example 1

[0059] Figure 5 It is a flowchart of a method for allocating channel resources when a new R4 service is accessed according to an embodiment of the present invention, as shown in Figure 5 As shown, when there is a new R4 service access, the following steps S501 to S507 are included:

[0060] Step S501, when there is a new R4 service access, determine whether the remaining idle resources among the resources fixedly allocated to the R4 service at the frequency point where the new R4 service currently needs to be accessed can meet the resource requirements of the new R4 service, If it can be satisfied, go to step S507; otherwise, go to step S502.

[0061] Step S502, judging whether there is an MBMS time slot preempted by the R4 service on the frequency point that the new R4 service currently needs to access, if so, proceed to step S503; otherwise, proceed to step S504.

[0062] Step S503: Select the time slot to be allocated for the new service according to the selected scheme...

[0069] Image 6 It is a flow chart of a method for allocating channel resources in a new MBMS access according to an embodiment of the present invention, as shown in Image 6 As shown, when there is a new MBMS access, the following steps S601 to S609 are included:

[0070] Step S601, when there is a new MBMS access, judge whether the available remaining idle MBMS resource can meet the resource requirement of the new MBMS on the frequency point that the new MBMS needs to access currently, if so, proceed to step S609 , otherwise, go to step S602.

[0071] Step S602, judging whether there is an MBMS time slot that has been preempted by the R4 service on the frequency point that the new MBMS currently needs to access, if yes, proceed to step S603; otherwise, proceed to step S610.

[0072]Step S603: Select the time slot to be used for the new service according to the selected plan. If the above-mentioned plan 1 is adopted, in the MBMS time slot preempted by the R4 service, the re...

Abstract

The invention discloses a distribution method for the channel resource and a device thereof which are applied to the time division synchronous CDMA supplying resources for R4 service and multimedia broadcast / multicast service (MBMS). The distribution method comprises that if the remnant free resource in the time slot resource regularly distributed to the R4 service is lacking, and the free MBMS time slot resource which is distributed to the MBMS without carrying the MBMS exists in the communication system, the free MBMS time slot resource can be distributed to the R4 service. The method and the device improve the resource utilization rate, and enhance the capacity and the call completion ratio of the system at the same time.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a channel resource allocation method and device. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) introduces Multimedia Broadcast / Multicast Service (Multimedia Broadcast / Multicast Service, referred to as MBMS,) function in R6Release. MBMS is a shared network resource from a The technology of transmitting data from a data source to multiple targets realizes the sharing of network resources and improves the utilization rate of network resources (especially air interface resources). [0003] Since MBMS uses omnidirectional transmission in a cell, MBMS will cause serious interference to neighboring cells. In order to avoid neighbor cell interference, a Union Time-slot Network (UTN for short) networking mode may be used. For all cells belonging to a predetermined service area, the same MBMS da...
