Problems solved by technology

[0003] With the development of communication technology, it is now possible to switch AMR voice services between 2G and 3G networks. However, the LTE (Long Term Evolution, long-term evolution) network is currently developing rapidly, and all that is realized under the LTE network is Packet domain service, packet domain service is easier to implement switching under different networks, but AMR voice service is circuit domain service, in order to realize AMR voice service under LTE network, the current common method is to use CS FALLBACK (CircuitSwitched FALLBACK, circuit domain voice fallback), SRVCC (Single Radio Voice Call Continuity, monophonic call continuity), etc., but these methods still use the 3G core network to realize the transmission of AMR voice data, how to use only the LTE network to Achieving AMR voice service is still an unresolved problem

Embodiment Construction

[0024] The embodiment of the present invention provides a method and system for implementing AMR voice service under the LTE standard. Under the LTE standard, the packet data in the packet domain service is transmitted in the channel through the DRB. The embodiment of the present invention specifies that it is dedicated to the transmission of AMR. The specific DRB of voice data and the specific EPS ID (Evolved Packet System ID) specified to represent the AMR voice service. After the mobile terminal is assigned to the specific DRB, it will use the specific DRB to transmit AMR voice data, thereby Realize AMR voice service.

[0025] Such as figure 1 As shown, the method for realizing AMR voice service under the LTE standard provided by the embodiment of the present invention includes:

[0026] Step S101: The network side determines that the mobile terminal needs to establish an AMR voice service of the LTE network;

[0027] Step S102: The mobile terminal receives the allocated physical...

Abstract

The invention discloses method and system for realizing AMR voice service under an LTE system, belonging to a mobile communication technology. A mobile terminal receives distributed physical channel resources returned from the network side after establishing the AMR voice service of the mobile terminal network is confirmed, as well as specific DRB specially for transmitting AMR voice data and specific EPS ID; and the mobile terminal transmits the AMR voice data by using the specific DRB according to synchronous channels of the physical channel resources. As the transmission of the AMR voice data is realized by the set specific DRB specially for transmitting the AMR voice data, the specific DRB is distributed to the mobile terminal from the network side when the mobile network is accessed to the LTE network and requires to realize the AMR voice service, therefore, the AMR voice data can be transmitted through the DRB, and the AMR voice service in the LTE network can be realized.

Description

Technical field [0001] The present invention relates to mobile communication technology, in particular to a method and system for realizing AMR voice service under the LTE standard. Background technique [0002] Currently, mobile communication equipment can accommodate more and more services, but AMR (Adaptive MultiRate, adaptive multi-rate) voice service is still the most important service in mobile communication networks, and the usage rate of AMR voice service is also significantly higher than other services. Usage rate. [0003] With the development of communication technology, AMR voice services can now be switched between 2G and 3G networks. However, the current LTE (Long Term Evolution) network is developing rapidly, and all that is implemented under the LTE network is Packet domain services, packet domain services are relatively easy to switch under different networks, but AMR voice services are circuit domain services, in order to achieve AMR voice services under LTE netw...
