second message MSG2 is sent to the terminal; when the base station receives a third message MSG3 sent by the terminal, whether the number of the current access terminals of the base station reaches the maximum value is judged, wherein when the number of the access terminals of the base station reaches the maximum value, all context resources in the terminal are all occupied, and the context resourcesare used for storing information related to terminal communication; and when the number of the current access terminals reaches the maximum value, the base station sends an access denial message to the current terminal. By adopting the method and the device of the invention, burst of the MSG1 can be avoided, and the performance of the whole LTE system is thus improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for allocating context resources for a terminal. Background technique [0002] In an LTE (Long Term Evolution, long-term evolution) system, when a terminal accesses a base station in a random access manner, such as figure 1 As shown, the whole process is as follows: first, the terminal sends MSG1 (MESSAGE1, the first message) to the base station, and when the base station receives the above MSG1, it will allocate context resources for the terminal, and the context resources are used to store related information of terminal communication, Then send MSG2 (MESSAGE2, the second message) to the terminal; and after the terminal receives the MSG2 sent by the base station, when there is a service demand on the terminal side, it can send MSG3 (MESSAGE3, the third message) to the base station; After MSG3, signaling connection resources can be alloc...
