Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, lift specific embodiment below, the present invention is further detailed explanation.
Carry out in the process in professional beginning of MBMS or MBMS business, network can be by sending PAGING REQUEST or PACKET PAGING REQUEST and PACKETMBMS ANNOUNCEMENT or MBMS ANNOUNCEMENT message to UE, the professional relevant parameter of the relevant MBMS of notice UE, described PAGING REQUEST or PACKET PAGINGREQUEST and PACKET MBMS ANNOUNCEMENT or MBMSANNOUNCEMENT message are the MBMS notification message.
Main thought of the present invention is: network is when UE sends the MBMS notification message, in described MBMS notification message, increase the in-band signalling sign of the channel of indication network sending system message, UE identifies the channel of determining network sending system message according to described in-band signalling, and obtains system message by monitoring determined channel.
Because UE does not know that network passes through under the situation of PACCH sending system message of MBMS radio bearer, can be defaulted as network by BCCH or PBCCH sending system message, therefore, the in-band signalling sign that the present invention is increased in the MBMS notification message only needs indication network whether can pass through the PACCH sending system message of MBMS radio bearer, thereby, if UE receives when indication network passes through the PACCH sending system message of MBMS radio bearer, the channel of determining network sending system message is PACCH, and obtains system message by monitoring PACCH; If UE receives that the channel of determining network sending system message was BCCH or PBCCH when indication network did not pass through the PACCH sending system message of MBMS radio bearer, and obtain system message by monitoring BCCH or PBCCH.
Below in conjunction with two embodiment, introduce method provided by the invention in detail.
Embodiment one:
Among the present invention, the flow process that UE obtains system message comprises following step as shown in Figure 1:
Step 101: network increases an in-band signalling sign in the MBMS notification message that sends to UE, and whether this in-band signalling sign indication network can be by the PACCH sending system message of MBMS radio bearer.
When network passed through the PACCH sending system message of MBMS radio bearer, the in-band signalling sign indication network that is increased was by the PACCH sending system message of MBMS radio bearer; The PACCH sending system message by the MBMS radio bearer when network, and during by BCCH or PBCCH sending system message, the in-band signalling sign indication network that is increased is the PACCH sending system message by the MBMS radio bearer.
Wherein, whether the in-band signalling sign can pass through the PACCH sending system message of MBMS radio bearer with concrete value indication network.For example, the in-band signalling sign can represent that in-band signalling is designated 0 with 1 bit, and indication network does not pass through the PACCH sending system message of MBMS radio bearer; In-band signalling is designated 1, and indication network is by the PACCH sending system message of MBMS radio bearer.
After step 102:UE receives described MBMS notification message, from the MBMS notification message, extract the in-band signalling sign that is increased, UE resolves the in-band signalling sign, determines the channel of network sending system message according to analysis result, and obtains system message by monitoring determined channel.
UE according to the step that the result who resolves the in-band signalling sign obtains system message is: UE is according to the in-band signalling sign of indication network by the PACCH sending system message of MBMS radio bearer, the channel of determining network sending system message is PACCH, monitors PACCH then and obtains system message; UE is the in-band signalling of the PACCH sending system message by MBMS radio bearer sign according to indication network, and the channel of determining network sending system message is BCCH or PBCCH, monitors BCCH then or PBCCH obtains system message.
When whether the in-band signalling sign can pass through the PACCH sending system message of MBMS radio bearer with concrete value indication network, UE determines the channel of network sending system message according to the value of in-band signalling sign, corresponding with the value of the described in-band signalling sign of step 101, the in-band signalling that UE extracts is designated 0, the channel of then determining network sending system message is BCCH or PBCCH, and monitors BCCH or PBCCH obtains system message; The in-band signalling that UE extracts is designated 1, determines that then the channel of network sending system message is PACCH, and monitors PACCH and obtain system message.
By above step 101 and 102, when network passes through PACCH sending system message, owing to carry the in-band signalling sign of network by PACCH sending system message by the MBMS notification message, therefore, UE can in time be known the channel of network sending system message, thereby can in time obtain system message by monitoring PACCH.
Network also can pass through the PACCH issuing page message, at this moment, also can adopt step 101 and 102 described method notice UE networks by the PACCH issuing page message, obtains beep-page message thereby UE can monitor PACCH.

