Description

Terminal business processing method and device

Technical field

The present invention relates to the field of communications, and in particular to a method and apparatus for processing business continuity of a terminal.

Background technique

The Multimedia Broadcast Multicast Service (MBMS) is an important feature introduced by the 3rd Generation Partnership Project (3GPP) in the R6 version. It is implemented from the data source. A point-to-multipoint service in which multiple users transmit data simultaneously in a specific range, so that resources of the network (including the core network and the access network) are shared, and a small number of resources are simultaneously provided for a large number of users with the same requirements. Business (eg multimedia business, etc.). The MBMS in Long-Term Evolution (LTE) is called Enhanced Multimedia Broadcast/Multicast Service (Evolved-MBMS, referred to as eMBMS). The R6 version supports high-speed downlink packet access (High Speed Downlink Packet). Access, referred to as HSDPA for short) or High Speed Uplink Packet Access (HSUPA for short).

A Multicast Broadcast Single Frequency Network (MBSFN) synchronization area is an area capable of performing MBSFN transmission. All eNodeBs in the area (Evolved Node B, e.g., eNodeB or eNodeB) The eNB, the name of the base station in the LTE system, can all be synchronized and perform MBSFN transmission.

The MBSFN area refers to a group of cells that implement MBSFN transmission by coordination. For the user equipment (User Equipment, UE for short) that receives the MBSFN transmission, the entire MBSFN area is regarded as one MBSFN cell.

The Multi-cell/Multicast Coordination Entity (MCE) is a logical entity introduced by the access network to implement multi-cell transmission (that is, using MBSFN transmission mode). When performing multi-cell transmission, it is responsible for MBSFN. The radio resources of all eNodeBs in the area are allocated and managed.

The MBMS control message is transmitted in two logical channels, namely, a Broadcast Control Channel (BCCH) and a Multicast Control Channel (MCCH). A small part of the information is in the BCCH (SIB13). On the uplink transmission, the UE first obtains the configuration and scheduling information of the MCCH from the BCCH, and then obtains the multicast traffic channel (Multicast Transaction) through the MCCH (System Information Block (SIB) 2/MBSFNAreaConfiguratuon signaling). Channel, referred to as MTCH, which may also be referred to as MBMS point-to-multipoint traffic channel configuration and scheduling information, ultimately decodes the MBMS data.

In the MCE centralized management base station network deployment, the base stations that belong to the same MBMS service area but do not belong to the same MBSFN area may have a certain service disconnection in the eMBMS service continuity for the mobile UE.

Aiming at the problem that the UE in the mobile in the related art is prone to poor service continuity in the handover process of the base station, an effective solution has not been proposed yet.

The process of switching from the source base station to the target base station is within the protection scope of the embodiment of the present invention.

Optionally, the foregoing service configuration information is obtained by using one of the following methods:

First way

The source base station receives a link setup request from the target base station, where the link setup request carries the service configuration information.

In order to better understand the method for obtaining the service configuration information by the source base station, the following describes a preferred embodiment:

This embodiment provides a process for acquiring an MBSFN area configuration (MBSFNAreaConfiguration) information of an adjacent base station in the initial stage of establishing an inter-eNodeB link, as shown in FIG. 2 .

The embodiment of the present invention is applied to the initial establishment of the link between the eNB a and the eNB b, and the specific process is as follows:

S201, after the two eNodeBs (including the eNB a and the eNB b) are established through the Simple Control Transmission Protocol (SCTP) link, the eNB a initiates a setup request, that is, the link establishment request of the foregoing embodiment, where It is assumed that eNB a sends an X2 setup request (X2SETUP REQUEST) to eNB b. At this time, the X2 SETUP REQUEST request signaling carries the MBSFNAreaConfiguration information of the eNB a. In the embodiment of the present invention, the MBSFNAreaConfiguration information is the service configuration information.

For the "X2SETUP REQUEST" in step S201, the following can be specifically described as follows:

The X2SETUP REQUEST message is sent by the base station to the neighboring base station to transmit initialization information for the network transport layer connection, where TNL is an abbreviation of the Transport Network Layer network transport layer;

The direction is from base station a to base station b.

S203, after receiving the X2 SETUP REQUEST request information, the eNB b stores the MBSFN area configuration (MBSFNAreaConfiguration) information configured on the eNB a locally; and reads the locally configured MBSFNAreaConfiguration information, and generates an X2 SETUP RESPONSE signaling. .

The "X2SETUP RESPONSE" in step S203 can be specifically described as follows:

The X2SETUP RESPONSE message is sent by the base station to the neighboring base station to transmit initialization information for the network transport layer connection.

The field attribute carried in the Served Cell Information structure carried by the X2SETUP RESPONSE signaling is the same as the MBSFNAreaConfiguration information related to the eNB a.

S205. The eNB b sends an X2 SETUP RESPONSE to the eNB a.

S207. The eNB a parses the received X2 SETUP RESPONSE signaling, and saves the related MBSFNAreaConfiguration information of the eNB b configuration to the local.

