Embodiment 1

[0064] Embodiment 1 describes that through the S1 interface, the base station requests to obtain the service area indicator SAI list corresponding to a certain frequency of the neighboring base station, and the neighboring base station sends the SAI corresponding to the frequency to the requesting base station. Such as image 3 shown. The method may include the steps of:

[0065] Step 301: Base station 1 sends a message "MBMS information request" to MME, requesting to obtain the SAI list corresponding to the specific frequency of adjacent base station 2.

[0066] The base station 1 can obtain the cell identity and the frequency of the cell on the adjacent base station through the automatic neighbor cell establishment process, and discover a new cell. The process is as follows: the serving cell of the UE is the cell on the base station 1, the UE detects the information of the surrounding cells, and sends the detected physical cell identities of the surrounding cells to the se...

Embodiment 2

[0076] Embodiment 2 describes that through the S1 interface, the base station requests to obtain the SAI list corresponding to all the frequencies on the neighboring base station, and the neighboring base station sends the SAIs corresponding to all the frequencies on the base station to the requesting base station. Such as Figure 4 shown. The method may include the steps of:

[0077] Step 401: Base station 1 sends a message "MBMS information request" to MME, requesting to obtain the SAI list corresponding to all frequencies of adjacent base station 2.

[0078] The base station 1 can obtain the cell identifier and the frequency of the cell on the adjacent base station through the automatic neighbor cell establishment process, and discover a new cell. The process is as follows: the serving cell of the UE is the cell above the base station 1, the UE detects the information of the surrounding cells, and sends the detected physical cell identities of the surrounding cells to the...

Embodiment 3

[0093] Embodiment 3 describes that through the S1 interface, the base station sends the SAIs corresponding to all its frequencies to neighboring base stations, and the neighboring base station sends the SAIs corresponding to all its frequencies to the requesting base station. Such as Figure 5 shown. The method may include the steps of:

[0094] Step 501: Base station 1 sends a message "MBMS information request" to MME, requesting to obtain the SAI lists corresponding to all frequencies of adjacent base station 2.

[0095] The base station 1 can obtain the cell identifier and the frequency of the cell on the adjacent base station through the automatic neighbor cell establishment process, and discover a new cell. The process is as follows: the serving cell of the UE is the cell above the base station 1, the UE detects the information of the surrounding cells, and sends the detected physical cell identities of the surrounding cells to the serving cell. If the information of t...

Abstract

The invention provides a method for supporting broadcast data continuity. A base station acquires the frequency and SAI (Service Area Identification) information of an adjacent base station through an S1 interface, an X2 interface or an air interface and broadcasts the acquired frequency and SAI information. Therefore, the complexity of UE (User Equipment) processing can be reduced and continuous transmission of broadcast data is guaranteed.

Description

technical field [0001] The invention relates to multimedia broadcast multicast service (MBMS) technology, in particular to a method for supporting broadcast data continuity. Background technique [0002] figure 1 It is a system architecture diagram of System Architecture Evolution (SAE), where User Equipment (UE) 101 is a terminal equipment for receiving data. Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 102 is a radio access network including macro base stations (eNodeBs / NodeBs) that provide UEs with an interface to access the radio network. Mobility Management Entity (MME) 103 is responsible for managing UE's mobility context, session context and security information. Serving Gateway (SGW) 104 mainly provides user plane functions, and MME 103 and SGW 104 may be in the same physical entity. The packet data network gateway (PGW) 105 is responsible for functions such as charging and lawful interception, and may also be in the same physical entity as the SGW...
