specific Embodiment approach 1

[0036] Specific implementation mode one: the following combination figure 1 This embodiment is described. In this embodiment, there is a method for improving channel utilization in overlapping coverage areas. It is assumed that terminal UE1 is attached to base station BS1, terminal UE2 is attached to base station BS2, terminal UE3 is attached to base station BS3, and the terminal UE1 and terminal UE2 both belong to group Group1, and terminal UE1 and terminal UE2 are in overlapping coverage areas of base station BS1 and base station BS2;

[0037] This method includes one or a combination of the following two forms:

[0038] The first form: including a call processing method on the calling side of a single call and a call processing method on the called side of a single call;

[0039] The call processing method of the calling side of the single call: the terminal UE1 is the calling terminal UE2, when the base station BS1 has no available service resources, the base station BS1 ...

specific Embodiment approach 2

[0045] Specific implementation mode two: the following combination figure 2 Describe this embodiment, this embodiment will further explain Embodiment 1, the call processing method of the calling side of a single call or the call processing method of the calling side of a group call specifically includes the following steps:

[0046] Step one one: the terminal UE1 sends a call application signaling to the base station BS1;

[0047] Step 1 and 2: The base station BS1 sends a call application signaling to the switching control center SCC with an unavailable service resource identifier;

[0048] Step 13: The switching control center SCC inquires whether the base station BS2 in the overlapping coverage area has available service resources; if yes, the switching control center SCC responds to the base station BS1 and carries an instruction handover identifier; otherwise, the switching control center SCC responds to the base station BS1 and carries an instruction call queuing ident...

specific Embodiment approach 3

[0051] Specific implementation mode three: the following combination image 3 Describe this implementation mode, this implementation mode will further explain implementation mode 1 or 2, the call processing method of the called side of the single call specifically includes the following steps:

[0052] Step 21: the terminal UE3 initiates a call application to the terminal UE1 to the switching control center SCC through the base station BS3;

[0053] Step 22: After the switching control center SCC determines that the base station BS1 has no available service resources, it inquires whether the base station BS2 in the overlapping coverage area has available service resources; if yes, the switching control center SCC sends an instruction handover identifier to the base station BS1, and notifies the terminal UE1 to handover ; Otherwise, the switching control center SCC answers the base station BS3 and carries the called no-resource identifier, and completes the called no-resource c...

Abstract

A method for improving channel utilization in overlapping coverage areas belongs to the technical field of communications. The invention aims to solve the problem that the called side cannot be processed in the existing method for using channels in overlapping coverage areas. It is assumed that terminal UE1 is attached to base station BS1, terminal UE2 is attached to base station BS2, and terminal UE3 is attached to base station BS3. Both terminal UE1 and terminal UE2 belong to group Group1, and terminal UE1 and terminal UE2 are located between base station BS1 and base station BS2. In overlapping coverage areas; the method of the present invention includes one of the following two forms or a combination of the two forms, the first form includes a single call calling side call processing method and a single call called side call processing method; the second The two forms include the call processing method of the calling side of the group call and the call processing method of the called side of the group call. The invention is used to improve the channel utilization rate in overlapping coverage areas.

Description

technical field [0001] The invention relates to a method for improving channel utilization in overlapping coverage areas in a cluster communication system, and belongs to the technical field of communication. Background technique [0002] At present, when the base station in the overlapping coverage area receives the terminal call application signaling, if there are available channel resources, the channel will be allocated to realize the call; if there is no available channel resource, the terminal call request will be queued, and if there is an available channel within the queuing validity period, the channel will be allocated Make the call. This method can only enable the terminal to implement call queuing or call preemption at the attached base station, which will lead to problems such as low utilization of wireless resources in overlapping coverage areas, and reduced user experience. [0003] In the existing design methods for realizing channel sharing of adjacent base...
