Embodiment 1

[0127] Corresponding to the application scenario in which the foregoing method 1 is used to notify the eNB of the priority information of each MBMS service.

[0128] (1) Processing on the MCE side.

[0129] In the existing MBMS-related architecture, the MBMS control entity of the core network has notified the MCE node of the priority and service quality related information of each MBMS session.

[0130] Next, when the MCE node sends the MBMS Session Start Request message to the eNB through the M2 interface, it carries appropriate priority information and / or service quality requirement information and sends it to the eNB.

[0131] Or, when the MBMS service-related priority and / or service quality information changes, the updated service priority and / or service quality requirement information is carried in the MBMS Session Update Request message and sent to the eNB.

[0132] (2) Processing process on the eNB side.

[0133] The eNB receives the MBMS Session Start Request or MBMS...

Embodiment 2

[0138] Corresponding to the application scenario in which the foregoing method 1 is used to notify the eNB of the priority information of each MBMS service.

[0139] (1) Processing on the MCE side.

[0140] In this embodiment, the process of the MCE node notifying the eNB of the priority and / or service quality requirement information of each MBMS service is the same as the corresponding process in the first embodiment, and will not be described again.

[0141] (2) Processing process on the eNB side.

[0142] The eNB obtains the priority and / or service quality requirement information of each MBMS service from the MCE, performs comprehensive processing on the priority information of all MBMS services being transmitted under the cell, and obtains the total priority information of the MBMS services of the cell, possibly The way is as follows:

[0143] Record the highest priority among all the services being transmitted as the total priority of MBMS services under this cell;

[...

Embodiment 3

[0151] Corresponding to the application scenario in which the aforementioned method 2 is adopted, and the eNB is notified of the priority information of the overall MBMS service.

[0152] (1) Processing on the MCE side.

[0153] In the existing MBMS-related architecture, the MBMS control entity of the core network has notified the MCE node of the priority and service quality related information of each MBMS session.

[0154] Next, the MCE node needs to comprehensively process the priority information of the MBMS service already sent on the air interface / and the priority information of the MBMS service to be sent on the air interface to form an MBMS that can be notified to a specific cell of the eNB The total priority information of the service or the total priority information of the MBMS service based on the MBSFN Area, and the ways of comprehensively processing the priority are the various ways listed in Embodiment 2.

[0155] When the overall MBMS service priority informat...

Abstract

The embodiment of the invention discloses a method and equipment for processing the priority level of multimedia broadcast multicast service (MBMS). By applying the technical scheme of the embodiment of the invention, multicast cell equipment (MCE) sends information of the priority level of the MBMS through an interface M2, so that the base station can determine a priority level relation between single-cast service of corresponding cells and the MBMS according to the information of the priority level of the MBMS; and therefore, the base station acquires the information of the priority level of the MBMS allocated by a network top node. By the method and the equipment, the MBMS or the single-cast service can be retained rationally under the condition that the MBMS and the single-cast service are conflicted in receiving; and therefore, further congestion of the network side is avoided and a user experience is guaranteed.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and equipment for processing MBMS service priority. Background technique [0002] MBMS (Multimedia Broadcast Multicast Service, Multimedia Broadcast Multicast Service) is used to provide multimedia broadcast and multicast services for users in a wireless cell (Cell). In the current LTE (Long Term Evolution, Long Term Evolution) system, MBMS services are supported on a frequency layer shared by MBMS and unicast services, and cells on this frequency layer are mixed MBMS / unicast cells. A frequency layer capable of providing MBMS services is called an MBMS frequency layer. On an MBMS frequency layer, MBMS services use an MBSFN (Multicast Broadcast Single Frequency Network, multicast / multicast single frequency network) transmission mode. [0003] The so-called MBSFN refers to synchronous transmission in multiple cells with the same frequency at the same time (that is,...