When network passes through PACCH sending system message and beep-page message, perhaps by PACCH sending system message, perhaps by PACCH issuing page message, during perhaps not by PACCH sending system message and beep-page message, UE obtains system message and beep-page message by step as shown in Figure 2, is described in detail as follows described:
Step 201: network increases the in-band signalling sign in the MBMS notification message that sends to UE, and whether this in-band signalling sign indication network can be by the PACCH sending system message and the beep-page message of MBMS radio bearer.
When network by the MBMS radio bearer PACCH sending system message and during beep-page message, the in-band signalling sign indication network that is increased is by the PACCH sending system message and the beep-page message of MBMS radio bearer; Do not pass through the PACCH sending system message of MBMS radio bearer when network, by BCCH or PBCCH sending system message, and during the PACCH issuing page message of network by the MBMS radio bearer, the in-band signalling sign indication network that is increased is by PACCH issuing page message of MBMS radio bearer; Do not pass through the PACCH issuing page message of MBMS radio bearer when network, by BCCH or PBCCH issuing page message, and during the PACCH sending system message of network by the MBMS radio bearer, the in-band signalling sign indication network that is increased is by PACCH sending system message of MBMS radio bearer; Do not pass through the PACCH sending system message and the beep-page message of MBMS radio bearer when network, and during by BCCH or PBCCH sending system message and beep-page message, the in-band signalling sign indication network that is increased is PACCH sending system message and the beep-page message by the MBMS radio bearer.
Wherein, the in-band signalling sign can represent that for example, in-band signalling is designated 0 with 2 bits, and indication network does not pass through the PACCH sending system message and the beep-page message of MBMS radio bearer; In-band signalling is designated 1, and indication network is by the PACCH sending system message of MBMS radio bearer; In-band signalling is designated 2, and indication network is by the PACCH issuing page message of MBMS radio bearer; In-band signalling is designated 3, and indication network is by the PACCH sending system message and the beep-page message of MBMS radio bearer.
After step 202:UE receives described MBMS notification message, from the MBMS notification message, extract the in-band signalling sign that is increased, UE resolves the in-band signalling sign, determine the channel of network sending system message and beep-page message according to analysis result, and obtain system message and beep-page message by monitoring determined channel.
UE according to the step that the result who resolves the in-band signalling sign obtains system message and beep-page message is: UE identifies by the PACCH sending system message of MBMS radio bearer and the in-band signalling of beep-page message according to indication network, the channel of determining network sending system message and beep-page message is PACCH, monitors PACCH then and obtains system message and beep-page message; UE is according to the in-band signalling sign of indication network by the PACCH sending system message of MBMS radio bearer, the channel of determining network sending system message is PACCH, the channel of network issuing page message is BCCH or PBCCH, monitor PACCH then and obtain system message, monitor BCCH or PBCCH and obtain beep-page message; UE is according to the in-band signalling sign of indication network by the PACCH issuing page message of MBMS radio bearer, the channel of determining network sending system message is BCCH or PBCCH, the channel of network issuing page message is PACCH, monitor BCCH then or PBCCH obtains system message, monitor PACCH and obtain beep-page message; UE does not identify by the PACCH sending system message of MBMS radio bearer and the in-band signalling of beep-page message according to indication network, the channel of determining network sending system message and beep-page message is BCCH or PBCCH, monitors BCCH or PBCCH then and obtains system message and beep-page message.
When whether in-band signalling sign can pass through the PACCH sending system message of MBMS radio bearer and beep-page message with concrete value indication network, UE determines the channel of network sending system message and beep-page message according to the value of in-band signalling sign, corresponding with the value of the described in-band signalling sign of step 201, the in-band signalling that UE extracts is designated 0, the channel of then determining network sending system message and beep-page message is BCCH or PBCCH, and monitors BCCH or PBCCH obtains system message and beep-page message; The in-band signalling that UE extracts is designated 1, determines that then the channel of network sending system message is PACCH, and the channel of network issuing page message is BCCH or PBCCH, and monitors PACCH and obtain system message, monitors BCCH or PBCCH and obtains beep-page message; The in-band signalling that UE extracts is designated 2, determines that then the channel of network sending system message is BCCH or PBCCH, and the channel of network issuing page message is PACCH, and monitors BCCH or PBCCH obtains system message, monitors PACCH and obtains beep-page message; The in-band signalling that UE extracts is designated 3, determines that then the channel of network sending system message and beep-page message is PACCH, and monitors PACCH and obtain system message and beep-page message.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