In this embodiment, the X2 SETUP REQUEST signaling in S201 and the X2 SETUP RESPONSE signaling in S203 all carry the MBSFNAreaConfiguration information configured by the eNB a, wherein the structure after the MBSFNAreaConfiguration information is added in the X2 protocol is listed in the following Table 1. The content added in the embodiment of the present invention is the content added in the embodiment of the present invention, that is, the information added in the embodiment of the present invention after the information in the physical multicast channel configuration list (PMCH Configuration List), wherein The PMCH is a physical multicast channel, which is an abbreviation of the Physical Multicast Channel.

S303, the eNB a saves the changed MBSFNAreaConfiguration information of the eNB a to the local area, and encodes the information into the base station configuration update (ENB CONFIGURATION UPDATE) signaling, where the ENB CONFIGURATION UPDATE is the update signaling in the foregoing embodiment.

In this embodiment, the SMB needs to encode the MBSFNAreaConfiguration information locally configured by the eNB a into the ENB CONFIGURATION UPDATE signaling to notify the eNB b. Since the ENB CONFIGURATION UPDATE signaling in the related protocol does not include the MBSFNAreaConfiguration information, The ENB CONFIGURATION UPDATE signaling is extended to add the MBSFNAreaConfiguration information.

S305. The eNB a sends the ENB CONFIGURATION UPDATE signaling to the eNB b.

S307. After receiving the ENB CONFIGURATION UPDATE signaling, the eNB b obtains the relevant MBSFNAreaConfiguration information of the eNB a configuration carried in the signaling, and saves the information to the local.

S309, the eNB b sends an ENB CONFIGURATION UPDATE ACKNOWLEDGE message to the eNB a.

It should be noted that the “ENB CONFIGURATION UPDATE” information involved in step S303 can be roughly described as follows: the base station configuration update message is sent by the base station to the peer base station to transmit update information for the network transport layer association;

In order to better understand the workflow of the business continuity processing of the above terminal, the following describes another preferred embodiment:

A preferred embodiment of the present invention provides a specific process for redirecting a source eNodeB (eNB a) to a target eNodeB (eNB b) in a cell redirection procedure, as shown in FIG.

S801. The eNB a sends a Measurement Control message to the UE.

S803. The UE sends a Measurement Report message to the eNB a.

S805, based on UE measurement, or load control reasons, the eNB a decision needs to be redirected to the eNB b. The MBSFNAreaConfiguration information of the local target cell is filled in the relevant field to be encoded. At this time, the eNB a sends the RRCConnectionRelease signaling to the UE to notify the UE to release the relevant air interface resource with the source base station, and the signaling further carries the UE redirecting eNB. The multicast MBSFN subframe configuration of b and the MTCH configuration of multicast. After the UE accesses the eNB b, the service that is being received by the source cell can be continued through the M1 interface, and the system message block does not need to wait for the system message of the SIB of the target cell, and the system message block carries the MBSFN subframe configuration of the multicast of the target cell. Multicast MTCH configuration.

In this embodiment, in the S801, the MBSFNAreaConfiguration information of the eNB b configuration that is locally saved by the eNB a needs to be encoded into the RRCConnectionRelease signaling, so as to notify the terminal that the frequency and physical cell identifier (Identity required) in addition to the eNB b are required. In addition to the bandwidth and the bandwidth, the MBSFNAreaConfiguration information of the redirected eNB b is also required to be encoded, and the M subframe configuration of the multicast and the Mtch configuration of the multicast can be obtained through the X2 interface.

In summary, in order to effectively reduce the delay of the service, in the implementation of the current base station, the base station (source base station) adds the MBSFNAreaConfiguration information of the neighboring base station (the target base station), such as the MBSFN Subframe and the MTCH configuration. When the mobile UE is to access the target base station cell, the source base station sends the multicast UE's MBSFN subframe configuration and the multicast MTCH configuration of the redirected target cell (target base station) to the access UE through RRCConnectionRelease signaling, thereby implementing The continuity of the UE for the eMBMS service effectively reduces the delay of the service in terms of performance.

In a preferred embodiment of the present invention, when the information of the MBSFNAreaConfiguration information (such as the MBSFNSubframe information) (the current X2 protocol has been added) and the MTCH configuration is changed at the initial stage of the establishment of the base station, the neighboring base station is changed. The MBSFNAreaConfiguration information is sent to the base station; when the base station receives the MBSFNAreaConfiguration information sent by the neighboring base station, it is stored locally; when the UE in the RRC_CONNECTION state is currently receiving the eMBMS service from the source cell, due to the UE's Move (move to the edge of the neighboring base station), make a decision by the source cell and the neighboring cell to the mobile UE's measurement report and received signal strength indication (Resived Signal Strength Indication, RSSI): select one to support eMBMS according to the cell list.

Multicast MBSFN subframe configuration and multicast MTCH configuration, The UE achieves the continuity of the eMBMS service, and effectively reduces the delay of the service in terms of performance. In short, in the MCE centralized management base station (eNodeB) network deployment, according to the base station (belonging to the same MBMS service area) The interaction information between the UE and the UE in the same MBSFN area provides a method for the UE to receive the same eMBMS service continuity in the area, which effectively reduces the delay of the service.
