Method and apparatus for allocating bearer resources
First Claim
1. A method for allocating bearer resources comprising:
- a network side storing Evolved Packet System (EPS) bearer information corresponding to all currently activated EPS bearers in advance, wherein the EPS bearer information including bearer identifiers, QoS Class Identifiers (QCIs), current bearer states and priorities corresponding to the currently activated EPS bearers;
when the network side receives a bearer resource allocation request initiated by a user, and a count of currently activated EPS bearers has reached or exceeded a set upper limit, the network side searching the currently activated EPS bearers according to a QCI carried in the bearer resource allocation request;
when the network side does not find any EPS bearer corresponding to the QCI consistent with the QCI carried in the bearer resource allocation request, the network side searching the EPS bearers according to a priority corresponding to the bearer requested by the bearer resource allocation request;
when an EPS bearer with a priority lower than the priority corresponding to the bearer requested by the bearer resource allocation request is found, the network side obtaining a current bearer state corresponding to the found EPS bearer from the EPS bearer information corresponding to all the currently activated EPS bearers, and performing a proprietary bearer modification operation on the found EPS bearer to respond to the bearer resource allocation request only when the obtained current bearer state is the idle state.

Abstract
The invention discloses a method and apparatus for allocating bearer resources, and relates to LTE system in the communication field. The method comprises: when a network side receives a bearer resource allocation request initiated by a user, if the number of currently activated EPS bearers has reached or exceeded a set upper limit, the network side searching the currently activated EPS bearers according to a QCI carried in the bearer resource allocation request, and if an EPS bearer corresponding to a QCI consistent with the QCI carried in the bearer resource allocation request is found, performing a proprietary bearer modification operation on the found EPS bearer to respond to the bearer resource allocation request.

5. An apparatus for allocating bearer resources comprising a processor and a non-transitory computer-readable medium in which a set of processor executable instructions are stored and when the instructions are executed, it causes the processor to perform the steps in following units:
-
a bearer information storing unit storing Evolved Packet System (EPS) bearer information corresponding to all currently activated EPS bearers, wherein the EPS bearer information including bearer identifiers, QoS Class Identifiers (QCIs) and current bearer states corresponding to the currently activated EPS bearers; a receiving unit receiving a bearer resource allocation request initiated by a user, and forward the bearer resource allocation request to a bearer allocating unit; and a bearer allocating unit determining whether a count of currently activated EPS bearers has reached or exceeded a set upper limit after receiving the bearer resource allocation request, and when the count of the currently activated EPS bearers has reached or exceeded the set upper limit, searching an EPS bear in the currently activated EPS bearers according to a QCI carried in the bearer resource allocation request; when an EPS bearer corresponding to the QCI consistent with the QCI carried in the bearer resource allocation request is not found, searching an EPS bearer according to a priority corresponding to the bearer requested by the bearer resource allocation request; when an EPS bearer with a priority lower than the priority corresponding to the bearer requested by the bearer resource allocation request is found, obtaining a current bearer state corresponding to the found EPS bearer from the bearer information storing unit, and performing the proprietary bearer modification operation on the found EPS bearer to respond to the bearer resource allocation request only when the obtained current bearer state is the idle state. - View Dependent Claims (6, 7)
