Embodiment 1

[0160] Figure 7 It is a flow chart of implementing a method for modifying a multicast bearer for a scenario in which an eNB detects the start of multicast bearer congestion / overload according to a preferred embodiment of the present invention. Such as Figure 7 As shown, the process may include the following processing steps:

[0161] Step S702: Select a base station eNB that detects congestion / overload.

[0162] In this preferred embodiment, the entity performing the selection may be one of the following: selected by the MCE, selected by the GCS AS, or selected by the O&M. The above congestion / overload refers to the congestion / overload of the MBMS user plane data service, and the criterion for judging the congestion / overload needs to be formulated in advance and notified to the target eNB. Optionally, the judgment criterion may be carried in the indication information.

[0163] Under normal circumstances, if MBMS user plane data congestion / overload occurs in the MBSFN ar...

Embodiment 2

[0223] Figure 8 It is a flowchart of a method for modifying a multicast bearer in a scenario where an eNB detects the end of multicast bearer congestion / overload according to a preferred embodiment of the present invention. Such as Figure 8 As shown, the process may include the following processing steps:

[0224] Step S802: the eNB detects that the congestion / overload is over.

[0225] The end of congestion / overload means that the network returns to normal, for example, the user plane data load does not meet the preset congestion / overload conditions.

[0226] Step S804: the eNB sends recovery indication information to the AS.

[0227] The eNB can send congestion / overload indication information to the GCS AS through eNodeB (eNB)→MCE→MME→MBMS GW→BM-SC→AS.

[0228] The above congestion / overload indication information may include but not limited to at least one of the following:

[0229] (1) Congestion / overload identification;

[0230] (2) One or more cell identifiers, fo...

Embodiment 3

[0249] Figure 9 It is a flowchart of a method for modifying a multicast bearer in a scenario where an eNB periodically reports congestion / overload according to a preferred embodiment of the present invention. Such as Figure 9 As shown, the process may include the following processing steps:

[0250] Step S902: Select the eNB that reports congestion / overload.

[0251] Step S904: The eNB judges whether congestion / overload occurs within a preset period, if yes, go to step S906, otherwise, go to step S912.

[0252] The preset period is used for eNB to report indication information to AS. The preset period can be set by OAM or AS. Even if eNB does not detect congestion / overload within the preset period, eNB still needs to report indication information to AS.

[0253] The eNB detects the user plane bearer of the MBMS air interface, that is, whether congestion / overload occurs on the PMCH.

[0254] Step S906: eNB reports congestion / overload information to AS.

[0255] When the ...

Abstract

The invention discloses an indication information determination and processing method and device and a request message processing method and device. The indication information determination method includes the steps that whether user plane data of a multimedia broadcast multicast service (MBMS) bearer are congested or overloaded is determined, and first indication information is configured; the first indication information is sent to a group communication service (GCS) application server (AS), wherein the first indication information is used for providing reference data in the process that the GCS AS requests an MCE or an eNB to stop passing of cluster service, affected by the fact that the user plane data are congested or overloaded, of the MBMS bearer. According to the technical scheme, congestion or overload of the MBMS bearer can be relieved, so that influences on non-congestion or non-overload area UE are reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for determining and processing indication information and processing request messages. Background technique [0002] The trunking communication system is a dedicated wireless communication system developed to meet the command and dispatch needs of industry users and is oriented to specific industry applications. A large number of wireless users in the system share a small number of wireless channels, and the main application is command and dispatch. It is a multi-purpose, High performance wireless communication system. The trunking communication system has a wide range of application markets in the fields of government departments, public safety, emergency communications, electric power, civil aviation, petrochemical and military. [0003] The trunking communication system has experienced a development process similar to that of the cellular mobile communic...
